Effects of matrine on acetaminophen-induced liver injury
Objective To investigate the mechanism of matrine hydrochloride injection on acetaminophen(APAP)induced liver injury in mice.Methods Sixty male Kunming mice were randomly divided into blank group,model group and experimental-L,-M,-H groups.The mice were abdominal injected 300 mg·kg-1 APAP to build the acute liver injury modeling.The experimental-L,-M,-H groups were intravenous injected matrine of 0.7,1.4,and 2.8 mg·kg-1,respectively.Blank and model groups were injected with 10%glucose solution 10 mL·kg-1·d-1 via tail vein.Enzyme-linked immunosorbent assay were used to measure the levels of glutamic oxaloacetic transaminase(GOT),glutamic oxaloacetic transaminase(GPT),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in mice serum.The kit were employed to detect the levels of superoxide dismutase(SOD)and malondialdehyde(MDA)in liver tissue.Results The serum GOT levels in the experimental-M,-H groups,model group and blank group were(5 593.45±128.46),(2 316.24±125.37),(8 302.16±267.15)and(40.13±7.69)U·L-1;the GPT levels were(6 159.37±129.64),(2 597.10±120.37),(8 1699.54±259.87)and(36.47±9.46)U·L-1;the IL-6 levels were(159.43±26.42),(96.37±25.84),(215.34±47.68)and(83.72±26.37)pg·mL-1;the TNF-α levels were(327.68±38.37),(249.69±44.97),(477.68±58.59)and(254.35±50.67)pg·mL-1;the SOD levels were(329.46±37.49),(371.16±33.76),(246.84±38.79)and(429.67±23.76)U·mg-1;the MDA levels were(5.34±0.76),(4.09±0.54),(12.46±3.76)and(3.12±0.42)nmol·mg-1.There were significant differences between the experimental-M,-H groups and the model group(all P<0.05).Conclusion Matrine has a significant protective effect on APAP induced drug-induced liver injury,and its protective mechanism is related to inhibiting inflammatory response and alleviating oxidative stress response.
