Abstract:
Objective:To explore the protective effect of the water-soluble total flavonoids from Isodon lophanthoides var.gerardia-nus (Benth.) H.Hara on LO2 cells damage.Methods:The cytotoxicity was evaluated by MTT cell viability determination to confirm the concentration range .Hepatocyte damage model was established by H 2 O2 treatment.After the oxidative stress hepatocyte was coin-cubated with WSTF at different concentrations for various times , the protective effect of WSTF on H 2 O2-induced hepatocyte damage was evaluated by MTT cell viability determination and the content determination of ALT , AST and MDA in cell supernatant .The inhibition of WSTF against H 2 O2-induced LO2 cells apoptosis was evaluated by the quantitative determination of Rhodamine 123 fluorescence and intracellular ROS.Results:The LO2 cells injured by 0.3 mmol· L-1 H2 O2 treatment for 4 h were used as the hepatocyte damage model.The concentration range of WSTF was 0.0312-0.125 mg· ml-1.WSTF could inhibit H2O2-induced injury in LO2 cells and obviously reduce ALT, AST and MDA.Moreover, WSTF could reverse mitochondrial membrane potential depolarization and decrease the amount of intracellular ROS .Conclusion:WSTF exhibits notable protective and curative effects on hepatocyte damage in vitro.
