摘要
为探讨组织血管紧张素转化酶在兔血管成形术后内膜增生中的作用及苯那普利对其的影响,建立了充血管再狭窄模型,每天用lmg/kg和10mg/kg的苯那普利饲养后进行HE染色、免疫组织化学分析、生物化学分析和酶活性测定。结果发现手术组组织血管紧张素转化酶活性显著增高(P<0.01),内膜损伤面积与组织血管紧张素转化酶活性呈非常显著相关(r=0.708,P<0.01);大剂量组组织血管紧素张转化酶活性下降59%,内膜捐伤面积减少43%(P<0.01);小剂量组组织血管紧张素转化酶活性轻度下降(P<0.05),内膜损伤面积无显著变化。提示血管组织血管紧张大转化酶过度表达可能在再狭窄形成过程中起重要作用,大剂量苯那普利可以通过抑制血管组织血管紧张素转化酶以减少内膜增生。
