| 摘 要： | 目的观察活血化瘀消癥通络中药对糖尿病肾病(DN)大鼠作用及其机制。方法将46只健康雄性SD大鼠随机分为正常组(10只),另36只一次性腹腔注射链脲佐菌素制备DN大鼠模型,随机分为模型组、贝那普利组、中药组,每组各12只。模型制备成功1周后贝那普利组、中药组每日同体积灌胃给予相应药物,正常组及模型组灌喂等量蒸馏水,各组连续给药23周后处死动物。HE、PAS染色观察肾组织病变程度,放射免疫法测定大鼠肾组织中血管紧张素(Ang)的含量、采用紫外分光光度法测定血管紧张素转换酶(ACE)活性,免疫组织化学法和RT-PCR法检测大鼠肾组织中ACE、血管紧张素转换酶相关羧肽酶(ACE2)蛋白和基因的表达。结果与模型组相比,中药组大鼠肾小球毛细血管基底膜增厚及肾小球系膜细胞增生、系膜基质增多、系膜区增宽等现象明显减轻;中药组大鼠肾组织中Ang的含量和ACE活性较模型组降低(P0.01),肾组织中ACE2蛋白及基因的表达显著增高(P0.05或P0.01)。结论活血化瘀消癥通络中药能够减轻DN的病理损害,这一作用的实现可能是部分通过调节血管紧张素系统实现的。

| Abstract: | Objective To observe the effect of blood-activating and stasis-dissolving herbs on rats with diabetic nephropathy (DN) and its mechanism.Methods Forty-six healthy male Sprague-Dauley rats were randomized into normal group (10 rats) and DN model group (36 rats) was established by streptozotocin injection into abdominal cavity, which was subrandominzed into model group, benazepril group, and herbal group, 12 rats in each. One week after modelling, the treatment groups were medicated by gavage in the same volu... |
