Abstract:
Objective:To study the effect of Lycium Barbarum Pclysaccharide(LBP)on the expression of hepatocyte cytochrome P4502E1(CYP2E1) in rat model of alcoholic fatty liver(AFL).Methods: The AFL rats models were established by ethanol intragastric infusion in ten weeks,then,5% and 10% LBP and 10% GSH intragastric infusions were adopted to treat those AFL model rats.Liver pathologic changes were observed and CYP2E1 gene and protein expressions as well as the contents of malondialdehyde(MDA) and glutathione(GSH) in liver were detected and compared with those in the control group,treatment groups and abstinence treatment group.Results: Fatty degeneration in liver recovered normally in the LBP-treated groups.LBP could inhibit the expressions of CYP2E1 gene and protein,reduce the content of MDA,and increase the content of GSH.The curative effect of LBP was of no significant difference compared with GSH,but had more effect than abstinence treatment.Conclusion: LBP can prevent AFL though inhibiting the hepatocyte CYP2E1 expression markedly.
