WO 0 0 / 3 7 4 8 1号ならびに WO O 0 / 4 8 6 0 8号において、 本発明者 ら (阪中、 田中) は下記構造式
In WO 00/3784 81 and WO 0/46806, the present inventors (Sakanaka, Tanaka) have the following structural formula
で示されるジンセノサイ ド R b tの静脈内投与が (6 0 ^ g/日、 1 2 日又 は 6 /Z g /日) 、 中大脳動脈皮質枝 (MCA) 永久閉塞ラッ ト (体重約 3 0 0 g) の大脳皮質梗塞面積を、 ビ一クル (v e h i c l e , 担体) を投与された M C A永久閉塞ラットの 2分の 1以下に縮小せしめること、 及び、 寝たきりの脊髄 損傷ラットの下肢対麻痺を改善し、 同動物を起立せしめることを発明した。 また、 ジンセノサイ ド R b は、 1〜 1 0 0 ί g/m 1 という至適細胞外液濃度域におい て、 神経細胞を始めとするあらゆる細胞のアポト一シスもしくはアポトーシス様 細胞死を抑止することが、 WO 0 0 Z 3 7 4 8 1号において開示されている。 す なわちジンセノサイ ド R b はアポトーシスもしくはアポトーシス様細胞死をきた す疾患の予防、 処置、 治療のための医薬組成物となることが WO 0 0 / 3 7 4 8 1号において開示されている。 Ginsenoside R bt (60 ^ g / day, 12 days or 6 / Z g / day) indicated in the middle cerebral artery cortical branch (MCA) permanent occlusion rat (weight of about 30 0 g) of cerebral cortical infarct area is reduced to less than one-half that of MCA permanently occluded rats receiving vehicle, and improved paraplegia in bedridden spinal cord injured rats And invented to raise the animal. Ginsenoside Rb inhibits apoptosis or apoptosis-like cell death of all cells including neurons in the optimal extracellular solution concentration range of 1 to 100 μg / m1. Are disclosed in WO 00 Z 37481. That is, it is disclosed in WO 00/374781 that ginsenoside Rb is a pharmaceutical composition for preventing, treating, and treating diseases that cause apoptosis or apoptotic cell death.
従って、 低用量 '低濃度のジンセノサイ ド R b の脳梗塞治療効果、 脊髄損傷治 療効果は、 歴史上かってないほど優れたものであることを、 WO 0 0 / 3 7 4 8 1号及び W〇 0 0 / 4 8 6 0 8号において、 本発明者ら (阪中、 田中) が世界に
先がけて見出したと言える。 そこで、 本発明者らはジンセノサイ ド R b!をリード 化合物として利用することにより、 新規に脳梗塞治療用化合物、 神経外傷治療用 化合物、 又は神経細胞保護剤を開発することができると、 WO 0 0/4 8 6 0 8 号に記載している。 しかし、 ジンセノサイ ド R b!をリード化合物として利用する ことにより作成できる化合物の具体例については、 WO 0 0 /4 86 0 8号では 開示されていない。 Therefore, the therapeutic effects of low doses of low concentrations of ginsenoside Rb on the treatment of cerebral infarction and spinal cord injury were far superior to those of the past. 〇 In the issue of 0 0/4 8 6 08, the present inventors (Sakanaka, Tanaka) It can be said that it was found earlier. Therefore, the present inventors have determined that ginsenoside Rb! Can be newly developed as a lead compound, a compound for treating cerebral infarction, a compound for treating nerve trauma, or a nerve cell protective agent can be developed, as described in WO 00/486680. I have. But ginsenoside R b! No specific examples of compounds that can be prepared by utilizing the compound as a lead compound are disclosed in WO 00/48608.
しかも、 ジンセノサイ ド R b iそのものは現時点では合成法すら確立されていな い天然の化合物であるので、 ジンセノサイ ド R b iをリード化合物として新規神経 外傷治療用化合物、 脳梗塞治療用化合物又は脳 · 神経細胞保護剤を作成すること には無理があると当業者には考えられた。 さ らに、 ジンセノサイ ド R b に化学的 修飾を加えてジンセノサイ ド類誘導体を作成するにしても、 ジンセノサイ ド R b の化学構造のうちどの部分を修飾すればジンセノサイ ド R b iと同等もしくはそ れより優れた新規神経外傷治療用化合物、 脳梗塞治療用化合物又は脳 · 神経細胞 保護剤を作成することができるのか、 当初本発明者らにはまったく予想もっかな かった。 なお、 ジンセノサイ ド類ならびにジンセノサイ ド類誘導体の具体例につ いては後述する。 In addition, ginsenoside Rbi itself is a natural compound for which no synthetic method has been established at the present time, so ginsenoside Rbi is a lead compound, a novel compound for treating neurological trauma, cerebral infarction or brain / neural cells. It was thought by those skilled in the art that it was impossible to make a protective agent. Furthermore, even if ginsenoside Rb is chemically modified to produce a ginsenoside derivative, if any part of the chemical structure of ginsenoside Rb is modified, it is equivalent to or equal to ginsenoside Rbi. At first, the present inventors were completely unpredictable as to whether a better novel compound for treating neurological trauma, a compound for treating cerebral infarction or a brain / neuron protective agent could be prepared. Specific examples of ginsenosides and ginsenoside derivatives will be described later.

I found it. In other words, an excellent pharmaceutical agent can be obtained by chemically modifying the double bond of the side chain (force-punch chain) bonded to the steroid-like skeleton (damaran skeleton) of ginsenosides such as ginsenoside Rbi. The present inventors have found that a composition, a composition for external use on the skin (including a composition for cosmetics, a composition for chemical peeling, and a composition for hair growth and hair growth), a composition for external use on mucous membranes, and a composition for regulating growth can be prepared.

After culturing for 16 hours in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal bovine serum, the culture was replaced with a serum-free medium for nerve cell culture containing insulin, transferrin, etc. Cultured for 3-4 days. On day 3 or 4 of culture, sodium nitroprusside (SNP) was added at a concentration of 300 M and incubated for 10 minutes. Thereafter, the culture medium was replaced with Eagle's minimum essential medium (EMEM) containing dihydroxydincenoside Rt (0 to 100 ng / ml) and bovine serum albumin. Sixteen hours after SNP loading, neurons were lysed using a Laemm1i electrophoresis sample buffer, polyacrylamide gel electrophoresis was performed, and the electrophoretic proteins were transferred to a ditrocellulose membrane. The immunoblotting was performed using an antibody against the neuron specific protein MAP2. The results are shown in FIG. The details of the experimental procedure for the MAP2 immunbotlot are described in published papers by the present inventors (Sakanaka and Tanaka) (Wen, T- et al., J. Exp. Med., 188, 635-649, 1998). The upper part of FIG. 2 is a photograph in place of a drawing showing the result of the immunoblot of microtuble-associated protein 2 (MAP 2). The first lane from the left is a control cultured neuron, in which a clear MAP 2 band (ie, a band for a neuronal marker) was observed. SNP treatment caused many neurons to undergo apoptosis or apoptosis-like neuronal death, so the MAP2 band was clearly weakened, as in the second lane from the left. Dihydroxidine senoside Rbi was added to the culture medium at a concentration of 0.001 fg / ml (lane 4) to 100 ηg / ml (lane 10), Apoptosis or apoptosis-like neuronal cell death was clearly suppressed, and as a result, a strong band of MAP2, which is an indicator of neuronal cell survival and / or process elongation, was observed. Therefore, ginsenoside derivatives such as dihydroxy ginsenoside R b can inhibit apoptosis or apoptosis-like cell death of cells, particularly nerve cells, in an optimal extracellular solution concentration range wider than that of ginsenoside R b. It is thought to exert an excellent cytoprotective effect. That is, ginsenoside derivatives such as dihydroxy ginsenoside Rb are described in PCTZ JP 0 0 Z 04 10 2. It is invented to be a pharmaceutical composition for preventing / treating or treating any disease or condition that causes cell death, like the ginsenoside Rbt described above.

Dihydroxy ginsenosides side R b indicates a significant effect at concentrations of 1~ 1 0 8 ί g / m 1. However, it is considered that significant effects can be found by adding the number of cases even at lower concentrations.

以上のごとく、 ジヒ ドロキシジンセノサイ ド R b 又はエポキシジンセノサイ ド R b などのジンセノサイ ド類誘導体は、 ジンセノサイ ド R b iよりも広い至適細 胞外濃度域でアポトーシス様細胞死抑止作用又は抗アポトーシス作用を示すこと が明らかとなった。 また、 その他のジンセノサイ ド類誘導体の 1つであるジヒ ド ロジンセノサイ ド R b も抗アポト一シス作用又はアポト一シス様細胞死抑止作用 を有することが、 P C TZ J P 0 0 / 0 4 1 0 2号及び P C T// J P 0 0/ 0 5 5 54号において発明されている。 従って、 ジンセノサイ ド R b ジヒドロキシ ジンセノサイ ド R b エポキシジンセノサイ ド R b ジヒ ドロジンセノサイ ド
R b iは、 すべて共通の薬理活性、 効果、 効能、 用途を有すると考えられる。 そこ で、 以下の具体例ではこれら 4つの化合物のうち、 ジンセノサイ ド R b 及びジヒ ドロジンセノサイ ド R b!をとりあげ、 これらを静脈内投与、 粘膜外用投与もしく は皮膚外用投与した際に、 優れた創傷治癒促進作用又は組織再生 ·再構築促進作 用がみられることを明らかにすることとする。 もし、 ジンセノサイ ド R b 及び/ 又はジヒドロジンセノサイ ド R b が創傷治癒促進作用、 生体組織 (動物組織、 植 物組織を含む) 再生 ·再構築促進作用を発揮すれば、 ジヒドロキシジンセノサイ ド R b 又はエポキシジンセノサイ ド R b iなどのジンセノサイ ド類誘導体すベて が同様の作用を有すると考えられる。 そこで、 まず、 本発明者らは低用量、 低濃 度のジンセノサイ ド R b iが生体組織の再生 ·再構築に与える効果を調べるため、 たとえば生体組織や細胞の再生現象が容易に観察される皮膚の切開創に対するジ ンセノサイ ド R b iの静脈内持続注入の効果を検討した。 このために、 雄性ウイス ターラッ ト (体重 3 0 0 g程度) を使用した。 同動物は 1 2時間ごとの明暗サイ クル室で飼育し、 水ならびに餌は自由摂取とした。 吸入麻酔下で同動物の背部に 長さ 3 c m程度の切開創を作成し、 ナイロン糸で鏠合後、 約 1時間経過してから ジンセノサイ ド R b : ( 6 0 g ) の生理食塩水溶解液を単回静脈内注入した。 そ の後アルザミニ浸透圧ポンプを用いてジンセノサイ ド R b iを 7 日間静脈内へ持続 注入した ( 6 0 X gノ日) 。 As described above, ginsenoside derivatives such as dihydroxyxenosenoside Rb or epoxy ginsenoside Rb have an inhibitory effect on apoptosis-like cell death or It was revealed that it exhibited an anti-apoptotic effect. In addition, dihydroginsenoside Rb, one of the other ginsenoside derivatives, also has an anti-apoptotic action or an apoptotic-like cell death inhibitory action. And PCT // JP 00/05554. Therefore, ginsenoside R b dihydroxy ginsenoside R b epoxy ginsenoside R b dihydrozin genoside All R bi are considered to have common pharmacological activities, effects, indications, and uses. Therefore, in the specific examples below, among these four compounds, ginsenoside Rb and dihydrozinesenoside Rb! It will be clarified that when these are administered intravenously, topically for mucous membranes or topically for skin, excellent wound healing promoting action or tissue regeneration / reconstruction promoting action is observed. If ginsenoside Rb and / or dihydroginsenoside Rb exert an action of promoting wound healing and an action of promoting regeneration and reconstruction of living tissue (including animal tissue and plant tissue), dihydroxy ginsenoside All ginsenoside derivatives such as R b or epoxy ginsenoside R bi are considered to have a similar effect. First, the present inventors investigated the effect of low dose and low concentration of ginsenoside R bi on regeneration and reconstruction of living tissue. The effect of continuous intravenous infusion of ginsenoside Rbi on incision wounds in rats was examined. For this purpose, male Wistar rats (weight about 300 g) were used. The animals were housed in a light-dark cycle room every 12 hours, with free access to water and food. Make an incision about 3 cm in length on the back of the animal under inhalation anesthesia and dissolve ginsenoside R b: (60 g) in saline approximately 1 hour after joining with nylon thread The fluid was injected once intravenously. Thereafter, ginsenoside R bi was continuously infused intravenously for 7 days using an Alzamini osmotic pump (60 X g days).
なお、 同様の切開創を作成してナイロン糸で縫合した対照動物には、 同量の生 理食塩水のみを静脈内投与した。 In addition, a control animal in which a similar incision was made and sutured with nylon thread was intravenously administered only the same amount of physiological saline.
ジンセノサイ ド R b もしくは生理食塩水の静脈内持続注入終了後 2 日目に、 動 物をペントバルビタールにて麻酔し、 4 %パラホルムアルデヒドを含有する 0 . 1 Mリン酸緩衝液で経心的に灌流固定した。 その後、 切開縫合部位を含む皮膚組 織を採取し、 後固定後常法通りパラフィンに包埋した。 厚さ 5 x m程度のパラフ イン切片を作成してへマトキシリンェォジン (H E ) 染色に供した。 その結果を 第 6図に示す。 第 6図は図面に代わる写真である。 第 6'図 Aはジンセノサイ ド R 投与例、 第 6図 Bは生理食塩水投与例を示している。 また " s " は瘢痕 (s e a r) を示す。 The animals were anesthetized with pentobarbital two days after the end of the continuous intravenous infusion of ginsenoside Rb or saline, and transcardially with 0.1 M phosphate buffer containing 4% paraformaldehyde. Perfusion fixed. Thereafter, the skin tissue including the incision suture was collected, post-fixed, and embedded in paraffin as usual. Paraffin sections having a thickness of about 5 x m were prepared and subjected to hematoxylin-eosin (HE) staining. Figure 6 shows the results. Figure 6 is a photograph replacing the drawing. Fig. 6'A shows an example of ginsenoside R administration, and Fig. 6B shows an example of physiological saline administration. "S" indicates a scar (sear).
第 6図 Aに示されるごとく、 ジンセノサイ ド R b 投与例では、 第 6図 Bの生理
食塩水投与例と比較して、 切開創局部の直近に汗腺、 脂腺、 毛包等の皮膚付属器 が多数観察された。 このことは、 低用量のジンセノサイ ド R b i静脈内投与により 汗腺、 脂腺、 毛包ならびにそれらを構成する細胞が速やかに再生 ·再構築を完了 したことを物語っている。 また、 低用量のジンセノサイ ド R b 投与例では、 生理 食塩水投与例と異なり創傷局部を除いては、 表皮、 真皮、 皮下組織がほぼ正常に 近い状態にまで再生 ·再構築、 もしくは回復していた。 すなわち、 ジンセノサイ ド R b i静脈内投与により創傷を受けた皮膚組織がすみやかに再生 ·再構築し、 そ の結果明らかに創傷治癒が促進されたと言える。 As shown in FIG. 6A, in the ginsenoside Rb administration example, the physiological Compared with the saline-administered case, a number of skin appendages such as sweat glands, sebaceous glands, and hair follicles were observed immediately near the incision wound site. This suggests that sweat glands, sebaceous glands, hair follicles, and the cells constituting them were rapidly regenerated and reconstructed by intravenous administration of low-dose ginsenoside Rbi. Also, in the case of low-dose ginsenoside Rb administration, unlike the saline administration example, the epidermis, dermis, and subcutaneous tissue were regenerated, reconstructed, or recovered to a state close to normal, except for the wound site. Was. In other words, it can be said that intravenous administration of ginsenoside Rbi promptly regenerated and reconstructed wounded skin tissue, and as a result, wound healing was clearly promoted.
一方、 第 6図 Bの生理食塩水投与例では、 瘢痕 (s c ar) 、 いわゆる傷跡が大き く成長してきているが、 損傷を受けた組織の再生はあまり見られない。 即ち、 従 来の創傷治癒においては異常なコラ一ゲンを多く含む瘢痕 (s car) が大きくなる だけで、 損傷を受けた組織が系統的に再生 ·再構築することはなかったのである が、 第 6図 Aにみられるように本発明では、 ジンセノサイ ド R b i投与により、 瘢 痕 (s car) 部分が縮小するのみならず創傷を受けた各々の組織の再生 ·再構築が 行われることが大きな特徴である。 On the other hand, in the physiological saline administration example shown in FIG. 6B, scars, so-called scars, have grown to a large extent, but regeneration of the damaged tissue is hardly observed. That is, in conventional wound healing, only scars containing a large amount of abnormal collagen were increased, and the damaged tissue did not systematically regenerate and reconstruct. As shown in FIG. 6A, in the present invention, administration of ginsenoside Rbi not only reduces the scar part but also regenerates and reconstructs each wounded tissue. It is a big feature.
従って、 ジンセノサイ ド R b の静脈内投与により、 このように皮膚組織の深部 に至るまで組織の再生 ·再構築が進行し、 創傷治癒が順調に進むことから判断す ると、 縫合不全を生じやすい高齢者、 低栄養患者、 糖尿病患者、 免疫不全病患者、 エイズ患者もしくは癌患者の術前術後に天然のジンセノサイ ド類特にはジンセノ サイ ド R b iを静脈内投与しておけば、 優れた効果 ·効能を発揮するものと期待さ れる。 また、 形成外科手術 (いわゆる美容形成外科手術を含む) の前後にあるい は皮膚の損傷、 創傷、 外傷もしくは欠損による疾患の発生後にジンセノサイ ド類 特にはジンセノサイ ド R b を静脈内投与しても、 すぐれた創傷治癒促進効果と組 織再生再構築促進作用を介して、 "より傷が早く確実に治る" ものと思われる。 第. 6図 Aに示すごとくジンセノサイ ド R b 投与例では、 組織再生 ·再構築が順調 に進み、 真皮や皮下組織において膠原線維 (コラーゲン線維) 、 弾性線維、 細網 線維、 細胞外基質が正常に近い状態まで充分に産生分泌されたために、 その結果 として第 6図 Bの生理食塩水投与例よりも、 瘢痕が少なくなつていた。 Therefore, judging from the fact that the intravenous administration of ginsenoside Rb promotes tissue regeneration and reconstruction up to the deep part of the skin tissue and progresses wound healing, suture failure is likely to occur. Intravenous administration of natural ginsenosides, especially ginsenoside Rbi, after preoperative surgery in elderly, malnourished, diabetic, immunodeficient, AIDS or cancer patients · It is expected to be effective. In addition, ginsenosides, especially ginsenoside Rb, may be administered intravenously before or after plastic surgery (including so-called cosmetic plastic surgery) or after the occurrence of disease due to skin damage, wounds, trauma or defects. It is thought that "the wound will heal faster and more reliably" through its excellent wound healing promoting effect and promoting tissue regeneration and reconstruction. As shown in Fig. 6A, in the ginsenoside Rb administration example, tissue regeneration and reconstruction proceeded smoothly, and collagen fibers (collagen fibers), elastic fibers, reticulum fibers, and extracellular matrix were normal in the dermis and subcutaneous tissue. As a result, scarring was reduced as compared with the saline-administered example in FIG. 6B.
次に発明者らは、 皮膚組織の欠損が生じる疾患 (褥創、 皮膚潰瘍、 熱傷、 凍傷、
放射線障害、 開放創、 紫外線障害、 電撃傷等) においても、 低用量のジンセノサ イド R b iの静脈内投与が皮膚組織の再生 ·再構築を促進するかどうかを調べた。 このために、 たとえば雄性ウイス夕一ラッ ト (体重 3 0 0 g程度) を使用して、 吸入麻酔下で同動物の背部に直径 6 m mのパンチバイオプシーを施し開放創を作 成して放置した。 その後、 約 1時間経過してからジンセノサイ ド R b i ( I 2 n g ) の生理食塩水溶解液を単回静脈内投与し、 続いてアルザミニ浸透圧ポンプを 用いてジンセノサイ ド R b iを 7 日間静脈内へ持続注入 ( 1 2 i g /日) した。 なお、 同様の開放創を作成して放置した対照動物には、 同量の生理食塩水のみ を静脈内投与した。 Next, the inventors discovered that diseases that result in loss of skin tissue (pressure sores, skin ulcers, burns, frostbites, It was also investigated whether low-dose intravenous ginsenoside Rbi promotes skin tissue regeneration and remodeling in radiation damage, open wounds, ultraviolet damage, and electric shock. For this purpose, a 6 mm diameter punch biopsy was applied to the back of the animal under inhalation anesthesia using a male wispy rat (weight: about 300 g) to create an open wound and left to stand. . After about 1 hour, a single intravenous injection of a saline solution of ginsenoside Rbi (I 2 ng) was administered, and ginsenoside Rbi was intravenously administered for 7 days using an Alzamini osmotic pump. Continuous infusion (12 ig / day). In addition, the same amount of physiological saline alone was intravenously administered to a control animal in which a similar open wound was prepared and left as it was.
ジンセノサイ ド R b もしくは生理食塩水の静脈内持続注入終了後 2日目に、 動 物をペントバルビタールにて麻酔し、 4 %パラホルムアルデヒ ドを含有する 0 . 1 Mリン酸緩衝液で経心的に灌流固定した。 その後、 開放創を含む皮膚組織を摘 出し、 後固定後常法通りパラフィンに包埋した。 厚さ 5 程度のパラフィン切 片を作成してへマトキシリンェォジン (H E ) 染色に供した。 その結果を第 7図 に示す。 第 7図は図面に代わる写真である。 第 7図 Aはジンセノサイ ド R b i投与 例、 第 7図 Bは生理食塩水投与例を示している。 第 7図 A、 Bの矢印より左側が 健常部を、 第 7図 Aの矢印より右側が再生皮膚組織を、 第 7図 Bの矢印よりお側 が主として瘢痕部 (s c a r , s ) を示している。 第 7図 Aの再生皮膚組織には表皮 下の結合組織 (真皮もしくは皮下組織) に毛包ならびに毛乳頭やそれに付随した 皮脂腺や立毛筋が多数みられ、 再生ならびに再構築した皮膚組織の下に瘢痕 (s c ar , s ) が少し存在している。 The animals were anesthetized with pentobarbital 2 days after the end of the continuous infusion of ginsenoside Rb or saline intravenously, and transcardially with 0.1 M phosphate buffer containing 4% paraformaldehyde. Was fixed by perfusion. Thereafter, the skin tissue including the open wound was excised, post-fixed, and embedded in paraffin as usual. Paraffin sections of about 5 thickness were prepared and subjected to hematoxylin-eosin (HE) staining. Figure 7 shows the results. Figure 7 is a photograph replacing the drawing. FIG. 7A shows an example of ginsenoside Rbi administration, and FIG. 7B shows an example of physiological saline administration. The left side of the arrows in FIGS. 7A and B indicates the healthy part, the right side of the arrow in FIG. 7A indicates the regenerated skin tissue, and the side from the arrow in FIG. 7B indicates mainly the scar (s). I have. In the regenerated skin tissue in Fig. 7A, a large number of hair follicles and dermal papillas and associated sebaceous glands and pilus muscles are found in the connective tissue (dermis or subcutaneous tissue) below the epidermis. There are a few scars (sc ar, s).
第 7図 Aに示されるごとく、 ジンセノサイ ド R b 投与例では、 第 7図 Bの生理 食塩水投与例と比較して、 上皮化も充分起きており、 乳頭を有する真皮の結合組 織、 皮下組織の再生 ·再構築がほぼ正常組織に近い状態までに進行していた。 ま た、 ジンセノサイ ド R b i投与例では、 生理食塩水投与例と異なり、 開放創の再生 皮膚組織内に毛包、 毛乳頭、 脂腺、 立毛筋、 汗腺等の皮膚付属器が豊富に認めら れ、 血管網もほぼ正常組織に近い状態まで再生 ·再構築もしくは回復していた。 おそらく、 このような表皮、 真皮の結合組織、 真皮の乳頭、 皮下組織、 皮膚付属 器、 血管の再生 ' 再構築に伴い、 開放創作成時に切断された末梢神経もジンセノ

In addition, in the case of ginsenoside Rbi administration, unlike in the case of administration of physiological saline, regenerating open wounds Abundant skin appendages such as hair follicles, dermal papilla, sebaceous glands, pilus muscle, and sweat glands were observed in the skin tissue. As a result, the vascular network had been regenerated, reconstructed, or recovered to a state close to normal tissue. Perhaps with the regeneration of such epidermis, connective tissue of the dermis, papillary dermis of the dermis, subcutaneous tissue, skin appendages, and blood vessels', the peripheral nerves that were cut at the time of creation of open wounds were also ginseno. It was considered that regeneration was caused by intravenous administration of Side Rbt. As shown in Fig. 7A, tissue regeneration and remodeling proceeded smoothly in the low-dose ginsenoside RbL-administered cases, and collagen fibers (collagen fibers), dermal fibers, reticular fibers, and cells in the dermis and subcutaneous tissues. The extramatrix was sufficiently produced and secreted to a state close to normal, and as a result, scarring was smaller than in the saline-administered example in FIG. 7B.
次に本発明者らは、 皮膚の開放創を作成する前にあらかじめジンセノサイ ド R b Lを静脈内投与したときも皮膚組織の再生 ·再構築が促進するかどうかを調べた < このために、 雄性ウィスターラッ ト (体重 3 0 0 g程度) に吸入麻酔下でジンセ ノサイ ド R b t ( 1 2 g ) の生理食塩水溶解液を単回静脈内投与し、 続いてアル ザミニ浸透圧ポンプを用いてジンセノサイ ド R b を 4日間静脈内へ持続注入 ( 1 日) した。 その後、 吸入麻酔下で同動物の背部に直径 6 mmのパンチバ ィォプシ一を施し開放創を作成するとともに、 ジンセノサイ ド R b iの静脈内持続 注入をさらに 3 日間継続した。 Next, the present inventors examined whether ginsenoside R b L was administered intravenously in advance before creating open wounds on the skin, and whether regeneration / reconstruction of skin tissue was promoted. A single intravenous injection of a saline solution of ginsenoside Rbt (12 g) was administered to a male Wistar rat (body weight: about 300 g) under inhalation anesthesia, followed by an Alzamini osmotic pump. Ginsenoside Rb was continuously infused intravenously for 4 days (1 day). Then, under inhalation anesthesia, a 6 mm diameter punch biopsy was applied to the back of the animal to create an open wound, and continuous intravenous infusion of ginsenoside Rbi was continued for another 3 days.
なお、 同様の開放創を作成して放置した対照動物には、 同量の生理食塩水のみ を静脈内投与した。 Control animals left with similar open wounds were given the same volume of saline only intravenously.
ジンセノサイ ド R b iもしくは生理食塩水の静脈内持続注入終了後 2日目 (すな わち開放創作成後 5日目) に、 動物をペントバルビタールにて麻酔し、 4 %パラ ホルムアルデヒドを含有する 0 . 1 Mリン酸緩衝液で経心的に灌流固定した。 そ の後、 開放創を含む皮膚組織を摘出し、 後固定後常法通りパラフィンに包埋した。 厚さ 5 m程度のパラフィン切片を作成してへマトキシリンェォジン (H E) 染 色に供した。 その結果を第 8図に示す。 第 8図は図面に代わる写真である。 第 8 図 Aはジンセノサイ ド R b 投与例、 第 8図 Bは生理食塩水投与例を示している。 On the second day after the end of the continuous intravenous infusion of ginsenoside Rbi or saline, the animals were anesthetized with pentobarbital on day 5 after the preparation of the open wound and contained 4% paraformaldehyde. Perfusion fixation was performed transcardially with 1 M phosphate buffer. Thereafter, the skin tissue including the open wound was excised, post-fixed, and embedded in paraffin as usual. Paraffin sections of about 5 m thickness were prepared and subjected to Hematoxylin Eosin (HE) staining. Figure 8 shows the results. Figure 8 is a photograph replacing the drawing. FIG. 8A shows an example of ginsenoside Rb administration, and FIG. 8B shows an example of physiological saline administration.

