摘要 目的了解雌激素和姜黄素对海人酸(kainic acid,KA)杏仁核点燃大鼠癫痫发作的影响。方法给去势的雌性大鼠添加雌激素治疗,添加姜黄素治疗,或添加雌激素和姜黄素治疗,比较各组大鼠致痫后癫痫发作的行为学、脑电图和海马神经元损伤的变化。结果给雌激素治疗的大鼠重型发作(Racine 4/5级)评分最高,而雌激素加姜黄素治疗组评分最低(P<0.05)。脑电图的变化与行为学的改变基本一致。致痫后大鼠注射KA侧海马CA3区、CA4区可见到明显的细胞损伤,而该侧海马CA1区、齿状回区(DG)及对侧海马CA3区、CA1区及DG区神经元损害不明显。雌激素组大鼠双侧海马CA3区均出现加重的神经元损害,姜黄素组及雌激素加姜黄素组大鼠海马注射对侧CA3区存活神经元较雌激素组明显增加(P<0.01)。结论高水平的雌激素可以加重癫痫的发作,给姜黄素治疗可以减轻大鼠海马CA3区神经元损害。
