| lyotropic series | <chemistry> A listing of anions and cations in order of their effect on protein solubility (tendency to cause salting out). Essentially a competition between the protein and the ion for water molecules for hydration. (20 Mar 1998) |
|---|---|
| acute lymphocytic leukaemia | <radiology> 95% of cases of leukaemia in children, bone changes in 50-70% of kids (vs. 10% in adults); seen as early as 1 month after onset of symptoms, wrists and knees most commonly affected, bony defects: metaphyseal radiolucent bands! (similar findings in scurvy, JRA, syphilis), osteolytic lesions, periosteal reaction, osteosclerosis (12 Dec 1998) |
| acute non-lymphocytic leukaemia | <haematology> A form of leukaemia which is characterised by the proliferation of immature bone marrow precursor cells in the marrow and immature white blood cells (granulocytes) in the bloodstream. Occurs primarily in adults and in infants under 1 year of age. Complications include abnormal bleeding and susceptibility to infections. Symptoms include fatigue, weight loss, fevers, weakness, pallor, bone pains, bleeding gums, nosebleeds, easy bruising, enlarged lymph nodes and joint pains. Trisomy-8 is the most common cytogenetic abnormality observed, followed by monosomy-7 and monosomy-5. Approximately 8% of cases show trisomy-8, mostly in AML (M1), AM (M4) and acute monocytic leukaemia (M5). Many pre-leukaemic conditions, acute non-lymphocytic leukaemia and secondary leukemia show monosomy-7 or deletion of the long arm of chromosome 7. Treatment includes chemotherapy and/or bone marrow transplant. Acronym: ANLL Incidence: 2.5 cases per 100,000 (all ages). Origin: Gr. Haima = blood (07 Apr 1998) |
| chronic lymphocytic leukaemia | <haematology> A slowly progressing form of leukaemia, characterised by an increased number of the type of white blood cell known as lymphocytes. With about 3, 500 new cases occurring each year in the UK, it is the most common form of leukaemia and occurs predominantly in late middle age onwards. It has variable symptoms and course, but may be diagnosed by chance before the patient develops any clinical symptoms of disease. Acronym: CLL Origin: Gr. Haima = blood (12 Jan 1998) |
| chronic lymphocytic thyroiditis | <endocrinology> Inflammation of the thyroid gland without the formation of pus. Noninfectious nonbacterial thyroid inflammation. (27 Sep 1997) |
| well-differentiated lymphocytic lymphoma | <tumour> Essentially the same disease as chronic lymphocytic leukaemia, except that lymphocytes are not increased in the peripheral blood; lymph nodes are enlarged and other lymphoid tissue or bone marrow is infiltrated by small lymphocytes. Synonym: small lymphocytic lymphoma. (05 Mar 2000) |
| poorly differentiated lymphocytic lymphoma | <tumour> A B-cell lymphoma with nodular or diffuse lymph node or bone marrow involvement by large lymphoid cells. Synonym: follicular predominantly small cleaved cell lymphoma, nodular histiocytic lymphoma. (05 Mar 2000) |
| small lymphocytic lymphoma | <tumour> Essentially the same disease as chronic lymphocytic leukaemia, except that lymphocytes are not increased in the peripheral blood; lymph nodes are enlarged and other lymphoid tissue or bone marrow is infiltrated by small lymphocytes. Synonym: small lymphocytic lymphoma. (05 Mar 2000) |
| focal lymphocytic thyroiditis | Focal infiltration of the thyroid by lymphocytes and plasma cells. See: Hashimoto's thyroiditis. (05 Mar 2000) |
| leukaemia, lymphocytic | Leukaemia associated with hyperplasia and overactivity of the lymphoid tissue. There are increased numbers of circulating malignant lymphocytes and lymphoblasts. (12 Dec 1998) |
| lymphocytic | <haematology> Pertaining to, characterised by or of the nature of lymphocytes. (18 Nov 1997) |
| lymphocytic adenohypophysitis | A diffuse lymphocytic infiltration of the adenohypophysis, often related to pregnancy; probably a disturbance in the immune system. (05 Mar 2000) |
| lymphocytic choriomeningitis | A form of viral meningitis caused by the lymphocytic choriomeningitis virus. In humans it may be inapparent or present with symptoms of a flu-like disease, aseptic meningitis, encephalitis, or myelitis. (12 Dec 1998) |
| lymphocytic choriomeningitis virus | The type species of arenavirus, part of the lcm-lassa complex viruses, producing an inapparent infection in house and laboratory mice. In humans, infection with lcmv can be inapparent, or can present with an influenza-like illness, a benign aseptic meningitis, or a severe meningoencephalomyelitis. The virus can also infect monkeys, dogs, field mice, guinea pigs, and hamsters, the latter an epidemiologically important host. (12 Dec 1998) |
| lymphocytic interstitial pneumonia | 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. In children. Sometimes seen as an autoimmune disorder. Synonym: lymphocytic interstitial pneumonia, lymphoid interstitial pneumonia. (05 Mar 2000) |