第 8図 Aに示されたごとく、 ジンセノサイ ド R b i投与例では、 開放創作成後 5 日目には既に痂皮の下に明らかな表皮 (重層扁平上皮組織) が再生 '再構築して おり、 表皮 (重層扁平上皮) 直下には赤血球で満たされた太い再生血管もしくは 新生血管が分布するとともに、 同血管から枝分れしたと思われる比較的細い血管
が真皮の結合組織や皮下組織内に密に存在していた。 一方、 第 8図 Bに示された ごとく、 生理食塩水投与例では、 開放創作成後 5 日目においても痂皮の下の表皮 再生は極めて不完全であり、 非常に薄い表皮の直下にある再生血管も、 ジンセノ サイ ド R b i静脈内投与例と比較して明らかに細かった。 そのため将来瘢痕になる と考えられる表皮下の結合組織には極めて細い血管が少数散見されるのみであつ た。 従って、 ジンセノサイ ド R b iの静脈内投与により、 皮膚組織の再生 ·再構築 が明らかに促進され、 開放創によってひとたび破綻 ·切断された血管の再生 ·新 生 ·再構築もジンセノサイ ド R t の静脈内投与により促進されることが発明され たことになる。 また、 ここで忘れてはならないことは、 第 8図 Aのごとくジンセ ノサイ ド R b i投与例で開放創作成後 5日目にみられた表皮 (重層扁平上皮) 直下 の太い血管が、 開放創作成後 9 日目には第 7図 Aのごとくほぼ退縮し、 同部には 乳頭を有する真皮の結合組織がみられることである。 すなわち、 ジンセノサイ ド R b i投与例では、 開放創作成後早期には血管の再生もしくは新生が起こり、 皮膚 組織の再生 ·再構築が完成するにつれて、 血管の再構築が生じることを物語って いる。 1つの化合物が組織再生 ·再構築という複雑な生命現象を、 かくも鮮やか に成し遂げることを証明した本発明は、 まさに人類史上初のものであると言える。 なお、 健常組織においては、 ジンセノサイ ド R b 投与例と生理食塩水投与例との 間で、 明らかな相異は認められなかった。 このことは、 低用量のジンセノサイ ド R b を静脈内へ持続投与しても健常組織にはさしたる影響を与えず、 病変組織や 損傷 (創傷) 組織にのみ好ましい効果をもたらすことを支持している。 すなわち、 ジンセノサイ ド類特にジンセノサイ ド R b は副作用の少ない医薬組成物と言える ( このように、 開放創によってひとたび欠損した皮膚組織がジンセノサイ ド R b の静脈内投与により速やかにかつ正常に近い状態にまで再生 ·再構築するという 本実験結果は、 ジンセノサイ ド類特にジンセノサイ ド R b が皮膚欠損部周辺の表 皮細胞、 表皮角化細胞、 角質細胞、 メルケル細胞、 ランゲルハンス細胞、 幹細胞、 線維芽細胞、 間葉系細胞、 血管内皮細胞、 立毛筋の細胞、 血管平滑筋細胞の分裂、 増殖、 移動、 分化、 接着、 ならびに表皮細胞の毛包、 汗腺、 皮脂腺細胞への分化 を促進することをも明らかにしている。 しかも前述の各種細胞、 末梢神経、 血管 がジンセノサイ ド R b i投与により有機的に系統立てて再生 ·再構築した結果、 正
常皮膚組織に近い状態にまで皮膚の開放創が速やかに回復するということが発明 されたことになる。 すなわち、 低用量のジンセノサイ ド類特にはジンセノサイ ドAs shown in Fig. 8A, in the case of ginsenoside Rbi administration, the clear epidermis (stratified squamous epithelium) under the crust was already regenerated and reconstructed on the 5th day after the creation of the open wound. The epidermis (stratified squamous epithelium) has a large regenerative blood vessel or new blood vessel filled with red blood cells underneath, and a relatively thin blood vessel that seems to branch off from the blood vessel. Were densely present in the connective and subcutaneous tissues of the dermis. On the other hand, as shown in Fig. 8B, in the saline-administered example, the epidermis regeneration under the crust was extremely incomplete even on the fifth day after the creation of the open wound, and was just below the very thin epidermis. The regenerative blood vessels were also clearly smaller than those of ginsenoside Rbi administered intravenously. As a result, only a small number of extremely thin blood vessels were found in the connective tissue under the epidermis, which is thought to become scar in the future. Therefore, the intravenous administration of ginsenoside R bi clearly promotes the regeneration and remodeling of skin tissue, and once open rupture, regeneration of cut blood vessels, neoplasia, and remodeling, the ginsenoside R t vein is also used. It was invented that it would be facilitated by internal administration. Also, it is important to remember that the thick blood vessels just below the epidermis (stratified squamous epithelium) seen on the 5th day after the creation of open wounds in the case of ginsenoside Rbi administration as shown in Fig. 8A On the ninth day after puberty, it almost regressed, as shown in Fig. 7A, and the dermal connective tissue with papillae was found in the same area. In other words, in the case of ginsenoside Rbi administration, the regeneration or renewal of blood vessels occurs early after the creation of the open wound, and the revascularization occurs as the regeneration and reconstruction of the skin tissue is completed. The present invention, which proves that one compound can achieve the complex biological phenomenon of tissue regeneration and reconstruction so vividly, is truly the first in human history. In healthy tissues, no clear difference was observed between ginsenoside Rb-administered patients and saline-administered patients. This suggests that continuous intravenous administration of low doses of ginsenoside Rb has no appreciable effect on healthy tissues, but has favorable effects only on diseased or damaged (wounded) tissues. . In other words, ginsenosides, especially ginsenoside Rb, can be said to be a pharmaceutical composition with few side effects (in this way, skin tissue once deficient due to an open wound can be quickly and almost brought into a normal state by intravenous administration of ginsenoside Rb. The results of this experiment that ginsenosides, especially ginsenoside R b, were regenerated and reconstituted into epidermal cells, epidermal keratinocytes, keratinocytes, Merkel cells, Langerhans cells, stem cells, fibroblasts, It also reveals that it promotes the division, proliferation, migration, differentiation, and adhesion of mesenchymal cells, vascular endothelial cells, cells of the pilo muscularis, and vascular smooth muscle cells, and differentiation of epidermal cells into hair follicles, sweat glands, and sebaceous gland cells In addition, the aforementioned cells, peripheral nerves, and blood vessels are organically regenerated and reconstructed by administering ginsenoside Rbi. As a result, positive It has been invented that the open wound of the skin is quickly recovered to a state close to the normal skin tissue. That is, low dose ginsenosides, especially ginsenosides
R b iの静脈内持続投与により、 皮膚欠損部に新たに再生した表皮細胞や線維芽細 胞が正常の皮膚組織に類似した態様で配列し、 細胞外基質、 膠原線維、 弾性線維、 細網線維なども正常皮膚組織に近い状態にまで再生 ·再構築されると言える。 本 実験結果 (第 7図 A、 第 8図 A) に示されたごとく、 ジンセノサイド Rb の静脈 内投与により皮膚の開放創 (皮膚欠損部) において表皮組織のみならず真皮や皮 下組織にいたるまで再生 ·再構築が促進されるので、 ひとたび開放創が上皮化さ れたのちに再び同部に外傷が負荷されても、 ジンセノサイ ド R b i投与により上皮 化された開放創部では上皮組織の剥離が生じにくいものと期待される。 By continuous intravenous administration of Rbi, newly regenerated epidermal cells and fibroblasts are arranged in a manner similar to normal skin tissue at the skin defect, and extracellular matrix, collagen fibers, elastic fibers, reticulum fibers It can be said that these are regenerated and reconstructed to a state close to normal skin tissue. As shown in the results of this experiment (Figs. 7A and 8A), intravenous administration of ginsenoside Rb caused not only epidermal tissue but also dermis and subcutaneous tissue in open wounds (skin defect) on the skin. Since regeneration and remodeling are promoted, even if the open wound becomes epithelialized and then trauma is again applied to the same area, epithelial tissue detachment occurs in the open wound that has been epithelialized by ginsenoside Rbi administration. It is expected that it will hardly occur.
一方、 第 7図 Bや第 8図 Bに示すごとく生理食塩水投与例では、 外見上上皮化 は起きていても、 真皮や皮下組織の再生 ·再構築を伴わず瘢痕が形成されている ので、 同部に軽い外力が加わっただけで容易に表皮組織が剥離する恐れがある。 ちなみに、 発明者らの経験によれば表皮増殖因子 (epidermal growth factor, E G F ) 、 血小板由来増殖因子 (platele卜 derived growth factor, PDGF) や 塩基性線維芽細胞成長因子 (basic fibroblast growth factor, b F G F ) をラ ッ 卜皮膚の開放創局所に噴霧もしくは塗布しても、 それらの創傷治癒促進効果は 低用量のジンセノサイ ド R b iの静脈内持続投与の効果に遠く及ばない。 このよう に低用量のジンセノサイ ド R b が単独で皮膚組織の再生 ·再構築もしくは創傷治 癒をかくもあざやかに成しとげるということは、 皮膚組織の創傷治療もしくは再 生 ·再構築にかかわるサイ トカイン類、 成長因子類又は増殖因子類及びそれらの 受容体又は転写因子類 (たとえば、 EGF、 TGF—; 3 1、 TG F— ひ、 エリス ロポェチン、 e t s— 1 0、 E r b— B 3、 ND F、 EGF R、 TGF R、 F G FR、 PD GF R、 HGFR、 KGFR、 F GF、 VE GF、 PDGF - B B、 TGF— / 3 1、 P DGF— AB、 VEGF R、 アンジォポェチン、 T i e、 e p h r i n— B2、 E p h - 4 B、 CXC R 4、 s h e , S C L、 S C F、 I G F R■ I GF, KGF、 HGF、 P D GF, TG F— |3 2、 TGF— |3 3、 F GF— 2、 H I F、 U— PA、 1:一 PA等) の産生や血球成分 .血漿成分の機能なども低用 量のジンセノサイ ド類特にはジンセノサイ ド R b により調節されていることを物

