| 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) |
|---|
| aplasia | <embryology> A lack of development of an organ or tissue or of the cellular products from an organ or tissue. Compare: hypoplasia. Origin: Gr. Plassein = to form (18 Nov 1997) |

| aplasia cutis congenita | Congenital absence or deficiency of a localised area of skin, with the base of the defect covered by a thin translucent membrane; most often a single area near the vertex of the scalp, but may occur in other areas; underlying structures may also be affected; autosomal inheritance, either dominant or recessive. (05 Mar 2000) |
| radial aplasia-thrombocytopenia syndrome | <syndrome> Aplasia (absence) of the radius (the long bone on the thumb-side of the forearm) and thrombocytopenia (low blood platelets) are key features characterizing this syndrome. There is phocomelia (flipper-limb) with the thumbs always present. The fibula (the smaller bone in the lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the child affected with the disease. Alternative names include thrombocytopenia-absent radius syndrome, tar syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
| germinal aplasia | A disorder in which the seminiferous tubules exhibit an abnormal cytoarchitecture and extensive hyalinization; the testes are small, and few spermatozoa are formed; the body habitus may be eunuchoid, and gynaecomastia may be present; urinary gonadotropin output is usually high, and the incidence of mental deficiency and illness increased; sex chromatin may be male or female, and androgen secretion ranges from subnormal to normal. It is a constant feature of (and is often used synonymously with) Klinefelter's syndrome. Synonym: germinal aplasia. (05 Mar 2000) |
| red-cell aplasia, pure | Suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production. (12 Dec 1998) |
| gonadal aplasia | Congenital absence of essentially all gonadal tissue; the external genitalia and genital ducts are female, but if interstitial cells of Leydig are present, the external genitalia are commonly ambiguous and the genital ducts are female. See: gonadal dysgenesis. Compare: Klinefelter's syndrome, Turner's syndrome. Synonym: gonadal agenesis. (05 Mar 2000) |
| congenital aplasia of thymus | diGeorge syndrome |
| pure red cell aplasia | A transitory arrest of red blood cell production which may occur in the course of a haemolytic anaemia, often preceded by infection, or as a complication of certain drugs; if the arrest persists anaemia may result. See: congenital hypoplastic anaemia. (05 Mar 2000) |
| syndrome, radial aplasia-thrombocytopenia | See syndrome, tar. (12 Dec 1998) |
| mouse thymic virus | An unclassified ether-sensitive virus, 75 to 100 nm in diameter, that causes necrosis of the thymus in young mice. (05 Mar 2000) |
| 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) |
