摘要
目的:探讨跑台运动对脑缺血再灌注大鼠海马脑源性神经营养因子(BDNF)、血管内皮生长因子(VEGF)和VEGF受体KDR mRNA表达的影响。方法:使用可逆性阻塞大脑中动脉的方法建立大鼠单侧脑缺血再灌注模型,将符合模型条件的16只大鼠随机分为对照组和运动组,运动方式采取小强度跑台运动,为期1周。另选取8只大鼠作为假手术组。实验后采用实时荧光定量PCR方法测定大鼠海马组织中BDNF、VEGF及KDR mRNA表达。结果:(1)对照组和运动组大鼠缺血侧海马BDNF mRNA表达量显著高于非缺血侧。运动组大鼠缺血侧海马BDNF mRNA表达量显著高于对照组。(2)对照组大鼠海马缺血侧VEGF mRNA表达量显著高于非缺血侧。运动组大鼠两侧海马VEGF mRNA水平分别显著高于对照组。(3)对照组和运动组大鼠缺血侧海马KDR mRNA表达量显著高于非缺血侧。运动组大鼠缺血侧海马KDR mRNA水平显著高于对照组。结论:跑台运动可明显提高缺血再灌注大鼠海马部位BDNF、VEGF及KDR mRNA水平。
