摘要 目的研究达肝素钠对兔血小板活化的影响以及阿司匹林和氯吡格雷的干预。方法纯种新西兰家兔12只,给予阿司匹林或氯吡格雷或二者合用喂饲,静脉注射达肝素钠前及注射后20、30min检测ADP、AA诱导的血小板聚集、血浆CD62P和vWF的水平。结果应用达肝素钠后血小板聚集、CD62及vWF无明显增加;与基线水平比较,阿司匹林组加用氯吡格雷两药合用,静脉注射达肝素钠前(9.50±4.18vs2.67±1.63)及注射后20min(10.50±3.21vs2.83±1.66)ADP诱导的血小板聚集均明显降低。单用阿司匹林喂饲7d,应用达肝素钠后血小板聚集增加(7.00±4.10vs12.50±4.04)。结论达肝素钠不会引起血小板激活;阿司匹林与达肝素钠合用增加血小板聚集;氯吡格雷与阿司匹林两药合用明显降低血小板聚集。
