ABSTRACT
AHCC (Active Hexose Correlated Compound) is an extract from mycelia of <i>Lentinula edodes, a mushroom</i> of the basidiomycetes family, which is cultivated in liquid media in a large tank. It is one of the most frequently used products in complementary and alternative medicine among cancer patients in Japan. Also in recent studies, it has been reported as efficacious in treatment of infectious and inflammatory diseases. AHCC has been proved as safe food by various safety evaluations and drug interaction studies have been conducted. The result of a Phase I trial in healthy volunteers concluded that AHCC is safe as a supplement in clinical practice. The present paper reviews the effects of AHCC in ameliorating the side effects of anti-cancer drugs, in modulating the immune system, in reducing inflammation and in infection prophylaxis.<br>
ABSTRACT
AHCC is a nutritional food that has been broadly adopted in Japan as well as other countries. Several laboratories have demonstrated that AHCC has immune modulating effect. Increasing immunity against bird flu virus, H5N1, may help to prevent the next pandemic. We hypothesize that uptaking AHCC improve immunity against infection with this virus. Administration of AHCC for 7 days effectively improved survival rate by 30%, and this effect can last for 3 to 4 weeks. Our results indicate a potential role of AHCC in helping to build up immunity for preventing the pandemic of bird flu.<br>
ABSTRACT
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.
