| 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) |
|---|
| syndrome of inappropriate secretion of antidiuretic hormone | Continued secretion of antidiuretic hormone despite low serum osmolality and expanded extracellular volume. (05 Mar 2000) |
|---|---|
| Syndrome of Inappropriate ADH | <endocrinology, syndrome> Inappropriate antidiuretic hormone secretion produces a disorder of fluid and electrolyte balance which results in the inability to excrete dilute urine. Inappropriate antidiuretic hormone secretion is seen in association with certain cancers (for example oat cell lung cancer, pancreatic, prostate, Hodgkin's disease), central nervous system disorders, head injury, myxoedema, psychosis and certain drugs. Symptoms include weight gain, nausea, vomiting, muscle cramps, confusion and convulsions. Incidence: approximately 1 in 100,000. Acronym: SIADH (18 Nov 1997) |
| inappropriate ADH syndrome | <syndrome> Hyponatraemia and renal salt loss attributed to overexpansion of body fluids resulting from sustained release of antidiuretic hormone despite the absence of appropriate stimuli. (12 Dec 1998) |
| inappropriate affect | An emotional tone or outward emotional reaction out of harmony with the idea, object, or thought accompanying it. (05 Mar 2000) |
| receptors, pituitary hormone-regulating hormone | Cell surface receptors that bind the hypothalamic hormones regulating pituitary cell differentiation, proliferation, and hormone synthesis and release, including the pituitary-releasing and release-inhibiting hormones. The pituitary hormone-regulating hormones are also released by cells other than hypothalamic neurons, and their receptors also occur on non-pituitary cells, especially brain neurons, where their role is less well understood. Receptors for dopamine, which is a prolactin release-inhibiting hormone as well as a common neurotransmitter, are not included here. (12 Dec 1998) |
| growth hormone 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) |
| growth hormone-regulating hormone | <endocrinology> Hypothalamic hormones that induce (somatoliberin) or inhibit (somatostatin) the release of growth hormone (somatotropin). (18 Nov 1997) |
| growth hormone-releasing hormone | <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) |
| hormones, hormone substitutes, and hormone antagonists | A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists. (12 Dec 1998) |
| follicle-stimulating hormone-releasing hormone | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| luteinizing hormone/follicle-stimulating hormone-releasing factor | gonadotrophin-releasing hormone |
| luteinizing hormone-releasing hormone | A hormone that controls sex hormones in men and women. Also called lhrh. (12 Dec 1998) |
| adipokinetic hormone | An anterior pituitary hormone that causes mobilization of fat from adipose tissue. Synonym: adipokinetic hormone. (05 Mar 2000) |
| adrenal androgen-stimulating hormone | A putative pituitary hormone that may be responsible for increased secretion of adrenal androgens at the time of puberty. (05 Mar 2000) |
| adrenocorticotrophic hormone | <endocrinology> A peptide hormone that is produced by the anterior pituitary gland. It stimulates the adrenal cortex to secrete glucocorticoid hormones, which help cells synthesise glucose, catabolize proteins, mobilizefree fatty acids and inhibit inflammation in allergic responses.
