Abstract:
Objective:To study the effect of compound Biejiaruangan tablets on the expression of liver AngiotensionII and its receptor in rats with hepatic fibrosis,and to explore the mechanism of its anti-hepatic fibrosis.Methods: Thirty male SD rats were randomly divided into three groups as followings: the normal group,the model group and the compound Biejiaruangan tablets group,all rats in the two latter groups were given subcutaneous injection of 40%carbon tetrachloride(twice every week for 6 weeks),the rats in the compound Biejiaruangan tablets group were given 1g?kg-1?d-1 of the compound Biejiaruangan tablets by daily gavage,the rats in normal control group and the model group were given distilled water according to the same volume,the histopathological changes in liver were observed through HE and Massion staining.The serum ALT,AST and ALP were evaluated by antomatic biochemistry analysator,the serum levels of hyaluronic acid (HA),Laminin(LN) and plasm AngiotensionII(Ang-Ⅱ) were determined by radio immunoassay.The expressions of AngⅡ,AT1R mRNA were examined by RT-PCR.Results:The severity of inflammation scoring,hepatic fibrosis scoring,the amounts of serum ALT,AST,ALP,HA,LN and plasma AngⅡ in the liver tissues of hepatic fibrosis model group were higher than those in the normal group(P
