Abstract： 目的观察穿心莲有效成分--API(API)对溶栓后再闭塞的预防作用,并探讨其可能机制.方法用血管外电刺激方法复制冠脉血栓模型,溶栓后14只犬被随机分为API治疗组(n＝6)和对照组(n＝8),治疗4周.溶栓4h、3d、30d测定血浆凝血恶烷B2(TXB2)6-酮前列腺素F,组织型纤溶酶原激活剂,纤溶酶原激活剂抑制剂水平,并进行组织病理学检查.结果治疗组再闭塞率为16.7%,对照组为87.5%,P＜0.01.血浆TXB2显著低于对照组(P＜0.01,P＜0.01,P＜0.05),30d对照组血浆血小板颗粒膜蛋白(GMP-140)为基础水平的3倍,而治疗组接近基础值(与对照组比较P＜0.001).结论穿心莲有效成分API有预防溶栓后再闭塞作用,机制与其抗血小板活化,抑制TXA2产生等有关.
