ABSTRACT
Aim To study the protective effect of total extract of astragalus(TEA) on primary rat hepatocytes injured by CCl4 or H2O2 and its mechanism.Methods The primary hepatocytes were isolated by Ⅳ collaganase and injured by CCl4 or H2O2.The contents of malondialdehyde(MDA) and glutathion(GSH),glutathion peroxidase(GSHpx) activity of hepatocytes and the AST and /or ALT level in cultural supernatant were determined by general methods. Results (1) The elevation of MDA content of hepatocytes and AST level in supernatant of cultural hepatocytes,and the loss of GSH content and GSHpx activity induced by CCl4 were restored remarkably by TEA(5~80 mg?L-1);(2)The elevation of ALT level in the supernatant of hepatocytes and MDA content of hepatocytes, and the loss of GSH content and GSHpx activity induced by H2O2 were improved significantly by TEA(5~80 mg?L-1) treatment.Conclusion The results suggest that TEA possess direct protective action on primary hepatocyte in vitro injured by CCl4 or H2O2. These might be associated with its anti-oxidative activity.
