Abstract:
Objective:To study the effect of Lycium Barbarum Polysaccharide(LBP) on the activity and gene expression of hepatocyte cytochrome P4503A(CYP3A) in rat model with alcoholic fatty liver (AFL). Methods:The AFL rats models were established by ethanol intragastric infusion for ten weeks. Then,those AFL model rats were treated with 5% and 10% LBP and 10% GSH intragastric infusion. Liver pathologic changes were observed and the activity of CYP3A and its gene expression as well as the contents of malondialdehyde(MDA) and glutathione(GSH) in liver were detected and compared among the control group,treatment group and abstinence treatment group. Results:Fatty degeneration in liver recovered normally in the LBP treatment groups. LBP could inhibit the expression of CYP3A gene,reduce the activity of CYP3A and the content of MDA,and increase the content of GSH. The curative effect of LBP was not significantly different from that of GSH,but greater than that of abstinence treatment. Conclusion:LBP can prevent AFL through markedly inhibiting the hepatocyte CYP3A activity and gene expression.
