摘要:目的探讨滇南血栓颗粒对体外血小板聚集和大鼠下腔静脉血栓形成的影响。方法采用比浊法,以二磷酸腺苷(ADP)为诱导剂,测定滇南血栓颗粒的体血抗血小板聚集活性;采用结扎大鼠下腔静脉的方法,观察滇南血栓颗粒的体内抗血栓作用。结果滇南血栓颗粒可显著对抗ADP诱导的家兔体外血小板聚集,作用呈现浓度依赖性,其半数抑制率(50% inhibitory concentration,IC50)为29.84 mg.mL-1;滇南血栓颗粒可明显减轻大鼠下腔静脉血栓的重量。 结论滇南血栓颗粒在体外、体内均有明显的抗血小板聚集、抗血栓形成作用。

【Abstract】Objective: To study the effect of Diannan Thrombus Particles on platelet aggregation in vitro and rat inferior vena cava thrombosis. Methods: The turbidimetry was used to measure the activity of body blood thrombus particles by using adenosine diphosphate (ADP) as inducing agent, and the rat vena cava ligation method used to observe the anti-thrombotic effect of Diannan Thrombus Particles. Result: Diannan Thrombus Particles could significantly confront the ADP-induced platelet aggregation in rabbits, in a concentration-dependence and its half inhibition rate (50% inhibitory concentration, IC50) was 29.84 mg·mL-1. And it could significantly reduce the weight of the inferior vena cava thrombosis in rats. Conclusion: Diannan Thrombus Particles has a significant anti-platelet aggregation and antithrombotic effect in vitro and in vivo.

随着人口老龄化进程的加速,血栓栓塞性疾病的发病率呈逐年上升的趋势。据世界卫生组织统计,全球每年约有1500万人死于血栓栓塞性疾病,我国每年该病发病人数有1000万,病死人数有100万,因此,提高血栓栓塞性疾病的防治水平,降低其发病率、致死率、致残率,减少由此而产生的一系列社会问题已成为当务之急。滇南血栓颗粒是云南省血液病学研究中心血液病中西医结合研究室的经验方,采用本省出产的滇三七、木姜子及地龙等药组成,其临床应用于难治性深静脉血栓不仅对急性期血栓溶栓效果好,而且对西医尿激酶、链尿激酶联合肝素、抗血小板药无效的顽固性、完全梗阻性深静脉血栓均有较好的疗效。但滇南血栓颗粒抗血栓的作用机制尚不清楚,本文从体外抗血小板聚集和体内抗血栓形成两方面对滇南血栓颗粒的抗血栓作用进行了研究。……
