| iPTH | immunoassay for parathyroid hormone; immunoreactive parathyroid hormone |
|---|---|
| LHRH, LH-RH | luteinizing hormone-releasing hormone |
| LHRHR | luteinizing hormone-releasing hormone receptor |
| LRH | luteinizing hormone-releasing hormone |
| LSH | lutein-stimulating hormone; lymphocyte-stimulating hormone |
| hypophysiotropic hormone | A hormone that stimulates the rate of secretion of hypophysial hormone's; e.g., a releasing factor. (05 Mar 2000) |
|---|---|
| somatotropic hormone | <protein> Hormone (191 amino acids) released by anterior pituitary that stimulates release of somatomedin, thereby causing growth. (18 Nov 1997) |
| somatotropin release-inhibiting hormone | <protein> Gastrointestinal and hypothalmic peptide hormone (two forms: 14 and 28 residues), found in gastric mucosa, pancreatic islets, nerves of the gastrointestinal tract, in posterior pituitary and in the central nervous system. Inhibits gastric secretion and motility: in hypothalamus/pituitary inhibits somatotropin release. (18 Nov 1997) |
| somatotropin-releasing hormone | <chemical> Hypothalamic peptide that regulates the synthesis and secretion of somatotropin in the anterior pituitary gland. Chemical name: Somatoliberin (12 Dec 1998) |
| natriuretic hormone | <chemical> A low-molecular weight substance, possibly from the hypothalamus, which is released due to plasma volume expansion. It causes natriuresis in part by inhibiting sodium potassium atpase. The development of hypertension may be the consequence of an abnormality in volume regulation induced by a defect in the renal response to the natriuretic effect of the natriuretic hormone. Do not confuse with atrial natriuretic factor or cardionatrin which is a different, well characterised hormone. Chemical name: Natriuretic factor (12 Dec 1998) |
| neoplasms, hormone-dependent | Certain tumours that 1) arise in organs that are normally dependent on specific hormones and 2) are stimulated or caused to regress by manipulation of the endocrine environment. (12 Dec 1998) |
| steroid hormone | <endocrinology> A group of structurally related hormones, based on the cholesterol molecule. They control sex and growth characteristics, are highly lipophilic and are unique in that their receptors are in the nucleus, rather than on the plasma membrane. Examples: testosterone, oestrogen. (18 Nov 1997) |
| sympathetic hormone | <protein> A neurohormone, such asepinephrine, produced in response to stimulationof the sympathetic nervous system and which acts as a chemical mediator invarious organs. (09 Oct 1997) |
| syndrome of inappropriate secretion of antidiuretic hormone | Continued secretion of antidiuretic hormone despite low serum osmolality and expanded extracellular volume. (05 Mar 2000) |
| inappropriate hormone | A hormone formed by tissue outside the normal endocrine site of production; e.g., adrenocorticotropic hormone produced by a bronchogenic carcinoma. Synonym: inappropriate hormone. (05 Mar 2000) |
| interstitial cell-stimulating hormone | <protein> Synonym for luteinising hormone. (18 Nov 1997) |
| oestrogenic hormone | <pharmacology> A female hormone produced by the ovaries (or an equivalent hormone synthesised in the laboratory). Oestrogen deficiency can lead to osteoporosis. (12 Dec 1998) |
| ovarian hormone | <protein> Polypeptide hormone produced by corpus luteum and found in the blood of pregnant animals. Acts, as its name suggests, to cause muscle relaxation during parturition. Human relaxin has an A chain of 24 amino acids and a B chain of 29. Has structural similarity to insulin. (18 Nov 1997) |
| thymic hormone | <endocrinology> One of the hormones produced by the thymus that are believed to play a role in the maturation of T-lymphocytes and overall modulation of the immune system. Versions of several of them are under study as anti-HIV therapies-thymopentin and thymosin-a1 in particular. (09 Oct 1997) |
| ectopic hormone | A hormone formed by tissue outside the normal endocrine site of production; e.g., adrenocorticotropic hormone produced by a bronchogenic carcinoma. Synonym: inappropriate hormone. (05 Mar 2000) |
