Effect of ginseng polysaccharide fraction was examined for $CCl_4$-induced hepatotoxicity in vitro and in vivo. In $CCl_4$-injured primary cultured rat hepatocytes, treatment of the polysaccharide fraction (0.1, 0.3, 1.0 mg/ml) significantly Inhibited the release of LDH and GOT into the culture medium in a dose-dependent manner. Oral administration of the polysaccharide fraction (100, 200 mg/kg) inhibited the decrease of body weight and the increase of the ratio of liver to body weight in $CCl_4$-intoxicated rats. Elevation of GOT, GPT and ALP activity in the serum by $CCl_4$-induced hepatotoxicity was suppressed by administration of ginseng polysaccharide fraction. MDA levels increased in the serum as well as in the liver tissue by treatment with $CCl_4$ showed a tendency to be 연w in the rats given to the polysaccharide fraction. These results suggest that the polysaccharide fraction may be active substance responsible for antihepatotoxic effect of Panax ginseng.
