摘要
目的探讨复方丹参滴丸对早期糖尿病肾病的保护作用及可能机制。方法腹腔注射链脲佐菌素建立高血糖大鼠动物模型。造模成功的大鼠随机分为模型组、复方丹参组以及厄贝沙坦组,分别给予蒸馏水、复方丹参滴丸及厄贝沙坦灌胃。另设正常对照组以同体积蒸馏水灌胃。测定尿白蛋白、血肌酐及血糖;肾脏组织行PAS、Masson染色,电镜观察超微结构,免疫组化检测肾组织血管内皮生长因子(VEGF)、结缔组织生长因子(CTGF)、巨噬细胞趋化蛋白-1(MCP-1)的表达。结果复方丹参滴丸大剂量时可减少尿白蛋白排泄率、减轻肾脏的病理变化。降低肾小球VEGF、CTGF、MCP-1蛋白表达水平。结论复方丹参滴丸能有效改善糖尿病所致的肾脏损害,其保护作用可能与降低生长因子和炎症因子有关。
Objective To explore the effects of Compound Danshen Dripping Pills (CDDP) on kidney disease in streptozocin-induced rats of hyperglycemia, and its underlying mechanism early diabetic Methods Hyperglycemic rat animal model was established by intraperitoneal injection of streptozotocin. The model rats were then randomly divided into model group, Compound Danshen Dripping group and irbesartan group. They were then given distilled water, compound Danshen Dripping Pills and irbesartan by intragastric administration, respectively. An additional control group received the same volume of distilled water instead. Urinary albumin, serum creatinine and blood glucose were determined; kidney tissues were observed by PAS and Masson staining; the renal ultrastructures were assessed by electron microscopy. The VEGF, CTGF, and MCP-1 expressions were immunohistochemically detected. Results Compound Danshen Dripping Pills in large doses reduced blood sugar and urinary albumin excretion rate. The renal pathological changes were ameliorated by Compound Danshen Dripping pills. VEGF, CTGF, MCP-1 protein expression levels were decreased. Oonclusion Compound Danshen Dripping Pills can effectively reduce renal damage caused by diabetes, which may be related to the decreased expressions of VEGF and inflammatory factors.
