| Nezelof type of thymic alymphoplasia | Synonym: cellular immunodeficiency with abnormal immunoglobulin synthesis. (05 Mar 2000) |
| thymic | <anatomy> Of or pertaining to the thymus gland. <medicine> Pertaining to, or derived from, thyme; as, thymic acid. Source: Websters Dictionary (01 Mar 1998) |
| thymic abscesses | Small cysts of the thymus containing polymorphonuclear leukocytes but lined by squamous epithelium; reported in congenital syphilis but also found in the absence of syphilis. Synonym: Dubois' disease, thymic abscesses. (05 Mar 2000) |
| thymic acid | Synonym: thymol. Origin: see thyme (05 Mar 2000) |
| thymic agenesis | The absence of the thymus, which may be associated with parathyroid agenesis in DiGeorge syndrome. (05 Mar 2000) |
| thymic alymphoplasia | Hypoplasia with absence of Hassall's corpuscles and deficiency of lymphocytes in the thymus and usually in lymph nodes, spleen, and gastrointestinal tract; there is peripheral lymphopenia and often hypogammaglobulinaemia and absence of plasma cells; presents in early infancy with respiratory infections and leads to death within a few months. See: immunodeficiency with hypoparathyroidism. (05 Mar 2000) |
| thymic aplasia | <disease, immunology> A lack of T lymphocytes, due to failure of the thymus to develop, resulting in very reduced cell-mediated immunity though serum immunoglobulin levels may be normal. See: DiGeorge syndrome. Origin: Gr. Plassein = to form (18 Nov 1997) |
| thymic arteries | <anatomy, artery> Small twigs supplying anterior mediastinal structures: mainly thymus and lymph nodes. Synonym: rami mediastinales arteriae thoracicae internae, rami thymici, anterior mediastinal arteries, arteriae thymicae, thymic arteries. (05 Mar 2000) |
| thymic branches of internal thoracic artery | <anatomy, artery> See: mediastinal branches of internal thoracic artery. (05 Mar 2000) |
| thymic corpuscle | Small spherical bodies of keratinised and usually squamous epithelial cells arranged in a concentric pattern around clusters of degenerating lymphocytes, eosinophils, and macrophages; found in the medulla of the lobules of the thymus. Synonym: Hassall's bodies, Hassall's concentric corpuscle, Virchow-Hassall bodies. (05 Mar 2000) |
| thymic factor, circulating | <chemical> A thymus-dependent nonapeptide found in normal blood. Stimulates the formation of e rosettes and is believed to be involved in T-cell differentiation. Chemical name: Thymulin (12 Dec 1998) |
| 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) |
| thymic hypoplasia | diGeorge syndrome |
| thymic lymphopoietic factor | A glycoprotein (MW about 12,000) that has been extracted from thymus; this thymus-produced hormone(s) confers immunological competence on thymus-dependent cells and induces lymphopoiesis. (05 Mar 2000) |
