摘要:

目的    研究脑心通对局灶性脑缺血再灌注损伤后大鼠的保护作用。方法    随机将健康雄性SD大鼠30只分为假手术组(A组)、缺血组(B组)、脑心通治疗组(C组),每组10只,B组和C组采用大脑中动脉线栓法制备大鼠局灶性脑缺血再灌注模型,采用免疫组织化学法和Western blot法检测脑组织中小胶质细胞的激活及人白细胞分化抗原68(CD68)、白细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)的表达。结果     脑缺血灶范围内CD68、TNF-α、IL-1β的表达,B组明显高于A组,C组明显低于B组。结论    脑心通通过抑制脑缺血再灌注损伤后炎症反应,对脑缺血大鼠有一定程度的神经保护作用。

Abstract:

Objective     To investigate the protective effect of Naoxintong on reperfusion after focal cerebral ischemia in rats and explore effective methods to interfere with inflammation following acute cerebral ischemia-reperfusion injury. Methods     Thirty male SD rats were randomly divided into three groups: the sham operation group(group A, n=10), the ischemic group (group B, n=10), and the Naoxintong group(group C, n=10). Group B and C had focal cerebral ischemia-reperfusion produced by right middle cerebral artery occlusion. Activation of microglia, and expressions of CD68,IL-1β and TNF-α were detected by immunohistochemistry and Westernblot. Results    Expressions of CD68, IL-1β and TNF-α were more markedly increased in group B than those in group A, and significantly lower in group C than those in group B. Conclusion    Naoxintong can inhibit inflammation reaction after cerebral ischemia, which can provide an inhibitory effect on cerebral ischemiareperfusion injury in rats.
