| PTH/PTHrP | Parathyroid hormone/parathyroid-hormone-related peptide |
| melanocyte-stimulating hormone | <endocrinology> A releasing hormone produced in the mammalian hypophysis and related structures in lower vertebrates. Made up of _ MSH (1665D), the same as amino acids 1-13 of ACTH and _ MSH (18 amino acids, 22 in humans). Causes darkening of the skin by expansion of the melanophores but its role in mammals is unclear. Synonym: melanotropin. Acronym: MSH (22 Sep 2002) |

| melanotropin release-inhibiting hormone | Inhibits synthesis and release of melanotropin. Synonym: melanotropin release-inhibiting hormone. Origin: melanotropin + G. States, stationary, + -in (05 Mar 2000) |
| melanotropin-releasing hormone | A hexapeptide similar to oxytocin; it stimulates the release of melanotropin. Synonym: melanotropin-releasing factor, melanotropin-releasing hormone. Origin: melanotropin + L. Libero, to free, + -in (05 Mar 2000) |
| peptide hormone inactivating endopeptidase | <enzyme> From xenopus laevis; cleaves at xaa-phe, xaa-leu or xaa-ile bonds where xaa = ser, phe, tyr, his or gly in peptide hormones Registry number: EC 3.4.24.- Synonym: phie, xenopus (26 Jun 1999) |
| gonadotrophin-releasing hormone | <hormone> The peptide hormone that control reproductive function. It produced and released by the hypothalamus and controls the production and release of gonadotrophins from the pituitary gland. It causes the production of luteinising hormone and follicle-stimulating hormone. Synonym: gonadotropin-releasing factor, gonadotropin-releasing hormone, luteinizing hormone/follicle-stimulating hormone-releasing factor, gonadoliberin. Origin: Gonad + L. Libero, to free, + -in (19 Sep 2002) |
| gonadotropic hormone | <endocrinology, hormone> A hormone capable of promoting gonadal growth and function. The effects are usually limited to discrete functions or histological components of a gonad, such as stimulation of follicular growth or of androgen formation. Most gonadotrophin's exert their effects in both sexes, although the effect of a given gonadotrophin will differ in males and females. Synonym: gonadotropin, gonadotropic hormone. Origin: for gonadotrophin, fr. Gonad + G. Trophe, nourishment (12 Sep 2002) |
| gonadotropin-releasing hormone | <hormone> The peptide hormone that control reproductive function. It produced and released by the hypothalamus and controls the production and release of gonadotrophins from the pituitary gland. It causes the production of luteinising hormone and follicle-stimulating hormone. Synonym: gonadotropin-releasing factor, gonadotropin-releasing hormone, luteinizing hormone/follicle-stimulating hormone-releasing factor, gonadoliberin. Origin: Gonad + L. Libero, to free, + -in (19 Sep 2002) |
| growth hormone | <endocrinology, hormone> Polypeptide (191 amino acids) produced by anterior pituitary that stimulates liver to produce somatomedins 1 & 2. (13 Nov 1997) |
| growth hormone-producing adenoma | <tumour> An adenoma that produces the clinical picture of gigantism or acromegaly, although a third of the cells have no granules or are a mixture of acidophils and chromophobes; some tumours may secrete both growth hormone and prolactin; often an acidophil or eosinophil adenoma. (05 Mar 2000) |
| growth hormone-releasing factor | <endocrinology> Peptide hormone related to the glucagon family, released from the pituitary, acts on the adenohypophysis to release growth hormone. Synonym: somatoliberin, growth hormone-releasing factor. (20 Sep 2002) |
| growth hormone stimulation test | <investigation> A test which measures the level of human growth hormone in response to the administration of the amino acid arginine. This test measures the ability of the pituitary gland to secrete growth hormone. Normal values in children are: 48 ng/ml. Normal values in men are 10 ng/ml. Normal values in women are 15 ng/ml. This test is used to evaluate infants with growth retardation. It may also be part of an evaluation for a pituitary tumour. Failure of arginine to raise growth hormone levels may indicate hypopituitarism or dwarfism. (27 Sep 1997) |
| growth hormone suppression test | <investigation> A test to determine if growth hormone is suppressed by hyperglycaemia. Growth hormone blood levels are determined sequentially after ingestion of a glucose-rich meal. If growth hormone levels remain elevated (after the glucose is given) then acromegaly or gigantism is suspected. (27 Sep 1997) |
| chorionic gonadotrophic hormone | A glycoprotein with a carbohydrate fraction composed of d-galactose and hexosamine, extracted from the urine of pregnant women and produced by the placental trophoblastic cells; its most important role appears to be stimulation, during the first trimester, of ovarian secretion of the oestrogen and progesterone required for the integrity of conceptus; it appears to play no significant role in the last two trimesters of pregnancy, as the oestrogen and progesterone are then formed by the placenta. Synonym: anterior pituitary-like hormone, choriogonadotropin, chorionic gonadotropic hormone, chorionic gonadotrophic hormone, placenta gonadotropin, placentagonadotropin. (05 Mar 2000) |
| chromatophorotropic hormone | See: melanotropin. (05 Mar 2000) |
| pituitary gonadotropic hormone | Any gonadotropin of hypophysial origin; formerly used to designate a single hormone, because it was thought that the anterior hypophysis secreted only one gonadotropin. Synonym: pituitary gonadotropic hormone. (05 Mar 2000) |
