				        	Objective To study the protective effects of garlic polysaecharide on L02 from oxidative injury.Methods Cultured L02 were injured by ethanol.Various concentrations of GP(10、20、40、80 mg/L) were added into culture medium.Then the cellular MDA,SOD,and GSH-Px were determined in order to observe the protection of curcumin and the time-dose-response effects.Meanwhile,HO-1 mRNA was detected by RT-PCR method after ethanol exposure.The expressions of HO- 1 proteins were detected by Western blotling.Results GP (10、20、40、80 mg/L) could reduce oxidative injury induced by ethanol in L02 cells.Liver cells were 100 mmol/L alcohol after 8h exposure,SOD[(3.65±0.42) NU/mg,(4.11±0.16) NU/mg,(4.61 ±0.23)NU/mg],GSH-Px [ (75.96 ± 8.96) mg/mg,(81.83±5.70) mg/mg,(89.32±6.35) mg/mg respectively],GSH-Px[(75.96±8.96),(81.83±5.70),(89.32±6.35) respectively]activity,MDA[(1.05±0.16) nmol/mg,(0.99± 0.12) nmol/mg; (0.78± 0.11) nmol/mg respectively]levels compared with the control group [ (2.35 ±0.28) NU/mg,(54.41 ±8.17) mg/mg,(1.58±0.23) nmol/mg respectively],there was a significant difference (P< 0.05 ); HO-1 mRNA expression was in a concentration- dependent effect.Conclusion GP had protective effects on L02 from oxidative injury probably by reducing GSH consumption,improving antioxidant enzyme activity and inhibiting lipid peroxidation reaction at dose-dependent manner.GP could promote expression of HO-1 mRNA co-coordinating role in protecting liver cells from oxidative injury.
