| thrombolytic therapy | The use of thrombolytic agents to dissolve blood clots to re-establish blood flow through an occluded vessel. Examples of thrombolytic agents include: urokinase, streptokinase and tissue plasminogen activator (TPA). These agents may be introduced into a vein or selectively into a diseased (blocked) artery using a catheter. (27 Sep 1997) |

| thymic hormone | <endocrinology> One of the hormones produced by the thymus that are believed to play a role in the maturation of T-lymphocytes and overall modulation of the immune system. Versions of several of them are under study as anti-HIV therapies-thymopentin and thymosin-a1 in particular. (09 Oct 1997) |
| ectopic hormone | A hormone formed by tissue outside the normal endocrine site of production; e.g., adrenocorticotropic hormone produced by a bronchogenic carcinoma. Synonym: inappropriate hormone. (05 Mar 2000) |
| thyroid hormone | <endocrinology> Thyroxine and tri iodothyronine are hormones secreted by the thyroid gland in vertebrates. These iodinated aromatic amino acid compounds influence growth and metabolism and, in amphibia, metamorphosis. The hormone calcitonin which has hypocalcaemic effects is also of thyroid origin but is not usually classed with thyroxine and tri iodothyronine as a thyroid hormone. (18 Nov 1997) |
| thyroid hormone aminotransferase | <enzyme> Chemical name: 3,5-dinitrotyrosine aminotransferase Registry number: EC 2.6.1.26 Synonym: triiodothyrone aminotransferase, triiodothyronine aminotransferase (26 Jun 1999) |
| thyroid hormone resistance syndrome | <syndrome> An inherited syndrome of peripheral resistance to thyroid hormones, transmitted as an autosomal recessive trait, characterised by increased serum concentrations of thyroxine and triiodothyronine, increased thyroid hormone binding ratio, and normal to slightly increased thyroid-stimulating hormone and its response to thyrotropin-releasing hormone. The affected persons are euthyroid to slightly hypothyroid. The absence of hypermetabolism and the presence of possible hypothyroidism indicate the existence of partial resistance to the peripheral action of thyroid hormone. (12 Dec 1998) |
| thyroid releasing hormone | <endocrinology> Thyroid releasing hormone (TRH) is a byproduct of the hypothalamus and serves to stimulate the pituitary gland to produce thyroid stimulating hormone (TSH). TRH is produced by the hypothalamus when thyroid hormone (T3 and T4) blood levels are low. (27 Sep 1997) |
| thyroid stimulating hormone | <endocrinology> Polypeptide hormone (28 kD), secreted by the anterior pituitary gland, that activates cyclic AMP production in thyroid cells leading to production and release of the thyroid hormones (T4 and T3). T4 and T3 blood levels feedback on the pituitary gland and decrease thyroid stimulating hormone production when T3 and T4 levels are high. (27 Sep 1997) |

| thyroid-stimulating hormone stimulation test | TSH stimulating test, a test that measures the uptake of 131I in the thyroid gland before and after administration of thyroid-stimulating hormone; useful in distinguishing primary hyperthyroidism (increased TSH serum concentration) from secondary or tertiary hyperthyroidism (low TSH serum concentrations).

| thyroid therapy | The treatment of hypothyroidism. (05 Mar 2000) |
| thyrotrophic releasing hormone | <endocrinology> Tripeptide (pyroGlu His Pro NH2) that releases thyrotrophin from the anterior pituitary by stimulating adenyl cyclase. May also have neurotransmitter and paracrine functions. (18 Nov 1997) |
| thyrotropic hormone | thyroid stimulating hormone |
| thyrotropin-releasing hormone | <protein> See thyrotrophic releasing hormone. (18 Nov 1997) |
