【摘要】 目的:研究川芎苯酞对大鼠局部脑缺血的保护作用并探讨其作用机理。方法:栓线法制作大鼠大脑中动脉缺血模型(MCAO),观察川芎苯酞对大鼠脑缺血的影响;采用在体动脉血栓形成、静脉血栓形成法,观察其对血栓形成的影响;并研究了其对大鼠血小板聚集、血液流变性的影响。结果:川芎苯酞(25,50mg·kg-1)灌胃给药明显改善大脑中动脉栓塞所致脑缺血大鼠的行为障碍,减少脑缺血区梗死面积,抑制大鼠体内血栓的形成和ADP诱导的大鼠血小板聚集,改善大鼠血液流变性。结论:川芎苯酞对大鼠局部脑缺血具有明显的抑制作用,机制可能与其改善凝血状态、抑制血小板依赖性血栓的形成有关。更多还原

【Abstract】 Objective: To study the protective effect of ligusticum chuanxiong phthalides on cerebral ischemia in rats and its related mechanism of action. Method: Middle cerebral artery occlusion (MCAO) model, thrombosis formation, platelet aggregation and hemorrheological parameters were measured to evaluate the protective effect of ligusticum chuanxiong phthalides. Result: Ligusticum chuanxiong phthalides could markedly decrease the infarct size and behavior deficits score, inhibit the thrombus formation and platelet aggregation, ameliorate hemorrheological parameters with a dose-dependent manner in rats. Conclusion: Ligusticum chuanxiong phthalides has protective effects on focal cerebral ischemia in rats, and its mechanism may be relevant to its inhibition of platelet-dependent thrombosis and amelioration of hemarheologoical parameters.更多还原
