| leukaemia p388 | An experimental lymphocytic leukaemia originally induced in dba/2 mice by painting with methylcholanthrene. (12 Dec 1998) |
|---|---|
| leukaemia, smoldering | A condition in which the bone marrow does not function normally. It does not produce enough blood cells. This condition may progress and become acute leukaemia. Smoldering leukaemia also is called myelodysplastic syndrome or preleukaemia. (12 Dec 1998) |
| leukaemia virus, bovine | The type species of HTLV-blv viruses that causes a form of bovine lymphosarcoma (enzootic bovine leukosis) or persistent lymphocytosis. (12 Dec 1998) |
| leukaemia viruses, murine | Species of mammalian type c retroviruses (retroviruses type c, mammalian) producing leukaemia in mice. It is commonly induced by injecting filtrates of propagable tumours into newborn mice. The gross strain (gross virus) occurs spontaneously in inbred mice, but none of the other strains occurs naturally. (12 Dec 1998) |
| leukaemia virus, feline | A species of mammalian type c retrovirus (retroviruses type c, mammalian) causing leukaemia, lymphosarcoma, immune deficiency, or other degenerative diseases in cats. Several cellular oncogenes confer on felv the ability to induce sarcomas (see also sarcoma virus, feline). (12 Dec 1998) |
| leukaemia virus, gibbon ape | A species of mammalian type c retrovirus (retroviruses type c, mammalian) causing leukaemia in the gibbon ape. Natural transmission is by contact. (12 Dec 1998) |
| leukaemic leukaemia | A redundant term sometimes used to emphasize the occurrence of abundant numbers of leukaemic cells in the circulating blood; this classic form of leukaemia is usually termed simply leukaemia. (05 Mar 2000) |
| leukopenic leukaemia | A form of lymphocytic, granulocytic, or monocytic leukaemia in which the total number of white blood cells in the circulating blood is in the normal range, or may be diminished to various levels that are significantly less than normal. (05 Mar 2000) |
| lymphatic 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) |
| lymphoblastic leukaemia | Acute lymphocytic leukaemia in which the abnormal cells are chiefly (or almost totally) blast forms of the lymphocytic series, or in which unusually large numbers of the immature forms occur in association with adult lymphocytes. (05 Mar 2000) |
| 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) |

| abdomen, acute | Clinical syndrome characterised by abdominal pain of great severity associated with other symptoms and signs, usually those of acute peritonitis, which might well be the result of a ruptured abdominal viscus or a similar abdominal catastrophe requiring urgent surgical operation. (12 Dec 1998) |
| acute | 1. Sharp, poignant. 2. Having a short and relatively severe course. Origin: L. Acutus = sharp (18 Nov 1997) |
| acute abdomen | Any serious acute intra-abdominal condition (such as appendicitis) attended by pain, tenderness, and muscular rigidity, and for which emergency surgery must be considered. Synonym: surgical abdomen. (05 Mar 2000) |
