| gold compound | <pharmacology> A group of medications which act to suppress inflammation in synovial tissue. Examples include gold sodium thiomalate, auranofin and aurothioglucose. These medications are indicated in the treatment of rheumatoid arthritis, psoriatic arthritis, Felty's syndrome and juvenile rheumatoid arthritis. (27 Sep 1997) |

| gold compounds | Inorganic compounds that contain gold as an integral part of the molecule. (12 Dec 1998) |
| gold equivalent | A unit of power of the protective colloids; the number of milligrams of protective colloid just sufficient to prevent the precipitation of 10 ml of a 0.0053 to 0.0058% gold solution by the action of 1 ml of a 10% sodium chloride solution. Synonym: gold number. (05 Mar 2000) |
| gold foil | Pure gold rolled into extremely thin sheets; used in the restoration of carious or fractured teeth. See: cohesive gold, noncohesive gold. (05 Mar 2000) |
| gold inlay | A gold restoration fabricated by casting in a mold made from a wax pattern; the restoration is sealed in the prepared cavity with dental cement. (05 Mar 2000) |
| gold isotopes | Stable gold atoms that have the same atomic number as the element gold, but differ in atomic weight. Au-197 is a stable isotope. (12 Dec 1998) |
| gold-myokymia syndrome | <syndrome> The symptom complex of widespread myokymia, muscle aching, and autonomic disturbances (excess sweating; orthostatic hypotension) that can result from gold therapy. (05 Mar 2000) |
| gold number | A unit of power of the protective colloids; the number of milligrams of protective colloid just sufficient to prevent the precipitation of 10 ml of a 0.0053 to 0.0058% gold solution by the action of 1 ml of a 10% sodium chloride solution. Synonym: gold number. (05 Mar 2000) |
| gold radioisotopes | Unstable isotopes of gold that decay or disintegrate emitting radiation. Au 185-196, 198-201, and 203 are radioactive gold isotopes. (12 Dec 1998) |
| gold sodium thiomalate | <chemical> A variable mixture of the mono- and disodium salts of gold thiomalic acid used mainly for its anti-inflammatory action in the treatment of rheumatoid arthritis. It is most effective in active progressive rheumatoid arthritis and of little or no value in the presence of extensive deformities or in the treatment of other forms of arthritis. Pharmacological action: antirheumatic agents, gold. Chemical name: Butanedioic acid, mercapto-, monogold(1+) sodium salt (12 Dec 1998) |
| gold sodium thiosulfate | <chemical> An antirheumatic agent with the same actions and uses as gold sodium thiomalate. Pharmacological action: antirheumatic agents, gold. Chemical name: Aurate(3-), bis(monothiosulfato(2-)-O,S)-, trisodium, (T-4)- (12 Dec 1998) |
| gold sol test | An obsolete, non-specific test for altered proteins in spinal fluid. As originally used by Lange in 1912, the test was thought to be specific for neurosyphilis; however, this proved to be incorrect. Dilutions of spinal fluid are made in saline and to these a colloidal gold solution is added; if altered proteins are present, there is a colour change or precipitate formed. at present, its chief use is to demonstrate cerebrospinal fluid protein abnormalities in multiple sclerosis. Synonym: gold sol test, Zsigmondy's test. (05 Mar 2000) |
| gold standard | Term used to describe a method or procedure that is widely recognised as the best available. Origin: jargon (05 Mar 2000) |
| gold thioglucose | <chemical> (1-thio-d-glucopyranosato)gold. A thioglucose derivative used as an antirheumatic and experimentally to produce obesity in animals. Pharmacological action: antirheumatic agents, gold. Chemical name: Gold, (1-thio-D-glucopyranosato-O2,S1)- (12 Dec 1998) |
| cohesive gold | Nearly pure gold so treated as to be free of adsorbed surface gases and impurities so that it will weld under pressure at room temperature; in dentistry, used as a restorative material placed directly into a prepared cavity and welded by pressure. (05 Mar 2000) |
