  • 简介:摘要目的研究异氟醚对大鼠空间记忆及海马组织中载脂蛋白e(ApoE)阳性细胞表达影响。方法12月龄雄性wistar(350g)大鼠48只,随机分为三组(n=16),对照组(不麻醉,吸入30%氧气空氧混合气体),A组(异氟醚1.5%,连续吸入5d,每天3h),B组(异氟醚2%,连续吸入5d,每天2h)。各组大鼠在停药后1d取8只行Morris水迷宫进行认知功能测试,其余处死取海马组织,用免疫组织化学方法测定ApoE表达。结果各组大鼠异氟醚吸入过程中生命体征平稳,血氧饱和度及心率均在正常范围。A组和B组逃避潜伏期和游泳距离明显长于对照组(P<0.05),ApoE在A组和B组表达明显高于对照组(P<0.05)。结论多次吸入异氟醚对大鼠认知功能有所改变,可能与海马组织ApoE表达有关。
