1、温阳活血方上调慢性马兜铃酸肾病大鼠肾组织血管生成素1mRNA表达作者：王红婷,王云满,梁永平,刘育军,彭文【摘要】　　目的：观察温阳活血方对慢性马兜铃酸肾病大鼠肾组织血管生成素（angiopoietin,Ang）表达的影响，并探讨其保护作用机制。　　方法：将28只雄性SD大鼠随机分为正常对照组、模型组和温阳活血方组。模型组大鼠予关木通水煎液10ml/(kg·d)灌胃，温阳活血方组于模型组基础上，再予温阳活血方30g/(kg·d)灌胃。20周后，采用实时逆转录聚合酶链式反应方法检测3组大鼠肾组织中Angl和Ang2mRNA的表达。　　结果：与正常对照组比较，模型组大鼠肾组织Ang1m

2、RNA表达明显减少（P<0.01），Ang2mRNA表达明显升高（P<0.01）；与模型组大鼠比较，温阳活血方组大鼠肾组织Ang1mRNA表达升高（P<0.01），Ang2mRNA表达下降，但差异无统计学意义（P>0.05）；肾脏病理显示温阳活血方组肾损害较模型组明显减轻。　　结论：温阳活血方通过上调Ang1mRNA的表达发挥对慢性马兜铃酸肾病大鼠肾脏保护作用。【关键词】马兜铃酸;温阳活血方;血管生成素类;关木通;大鼠;肾病　　Objective:ToinvestigatetheeffectsofWenyangHuoxueRecipe(WRHXR),aco