Me d . , 341 , 738-746 , 1 999 ) 及び渋谷らの文献 ( 「実験医学」 、 1 7卷、 6号、 1 9 9 9年、 企画、 渋谷正史;羊土社) に記述されたごとく、 創傷治癒もしくは組織再 生 ·再構築にかかわる複雑な生命現象を、 低用量 ·低濃度のジンセノサイ ド類特 にはジンセノサイド R b iが単独ですベて成しとげたといえる。 On the other hand, as shown in Fig. 7B and Fig. 8B, in the case of administration of physiological saline, scars were formed without regenerating and reconstructing the dermis and subcutaneous tissue, even though the epithelization was apparently occurring. However, epidermal tissue may be easily exfoliated simply by applying a slight external force to the same part. Incidentally, according to the experience of the inventors, epidermal growth factor (EGF), platelet derived growth factor (PDGF), basic fibroblast growth factor (b FGF) ) Is applied or sprayed to open wounds on rat skin, but their effect on promoting wound healing is far from the effect of continuous intravenous administration of low doses of ginsenoside Rbi. Such a low dose of ginsenoside Rb alone can regenerate and regenerate skin tissue alone or revitalize wound healing, which means that ginsenoside Rb alone has a role in skin treatment or regeneration / reconstruction of skin tissue. Tokines, growth factors or growth factors and their receptors or transcription factors (eg, EGF, TGF—; 31, TGF—H, erythropoietin, ets—10, Erb—B3, ND F, EGF R, TGF R, FG FR, PD GFR, HGFR, KGFR, F GF, VE GF, PDGF-BB, TGF- / 31 / PDGF-AB, VEGF R, Angiopoietin, Tie, ephrin- B 2, E ph - 4 B , CXC R 4, she, SCL, SCF, IGFR ■ I GF, KGF, HGF, PD GF, TG F- | 3 2, TGF- | 3 3, F GF- 2, HIF , U-PA, 1: 1-PA, etc.) and the functions of blood cells and plasma components are also regulated by low-dose ginsenosides, especially ginsenoside Rb. The thing Talking. A review of Singer, A.J., Clark, and RAF (New Engl. J. Med., 341, 738-746, 1999) and the literature of Shibuya et al. As described in “Medical Science”, Vol. 17, No. 6, 1989, planning, Masashi Shibuya; Yodosha), it is possible to reduce complex life phenomena related to wound healing or tissue regeneration and reconstruction by using low doses. · It can be said that low concentration ginsenosides, especially ginsenoside R bi, were successfully achieved alone.
本実験結果では、 皮膚欠損を生じる開放創を作成した後に低用量のジンセノサ イ ド R b iを静脈内へ持続投与することにより、 皮膚組織の再生 ·再構築が促進さ れ、 創傷治癒が顕著に進んだ。 このことは、 低用量のジンセノサイ ド類特にジン セノサイ ド R b iの静脈内持続投与が皮膚欠損を生ずる他の疾患 (たとえば褥創、 皮膚潰瘍、 熱傷、 凍傷、 放射線障害、 レーザー傷害、 水疱性皮膚疾患、 紫外線障 害、 電搫傷、 日射病、 皮膚の外傷等) にも効果,効能を示すことを物語っている。 また、 皮膚のみならず、 他の臓器 ·組織の一部が欠損する疾患 (たとえば消化性 潰瘍、 潰瘍性大腸炎、 粘膜びらん、 粘膜潰瘍、 消化管粘膜びらん、 膣粘膜びらん、 膣粘膜潰瘍、 慢性胃腸炎、 急性胃腸炎、 クローン病、 ベーチェット病、 鼓膜損傷、 角膜損傷、 角膜びらん、 骨粗鬆症、 変型性膝関節症、 角膜潰瘍、 骨欠損、 膀胱 - 尿道■ 陰茎損傷等) にもジンセノサイ ド類特にはジンセノサイ ド R b iの静脈内投 与や局所投与が有効であるときれる。 また、 前述の疾患において、 ジンセノサイ ド R b などのジンセノサイ ド類を点鼻投与、 揷肛投与、 揷膣投与、 点耳投与、 点 眼投与、 舌下投与等してもよい。 もちろん、 各種臓器 ·組織の病理組織学的変化 をきたすその他のあらゆる疾患に対して、 低用量のジンセノサイ ド類特にジンセ ノサイ ド R b iは病理組織学的変化をきたした臓器 ·組織の再生 ·再構築を促する ことにより、 効果 ·効能を示す。 このような病理組織学的変化をきたす疾患や病 態として、 創傷、 熱傷、 外傷、 咬傷、 皮膚潰瘍、 褥創はもとより成書 (今日の治 療指針 ;監修、 日野原重明、 阿部正和 ; 医学書院; 1 9 9 5 ) に記載されたすベ ての疾患や病態ならびに厚生省が指定する特定疾患が考えられる。 The results of this experiment show that the continuous administration of a low dose of ginsenoside Rbi intravenously after creating an open wound that causes skin defects promotes regeneration and remodeling of skin tissue, and markedly improves wound healing. Advanced. This indicates that low-dose ginsenosides, especially those that cause continuous skin deficits due to continuous intravenous administration of ginsenoside R bi (eg, pressure sores, skin ulcers, burns, frostbite, radiation damage, laser injury, vesicular skin) It shows that it is effective and effective for diseases, ultraviolet rays, electrical injuries, sunstroke, skin trauma, etc. In addition, diseases in which not only the skin but also other organs and tissues are partially lost (for example, peptic ulcer, ulcerative colitis, mucosal erosion, mucosal ulcer, gastrointestinal mucosal erosion, vaginal mucosal erosion, vaginal mucosal ulcer, chronic Ginsenosides, especially gastroenteritis, acute gastroenteritis, Crohn's disease, Behcet's disease, tympanic membrane damage, corneal damage, corneal erosion, osteoporosis, dysplastic osteoarthritis, corneal ulcer, bone loss, bladder-urethra ■ penis damage, etc. Is when intravenous or local administration of ginsenoside Rbi is effective. In addition, in the above-mentioned diseases, ginsenosides such as ginsenoside Rb may be administered by nasal administration, anal administration, vaginal administration, ear administration, ophthalmic administration, sublingual administration, or the like. Of course, for all other diseases that cause histopathological changes in various organs and tissues, low-dose ginsenosides, especially ginsenoside Rbi, can be used to regenerate and regenerate organs and tissues that have histopathological changes. The effect and efficacy are shown by encouraging construction. Diseases and conditions that cause such histopathological changes include wounds, burns, trauma, bites, skin ulcers, pressure ulcers, as well as books (current treatment guidelines; supervision, Hinohara Shigeaki, Abe Masakazu; Medical Shoin) All the diseases and conditions described in 1995) and specific diseases specified by the Ministry of Health and Welfare are considered.
ラッ ト皮膚の開放創を用いた本実験において、 低用量のジンセノサイド R b の 静脈内持続投与は顕著に皮膚組織の再生 ·再構築を促進した。 改めて言うまでも なく、 皮膚は表皮 (重層扁平上皮) 、 結合組織、 血管、 神経、 分泌腺等、 他の臓 器や組織と共通した構成要素を持っている。 従って、 低用量のジンセノサイ ド類
特にはジンセノサイ ド R b:の静脈内持続投与が皮膚組織の再生 ·再構築を顕著に 促進したという本実験事実は、 低用量のジンセノサイ ド R b iの静脈内持続投与が 他のあらゆる臓器や組織 (たとえば肝、 腎、 心臓、 消化管、 唾液腺、 滕、 筋肉組 織、 呼吸器、 感覚器、 泌尿生殖器、 内分泌器官、 骨、 軟骨、 角膜、 粘膜、 口腔粘 膜、 神経組織等) の再生もしくは再構築をも促進することを示している。 すなわ ち、 肝部分切除術後、 クラッシュシンドローム、 急性尿細管壊死、 急性腎不全、 肝炎、 腎炎、 滕部分切除、 消化性潰瘍、 潰瘍性大腸炎、 クローン病、 角膜損傷、 角膜びらん、 角膜潰瘍、 口内炎、 ァフタ性口内炎、 骨粗鬆症、 変型性膝関節症、 口腔粘膜損傷、 鼓膜損傷等の病態において、 当該臓器の再生もしくは再構築を促 進するために、 ジンセノサイ ド類特にジンセノサイド R b iの静脈内投与もしくは 局所投与が有効であると考えられる。 In this experiment using open wounds on rat skin, continuous low-dose intravenous administration of ginsenoside Rb significantly promoted regeneration and remodeling of skin tissue. Needless to say, the skin has components common to other organs and tissues, such as the epidermis (stratified squamous epithelium), connective tissue, blood vessels, nerves, and secretory glands. Therefore, low dose ginsenosides In particular, the fact that the continuous intravenous administration of ginsenoside Rb: significantly promoted the regeneration and remodeling of skin tissue was demonstrated by the fact that the continuous intravenous administration of low-dose ginsenoside Rbi was effective in all other organs and tissues. Regenerate or regenerate (eg liver, kidney, heart, digestive tract, salivary gland, tent, muscle tissue, respiratory organs, sensory organs, urogenital organs, endocrine organs, bone, cartilage, cornea, mucous membrane, oral mucosa, nerve tissue, etc.) This indicates that restructuring is also promoted. That is, after partial hepatectomy, crash syndrome, acute tubular necrosis, acute renal failure, hepatitis, nephritis, Teng partial resection, peptic ulcer, ulcerative colitis, Crohn's disease, corneal injury, corneal ulcer, corneal ulcer In the pathology of stomatitis, phlegm-stomatitis, osteoporosis, knee osteoarthritis, oral mucosal damage, eardrum damage, etc., ginsenosides, especially ginsenoside R bi, are used to promote regeneration or reconstruction of the organ concerned. Administration or topical administration may be effective.
また、 本発明のジンセノサイ ド R b iは、 開放創による皮膚欠損部位において血 管の再生 '再構築、 末梢神経再生、 毛包、 汗腺、 脂腺の再生をも促進することが 本実験において明らかにされた。 これらのことより、 低用量 '低濃度のジンセノ サイ ド類特にジンセノサイ ド R b は血流障害を主症状とする疾病 (大動脈炎症候 群、 末梢動脈閉塞症、 閉塞性血栓血管炎、 閉塞性動脈硬化症、 レイノ一病、 レイ ノー症候群、 血栓症、 D I C、 狭心症、 心筋梗塞、 肺塞栓、 脳梗塞、 肝 · 腎 ·心 虚血再灌流障害、 脳血管障害、 痔疾、 もやもや病等) の予防、 治療、 処置剤、 発 毛 ·育毛用組成物、 脱毛 (円形脱毛症、 男性型脱毛症、 び慢性脱毛症) 'の進行予 防 ·治療 ·処置剤あるいは末梢神経障害や神経痛の予防、 治療、 処置剤として、 利用可能であると考えられる。 In this experiment, ginsenoside Rbi of the present invention also clearly promotes regeneration of blood vessels, reconstruction of peripheral nerves, regeneration of hair follicles, sweat glands, and sebaceous glands at sites of skin defects caused by open wounds. Was done. Based on these findings, low doses and low concentrations of ginsenosides, especially ginsenoside Rb, are diseases that are mainly caused by impaired blood flow (aortic inflammation group, peripheral arterial occlusion, obstructive thromboangiitis, obstructive artery). Sclerosis, Reino's disease, Raynaud's syndrome, thrombosis, DIC, angina pectoris, myocardial infarction, pulmonary embolism, cerebral infarction, liver, kidney, cardiac ischemia / reperfusion injury, cerebrovascular disorder, hemorrhoids, moyamoya disease, etc.) Prevention, treatment and treatment of hair loss, hair growth and hair growth composition, prevention of progression of alopecia (alopecia areata, androgenetic alopecia, and chronic alopecia), treatment and treatment or treatment of peripheral neuropathy and neuralgia It can be used as a therapeutic or therapeutic agent.
以上の実験結果から、 低用量 ·低濃度のジンセノサイ ド類特にジンセノサイ ド R b i又はその塩を含有してなる静脈内投与用製剤が、 優れた創傷治癒促進作用も しくは皮膚組織再生 ·再構築促進効果を介して、 皮膚の損傷、 創傷 (切開創、 開 放創) 、 外傷もしくは欠損による疾患又は皮膚の病理組織学的変化をきたす疾患 の治療、 予防、 処置に有用となることが明らかにされた。 Based on the above experimental results, low-dose and low-concentration ginsenosides, especially intravenous preparations containing ginsenoside Rbi or a salt thereof, have excellent wound healing promoting effects or skin tissue regeneration / reconstruction It is clear that the promoting effect is useful for the treatment, prevention and treatment of skin damage, wounds (incision wounds, open wounds), diseases caused by trauma or defects or diseases that cause histopathological changes in the skin. Was done.
本発明の低用量 ·低濃度のジンセノサイ ド類特にジンセノサイ ド R b i又はその 塩は、 薬用人蔘の成分として知られており、 副作用の極めて少ない物質である。 次に本発明者らは、 皮膚組織の欠損が生じる疾患 (褥創、 皮膚潰瘍、 熱傷、 凍
傷、 放射線障害、 開放創、 紫外線障害、 電撃障害等) において、 ジンセノサイ ドThe low-dose and low-concentration ginsenosides of the present invention, particularly ginsenoside Rbi or a salt thereof, is known as a component of ginseng and is a substance having extremely few side effects. Next, the present inventors consider the diseases that cause skin tissue deficiency (pressure sores, skin ulcers, burns, Ginsenosides in wounds, radiation damage, open wounds, UV damage, electric shock, etc.
R b の皮膚外用投与が効果 ·効能を発揮するかどうかを調べた。 このため、 たと えば雄性ウィスターラッ ト (体重 3 0 0 g程度) を使用して、 吸入麻酔下で同動 物の背部を剃毛した後に直径 6 mmのパンチバイオプシーを施し開放創を 3ケ所 作成した。 そのうち 2ケ所には 0. 0 1重量%もしくは 0 . 0 0 1重量%のジン セノサイ ド R b iを含有する眼科用白色ワセリン (プロぺト) を連日 0. l g単回 塗布し、 残りの開放創には同量の眼科用白色ワセリン (プロぺト) のみを塗布し た。 開放創作成後、 9 日目に創部を含む皮膚を写真撮影した。 さらに、 本発明者 らは同様の方法で 0. 0 0 0 1重量%、 0 . 0 0 0 0 1重量%もしくは 0 . 0 0 0 0 0 1重量%のジンセノサイド R b 皮膚外用塗布の効果も調べた。 なお、 実験 動物は写真撮影直前に麻酔薬により安楽死させ、 写真撮影したのちに創傷部を採 取するかもしくは創傷部を採取したのちに写真撮影を実施した。 その後創傷部組 織を固定液中で保存した。 結果を第 9図及び第 1 0図に示す。 第 9図及び第 1 0 図は図面に代わる写真である。 It was examined whether topical administration of R b to the skin exerts its effects. For this reason, for example, using a male Wistar rat (weighing about 300 g), the back of the animal was shaved under inhalation anesthesia, and then a punch biopsy with a diameter of 6 mm was applied to create three open wounds. did. Two of them were coated with 0.1% by weight or 0.01% by weight of ophthalmic white petrolatum (prototype) containing 0.11% by weight of ginsenoside Rbi. Only the same amount of ophthalmic white petrolatum (prototype) was applied to the wound. On day 9 after the creation of the open wound, a photograph of the skin including the wound was taken. Furthermore, the present inventors have found that the effect of applying 0.001% by weight, 0.001% by weight or 0.001% by weight of ginsenoside R b external application to the skin in a similar manner. Examined. The experimental animals were euthanized with an anesthetic just before taking the photograph, and the photograph was taken and the wound was taken or the wound was taken and photographed. Thereafter, the wound tissue was stored in a fixative. The results are shown in FIG. 9 and FIG. Figures 9 and 10 are photographs replacing the drawings.
第 9図の上から 1番目が開放創作成後プロぺトのみを外用投与 (外用塗布) し たものであり、 赤い開放創 (白黒写真では黒い開放創) が目立つ。 第 9図の上か ら 2番目が 0 . 0 0 1重量%のジンセノサイ ド R b iを含有するプロぺトを外用塗 布 (皮膚外用投与) したものであるが、 上から 1番目のプロぺトのみを外用塗布 したものに比べて開放創面積がやや縮小していた。 一方、 0. 0 1重量%のジン セノサイ ド R b iを含有するプロぺトを外用塗布 (皮膚外用投与) された上から 3 番目の開放創は、 上から 1番目の対照と比べて差異は認められなかった。 すなわ ち 0. 0 1重量%のジンセノサイ ド R b を含有するプロぺト (すなわち軟膏基剤 の 1 gあたり 1 0 0 gのジンセノサイ ド R b を含有するプロべト) は、 開放創 に塗布しても皮膚組織の再生 ·再構築を顕著には促進せず、 従って創傷治癒もそ れほど進まず、 その結果瘢痕形成もそれほど抑止しないと考えられる。 The first from the top of Fig. 9 is an external application (external application) of only the plot after preparation of the open wound, and the red open wound (black open wound in the black and white photograph) is conspicuous. The second from the top in Fig. 9 is a topical application (external application to the skin) of a protein containing 0.001% by weight of ginsenoside Rbi. The open wound area was slightly reduced as compared to the case where only topical application was applied. On the other hand, the third open wound from the top, which had been topically applied (external application to the skin) with a 0.1% by weight ginsenoside Rbi-prote, showed no difference compared to the first control from the top. I was not able to admit. That is, a protocol containing 0.01% by weight of ginsenoside Rb (ie, a protocol containing 100 g of ginsenoside Rb per gram of ointment base) can be used for open wounds. It is believed that application does not significantly promote regeneration and remodeling of skin tissue, and therefore does not significantly promote wound healing and, as a result, scar formation.
また、 第 1 0図の上から 2番目と 3番目に示したごとく、 0 . 0 0 0 0 1重量 % ( 1 0— 5重量%) もしくは 0 . 0 0 0 0 0 1重量% ( 1 0— 6重量%) のジンセ ノサイ ド R b iを含有するプロぺトは、 0. 0 0 0 1重量%のジンセノサイド R b iを含有するプロぺトよりも優れた効果を示した。 このことは、 低濃度のジンセノ
サイ ド R b iからなる皮膚外用剤を開放創に外用塗布もしくは外用噴霧しても、 低 用量のジンセノサイ ド R b の静脈内持続投与とほぼ同じ効果 ·効能が得られるこ とを明らかにしている。 また 0 . 0 0 0 0 0 1重量%のジンセノサイ ド R b の皮 膚外用投与により、 再生した開放創部より明らかな発毛が観察された。 すなわち、 低用量のジンセノサイ ド R b iの静脈内持続投与の効果 ·効能 '用途について、 本 発明で詳細に説明された事項は、 ほぼすベてジンセノサイ ド R b iの病変部局所投 与や病変部外用投与にもあてはまると言える。 すなわち、 低濃度のジンセノサイ ド類特にジンセノサイ ド R b の皮膚外用塗布が、 皮膚の表皮組織、 真皮の結合組 織、 真皮の乳頭、 血管、 皮脂腺、 神経、 汗腺、 毛乳頭、 立毛筋、 毛包等の再生 · 再構築を促進し、 創傷治療を早めると考えられる。 本発明者の知る限り、 低濃度 のジンセノサイ ド R b tの皮膚外用投与の効果は、 ペプチド性因子 (P D G F、 E G F、 b F G F ) の効果よりはるかに優れている。 本実験で使用した低濃度のジ ンセノサイ ド R b iを含有する軟膏もしくは外用剤は、 皮膚のみならず損傷もしく は、 病理組織学的変化をきたすあらゆる臓器 ·組織 (角膜、 口腔、 外耳、 鼓膜、 膣、 子宮、 尿道、 直腸、 肛門等) に外用投与して、 病変組織の再生 ·再構築を促 進せしめることができる。 本実験結果より、 プロぺト 1 0 gあたりのジンセノサ イ ド類特にはジンセノサイ ド R b の混入量は 0 . 1 m g以下、 好ましくは 0 . 0 0 0 1 m g以下ということが判明した。 すなわち皮膚疾患を有するヒトもしくは 脊椎動物へのジンセノサイ ド類特にはジンセノサイ ド R b の皮膚外用投与量は、 患者の個人差や病状にもよるが、 従来考えられていたよりはるかに少ないという ことになる。 本実験では高濃度のジンセノサイ ド R b i ( 0 . 0 0 0 1重量%以 上) の効果は動物によりばらつきがみられた。 ラッ トでは 0 . 0 0 1重量%— 0 . 0 0 0 1重量%という高濃度のジンセノサイ ド R b iを開放創に外用投与しても、 しばしば同動物は開放創をなめることがあるので、 その結果として開放創部のジ ンセノサイ ド R b の濃度が低下して時折好ましい効果が得られたと考えられる。 しかし、 ヒトでは開放創をなめるという行為はほとんど起こり得ないので、 創傷 治癒促進のためにはより低濃度 (たとえば 0 . 0 0 0 0 2重量%未満) のジンセ ノサイ ド R b iを外用投与することが好ましい。 Moreover, as shown from the top of the first 0 view to the second and third, 0.0 0 0 0 1 wt% (1 0 5 wt%) or 0.0 0 0 0 0 1 wt% (1 0 ( 6 % by weight) ginsenoside Rbi showed a better effect than the one containing 0.0001% by weight ginsenoside Rbi. This means that low concentrations of ginseno Topical skin application consisting of side R bi is applied or sprayed on open wounds, and it has been shown that the same effect and efficacy as low-dose continuous intravenous ginsenoside R b can be obtained. . In addition, when the ginsenoside Rb was added to the skin in an amount of 0.000001% by weight, the hair growth was clearly observed from the regenerated open wound. In other words, the effects and efficacy of low-dose ginsenoside R bi by continuous intravenous administration. It can be said that this also applies to topical administration. In other words, topical application of low-concentration ginsenosides, especially ginsenoside Rb, to the skin can lead to epidermal tissue of the skin, connective tissue of the dermis, papillae of the dermis, blood vessels, sebaceous glands, nerves, sweat glands, dermal papilla, pilo muscularis, hair follicles It is thought that it will promote regeneration and reconstruction of the wound, etc., and hasten wound treatment. To the inventor's knowledge, the effect of the skin external administration of low concentrations of Jinsenosai de R b t is far superior effect of the peptide factors (PDGF, EGF, b FGF) . The ointment or topical preparation containing a low concentration of ginsenoside Rbi used in this experiment may be used not only on the skin but also on any organ or tissue that causes damage or histopathological changes (cornea, oral cavity, outer ear, eardrum) Topical administration to the vagina, uterus, urethra, rectum, anus, etc.) to promote the regeneration and reconstruction of diseased tissue. From the results of this experiment, it was found that the amount of ginsenosides, especially ginsenoside Rb, per 10 g of the product was 0.1 mg or less, and preferably 0.001 mg or less. In other words, the topical dose of ginsenosides, especially ginsenoside Rb, to humans or vertebrates with skin diseases is much lower than previously thought, depending on individual differences and medical conditions of patients. . In this experiment, the effects of high concentrations of ginsenoside R bi (above 0.0001% by weight) varied among animals. In rats, even if the ginsenoside R bi at a high concentration of 0.001% by weight—0.0001% by weight is applied externally to the open wound, the animal often licks the open wound. As a result, it is considered that the concentration of ginsenoside R b in the open wound decreased, and a favorable effect was sometimes obtained. However, since the act of licking open wounds is unlikely in humans, a lower concentration (for example, less than 0.0002% by weight) of ginsenoside Rbi is topically administered to promote wound healing. Is preferred.
前述のごとく、 低濃度のジンセノサイ ド R b tの皮膚外用塗布が、 皮膚の表皮組
織、 真皮の結合組織、 真皮の乳頭、 皮下組織、 血管、 立毛筋、 皮脂腺、 汗腺、 毛 乳頭、 毛包等の再生 ·再構築を促進するという事実は、 当然のことながらジンセ ノサイ ド R b iの皮膚外用塗布が、 表皮細胞、 表皮角化細胞 (ケラチノサイ ト) 、 メルケル細胞、 メラノサイト、 ランゲルハンス細胞、 角質細胞、 真皮ならびに皮 下組織の線維芽細胞、 血管内皮細胞、 血管平滑筋細胞、 皮脂腺の細胞、 脂肪細胞、 汗腺の細胞、 毛包の細胞、 立毛筋の細胞、 間葉系細胞、 皮膚の幹細胞等の再生 - 再構築をも促すことを明らかにしている。 すなわち、 ジンセノサイド R b などの ジンセノサイ ド類は皮膚組織を構成するあらゆる細胞やその分泌物の再生 ·再構 築を促進すると考えられる。 一方、 加齢に伴う皮膚の諸症状 (皮膚の萎縮、 易感 染性、 たるみ、 かゆみ、 かさつき、 亀裂、 皮脂欠乏、 角質細胞剥離、 角層剥離、 ひびわれ、 あかぎれ、 しみ、 しわ、 そばかす、 脱毛、 白髪、 ふけ、 色素沈着、 日 焼け、 乾燥等) は、 皮膚組織を構成する前記細胞が、 紫外線障害や生体の老化に 伴い徐々に死滅するかもしくは機能不全に陥り、 もとの健常な状態に再生できな くなるために、 生じるものと考えられる。 たとえば、 加齢や老化に伴う皮膚のか さっき、 乾燥、 脱毛、 亀裂、 角質細胞剥離、 角層剥離、 ひびわれ、 あかぎれ、 皮 脂欠乏、 かゆみなどは皮膚の汗腺、 毛包、 ならびに脂腺の細胞が、 機能障害に陥 るか死滅したままで再生しないために、 生じると考えられる。 また、 日焼け、 色 素沈着、 しみ、 そばかす等は、 日光や紫外線に照射された皮膚の細胞が死に至つ ても、 元通りに細胞が再生しなくなるために起こると考えられる。 さらに加齢に 伴う、 皮膚のしわ、 たるみ、 萎縮などは、 真皮や皮下組織の線維芽細胞もしくは 間葉系細胞が、 加齢とともに機能不全に陥るか数が減少したために、 真皮や皮下 組織で充分な膠原線維、 弾性線維、 細網線維、 細胞外基質を保持できなくなった 結果、 生じると言える。 一方、 メラノサイ トやランゲルハンス細胞の機能障害に より白髪や易感染性が生じると考えられる。 As mentioned above, topical application of low-concentration ginsenoside R bt to the skin epidermis Naturally, the fact that it promotes the regeneration and remodeling of tissue, connective tissue of the dermis, papillae of the dermis, subcutaneous tissue, blood vessels, pilates, sebaceous glands, sweat glands, hair nipples, hair follicles, etc. Skin application for epidermal cells, epidermal keratinocytes (keratinocytes), Merkel cells, melanocytes, Langerhans cells, keratinocytes, dermal and subdermal tissue fibroblasts, vascular endothelial cells, vascular smooth muscle cells, sebaceous glands It has also been shown to promote the regeneration and remodeling of cells, fat cells, cells of sweat glands, cells of hair follicles, cells of the pilo-ermis, mesenchymal cells, and stem cells of the skin. In other words, ginsenosides such as ginsenoside Rb are considered to promote the regeneration and reconstitution of all cells and their secretions constituting skin tissue. On the other hand, various skin symptoms associated with aging (skin atrophy, susceptibility, sagging, itching, bulkiness, cracks, sebum deficiency, keratinocyte exfoliation, horny layer exfoliation, cracks, irritations, spots, wrinkles, freckles, Hair loss, gray hair, dandruff, pigmentation, sunburn, dryness, etc.) are due to the fact that the cells constituting the skin tissue gradually die or become dysfunctional due to ultraviolet damage or aging of the living body. It is thought to be caused by the inability to reproduce in a state. For example, skin aging, aging, aging, depilation, cracking, keratinocyte detachment, horny layer detachment, cracks, dermis, sebum deficiency, and itching are caused by the cells of the sweat glands, hair follicles, and sebaceous glands of the skin. It is thought to be caused by dysfunction or death and not regenerating. In addition, sunburn, pigmentation, spots, freckles, etc. are thought to occur because even if skin cells exposed to sunlight or ultraviolet light die, they will not regenerate as before. In addition, wrinkles, sagging, atrophy, etc. of the skin associated with aging may be caused by fibroblasts or mesenchymal cells in the dermis or subcutaneous tissue that become dysfunctional or decrease in number with age, This can be attributed to the inability to retain sufficient collagen, elastic, reticulum, and extracellular matrix. On the other hand, dysfunction of melanocytes and Langerhans cells may cause gray hair and susceptibility.

Furthermore, ginsenoside R bi is a brain cell or neuronal cell protecting agent comprising ginsenoside R bi, which has been filed by the present inventors (Osakanaka, Tanaka) (WO 00/37848). CT / JP 00/041002, a ginseng-containing brain cell or neuronal cell protective agent) that enhances the expression of the cell death suppressor gene product Be1—, resulting in epidermal cells and keratinocytes. , Keratinocytes, sebaceous gland cells, hair follicle cells, pilo muscular cells, sweat gland cells, fibroblasts, stem cells, mesenchymal cells, vascular endothelial cells, vascular smooth muscle cells, fat cells, etc. Since it is thought to protect all skin cells, it is also possible to prevent the death or dysfunction of skin constituent cells due to aging and aging. Thus, ginsenosides, such as ginsenoside Rb, not only protect all the cells that make up the skin, but also regenerate those cells once the skin cells die or fail. Age-related skin aging symptoms (skin atrophy, susceptibility to infection, sagging, itching, fissures, keratosis, sebum deficiency, exfoliation of keratinocytes, stratum corneum, cracks, irritations, spots, wrinkles, freckles, gray hair Dandruff, hair loss, pigmentation, sunburn, poor reproduction, dryness, etc.). In other words, it can be said that ginsenosides, especially ginsenoside Rb, improve, prevent or alleviate the aging symptoms of skin with aging through two powerful actions of cytoprotective action and tissue / cell regeneration promoting action. Furthermore, as is clear from the experimental results of the present invention and the above-mentioned patents (WO 00/37848, WO 00/46808), ginsenosides, in particular, ginsenoside R b is a cytoprotective and cytoprotective effect when the extracellular fluid concentration in the affected tissue or skin tissue is lng / ml or less, preferably 10 pg / m1 or less, more preferably 100 fg / m1 or less. Tissue ・ Produces cell regeneration promoting action. In addition, as described in Examples described later, low-concentration / low-dose ginsenosides, particularly ginsenoside Rbt, can also promote regeneration and reconstruction of mucosal tissues, and can treat bites on oral mucosa. Accordingly, ginsenosides, especially natural products containing ginsenoside Rbt or ginsenoside Rbi or extracts thereof, may be used for any cosmetics and health products (such as lotions (skin lotions), emulsions (milk lotions), serums, massage agents, Packs, emulsions, foundations, creams, gels, lotions, emulsions, powders, Hair dye, hair manicure, cold cream, eye shadow, cleansing cream, facial cleansing foam, night cream, whitening cream, troche, throat, whitening, lipstick, bath salt, toilet soap, healthy drinking water, isotonic war Tar, water splitting ice, sherbet, ice cream, alcoholic beverages, eyewash, eyewash, face wash, mouthwash, shampoo, rinse, toothpaste, lip balm, base cream (makeup base), UV liquid Base, powder foundation, etc.) and maintain the extracellular solution concentration of ginsenosides, especially ginsenoside R bi at the local skin or mucous membrane at a low concentration as described above. Aging symptoms (atrophy, susceptibility, sagging Itching, fissure, dryness, poor regeneration, epithelial detachment, mucosal detachment, sebum deficiency, keratinocyte detachment, stratum corneum detachment, cracks, irritations, spots, wrinkles, freckles, gray hair, dandruff, hair loss, pigmentation, tanning, It has an excellent effect on drying. For example, with the aging and aging of the skin, the deficiency of skin fats (ie, sebum) alone can cause the skin to become bulky, cracked, dry, itchy, exfoliate keratinocytes, etc., but low concentrations of ginsenosides, especially ginsenosides By mixing Rb or ginsenoside Rb-containing natural product or its extract in any cosmetics, the protection, regeneration and reconstruction of the sebaceous glands is promoted, and the aforementioned aging symptoms of the skin associated with aging are prevented. , Improvement, or alleviation. In addition, any cosmetic containing a low concentration of ginsenosides, especially ginsenoside Rbi, not only protects epidermal cells (keratinocytes) or epidermal keratinocytes, but also promotes their regeneration. It also promotes the production and secretion of lipids and natural moisturizing factors, thereby preventing the skin from drying and swelling, and providing the skin with natural moisture. Ginsenosides, especially ginsenoside Rb, natural product extract containing ginsenoside Rb, crude ginseng crude saponin fraction, etc. are mixed at low concentration into mineral water, etc. Can improve, prevent, and treat disorders of the oral mucosa and gastrointestinal mucosa (especially the esophageal mucosa). Ginsenosides at low concentrations, especially natural product extracts containing ginsenoside Rb or ginsenoside Rb, are used as chemical peeling compositions in the entire process (before, during or after) chemical peeling. Or one or more of the excipients (ie, chemical peeling agents) Can be used. Of course, as described above, instead of ginsenoside R b, a natural product containing ginsenoside R bi, a natural product extract, ginseng, a ginseng extract, a crude ginseng crude saponin fraction, etc., for an external skin composition (Cosmetic composition, hair growth composition, composition for chemical peeling). In addition, the cosmetic composition of the present invention, a composition for hair growth and hair growth, a composition for chemical peeling (natural products containing ginsenoside R bi or extracts thereof, ginseng, ginseng extract, ginseng crude Bases of saponin fraction, ginsenosides, ginsenoside derivatives) include oils and fats, waxes, hydrocarbons, fatty acids, lower alcohols, higher alcohols, polyhydric alcohols, and esters. , A surfactant, and a water-soluble polymer compound. The composition for external use on the skin (cosmetic composition, composition for hair growth and hair growth, composition for chemical peeling) of the present invention includes other skin cell activators, hair growth and hair growth compositions, cosmetic compositions, anti-inflammatory agents, Active oxygen scavenger, whitening agent, humectant, UV absorber, antiseptic / antifungal agent, vitamins, minoxidil, emollient, known natural product extract, known crude drug extract, known natural product component, retinoic acid ac id) may be used in combination with one or more of them. The above-mentioned known natural product extract or natural component includes, but is not limited to, any crude drug, crude drug extract or crude drug component used in Chinese herbal prescriptions. When ginsenoside Rb is used almost alone as an external preparation for skin, an external preparation for mucous membrane, or an external composition for skin, its concentration should be less than 0.001% by weight, and other pharmaceutical compositions or external compositions for skin. When used together, the concentration is preferably less than 0.002% by weight. The upper limit of the concentration of the natural product containing ginsenoside R bi or its extract is considered to be less than 0.001% by weight. When a ginsenoside derivative such as dihydroxyzine senoside Rb or epoxy ginsenoside Rb is used as the above-mentioned external preparation or external composition, the concentration is 0.001% by weight or less, preferably less than 0.01% by weight. It is less than 0.0000% by weight. The upper limit of their concentration is 3% by weight, preferably 0.1% by weight or less.
次に本発明者の一人 (阪中) は低濃度のジンセノサイ ド R b iを含有するプロぺ 卜が口腔粘膜の咬傷に有効であるかどうか、 自身で確認した。 平成 1 2年 5月 2 日午後 2時頃に阪中は歯科治療後左三叉神経第三枝の浸潤麻酔ならびに歯根膜麻
酔が醒める前に、 空腹のあまり遅い昼食をとり始めた。 1 5分以内に自身の左下 唇粘膜を 3度嚙んでしまい、 その後口腔内に鉄の味覚 (血液) を感知したので、 鏡にて咬傷を確認した所、 少なくとも 5ケ所に口腔粘膜のびらんもしくは欠損を 認め、 さらに 1ケ所に血腫を認めた。 このまま、 放置すると数日以内にァフタ性 口内炎を併発し、 完治までに 1週間から 1 0 日を要すると判断したので、 本発明 者らの動物実験で効果 ·効能が確認されている低濃度 (0 . 0 0 0 0 1重量%) のジンセノサイ ド R b iを含有したプロぺトを、 口腔粘膜咬傷部のびらんもしくは 欠損をきたした領域 5ケ所、 ならびに血腫の部位 1ケ所に少量外用塗布した。 外 用塗布は、 毎食前後ならびに間食前後に実施した。 なお、 食後にはできるかぎり 歯を磨いてから外用塗布することにした。 すなわち 1 日 6 — 1 0回に分けて咬傷 部位に 0 . 0 0 0 0 1重量%のジンセノサイ ド R b iを含有するプロべトを口唇粘 膜へ外用塗布した。 咬傷後 9 6時間目の口唇粘膜の写真を第 1 1図に示す。 第 1 1図は図面に代わる写真である。 Next, one of the present inventors (Sakanaka) himself confirmed whether or not the project containing a low concentration of ginsenoside Rbi was effective for biting the oral mucosa. Around 2:00 pm on May 2, 2002, Osaka was treated with dental anesthesia and infiltration of the third trigeminal nerve after periodontal treatment. Before drunkenness, he began to have a hungry, too late lunch. Within 15 minutes, he left his lower lip mucous membrane three times, and then sensed the taste (blood) of iron in the oral cavity. Defect was observed, and hematoma was observed in one more place. If left untouched, aphthous stomatitis would occur within a few days, and it was determined that it would take 1 week to 10 days for complete cure. Therefore, the low concentration ( (0.00001% by weight) of ginsenoside Rbi was applied topically in small amounts to 5 sites of erosion or defect of the oral mucosa bite and 1 site of hematoma. External application was performed before and after each meal and before and after a snack. After the meal, we decided to brush the teeth as much as possible before applying topically. That is, a probe containing 0.00001% by weight of ginsenoside Rbi was externally applied to the lip mucosa at the bite site in 6 to 10 times a day. A photograph of the lip mucosa 96 hours after the bite is shown in FIG. Figure 11 is a photograph replacing a drawing.
第 1 1図の写真に示すごとく、 咬傷後 9 6時間目には白矢頭で示すごとく血腫 は残っているが、 その他の黒矢頭で示した口唇粘膜の咬傷部 (すなわちびらんも しくは欠損をきたした口腔粘膜) は、 わずかに発赤がみられるのみでほぼ完全に 上皮化が進んでおり、 明らかに創傷が治癒したと考えられた。 なお、 0 . 0 0 0 0 1重量%のジンセノサイ ド R b iを含有するプロべトを咬傷部に外用塗布し始め てからは、 創部における疼痛も顕著に軽減した。 おそらく低濃度のジンセノサイ ド R b の口腔粘膜外用投与により、 咬傷により切断した末梢神経が上皮化ととも に速やかに再生したため、 疼痛が軽減したと考えられる。 本発明者の経験では、 このような咬傷が治癒するのには、 少なくとも 7 日から 1 0日はかかるが、 低濃 度のジンセノサイ ド R b!外用投与により明らかに口唇粘膜組織が速やかに再生 - 再構築し、 9 6時間以内に咬傷 (創傷) 治癒が著しく促進されたと言える。 しか も、 咬傷後にァフタ性口内炎を併発することもまったくなかった。 おそらく、 粘 膜病変に対しては、 ジンセノサイ ド類特にはジンセノサイ ド R b を含有する外用 剤を 1 日に 1 一 1 0回病変部に局所投与すれば効果がみられると考えられる。 一般にァフタ性口内炎にはデキサルチン軟膏のようなステロイド剤が臨床現場 でよく使用されるが、 周知のごとくステロイ ド剤はァフタ性口内炎の疼痛を軽減
するものの、 創傷や組織の欠損部位の治癒を遅らしむるという副作用を示す。 し かも、 雑菌が多く存在する口腔内の粘膜病変に対して免疫機能抑制作用を有する ステロイ ド剤を外用塗布することは感染症の併発を考慮すると必ずしも好ましい とは言えない。 As shown in the photograph of Fig. 11, at 96 hours after the bite, a hematoma remains as indicated by a white arrowhead, but the bite of the labial mucosa indicated by a black arrowhead (that is, erosion or defect is not observed). The epithelium of the oral mucosa was slightly reddened, and the epithelization was almost complete. It was considered that the wound had clearly healed. After external application of a probe containing 0.0001% by weight of ginsenoside Rbi to the bite site, pain at the wound site was remarkably reduced. Presumably, the oral administration of ginsenoside Rb at a low concentration to the oral mucosa relieved pain because the peripheral nerve cut by the bite rapidly regenerated with epithelialization. In the inventor's experience, healing such a bite takes at least 7 to 10 days, but low concentrations of ginsenoside R b! It can be said that the topical administration clearly regenerated and reconstructed the labial mucosal tissue rapidly, and the healing of the bite (wound) was significantly accelerated within 96 hours. No bitter stomatitis occurred after the bite. Presumably, topical administration of ginsenosides, especially ginsenoside Rb, to the lesions 11 to 10 times a day is considered to be effective for mucosal lesions. In general, steroids such as dexartin ointment are often used in clinical settings for aphthous stomatitis, but as is well known, steroids reduce the pain of aphthous stomatitis. However, it has the side effect of slowing the healing of wounds and tissue defects. However, it is not always preferable to apply a topical steroid agent, which has an immune function-suppressing effect, on mucosal lesions in the oral cavity, where many germs are present, in view of concurrent infection.
—方、 低濃度のジンセノサイ ド R b iの粘膜外用投与は創 «治癒や上皮化を促進 せしめ、 かつ粘膜病変における末梢神経の再生も促進させるので、 ステロイ ド剤 の粘膜外用投与よりも優れた治療法と考えられる。 しかも、 低濃度のジンセノサ イ ド R b iは免疫機能抑制作用も示さないので、 極めて安全な医薬組成物と言える c 今後、 ァフタ性口内炎の第一選択薬としても低濃度ジンセノサイド R b は利用で きると期待される。 もちろん、 ジンセノサイ ド R b などのジンセノサイ ド類をァ フタツチゃパップ剤のような剤型として用いてもよい。 On the other hand, external administration of low-concentration ginsenoside Rbi to the mucosa promotes wound healing and epithelialization and promotes regeneration of peripheral nerves in mucosal lesions. It is considered a law. In addition, low-concentration ginsenoside R bi does not show an immune function-suppressing effect, so it can be said that it is an extremely safe pharmaceutical composition.c It is expected that low-concentration ginsenoside R b can be used as a first-line drug for aphthous stomatitis in the future Be expected. Of course, ginsenosides such as ginsenoside Rb may be used as a dosage form such as an aphthatic patch.
次に本発明者の一人 (阪中) は、 平成 1 2年 5月 2 6 日昼食中に再度左下唇粘 膜を嚙んでしまったので、 0 . 0 0 0 0 1重量%のジンセノサイ ド R b iを含有す るプロぺトを同様の方法で咬傷部へ外用塗布した。 咬傷直後の写真を第 1 2図の 左側に、 咬傷後 7 2時間目の写真を第 1 2図の右側に示す。 第 1 2図は図面に代 わる写真である。 Next, one of the present inventors (Sakanaka) re-opened the left lower lip mucous membrane during lunch on May 26, 2012, so that 0.001% by weight of ginsenoside R was used. The plot containing bi was applied externally to the bite site in the same manner. The photograph immediately after the bite is shown on the left side of FIG. 12, and the photograph 72 hours after the bite is shown on the right side of FIG. Figure 12 is a photograph replacing the drawing.
第 1 2図に示すごとく、 低濃度のジンセノサイ ド R b を粘膜へ外用投与すれば、 ァフタ性口内炎を併発することなく咬傷が速やかに治癒することが判明した。 従 つて低濃度のジンセノサイ ド R b tは、 皮膚組織のみならずヒトロ腔粘膜を始めと する粘膜組織の再生 ·再構築をも促進し、 創傷治癒を速やかに進めるものと考え らえる。 このような事実にもとづけば、 低濃度のジンセノサイ ド類特にジンセノ サイ ド R b iは口腔粘膜を含む粘膜や口腔内組織の病理組織学的変化をきたすあら ゆる疾患や病態に対しても、 組織再生 ·再構築促進作用を介して効果 ·効能を発 揮すると言える。 このような疾患として、 う蝕、 歯髄炎、 辺縁性歯周組織炎、 口 内炎、 舌炎、 再発性ァフタ、 口腔内ァフタ、 口臭、 口腔異常感症、 歯性感染症、 口腔粘膜咬傷、 舌の咬傷、 口腔粘膜熱傷、 舌の熱傷、 口腔粘膜損傷、 歯肉炎、 歯 槽膿漏、 カタ一ル性口内炎、 壊疽性口内炎、 ワンサン口内炎、 ァフタ性口内炎、 急性疱疹性歯肉口内炎、 ヘルパンギーナ、 帯状疱疹、 口腔粘膜びらん、 口腔粘膜 潰瘍、 褥瘡性潰癟、 放射線性口内炎、 天疱瘡、 口腔カンジダ症、 扁平苔癖、 R i

