AHCC (Active Hexose Correlated Compounds), which was at first extracted from cultured broth of Basidiomycotina, is known to be one of the Biological Response Modifiers (BRM). We examined the protective effects of AHCC on carbon tetrachloride (CCl4) and thioacetamide (TAA)-induced liver injury in mice. The AHCC pretreatment prevented the suppression of several physiological and biochemical parameters in the mice injected with CCl4 or TAA for 5 days. The liver weights and serum ALT and AST levels were increased by CCl4 or TAA, the degree of which was significantly reduced with the AHCC pretreatment. The AHCC pretreatment induced increasing activity of GST (glutathione s-transferase) and showed an increasing tendency of P450 and EROD (ethoxyresorufin o-dealkylation). The AHCC pretreatment also showed negative effects against the suppression of drug metabolizing enzymes, such as P450, EROD, and GST induced by CCl4 or TAA. AHCC pretreatment showed protective effects with significant inhibition of fatty change, inflammation, and necrosis in CCl4 and TAA intoxicated mice liver. The present study suggests that the protective effect of AHCC pretreatment might be related to the protection of liver from the drug induced liver injury in mice model.
