摘　　要：以不同强度训练大鼠停训28周为对象,应用免疫组织化学技术,探讨运动对大鼠海马神经元细胞凋亡因子Bax、Bcl-2表达的影响.参照Bedford训练方案,建立起Sprague dawley(SD)大鼠有氧训练与疲劳训练动物模型,停训28周后,观察大鼠海马神经元Bax、Bcl-2的表达变化.结果表明:长期有氧训练大鼠老年期海马神经元Bcl-2/Bax比值升高,长期疲劳训练大鼠老年期海马神经元Bcl-2/Bax比值下降.这是因为长期有氧训练促进了大鼠海马神经元产生了良好的适应,对大鼠老年期海马神经元起到保护和延缓其衰老的作用.而长期疲劳训练会影响到大鼠老年期海马神经细胞的功能状态.The influence on the expression of Bax、Bcl-2 in the hippocampus neuron of stopping training 28 weeks rats is studied.Refered to the training scheme of Bedford,the training model of SD rats is established.All rats in the normal cage live 28 weeks and the expression change of Bax and Bcl-2 in the Hippocampus Neuron is observed.The results show that aerobic training promotes the ratio of Bcl-2/Bax in CA1 area and CA3 area of hippocampus,fatigue training restrain the ratio of Bcl-2/Bax in CA1 area and CA3 area of hippocampus after stopping training.It is analyzed that aerobic training has taken good care of the hippocampus neuron of the aged rats,fatigue training has effected the function of the hippocampus neuron of the aged rats.