Therefore, the low concentration of ginsenoside Rbt promotes the regeneration and reconstruction of not only skin tissue but also mucosal tissue including the human mucosal mucosa, and is thought to accelerate wound healing. Based on these facts, low concentrations of ginsenosides, especially ginsenoside Rbi, are effective against all diseases and conditions that cause histopathological changes in mucous membranes including oral mucosa and oral tissues.

External preparations containing low concentrations of ginsenosides, especially ginsenoside Rb, are used not only for oral mucosa but also for gastrointestinal mucosa, nasal mucosa, ocular mucosa (conjunctiva, cornea), vaginal mucosa, uterine mucosa, urethra When applied externally to all mucous membranes, such as mucosa, bladder mucosa, trachea and bronchial mucosa, it is highly effective against diseases and conditions that cause histopathological changes in these mucous membranes. In particular, topical administration of ginsenosides, especially ginsenoside Rbi, is effective for mucosal wounds, burns, inflammation, erosions, ulcers, defects, hay fever and spring catarrh. Furthermore, topical mucosal preparations containing low concentrations of ginsenosides, especially ginsenoside Rb, prevent and improve mucosal aging symptoms (atrophy, epithelial detachment, mucosal detachment, poor regeneration, cracks, dryness, etc.) It can also be used as a health drug for treatment. The effects, indications, and uses of ginsenoside R bi described so far are the effects and indications of ginsenoside derivatives such as dihydroxy ginsenoside R b epoxy ginsenoside R b or dihydroxy ginsenoside R bi. · It can be said that it is common to all applications. The action of dihydrozincenoside Rb: to promote skin wound healing will be described later. However, judging from the results of the culture experiment, ginsenoside derivatives It is considered that it can be used in a wider concentration range than Side Rb. Specifically, it is considered that an effective dose / concentration can be set within a range of about 1/1000 to 1000 times the administered dose / concentration of ginsenoside Rbi.
次に本発明者らは、 ジンセノサイ ド類特にジンセノサイ ド R b iが皮膚組織や口 腔粘膜組織のみならず、 植物組織の新生 ·再生もしくは再構築をも促進するかど うかを調べた。 このため植物組織として観葉植物の 1つであるポトスを選んだ。 発明者の一人 (田中) の部屋にあるポトスの親株から、 類似した挿し木を 6本採 取し、 3本は水のみを用いて水栽培し、 残り 3本は 1 0 0 f g / m 1 のジンセノ サイ ド R b iを含有する水中で栽培した。 栽培 1 3 日目の挿し木の写真を第 1 3図 に示す。 第 1 3図は図面に代わる写真である。 Next, the present inventors investigated whether ginsenosides, especially ginsenoside Rbi, promotes the regeneration, regeneration, or reconstruction of plant tissues as well as skin tissues and oral mucosal tissues. For this reason, pothos, one of the foliage plants, was selected as the plant tissue. Six similar cuttings were taken from the parent plant of Potos in one of the inventor's (Tanaka) rooms, three were hydroponically grown using only water, and the remaining three were 100 fg / m1 ginseno. Cultivated in water containing side R bi. Fig. 13 shows photographs of cuttings on the 13th day of cultivation. Figure 13 is a photograph replacing the drawing.
第 1 3図の左側は水のみで挿し木 (ポトスの茎と枝) を水栽培したものであり、 第 1 3図の右側は、 低濃度のジンセノサイ ド R b i ( 1 0 0 f g / m 1 ) を含有す る水で挿し木を水栽培したものである。 明らかに低濃度のジンセノサイ ド R b The left side of Fig. 13 shows the hydroponics of cuttings (pothos stems and branches) with water only, and the right side of Fig. 13 shows the low concentration of ginsenoside R bi (100 fg / m 1). Cuttings were hydroponically grown with the contained water. Clearly low ginsenoside R b
( 1 0 0 f g / m 1 ) を含有する水で、 ポトスの挿し木を水栽培した場合に根の 伸長が促進された。 (100 fg / m1) promoted root elongation when potato cuttings were cultivated in water.
次に、 本発明者らは、 前述の挿し木を引き続き水栽培に供し、 2 2 日目に再度 写真撮影を実施した。 結果を第 1 4図に示す。 第 1 4図は図面に変わる写真であ る。 第 1 4図の左側は、 水のみでポトスの挿し木を 3本 2 2 日間水栽培したもの であり、 第 1 4図の右側は、 低濃度のジンセノサイ ド R b i ( 1 0 0 f g / m 1 ) を含有する水で挿し木を水栽培したものである。 なお、 水栽培用の水もしくはジ ンセノサイ ド R b を含有する水は、 1週間ごとに一度交換した。 さらに、 本発明 者らは 2 7 日目にも発根部位を観察した。 Next, the present inventors continued the hydroponic cultivation of the cuttings described above, and again photographed them on the 22nd day. The results are shown in FIG. Fig. 14 is a photograph that changes to a drawing. The left side of Fig. 14 shows three pothos cuttings cultivated with water alone for 22 days, and the right side of Fig. 14 shows low concentration of ginsenoside R bi (100 fg / m 1). Cuttings were cultivated with water containing water. Water for hydroponics or water containing ginsenoside R b was replaced once a week. Furthermore, the present inventors also observed the rooting site on the 27th day.
第 1 4図に示すごとく、 低濃度のジンセノサイ ド R b i ( 1 0 0 f g / m 1 ) を 含有する水で挿し木を 2 2 日間水栽培すると、 水のみで水栽培されたポトスと比 ベて、 より多くの根が新生もしくは再生し、 水栽培用ガラス容器に接するまでに 伸長した。 さらに、 2 7 日目になると、 低濃度のジンセノサイ ド R b i ( 1 0 0 f g / m 1 ) を含有する水で栽培されたポトスの挿し木 3本すべてに、 一次発根部 位より明らかな二次発根が観察された。 しかし、 水のみで栽培されたポトスの揷 し木 3本には、 まったく二次発根は認められなかった。 従って、 本実験結果より
低濃度 ·低用量のジンセノサイ ド類特にはジンセノサイ ド R b iもしくはジンセノ サイ ド R b iを含有する天然物又はそのエキスは皮膚組織ゃヒ ト口腔粘膜組織のみ ならず、 植物組織の発根,発芽 ·成長 ·分化 ·新生 ·再生もしぐは再構築をも促 進することが明らかにされた。 As shown in Fig. 14, when cuttings were cultivated for 22 days in water containing low concentration of ginsenoside R bi (100 fg / m 1), compared to pothos hydroponically cultivated with water alone, Many roots regenerated or regenerated and grew before contacting the hydroponic glass containers. Furthermore, on day 27, all three cuttings of pothos grown in water containing low concentrations of ginsenoside R bi (100 fg / m 1) showed secondary Rooting was observed. However, no secondary rooting was observed in any of the three young pothos grown on water alone. Therefore, from the results of this experiment Low-concentration and low-dose ginsenosides, especially ginsenoside R bi or natural products containing ginsenoside R bi or extracts thereof, include not only skin tissues, human oral mucosa tissues, but also rooting and germination of plant tissues. It was revealed that growth, differentiation, new generation, regeneration, and regeneration also promote restructuring.
すなわちジンセノサイ ド R b iなどのジンセノサイ ド類は、 あらゆる生体組織 (動物 ·植物組織) の再生 ·新生 ·再構築を促進すると言える。 In other words, ginsenosides such as ginsenoside Rbi promote the regeneration, renewal, and reconstruction of all living tissues (animal and plant tissues).
前記の実験で示したごとく、 1 0 0 i g / m lのジンセノサイド R b iを含有す る水溶液中で、 植物組織たとえばポトスの挿し木を栽培すると、 対照の挿し木に 比べて明らかに根の新生が促進される。 従って前述のごとく、 ジンセノサイ ド R b 丄などのジンセノサイ ド類は、 動物組織のみならず、 成長調整用組成物として植 物組織の発根 ·発芽 ·成長 ·分化 ·新生 ·再生もしくは再構築をも促進すると言 える。 As shown in the above experiments, cultivation of plant tissues, such as pothos cuttings, in an aqueous solution containing 100 ig / ml ginsenoside Rbi clearly promotes root regeneration compared to control cuttings. You. Therefore, as described above, ginsenosides such as ginsenoside R b と し て can be used not only in animal tissues, but also as a composition for regulating growth in the rooting, germination, growth, differentiation, renewal, regeneration or regeneration of plant tissues. It can be said to promote.
しかも、 植物組織の発根 ·発芽 · 成長 ·分化 ·新生 ·再生もしくは再構築を促 進させるジンセノサイ ド R b tの細胞外液濃度は、 動物組織 (皮膚組織、 口腔粘膜 組織) を再生 ·再構築させる場合と同様に、 極めて低いことが本発明において見 出された。 従って、 ジンセノサイ ド R b などのジンセノサイ ド類は、 植物の栽培 -育成 ·保存、 生花の保存 ·栽培 ·育成、 水栽培、 水耕栽培、 農作物栽培 ·育成、 野菜の栽培 '育成、 果実 (フル一ッ) の栽培 ·育成、 たばこの栽培 ·育成、 きの こ栽培、 薬用植物栽培、 茶葉の栽培,育成等に利用できると言える。 ジンセノサ ィ ド R b などのジンセノサイ ド類もしくはジンセノサイ ド R b tを含有する天然 物又はそのエキスからなる発根 ·発芽 · 成長 ·分化促進剤もしくは肥料組成物は、 任意の肥料に好ましくは低濃度 ( 1重量%以下、 好ましくは 0 . 1重量%以下、 より好ましくは 0 . 0 0 1重量%以下) で混入又は添加することができるが、 細 胞外液濃度を前述のごとく低く維持できるのであれば単独で植物組織の発根 ·発 芽 ·分化 ·再生 · 再構築 ·新生 ·成長促進剤として使用してもよい。 もちろん、 ジヒドロキシジンセノサイ ド R b h エポキシジンセノサイ ド R b 又はジヒドロ ジンセノサイ ド R b などのジンセノサイ ド類誘導体も、 ジンセノサイ ド R b と 同様に植物組織の発根 ·発芽 ·新生 ·成長 ·再生 ·分化もしくは再構築を促進し、 前述のような農産物、 植物、 野菜等の栽培 ·水栽培 · 育成 .保存のための植物成

Therefore, ginsenosides such as ginsenoside Rb are used for plant cultivation-cultivation and preservation, and preservation of fresh flowers. It can be said that it can be used for cultivation and cultivation, tobacco cultivation and cultivation, mushroom cultivation, medicinal plant cultivation, tea leaf cultivation and cultivation, etc. A rooting, germination, growth, differentiation promoting agent or fertilizer composition comprising a ginsenoside such as ginsenoside Rb or a ginsenoside Rbt-containing natural product or an extract thereof is preferably used in any fertilizer at a low concentration ( 1% by weight or less, preferably 0.1% by weight or less, more preferably 0.01% by weight or less), provided that the extracellular solution concentration can be kept low as described above. It may be used alone as rooting, germination, differentiation, regeneration, reconstruction, renewal, growth promotion of plant tissue. Of course, ginsenoside derivatives such as dihydroxy ginsenoside R bh epoxy ginsenoside R b and dihydro ginsenoside R b are also similar to ginsenoside R b, so that rooting, germination, new growth, growth, and regeneration of plant tissue are possible.・ Promote differentiation or reconstruction, and cultivate agricultural products, plants, vegetables, etc. It can be used as a composition for adjusting the length. Further, the composition for regulating plant growth of the present invention can also be used as a rooting promoter, a germination promoter, a flower preservative, and the like. Ginsenosides The fact that ginsenosides such as R bi promotes rooting, germination, differentiation, growth, renewal, regeneration or restructuring of plant tissues as well as animal tissues (skin tissues and oral mucosal tissues) It indicates that ginsenosides such as de R bi promote rooting, germination, differentiation, growth, new generation, regeneration or reconstruction of all living tissues. Therefore, it can be said that ginsenosides such as ginsenoside Rbi can also be used as a composition for livestock, aquaculture fish and shellfish, ornamental fish, and pet feed as shown in Example 23 described later. For example, when cultivating fish and shellfish such as locusts, crustaceans, eel, pearl oysters, pearl oysters, quells and burrows, low concentrations of ginsenosides, especially ginsenoside R bi or ginsenoside R bi are contained. The addition of natural products or extracts thereof to seawater or freshwater along with normal feed is thought to promote the development of these marine or marine resources. Of course, ginsenosides such as ginsenoside Rb or natural products containing ginsenoside Rbi are marine and marine resources such as fish and shellfish, crustaceans, eel, que, and eel through their cytoprotective action. Can be protected from trauma, wounds, pathogenic microorganisms, biohazard, endocrine disruptors, environmental pollution, toxins, etc. That is, the feed composition or the composition for regulating animal growth of the present invention is indispensable to rescue human beings from the coming food crisis. Of course, ginsenoside derivatives such as dihydroxy ginsenoside R bh epoxy ginsenoside R bi or dihydro ginsenoside R bi are also used as the above-mentioned fisheries products as ginsenoside R bt as a composition for controlling animal growth. It can be used to promote the growth of resources or marine resources. Ginsenosides such as ginsenoside R bi, natural products containing ginsenoside R bi, or dihydroxy ginsenoside R b epoxy ginsenoside R b! Or ginsenoside derivatives such as dihydroginsenoside R b, when used as a plant growth regulating composition, a fertilizer composition, a feed composition, or an animal growth regulating composition as described above. Their concentration in plant growth regulators, fertilizers, feed or animal growth regulators is 1% by weight or less, preferably 0.1% by weight or less, more preferably 0.01% by weight or less, even more preferably 0.01% by weight. It is preferably at most 1% by weight. Of course, the composition is ginsengosa As long as the concentration of extracellular fluids in the cells can be kept low, larger amounts can be used.
さて、 前述の口腔粘膜咬傷例において、 本発明者 (阪中) は 0. 0 0 0 0 1重 量% ( 1 0— 5重量%) のジンセノサイド R b を含有するプロべトを口腔粘膜 (下 唇粘膜) に 1 日 6— 1 0回外用塗布すると口腔粘膜組織が速やかに再生 ·再構築 し、 創傷が治癒しァフタ性口内炎も未然に防がれることを示した。 しかし、 当然 のことながら口腔粘膜咬傷部に 0. 0 0 0 0 1重量%のジンセノサイ ド R b を含 有するプロぺトを外用塗布しても、 唾液によって咬傷部近傍.のジンセノサイ ド R の細胞外液濃度は、 すぐに低くなつてしまうことが予想される。 おそらく、 0. 0 0 0 0 1重量%のジンセノサイ ド R b を含有するプロべトは、 口腔内の唾液に よって、 かなり希釈されても充分に口腔粘膜咬傷部組織の再生 ·再構築を促進す ると考えられる。 すなわち、 ジンセノサイ ド R t^は 0. 0 0 0 0 1重量%よりは るかに低い濃度域で効果 ·効能を発揮すると予想される。 従って、 皮膚の創傷部 にジンセノサイ ド R b を含有する外用剤を塗布するときは、 当該外用剤における ジンセノサイ ド R b iの濃度が唾液等で著しく希釈されることは考えにくいので、 0. 0 0 0 0 1重量%よりも低い濃度のジンセノサイ ド R b tを使用する方が好ま しいと考えられた。 そこで本発明者らは、 前述したラッ ト皮膚の開放創に、 さら に低い濃度のジンセノサイ ド Rb を含有するプロべトを外用塗布しその効果をし らベた。 Now, in the oral mucosa bites example above, the present inventors (Sakanaka) is 0.0 0 0 0 1 by weight% (1 0 5 wt%) ginsenoside R b which contained pro downy oral mucosa ( When applied topically 6-10 times a day to the lower lip mucosa), oral mucosal tissue was quickly regenerated and reconstructed, indicating that the wound was healed and that aphthous stomatitis could be prevented. However, as a matter of course, even if the oral mucosa bite is externally coated with a 0.001% by weight ginsenoside Rb-containing protrate, saliva causes ginsenoside R cells near the bite. It is expected that the concentration of the external solution will soon decrease. Possibly, a probe containing 0.001% by weight of ginsenoside R b promotes regeneration and reconstruction of oral mucosa bite tissue even when diluted significantly by oral saliva. It is considered to be. In other words, ginsenoside Rt ^ is expected to exhibit its effect and efficacy in a concentration range much lower than 0.001% by weight. Therefore, when an external preparation containing ginsenoside Rb is applied to the wound of the skin, it is unlikely that the concentration of ginsenoside Rbi in the external preparation is significantly diluted with saliva or the like. 0 0 1 prefer to use Jinsenosai de R b t of lower density than the weight% was considered preferable arbitrariness. Therefore, the present inventors applied topically a probe containing a lower concentration of ginsenoside Rb to the above-mentioned open wound of the rat skin, and examined the effect.
吸入麻酔下でラッ ト (n== 3) の背部に直径 6 mmのパンチバイオプシーを 6 ケ所に施し開放創を作成した。 その後、 各開放創に、 ジンセノサイ ド R b ,をそれ ぞれ 0. 0 0 0 1重量% ( 1 0— 4重量%) 、 0. 0 0 0 0 1重量% ( 1 0— 5重量 %) 、 0. 0 0 0 0 0 1重量% ( 1 0— 6重量%) 、 0. 0 0 0 0 0 0 1重量%Under inhalational anesthesia, 6-diameter punch biopsies were applied to the back of the rat (n == 3) at six locations to create open wounds. Thereafter, each open wounds, Jinsenosai de R b, a, respectively it 0.0 0 0 1 wt% (1 0 4% by weight), 0.0 0 0 0 1 wt% (1 0 5 wt%) , 0.0 0 0 0 0 1 wt% (1 0 6 wt%), 0.0 0 0 0 0 0 1 wt%
( 1 0— 7重量%) 、 0. 0 0 0 0 0 0 0 1重量% ( 1 0— 8重量%) の濃度で、 含 有するプロぺトを 1 日単回 0.

