| dipyridamole-thallium imaging | <radiology> Myocardial perfusion imaging for patients who cannot exercise, dipyridamole, potent coronary vasodilator, dose: 300 mg IV, side effects relieved by aminophyllin, thallium given when: symptomatic, HR increased 10 bpm, diastolic BP decreased 10 mm Hg, 45 min after PO dose (12 Dec 1998) |

| thallium | <chemistry> A rare metallic element of the aluminium group found in some minerals, as certain pyrites, and also in the lead-chamber deposit in the manufacture of sulphuric acid. It is isolated as a heavy, soft, bluish white metal, easily oxidized in moist air, but preserved by keeping under water. Symbol Tl. Atomic weight 203.7. Origin: NL, fr. Gr. Young or green shoot or branch, twig. So called from a characteristic bright green line in its spectrum. Source: Websters Dictionary (01 Mar 1998) |
| thallium 201 | <radiology> Tl-201, half-life: 73 hours (ca. 3 days), radiation: 68-80 keV photons (mercury X-rays), 135 and 167 keV gamma rays, cyclotron produced see: myocardial perfusion imaging (12 Dec 1998) |
| thallium heart scan | <cardiology, investigation, radiology> A test which involves the introduction of a radioactive tracer into the bloodstream. The radioactive tracer is then measured with a special camera and a determination of coronary artery blood flow can be made. (27 Sep 1997) |
| thallium poisoning | A condition characterised by vomiting, diarrhoea, leg pains, and severe sensorimotor polyneuropathy; about three weeks after poisoning, temporary extensive loss of hair typically occurs; usually occurs after accidental ingestion of a rodenticide. (05 Mar 2000) |
| thallium radioisotopes | Unstable isotopes of thallium that decay or disintegrate emitting radiation. Tl atoms with atomic weights 198-202, 204, and 206-210 are thallium radioisotopes. (12 Dec 1998) |
| thallium stress test | <cardiology, investigation> This test is used to assess coronary blood flow before and after a period of strenuous exercise. Thallium testing involves the introduction of a radioactive tracer into the bloodstream. The radioactive tracer is then measured with a special camera and a determination of coronary artery blood flow can be made. (27 Sep 1997) |
| acid sulfate | A salt containing HSO4-. Synonym: acid sulfate. (05 Mar 2000) |
| active sulfate | 3'-phosphoadenosine 5'-phosphosulfate;an intermediate in the formation of urinary ethereal sulfates, notable for containing a "high energy" sulfate bond; the 3'-OH of adenosine is replaced by -OPO3H2, the 5'-OH by -OP(O2H)-OSO3H. Synonym: active sulfate. Acronym: PAPS (05 Mar 2000) |
| adenine sulfate | Adenine conjugated with sulfuric acid; used to stimulate leukocyte production in agranulocytosis. (05 Mar 2000) |
| adenylyl sulfate-ammonia adenylyltransferase | <enzyme> Forms adenosine 5'-phosphoramidate Registry number: EC 2.7.7.- Synonym: adenylyl sulphate-ammonia adenylyltransferase, as-aat (26 Jun 1999) |

| aluminum sulfate octadecahydrate | Astringent detergent for skin ulcers. Synonym: cake alum. (05 Mar 2000) |
| amikacin sulfate | An aminoglycoside antibiotic agent with antimicrobial activity similar to that of kanamycin; also effective against Pseudomonas aeruginosa. (05 Mar 2000) |
