Objectives : This study was undertaken to determine if a combined(SPe) has a protective effect against functional failure induced by $CCl_4$ in rat liver. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to rats and data were obtained. Liver injury was estimated by measuring aspartate aminotransferase(AST) and alanine aminotransferase(ALT) activity in serum. Lipid peroxidation was examined by measuring malondialdehyde, a product of lipid peroxidation. GSH activities in liver tissues were also measured. Results : When rats were treated intraperitoneally with $CCl_4$, serum AST and ALT were increased compared with the control, which was significantly inhibited by pretreatment of SPe. SPe also prevented reduction in GSH induced by $CCl_4$. Conclusion : Above results suggest that SPe exerts protective effect against $CCl_4$ by its antioxidant action in liver tissues. Thus, SPe may be used in prevention and treatment of drug-induced liver cell injury. However, the precise mechanisms of SPe protection remain to be determined.