Each has traces of open wounds in six places of the right and left three increments, if the top of the left of the 0 one 4 wt%, in the case of 1 0 5 wt%, in the case of 1 0 6 wt%, right from 1 0 one 7 wt% on the, for a 1 0 8 wt% shows the case of 0% (control). Purobe bets (i.e. 1 0 ng / g 1 0 0 of pg / g concentration of Jinseno rhino containing the first 5 as shown in FIG. 1 0 -6 wt% 1 0 8 wt% Jinsenosai de R b Topical application of de-Rb to open wounds clearly promoted wound healing compared to open-wounds with topical application of only the protope, and topical application of low-concentration ginsenoside Rbi in a clear hair wound healing portion was observed. Thus, when the Jinse Nosai earth especially the use of Jinsenosai de R bi as a skin external preparation, its concentration in the external preparation 1 0 8% by weight before and after Therefore, ginsenosides, especially ginsenoside Rbi, should be used as a composition for hair growth and hair growth, a composition for chemical peeling, or a cosmetic composition. Sometimes the concentration is 0.0 0 less than 1 wt%, preferably 0.0 0 0 0 less than 2 wt%, more preferably 0.0 0 0 0 1 wt% (1 0 5% by weight) or less, more preferred properly 0. 0 0 0 0 0 0 0 1 wt% (1 0 8% by weight) it is necessary to set below. However, Jinsenosai de R bt a chemical peeling composition, mucosal topical composition or mucosal external preparation When used as a composition, the upper limit of the concentration may be set to 0.1% by weight.

Next, the present inventors have determined that the dihydroginsenoside R bi is the ginsenoside R b described in WO 00/37848, the dihydroxy ginsenoside R bi and the epoxy ginsenoside of the present invention. In order to confirm that it has the same effects, efficacy, and uses as Rbi, an experiment was further performed using cultured neurons.
既述のごとく本発明者 (阪中、 田中) らは、 培養神経細胞を一酸化窒素供与体 であるニトロプルシッ ドナトリウム (S N P ) に短時間暴露すると神経細胞のァ ポトーシスもしくはアポトーシス様神経細胞死が誘導されることを報告している (Toku K. et al., J. Neurosci. Res. , 53, 415-425, 1998) 。 この培養実験系 を用いて、 本発明者らはすでにジンセノサイ ド R b が 1 n g/m 1以下の細胞外 液濃度で、 より詳細には 1〜 1 0 0 f g/m 1 という至適細胞外濃度域で神経細 胞のアポト一シスもしくはアポトーシス様神経細胞死を抑止することを見出して いる (WO 0 0 / 3 7 4 8 1号、 P C T/ J P 9 9 / 0 2 5 5 0号、 ジンセノサ イ ド R b:からなる脳細胞又は神経細胞保護剤) 。 さらに、 同様の実験系において ジヒドロキシジンセノサイ ド R t 又はエポキシジンセノサイ ド R b も、 1 f g /m l 〜; L n g/m l又は 1 f g /m l〜 l 0 O n g /m l という至適細胞外液 濃度域で神経細胞のアポトーシスもしくはアポト一シス様神経細胞死を抑止する ことが本発明において見出されている。 そこで、 本発明者らは同様の実験系を用 いてジヒドロジンセノサイ ド R b ^の神経細胞保護作用をしらべた。 As described above, the present inventors (Sakanaka, Tanaka) and colleagues reported that short-term exposure of cultured neurons to the nitric oxide donor, nitroprusside sodium (SNP), resulted in neuronal apoptosis or apoptotic neuronal death. (Toku K. et al., J. Neurosci. Res., 53, 415-425, 1998). Using this culture experiment system, the present inventors have already determined that the ginsenoside Rb has an optimal extracellular solution concentration of 1 ng / m1 or less, more specifically 1 to 100 fg / m1. It has been found to inhibit apoptosis or apoptosis-like neuronal cell death in neural cells in the concentration range (WO 00/37 481, PCT / JP99 / 0 250 550, Ginsenosa Id Rb: a brain cell or nerve cell protecting agent). Furthermore, in the same experimental system, dihydroxy ginsenoside Rt or epoxy ginsenoside Rb also has an optimal cell content of 1 fg / ml to 1 ng / ml or 1 ng / ml to 10 ng / ml. It has been found in the present invention that apoptosis of nerve cells or apoptosis-like nerve cell death is inhibited in the external solution concentration range. Then, the present inventors examined the neuroprotective effect of dihydroginsenoside R b ^ using a similar experimental system.

After culturing for 16 hours in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal calf serum, the culture is cultured in neural cells containing insulin, transferrin, etc. The medium was replaced with a serum-free medium and cultured for 3 to 4 days. On the third or fourth day of culture, two-mouthed sodium prusid (SNP) was added at a concentration of 300 zM and incubated for 10 minutes. The culture was then replaced with Eagle's minimum essential medium (EMEM) containing dihydroginsenoside Rb (0-1 ng / ml) and bovine serum albumin. Sixteen hours after SNP loading, neurons were lysed using Laemmli electrophoresis sample buffer, and polyacrylamide gel electrophoresis was performed. After transfer of the substance to a nitrocellulose membrane, immu- noblotting was performed using an antibody against the neuronal cell-specific protein MAP2. To quantify neuronal cell viability, immunostained MAP2 bands were analyzed by densitometry. The results are shown in FIGS. 19 and 20. Figure 19 is a photograph replacing the drawing. In Fig. 20, n = 5, the * mark indicates a significant difference at P <0.001, and the ** mark indicates a significant difference at P <0.001. . The test is based on Scheife's post hoc test.

第 1 9図はマイクロチュブル関連蛋白 2 (microtuble- associated protein 2 (MA P 2 ) ) のィムノブロッ トの結果を示す図面に代わる写真である。 左から 1番目のレーンがコントロールの培養神経細胞であり、 明らかな MA P 2のバン ド (すなわち神経細胞のマ一力一のバンド) が認められた。 S N P処理をすると、 多くの神経細胞がアポトーシスもしくはアポトーシス様神経細胞死に陥るので、 M A P 2のバンドが左から 2番目のレーンのごとく明らかに弱くなつた。 ジヒド ロジンセノサイ ド R b を 0. 0 1 f g/m 1 (レーン 3 ) から 1 n g /m 1 (レ ーン 7 ) の濃度で培養メディウムに添加しておくと、 S N Pによる神経細胞のァ ポトーシス又はアポトーシス様神経細胞死が明らかに抑止され、 その結果神経細 胞の生存の指標である MA P 2の強いバンドが観察された。 FIG. 19 is a photograph in place of a drawing showing the results of the immunoblot of microtuble-associated protein 2 (MAP2). The first lane from the left is a control cultured neuron, in which a clear MAP2 band (ie, a band of neurons) was observed. The SNP treatment caused many neurons to undergo apoptosis or apoptotic neuronal death, so the MAP2 band was clearly weakened, as in the second lane from the left. If dihydro rosin senoside Rb is added to the culture medium at a concentration of 0.01 fg / m1 (lane 3) to 1 ng / m1 (lane 7), neuronal apoptosis by SNP or Apoptotic neuronal cell death was clearly suppressed, and as a result, a strong band of MAP2 was observed, which is an indicator of neuronal cell survival.

As shown in FIG. 20, dihydroginsenoside R b of 0.01 fg / m 1-1 ng Zm 1 significantly decreased the number of neurons in 7-potosis or apoptosis-like neurons. Turned out to be deterrent. That is, hydrin senoside R b! Is a ginsenoside R b! It is thought that it exerts a favorable effect on cells, especially nerve cells, in a slightly wider concentration range. Therefore, ginsenoside derivatives such as dihydroginsenoside Rb have an extracellular fluid concentration of 100 g / m1 or less, preferably 100 ng / m1 or less, more preferably 1 ng / m1 or less in the affected tissue. Inhibits apoptosis or apoptosis-like cell death of cells when m 1 or less, more preferably 0,000 lig / m 1-100 fg / m 1 Thus, it is thought to exert an excellent cytoprotective effect.

以上のようにジヒドロジンセノサイ ド R b 、 ジヒドロキシジンセノサイ ド R b 丄又はエポキシジンセノサイ ド R b などのジンセノサイ ド類誘導体は、 ジンセノ サイ ド R b iよりもかなり広い濃度域で神経細胞のアポト一シスもしくはアポトー シス様神経細胞死を抑止することが試験管内 (in vitro) の実験系で明らかにさ れたが、 実際に生体内 (in vivo) の実験系でもジヒドロジンセノサイ ド R b!、 ジヒドロキシジンセノサイ ド R b i又はエポキシジンセノサイ ド R b iなどのジン セノサイ ド類誘導体が、 ジンセノサイ ド R b iと同様に神経細胞保護作用を示すか どうかを本発明者は次にしらべた。 このため以下のごとく脳梗塞ラッ トを用いて、 ジンセノサイ ド類誘導体の 1つであるジヒドロジンセノサイ ド R b iの静脈内投与 実験を実施した。 -Proving that new agents, rooting and germination promoters can be newly created. The idea of creating a pharmaceutical composition for promoting tissue regeneration and reconstruction by using ginsenosides such as ginsenoside Rb, for which a synthesis method has not been established at this time, as a lead compound is limited to the inventor's knowledge. It has never been before. As described above, ginsenoside derivatives such as dihydroginsenoside R b, dihydroxy ginsenoside R b 丄, or epoxy ginsenoside R b can be used in neuronal cells over a much wider concentration range than ginsenoside R bi. In vitro (in vitro) experimental systems have shown that apoptosis or apoptosis-like neuronal cell death is inhibited by dihydroginsenoside in in vivo (in vivo) experimental systems. R b! The present inventors next examined whether or not a ginsenoside derivative such as dihydroxy ginsenoside R bi or epoxy ginsenoside R bi exhibits a neuroprotective effect similarly to ginsenoside R bi. Therefore, an intravenous administration experiment of dihydroginsenoside Rbi, one of the ginsenoside derivatives, was performed using a cerebral infarction rat as follows.
約 1 2〜 1 6週齢の雄性脳卒中易発症高血圧自然発症ラット (SH— S Pラッ ト、 体重 2 8 0 - 3 2 0 g ) を使用した。 同動物は 1 2時間ごとの明暗サイクル 室で飼育し、 水ならびに餌は自由摂取とした。 吸入麻酔下で同動物の左中大脳動 脈皮質枝 (MC A) を凝固 ·切離した。 ジヒドロジンセノサイ ド Rb を MC A永 久閉塞直後に単回静脈内注入し ( 6 /z g) 、 その後アルザミニ浸透圧ポンプを用 いて 2 4時間静脈内へジヒドロジンセノサイ ド R b tを持続注入 (6 ^ g/日) し た (n= 6) 。 なお、 本実験手技の詳細については本発明者 (阪中、 田中) の既 発表論文に記述されている (Igase K.et al., J. Cerebr. Blood Flow Metab. , 19. 298-306, 1999) 。 Approximately 12 to 16-week-old male stroke-prone spontaneously hypertensive rats (SH—SP rat, weighing 280 to 320 g) were used. The animals were housed in a 12-hour light / dark cycle room with free access to water and food. Under inhalation anesthesia, the left middle cerebral artery cortical branch (MCA) of the animal was coagulated and dissected. A single intravenous infusion of dihydroginsenoside Rb (6 / zg) immediately after permanent occlusion of MC A, followed by continuous infusion of dihydroginsenoside Rbt intravenously for 24 hours using an Alzamini osmotic pump (6 ^ g / day) (n = 6). The details of this experimental technique are described in published papers of the present inventors (Sakanaka and Tanaka) (Igase K. et al., J. Cerebr. Blood Flow Metab., 19.298-306, 1999).
なお、 MCAを永久閉塞した対照動物 (虚血コントロール動物) には同量の生 理食塩水 (v e h i c l e 担体又は媒体) のみを静脈内投与した ( n 7 ) 。 MCA永久閉塞後 2 4時間目に、 致死量のペントバルピタールをラッ 卜の腹腔内 に注入した。 同動物が死亡した直後に脳を摘出し、 2 mmの厚みの前額切片を作 成した。 同切片を、 1 %の塩化 2, 3 , 5—トリフエ二ルーテトラゾリゥム (2, 3, 5-triphenyl-tetrazolium chloride (TTC) ) 溶液に 3 0分間 3 7 tで 浸漬し、 1 0 %ホルマリンにて 1 2時間以上固定した。 結果を、 第 2 2図、 第 2 3図に示す。 第 2 2図は生理食塩水を投与した 2例を、 第 2 3図はジヒドロジン セノサイ ド R b iを静脈内投与した 2例を示す。 Control animals in which MCA was permanently occluded (ischemic control animals) were intravenously administered only the same amount of saline (vehicle carrier or vehicle) (n7). Twenty-four hours after MCA permanent occlusion, a lethal dose of pentovalpital was injected intraperitoneally into the rat. Immediately after the animal died, the brain was removed and a 2 mm thick forehead section was prepared. The sections were immersed in a 1% 2,3,5-triphenyltetrazolium chloride (2,3,5-triphenyl-tetrazolium chloride (TTC)) solution for 30 minutes at 37 t, and The cells were fixed in% formalin for 12 hours or more. The results are shown in FIGS. 22 and 23. FIG. 22 shows two cases in which physiological saline was administered, and FIG. 23 shows two cases in which dihydrozine cenoside Rbi was intravenously administered.
第 2 2図に示すごとく、 MC A永久閉塞後生理食塩水を投与したラッ トでは、
向かって左側の大脳皮質に、 T T Cで染色されない白色の脳梗塞病巣が明らかに 認められた。 一方、 第 2 3図に示すごとく、 ジヒドロジンセノサイ ド R b を MC A永久閉塞後に静脈内投与したラッ トでは脳梗塞病巣が顕著に縮小していた。 ジヒドロジンセノサイ ド R b:を静脈内投与した脳梗塞ラッ ト (n = 6) の脳梗 塞面積と、 v e h i c l e (担体又は媒体) のみを投与した脳梗塞ラッ トの脳梗 塞面積 (n= 7 ) とを比較した。 結果を第 24図に示す。 第 2 4図に示すごとく v e h i c l e (生理食塩水) 投与脳梗塞群の脳梗塞面積に比べて、 ジヒドロ ジンセノサイ ド R b i ( 2 H- R b i) 投与脳梗塞群の脳梗塞面積 ( i n f a r c t a r e a) は 3分の 1程度に縮小していた。 統計解析法は M a n n— W h i t n e y Uテストにより、 * *印は Pく 0. 0 1を示す。 As shown in Fig. 22, in rats receiving saline after MCA permanent occlusion, A white cerebral infarction lesion not stained with TTC was clearly observed in the left cerebral cortex. On the other hand, as shown in FIG. 23, cerebral infarction lesions were significantly reduced in rats to which dihydroginsenoside Rb was intravenously administered after permanent MCA occlusion. The cerebral infarction area of cerebral infarction rat (n = 6) administered intravenously with dihydroginsenoside Rb: and the cerebral infarction area of cerebral infarction rat administered vehicle (carrier or vehicle) only (n = 7). The results are shown in FIG. As shown in Fig. 24, the cerebral infarction area of the group treated with dihydro ginsenoside Rbi (2H-Rbi) was 3 times smaller than that of the group treated with vehicle (saline). It was reduced to about one-third. Statistical analysis was performed using the Mann-Whitney U test.
以上のことより、 ジヒドロジンセノサイ ド R b tの脳梗塞治療効果は、 WO 0 0 / 3 7 48 1号で開示されたジンセノサイ ド R b iの効果に匹敵するほど優れたも のであることが判明した。 また、 WO 0 0 / 48 6 0 8号に記載のジンセノサイ ド R b iと同様に、 ジヒドロジンセノサイ ド R b iなどのジンセノサイ ド類誘導体 が、 血管特に脳血管の再生及び/又は再構築を促進すると考えられた。 そこで本 発明者はさらにジヒドロジンセノサイ ド R b iの静脈内投与量を 2倍にして、 同様 に脳梗塞治療効果が得られるかどうかをしらべた所、 予想に反して優れた効果は 認められなかった。 すなわち、 WO 0 0/ 3 7 4 8 1号においてジンセノサイ ド R b tは体重 3 0 0 g程度の S H— S Pラッ トに対して 6 0 μ g/日の投与量でも 優れた脳梗塞治療効果を示したが、 ジヒドロジンセノサイ ド R b などのジンセノ サイ ド類誘導体はそのような高用量では脳梗塞治療効果及び/又.は脳血管再生 · 再構築促進作用を必ずしも発揮しないと考えられた。 From the above, it was found that the therapeutic effect of dihydroginsenoside Rbt on cerebral infarction was superior to the effect of ginsenoside Rbi disclosed in WO 00/37481. did. Similarly to ginsenoside R bi described in WO 00/48608, ginsenoside derivatives such as dihydroginsenoside R bi promote regeneration and / or reconstruction of blood vessels, particularly cerebral blood vessels. It was thought. Therefore, the present inventor further investigated whether or not the intravenous dose of dihydroginsenoside Rbi was doubled to obtain a therapeutic effect on cerebral infarction, and an unexpectedly superior effect was found. Did not. In other words, ginsenoside R bt in WO 00/3784 81 has an excellent therapeutic effect on cerebral infarction even at a dose of 60 μg / day for SH-SP rats weighing about 300 g. As shown, ginsenoside derivatives such as dihydroginsenoside Rb are not necessarily expected to exert a cerebral infarction treatment effect and / or a cerebral blood vessel regeneration / remodeling promotion effect at such a high dose. .
従って、 体重 3 0 0 g程度の脳梗塞ラッ トに対するジヒドロジンセノサイ ド R の至適投与量は、 ジンセノサイ ド R b tの至適投与量よりも低く、 詳細には 6 0 a gZ日以下好ましくは 1 2 /z g/日以下と考えられた。 このことから、 培養 実験においてはジヒドロジンセノサイ ド R b は、 ジンセノサイ ド R b:よりも幅 広い濃度域で神経細胞のアポトーシスもしくはアポトーシス様神経細胞死を抑止 するが、 生体内 ( i n v i v o) においてはジヒドロジンセノサイ ド R b iは、 ジンセノサイ ド R b iよりも低い投与用量域でのみ優れた脳梗塞治療効果及び脳血
管再生 ·再構築促進作用を発揮すると言える。 ただし、 ジヒドロキシジンセノサ イド R b!又はエポキシジンセノサイ ド R b などのジンセノサイド類誘導体は、 ジンセノサイ ド R b iと同等もしくはそれより 1 0 0 0倍程度多い投与量 ·濃度で ジンセノサイ ドと同様の効果 ·効能を示すと考えられる。 Therefore, the optimal dose of dihydroginsenoside R for a cerebral infarction rat with a body weight of about 300 g is lower than the optimal dose of ginsenoside R bt, and more preferably 60 agZ days or less. Was considered to be less than 1 2 / zg / day. Thus, in culture experiments, dihydroginsenoside Rb inhibits neuronal apoptosis or apoptotic-like neuronal cell death in a wider concentration range than ginsenoside Rb, but in vivo (in vivo). Dihydroginsenoside R bi has a superior cerebral infarction treatment effect and cerebral blood It can be said that it exerts the effect of promoting tube regeneration and reconstruction. However, dihydroxy ginsenoside R b! Alternatively, ginsenoside derivatives such as epoxy ginsenoside Rb are considered to exhibit the same effect and efficacy as ginsenoside at a dose and concentration equivalent to or approximately 100 times greater than that of ginsenoside Rbi.
本発明者は、 さらに低用量のジヒドロジンセノサイ ド R b iが神経組織に好まし い効果をもたらすことを確認するため、 ジヒドロジンセノサイ ド R b を 1. 2 UL g/日の用量で脊髄損傷ラッ ト (体重約 3 0 0 g) の静脈内へ 7日間持続注入し た。 ちなみに、 ジンセノサイ ド R b iを 6 0 g/日又は 1 2 g/日の用量で脊 髄損傷ラッ 卜の静脈内へ投与すると、 寝たきりの脊髄損傷ラッ 卜が起立すること を本発明者ら (阪中、 田中) はすでに見出しているが (WO 0 0/48 6 0 8 号) 、 ジンセノサイ ド R b iを体重 3 0 0 g程度の脊髄損傷ラッ トの治療に用いる ときの至適投与量は 6 0 g/日であることを本発明者らは P CT/ J P 0 0/ In order to confirm that even lower doses of dihydroginsenoside R bi have a favorable effect on nervous tissue, the present inventor has proposed that dihydro ginsenoside R b be administered at a dose of 1.2 UL g / day. A spinal cord injury rat (about 300 g body weight) was continuously infused intravenously for 7 days. The present inventors (Osaka et al.) Found that administration of ginsenoside Rbi at a dose of 60 g / day or 12 g / day intravenously to a spinal cord injury rat erects a bedridden spinal cord injury rat. Naka, Tanaka) (WO 00/48680), but the optimal dose when using ginsenoside Rbi to treat spinal cord injury rats weighing about 300 g is 6 The present inventors found that CT g / day was 0 g / day.

