摘要 目的探讨N-甲基-D-天冬氨酸受体亚型(NR2B受体)拮抗剂艾芬地尔对七氟醚导致的幼年大鼠学习记忆能力损伤的保护作用及机制。方法出生后7 d的雄性SD大鼠随机分为四组:对照组(Con组)给予腹腔注射双蒸水10 mg/kg后暴露在30%氧气下4 h;艾芬地尔组(Ifen组)给予腹腔注射艾芬地尔(10 mg/kg)后暴露在30%氧气下4 h;七氟醚组(Sev组)腹腔注射双蒸水后暴露在2%七氟醚4 h;七氟醚+艾芬地尔组(Sev+Ifen组)给予腹腔注射艾芬地尔后暴露在2%七氟醚下4 h。用Western blotting、免疫荧光法检测大鼠海马区NR2B及凋亡相关蛋白半胱氨酸蛋白酶3(Caspase-3)、聚腺苷二磷酸核糖聚合酶(PARP)的表达。大鼠于出生后40 d行Morris水迷宫和避暗实验评估其学习记忆能力。结果与Con组及Sev+Ifen组比较,Sev、Ifen组NR2B、Caspase-3、PARP、Caspase-3阳性细胞百分比均升高(P<0.05或<0.01),Con组及Sev+Ifen组比较,P均>0.05。在定位航行实验中,Sev组的潜伏期于第2、3天长于Con组(P均<0.05)。空间探索实验中,各组目标象限的时间百分比比较差异无统计学意义(P均>0.05)。避暗实验结果表明,与Con组比较,Ifen、Sev组记忆潜伏期缩短(P均<0.05),Sev+Ifen组差异无统计学意义(P>0.05)。结论预先给予艾芬地尔可减少七氟醚对幼鼠学习记忆能力的损伤,其机制可能与抑制NR2B表达及其所诱导的细胞凋亡有关。
