摘要
目的观察华佗再造丸对大鼠局灶性脑缺血后低氧诱导因子(HIF-1α)和血管内皮生长因子(VEGF)的影响。方法建立大鼠大脑中动脉栓塞(middle cerebra1αrteryocclusion,MCAO)模型。将SD大鼠分为假手术组、模型组、华佗再造丸(0.5,1.0,2.0 g/kg)三个剂量组。采用SYBR green实时荧光定量PCR检测各组大鼠脑内HIF-1α和VEGF mRNA表达。结果与假手术组相比,MCAO造成脑缺血损伤3天后HIF-1α,VEGF基因的mRNA表达水平降低,华佗再造丸各剂量组可明显提高HIF-1α,VEGF mRNA的表达水平,并呈现出一定的剂量关系。结论华佗再造丸能够增强大鼠局灶性脑缺血后HIF-1α和VEGF的表达,通过HIF-1α/VEGF通路促进脑缺血后的血管新生和神经再生,可能是其抗脑缺血的作用机制之一。
