The present study was made to investigate the protective effect of methanolic extract of Ficus benghalensis L., Moraceae, on isoniazid-rifampicin-induced hepatotoxicity in rats. Rats were divided into six different groups; group 1 served as a control, group 2 received isoniazid and rifampicin (100 mg/kg, i.p.), in sterile water, groups 3, 4 and 5 received 100, 200 & 300 mg/kg bw, p.o. methanolic extract of F. benghalensis and group 6 received Liv 52. All the treatment protocols followed 21 days and after rats were sacrificed blood and liver were used for biochemical and histological studies, respectively. Administration of isoniazid and rifampicin caused a significant elevation in the levels of liver marker enzymes (p

The present study was designed to evaluate the potency of antioxidant activity of sesame oil in-vitro model of myocardial ischemic reperfusion injury of rat. Sesame oil was administered orally to Wistar albino rats (180-200 g) in two different doses (n=6), by gastric gavage at a dose of 5 mL/kg b.w. (S1) and 10 mL/kg b.w (S2) daily for thirty days. Control and sesame oil treated rat hearts were subjected to invitro global ischemic reperfusion injury (5 min perfusion, 9 min noflow and 12 min reperfusion). A significant rise in TBARS and decrease of GSH, catalase, LDH, CK and AST occurred in the hearts subjected to in-vitro myocardial ischemic reperfusion injury indicate the myocardial damage through oxidative stress. In sesame oil treated rats there was a significant decrease in TBARS and significant increase in endogenous antioxidants and myocardial marker enzymes in all the groups. In 10 mL/kg treatment group, a significant rise in the levels of GSH, SOD and catalase were observed with marker enzymes, and it shows better recovery profile than the other groups subjected to in-vitro ischemic reperfusion injury. In histological studies, control rats which subjected to IR injury show extensive myocardial damage and all the treatment groups, shows preserved myocardium. The effect of sesame oil was compared with reference compound captopril. The present study demonstrates that the sesame oil treated by the dose 10 mL/kg augments endogenous antioxidant compounds of the rat heart and also prevents the myocardium from in-vitro model of myocardial ischemic reperfusion injury
