摘要 目的 :探讨大鼠脑创伤后促炎症细胞因子TNF α、IL 6、IL 8和抗炎症细胞因子IL 10的动态变化及其作用。方法 :①采用气体冲击致大鼠局部脑创伤模型 ;②HE染色观察组织病理学变化 ;③采用放射免疫检测 (radioimmunoassay ,RIA)技术测定假手术组和创伤组大鼠脑组织内TNF α、IL 6、IL 8和IL 10在各时段的含量。结果 :①脑创伤组与假手术组比较 ,TNF α、IL 8和IL 10从 3h ,IL 6从2 4h开始 ,含量显著性升高 ,并均持续较长时间 (本实验为 168h) ;②促炎症细胞因子TNF α、IL 6与抗炎症细胞因子IL 10呈相关性。结论 :促炎症和抗炎症细胞因子均参与了继发性脑损伤 ,其具体作用有待继续深入研究。
