Abstract

Background and Objectives: appendicitis is a common urgent surgical operation. Since early diagnosis and treatment of appendicitis is necessary and also some disease mimic its clinical manifestation and rate of negative appendectomy was high (%30-15), so surgeons were trying to increase the accuracy of diagnosis of appendicitis by using laboratory facilities. The main aim of this study was to investigation of sensitivity and specificity CRP in the diagnosis of acute appendicitis and compares it with routine laboratory tests such as leukocyte count and neutrophil count.
Methods: In this descriptive - analytical study, blood samples of 191 patients with diagnosis of acute appendicitis that underwent appendectomy at the Besat hospital, were used to measuring of CRP. The surgical specimens were reviewed by pathologists and pathologic findings were considered as gold standard. Then by using of the results of pathology tests, sensitivity, specificity and positive and negative predictive value of CRP, WBC and neutrophils were measured. Data were analyzed by SPSS14.0 software and t test and chi square test.
Results: about 74 percent of the patients were male and 25.7% were female and the mean age was 26 ±3.4 years. The most common symptom, sign and pathologic stage of patients were loss of appetite (95.2%), local tenderness (95.8%) and Acute suppurative 64.9%. about thirteen percent of patients had normal appendectomies that consist of 35% of women and 6% of men appendectomy. The sensitivity and specificity of CRP, WBC and neutrophils respectively were: 93.3%, 50%, 84.8%, 61.5%, 98.1% and 19.2%.
Conclusion: According to the results, the CRP test at diagnosis and in finding of negative appendectomy has high value, but was not reliable as an exclusive test. Therefore, the use of CRP as a paraclinical criterion along with other criteria of Alvarado scoring system can be very useful in diagnosis of appendicitis.

Abstract

Background and Objectives: fluoride in low concentration is essential for human but in high concentration is very hazardous for human health. The efficacy of Snail Shell (SS) was investigated in this research work as an adsorbent for the elimination of fluoride from aqueous.
Methods
: in this experimental study, the capability of SS to adsorb fluoride ions was conducted using a series of batch tests in a shaker-incubator instrument. For each batch run, 100 mL of solution containing a known initial concentration of Fluoride and with the preferred level of pH was shacked. The effects of selected parameters such as pH (3-11), reaction time (5–60 min) cyanide concentrations (5-10 mg/L) and the adsorbent dosage (0.25–2.5g/L) were investigated on the removal fluoride as a target contaminate. Chemical composition SS were analyzed using a Philips model XL30- scanning electron microscope (SEM) with energy-dispersive X-ray microanalysis (EDX). The concentration of Fluoride in solution before and after treatment was determined using the HACH method.
Results
: Analysis of the SS component using the EDX technique showed that the main part of it consisted of calcium and its other components were magnesium, aluminum and silicate. The experimental data showed that the maximum fluoride removal occurred at pH of 7, adsorbent dose (0.5 g/L) and 30 min contact time and 5 mg/lit initial concentration. The kinetic evaluation indicated that the pseudo-second-order kinetic had the best fit to the experimental results predicting a chemisorption process. The equilibrium adsorption of fluoride onto SS was well represented by the Langmuir equation.
Conclusion: As a result, SS was revealed as a very efficient and low-cost adsorbent and a promising option for removing fluoride from industrial wastewaters.

Abstract

Background and Objectives: cyanides as carbon-nitrogen radicals are very toxic compounds and highly harmful to humans and aquatic organisms. The efficacy of eggshells (ES) was investigated in this research work as an adsorbent for the elimination of cyanide from polluted streams.
Methods: In this experimental study, the capability of ES to adsorb cyanide ions was conducted using a series of batch tests in a shaker-incubator instrument. For each batch run, 100 mL of solution containing a known initial concentration of cyanide and with the preferred level of pH was shacked. The effects of selected parameters such as pH (11-3), reaction time (60–5 min) cyanide concentrations (150–50 mg/L) and the adsorbent dosage (2–0.25 g/L) were investigated on the removal cyanide as a target contaminate. Chemical composition ES were analyzed using a Philips model XL- 30 scanning electron microscope (SEM) with energy-dispersive X-ray microanalysis (EDX). The specific surface and pore size distributions of ES were measured via Brunauer-Emmett-Teller (BET) isotherm and Barrett-Joyner-Halenda (BJH) methods using a Micrometrics particle size analyzer. The concentration of cyanide in solution before and after treatment was determined using the titrimetric method as described in the standard methods.
Results: Analysis of the ES component using the EDX technique showed that the main part of it consisted of calcium and its other components were magnesium, iron, aluminum and silicate. The experimental data showed that the maximum cyanide removal occurred at pH of 11, adsorbent dose (0.5 g/L) and 40 min contact time. The kinetic evaluation indicated that the pseudo-second-order kinetic had the best fit to the experimental results predicting a chemisorptions process. The equilibrium adsorption of cyanide onto ES was well represented by the Langmuir equation.
Conclusions: As a result, ES as waste materials was revealed as a very efficient and low-cost adsorbent and a promising option for removing cyanide from industrial wastewaters.
