The present experiment was perf’3rmed to investigate the protective effects of ginseng total saponin (GTS) and possible mechanisms on the hepatocytotoxicity induced by tert-butylhydroperoxide (t-BuOOH), 4-Bromo-calciumu ionophore A23187 (Br-A23187) and KCN. Hepatocytes were isolated by collagenase perfusion of livers from fasted male Sprague Dawley rats and cultured overnight. After various treatments in Krebs-Ringer-HEPES buffer at pH 7.4, cell viability was determined by propidium iodide using fluorocytometry. GTS (5-20 μM) inhibited cell killing induced by t-BuOOH, and KCN, dose-dependently. However, GTS did not inhibit Br-A23187-induced cell killing. These findings support that GTS could protect the hepatocytoxicity induced by some toxic chemicals. The mechanisms of these protective effects by GTS seem to be associated with antioxidant activity and increase of cellular ATP.
