Human body ' s modulation for the surrounding . the true meaning of the gene engineering to express the hgh is therapy of the dwarf and ectogenesis complementation to promote the blood hgh when the atrophy of old people ' s pituitary gland begins 基因工程表达人生长激素的主要意义也在于其除了能治疗侏儒症等先天遗传性疾病外，在老年人垂体萎缩的情况下，可作外源性补充，提高逐渐下降的血中生长激素的浓度。
Human growth hormone ( hgh ) is a kind of important polypeptide produced by the anterior portion of the pituitary gland , which could facilitate the growth of the bone and promote the metabolism of the organism . and the maintenance of blood hgh level is vital for the normal growth and 人生长激素是人垂体前叶分泌的重要激素，具有刺激骨骼生长和促进体内代谢的重要作用，其血中浓度的维持对机体适应环境和正常成长极为重要。
It " s shown from the results that the pituitary gland of silurus asotus originates from two embryonic cells of different position ; and the doral wall of the original cavum oris forms the rostral pars distali ( rpd ) and the proximal pars distalis ( ppd ) ; the infundibulum of the ventral part of diencephalons forms the the pars intermedia ( pi ) and the neurohypophsis 结果表明：鲇脑垂体由两个不同部位的胚胎细胞形成，原始口腔背壁外胚层分离出来的细胞构成腺垂体的前外侧部( rpd )和中外侧部( ppd ) ，从间脑腹面漏斗体分离出来的细胞构成腺垂体中间部( pi )及神经垂体( nh ) 。
After dna analysis , six white pigs is not present chimerism in various tissues . to one skin pigment piglet , chimerism is present in skin , brain , pancreas , pituitary gland and blood , but not in heart , lung , liver , spleen , kidney , intestine and ovary . the detection of another skin - pigment chimera is similar to the analysis result of wzsp 通过dna分析进一步得出，所产8头仔猪，其中六头白猪体组织未发现嵌合现象；其中一头皮肤色素嵌合体猪的皮肤、大脑、胰、甲状腺、血是嵌合的，而心、肺、肝、脾、肾、空肠、卵巢这些组织并没有嵌合；另一头皮肤色素嵌合体猪的检测结果和五指山猪取得相似的结果。
Such biochemical communication develops and is managed by the thymus and pituitary glands , and includes messages to increase or decrease the metabolism along with when to produce more blood cells or varying kinds , along with a host of chemistry required for neural function along with limbic function 这类生化通讯发展并由胸腺和脑垂体管理，包括了来促进或减缓新陈代谢，以及何时来制造更多血细胞或其它细胞的信息，并带有一系列要获得神经功能及脑边缘功能所需的化学物质。
In order to investigate the ontogeny of the pituitary prolactin ( prl ) expression of sheep fetuses during gestation , the pituitary glands were collected at days 60 , 90 , 120 of gestation , the first day after birth , respectively . the cells containing the prolactin ( prl ) were detected using immunohis ' ochemistry method 为了研究绵羊胎儿垂体中催乳素细胞( lactotrophs )的发育和功能变化，分别在胎儿发育的第60 、 90 、 120天和出生期采集垂体，利用免疫组织化学方法研究了垂体中催乳素( prolactin ， prl )的表达及其变化。
