Abstract:Objective To observe the liver protection of Ginsenoside Rg1 and Oxymatrine and research its mechanisms.Methods Nonalcoholic fatty liver disease(NAFLD) model was induced by high-fat diet and hepatic fibrosis(HF) model was caused by CCl4 in rats. Protection effects of Ginsenoside Rg1, Oxymatrine and the combination were obsrved.ResultsBoth Rg1 and OMT significantly reduced serum total cholesterol(TC), triglyceride(TG), alanine aminotransferase(ALT) and aspartate amino transferase (AST) levels of NAFLD ratsRg1 group (2.76±0.22) mmol/L,(1.24±0.17) mmol/L,(112.39±12.91)U/L, (195.16±12.99) U/L; OMT group (2.35±0.19) mmol/L,(1.09±0.09) mmol/L,(90.57±10.25) U/L, (186.45±13.14) U/L,P〈0.05 or 0.01],elevated liver PPARα mRNA and PPARγ mRNARg1 group: (0.64± 0.05),(0.77±0.07);OMT group(0.67±0.07),(0.73±0.06),P〈0.05 or 0.01] and alleviated the degree of fatty liver. The effects of the combination group(1.87±0.21) mmol/L, (0.77±0.10) mmol/L,(58.78± 8.87)U/L,(149.78±11.27)U/L,(0.81±0.09),(0.89±0.05) ] was better than single treatment group (P〈0.05 or 0.01). Both Rg1 and OMT significantly reduced the serum ALT, AST levels and liver methane dicarboxylic aldehyde(MDA)contentRg1 group: (46.75±5.11) U/L,(147.53±7.31) U/L,(5.54±1.06) nmol/g; OMT group:(148.24±4.32) U/L, (93.90±14.22) U/L,(5.85±0.91) nmol/g,P〈0.01] in HF modelRg1 group: (146.75±5.11) U/L,(147.53±7.31)U/L,(5.54±1.06)nmol/g; OMT group:(148.24±4.32) U/L,(93.90±14.22) U/L,(5.85±0.91) nmol/g,P〈0.01], enhanced liver SOD activityRg1 group:(91.61±9.26) U/mg prot; OM group: (86.19±8.51) U/mg prot,P〈0.01] and reduced the semi-quantitative score Rg1 group:(2.7±0.4); OMT group:(2.9±0.5),P〈0.05 or 0.01], the effect of the combination group(92.21±4.36) U/L,(52.08±7.56) U/L,(3.68±0.54) nmol/g,(99.67±13.13) U/mg prot, (1.2
