摘要 目的:探讨环氧化酶-2(COX-2)、血管内皮生长因子(VEGF)在晚期缺血预适应(DPC)心肌及远隔器官(RPC)肝脏中的表达。方法:新西兰兔20只,随机分为DPC组及正常对照组,每组各10例。结扎兔冠状动脉左前降支建立缺血预适应模型,24h后取心肌及肝脏组织,免疫组化法测定心肌及肝脏COX-2、VEGF表达。结果:兔DPC心肌及肝脏COX-2、VEGF表达量比对照组明显增强,差异有显著性(P<0.05)。心肌非缺血区与对照组表达有显著差异性(P<0.05)。结论:缺血缺氧可刺激心肌COX-2、VEGF表达明显增强,心肌非缺血区及远隔器官肝脏也大量表达,COX-2、VEGF可能是参与抗缺血、冠状动脉侧枝血管形成及远隔器官保护效应中的重要物质。
