A 10-year-old child with idiopathic growth hormone deficiency was treated with recombinant methionyl human growth hormone (m-hGH, Somatonorm) at a dose of 14 IU/week. Height increased from 122.3 to 126.5 cm during the first 9 months of treatment (5.6 cm/y), but only from 126.5 to 126.6 cm during the next 3 month of treatment (0.4 cm/y). Anti-hGH antibody was detected at 2 months of treatment, r...

479 INTRODUCTION Growth hormone has been used in the treatment of short stature since 1957 . Prior to 1985, human cadaver-derived pituitary growth hormone was used. Recombinant human growth hormone which was approved in 1985 made available a reliable, virtually unlimited resource to replace human pituitary growth hormone (which was withdrawn due to reported cases of Creutzfeldt-Jakob disease). ...

Human pancreatic growth hormone releasing factor (hpGHRF(1-40] stimulates the release of growth hormone in normal subjects and some patients with growth hormone deficiency. A study comparing the shorter chain amidated analogue hpGHRF(1-29) with an equivalent dose of hpGHRF(1-40) in seven normal subjects showed no significant difference in growth hormone response between the two preparations. Si...

A 31-year-old female bodybuilder who was admitted to the Clinic because of deep coma and hypoglycaemia was presented. For last six weeks she had been preparing for a competition doing aerobic and anaerobic exercises, ingesting rich-protein and low-carbohydrate diet and administering a low dose of somatotropin every day. Even for the regional competitions there is a need for exact doping check a...

The location of renin (EC 3.4.99.19) in rat pituitary was determined by the peroxidase-antiperoxidase immunohistochemical technique. By using antisera prepared with purified rat renal renin, an immunoreactive substance was localized within ovoid cells scattered throughout the anterior pituitary. These cells were shown to be luteinizing hormone-producing cells by staining with anti-luteinizing h...

Research on the health-related quality of life (HrQoL) impact of short stature and its treatment in children and adolescents has developed recently. Based on a PubMed literature search, studies addressing this issue were identified and considerable methodological problems mainly related to the HrQoL instruments used and conflicting results are discussed in this mini review. Additionally, this m...

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...

Chronic treatment of growing pigs with porcine somatotropin (pST) promotes protein synthesis and doubles postprandial levels of insulin, a hormone that stimulates translation initiation. This study aimed to determine whether the pST-induced increase in skeletal muscle protein synthesis was mediated through an insulin-induced stimulation of translation initiation. After 7-10 days of pST (150 mic...

The primary purpose of this experiment was to assess the possible beneficial effects of recombinant equine somatotropin (reST) administration on wound healing in adult geldings. The effects of the 21-d reST treatment on carbohydrate and lipid metabolism and on endogenous ST characteristics were monitored as well. Single, full-thickness skin incisions (7.62 x 7.62 cm) were made in the pectoral r...

The development of muscle in vitro from embryonic presumptive myoblasts is known to have complex nutritional requirements.' One of the necessary ingredients for myogenesis in vitro, and indeed for the growth of many cell types, is serum. During the course of studies aimed at understanding the mechanisms involved in the fusion of myoblasts, it became of interest to delete serum from the medium a...