ハロセン、 笑気による吸入麻酔下で、 ラッ トの下位胸髄に 2 0 gの圧力を 2 0 分間負荷した後、 3 0分以上経過してから左大腿静脈にジヒドロジンセノサイ ド R b! ( 1. n ) を単回注入し、 さらに同静脈へジヒドロジンセノサイ ド R b ( 1. 2 g/日) をアルザミニ浸透圧ポンプにて 7 日間持続投与した。 対照動 物には同様のスケジュールで同量の生理食塩水 (v e h i c l e , 担体又は媒 体) を投与した。 結果を第 2 5図、 第 2 6図に示す。 Under inhalation anesthesia with halothane and laughter, after applying a pressure of 20 g to the lower thoracic spinal cord of the rat for 20 minutes, 30 minutes or more later, dihydroginsenoside Rb! (1.n) was injected once, and dihydroginsenoside Rb (1.2 g / day) was continuously administered to the same vein using an Alzamini osmotic pump for 7 days. Control animals received the same amount of saline (vehicle, carrier or vehicle) on a similar schedule. The results are shown in FIGS. 25 and 26.
第 2 5図及び第 2 6図の左側写真は脊髄損傷後 2 日目の生理食塩水投与ラッ ト を、 第 2 5図及び第 2 6図の右側写真は、 同時期のジヒドロジンセノサイ ド R b ( 1. 2 μ g /日) 投与ラッ トを、 それぞれ示している。 第 2 5図及び第 2 6図 の左側写真に示すごとく、 下位胸髄に 2 0 gの圧力を 2 0分間負荷された生理食 塩水投与ラッ トは、 脊髄損傷当日のみならず、 脊髄損傷後 2 日目にも両下肢の対 麻痺を呈した。 しかし下位胸髄に 2 0 gの圧力を 2 0分間負荷した後にジヒドロ ジンセノサイ ド R b iを静脈内へ持続投与すると、 脊髄損傷当日は下肢の対麻痺を 呈していたが、 第 2 5図及び第 2 6図の右側写真に示すごとく脊髄損傷後 2 日目 には、 両下肢の対麻痺が著しく改善し、 ラッ トは物につかまりながら立ち上がる ことができるようになった。 また、 ジヒドロジンセノサイ ド R b を 8 g/日又
は 6 0 ^ g /日の用量で脊髄損傷ラッ 卜の静脈内に投与しても優れた効果は認め られなかった。 The left photographs in Figs. 25 and 26 show the saline administration rats on the second day after spinal cord injury, and the right photographs in Figs. 25 and 26 show the dihydroginsenoside at the same time. The R b (1.2 μg / day) administration rate is indicated. As shown in the left-hand photographs in Figs. 25 and 26, the saline-administered rats with 20 g of pressure applied to the lower thoracic spinal cord for 20 minutes were not only treated on the day of spinal cord injury, but also after spinal cord injury. On the second day, he had paraplegia in both lower limbs. However, when 20 g of pressure was applied to the lower thoracic cord for 20 minutes, continuous administration of dihydroginsenoside Rbi intravenously showed paraplegia of the lower limb on the day of spinal cord injury, but the results were shown in Figs. On the second day after spinal cord injury, paraplegia of both lower limbs improved remarkably, and the rat was able to stand up while holding onto an object, as shown in the right photograph in Fig. 26. In addition, dihydroginsenoside Rb was added at 8 g / day. Did not show an excellent effect when administered intravenously in spinal cord injury rats at a dose of 60 ^ g / day.
以上のことより、 ジヒドロジンセノサイ ド R b ジヒドロキシジンセノサイド R b 又はエポキシジンセノサイ ド R b などのジンセノサイ ド類誘導体は、 ジン セノサイド R b と比較してもまったく遜色ないくらいに優れた脊髄損傷 ·神経外 傷治療効果を発揮することが判明した。 しかも、 体重 3 0 0 gの脊髄損傷ラット に対するジヒドロジンセノサイ ド R b の至適投与量は 1 . 2 a g /日前後もしく はそれ以下と考えられた。 すなわち、 ジヒドロジンセノサイ ド R b を神経外傷 - 頭部外傷 ·脊髄損傷治療用医薬組成物として利用するときは、 その至適投与量は ジンセノサイ ド R b tの 5 0分の 1前後又はそれ以下となることが発明された。 前 述のごとく.、 ジヒドロジンセノサイ ド R b!は、 高純度のジンセノサイ ド R b を 原材料として 9 7 %の収率で作成することができるので、 ジヒドロジンセノサイ ド R b ,は、 ジンセノサイ ド R b よりも効率良く、 神経外傷 ·脳卒中など脳 -神 経疾患の予防、 処置、 治療に利用され得ることになる。 Based on the above, ginsenoside derivatives such as dihydroginsenoside R b dihydroxy ginsenoside R b or epoxy ginsenoside R b have superior spinal cord injury comparable to ginsenoside R b. · It has been found that it has a therapeutic effect on nerve trauma. Moreover, the optimal dose of dihydroginsenoside Rb for spinal cord injured rats weighing 300 g was considered to be around 1.2 ag / day or less. That is, dihydro ginsenosides Sai de a R b neurotrauma - when used as head trauma, spinal cord injury pharmaceutical composition for the treatment, the optimal dose Jinsenosai de R b t 5 0 min 1 before and after or the It has been invented that: As mentioned above, dihydroginsenoside R b! Can produce high purity ginsenoside R b as a raw material in a 97% yield, so dihydro ginsenoside R b, is more efficient than ginsenoside R b, resulting in nerve trauma, stroke, etc. It could be used for the prevention, treatment and treatment of brain-neuropathy.
このように本発明は、 ジンセノサイ ド R b とほぼ同等の神経外傷、 脳卒中治療 効果を発揮し、 かつジンセノサイ ド R b よりも好ましくは低用量、 低濃度で効率 的経済的に臨床現場で使用し得るジンセノサイ ド類誘導体特にはジヒドロジンセ ノサイ ド R b を提供するものである。 ただし、 ジヒドロキシジンセノサイ ド R b 又はエポキシジンセノサイ ド R b などのジンセノサイ ド類誘導体は、 ジンセ ノサイ ド R b と同等もしくはそれよりも高い用量 ·濃度域で前記疾患や病態に効 果 ·効能を示すと考えられる。 As described above, the present invention exerts a therapeutic effect on nerve trauma and stroke almost equivalent to that of ginsenoside Rb, and is more preferably used at lower doses and lower concentrations than ginsenoside Rb in an economical and efficient manner. It provides the resulting ginsenoside derivatives, especially dihydroginsenoside R b. However, ginsenoside derivatives such as dihydroxy ginsenoside Rb or epoxy ginsenoside Rb are effective for the above-mentioned diseases and conditions at doses and concentrations equivalent to or higher than ginsenoside Rb. It is considered to show efficacy.
さて、 脊髄のある分節たとえば下位胸髄に圧負荷が加わり脊髄損傷が生じると、 同部の灰白質神経細胞のみならず同部の白質伝導路が障害を受ける。 ちなみに白 質伝導路は神経細胞の突起 (すなわち軸索又は樹状突起) とそれを絶縁するオリ ゴデンドロサイ ト由来の髄鞘 (ミエリン) からなる。 白質伝導路の障害はさらに 遠位部 (尾側) へと進展し、 かつ伝導路の起始細胞すなわち伝導路に線維を投射 している上位の神経細胞体 (すなわち起始細胞) の二次変性をもたらす。 このよ うにして、 圧負荷を受けた下位胸髄の白質伝導路の障害は、 伝導路の起始細胞体 (神経細胞体) ならびに下位胸髄以下 (すなわち腰髄、 仙髄) の伝導路の二次変
性を惹起することにより、 下肢の麻痺を引き起こす。 また、 下位胸髄の損傷によ り、 腰髄、 仙髄に対する上位の脳からの神経支配が途絶えるため、 さらに腰髄、 仙髄の灰白質でも神経細胞の二次変性が進行し、 両下肢の対麻痺が回復不能とな る。 また、 このような症状と並行して、 オリゴデンドロサイ トのアポトーシス、 脱髄などが生じることが知られている(Cr owe, M. J . e t a l . , Na t ure Med. , 3, 7 3-76, 1 997)。 When a segment of the spinal cord, such as the lower thoracic spinal cord, is overwhelmed with spinal cord injury, the gray matter nerve cells in the same area as well as the white matter pathway in the same area are damaged. By the way, the matter pathway consists of the processes of nerve cells (ie, axons or dendrites) and the myelin derived from oligodendrocytes that insulates them (myelin). The impairment of the white matter pathway further extends to the distal (caudal) side and is secondary to the cells that originate the pathway, or higher neuronal bodies that project fibers into the pathway (ie, the origin cells). Causes denaturation. In this way, impairment of the white matter pathways in the lower thoracic spine under pressure overload is caused by the origin of the pathways (neuronal cell bodies) and the pathways below the lower thoracic spinal cord (ie, lumbar spinal cord, sacral medulla). Secondary change of By causing sex, it causes paralysis of the lower limbs. In addition, since the lower thoracic spinal cord is injured, the innervation of the lumbar spinal cord and sacral cord from the upper brain is interrupted. Paralysis is irreversible. It is known that oligodendrocyte apoptosis and demyelination occur in parallel with these symptoms (Crown, MJ et al., Nature Med., 3, 73). -76, 1 997).
さらに、 脊髄損傷においては上記の神経組織固有の障害に加えて、 それに起因 する神経因性膀胱、 脳浮腫、 神経組織の浮腫、 浮腫、 排尿障害、 排便障害、 性機 能障害、 皮膚潰瘍、 褥創、 血管損傷などが生じる。 これらの、 疾患、 症状又は病 態の多くは、 脊髄損傷により運動神経のみならず、 自律神経や感覚神経などが傷 害を受けて機能不全に陥るため引き起こされると考えられる。 また、 血管損傷や 浮腫などは神経組織 (脊髄組織) が過度の機械的、 物理的圧力を受けたときに、 容易に生じることが知られている。 脊髄損傷に伴う上記の症状、 疾患、 病変又は 病態は、 程度の差はあれ、 頭部外傷においても認められる。 Furthermore, in spinal cord injury, in addition to the above-mentioned disorders specific to nerve tissue, the resulting neuropathic bladder, cerebral edema, edema of nerve tissue, edema, dysuria, defecation disorder, sexual dysfunction, skin ulcer, pressure Wounds and vascular damage occur. Many of these diseases, symptoms, or conditions are thought to be caused by injuries not only to motor nerves but also to autonomic nerves and sensory nerves due to spinal cord injury, resulting in malfunction. It is also known that vascular damage and edema easily occur when nerve tissue (spinal cord tissue) is subjected to excessive mechanical and physical pressure. The above-mentioned symptoms, diseases, lesions or conditions associated with spinal cord injury are also found in head trauma to varying degrees.

さて、 ジンセノサイ ド R b ジヒ ドロジンセノサイ ド R bい ジヒ ドロキシジ
ンセノサイ ド R b 又はエポキシジンセノサイ ド R b iは共通の効果、 効能、 用途 を有することがこれまで記述されてきたが、 次にこれら 4つの化合物のうちジン セノサイ ド R b iを選び、 ジンセノサイ ド R b が前述してきたように動物成長調 整用組成物又は飼料組成物となることを実験例に基づいて説明する。 このため、 動物としてたとえば淡水魚である "夕ナゴ" を用いた実験例を以下に示す。 By the way, ginsenoside R b dihydrazine ginsenoside R b It has been described so far that synthenoside Rb or epoxy ginsenoside Rbi has a common effect, efficacy and use. The fact that R b is a composition for controlling animal growth or a feed composition as described above will be described based on experimental examples. For this reason, an experimental example using the freshwater fish "Yunago" as an animal is shown below.
体長 3〜 5 c mの夕ナゴ (タイリクバラ夕ナゴ、 R h o d e u s o c e 1 1 a t u s o c e 1 1 a t u s ) 1 9匹を 2群に分け、 1 0匹は淡水 ( 5 0 リツ トル) のみにて 1 5で前後で 1 0日間、 9匹はジンセノサイ ド R b: ( 1 0 0 f g ノ m 1 ) を含有する淡水中で同条件で 1 0 日間飼育した。 その後、 すべての夕ナ ゴの尾びれ近傍の左側体表正中部に直径 2 mmの開放創を作成した。 開放創作成 には、 皮膚のバイオプシー用の器具 (トレパン) を用いた。 また、 開放創作成は、 淡水中の夕ナゴとジンセノサイ ド R b を含有する淡水中のタナゴを交互に使用し て行い、 開放創作成直後にもとの水槽に夕ナゴを戻した。 ちなみに、 夕ナゴに負 荷したこの開放創は、 ヒトに例えれば大腿動脈の損傷を伴う開放創ということが できる。 Evening nago with a body length of 3 to 5 cm (Tyrekubara evening nago, Rhodeusoce 11 atusoce 11 1 atus) 1 9 animals were divided into 2 groups, and 10 were around 15 in fresh water (50 liters) only. For 10 days, 9 animals were bred under the same conditions for 10 days in fresh water containing ginsenoside Rb: (100 fg no m 1). After that, open wounds with a diameter of 2 mm were created in the midline of the left body near the tail fins of all the locusts. An open wound was created using an instrument for skin biopsy (trepan). The open wound was created by alternately using a freshwater evening locust and a freshwater locust containing ginsenoside Rb, and the evening locust was returned to the original aquarium immediately after the open wound creation. By the way, this open wound that was loaded on the evening nago can be said to be an open wound with damage to the femoral artery when compared to humans.
開放創作成後、 8 日目に生存している夕ナゴを観察した。 なお、 餌としてメダ 力用の人工飼料をタナゴに与えた。 結果を第 2 7図、 第 2 8図、 第 2 9図に示す。 第 2 7図、 第 2 8図、 第 2 9図は図面に代わる写真である。 On the 8th day after the creation of the open wound, surviving locusts were observed. An artificial feed for medaka was fed to the locusts as bait. The results are shown in FIGS. 27, 28, and 29. Fig. 27, Fig. 28 and Fig. 29 are photographs replacing the drawings.
第 2 7図の開放創作成直後の代表例に示すごとく、 1 9匹の夕ナゴすべてに直 径 2 mmの開放創を作成した。 開放創作成後 8 日目には、 淡水のみで飼育した夕 ナゴは 1 0匹中 5匹がすでに死亡し、 生存していた 5匹も第 2 8図に示すごとく、 ほとんどのもの (4匹) がほぼ尾ひれ部分を欠落していた。 一方、 ジンセノサイ ド R b i d O O f g/m l ) を含有する淡水中で飼育したタナゴは、 第 2 9図に 示すごとく開放創作成後 8 日目でも 9匹中 7匹が生存しており、 しかも生存して いる 7匹には尾ひれ部分 (すなわち開放創作成部よりも遠位部組織) の欠落はほ とんど認められなかった。 As shown in the representative example immediately after creation of the open wound in Fig. 27, open wounds with a diameter of 2 mm were created on all 19 evening reefs. On the 8th day after the creation of the open wound, 5 out of 10 nago reared in freshwater alone had died, and most of the surviving 5 were as shown in Fig. 28. ) Was almost missing the fins. On the other hand, as shown in Fig. 29, seven out of nine surviving locusts reared in freshwater containing ginsenoside (R bid OO fg / ml) Seven of them had little missing fins (ie, tissue distal to the open wound).

Exp. Med., 188, 635-649, 1998) 。 Nerve cells were isolated from the fetal cerebral cortex of a 17-day-old rat using trypsin-EDTA, and plated on polyerysine-coated 24-well plates. After culturing for 16 hours in DMEM (Dulbecco's modified Eagle's medium) containing 10% fetal calf serum, replace the culture with serum-free medium for nerve cell culture containing insulin, transferrin, etc., for 3 to 4 days Cultured. On day 3 or 4 of the culture, sodium nitroprusside (SNP) was added at a concentration of 300; M, and the mixture was incubated for 10 minutes. Thereafter, the culture solution was replaced with EMEM (Eagle's minimum essentia 1 medium) containing dihydroxyginsenoside Rbi (0 to 100 ng / m1) and bovine serum albumin. Sixteen hours after SNP loading, neurons were lysed using Laemmli electrophoresis sample buffer, polyacrylamide gel electrophoresis was performed, and the electrophoresed proteins were transferred to nitrocellulose membrane. Thereafter, immunoplotting was performed using an antibody against the nerve cell-specific protein MAP2. Figure 2 shows the results. The details of the experimental procedure of the MAP2 immunobolot are described in a previously published paper by the present inventors (Sakanaka, Tanaka) (Wen, TC. Et al., J. Exp.

The first lane from the left is the control cultured neurons, and a clear MAP2 band (ie, a band for a marker of neurons) was observed. The SNP treatment caused many neurons to undergo apoptosis or apoptotic neuronal death, so that the MAP2 band was clearly weakened, as in the second lane from the left. When dihydroxyginsenoside R b is added to the culture medium at a concentration of 0.001 fg / m 1 (lane 4) to 100 ng / ml (lane 10), neuronal cells induced by SNP Apoptosis or apoptosis-like neuronal death is clearly inhibited, resulting in neuronal survival and apoptosis. In the figure, a strong band of MAP2, which is an indicator of process elongation, was observed. Therefore, ginsenoside derivatives such as dihydroxy ginsenoside R b L can inhibit apoptosis or apoptosis-like cell death of cells, especially neurons, in an optimal extracellular solution concentration range wider than ginsenoside Rbt. It is thought to exert an excellent cytoprotective effect. That is, ginsenoside derivatives such as dihydroxy ginsenoside R bi are similar to ginsenoside R bi or dihydro ginsenoside R b described in PCT / JPOO / 04102, and all diseases and conditions that cause cell death. It has been invented to be a pharmaceutical composition for the prevention, treatment or treatment of the disease. The lower part of FIG. 2 shows the densitometric analysis of the intensity of the MAP2 band by repeating the above immnoblot experiment. Statistical analysis was performed by ANOVA + Fisher's-PLSD.

After culturing in DMEM (Dulbecco's modified Eagle's medium) containing 10% fetal calf serum for 16 hours, replace the culture with serum-free medium for nerve cell culture containing insulin, transferrin, etc., for 3 to 4 days Cultured. On day 3 or 4 of the culture, sodium nitroprusside (SNP) was added at a concentration of 300, and the mixture was incubated for 10 minutes. Thereafter, the culture medium was replaced with EMEM (Eagle's minimum essential medium) containing epoxy ginsenoside Rb (0 to 100 ng / ml) and bovine serum albumin. Sixteen hours after SNP loading, nerve cells were lysed using a Laemli (Laemm1i) sample buffer for electrophoresis, polyacrylamide gel electrophoresis was performed, and the electrophoresed proteins were transferred onto a nitrocellulose membrane. After transcription, immunoblotting was performed using an antibody against the neuronal cell specific protein MAP2. The results are shown in FIG.

The first lane from the left is the control cultured neurons, and a clear MAP2 band (ie, a band for a marker of neurons) was observed. When treated with SNP, many of the neurons fell into apoptosis or apoptosis-like neuronal death, so that the MAP, 2 band was clearly weakened as in the second lane from the left. Epoxy ginsenoside Rbi can be added to the culture medium at a concentration of 1 fg / ml (lane 6) to 1 ng nom 1 (lane 9) to induce neuronal apoptosis or apoptotic neuronal death by SNP. Are clearly suppressed, and are thus indicators of neuronal survival and / or process extension. A strong band of MAP2 was observed. Therefore, ginsenoside derivatives such as epoxy ginsenoside Rbt inhibit apoptosis or apoptosis-like cell death of cells, especially nerve cells, in a wider optimal extracellular solution concentration range than ginsenoside Rbi. It is thought that by stopping the treatment, an excellent cytoprotective effect is exhibited. That is, ginsenoside derivatives such as epoxy ginsenoside R bi can be used in the same manner as ginsenoside R bi or dihydro ginsenoside R bi described in PCTZ JP 00/04102.

雄性ウィスターラッ ト (体重 3 0 0 g程度) に吸入麻酔下でジンセノサイ ド R b 1 ( 1 2 g) の生理食塩水溶解液を単回静脈内投与し、 続いてアルザミニ浸透 圧ポンプを用いてジンセノサイ ド R b iを 4日間静脈内へ持続注入 ( 1 2 g / 日) した。 その後、 吸入麻酔下で同動物の背部に直径 6 mmのパンチバイオプシ —を施し開放創を作成するとともに、 ジンセノサイ ド R b iの静脈内持続注入をさ らに 3日間継続した。 A single intravenous injection of a solution of ginsenoside Rb1 (12 g) in saline was administered to a male Wistar rat (body weight: about 300 g) under inhalation anesthesia, followed by use of an Alzamini osmotic pump. Ginsenoside R bi was continuously infused intravenously (12 g / day) for 4 days. Then, under inhalation anesthesia, a 6 mm diameter punch biopsy was applied to the back of the animal to create an open wound, and continuous intravenous infusion of ginsenoside Rbi was continued for another 3 days.
なお、 同様の開放創を作成して放置した対照動物には、 同量の生理食塩水のみ を静脈内投与した。 Control animals left with similar open wounds were given the same volume of saline only intravenously.
ジンセノサイ ド R b もしくは生理食塩水の静脈内持続注入終了後 2日目 (すな わち開放創作成後 5日目) に、 動物をペントバルビタールにて麻酔し、 4 %パラ ホルムアルデヒドを含有する 0. 1 Mリン酸緩衝液で経心的に灌流固定した。 そ の後、 開放創を含む皮膚組織を摘出し、 常法通りパラフィ ンに包埋した。 厚さ 5 程度のパラフィン切片を作成してへマトキシリンェォジン (H E) 染色に供 した。 その結果を第 8図に示す。 第 8図 Aはジンセノサイ ド R b i投与例、 第 8図 Bは生理食塩水投与例を示している。 " i " は痂皮 (incrustationもしくは esch ar) を、 e p ' は表皮 (epidermis) の重層扁平上皮 (stratified squamous e pi t el ium を、 b v は血管 (blood vessel) を示す。 On the second day after the end of the continuous intravenous infusion of ginsenoside Rb or saline, the animals were anesthetized with pentobarbital on day 5 after the open wound was prepared and contained 4% paraformaldehyde. Perfusion fixation was performed transcardially with 1 M phosphate buffer. After that, the skin tissue including the open wound was excised and embedded in paraffin as usual. Paraffin sections approximately 5 in thickness were prepared and subjected to hematoxylin-eosin (HE) staining. Figure 8 shows the results. FIG. 8A shows an example of ginsenoside Rbi administration, and FIG. 8B shows an example of physiological saline administration. "i" indicates crust (incrustation or esch ar), ep 'indicates stratified squamous epithelium of epidermis (epidermis), and bv indicates blood vessel.
第 8図 Aに示されたごとく、 ジンセノサイ ド R b 投与例では、 開放創作成後 5 日目には既に痂皮の下に明らかな表皮 (重層扁平上皮組織) が再生 .再構築して
おり、 表皮 (重層扁平上皮) 直下には赤血球で満たされた太い再生血管もしくは 新生血管が分布するとともに、 同血管から枝分れしたと思われる比較的細い血管 が真皮の結合組織や皮下組織内に密に存在していた-。 一方、 第 8図 Bに示された ごとく、 生理食塩水投与例では、 開放創作成後 5日目においても痂皮の下の表皮As shown in Fig. 8A, in the case of ginsenoside Rb administration, the epidermis (stratified squamous epithelial tissue) was clearly regenerated under the crust on day 5 after the open wound was created. There are thick regenerative blood vessels or new blood vessels filled with red blood cells underneath the epidermis (stratified squamous epithelium), and relatively thin blood vessels that seem to branch off from the blood vessels in the connective tissue and subcutaneous tissue of the dermis. -Existed densely. On the other hand, as shown in Fig. 8B, in the saline-administered example, the epidermis under the crust even on day 5 after the creation of the open wound
(重層扁平上皮) 再生は極めて不完全であり、 非常に薄い表皮組織の直下にある 再生血管も、 ジンセノサイ ド R b i静脈内投与例と比較して明らかに細かった。 そ のため将来瘢痕になると考えられる表皮下の結合組織には極めて細い血管が少数 散見されるのみであった。 従って、 ジンセノサイ ド R b の静脈内投与により、 皮 膚組織の再生 · 再構築が明らかに促進され、 開放創によってひとたび破綻 ·切断 された血管の再生 ·新生 ·再構築もジンセノサイ ド R b iの静脈内投与により促進 されることが発明されたことになる。 (Stratified squamous epithelium) Regeneration was extremely incomplete, and the regenerative blood vessels just below the very thin epidermal tissue were clearly smaller than those of ginsenoside Rbi intravenous administration. As a result, only a small number of extremely thin blood vessels were found in the connective tissue under the epidermis, which is thought to become scarred in the future. Therefore, the intravenous administration of ginsenoside Rb clearly promotes the regeneration and remodeling of the skin tissue, and the open wound regenerates the ruptured and cut blood vessels. In other words, it was invented to be promoted by intravenous administration.
以上の実施例により、 ジンセノサイ ド R b iは開放創を作成する前に静脈内投与 しても、 あるいは開放創を作成した後に静脈内投与しても、 優れた皮膚組織再生 According to the above examples, ginsenoside R bi can be administered to a patient intravenously before creating an open wound, or can be administered intravenously after creating an open wound.

(皮膚外用投与) したものであるが、 上から 1番目のプロぺトのみを外用塗布し たものに比べて開放創面積がやや縮小していた。 一方、 0 . 0 1重量%のジンセ ノサイ ド R b を含有するプロぺトを外用塗布 (外用投与) された上から 3番目の 開放創は、 上から 1番目の対照と比べて差異は認められなかった。 また、 第 1 0 図の上から 2番目と 3番目に示したごとく、 0 . 0 0 0 0 1重量%もしくは 0 . 0 0 0 0 0 1重量%のジンセノサイ ド R b を含有するプロぺトは、 0 . 0 0 0 1 重量%のジンセノサイ ド R b!を含有するプロべ卜よりも優れた効果を示した。 0 - 0 0 0 0 0 1重量%のジンセノサイ ド R b iの皮膚外用投与により、 再生した開放 創部より明らかな発毛が観察された。 このことは、 低濃度のジンセノサイド類特 にはジンセノサイ ド R b からなる皮膚外用剤を開放創に外用塗布もしくは外用噴 霧しても、 ジンセノサイド類特にはジンセノサイド R b iの静脈内持続投与とほぼ 同じ効果 ·効能が得られることを明らかにしている。 ジヒドロジンセノサイ ド R ジヒドロキシジンセノサイ ド R b エポキシジンセノサイ ド R b iなどのジ ンセノサイ ド類誘導体も同様の効果 ·効能を有すると考えられる。 実施例 1 4 (ジンセノサイ ド R b iによるヒト口腔粘膜咬傷治療 : その 1 ) (External application to the skin), but the open wound area was slightly smaller than that when only the first plot from the top was applied externally. On the other hand, the third open wound from the top, which was topically applied (external administration) with a pro- tein containing 0.01% by weight of ginsenoside Rb, showed no difference compared to the first control wound from the top. I couldn't. In addition, as shown in the second and third figures from the top of FIG. 10, a plot containing 0.00001% by weight or 0.00001% by weight of ginsenoside R b was used. Is 0.0000% by weight of ginsenoside R b! Showed an effect superior to that of a probe containing. By topical administration of ginsenoside Rbi at 0-0001% by weight, clear hair growth was observed from the regenerated open wound. This is almost the same as the continuous intravenous administration of ginsenosides, especially ginsenoside R bi, even when a topical skin preparation consisting of ginsenosides, especially ginsenoside Rb, is externally applied or sprayed onto open wounds. Effects · Efficacy is obtained. It is also considered that dixenoside derivatives such as dihydroginsenoside R dihydroxyginsenoside Rb epoxy ginsenoside Rbi have the same effect and efficacy.

