Results ①Compared to sham group, ISH and IHC of rat hypothalamic CRHshow positive cells numbers increase, positive areas enlarge and average gray scaledecreases, which reveals the expression of hypothalamic CRH neurons enhances afterPX;②The enhancement of ISH and IHC of hypothalamic CRH in PX rats aftermelatonin supplementation dose-dependently recovers, but it can't return to be normaleither in high dose group or in low dose group and either at 4th week or at 8th week;③IHC of CRH in median eminence of neurohypophysis shows positive areas enlargeand average gray scale decreases, which reveals the releasing of CRH fromhypothalamic CRH neurons increases;④ELISA of CRH in serum shows thedifferences of CRH concentrations among all groups are not significant, which indicates PX and melatonin supplementation have no significant effect on CRH levels.

结果： ①松果体摘除后大鼠下丘脑室旁核CRH 原位杂交和免疫组化的结果与假手术对照组相比均显示阳性细胞数增多、阳性面积增加、平均灰度降低，提示松果体摘除后下丘脑CRH 神经元的表达增强；②松果体摘除大鼠补充褪黑素后，下丘脑CRH 原位杂交和免疫组化染色增强呈剂量依赖性恢复，不过不论是低剂量组还是高剂量组，也不论是术后4 周还是术后8周，均不能恢复至正常；③松果体摘除后神经垂体正中隆起CRH 免疫组化结果显示阳性面积增加、平均灰度降低，提示下丘脑CRH 神经元释放CRH 增加；④ELISA 法检测血清CRH结果示各组血清CRH 浓度差异没有显著性，表明松果体摘除及补充褪黑素对血清CRH 水平没有显著影响。
