    人生長(zhǎng)激素(Growth hormone,GH)是腺垂體嗜酸性細(xì)胞分泌的蛋白質(zhì)類激素,它的作用主要是促進(jìn)蛋白質(zhì)的合成代謝,增進(jìn)機(jī)體的生長(zhǎng)、發(fā)育.此外,還調(diào)節(jié)糖和脂肪的代謝.生長(zhǎng)素的作用,是促進(jìn)蛋白質(zhì)的合成,增進(jìn)全身各組織器官的生長(zhǎng),特別是明顯地促進(jìn)骨和軟骨組織的增長(zhǎng),突出表現(xiàn)身高的增長(zhǎng).這是由于生長(zhǎng)激素可直接促進(jìn)氨基酸由細(xì)胞外向細(xì)胞內(nèi)轉(zhuǎn)運(yùn),同時(shí)促進(jìn)細(xì)胞內(nèi)核糖核酸和去氧核糖核酸的合成,使蛋白質(zhì)生成增多,逐漸增加細(xì)胞的體積和數(shù)量,體現(xiàn)為生長(zhǎng).幼年期生長(zhǎng)激素分泌不足時(shí),產(chǎn)生侏儒癥;相反,分泌過(guò)多時(shí),則引起骨骼過(guò)分長(zhǎng)長(zhǎng),產(chǎn)生巨人癥.成年后,生長(zhǎng)激素分泌過(guò)多則易引起內(nèi)臟增大和短骨增粗,增長(zhǎng)等現(xiàn)象,臨床可見(jiàn)肢端肥大癥(與肥胖有一定區(qū)別).此外,生長(zhǎng)激素還有產(chǎn)生尿糖作用,主要是其能阻止葡萄糖進(jìn)入細(xì)胞內(nèi).
    下面就對(duì)人生長(zhǎng)激素的作用,發(fā)展,以及在醫(yī)學(xué)領(lǐng)域的應(yīng)用進(jìn)行討論與分析

    The life grows hormone(Growth hormone,GH) is the gland hangs a body to love the acidity cell secrete of protein hormone,it of function mainly is promote synthesize of protein metabolism,promote the growth,growth of machine body.In addition also regulate the metabolism of sugar and fat.Grow a plain function,is promote synthesize of protein,promote whole body each growth which organize organ,especially and clearly help bone and cartilage to organize of growth,the growth of outstanding performance height.This is because growth the hormone can directly promote the amino acids be transported inside cell by the cell extrovert and promote to check a sugar nucleic acid inside cell in the meantime and go to the oxygen check a synthesize of sugar nucleic acid,make protein born to increase,gradual increment cell of physical volume and amount,the body is a growth now.When childhood expected to grow hormone to secrete shortage,creation dwarf's disease;Contrary,secrete excessive,then cause skeleton excessively long long,creation giant disease.Grow hormone to secrete after become adult excessive then easily cause internal organs aggrandizement and short bone to increase thick,increase etc.phenomenon,clinical it is thus clear that the limb carries hypertrophy.(have with obese certain differentiation)In addition grow hormone to still have the creation urine the sugar function,mainly is that it can keep glucose from get into cell.
    Underneath to the life long function of hormone,development,and carry on discussion in the application of medical science realm and analytical
