摘 要：Objective:To explore the hepatoprotective and antioxidant effects of piperine against acetaminophen-induced hepatotoxicity in ***:In mice,hepatotoxicity was induced by a single dose of acetaminophen(900 mg/kg b.w.i.p.).Piperine(25 mg/kg b.w.i.p.) and standard drug silymarin(25 mg/kg b.w.i.p.) were given to mice,30 min after the single injection of *** 4 h,the mice were *** of liver marker enzymes [(aspartate transaminase(AST),alanine transaminase(ALT),and alkaline phosphatase(ALP)]and inflammatory mediator tumour necrosis factor-alpha(TNF-α) were estimated in serum,while lipid peroxidation and antioxidant status(superoxide dismutase,catalase,glutathione peroxidase, glutathione reductase,glutathione-s-transferase and glutathione) were determined in liver homogenate of control and experimental ***:Acetaminophen induction(900 mg/kg b.w.i.p.) significantly increased the levels of liver marker enzymes,TNF-α,and lipid peroxidation,and caused the depletion of antioxidant *** and silymarin treatment to acetaminophen challenged mice resulted in decreased liver marker enzymes activity,TNF-αand lipid peroxidation levels with increase in antioxidant ***:The results clearly demonstrate that piperine shows promising hepatoprotective effect as comparable to standard drug silymarin.
