1、 血脂康胶囊对糖尿病大鼠肾脏TGF-1表达影响及保护性研究摘 要目的: 观察糖尿病大鼠肾脏TGF-1表达及血脂康胶囊的治疗作用 方法: 采用 STZ 注射法制作 DM 大鼠模型,随机分为正常对照组,糖尿病对照组,血脂康胶囊治疗组。灌胃给药 8 周后,分别测定24小时尿白蛋白排泄、肾小球滤过率、肾皮质 TGF-1、Col-IV、FN 的表达。所采用的技术包括生化、免疫组化等。结果一、功能学变化:1. 血脂康胶囊治疗组大鼠的 24 小时 UAER 显著低于DM 对照组: 2. 血脂康胶囊治疗组大鼠的肾小球滤过率显著低于 DM 对照组 二、免疫组化:血脂康胶囊治疗组大鼠肾皮质 TGF-1、 FN、C
2、ol-IV 的表达显著低于糖尿病对照组(P 0.05)。关键词:血脂康胶囊;糖尿病肾病;大鼠;氧化应激;抗炎The protective effects of xiezhikang on the kidney of diabetic rats and the study of mechanismABSTRACTObjective To investigate the effects of xiezhikang on the kidney of diabetic rats, as well as possible the mechanism involved in.MethodsAfterbei
3、ng injected with streptozotocin(STZ) the DM rat model was established. Rats were randomly divided into 4 groups. Group 1 was normal group.Group 2 was diabetic control group. Group 3 was given the C. After 8 weeks of administration, UAER, GFR of rats were determined respectively. TGF-1, FN, Col-IV, i

Techniques.Including biochemistry, immuhisto chemistry, Results 1. 24h UAER of xiezhikang group were significantly lower than those of diabetic control group2. GFR of xiezhikang group were significantly lower than those of diabetic control group 4. The expres

The protective mechanism may be associated
6、with the its improvement of oxidative stress and anti-inflammatory activity. In addition, it might relate to inhibitory effect on the proliferation of murine mesangial cells.Key words: clerodendranthus; nephropathy; rat; oxidative stress; anti-inflammatory前 言糖尿病肾病( DN)为糖尿病的主要慢性并发症之一,而且已成为导致终末期肾衰的重要原
7、因。DN 发病机制复杂,其中涉及糖代谢紊乱、肾脏血流动力学改变,多种细胞因子及遗传背景等。目前国内外研究认为,TGF-1等多种细胞因子分泌增多和细胞外基质(ECM)蛋白代谢异常,在 DN 发病机制的各个环节起着重要的作用,本实验拟血脂康胶囊作为干预因素,观察其对糖尿病大鼠尿白蛋白排泄率,肾小球滤过率(GFR),肾脏皮质 TGF-1、Col-IV、FN 表达等指标的影响。探讨血脂康胶囊对早期糖尿病肾病是否有保护作用,为临床医医生诊治早期糖尿病肾病提供依据。材 料 与 方 法1.1 实验动物:清洁级雄性 SD 大鼠 50 只,体重 180-200 克,1.2 实验药物:血脂康胶囊购自廊坊市医药分公
