| triiodothyronine uptake test | A test of thyroid function in which triiodothyronine (T3) is added to a patient's serum in vitro to measure the relative affinities of serum proteins and of an added competitive substance for T3; higher T3 uptakes are associated with hyperthyroidism. Synonym: T3 uptake test. (05 Mar 2000) |

| hormone, triiodothyronine | A hormone made by the thyroid gland. The thyroid gland uses iodine to make thyroid hormones. Triiodothyronine (t3) has three iodine molecules attached to its molecular structure. Iodine is found in seafood, bread, seaweed, and ordinary table salt. (12 Dec 1998) |
| triiodothyronine | <endocrinology, hormone> One of two main hormones produced by the thyroid gland. Free triiodothyronine is that not bound by thyroid binding globulin in the plasma and the levels are are high in hyperthyroidism, nephrotic syndrome and renal failure and low in acute hepatitis, hypothyroidism and pregnancy. Abbreviation: T3 (27 Sep 1997) |
| triiodothyronine, reverse | <chemical> 0-(4-hydroxy-3,5-diiodophenyl)-3-iodo-l-tyrosine. A metabolite of thyroxine formed by the peripheral degradation of thyroxine as a result of the tyrosyl or inner ring 5-deiodination. In systemic disease states or in neonates, levels of triiodothyronine are low and those of reverse triiodothyronine are elevated. Reverse t3 is therefore useful as a diagnostic aid and in the treatment of foetal and infantile hypothyroidism. Chemical name: L-Tyrosine, O-(4-hydroxy-3,5-diiodophenyl)-3-iodo- (12 Dec 1998) |
| triiodothyronine toxicosis | Hyperthyroidism resulting from excessive circulating 3,5,3'-triiodothyronine. Synonym: thyroid toxicosis. (05 Mar 2000) |
| 3,5,3'-triiodothyronine | A thyroid hormone normally synthesised in smaller quantities than thyroxine; present in blood and in thyroid gland and exerts the same biological effects as thyroxine but, on a molecular basis, is more potent and the onset of its effect is more rapid. (05 Mar 2000) |
| adrenergic uptake inhibitors | Drugs that block the transport of adrenergic transmitters into axon terminals or into storage vesicles within terminals. The tricyclic antidepressants (antidepressive agents, tricyclic) and amphetamines are among the therapeutically important drugs that may act via inhibition of adrenergic transport. Many of these drugs also block transport of serotonin. (12 Dec 1998) |
| Amine Precursor Uptake and Decarboxylation | <pharmacology, physiology> Paracrine cells of which argentaffin cells are an example. Usage of the term APUD is neither helpful nor memorable. Acronym: APUD (11 Nov 1997) |
| gallium uptake with normal chest film | <radiology> Pulmonary drug toxicity, tumour infiltration, sarcoidosis, pneumocystis carinii see: lung: gallium imaging (12 Dec 1998) |
| radioactive iodide uptake test | A test of thyroid function in which 131I-iodide is given orally; after 24 hours, the amount present in the thyroid gland is measured and compared with normal values. Synonym: radioactive iodide uptake test, RAI test. (05 Mar 2000) |
| serotonin uptake inhibitors | Compounds that specifically inhibit the reuptake of serotonin in the brain. This increases the serotonin concentration in the synaptic cleft which then activates serotonin receptors to a greater extent. These agents have been used in treatment of depression, panic disorder, obsessive-compulsive behaviour, and alcoholism, as analgesics, and to treat obesity and bulimia. Many of the adrenergic uptake inhibitors also inhibit serotonin uptake; they are not included here. (12 Dec 1998) |
| neurotransmitter uptake inhibitors | Drugs that inhibit the transport of neurotransmitters into axon terminals or into storage vesicles within terminals. For many transmitters, uptake determines the time course of transmitter action so inhibiting uptake prolongs the activity of the transmitter. Blocking uptake may also deplete available transmitter stores. Many clinically important drugs are uptake inhibitors although the indirect reactions of the brain rather than the acute block of uptake itself is often responsible for the therapeutic effects. (12 Dec 1998) |
| dopamine uptake inhibitors | Drugs that block the transport of dopamine into axon terminals or into storage vesicles within terminals. most of the adrenergic uptake inhibitors also inhibit dopamine uptake. (12 Dec 1998) |
| iodine uptake test | A test of thyroid function in which 131I-iodide is given orally; after 24 hours, the amount present in the thyroid gland is measured and compared with normal values. Synonym: radioactive iodide uptake test, RAI test. (05 Mar 2000) |
| T3 uptake test | A test of thyroid function in which triiodothyronine (T3) is added to a patient's serum in vitro to measure the relative affinities of serum proteins and of an added competitive substance for T3; higher T3 uptakes are associated with hyperthyroidism. Synonym: T3 uptake test. (05 Mar 2000) |
