摘　　要：目的:观察益气活血方及其拆方对健康人血小板聚集功能的影响来探讨其配伍规律。方法:健康献血者静脉采血抗凝,制备富血小板血浆(platelet rich plasma,PRP)和贫血小板血浆(platelet poor plasma,PPP),然后在比浊管中加药孵育,用血小板聚集仪检测二磷酸腺苷(adenosine diphosphate,ADP)、血小板活化因子(platelet ac-tivating factor,PAF)、花生四烯酸(arachidonic acid,AA)诱导的最大聚集率。结果:益气活血方能显著提高ADP,PAF诱导的血小板聚集功能,其中黄芪、当归配伍为方中主药,益气药与活血药相须为用才能发挥促聚作用。结论:益气活血方体外实验能增强健康人血小板聚集功能,但确切作用机制有待进一步实验验证。Objective： To investigate and explain the composing mechanism by observing enhancement property of disassembled compositions of Yiqi Huoxue decoction （YQHXD） on platelet aggregation of health adults. Method： Venous whole blood was obtained from healthy human subjects and anti-coagulated, and then centrifuged to produce platelet-rich plasma （PRP） and platelet-poor plasma （PPP）. Disassembled compositions of YQHXD and sodium chloride were placed in different translucent tubes containing PRP and PPP, calculated the maximum percents of platelet aggregation stimulated by platelet agonists： adenosine diphosphate （ADP）, platelet activating factor （PAF） and arachidonic acid （AA）. Result： The maximum percents of platelet aggregation induced by ADP and PAF were largely improved by YQHXD, both astragalus membranaceus and Angelica Scinesis played the most important roles in the decoction, the herbs of Yiqi and Huoxue must work together to enhance platelet aggregation. Conclusion： In vitro study, YQHXD can markedly improve platelet aggregation of health adults, but the exact mechanism should be proved by further experiments.
