目的:观察六味地黄汤对单侧输尿管梗阻(UUO)大鼠模型中单核趋化蛋白-1(MCP-1)及转化生长因子-β1(TGF-β1)表达的影响。方法:将72只雄性SD大鼠随机分为模型组、依那普利组、六味地黄汤组、假手术组,行UUO术后即预药物干预。于术后第7、14、21天分别处死各组大鼠。用HE和Masson染色法观察各组大鼠术后不同时间点肾脏病理改变,用免疫组化法检测肾小管间质MCP-1及TGF-β1表达。结果:与假手术组比较,其余3组各时间点MCP-1及TGF-β1表达均明显高于假手术组(P〈0.05);六味地黄汤组的MCP-1和TGF-β1表达明显低于模型组各时间点(P〈0.05),高于依那普利组(P〈0.05)。结论:六味地黄汤可下调MCP-1和TGF-β1的表达,减缓UUO大鼠肾小管间质损害,可作为梗阻性肾病辅助用药。
Objective:To observe the effect of Liuweidihuang decoction(LD)on expression of monocyte chemotactie protein (MCP- 1 ) and transforming growth factor(TGF - β1) in unilateral ureter obstraction(UUO) rats. Methods: Seventy - two male Sprague - Dawley rats were randomly divided into four groups: the model group, the sham - operation group, the Enalapril group and LD group. The kidneys of rats were harversted at 7, 14 and 21 d after the operation. Immunohistochemistry was used on the renal tissue for MCP- 1 and TGF - β1 after7,14 and 21 day. Histological changes were also observed by HE and Masson staining. Results: Compared with those in the sham - operation group, the levels of MCP - 1 and TGF -β1 expression was obviously higher than those in the other groups on day 7,14,and 21(P〈0.05).The MCP- 1 and TGF-β1 of in LD group was higher than that in Enalapril group on day 7,14, and 21 ( P 〈 0.05). Conclusion: LD can decrease the expression of the UUO MCP - 1 and level and TGF -β1 and reduce tubuloninterstitial injury, and LD can be an axillary drug for obstruct kidney disease.
