To a great extent, animal growth is regulated by the pituitary gland and its secretions of growth hormone (somatotropin). Implants work by increasing (via the pituitary gland) growth hormone and insulin at the cellular level, which results in increased synthesis of muscle tissue and, frequently, reduced deposition of body fat. This causes a measurable increase in growth rate and improved feed e...

introduction turner syndrome is the most common chromosomal abnormality in females. girls with turner syndrome have an abmormal or missing x choromosme that causes short stature, ovarian failure, renovascular and cardiac anomalies. it has been shown that there is a tendency to obesity in the turner syndrome. this prospective study has been done to evaluate whether body mass index (bmi) is diffe...

The role of pituitary growth hormone during fetal and neonatal life remains uncertain even though it has been demonstrated repeatedly that hypophysectomy of the juvenile animal severely retards or arrests growth. The claim has been made that administration of growth hormone to normal pregnant rats stimulates growth of the fetus (2-5), but the evidence presented is inconclusive. In man, the macr...

introduction: ghrelin increases growth hormone secretion and food intake. growth hormone (gh), steroid hormones and opioids are involved in the regulation of food intake. so, they may have a role in the regulation of ghrelin secretion. we determined the effect of intravenous injections of progesterone, gh and morphine or co-administration of these hormones on ghrelin concentration and body weig...

the growth hormone gene could be an attractive candidate gene for milk production in goats. single-strand conformation polymorphism was used to identify polymorphism at the goat growth hormone (ggh) gene. for this purpose, genotyping of 90 talli goat breeds was performed. nine conformational patterns were observed in exon 4 of the ggh gene, with frequencies of 27.7% for the homozygous pattern (...

Cultured rat pituitary cells (GC) respond to thyroid and glucocorticoid hormones by increases in growth hormone production and growth hormone mRNA. When these cells are transferred from medium containing normal animal serum (with 1.8 mug of thyroxine per dl) to a medium containing serum from a thyroidectomized calf, "hypothyroid medium" (with no detectable thyroid hormone), growth hormone produ...
