    Abstract:
    This study was undertaken to investigate the protective effects of Phyllanthus emblica Linn. (PE) extract on ethanol induced rat hepatic injury. PE (0.5 and 1 mg/ml) increased cell viability of rat primary cultured hepatocytes being treated with ethanol (96 microl/m) by increasing % MTT and decreasing the release of transaminase. Hepatotoxic markers studied in rats included serum transaminases (AST and ALT), serum triglyceride (STG), hepatic triglyceride (HTG), TNF-alpha and IL-1beta together with histopathological examination. Pretreatment of rats with PE at oral dose of 25, 50 and 75 mg/kg or SL (silymarin, a reference hepatoprotective agent) at 5 mg/kg, 4 h before ethanol, lowered the ethanol induced levels of AST, ALT and IL-1beta. The 75 mg/kg PE dose gave the best result similar to SL. Treatment of rats with PE (75 mg/kg/day) or SL (5 mg/kg/day) for 7 days after 21 days with ethanol (4 g/kg/day, p.o.) enhanced liver cell recovery by bringing the levels of AST, ALT, IL-1beta back to normal. Histopathological studies confirmed the beneficial roles of PE and SL against ethanol induced liver injury in rats.
