【摘要】：目的探討抗抑郁劑鹽酸帕羅西汀對卵巢切除大鼠學習記憶能力、血清雌激素水平及大鼠海馬雌激素受體表達的影響。方法采用SD雌鼠雙側卵巢切除(OVX)作為雌激素波動引起的抑郁與認知障礙模型,用Morris水迷宮實驗來測試大鼠的學習記憶功能。實驗共分為正常對照組、OVX對照組、OVX藥物組。予5-羥色胺重攝取抑制劑類藥物:鹽酸帕羅西汀10 mg/(kg·d)干預4周。采用ELISA法測量SD大鼠血清黃體生成素、卵泡刺激素、雌激素。免疫組化法檢測大鼠海馬雌激素受體α(ERα)和雌激素受體β(ERβ)的陽性細胞表達數(shù)。結果 1 Morris水迷宮實驗中,OVX對照組和OVX藥物組的逃避潛伏期明顯縮短,停留在平臺時間百分比明顯增加。2 OVX藥物組的血清雌激素較OVX對照組明顯增加(P0.05)。3藥物組與非藥物組的ERα、ERβ表達無明顯差異。結論帕羅西汀增加OVX大鼠血清雌激素水平和改善學習記憶能力,而對海馬ERα、ERβ表達無明顯影響。
[Abstract]:Objective to investigate the effects of paroxetine hydrochloric acid on learning and memory ability, serum estrogen level and estrogen receptor expression in hippocampus of ovariectomy rats. Methods bilateral ovariectomy (OVX) was used as a model of depression and cognitive impairment induced by estrogen fluctuation in SD female rats. Morris water maze test was used to test the learning and memory function of rats. The experiment was divided into normal control group, OVX control group and OVX drug group. 5-hydroxytryptamine reuptake inhibitor: paroxetine hydrochloric acid 10 mg/ (kg 路d) was given for 4 weeks. Serum luteinizing hormone, follicular stimulating hormone and estrogen were measured by ELISA method in SD rats. The expression of estrogen receptor 偽 (ER 偽) and estrogen receptor 尾 (ER 尾) in rat hippocampus was detected by immunohistochemistry. Results 1 in Morris water maze test, the escape latency of OVX control group and OVX drug group was significantly shortened and the percentage of staying on the platform was significantly increased. 2 the serum estrogen level in OVX drug group was significantly higher than that in OVX control group (P 0.05). 3 there was no significant difference in the expression of ER 偽 and ER 尾 between drug group and non-drug group. Conclusion Paroxetine increases serum estrogen level and improves learning and memory ability in OVX rats, but has no significant effect on the expression of ER 偽 and ER 尾 in hippocampus.
