摘要: 目的: 研究川芎嗪抗血栓作用及机制。方法: 观察大鼠灌胃给予川芎嗪(20、 40和 80 mg/kg)后对下腔静脉结扎和电刺激致血栓形成的影响,同时测定家兔灌胃给予的川芎嗪(10、20和 40 mg/kg)后对凝血酶、二磷酸腺苷(ADP)、胶原诱导的血小板聚集率、非闭塞性静脉血栓形成、凝血酶抑制率和对血浆凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)的影响。结果: 川芎嗪对凝血酶、ADP诱导的血小板聚集均有抑制作用,但对胶原诱导的抑制能力较弱。川芎嗪有效地减少实验动物动静脉血栓的形成,在体内与凝血酶也有一定的亲和力,且能较好地延长PT。结论: 川芎嗪具有一定的抗血栓作用,其机制可能与保护内皮与抑制血小板聚集有关。

Abstract: AIM: To investigate the effect and mechanism of tetramethylpyrazine on antithrombotic. METHODS: The effect of tetramethylpyrazine (20, 40, 80 mg/kg, i.g.) on thrombosis induced by inferior vena cava ligation and electrically mediated carotid arterial in rats were evaluated.And studies were also conducted in rate of platelet aggregation, non-occlusion thrombosis, thrombin inhibition and plasm pro-time prothrombin time(PT) and activated partial thromboplastin time (APTT) in rabbits of different does of tetramethylpyrazine (10, 20, 40 mg/kg, i.g.). RESULTS: Tetramethylpyrazine showed competent anti-thrombin activity and inhibited platelet aggregation induced by thrombin and ADP, but presented lower potency in platelet aggregation induced by collagen. In addition it markedly decreased venous and arterial thrombosis and extended PT. CONCLUSION: Tetramethylpyrazine has a significant effect on antithrombosis in vivo. The mechanism seems to be related to the inhibition of platelet aggregation and protection of endothelium.
