【摘 要】 目的:通过观察金蛭方对缺血性中风大鼠白介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)表达的影响,探讨其治疗缺血性中风的作用机制。方法:采用线栓法复制缺血性中风大鼠模型,随机分为假手术组、模型对照组、金蛭方高剂量组、金蛭方低剂量组、阳性药尼莫地平片对照组。测定大鼠血清和脑组织IL-1β、TNF-α的含量。结果:与假手术组比较,缺血性中风大鼠血清及脑组织IL-1β、TNF-α的含量均显著降低(P<0.01)。与模型组比较,各治疗组均能降低IL-1β、TNF-α的含量(P<0.01)。结论:金蛭方通过调节缺血性中风大鼠IL-1β、TNF-α的分泌和释放以达到拮抗缺血性中风作用。

Abstract:Objective To explore the effects of the Jinzhif,Prescription on ischemic stroke rat interleukin - 1 beta (IL-1), the effect of the expression of tumor necrosis factor alpha (TNF alpha), and to explore its mechanism in the treatment of ischemic stroke. Methods Using the suture method to copy the rat model of ischemic stroke were randomly divided into sham operation group, model control group, the Jinzhi Prescription high dose group, the Jinzhi Prescription low dose group, positive drug nimodipine tablets in the control group. The contents of IL-1 and TNF-α in serum and brain tissue of rats were determined. Results Compared with sham operation group, the contents of IL-1 and TNF-α in serum and brain tissue of rats with ischemic stroke were significantly decreased (P<0.01). Compared with the model group, the treatment group could decrease the content of IL-1 and TNFα- (P<0.01). Conclusion The Jinzhi Prescription through regulation of ischemic stroke rat IL-1, TNF -α secretion and release in order to achieve the antagonistic effect of ischemic apoplexy.

金蛭方系課题组经过多年筛选出的治疗缺血性中风的效方,临床应用10余年,但其治疗作用机制尚不十分明确。脑缺血后发生脑损害的机制复杂,炎性反应是缺血性脑损害的主要机制之一[1]。在参与炎症反应的众多因子中,最有影响的是IL-lβ和TNF-α[2]。但中药对缺血性中风大鼠IL-1β、TNF-α水平变化影响的报道相对较少。研究旨在通过观察金蛭方对缺血性中风大鼠血清及脑组织IL-1β、TNF-α表达的影响,探讨其治疗缺血性中风的部分作用机理。
