摘要 目的探讨规律运动对慢性心理应激大鼠海马锥体细胞形态的影响。方法建立慢性心理应激模型结合6周游泳训练后,采用HE染色和透射电镜技术观察海马锥体细胞形态和结构变化。结果应激组大鼠海马CA3区锥体细胞胞浆凝固、胞核固缩、染色质边集,核膜皱褶,核内外可见空泡变性,线粒体变性、嵴数量明显减少,粗面内质网模糊不清、网腔局部扩张;30min运动组与对照组相似,60min运动组较对照组轻度改变,应激+30min运动组变化介于对照组和应激组之间;应激+60min运动组与应激组相似。结论心理应激导致大鼠海马CA3区锥体细胞形态和超微结构改变,适量运动调节可减缓慢性心理应激引起的损伤,对海马锥体细胞有保护作用。
