Abstract:
Aim To investigate the the effect of ginsenosides of stem and leaf(GSL) on mouse fatty liver and its mechanism.Methods Mice were randomly divided into normal control group(NC,fed with normal diet) and model group(fed with high-fat diet).Twelve weeks later,when the establishment of experimental model of fatty liver was confirmed,the model mice were subdivided into 4 subgroups: HF group(fed continuously with high-fat deit),NT group(fed with normal deit),GSL1 group(fed with normal deit and treated intragastrically with GSL 50 mg?kg-1?d-1),GSL2 group(fed with normal deit and treated intragastrically with GSL 100 mg?kg-1?d-1).Mice in NC,HF and HT groups were given distilled water by gastric perfusion.Two weeks later,all mice were killed,and blood was collected for measuring serum TC,TG,HDL-C,LDL-C,ALT contents,liver tissue for determining hepatic TC,TG,MDA SOD levels.In addition,liver index and pathology were also observed.Expression of PPAR? and CYP2E1 mRNA in liver was examined by RT-PCR.Results In GSL2 group,GSL significantly reduced liver index,serum lipid,hepatic lipid and MDA contents,and elevated SOD activity.Moreover,GSL obviously improved pathological change,increased PPAR? mRNA and suppressed CYP2E1 mRNA levels in the liver.In NT group,hepatic lipid and MDA contents remained high and SOD activity is low,although liver histology somewhat improved.In GSL1 group the results were similar to those in NT group.Conclusions These results suggest that GSL might be effective in the treatment of hepatic adipose infiltration of mice.It may be associated with increasing PPAR? mRNA,then decreasing serum lipid and hepatic lipid;and inhibiting CYP2E1 mRNA expression in the liver,thus suppressing lipid peroxidation.
