摘要 目的探讨吲哚美辛预处理对大鼠脑缺血再灌注后脑组织白介素-1β(IL-1β)和C反应蛋白(CRP)表达的影响及作用机制。方法成年雄性SD大鼠共84只,随机分成3组,为假手术组、脑缺血再灌注模型组及吲哚美辛预处理组,每组有28只。大鼠大脑中动脉局灶性脑缺血模型通过用改良Longa线栓法来制备。对每组动物于缺血2 h行再灌注,于再灌注6、12、24、48 h进行神经功能评分,并应用免疫组化法检测IL-1β及CRP的表达。结果与对照组相比,模型组大鼠局灶性脑缺血再灌注后缺血脑组织中IL-1β及CRP含量增加(P<0.05);与模型组相比,吲哚美辛预处理组IL-1β及CRP的含量减少(P<0.05),神经功能缺损评分降低(P<0.05)。结论吲哚美辛对大鼠局灶性脑缺血再灌注损伤有脑保护作用,其作用机制可能与抑制脑内IL-1β及CRP的表达有关。
