摘要 目的探讨头孢曲松钠对局灶性脑缺血大鼠脑组织Fas和NF-κB蛋白表达的影响。方法选用健康雄性Sprague-Dawley大鼠24只,体质量(280~320)g,随机分为假手术组、单纯脑缺血组和头孢曲松钠预处理组,头孢曲松钠预处理组于术前7 d腹腔注射头孢曲松钠,200 mg·kg-1·d-1。采用线栓法制备大脑中动脉阻塞(MCAO)的局灶性脑缺血大鼠模型,缺血后24 h后处死大鼠,应用免疫组化法检测大鼠脑组织Fas和NF-κB蛋白的表达。结果与假手术组比较,单纯脑缺血组大鼠脑组织的Fas和NF-κB p65免疫组化阳性细胞数显著增多(P<0.05);与单纯脑缺血组比较,头孢曲松钠预处理组大鼠脑组织的Fas和NF-κB p65免疫组化阳性细胞数明显减少(P<0.05)。结论头孢曲松钠具有抑制局灶性脑缺血大鼠脑组织Fas和NF-κB蛋白表达的作用。
