目的 探讨舒脑欣滴丸对急性血瘀模型大鼠血小板聚集和血液流变学指标的影响。方法 选取70只Wistar大鼠，随机分为对照组，模型组，舒脑欣滴丸13、26、52 mg/kg组，阳性药脑心通胶囊（15 mg/kg）、阿司匹林肠溶片（15 mg/kg）和藻酸双脂钠片（90 mg/kg）组，连续ig给药7 d，1次/d，末次给药后1 h，采用sc 0.1%肾上腺素加在冰水中游泳的方法，制备大鼠急性血瘀模型，观察舒脑欣滴丸对不同血小板聚集诱导剂二磷酸腺苷（ADP）、花生四烯酸（AA）和胶原（CG）引起的大鼠血小板聚集影响；通过检测血液流变学指标、凝血功能评价舒脑欣滴丸对血瘀模型大鼠的作用。结果 舒脑欣滴丸对3种不同血小板聚集诱导剂引起的血小板聚集均有不同程度的抑制作用，可显著降低全血黏度，延长血瘀模型大鼠凝血酶原时间（PT）、活化部分凝血活酶时间（APTT）。结论 舒脑欣滴丸13、26、52 mg/kg具有明显活血化瘀作用，能降低血液黏度，抑制多种诱导剂引起的血小板聚集，具有一定抗凝活性。

Objective To investigate the effect of Shunaoxin Dropping Pills on platelet aggregation and hemorheology in rats with acute blood stasis. Methods Wistar rats (70 cases) were randomly divided into control group, model group, Shunaoxin Dropping Pills (13, 26 and 52 mg/kg) groups, positive drugs Naoxintong Capsules (15 mg/kg), Aspirin Enteric-coated Tablets (15 mg/kg), and Alginic Sodium Diester Tablets (90 mg/kg) groups. Rats were administrated continuously for 7 d, once daily. One hour after the last administration, the rats were injected sc with 0.1% adrenaline and swimming in ice water to prepare acute blood stasis model. The effects of Shunaoxin Dropping Pills on platelet aggregation induced by adenosine diphosphate (ADP), arachidonic acid (AA), and collagen (CG) were observed. The effects of Shunaoxin Dropping Pills on blood stasis model rats were evaluated by detecting hemorheology indexes and coagulation function. Results Shunaoxin Dropping Pills had different inhibitory effects on platelet aggregation induced by three kinds of platelet aggregation inducers. Shunaoxin Dropping Pills could reduce blood viscosity, and prolong prothrombin time (PT) and activated partial thromboplastin time (APTT) of rats with blood stasis. Conclusion Shunaoxin Dropping Pills (13, 26, and 52 mg/kg) can obviously promote blood circulation, remove blood stasis, reduce blood viscosity, and inhibit platelet aggregation caused by various inducers, and have certain anticoagulant activity.