午後 2時頃に阪中は歯科治療後左三又神経第三枝の浸潤麻酔ならびに歯根膜麻酔 が醒める前に、 空腹のあまり遅い昼食をとり始めた。 1 5分以内に自身の左下唇 粘膜を 3度嚙んでしまい、 その後口腔内に鉄の味覚 (血液) を感知したので、 鏡 にて咬傷を確認した所、 少なくとも 5ケ所に口腔内粘膜のびらんもしくは欠損を 認め、 さらに 1ケ所に血腫を認めた。 このまま、 放置すると数日以内にァフタ性 口内炎を併発し、 完治までに 1週間から 1 0 日を要すると判断したので、 本発明 者の動物実験で効果 ·効能が確認されている低濃度 (0 . 0 0 0 0 1重量%) の ジンセノサイ ド R b iを含有したプロべトを、 口腔粘膜のびらんもしくは欠損をき たした領域 5ケ所、 ならびに血腫の部位 1ケ所に少量外用塗布した。 外用塗布は、 毎食前後ならびに間食前後に実施した。 すなわち 1 日 6 — 1 0回に分けて咬傷部 位に 0 . 0 0 0 0 1重量%のジンセノサイ ド R b iを含有するプロべトを口唇粘膜 へ外用塗布した。 咬傷後 9 6時間目の口唇粘膜の写真を第 1 1図に示す。 One S3- At around 2 pm, Sakanaka began to eat a very late lunch on an empty stomach before the awakening of infiltration anesthesia and periodontal anesthesia of the third branch of the left trifurcation nerve after dental treatment. Within 15 minutes, his left lower lip mucous membrane was swollen three times, and after that he sensed the taste (blood) of iron in the oral cavity. Or a defect was observed, and hematoma was observed in one more place. If left untouched, aphthous stomatitis would occur within a few days, and it was determined that it would take 1 week to 10 days for complete cure. (0.001% by weight of ginsenoside Rbi) was applied topically in small amounts to 5 eroded or defective areas of the oral mucosa and 1 hematoma site. External application was performed before and after each meal and before and after a snack. That is, a probe containing 0.001% by weight of ginsenoside R bi at the bite site was applied topically to the lip mucosa in 6 to 10 times a day. A photograph of the lip mucosa 96 hours after the bite is shown in FIG.
第 1 1図の写真に示すごとく、 咬傷後 9 6時間目には白矢頭で示すごとく血腫 は残っているが、 その他の黒矢頭で示した口唇粘膜の咬傷部 (すなわちびらんも しくは欠損をきたした口腔粘膜) は、 わずかに発赤がみられるのみでほぼ完全に 上皮化が進んでおり、 明らかに創傷が治癒したと考えられた。 なお、 0 . 0 0 0 0 1重量%のジンセノサイド R b iを含有するプロべトを咬傷部に外用塗布し始め てからは、 創部における疼痛も顕著に軽減した。 As shown in the photograph of Fig. 11, at 96 hours after the bite, a hematoma remains as indicated by a white arrowhead, but the bite of the labial mucosa indicated by a black arrowhead (that is, erosion or defect is not observed). The epithelium of the oral mucosa was slightly reddened, and the epithelization was almost complete. It was considered that the wound had clearly healed. In addition, since topical application of a probe containing 0.0001% by weight of ginsenoside Rbi to the bite site was started, pain at the wound site was also remarkably reduced.
これらのことから本発明のジヒドロキシジンセノサイ ド R b i又はエポキシジン セノサイ ド R b iも同様な活性があることが示される。 実施例 1 5 (ジンセノサイ ド R b による口腔粘膜咬傷治療:その 2 ) These facts indicate that the dihydroxy ginsenoside R bi or the epoxy ginsenoside R bi of the present invention has a similar activity. Example 15 (Treatment of Oral Mucosa Bite with Ginsenoside R b: Part 2)
次に本発明者の一人 (阪中) は、 平成 1 2年 5月 2 6 日昼食中に再度左下唇粘 膜を嚙んでしまったので、 0 . 0 0 0 0 1重量%のジンセノサイ ド R b tを含有す るプロぺトを同様の方法で咬傷部へ外用塗布した。 咬傷直後の写真を第 1 2図の 左側に、 咬傷後 7 2時間目の写真を第 1 2図の右側に示す。 Next, one of the present inventors (Sakanaka) re-opened the left lower lip mucous membrane during lunch on May 26, 2012, so that 0.001% by weight of ginsenoside R was used. A plot containing bt was externally applied to the bite site in the same manner. The photograph immediately after the bite is shown on the left side of FIG. 12, and the photograph 72 hours after the bite is shown on the right side of FIG.
第 1 2図に示すごとく、 低濃度のジンセノサイ ド R b!を粘膜へ外用投与すれば, ァフタ性口内炎を併発することなく咬傷が速やかに治癒することが判明した。 As shown in Fig. 12, low concentration of ginsenoside R b! It was found that bitumen healed quickly without topical aphthous stomatitis when topically applied to the mucosa.
これらのことから本発明のジヒドロキシジンセノサイ ド R b i又はエポキシジン
セノサイ ド R b Lも同様な活性があることが示される。 実施例 1 6 (ジンセノサイ ド R b tによるポトスの挿し木の新生 ·再生促進効果) 本発明者らは、 ジンセノサイド類特にジンセノサイ ド R b が皮膚組織や口腔粘 膜組織のみならず、 植物組織の新生 ·再生もしくは再構築をも促進するかどうか を調べた。 このため植物組織として観葉植物の 1つであるポトス (学名、 Epipre munum aureum; 和名 : ォゥゴンカズラ ;英名 : golden pot os) を選んだ。 発明者 の一人 (田中) の部屋にあるポトスの親株から、 類似した挿し木を 6本採取し、 3本は水のみを用いて水栽培し、 残り 3本は 1 0 0 f g /m 1 のジンセノサイ ド R b iを含有する水中で栽培した。 栽培 1 3 日目の挿し木の写真を第 1 3図に示す < 第 1 3図の左側は水のみで挿し木 (ポトスの茎と枝) を水栽培したものであり、 第 1 3図の右側は、 低濃度のジンセノサイ ド R b i ( 1 0 0 f g/m 1 ) を含有す る水で挿し木を水栽培したものである。 明らかに低濃度のジンセノサイ ド R b tFrom these facts, the dihydroxy ginsenoside R bi or the epoxyzine of the present invention Cenoside RbL is also shown to have similar activity. Example 16 (Effect of ginsenoside R bt for promoting the regeneration and regeneration of cuttings of pothos) The present inventors have found that ginsenosides, particularly ginsenoside R b, not only produce skin tissues and oral mucosal tissues, but also produce plant tissues. We examined whether it would also promote regeneration or reconstruction. For this reason, pothos (scientific name, Epipre munum aureum; Japanese name: o ゥ gonkazura; English name: golden pot os), one of the foliage plants, was selected as the plant tissue. Six similar cuttings were collected from the parent plant of Potos in the room of one of the inventors (Tanaka), three were hydroponically grown using only water, and the remaining three were 100 fg / m1 ginsenosides. Cultivated in water containing R bi. Fig. 13 shows a photograph of the cuttings on the 13th day of cultivation. <The left side of Fig. 13 shows the cuttings (pothos stems and branches) hydroponically grown with water only. The right side of Fig. 13 shows Cuttings were hydroponically grown with water containing low concentrations of ginsenoside R bi (100 fg / m 1). Clearly low ginsenoside R bt
( 1 0 0 f g/m 1 ) を含有する水で、 ポトスの挿し木を水栽培した場合には水 のみで水栽培したものと比べて、 根の伸長が促進された。 (100 fg / m 1), the root elongation was promoted when pothos cuttings were cultivated hydroponically as compared to those cultivated with water alone.
次に、 本発明者らは、 前述の挿し木を引き続き水栽培に供し、 2 2 日目に再度 写真撮影を実施した。 結果を第 1 4図に示す。 第 1 4図の左側は、 水のみでポト スの挿し木を 3本 2 2 日間水栽培したものであり、 第 1 4図の右側は、 低濃度の ジンセノサイ ド R b i ( 1 0 0 f g/m 1 ) を含有する水で挿し木を水栽培したも のである。 なお、 水栽培用の水もしくはジンセノサイ ド R b iを含有する水は、 1 週間に一度交換した。 さらに、 27日目にも発根部位を観察した。 Next, the present inventors continued the hydroponic cultivation of the cuttings described above, and again photographed them on the 22nd day. The results are shown in FIG. The left side of Fig. 14 shows three potato cuttings cultivated with water only for 22 days, and the right side of Fig. 14 shows low concentration of ginsenoside R bi (100 fg / m 1 Cuttings were hydroponically grown with water containing). Water for hydroponics or water containing ginsenoside R bi was replaced once a week. Further, on the 27th day, the rooting site was observed.
第 1 4図に示すごとく、 低濃度のジンセノサイ ド R t^ ( 1 0 0 f g/m 1 ) を 含有する水で挿し木を 2 2日間水栽培すると、 多くの根が新生もしくは再生し、 水栽培用ガラス容器に接するまでに伸長した。 さらに 27日目になると低濃度のジ ンセノサイ ド R b i d O O i g/m 1 ) を含有する水で栽培されたポトスの挿し 木 3本すべてに、 一次発根部位より明らかな二次発根が観察された。 しかし、 水 のみで栽培されたポトスの挿し木 3本には、 まったく二次発根は認められなかつ た。 従って、 本実験結果より低濃度 ·低用量のジンセノサイ ド類特にはジンセノ . サイ ド R b !もしくはジンセノサイ ド R b tを含有する天然物又はそのエキスは皮
膚組織ゃヒト口腔粘膜組織のみならず、 植物組織の新生 ·再生もしくは再構築を も促進することが発明された。 As shown in Fig. 14, when cuttings are cultivated for 22 days in water containing low concentration of ginsenoside R t ^ (100 fg / m 1), many roots are regenerated or regenerated, and glass for hydroponics is used. It stretched to touch the container. On the 27th day, secondary rooting was observed in all three cuttings of pothos grown in water containing low concentrations of ginsenoside (R bid OO ig / m 1). Was done. However, no secondary rooting was observed in any of the three cuttings of pothos grown on water alone. Therefore, natural products containing ginsenoside Rb! Or ginsenoside Rbt or extracts thereof at lower concentrations and lower doses than the results of this experiment, especially ginsenoside Rb! It has been invented to promote the regeneration, regeneration or reconstruction of not only skin tissue-human oral mucosal tissue but also plant tissue.
これらのことから本発明のジヒドロキシジンセノサイ ド R b i又はエポキシジン セノサイ ド R b iも同様な活性があることが示される。 実施例 1 7 ( 1 0— 4重量%〜 1 0— 8重量%のジンセノサイ ド R b を含有するプロ ぺトによる開放創治療) These facts indicate that the dihydroxy ginsenoside R bi or the epoxy ginsenoside R bi of the present invention has a similar activity. Example 1 7 (open wound treatment with pro pane you want to contain 1 0- 4 wt% to 1 0 8% by weight of Jinsenosai de R b)

第 1 5図に示すごとく 1 0一6重量%から 1 0— 8重量%のジンセノサイ ド R b iを 含有するプロぺト (すなわち 1 O n gZm lから 1 0 O p g/m lの濃度のジン セノサイ ド R b を開放創に外用塗布しても 1 0— 5重量%のジンセノサイ ド R b を含有するプロべ卜と同様に明らかに、 プロべトのみを外用塗布した開放創に比 ベて、 創傷治癒が促進された。 従って、 ジンセノサイ ド類特にはジンセノサイ ド R b iを皮膚外用剤として使用するときは、 外用剤における濃度は 1 0— 8重量%前 後もしくはそれ以下に設定することが好ましいと考えられた。 従って、 化粧品組 成物、 皮膚外用組成物又は健康薬組成物として、 ジンセノサイ ド類特にはジンセ ノサイ ド R b i、 薬用人蔘粗サポニン分画、 薬用人蔘エキスもしくは薬用人蔘を使 用するときも、 化粧品、 発毛育毛剤、 ケミカルピーリング剤、 又は健康薬におけ るその濃度は 0. 0 0 1重量%未満、 好ましくは 0. 0 0 0 0 2重量%未満、 よ り好ましくは 0. 0 0 0 0 1重量% ( 1 0— 5重量%) 以下、 さらに好ましくは 0. 0 0 0 0 0 0 0 1重量% ( 1 0— 8重量%) 以下に設定することが必要である。
前述の実験例において、 プロべトのみを外用塗布した開放創の面積を分母にと り、 1 0— 4重量%から 1 0— 8重量%のジンセノサイ ド R b iを外用塗布した開放創 の面積を分子にとり、 その比を算出した。 結果を第 1 6図に示す。 第 1 6図に示 すごとく、 低濃度のジンセノサイ ド R b tを開放創に外用投与すると有意に創傷治 癒が促進された。 統計解析は、 ANOVA+S ch e i f e ' s p o s t ho c t e s Uこよる。 *印は P < 0 . 0 5を、 * *印は P < 0 . 0 1を示す。 1 0 - 8 %前後のジンセノサイ ド R b!を外用塗布すると開放創の面積は、 対照群の 4分の 1程度に縮小するので、 低 濃度のジンセノサイ ド R b!を外用投与することにより開放創の体積はおよそ、 コ ントロールの 8分の 1に縮小したと考えられる。 First from 5 Jinsenosai de 1 0 one 6 wt% of 1 0 8 wt% as shown in FIG R bi containing Puropeto (i.e. 1 O n gZm l 1 0 of O pg / ml concentration Jin Senosai de R b and Purobe Bok and apparently similarly containing Jinsenosai de R b 1 0 5 wt% be externally applied to open wounds, Te ratio base to open wounds that topical application of Purobetonomi, wound healing was promoted. Therefore, when the Jinsenosai earths especially the use of Jinsenosai de R bi as a skin external preparation, it is preferable that the concentration is set at or less after 1 0- 8% by weight before the external preparation Therefore, ginsenosides, especially ginsenoside R bi, ginseng crude saponin fraction, ginseng extract or ginseng, as cosmetic compositions, skin external compositions or health care compositions When using cosmetics, Its concentration in hair growth agents, chemical peels or health agents is less than 0.001% by weight, preferably less than 0.002% by weight, more preferably 0.0000. wt% (1 0 5 wt%) or less, more preferably needs to be set to 0.0 0 0 0 0 0 0 1 wt% (1 0 8% by weight) or less. In the experimental example described above, Ri bets in the denominator the area of open wound that topical application of Purobetonomi, area of the open wounds from 1 0 4% by weight 1 0 8% by weight of Jinsenosai de R bi and topical application Was taken as the numerator, and the ratio was calculated. The results are shown in FIG. As shown in FIG. 16, topical administration of a low concentration of ginsenoside Rbt to open wounds significantly promoted wound healing. Statistical analysis is based on ANOVA + Scheife 'spost hoctes U. The * mark indicates P <0.05, and the ** mark indicates P <0.01. 1 0 - 8% before and after Jinsenosai de R b! Topical application reduces the open wound area to about one-fourth that of the control group, so low concentrations of ginsenoside R b! It is thought that the volume of the open wound was reduced to approximately one-eighth of the control by topical administration of.
これらのことから本発明のジヒドロキシジンセノサイ ド R b 又はエポキシジン セノサイ ド R b iも同様な活性があることが示される。 実施例 1 8 (低濃度のジンセノサイ ド R b i又はジンセノサイ ド誘導体を含有する プロべトによる口腔粘膜熱傷もしくはァフタ性口内炎治療) These results indicate that the dihydroxy ginsenoside R b or the epoxy ginsenoside R bi of the present invention has the same activity. Example 18 (treatment of oral mucosal burns or aphthous stomatitis with probe containing low concentration of ginsenoside Rbi or ginsenoside derivative)
熱い飲食物を急いで口腔内へ入れたときに舌粘膜、 口唇粘膜、 硬口蓋粘膜、 軟 口蓋粘膜が熱傷をこうむり、 粘膜上皮が脱落し、 粘膜のびらんや発赤が出現する ことがよくある。 もちろんこのような熱傷には疼痛を伴うことが常である。 また、 口腔粘膜の咬傷や熱傷後にもしくは原因が定かではないときにも、 しばしばァフ タ性口内炎が生じ、 1週間から 1 0 日程度、 常時口腔内に疼痛を覚え食事をする のも不自由なことがしばしばである。 上記のような口腔粘膜の熱傷ゃァフタ性口 内炎に対して、 1 0— 3重量%未満、 好ましくは 2 X 1 0— 5重量%未満、 より好ま しくは 1 0— 5重量%以下、 さらに好ましくは 1 0— 7重量%以下のジンセノサイ ド R b!を含有する軟膏を 1 日に 1一 1 0回、 特に食事前後に粘膜病変部に塗布すれ ば、 疼痛も軽減し、 粘膜欠損もしくは創傷の治癒が促進される。 なお、 口腔粘膜 外用剤としてジンセノサイ ド類特にジンセノサイ ド R b iを使用するときの基剤と して、 デキサルチン軟膏ゃケナログ又はァフ夕ツチと同様の基剤を用いてもよい。 また、 口腔粘膜外用剤に含有されるジンセノサイ ド類特にはジンセノサイ ド R b !の至適濃度は、 皮膚外用剤におけるジンセノサイ ド類の至適濃度より、 1 0倍— 1 0 0 0倍程度高いと考えられる。 もちろん、 ジンセノサイ ド類のかわりに同濃

Of course, such burns are usually accompanied by pain. Also, after bite or burns on the oral mucosa or when the cause is not clear, often a stomatitis occurs, and from 1 week to 10 days, it is inconvenient to have pain in the oral cavity and eat regularly. Is often the case. 10 to less than 3 % by weight, preferably 2 × 10 to less than 5 % by weight, more preferably 10 to 5 % by weight or less, for the burnt stomatitis of the oral mucosa as described above. More preferably, 10 to 7 % by weight or less of ginsenoside R b! If applied to a mucosal lesion 11 to 10 times a day, especially before and after a meal, pain is reduced and the healing of mucosal defects or wounds is promoted. As a base when ginsenosides, particularly ginsenoside Rbi, is used as an oral mucosal external preparation, the same base as that of dexartin ointment ゃ enalog or Affatti may be used. Also, ginsenosides contained in oral mucosal external preparations, especially ginsenoside Rb! Is considered to be about 10 to 100 times higher than the optimum concentration of ginsenosides in the external preparation for skin. Of course, instead of ginsenosides, A ginsenoside derivative may be used at a higher concentration or about 1000 times higher. When ginsenoside Rb is used as a composition for an external mucosal preparation, the upper limit of the concentration is considered to be 0.1% by weight or less.
これらのことから本発明のジヒドロキシジンセノサイ ド R b i又はエポキシジン セノサイ ド R b も同様な活性があることが示される。 実施例 1 9 (ジヒドロジンセノサイ ド R b tを含有する皮膚外用剤による開放創治 療) These results indicate that the dihydroxy ginsenoside R bi or the epoxy ginsenoside R b of the present invention has the same activity. Example 19 (Open wound treatment with skin external preparation containing dihydroginsenoside Rbt)
次に、 本発明者らはジンセノサイ ド類誘導体が、 ジンセノサイ ド R b iと同様に 低濃度 ·低用量で組織再生 ·再構築を促進するかどうかをしらべた。 このため、 ジンセノサイ ド類誘導体の 1つとしてジヒドロジンセノサイ ド R b iを選び、 同化 合物の開放創治療効果を検討した。 なお、 ジヒドロジンセノサイ ド R b tの詳細に ついては P CT/ J P 0 0 / 0 1 0 2号 (薬用人蔘からなる脳細胞または神経 細胞保護剤) 及び P CT/ J P 0 0 / 0 5 5 54号 (ジンセノサイ ド R b からな る皮膚組織再生促進剤) に記載されている。 吸入麻酔下でラッ ト (n = 4) の背 部に直径 6 mmのパンチバイオプシーを 5ケ所に施し開放創を作成した。 その後、 各開放創に、 ジヒドロジンセノサイ ド R b をそれぞれ 0. 0 0 0 1重量% ( 1 0 — 4重量%) 、 0. 0 0 0 0 1重量% ( 1 0— 5重量%) 、 0. 0 0 0 0 0 1重量% ( 1 0— 6重量%) 、 0. 0 0 0 0 0 0 1重量% ( 1 0— 7重量%) 、 の濃度で、 含 有するプロぺトを 1 日単回 0. 1 gを 9 日間外用塗布した。 コントロールにはプ ロぺトのみを外用塗布した。 その後、 麻酔により動物を安楽死させた直後に創傷 部皮膚を採取し写真撮影を実施した。 採取した皮膚組織は固定液中で保存した。 結果を第 1 7図に示す。 Next, the present inventors examined whether or not ginsenoside derivatives promote tissue regeneration and remodeling at low concentration and low dose, similarly to ginsenoside Rbi. For this reason, dihydroginsenoside Rbi was selected as one of the ginsenoside derivatives, and the open wound treatment effect of the compound was examined. Incidentally, dihydro ginsenosides Sai de R For b t of detail P CT / JP 0 0/0 1 0 2 No. (ginseng Brain cell or nerve cell-protective agents comprising ginseng) and P CT / JP 0 0/0 5 No. 54 (Skin tissue regeneration promoter consisting of ginsenoside Rb). Under inhalational anesthesia, 6 mm diameter punch biopsies were applied to the back of the rat (n = 4) at five locations to create open wounds. Thereafter, each open wounds, dihydro ginsenosides Sai de R b each 0.0 0 0 1 wt% (1 0 - 4% by weight), 0.0 0 0 0 1 wt% (1 0 5 wt%) , 0.0 0 0 0 0 1 wt% (1 0 6 wt%), 0.0 0 0 0 0 0 1 wt% (1 0-7 wt%), at a concentration of, a Puropeto having free 0.1 g once daily was applied externally for 9 days. For the control, only the plot was applied externally. Immediately after the animals were euthanized by anesthesia, the wound skin was collected and photographed.

Res. , 53, 415-425, 1998) 。 この培養実験系を用いて、 本 発明者らはすでにジンセノサイ ド R b iが 1 n gZm 1以下の細胞外液濃度で、 よ り詳細には 1〜 1 0 0 ί g /m 1 という至適細胞外濃度域で神経細胞のアポトー シスもしくはアポト一シス様神経細胞死を抑止することを見出している (WO 0 0ノ 3 7 4 8 1号、 ジンセノサイ ド R b iからなる脳細胞又は神経細胞保護剤) 。 そこで、 同様の実験系を用いてジヒドロジンセノサイ ド R b iの神経細胞保護作用 をしらべた。 The present inventors (Sakanaka, Tanaka) and colleagues reported that short-term exposure of cultured neurons to the nitric oxide donor, sodium nitroplumid sodium (SNP), resulted in neuronal apoptosis or apoptotic neuronal death. (Toku K. et al., J. Neurosci. Res., 53, 415-425, 1998). Using this culture experiment system, the present inventors have already found that ginsenoside Rbi has an optimal cell concentration of 1 ng / ml at an extracellular solution concentration of 1 ng / ml or less. It has been found that apoptosis or apoptosis-like nerve cell death of nerve cells is inhibited in the external concentration range (WO 00/37841, a brain cell comprising ginsenoside Rbi or a neuroprotective agent). ). Therefore, using a similar experimental system, the neuroprotective effect of dihydroginsenoside Rbi was examined.

After culturing in DMEM (Dulbecco's modified Eagle's medium) containing 10% fetal bovine serum for 16 hours, the culture medium was replaced with a serum-free medium for nerve cell culture containing insulin, transferrin, etc. Cultured for 3-4 days. On the third or fourth day of the culture, sodium nitroprusside (SNP) was added at a concentration of 300 / ΔtM, and the mixture was incubated for 10 minutes. Thereafter, the culture solution was replaced with EMEM (Eagle's minimum essential medium) containing dihydroginsenoside Rb (0 to 1 ng / m1) and bovine serum albumin. Sixteen hours after SNP loading, neurons were lysed using a Laemmli electrophoresis sample buffer, polyacrylamide gel electrophoresis was performed, and the electrophoretic proteins were transferred to nitrocellulose membrane. Immunoblotting was performed using an antibody against P2. Quantify neuronal cell viability Therefore, the immunostained MAP2 band was analyzed by densitometry. The results are shown in FIGS. 19 and 20. FIG. 21 shows an NMR chart (400 MHz, CD 3 OD) of dihydroginsenoside R bi for reference.
第 1 9図は MAP 2 (microtuble- associated protein 2) のィムノブロット の結果を示す図面に代わる写真である。 左から 1番目のレーンがコントロールの 培養神経細胞であり、 明らかな MAP 2のパンド (すなわち神経細胞のマーカ一 のバンド) が認められた。 S NP処理をすると、 多くの神経細胞がアポトーシス もしくはアポトーシス様神経細胞死に陥るので、 MAP 2のバンドが左から 2番 目のレーンのごとく明らかに弱くなつた。 ジヒドロジンセノサイ ド R b を 0. 0 1 f g/m 1 (レーン 3) から 1 n g/m 1 (レーン 7 ) の濃度で培養メディゥ ムに添加しておくと、 S N Pによる神経細胞のアポトーシス又はアポト一シス様 神経細胞死が明らかに抑止され、 その結果神経細胞の生存の指標である MA P 2 の強いバンドが観察された。 FIG. 19 is a photograph instead of a drawing showing the result of immunoblot of MAP 2 (microtuble-associated protein 2). The first lane from the left is a control cultured neuron, in which a clear MAP2 band (ie, a band that is a marker for neurons) was observed. When treated with SNP, many neurons undergo apoptosis or apoptotic-like neuronal death, so the MAP2 band was clearly weakened, as in the second lane from the left. When dihydroginsenoside Rb is added to the culture medium at a concentration of 0.01 fg / m1 (lane 3) to 1 ng / m1 (lane 7), apoptosis of neurons by SNP or Apoptosis-like neuronal death was clearly suppressed, resulting in a strong band of MAP 2, an indicator of neuronal survival.

