The Experimental Study on Liqihuatanquyu Formula(LF)Against NASH in Rats / 医学研究杂志

ABSTRACT

Objective To investigate the effect of LF on blood biochemistry,cytokines in rats with NASH in order to approach possible mechanism of LF against NASH.Methods 50 male SD rats were randomly divided into the normal control group(10 rats),the model group(10 rats),the Essentinale group(10 rats)、the LF high dose group(10 rats)and the LF low dose group(10 rats).Except for the normal control group which was raised by standard animal feeds,others were all raised by high fat feeds to make NASH model and administered by Essentinale,high dose LF and low dose LF for 12 weeks.Hepatic lipid contents,plasma TG,CHO,HDL-C,LDL-C,ALT,AST and TNF-?,FFA,Leptin concentrations were evaluated,as were histopathological changes in the liver.Results In this NASH model,the liver FZ(liver weight /body weight),plasma CHO,LDL-C,ALT,AST and TNF-?,FFA,Leptin concentrations were higher than that in normal control group,but the levels of serum HDL-C and TG were reduced.In addition,the histopathological showed increased fatty droplets within hepatocytes and liver inflammation.The levels of serum ALT,AST,HDL-C,TNF-?,Leptin,FFA and hepatic CHO,TG contents in the LF high dose group and LF low dose group were reduced compared with that in the model group,while the levels of serum TG,HDL-C were enhanced remarkably.In addition,liver inflammation was improved evidently.Conclusions Treatment with LF might improve non-alcholic steatohepatitis,because LF inhibits the elevation in the level of plasma cytokine.
