摘要 目的探讨急性心肌缺血后老年大鼠VEGFR-1、VEGFR-2的表达特点。方法复制大鼠心肌梗死模型,采用RT-PCR技术同管扩增VEGFR-1、VEGFR-2和内参基因GAPDH,以VEGFR-1/GAPDH、VEGFR-2/GAPDH比值为研究对象,分析冠状动脉结扎后第1、3、6h,1、3、7d年轻和老年大鼠心肌梗死边缘区VEGF受体的表达。结果急性缺血后年轻和老年组大鼠心脏VEGFR-1mRNA表达均增加,缺血后1、3、24h,3、7d老年大鼠VEGFR-1与GAPDHmRNA比值比年轻大鼠低,两者的差别具有统计学意义。年轻组VEGFR-2很快上升达到峰值,随后很快下降。而老年组缺血后VEGFR-2无显著改变。结论缺血后老年大鼠心脏VEGFR-1和VEGFR-2的表达和年轻大鼠不同,是否与老年大鼠心脏血管生成能力减低有关还有待于进一步研究。
