In order to examine the effect of Injinhotang extract on the liver cancer induced by N-nitrosodiethylamine (NDEA) and carbon tetrachloride (CCl4) in Rats. The animals were divided into three groups. The normal (Nor) group were fed basal diet. Control (Con) group were administered with NDEA (200 mg/kgb.w., i.p.) and CCl4. Injinhotang extract (IJH) group treated with Injinhotang extract (260 mg/kg/day) for 8 weeks after NDEA+CCl4. Enzymic antioxidants, such as superoxide dismutase (SOD) and catalase levels were determined in all the groups of animals. The activities of SOD were significantly increased in the Con, but the activities of catalase were decreased in the Con, but the anti-oxidative enzyme activities of superoxide dismutase and catalase were increased in the IJH. In the immunohistochemistry observation, treatment of Injinhotang extract reduced the rates of p53 immunoreactivity. According to the electron microscopical observation, in the liver cancer cells were increased the smooth endoplasmic reticulum and dilated the rough endoplasmic reticulum in the Con compared with IJH. These results suggest that administration of Injinhotang extract suppress or retard NDEA and CCl4-induced liver cancer.
