The production of milk depends upon stimulation of the breasts . when baby suckles , messages are sent to your brain which then releases two hormones : prolactin and oxytocin 母乳的分泌量要根据乳房的激发程度来看。当婴儿吮吸时，信息就会被传输到大脑里，而大脑便释放出两颗荷尔蒙因子，那便是泌乳素和催产素。
What it does : secreted by the pituitary gland , oxytocin stimulates the prostate , causes muscle contractions and sensitizes nerves . research has shown that increased oxytocin produces more intense orgasms 催产素由脑垂体分泌，能刺激前列腺，让肌肉收缩，神经处于敏感状态。研究表明催产素分泌增加可以使得性高潮更强烈。
The hormones vasopressin ( antidiuretic hormone , or adh ) and oxytocin made in the hypothalamus ( supraoptic and paraventricular nuclei ) are transported into the intra - axonal neurosecretory granules where they are released 下丘脑（视上核和室旁核）形成的血管加压素(抗利尿激素， adh )和催产素以神经内分泌颗粒的形式经轴突运送至神经垂体得以释放。
The present results indicated that the paraventricular nucleus of the hypothalamus and the supraoptic nucleus might have important roles in neuroimmunomodulation . 2 . following lps or seb was administered intraperitoneally , the expression of pcna of splenic cells and il - 1 receptor type i in pvn and son were observed by using immunocytochemistry in the mice . double fluorescent labeling technique was used to determine the relationship of il - 1 receptor type i co - expressions with arginine vasopressin or oxytocin 二、小鼠腹腔内给予细菌内毒素lps或肠毒素seb ，用免疫组织化学方法观察了脾脏核增殖抗体及下丘脑室旁核和视上核中1型il 1受体的表达，并采用双标记技术观察了1型il刁受体阳性神经元和加压素及催产素表达的关系。
Abstract : in order to clarify the location of the center for synchronized milk - ejection bursts of magnocellular oxytocin neurons in the hypothalamus , the bursts of these neurons were recorded extracellularly in lactating rats with selectively - cutting lesions of the middle brain or hypothalamus 文摘:为探究授乳大鼠双侧下丘脑巨细胞催产素神经元同步化射乳反射爆发放电的中枢所在,我们采用双微电极细胞外记录技术,观察了选择性脑切割损毁后的大鼠双侧视上核内催产素神经元在仔鼠吸吮刺激下射乳反射爆发放电。
The expressions of il - 1 receptor type i in mouse brain were widely distributed . and the expressions in mouse pvn and son were significantly enhanced by an intraperitoneal administration of lps or seb ( p < 0 . 05 or 0 . 01 ) . the arginine vasopressin - and oxytocin - containing neurons in the pvn and son also displayed immunofluo - rescence labeling for il - 1 receptor type i F0刀1 ） ； i型il 1受体在正常小鼠脑内的表达很广泛，与对照组比较， lps或seb引起1型几l受体在小鼠下丘脑室旁核和视上核中表达显著增强（ o
