| Naegeli type of monocytic leukaemia | A variant of granulocytic leukaemia with monocytosis in the peripheral blood. Synonym: Naegeli type of monocytic leukaemia. (05 Mar 2000) |
| acute monocytic leukaemia | <haematology> The most common translocation in this disorder of poorly differentiated monocytic cells involves chromosome region 11q in a large percentage of cases. The translocation involves a cellular oncogene, c-ets which is mapped to the 11q23-24 region. The most common translocations reported are t(6;11), t(9;11), t(11;17) and t(11;19), of which t(9;11) (p21-22;q23) is by far the most frequently detected and implicated in acute myeloid leukaemia. The cells express CD14 surface antigen, which is diagnostic of monocytic cells. Acronym: AML Classification: FAB M5 (07 Apr 1998) |
| monocytic angina | An obsolete term for infectious mononucleosis. (05 Mar 2000) |
| monocytic leukaemia | Cancer of the blood due to proliferation of cells of the monocyte series. Origin: Gr. Haima = blood (13 Nov 1997) |
| monocytic leukemoid reaction | Leukocytosis of varying degree, e.g., 30,000 to 40,000 per cu mm, with adult monocytes and immature forms amounting to 30% (or more) of the total number of white blood cells in the circulating blood; may be observed in association with tuberculosis, especially the first infection, miliary type. (05 Mar 2000) |
| monocytic leukocytosis | An abnormal increase in the number of monocytes in the circulating blood. Synonym: monocytic leukocytosis. (05 Mar 2000) |
| monocytic leukopenia | Diminution in the number of monocytes in the circulating blood. Synonym: monocytic leukopenia, monopenia. Origin: mono-+ G. Kytos, cell, + penia, poverty (05 Mar 2000) |
| equine monocytic ehrlichiosis | <veterinary> A febrile disease of horses in North America caused by Ehrlichia risticii and characterised by anorexia, leukopenia, and occasional diarrhoea. Synonym: Potomac horse fever. (05 Mar 2000) |
| acrocephalosyndactyly type 1 | <paediatrics> An inherited disease (autosomal dominant) or a spontaneously occurring disease characterised by a peaked head and unusual facial appearance, due to the premature closure of the cranial sutures. A skull X-ray can confirm the diagnosis and treatment is surgical. Inheritance: autosomal dominant. (27 Sep 1997) |
| Alzheimer type I astrocyte | Enlarged frequently multinucleated astrocytes, seen in progressive multifocal leukoencephalopathy. (05 Mar 2000) |
| Alzheimer type II astrocyte | Enlarged astrocytes with vesicular nuclei and one or more small basophilic nucleoli, seen in hepatocerebral disease and Wilson's disease. (05 Mar 2000) |
| American Type Culture Collection | <cell culture> A key resource for cultured cells, located in Rockville, USA. (12 Dec 1998) |
| Antoni type A neurilemoma | <tumour> Relatively solid or compact arrangement of neoplastic tissue that consists of Schwann cells arranged in twisting bundles and associated with delicate reticulin fibres; the nuclei of the Schwann cells are frequently grouped in parallel rows (so-called palisades), and the nuclei and fibres sometimes form exaggerated tactile corpuscles, called Verocay bodies. (05 Mar 2000) |
| Antoni type B neurilemoma | <tumour> Relatively soft or loose arrangement of neoplastic tissue that consists of Schwann cells in a haphazard or nondescript type of arrangement among reticulin fibres and tiny cystlike foci; fat-laden macrophages may be observed in some of the larger neoplasms.
