Abstract:
Objective To investigate the protective function of oxymatrine on the renal intestitial fibrosis in rats.Methods Forty male Sprague Dawley rats were randomly divided into 5 groups: sham group,model group,Lotensin group,large-dose oxymatrine group,and small-dose oxymatrine group.The models were established by unilateral ureteral obstruction(UUO) of the left side.On the 14~(th) day after operation,the obstructed kidney was taken out.Then,HE,Massion,and immunohistochemistry staining of transforming growth factor-?_(1)(TGF-?_(1)),(?-smooth) muscle acting(?-SMA) and collagen Ⅲ were conducted.After that,semiquantitative analysis was performed.Results After oxymatrine,treatment,the expressions of ?-SMA,TGF-?_(1) and ColⅢ of the obstructed kidney in the treatment group were significantly lower than those in the model group(P0.05).Conclusion Oxymatrine may reduce the expression of cytokines such as TGF-?_(1),then the activation of cell producing ECM and then the sendimentation of ECM,thus preventing renal interstitial fibrosis.
