摘要 目的观察艾司西酞普兰灌胃对抑郁症模型大鼠海马组织中5-羟色胺(5-HT)及5-HT1A受体表达的影响。方法将成年雄性SD大鼠60只分为对照组、模型组和治疗组各20只。模型组和治疗组给予慢性不可预性温和应激(CUMS)建立抑郁症模型,治疗组给予艾司西酞普兰灌胃。采用糖水偏好实验和Morris水迷宫实验进行行为学观察。每组取10只大鼠,1%戊巴比妥钠腹腔注射麻醉,断头取脑,冰上快速分离海马组织。采用高效液相色谱法测定海马组织中5-HT,Western blotting法检测5-HT1A受体表达。结果对照组、模型组、治疗组糖水偏好百分比分别为92.48%±8.18%、57.62%±4.90%、79.87%±2.96%,逃避潜伏期分别为(8.63±1.05)、(25.25±2.41)、(19.38±2.13)s,海马组织中5-HT分别为(1.92±0.22)、(0.34±0.07)、(0.88±0.11)ng/g,海马组织中5-HT1A受体相对表达量分别为0.74±0.07、0.16±0.01和0.37±0.04,上述指标三组间两两比较,P均<0.05。结论艾司西酞普兰灌胃可提高抑郁症大鼠海马组织中5-HT及5-HT1A受体表达水平。
