Protective effect of Sida cordata leaf extract against CCl4 induced acute liver toxicity in rats

摘要

Objective: To investigate the hepatoprotective potential of Sida cordata (Malvaceae) (S. cordata) in experimental rats to validate its traditional claim. Methods: Wister albino rats were divided into 6 groups: Group Ⅰ served as control; Group Ⅱ served as hepatotoxic (CCl4 treated) group;Group Ⅲ, Ⅳ and Ⅴ served as (100, 200 and 400 mg/kg b.w.) S. cordata leaf extract (SCLE) treated groups; Group Ⅵ served as positive control (Silymarin) treated group. Liver marker enzymes serum glutamate oxyloacetic transaminase, serum glutamic pyruvic transaminase, pancreatic enzymatic antioxidants superoxide dismutase (SOD), lipid peroxidation, catalase (CAT), reduced glutathione (GSH) were measured and compared along with histopathological studies. Results:Obtained results show that the treatment with SCLE significantly (P<0.05-<0.001) and dose-dependently reduced CCl4 induced elevated serum level of hepatic enzymes. Furthermore, SCLE significantly (up to P<0.001) reduced the lipid peroxidation in the liver tissue and restored activities of defence antioxidant enzymes GSH, SOD and CAT towards normal levels, which was confirmed by the histopathological studies. Conclusions: The results of this study strongly indicate the protective effect of SCLE against CCl4 induced acute liver toxicity in rats and thereby scientifically support its traditional use.
