黄芩苷对UUO大鼠肾间质纤维化的影响及可能机制
Effects and possible mechanism of baicalin on renal interstitial fibrosis in unilateral urethral obstruction rat
摘要
Abstract
Objective To explore the effects and possible mechanism of baicalin on renal interstitial fibrosis in unilateral urethral obstruction (UUO) rat.Methods Forty male SD rats were randomly divided into the sham operation group,model group,baicalin group,benazepril group and baicalin+ benazepril group,8 rats in each group.The baicalin group received the gavage of baicalin 40 mg · kg-1 · d 1,the benazepril group received the gavage of benazepril suspension 10 mg · kg-1 · d-1,the rats baicalin+ benazepril group received the gavage of baicalin 40 mg · kg-1 · d 1 and benazepril suspension 10 mg · kg-1 · d-1,the model group and sham operation group were given the same volume of normal saline.Rats were sacrificed in each group on 14,21,28 d after model construction and the kidney sample was obtained.Immunohistochemistry was used to detect the expression of TGF-β1 and α-SMA.Results Compared with the sham operation group,the TGF-β1 and α-SMA expression levels of renal tissue in the model group were significantly increased(P＜0.05),compared with the model group,the TGF-β1 and α-SMA expression levels on 14,21,28 d of model construction in the baicalin group,baicalin+ benazepril group and benazepril group were decreased to different extents (P＜0.05).But the TGF-β1 and α-SMA levels at each time point had no statistical difference among the baicalin group,benazepril group and baicalin+benazepril group(P＞0.05).Conclusion Baicalin may delay the progress of renal interstitial fibrosis in UUO rat by down-regulating the TGF-β1 expression and reducing α-SMA expression.关键词
