Dopaminergic, adrenergic and serotoninergic neuroendocrine pathways also play an important role in the control of hGH secretion. Excitatory stimuli of hGH secretion include hypoglycemia, exercise, fasting, meals with a high protein content, deep sleep, stress, glucagon, L Dopa, amino acids, etc. Inhibitory stimuli include glucose, cortisol, hGH and free fatty acids. Because of its short plasma half life (±25 minutes) and of the frequent excitatory or inhibitory stimuli, hGH displays frequent and large variations of concentration in serum. One of the main physiological functions of hGH is to act on the liver and other tissues to produce Somatomedins, which in turn induce growth by direct action on target tissues. In contrast to hGH, the concentration of somatomedin in serum is kept stable by virtue of being largely bound to circulating plasma proteins. Growth retardation hGH hyposecretion is one of the various causes of small stature in children. Serum hGH measurement with a highly sensitive assay, especially following a provocative stimulus (absence of response), is an important way to establish this diagnosis because this group of patients can be treated by administration of hGH. Hypopituitarism Serum hGH measurement is also an index of pituitary function when hypopituitarism (either idiopathic or due to tumour and surgery) is suspected. Gigantism and acromegaly Serum hGH measurement, especially following a provocative inhibitory test (absence of response), is an important way to establish the diagnosis of hGH hypersecretion due to acidophilic pituitary tumour. This results in gigantism in children and acromegaly in *****s. Both of these disorders may be treated by surgery or radiation. 上海玉博生物技術(shù)有限公司在為生命科學(xué)領(lǐng)域提供豐富的產(chǎn)品與信息資源方面處于國內(nèi)**地位,公司提供的產(chǎn)品涵蓋了二十多個國家近五十萬種產(chǎn)品,而且產(chǎn)品的數(shù)量與信息在不斷的增長和更新,公司提供的產(chǎn)品能夠使生命科學(xué)工作者加快對生物化學(xué),分子生物學(xué),細胞生物學(xué)以及蛋白質(zhì)組學(xué)研究的認知,以及分子診斷和臨床醫(yī)學(xué)領(lǐng)域的應(yīng)用。
