Suppressive Effect of Tritoqualine on Enzyme Leakage Induced by D-Galactosamine in Rat Primary-Cultured Hepatocytes

[摘要] References(9)Cited-By(2)Tritoqualine (TRQ) was previously reported to suppress enzyme leakage and lipid peroxidation induced by carbon tetrachloride in isolated hepatocytes. In the present study, we investigated the effect of TRQ on enzyme leakage from rat primary-cultured hepatocytes using D-galactosamine (GaIN) which causes hepatic injury without lipid peroxidation. Leakage of GPT and GPT was significantly increased at 18 hr after GaIN addition, being saturated at 42-50 hr. This enzyme leakage was suppressed dose-dependently by TRQ at 42 hr, but not by vitamin E. These results suggest that TRQ shows a suppressive effect on enzyme leakage from hepatocytes independently of its inhibitory action on lipid peroxidation.
