摘要
研究脑缺血/再灌流损伤中IL-1、TNF的来源、变化规律和作用。方法用免疫组化方法检测了局部脑缺血/再灌流大鼠模型中IL-1β、TNF-α的表达。结果缺血组(I)3hlL-1β表达增多并持续至120h,缺血再灌流组(IR)0.5hIL-1β即明显增高,高峰在24h,120h已降至对照组(C)水平,阳性细胞主要为纹状体区及顶叶皮层的神经元、胶质细胞和血管内皮细胞;I组和IR组0.5hTNF-α表达增多,12h达高峰,持续至120h,阳性细胞为纹状体和缺血皮层的神经元和胶质细胞。结论IL-1β、TNF-α参与缺血/再灌流脑损伤,其来源于损伤局部的神经元、胶质细胞及血管内皮细胞,并对其作用进行了探讨。
