This study was carried out to determine whether Kamihaengche-tang plus Yukmijihwang-tang (KCYH) exerts the protective effect against oxidant-induced liver cell injury. Cell injurt was estimated by measuring lactate dehydrogenase (LDH) and alanine aminotransferase (ALT) release, and lipid peroxidation was estimated by measuring malondialdehyde, a product of lipid peroxidation in rabbit liver slices. $H_2O_2$increased LDH release which was significantly prevented by 1% KCYHT. The protective effect of KCYH against $H_2O_2$-induced cell injury was dose-dependent in the range of 0.05-1% concentrations. Similary, KCYH inhibited $H_2O_2$ induced lipid peroxidation in a dose-dependent manner. When liver tissuse were exposed to Hg(0.5 mM), ALT activity in the medium and lipid erpoxidation in tissues were markedly increased. These changes were prevented by 1% KCYH. KCHY restored Hg-induced inhibition of cellular GSH content. These result indicate that KCYH exerts the protective effect oxidant-induced liver cell injury, and this effect is attributed to prevented to prevention of lipid peroxidation. These dffects may be due to an increase in concentration of endogenous antioxidants.
