| lymphocytic interstitial pneumonitis | A rare disease characterised by interstitial accumulation of lymphocytes in the lungs and late fibrosis; usually a result of a lymphoma, occasionally seen in AIDS, especially.

| lymphocytic leukaemia | <haematology, oncology> An acute form of childhood leukaemia characterised by the development of abnormal cellsdevelop in the bone marrow and lymphoblasts are found in blood-formingtissues. A type of chronic leukaemia found most often in the elderly, it is characterised by the presence of mature lymphocytes in the blood. Origin: Gr. Haima = blood (13 Nov 1997) |
| lymphocytic leukemoid reaction | Leukocytosis of varying degree, with adult lymphocytes and immature forms amounting to 40% (or more) of the total number of white blood cells in the circulating blood; may be observed in association with pertussis, infectious mononucleosis, gonorrhoea, chickenpox, and sarcoidosis. (05 Mar 2000) |
| lymphocytic leukocytosis | A condition in which the blood contains an unusually high number of normal lymphocytes. (09 Oct 1997) |
| lymphocytic leukopenia | Reduction in the number of lymphocytes. (12 Dec 1998) |
| lymphocytic lymphoma | <oncology, tumour> A cancer of lymphatic tissues, the tumour cells are mostly abnormal lymphocytes. (13 Nov 1997) |
| lymphocytic thyroiditis | <endocrinology> Inflammation of the thyroid gland without the formation of pus. Noninfectious nonbacterial thyroid inflammation. (27 Sep 1997) |
| lymphoma, small lymphocytic | A low-grade malignant lymphoma that may, in some cases, be considered histologically identical to chronic lymphocytic leukaemia (cll; leukaemia, lymphocytic, chronic). It is diffuse in pattern, representing the neoplastic proliferation of well-differentiated B-lymphocytes. In patients with immunoglobulin gammopathies, the lymphocytes may exhibit plasmacytoid characteristics. (12 Dec 1998) |
| bovine virus diarrhoea virus | A virus of the genus Pestivirus, in the family Togaviridae, causing bovine virus diarrhoea; New York, Oregon, and Indiana strains of the virus are recognised. Synonym: mucosal disease virus. (05 Mar 2000) |
| abelson leukaemia virus | A defective murine leukaemia virus capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukaemia after superinfection with friend, moloney, or rauscher virus. (12 Dec 1998) |
| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (05 Mar 2000) |
| adeno-associated virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| adenoidal-pharyngeal-conjunctival virus | <virology> An icosahedral (20-sided) virus that contains DNA, there are over 40 different adenovirus varieties, some of which cause the common cold. (10 May 1997) |
| adenosatellite virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| african horse sickness virus | A species of orbivirus that causes disease in horses, mules, and donkeys. (12 Dec 1998) |