As shown in Figure 20, 0.1 Olf gZm l- 1 ng / m 1 of dihydroginsenoside Rb significantly inhibited neuronal apoptosis or apoptotic neuronal death. found. In other words, dihydroginsenoside Rb is considered to exert a favorable effect on cells, especially nerve cells, in an optimal concentration range wider than ginsenoside Rb. Therefore, ginsenoside derivatives such as dihydroginsenoside R b ^ dihydroxy ginsenoside R b or epoxy ginsenoside R b have an extracellular fluid concentration of 100 g / m 1 or less, preferably 100 g, in the affected tissue. Apoptosis or apoptosis-like cell death of cells at 0 ng / m 1 or less, more preferably 1 ng Zm 1 or less, and still more preferably 0.0000 fg Zm 1 — 100 fg Zm 1. It is thought that the inhibition will exert an excellent cytoprotective effect. The * mark indicates P <0.01>, and the ** mark indicates P <0.0001.
また、 ジヒ ドロジンセノサイ ド R b !を 0. 0 0 0 0 1重量% ( 1 0 重量%) 含有する皮膚外用剤が優れた開放創治療効果を示すという前述の実験結果から判 断すると、 ジヒドロジンセノサイ ド R b ジヒドロキシジンセノサイ ド R b!又
はエポキシジンセノサイド R b iなどのジンセノサイ ド類誘導体はやはり、 患部組 織における細胞外液濃度が 1 0 0 μ g /m 1以下、 好ましくは 1 0 0 n g /m 1 以下、 より好ましくは 1 n g /m 1以下、 さらに好ましくは 0 . 0 0 0 0 1 f g /m 1 — 1 0 0 f g /m 1のときに優れた生体組織の再生 ·再構築を作用を発揮 すると言える。 Also, from the above-mentioned experimental results that the external preparation for skin containing 0.001% by weight (10% by weight) of dihydrozine cenoside R b! Senoside R b Dihydroxyzine Senoside R b! or Ginsenoside derivatives such as epoxy ginsenoside Rbi still have an extracellular solution concentration of 100 μg / m1 or less, preferably 100 ng / m1 or less, more preferably 1 ng / m1 or less in the affected tissue. When m 1 or less, and more preferably 0.0000 fg / m 1 —100 fg / m 1, it can be said that excellent regeneration and reconstruction of living tissue can be exerted.
これらのことから本発明のジヒドロキシジンセノサイ ド R b i又はエポキシジン セノサイ ド R b:も同様な活性があることが示される。 実施例 2 1 (ジヒドロジンセノサイ ド R b tの脳梗塞治療効果判定実験) These results indicate that the dihydroxy ginsenoside R bi or the epoxy ginsenoside R b of the present invention also has a similar activity. Example 21 (Evaluation experiment for therapeutic effect of dihydroginsenoside Rbt on cerebral infarction)
以上のようにジヒドロジンセノサイ ド R b などのジンセノサイ ド類誘導体は、 ジンセノサイ ド R b iよりもかなり広い細胞外液濃度域で神経細胞のアポトーシス もしくはアポト一シス様神経細胞死を抑止することが in vitroの実験系で明らか にされたが、 実際に in vivoの実験系でもジヒドロジンセノサイ ド R b iなどのジ ンセノサイ ド類誘導体が、 ジンセノサイ ド R b iよりも広い投与用量域で神経細胞 保護作用を示すかどうかを本発明者は次にしらベた。 このため以下のごとく脳梗 塞ラッ 卜を用いて、 ジヒドロジンセノサイ ド R b iの静脈内投与実験を実施した。 約 1 2〜 1 6週齢の雄性 S H— S Pラッ ト (体重 2 8 0 — 3 2 0 g ) を使用し た。 同動物は 1 2時間ごとの明暗サイクル室で飼育し、 水ならびに餌は自由摂取 とした。 吸入麻酔下で同動物の左中大脳動脈皮質枝 (M C A) を凝固 ·切離した。 ジヒドロジンセノサイ ド R b を MCA永久閉塞直後に単回静脈内注入し ( 6 x g ) 、 その後アルザミニ浸透圧ポンプを用いて 2 4時間静脈内へ持続注入 ( 6. fi g Z 日) した (n = 6 ) 。 なお、 本実験手技の詳細については本発明者ら (阪中、 田 中) の既発表論文に記述されている (Igase K. et al. , J. Cerebr. Blood Flow Metab. , 19. 298-306, 1999) 。 As described above, ginsenoside derivatives such as dihydroginsenoside Rb can inhibit neuronal apoptosis or apoptosis-like neuronal death at a much higher extracellular fluid concentration range than ginsenoside Rbi. As revealed in an in vitro experimental system, in vivo experimental systems also show that ginsenoside derivatives such as dihydroginsenoside Rbi protect neurons in a wider dose range than ginsenoside Rbi The present inventor has investigated whether or not it has an effect. Therefore, an intravenous administration experiment of dihydroginsenoside Rbi was performed using a cerebral infarction rat as follows. Approximately 12- to 16-week-old male SH—SP rats (weight: 280—320 g) were used. The animals were housed in a 12-hour light / dark cycle room with free access to water and food. Under inhalation anesthesia, the left middle cerebral artery cortical branch (MCA) of the animal was coagulated and dissected. A single intravenous infusion of dihydroginsenoside Rb (6 xg) immediately after permanent MCA occlusion was followed by continuous infusion (6 fig g days) intravenously for 24 hours using an Alzamini osmotic pump. n = 6). The details of this experimental technique are described in published papers by the present inventors (Sakanaka and Tanaka) (Igase K. et al., J. Cerebr. Blood Flow Metab., 19.298- 306, 1999).
なお、 M C Aを永久閉塞した対照動物 (虚血コントロール動物) には同量の生 理食塩水 (v e h i c l e , 担体又は媒体) のみを静脈内投与した (n = 7 ) 。 M C A永久閉塞後 2 4時間目に、 致死量のペントバルピタールをラッ トの腹腔内 に注入した。 同動物が死亡した直後に脳を摘出し、 2 mmの厚みの前額切片を作 成した。 同切片を、 1 %の塩化 2 , 3, 5 —トリフエ二ルーテトラゾリゥム (2,
3, 5-triphenyl-tetrazolium chloride (TTC) ) 溶液に 3 0分間 3 7^:で 浸漬し、 1 0 %ホルマリンにて 1 2時間以上固定した。 結果を、 第 2 2図、 第 2 3図に示す。 第 2 2図は生理食塩水を投与した 2例を、 第 2 3図はジヒドロジン セノサイ ド R b を静脈内投与した 2例を示す。 Control animals in which MCA was permanently occluded (ischemic control animals) were intravenously administered only the same amount of physiological saline (vehicle, carrier or vehicle) (n = 7). At 24 hours after permanent MCA occlusion, a lethal dose of pentovalpital was intraperitoneally injected into the rat. Immediately after the animal died, the brain was removed and a 2 mm thick forehead section was prepared. The same section was prepared by adding 1% 2,3,5-chlorinated triphenyltetrazolium (2, The sample was immersed in a 3,5-triphenyl-tetrazolium chloride (TTC)) solution for 30 minutes at 37 ^: and fixed with 10% formalin for 12 hours or more. The results are shown in FIGS. 22 and 23. FIG. 22 shows two cases in which physiological saline was administered, and FIG. 23 shows two cases in which dihydrozine cenoside R b was intravenously administered.
第 2 2図に示すごとく、 MC A永久閉塞後生理食塩水を投与したラッ トでは、 向かって左側の大脳皮質に、 TT Cで染色されない白色の脳梗塞病巣が明らかに 認められた。 一方、 第 2 3図に示すごとく、 ジヒドロジンセノサイド R b iを MC A永久閉塞後に静脈内投与したラットでは脳梗塞病巣が顕著に縮小していた。 ジヒドロジンセノサイ ド R b ,を静脈内投与した脳梗塞ラッ ト (n= 6 ) の脳梗 塞面積と、 v e h i c l e (担体又は媒体) のみを投与した脳梗塞ラッ トの脳梗 塞面積 (n= 7) とを比較した。 結果を第 2 4図に示す。 第 2 4図に示すごとく v e h i c l e (生理食塩水) 投与脳梗塞群の脳梗塞面積に比べて、 ジヒドロ ジンセノサイ ド R b i ( 2 H- R b ι) 投与脳梗塞群の脳梗塞面積 ( i η ί a r c t a r e a) は 3分の 1程度に縮小していた。 統計解析法は M a n n— W h i t n e y Uテストにより、 * *印は Pく 0. 0 1を示す。 As shown in FIG. 22, in the rat to which saline was administered after permanent MCA occlusion, a white cerebral infarction lesion not stained with TTC was clearly observed in the left cerebral cortex. On the other hand, as shown in FIG. 23, cerebral infarction lesions were remarkably reduced in rats intravenously administered with dihydroginsenoside Rbi after permanent MCA occlusion. The cerebral infarction area of the cerebral infarction rat (n = 6) administered intravenously with dihydroginsenoside R b, and the cerebral infarction area of the cerebral infarction rat administered only vehicle (carrier or vehicle) (n = 7). The results are shown in FIG. As shown in Fig. 24, the cerebral infarction area of the group treated with dihydro ginsenoside R bi (2H-Rbι) was compared with the cerebral infarction area of the group treated with vehicle (saline). arctarea) was reduced to about one-third. In the statistical analysis method, the ** mark indicates P <0.01 by the Mann-WhitneyU test.
以上のことより、 ジヒドロジンセノサイ ド R b tの脳梗塞治療効果は、 WO 0 0 / 3 7 4 8 1号で開示されたジンセノサイド R b の効果に匹敵するほど優れたも のであることが判明した。 そこで本発明者はさらにジヒドロジンセノサイ ド R b の静脈内投与量を 2倍にして、 同様に脳梗塞治療効果が得られるかどうかをしら ベた所、 予想に反して優れた効果は認められなかった。 すなわち、 WO 0 0/ 3 7 48 1においてジンセノサイ ド R b は体重 3 0 0 g程度の S H— S Pラッ トに 対して 6 0 n gZ日の投与量でも優れた脳梗塞治療効果を示したが、 ジヒドロジ ンセノサイ ド R b はそのような高用量では必ずしも脳梗塞治療効果を発揮しない と考えられた。 From the above, it was found that the therapeutic effect of dihydroginsenoside Rbt on cerebral infarction was superior to the effect of ginsenoside Rb disclosed in WO 00/374841. did. Therefore, the present inventor further investigated whether or not the intravenous dose of dihydroginsenoside Rb was doubled and similarly obtained a therapeutic effect for cerebral infarction, and found that an unexpectedly superior effect was obtained. I couldn't. In other words, ginsenoside Rb showed an excellent therapeutic effect on cerebral infarction even at a dosage of 60 ng Z-day against SH-SP rat weighing about 300 g in WO 00/37481. However, it was considered that dihydrogensenoside Rb did not necessarily exert a therapeutic effect on cerebral infarction at such a high dose.
従って、 体重 3 0 0 g程度の脳梗塞ラッ トに対するジヒドロジンセノサイ ド R の至適投与量は、 ジンセノサイ ド R b の至適投与量よりも低く、 詳細には 6 0 g/日以下好ましくは 1 2 g/日以下と考えられた。 このことから、 培養 実験においてはジヒドロジンセノサイ ド Rb は、 ジンセノサイ ド Rb iよりも幅 広い濃度域で神経細胞のアポトーシスもしくはアポトーシス様神経細胞死を抑止
するが、 i n v i v oにおいてはジヒドロジンセノサイ ド R b は、 好ましくは ジンセノサイド R b よりも低い投与用量域で優れた脳梗塞治療効果を発揮すると 言える。 Therefore, the optimal dose of dihydroginsenoside R for a cerebral infarction rat with a body weight of about 300 g is lower than the optimal dose of ginsenoside Rb, and more preferably 60 g / day or less. Was considered to be less than 12 g / day. Thus, in culture experiments, dihydroginsenoside Rb inhibits neuronal apoptosis or apoptotic-like neuronal death in a wider concentration range than ginsenoside Rbi. However, in vivo, it can be said that dihydroginsenoside Rb exerts an excellent therapeutic effect on cerebral infarction preferably in a lower dose range than ginsenoside Rb.
これらのことから本発明のジヒドロキシジンセノサイ ド Rb 又はエポキシジン セノサイ ド R b iも同様な活性があることが示される。 ただし、 その投与量はジン セノサイ ド R b iとほぼ同量かそれ以上と考えられる。 実施例 2 2 (低用量ジヒドロジンセノサイ ド R b iの脊髄損傷治療効果判定実験) 本発明者らは、 さらに低用量のジヒドロジンセノサイ ド R b!が神経組織に好ま しい効果をもたらすことを確認するため、 ジヒドロジンセノサイ ド R b を 1. 2 ^ g/日の用量で脊髄損傷ラット (体重約 3 0 0 g) の静脈内へ 7日間持続注入 した。 ちなみに、 ジンセノサイ ド R b iを 6 0 g/日又は 1 2 g/日の用量で 脊髄損傷ラッ トの静脈内へ投与すると、 寝たきりの脊髄損傷ラットが起立するこ とを本発明者ら (阪中、 田中) は見出しているが (W 00 0/48 6 0 8号) 、 ジンセノサイ ド R b を体重 3 0 0 g程度の脊髄損傷ラッ 卜の治療に用いるときの 至適投与量は 6 0 gZ日であることを本発明者らは P CTZ J P 0 0/ 0 4 1 0 2号、 WO O 0 / 4 8 6 0 8号において明らかにしている。 These facts indicate that the dihydroxy ginsenoside Rb or the epoxide ginsenoside R bi of the present invention has a similar activity. However, the dose is considered to be about the same or more than that of ginsenoside Rbi. Example 22 (Experiment for judging therapeutic effect of low-dose dihydroginsenoside Rbi on treatment of spinal cord injury) The present inventors have found that dihydroginsenoside Rb! Dihydroginsenoside Rb at a dose of 1.2 ^ g / day intravenously in spinal cord injured rats (approximately 300 g body weight) for 7 days to confirm that has a favorable effect on nerve tissue. Continuous infusion was performed. The present inventors (Sakanaka, et al.) Found that administration of ginsenoside Rbi at a dose of 60 g / day or 12 g / day intravenously in spinal cord-injured rats raises bedridden spinal cord-injured rats. , Tanaka) (W 00 0/48 680), but the optimal dose when using ginsenoside Rb to treat spinal cord injury rats weighing about 300 g is 60 gZ. The present inventors have disclosed that this is the day in PCTZ JP 00/04102 and WO 0/46806.

A single infusion of bi (1.2 n) and intravenous dihydroginsenoside Rb! (1 day) was continuously administered for 7 days with an Alzamini osmotic pump. Control animals received the same amount of saline (vehicle, carrier or vehicle) on a similar schedule. The results are shown in FIGS. 25 and 26.
第 2 5図及び第 2 6図の左側写真は脊髄損傷後 2 日目の生理食塩水投与ラッ ト を、 第 2 5図及び第 2 6図の右側写真は、 同時期のジヒドロジンセノサイ ド R b 1 ( 1. 2 gZ日) 投与ラットを、 それぞれ示している。 第 2 5図及び第 2 6図 の左側写真に示すごとく、 下位胸髄に 2 0 gの圧力を 2 0分間負荷された生理食 塩水投与ラットは、 脊髄損傷当日のみならず、 脊髄損傷後 2日目にも両下肢の対 麻痺を呈した。 しかし下位胸髄に 2 0 gの圧力を 2 0分間負荷した後にジヒドロ
ド R b iを静脈内へ持続投与すると、 脊髄損傷当日は下肢の対麻痺を 呈していたが、 第 2 5図及び第 2 6図の右側写真に示すごとく脊髄損傷後 2 日 目 には、 両下肢の対麻痺が著しく改善し、 ラッ トは物につかまりながら立ち上がる ことができるようになった。 また、 ジヒ ドロジンセノサイ ド R b iを 1 6 g /日 又は 6 0 日の用量で脊髄損傷ラッ トの静脈内に投与しても優れた効果は認 められなかった。 The left photographs in Figs. 25 and 26 show the saline administration rats on the second day after spinal cord injury, and the right photographs in Figs. 25 and 26 show the dihydroginsenoside at the same time. Rats administered with Rb1 (1.2 gZ days) are shown. As shown in the left-hand photographs in Figs. 25 and 26, rats administered physiological saline with 20 g of pressure applied to the lower thoracic spinal cord for 20 minutes were treated not only on the day of spinal cord injury but also after spinal cord injury. He also had paraplegia on both legs on day one. However, after applying 20 g of pressure to the lower thoracic cord for 20 minutes, When R bi was continuously administered intravenously, paraplegia of the lower limbs was exhibited on the day of spinal cord injury.On the second day after spinal cord injury, as shown in the right photographs in Figs. Paraplegia in the lower limbs improved significantly, and the rat was able to stand up while holding onto an object. No superior effect was observed when dihydrozincenoside Rbi was administered intravenously to a spinal cord injury rat at a dose of 16 g / day or 60 days.
以上のことより、 ジヒ ドロジンセノサイ ド R b ジヒ ドロキシジンセノサイ ド R b 又はエポキシジンセノサイ ド R b などのジンセノサイ ド類誘導体は、 ジ ンセノサイ ド R b iと比較してもまったく遜色ないく らいに優れた脊髄損傷 · 頭部 外傷 · 神経外傷治療効果を発揮することが判明した。 しかも、 体重 3 0 0 gの脊 髄損傷ラッ トに対するジヒ ドロジンセノサイ ド R b の至適投与量は 1 . 2 a g / 日前後もしくはそれ以下と考えられた。 すなわち、 ジヒ ドロジンセノサイ ド R b tを神経外傷 · 頭部外傷 · 脊髄損傷治療用医薬組成物として利用するときは、 その 至適投与量はジンセノサイ ド R b iの 5 0分の 1前後又はそれ以下となることが発 明された。 前述のごとく、 ジヒ ドロジンセノサイ ド R b は、 高純度のジンセノサ イ ド R b!を原材料として 9 7 %の収率で作成することができるので、 ジヒ ドロジ ンセノサイ ド R b iは、 ジンセノサイ ド R b よりも効率良く、 神経外傷 · 脳卒中 など脳神経疾患の予防、 処置、 治療に利用され得ることになる。 ただし、 ジヒ ド ロキシジンセノサイ ド R b h 又はエポキシジンセノサイ ド R b tなどのジンセノ サイ ド類誘導体は、 ジンセノサイ ド R b iと同等もしくはそれよりも高い用量 · 濃 度域で前記疾患や病態に効果 · 効能を示すと考えられる。 実施例 2 3 (ジンセノサイ ド R b iによる水産動物の保護又は再生) From the above, ginsenoside derivatives such as dihydrozine senoside Rb and dihydroxyzine senoside Rb and epoxy ginsenoside Rb are not inferior to ginsenoside Rbi at all. Excellent spinal cord injury, head trauma, and nerve trauma were found to be effective. Furthermore, the optimal dose of dihydrozincenoside Rb for spinal cord injury rats weighing 300 g was considered to be around 1.2 ag / day or less. In other words, when dihydrozincenoside Rbt is used as a pharmaceutical composition for treating nerve trauma, head trauma, or spinal cord injury, the optimal dose is about one-fifth or less than that of ginsenoside Rbi. It was discovered. As mentioned above, dihydrozincenoside Rb is a high-purity ginsenoside Rb! Can be produced in 97% yield from raw material, so dihydridine senoside R bi is more efficient than ginsenoside R b and is used for prevention, treatment and treatment of cranial nerve diseases such as nerve trauma and stroke. You will get. However, Jinseno Sai de derivatives, such as dihydric de Loki hepcidin Seno Sai de R bh or epoxy ginsenosides Sai de R b t, the disease or condition in Jinsenosai de R bi is equal to or higher doses, concentrations range than It is considered to be effective. Example 23 (Protection or regeneration of aquatic animals by ginsenoside Rbi)
さて、 ジンセノサイ ド R b h ジヒ ドロジンセノサイ ド R b h ジヒ ドロキシジ ンセノサイ ド R b i又はエポキシジンセノサイ ド R b iは共通の効果、 効能、 用途 を有することがこれまで記述されてきたが、 次にこれら 4つの化合物のうちジン セノサイ ド R b を選び、 ジンセノサイ ド R b iが動物成長調整用組成物又は飼料 組成物となることを実験例に基づいて説明する。 このため、 動物としてたとえば 淡水魚である "夕ナゴ" を用いた実験例を以下に示す。
体長 3〜 5 c mの夕ナゴ (タイリクバラ夕ナゴ、 R h o d e u s o c e 1 1 a t u s o c e 1 1 a t u s ) 1 9匹を 2群に分け、 1 0匹は淡水 ( 5 ◦ リツ トル) のみにて 1 5 °C前後で 1 0 日間、 9匹はジンセノサイ ド R b i ( 1 0 0 f g /m l ) を含有する淡水中で同条件で 1 0日間飼育した。 その後、 すべての夕ナ ゴの尾びれ近傍の左側体表正中部に直径 2 m mの開放創を作成した。 開放創作成 には、 皮膚のバイオプシー用の器具 (トレパン) を用いた。 また、 開放創作成は、 淡水中のタナゴとジンセノサイ ド R b iを含有する淡水中の夕ナゴを交互に使用し て行い、 開放創作成直後にもとの水槽に夕ナゴを戻した。 開放創作成後、 8 日目 に生存している夕ナゴを観察した。 なお、 餌としてメダカ用の人工飼料を与えた。 ちなみに、 本タナゴの開放創は、 ヒトにたとえると大腿動脈の損傷 ·破裂を伴う 開放創に相当すると考える。 結果を第 2 7図、 第 2 8図、 第 2 9図に示す。 第 2 7図、 第 2 8図、 第 2 9図は図面に代わる写真である。 Now, it has been described that ginsenoside Rbh dihydrozincenoside Rbh dihydroxyzincenoside Rbi or epoxy ginsenoside Rbi has a common effect, efficacy, and application. Ginsenoside Rb is selected from the compounds, and it will be described based on experimental examples that ginsenoside Rbi is a composition for regulating animal growth or a feed composition. For this reason, an experimental example using the freshwater fish "Evening Nago" as an animal is shown below. Evening locust with a body length of 3 to 5 cm (Rhodeusoce 1 1 atusoce 11 1 atus) 1 9 animals are divided into 2 groups, and 10 animals are around 15 ° C only in fresh water (5 ° liter). For 10 days, 9 animals were bred in fresh water containing ginsenoside R bi (100 fg / ml) under the same conditions for 10 days. After that, open wounds with a diameter of 2 mm were created in the midline of the left body near the tail fins of all the locusts. An open wound was created using an instrument for skin biopsy (trepan). The open wound was created by alternately using a freshwater locust and a freshwater evening nago containing ginsenoside R bi, and returned to the original aquarium immediately after the creation of the open wound. On the 8th day after the creation of open wounds, surviving locusts were observed. In addition, artificial feed for medaka was given as bait. By the way, the open wound of this locust is considered to be equivalent to an open wound with damage and rupture of the femoral artery when compared to humans. The results are shown in FIGS. 27, 28, and 29. Fig. 27, Fig. 28 and Fig. 29 are photographs replacing the drawings.
第 2 7図の開放創作成直後の代表例に示すごとく、 1 9匹のタナゴすべてに直 径 2 mmの開放創を作成した。 開放創作成後 8日目には、 淡水のみで飼育した夕 ナゴは 1 0匹中 5匹がすでに死亡し、 生存していた 5'匹も第 2 8図に示すごとく、 ほとんどのもの (4匹) がほぼ尾ひれ部分を欠落していた。 一方、 ジンセノサイ ド R b i ( 1 0 0 f g/m 1 ) を含有する淡水中で飼育したタナゴは、 第 2 9図に 示すごとく開放創作成後 8 日目でも 9匹中 7匹が生存しており、 しかも生存して いる 7匹には尾ひれ部分 (すなわち開放創作成部よりも遠位部組織) の欠落はほ とんど認められなかった。 As shown in the representative example immediately after creation of the open wound in Fig. 27, open wounds with a diameter of 2 mm were created for all 19 locusts. On the 8th day after the creation of the open wound, 5 out of 10 locusts that had been reared in freshwater alone had died, and most of the surviving 5 ', as shown in Fig. Were almost missing the tail fin. On the other hand, as shown in Fig. 29, seven out of nine turkeys reared in freshwater containing ginsenoside R bi (100 fg / m In addition, seven surviving animals had little missing fins (ie, tissue distal to the open wound).
従って、 ジンセノサイ ド R b tは、 夕ナゴなどの水産動物を致死的な外傷、 血管損 傷、 創傷から守ることができると考えられる。 すなわち、 ジンセノサイ ド Rb iも しくはジンセノサイ ド R b iを含有する天然物は動物成長調整用組成物又は飼料組 成物として極めて有用であることが発明されたと言える。 Therefore, ginsenoside R bt is considered to be able to protect marine animals, such as eveningago, from fatal trauma, vascular injury, and wounds. In other words, it can be said that it has been invented that ginsenoside Rbi or a natural product containing ginsenoside Rbi is extremely useful as a composition for regulating animal growth or a feed composition.
