|---|---|
| SHG | synthetic human gastrin |
| prostaglandins f, synthetic | Analogs or derivatives of prostaglandins f that do not occur naturally in the body. They do not include the product of the chemical synthesis of hormonal pgf. (12 Dec 1998) |
|---|---|
| prostaglandins, synthetic | Compounds obtained by chemical synthesis that are analogs or derivatives of naturally occurring prostaglandins and that have similar activity. (12 Dec 1998) |
| synthetic | Relating to or made by synthesis. (05 Mar 2000) |
| synthetic chemistry | The formation or building up of complex compounds by uniting the more simple ones. (05 Mar 2000) |
| synthetic dyes | Organic dye compounds originally derived from coal-tar derivatives; presently produced by synthesis from benzene and its derivatives; examples include eosin, methylene blue, and fluorescein. (05 Mar 2000) |
| oestrogens, synthetic | Compounds obtained by chemical synthesis which possess oestrogenic activity, but differ in structure from naturally occurring oestrogens. (12 Dec 1998) |
| adrenocortical hormones | Hormone's secreted by the human adrenal cortex; e.g., cortisol, aldosterone, corticosterone. (05 Mar 2000) |
| adrenomedullary hormones | Hormones produced by the adrenal medulla, particularly the catecholamines epinephrine and norepinephrine. (05 Mar 2000) |
| pancreatic hormones | Peptide hormones secreted into the blood by cells in the islets of langerhans of the pancreas. The alpha cells secrete glucagon; the beta cells secrete insulin; the delta cells secrete somatostatin; and the pp cells secrete pancreatic polypeptide. (12 Dec 1998) |
| gastrointestinal hormones | Hormones that originate in and regulate motor and secretory activity of the digestive organs. (12 Dec 1998) |
| parathyroid hormones | Polypeptide hormones (84 amino acid residues) secreted by the parathyroid glands, which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts, indirectly promote increased intestinal absorption of calcium, and promote renal tubular reabsorption of calcium and increased renal excretion of phosphates. It is a major regulator of bone metabolism. Secretion of parathyroid hormone increases when the level of calcium in the extracellular fluid is low. Its action is opposed by calcitonin. (12 Dec 1998) |
| vertebrate hormones | Hormones synthesised in vertebrates. (05 Mar 2000) |
| glycoprotein hormones, alpha subunit | A non-covalently bound subunit of the glycoprotein hormones tsh, fsh, lh, and hcg which originates in the anterior pituitary gland and placenta. This subunit is virtually identical in structure and indistinguishable by radioimmunoassay in all of the above glycoproteins. It is present in both men and women, but is elevated in postmenopausal women and in patients with hypothyroidism, uraemia and malignant tumours. The alpha subunit may be involved directly in recognition of certain receptors. (12 Dec 1998) |
| gonadal hormones | Hormones having oestrogenic (female sex hormones) or androgenic (male sex hormones) activity. (12 Dec 1998) |
| pituitary hormone release inhibiting hormones | Polypeptide hormones produced in the hypothalamus which inhibit the release of pituitary hormones. (12 Dec 1998) |
