摘要: 目的:观察帕罗西汀对心理应激大鼠下丘脑c-fos 表达的影响, 以揭示帕罗西汀治疗心理应激引起焦虑的分子作用机制。方法:建立大鼠心理应激模型, 观察抗焦虑药物帕罗西汀用药组大鼠血浆皮质醇和下丘脑c-fos 的表达。结果:与正常对照组比较, 各应激组大鼠血浆皮质醇含量明显升高, 下丘脑室旁核c-fos 表达显著增加, 而帕罗西汀单次、连续给药能减少应激大鼠血浆皮质醇含量和下丘脑室旁核c-fos 表达。结论:帕罗西汀通过抑制c-fos 基因表达, 下调下丘脑垂体肾上腺轴(HPA 轴) 水平, 从而发挥中枢应激调节作用。

Abstract: AIM: To study the effects of paroxetine on the psychological stress induced by c-fos gene expression in the rat hypothalamus paraventricular nucleus (PVN) and to explore the molecular mechanism of effects of paroxetine on the stress related anxiety disorders. METHODS: The rat psychological stress model was made by restraint stress.The cortisol was analyzed by radioimmnoassay, and expression of c-fos positive cells was detected by S-P immunohistochemical assay in the rat PVN.RESULTS: The level of cortisol and the expression of c-fos positive cells increased more significantly in the other groups than that in the control group, but decreased in the paroxetine group.The paroxetine reduced the level of cortisol and inhibited the expression of c-fos positive cells in the PVN after psychological stress. CONCLUSION: The paroxetine can regulate the nerve centre by alleviating the expression of the c-fos in the hypothalamus paraventricular nucleus(PVN) and the activation of HPA pathway.
