摘要
目的:观察大鼠主动脉球囊内皮剥脱对血小板活化的影响。方法:在大鼠主动脉球囊内皮剥脱模型上,分别于术后7,14和21天观察球囊内皮剥脱对血小板活化的影响。结果;大鼠球囊内皮剥脱术后,于7,14,21天时,血小板聚集明显增强,蛋白激酶)PKC)活性明显增高,环酸腺苷活性明显降低,均以7天组最为明显。结论:临床PTCA后较长时间应用抗栓剂是必要的。
Objective To observe the effect of ballon angioplasty on platelet activation .Method: By using the model of endothelial denudation with balloon, the blood samples were takm on 7,14 and 21 days and examined. Results:The platelet aggregation and proteinkinase C(RKC)activity were obviously enhanced,while cyclic monophosphate (cAMP) activity was decreased after baslloon angioplasty, Conclusion:after percutaneous transluminal coronary angplasty ,it is necessary to use anti-thrombotic agents long period.
