摘要 目的探讨阿托伐他汀预处理对SD大鼠局部脑缺血再灌注损伤IL-1β表达的影响。方法 90只健康雄性SD大鼠随机分成假手术组、对照组、阿托伐他汀组(30只/组)。各组按缺血2h再灌注0、2、6、12、24h分为5个亚组,每个亚组6只。对照组和阿托伐他汀组均采用改良Longa-Zea氏线栓法制备SD大鼠右侧大脑中动脉闭塞的脑缺血再灌注模型。免疫组化法检测IL-1β的表达。结果假手术组仅见少量IL-1β阳性表达细胞,各时间点无差异。脑缺血2h后,随再灌注时间延长,阿托伐他汀组较对照组IL-1β阳性表达细胞数减少,再灌注6、12和24h两组间比较差异有统计学意义(P<0.05或P<0.01)。结论预防性应用阿托伐他汀能减少SD大鼠局部脑缺血再灌注损伤中缺血侧海马区IL-1β的表达。
