Liver toxicity was induced by combination of three antitubercular drugs [isoniazid(I) 7.5 mg/kg, rifampicin(R) 10 mg/kg and pyrazinamide(P) 35 mg/kg] given orally as suspension for 35 days in rats. The hepatoprotective activity was assessed using various biochemical parameters like aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatise(ALP), total bilirubin(TBL), albumin(ALB), total protein(TP), lactate dehydroginase(LDH), and serum cholesterol(CHL). Meanwhile,in vivoantioxidant activities as lipid peroxidation(LPO), reduced glutathione(GSH), superoxide dismutase(SOD) and catalase(CAT) were measured in rat liver homogenate. The biochemical observations were supplemented by histopathological examination.Results:The results demonstrated that treatment withS.xanthocarpumsignificantly(P<0.05-P<0.001) and dose-dependently prevented drug induced increase in serum levels of hepatic enzymes. Furthermore,S. xanthocarpumsignificantly(up toP<0.001) reduced the LPO in the liver tissue and restored activities of defence antioxidant enzymes GSH, SOD and CAT towards normal levels. Histopathology of the liver tissue showed that S. xanthocarpumattenuated the hepatocellular necrosis and led to reduction in inflammatory cells infiltration.Conclusions:The results of this study strongly indicate the protective effect of S. xanthocarpumagainst liver injury which may be attributed to its hepatoprotective activity, and thereby scientifically support its traditional use.展开更多
