| 8-CPT | 8-cyclopentyl theophylline |
| theophylline | <drug> Inhibits cAMP phosphodiesterase and is often used in conjunction with exogenous dibutyryl cyclic AMP to raise cellular cAMP levels. Other, less potent, methylxanthines are caffeine, theobromine and aminophylline. (18 Nov 1997) |
|---|---|
| theophylline aminoisobutanol | <drug> A diuretic and bronchodilator. Synonym: theophylline aminoisobutanol. (05 Mar 2000) |
| theophylline calcium salicylate | A mixture of calcium theophylline and sodium salicylate in molecular proportion; has the same actions and uses as theophylline. (05 Mar 2000) |
| theophylline ethanolamine | Theophylline monoethanolamine, with the same actions and uses as theophylline. (05 Mar 2000) |
| theophylline ethylenediamine | <drug> An inhibitor of cAMP phosphodiesterase. (18 Nov 1997) |
| theophylline isopropanolamine | Has the same actions and uses as aminophylline, but a more rapid onset and a longer duration of action. (05 Mar 2000) |
| theophylline oxidase | <enzyme> Catalyses the oxidation of theophylline to 1,3-dimethyluric acid in the presence of ferricytochrome c Registry number: EC 1.5.99.- (26 Jun 1999) |
| theophylline sodium acetate | A mixture of theophylline sodium and sodium acetate, with 60% of theophylline; has the same uses as theophylline. (05 Mar 2000) |
| theophylline sodium glycinate | Equilibrium mixture containing theophylline sodium and glycine in approximately molecular proportions, buffered with an additional mole of glycine; similar in action and uses to aminophylline but more stable in air, and less irritating to the gastric mucosa. (05 Mar 2000) |
| amino acid reagent | A reagent used in the identification and quantification of amino acids. (05 Mar 2000) |
| Benedict-Hopkins-Cole reagent | <chemistry> Magnesium glyoxalate, made from a mixture of oxalic acid and magnesium, used for testing proteins for the presence of tryptophan. (12 Aug 2000) |
| biuret reagent | An alkaline solution of copper sulfate. (05 Mar 2000) |
| Mandelin's reagent | A solution of ammonium vanadate in sulfuric acid, used in colour tests for alkaloids. (05 Mar 2000) |
| reagent | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour. Acronym: PAS (18 Nov 1997) |
| reagent kits, diagnostic | Commercially prepared reagent sets, with accessory devices, containing all of the major components and literature necessary to perform one or more designated diagnostic tests or procedures. They may be for laboratory or personal use. (12 Dec 1998) |
