chemical element, atomic number 79, atomic weight 196.967. (See Appendix 6.) Gold and many of its compounds are used in medicine, especially in treating rheumatoid arthritis. Gold salts are among the most toxic of therapeutic agents and must be given only under strict medical supervision. Toxic reactions may vary from mild to severe kidney or liver damage and blood dyscrasias.
gold 198 a radioisotope of gold having a half-life of 2.7 days, used as either a solid (seed) or a colloidal solution. It has been used for intracavitary or interstitial radiation therapy and has also been used, in colloidal form, as a scintiscanning agent. Symbol 198Au.
gold sodium thiomalate a gold preparation used as a disease-modifying antirheumatic drug in treatment of early active rheumatoid arthritis not controlled by nonsteroidal antiinflammatory drugs, rest, and physical therapy; administered intramuscularly.

gold (Au)

Etymology: AS, geolu, yellow
a yellowish soft metallic element that occurs naturally as a free metal and as the telluride AuAgTe4. Its atomic number is 79; its atomic mass is 196.97. Gold has been highly valued since antiquity and has been and is used for currency, for ornamentation, and as a dental restorative material. It is usually hardened by alloying it with small amounts of nickel or copper. It is highly resistive to oxidation but can be dissolved in aqua regia and aqueous potassium cyanide. Gold salts, in which gold is attached to sulfur, are often used in the treatment, or chrysotherapy, of patients with rheumatoid arthritis but cause serious toxicity in about 10% of patients and some toxicity in 25% to 50%. See also chrysotherapy.
