摘要

目的:探讨NF-κB在大鼠脑缺血再灌注后炎性反应中的作用。方法:制备脑缺血再灌注模型。24h后

免疫组化检测假手术组、模型组和干预组中NF-κB p65的表达

测定脑组织匀浆中性粒细胞趋化因子（CINC）含量变化

同时观察海马CA1区病理组织学改变。结果:模型组大鼠脑组织的NF-κB p65阳性表达和CINC含量与假手术组相比明显增高

P<0.05;干预组大鼠脑组织的NF-κB p65阳性表达和CINC含量与模型组相比明显受抑制

P<0.05。干预组脑组织病理改变较模型组轻。结论:NF-κB参与了脑缺血再灌注后炎性反应中前炎性因子的调控过程。

Abstract

Objective:To investigate the role of nuclear factor-κB(NF-κB)in rats with cerebral ischemia-reperfusion injury. Methods:Rat models of cerebral ischemia-reperfusion were established.24hours later

the expression of NF-κB in rat brain of sham-operation group

operation group and intervention group was detected with immunohistochemistry method

Cytokin-induced neutrophil chemotactics(CINC)in rat brain were measured and histopathological examinations were conducted on the hippocampal CAl.Results:The expression of NF-κB p65 and CINC in the operation group increased significantly compared with the sham-operation group(P<0.05).But the expression of NF-κB p65 and CINC in the intervention group were inhibited significantly compared with the operation group(P<0.05).The pathological changes of the intervention group were slighter than those of the operation group.Conclusion:The results suggest that NF-κB may play an important role in the release of inflammation factors and gathering of inflammation cells induced by ischemia-reperfusion injury.
