Abstract:
Aim To observe the protective effects and explore the possible mechanism of lycopene on hepatic injury induced by the combining use of isoniazid(INH) and rifampicin(RFP) in rats.Methods Chronic hepatic injury model was induced by INH and RFP.Low dosage,middle dosage and high dosage of lycopene(10,20,30 mg?kg-1 body weight) were given to protect liver injury.The serum level of AST and ALT,liver index,contents of malondialdehyde(MDA),glutathion(GSH) and superoxide dismutase(SOD) in liver were measured.Hepatic pathological changes were also observed after giving lycopene.Results Lycopene could reduce the liver index,the serum level of AST and ALT and the content of MDA,raise the liver GSH content and promote the activities of SOD in liver tissue in rats.Degeneration and necrosis of liver tissues were relieved.Conclusion Lycopene has protective effects on the hepatotoxicity in rats induced by the combination of INH and RFP for a long time,and the mechanisms is related to of antioxidation action of lycopene possibly.
