The resulting mixture is separated to obtain a supernatant frac~ion whi~h contains the pyridine-soluble extract and a pyridine residue~ Optionally, the pyridine:residue may be subjected to repea~ed separation procedures as described above using pyridine to remove furthex quantikies of the desired extract The pyridine is then removed from the ex~ract and the dried extract is dialyzed against a suitable liguid such as dis-tilled water. The absence of whole cells or cell fragment s contaminants is confirm~d by electron microscopy. The resulting purified extract may then be lyophilized by known methods to obta~n a stable product.
The pyridine-soluble extract produced in accordance with thi~ invention ~ay be combined with TDM and ACP to produce a composition having poten~ an~i-tumor activity without stimu-lating the induction of spleen and liver enlargements, The cancers which may be treate~ by this composition include animal tumor~ such as bovine squamous cell carcinoma, bovine fibro-sarcoma, equine sarcoid, equine melanoma, equine squamous cell carcinoma, canine mammary tumors, canine adenoma and canine melanoma and human tumors such as breast tumoes, lung tumors, colon tumors, malignant melanoma, squamous cell carcinomas and ovarian tumors.
The composition is preferably administered by injection in a pharmaceutically acceptable medium such as an oil-droplet emulsion directly into the tumor under conditions more partic-ularly described below. The aforesaid composition may be stab~ ed as,~or example, by a lyophilization procedure and ~h~n reconsti~ut~d without los5 of potency.
The amount of the p~ridine-soluble extract in a single lnjection for the treatment oE animals is between~about 375 and 2500 microqrams/milliliter. The amount of each of TDM and ACP
