| 摘 要： | 目的：观察连黄降浊颗粒对5/6肾切除大鼠肾功能和肾皮质细胞外基质（ECM）积聚的影响。方法：将45只Wistar大鼠随机取8只为正常对照组,余用5/6肾切除法建立慢性肾衰竭（CRF）动物模型,将造模成功后的大鼠随机分为模型组、尿毒清颗粒组（对照组）、连黄降浊颗粒低剂量组（低剂量组）、连黄降浊颗粒高剂量组（高剂量组）,分别给予相应浓度和剂量的药物。实验期间测定大鼠的肾功能、尿蛋白,治疗12周后观察其肾脏病理改变,免疫组化法检测肾小球Ⅳ型胶原（ColⅣ）、纤连蛋白（FN）和肾皮质基质金属蛋白（MMP-2）和金属蛋白酶组织抑制物（TI MP-2）蛋白表达。结果：连黄降浊颗粒能明显改善CRF大鼠肾功能、减少尿蛋白的排出（P〈0.05～0.01）,减轻肾脏病理损害;连黄降浊颗粒能下调TI MP-2蛋白表达,增加MMP-2活性,抑制了FN、ColⅣ在肾组织的表达（P〈0.01）,减轻ECM积聚。结论：连黄降浊颗粒可明显改善肾功能,增加肾脏MMP-2活性,降低TI MP-2表达,增加ECM降解,减轻肾小球硬化。

| Abstract: | Objective:To study the effect of Lianhuang Turbid Clearance Granules(LHTCG) on the renal function and the accumulation of extracellular matrix(ECM) in renal cortex of nephrectomized rats(NXR).Methods:Eight Wistar rats were served as normal group,and the 5/6 NX rats were randomly divided into 4 groups:the model group,the niaoduqing granules group,the low-dosage of LHTCG group and the high-dosage of LHTCG group.Medicine was given to each group according to the designed concentration and dosage.The therapeutic... |
