摘要
目的 探讨通心络胶囊保护神经元缺血性损伤的作用机制。方法  2 8只Wistar大鼠随机分为 5组 :空白对照组 (4只 )、伪手术组 (4只 )、通心络胶囊小剂量组 (8只 )、通心络胶囊大剂量组 (8只 )、华佗再造丸组 (4只 )。分离培养鼠脑毛细血管内皮细胞 (CCEC)和多形核白细胞 (PMN) ,利用微管吸吮技术 ,观察PMN与CCEC间粘附力学特性的变化。结果 脑缺血—再灌注后各时间点的PMN与CCEC粘附力和粘附应力均明显高于正常对照组和伪手术组 (P均 <0 .0 1) ;加通心络胶囊后 ,细胞粘附力和粘附应力均明显下降 (P <0 .0 5或P <0 .0 1)。结论 脑缺血—再灌注损伤后通心络胶囊使PMN与CCEC粘附力减小 ,粘附应力下降 ;抗粘附分子抗体将可能成为治疗缺血性脑血管疾病的一条新的有效途径
