AbstractObjectivesThe main objective of the present study is to evaluate the mitigative effect of hydroalcoholic extract of Momordica cymbalaria fruits against sodium fluoride (NaF) induced hepatotoxicity.MethodsIn this study, Wistar male albino rats were randomly divided into five groups of six rats each. Group I and II served as normal and toxic controls. Group III as plant control received extract at a dose of 400 mg/kg b. wt, p.o and Groups IV and V as treatment groups received extract at a dose 200 and 400 mg/kg b. wt, p.o for 30 days. All groups except Groups I and III received 100 ppm of NaF through drinking water. After completion of the study, blood collected for the estimation of liver blood serum biomarkers such as aspartate aminotransferases (AST), alanine aminotransferases (ALT), alkaline Phosphatase (ALP), direct and total bilirubin, total protein and albumin. The liver tissue homogenate was for estimation of lipid peroxidation, catalase, and reduced glutathione levels.ResultsThe results showed that NaF intoxication caused elevation of liver blood serum levels and lipid peroxidation; decreased levels of serum total protein, albumin and liver reduced glutathione, and catalase observed. The treatment groups showed decreased elevated serum biomarkers (ALT, AST, and ALP), liver lipid peroxidation and increased serum total protein and albumin, liver reduced glutathione and catalase levels in a dose-dependent manner. Histopathological studies also further strongly supported for mitigative effects of the plant.ConclusionsIn conclusion, our findings of the study indicated that M. cymbalaria fruits were a potential drug candidate in the treatment of NaF induced hepatotoxicity.

INTRODUCTION: The present study evaluated the modulatory effects of diphenylhydrazine induced experimental wistar albino rats and also to assess various biochemical parameters in whole blood and red blood cell lysate.MATERIALAND METHODS: Twenty male albino rats weighing 180-200 gm were selected for the study and divided in two groups; ten phenylhydrazine dihydrochloride (PHZ) induced anemia and ten healthy control. Thiobarbituric acid reactive substances and lipid hydroperoxide were measured as lipid peroxidation parameter. The antioxidant vitamins A, C and E and enzymatic antioxidants; catalase, glutathione peroxidase and superoxide dismutase were also assessed.RESULTS: Phenylhydrazine induced anemic rats showed a significant increase in the lipid peroxidation and decrease in the antioxidants as compared to healthy rats.CONCLUSION: The study concludes that phenylhydrazine induced experimental anemic albino rats showed increased oxidative stress than compared with healthy albino rats.Journal of Universal College of Medical Sciences Vol. 3, No. 1, 2015: 41-47

Groups of adult male frogs were force fed on diets either devoid of fat and tocopherols or containing "stripped" corn oil with or without added α-tocopherol for 120 days. At the end of this period histological examinations of the gastrocnemius muscles and testes revealed no signs of degeneration in any dietary group. Biochemical studies on the muscle gave no reflection of tocopherol deficiency in the levels or proportions of total ribonucleic acid and deoxyribonucleic acid but did show a marked lowering of total muscle creatine in frogs on the tocopherol-free diets. The deficient animals subjected to considerable amounts of the polyunsaturated corn oil exhibited the lowest creatine levels. It is concluded that the adult frog has a dietary requirement for vitamin E and that more prolonged deprivation probably would result in the dystrophic symptoms commonly noted in other species.
