Physiology of Growth Hormone Secretion
Growth hormone (GH) is secreted in a pulsatile fashion from the anterior pituitary gland. The synthesis and the secretion of GH are regulated mainly by two hypothalamic neuropeptides, the growth hormone-releasing hormone (GHRH) and somatostatin. A wide variety of physiologic and hormonal factors exert an effect on GH secretion. This paper will review physiology of GH secretion and the factors t...
متن کاملSelective impairment of growth hormone response to physiological stimuli.
In a consecutive group of 25 children with defective growth being evaluated for growth hormone deficiency, EEG-monitored slow-wave sleep provided discriminatory serum growth hormone responses equivalent to those obtained by arginine and insulin-hypoglycaemia provocation. Exercise was less effective but was able to provide a useful screening test. In 2 subjects with abnormal physiological but no...
متن کاملTests for growth hormone secretion.
Tests for growth hormone secretion SIR,-We were interested in the correspondence between Dr Addy and Professor Brook and Dr Hindmarsh on detecting organic illness through assessment of height velocity .' 2 The question, however, is academic and their arguments theoretical since, as we have recently shown, the assessment of height velocity in individuals is so imprecise as to be clinically meani...
متن کاملTests for growth hormone secretion.
Tests for growth hormone secretion SIR,-Professor Brook and Dr Hindmarsh claim that children growing at a less than 3rd centile velocity carry a 97% chance of showing an abnormality on investigation.' In a leading article in the British Medical Journal in 1986 they wrote 'If a third centile velocity is chosen for immediate action the chances of investigating a normally growing child are only 3%...
متن کاملFasting enhances growth hormone secretion and amplifies the complex rhythms of growth hormone secretion in man.
Studies in man have shown that the episodic release of growth hormone (GH) is infrequent and erratic, and unlike that in the rat does not appear to have discernible ultradian periodicities. However, these observations in nonfasted subjects may be invalid since mixed nutrients have unpredictable effects on GH release. Moreover, in the fed state basal GH levels are frequently undetectable, thus r...
