More prolactin ( milk producing hormone ) is produced at night , so breastfeeding expression at night is especially helpful for keeping up the milk supply 催乳素（帮助乳汁分泌的荷尔蒙）在晚间分泌较多，所以夜间喂哺婴儿挤奶对维持母乳分泌很有帮助。
In order to stimulate & maintain lactation , it is advisable to give breastfeeding at night , while adjusting yourself to sleep or rest whenever your baby sleeps 为了刺激和维持乳汁的产生，晚上喂母乳是很重要的，因为“催乳素”的分泌水平在晚上相对较高。
Levels of two other hormones associated with pregnancy ? chorionic somatomammotropin and pregnancy - associated glycoprotein ? were also far lower than they should have been 另外两种与妊娠相关的激素? ?绒毛膜生长催乳素与妊娠相关糖蛋白的水平也远低于它们应有的水平。
Anteriorticrticotrophic ( acth ) cell and prolactin ( prl ) cell in rpd do not differentiate until the larva got 15 - day old . blood capillary begins to spread inside the pituitary gland 15日龄稚鱼脑垂体ppd内的促肾上腺皮质素分泌细胞( acth )及催乳激素分泌细胞( prl )已分化，腺垂体内开始出现毛细血管。
Though pituitary adenomas are benign , they can produce problems either from a mass effect ( usually visual problems from pressing on the optic chiasm and / or headaches ) or from production of hormones such as prolactin or acth 尽管垂体腺瘤是良性的，但也能引起肿块压迫的后果：因压迫视交叉引起视力障碍、 、头痛、产生催乳素acth等。
Berman for bump you love dandle fecundity ' nutritional requirements custom - made product up , contain extra nutrient substance multiplicable male and female pet fecundity ， increase sack superfoetation 伯曼为提高您爱宠繁殖力的营养需求定做的产品，含有额外营养物质可增加雌雄宠物的繁殖力，增加宠物一包多胎，仔仔个个身体健康，同时对雌宠物有催乳效果。
We investigated the cell - specific expression of gnrhr in the swine pituitary by coimmunolocalization . the result reveal that about 90 % somatotrophs and 10 % lh - immunopositive gonadotrophs express gnrhr and there is no gnrhr expression in the thyrotrophs , lactotrophs and corticotrophs 结果表明，约90的生长激素细胞和10的表达lh的促性腺激素细胞表达gnrhr ；而促甲状腺激素细胞、催乳素细胞和促肾上腺皮质激素细胞没有gnrhr的表达。
Therefore , we have determined the structure of 20ahsd ge ne and isolated the genomic fragments encoding its promoter region to verify the cis - acting dna response elements and trans - acting factor , which are involved in hormone regulation on 20ahsd gene expression in our research work 20 hsd的调控区基因结构以及哪些顺式元件和反式作用因子在起作用尚不完全清楚，催乳素( prl )和绒毛膜促性腺激素( cg )调节20 hsd表达的分子机制，尚未见国内外文献报道。
The localization and expression of prolactin receptor from inner mongolia alpas cashmere goat were studied by sacpic staining , in situ hybridization and western blotting . samples of skin were taken at interval three months from birth , three months old , six months old , nine months old , ten months old or twelve months old , which correspond to summer , autumn , winter and spring . paraffin sections of hair follicles were stained with sacpic staining and in situ hybridization . the protein of prolatin receptor is abstracted from samples of skin in order to study on expression of prolactin receptor . there are prolactin receptors in outer root sheath , dermal papilla and inner root sheath . the growth of primary follicle is continuous 本实验从绒山羊出生后每隔三个月采一次皮样，共分为4个月龄( 3 、 6 、 9 、 10或12 )段，通过制作石蜡切片，原位杂交、染色，并提取皮样蛋白做westernblotting等实验研究方法，研究了催乳素受体mrna催乳素受体在不同生长季节的内蒙古阿尔巴斯白绒山羊皮肤毛囊中的定位与表达，染色结果发现阿尔巴斯白绒山羊初级毛囊全年持续生长，次级毛囊的生长情况随季节而变化，秋冬季生长旺盛，夏季生长缓慢与绒毛生成规律呈正相关。
The growth of the second follicle is vary by season . in autumn and winter , the speed of the growth of the second follicle is quick . in summer , that of the growth of the second follicle is slow . lt is same as the growth of cashmere . the weight of prolactin receptor is 87kd and 71 kd . the qualitity of prolactin receptor . is vary by season Westernblotting结果显示催乳素受体蛋白的分子量有87kd和71kd二种；催乳素受体蛋白的含量变化与绒纤维的生长情况呈正相关。原位杂交结果表明催乳素受体mrna分布在毛囊的外根鞘、内根鞘。
