摘要 目的研究喹硫平对小鼠脑缺血后胶质增生及白介素(IL)-1β表达的影响及其作用机制。方法小鼠分为假手术组、药物对照组、缺血组、药物保护组;采用激光共聚焦显微镜方法观察脑缺血后胶质增生及IL-1β表达情况;采用Western印迹方法检测脑缺血后核因子(NF)-κBp50及p65蛋白的表达。结果缺血组与假手术组比较GFAP-IL-1β共表达阳性细胞(黄色)数量明显增加(P<0.01);药物保护组与缺血组比较GFAP-IL-1β共表达细胞(黄色)数量明显减少(P<0.01)。缺血组与假手术组比较NF-κBp50蛋白表达量增加(P<0.05);药物保护组与缺血组比较NF-κBp50蛋白表达量减少(P<0.05)。缺血组与假手术组比较NF-κBp65蛋白表达量增加(P<0.05);药物保护组与缺血组比较NF-κBp65蛋白表达量减少(P<0.05)。结论喹硫平能够减轻小鼠脑缺血后胶质增生及IL-1β表达,其机制可能和调节NF-κB的活性有关。
