lyons gold
| gold alloy | An alloy whose principal ingredient is gold, usually contains copper or platinum and silver; used in dentistry for restorations requiring considerable strength. (05 Mar 2000) |
|---|---|
| gold alloys | Alloys that contain a high percentage of gold. They are used in restorative or prosthetic dentistry. (12 Dec 1998) |
| gold casting | A casting made of gold, usually formed to represent and replace lost tooth structure. (05 Mar 2000) |
| gold colloid | A purplish suspension of minute particles of metallic gold, made by reducing a solution of bromauric acid or other acid or salt of gold. It is used as a probe in immunochemistry. (12 Dec 1998) |
| gold colloid, radioactive | <chemical> A radioactive suspension of minute particles of metallic gold, made by exposure to neutrons. It is used in the pleural cavity to treat lung cancer. Pharmacological action: antineoplastic agent, radiopharmaceuticals. (12 Dec 1998) |
| 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) |
