摘要 目的:观察刺五加(AS)注射液对急性脑血栓的治疗效果并探讨其作用机理。方法:1、对急性脑血栓患者采用单盲对照法,刺五加组74例,在常规治疗基础上用AS注射液60ml加入0.9%生理盐水500ml中静脉滴注,每天1次,共14天;对照组74例,以复方丹参注射液20ml静脉滴注,每天1次,共14天。观察临床效果。2、实验研究用大鼠海马脑薄片电生理和组织学检查,观察使用AS注射液(AS组)和未使用AS(对照组)对谷氨酸(Glu)所致的缺血性海马脑片顺向群峰电位(OPS)的影响以及脑片的超微结构变化。结果:(1)临床观察AS组优于对照组。(2)AS组脑片在加入Glu后5分钟OPS减小并消失,去除Glu1小时后OPS恢复率为83.3%,平均恢复程度为86.4%;对照组脑片加入Glu后OPS在3分钟迅速减小并消失,去除Glu1小时后OPS恢复率为16.6%,恢复程度为41.5%。两组比较差异有统计学意义(P<0.05)。(3)电镜下观察发现,加有Glu海马脑片的CA1区锥体细胞核染色加深,核膜不完整,核内染色质凝聚成块,胞浆中内质网高度扩张。使用AS后的神经细胞核膜完整,核内染色质轻度凝聚,内质网轻度扩张。结论:AS注射液可能通过抗Glu毒性作用对急性脑血栓形成有治疗作用。
