Lympho: From 1 Different Sources
combining form denoting lymph or the lymphatic system.
A neoplasia of the lymph tissue, such as Hodgkin’s Disease. Although it is frequently useful to stimulate immunity when a person is undergoing chemotherapy for cancer, since the resultant immunosuppression is a major side effect of the treatment, in lymphatic cancer this the POINT of the therapy...let it be.... lymphoma
Swelling of a part or organ due to obstruction to the LYMPH vessels draining it.... lymphoedema
A traditional term for non-Hodgkin’s lymphoma (see LYMPHOMA).... lymphosarcoma
A variety of white blood cell produced in the LYMPHOID TISSUE and lymphatic glands (see LYMPHATICS; GLAND) of the body. It contains a simple, rounded nucleus surrounded by protoplasm generally described as non-granular. Two varieties of lymphocyte are described, small and large, and together they form over 20 per cent of the white cells of the blood. They play an important part in the production of ANTIBODIES, and in the rejection of transplanted organs such as the heart (see TRANSPLANTATION). This they do in two di?erent ways: what are known as B-lymphocytes produce antibodies, while T-lymphocytes attack and destroy antigens (see ANTIGEN) directly. The latter are known as T-lymphocytes because they are produced by the THYMUS GLAND. Their numbers are increased in TUBERCULOSIS and certain other diseases. Such an increase is known as LYMPHOCYTOSIS.... lymphocyte
(LGV) A tropical sexually transmitted disease caused by Chlamydia trachomatis serotypes L1, L2 and L3.... lymphogranuloma venereum
Lymphoid tumour associated with Epstein-Barr (EB) virus. Especially common in malaria endemic areas, such as Africa and Papua New Guinea. May be associated with the immunosuppressive effects of the malaria infection.... burkitt’s lymphoma
An increase in the number of lymphocytes in the blood (see LYMPHOCYTE) – for example, in response to viral infection or in chronic lymphocytic LEUKAEMIA.... lymphocytosis
Tissue involved in the formation of LYMPH, lymphocytes (see LYMPHOCYTE), and ANTIBODIES. It consists of the LYMPH NODES, THYMUS GLAND, TONSILS and SPLEEN.... lymphoid tissue
See LYMPHOCYTE.... t-lymphocyte
A cancer of lymph tissues that is characterized by tumours within the jaw and/or abdomen. It is confined almost exclusively to children living in low-lying, moist, tropical regions of Africa and New Guinea. Anticancer drugs or radiotherapy give complete or partial cure in about 80 per cent of cases. (See also lymphoma.)... burkitt’s lymphoma
A type of white blood cell that circulates through the body and is able to detect the presence of the foreign agents. Once exposed to an antigen on the agent, these cells differentiate into plasma cells to produce antibody.... b-lymphocyte (or b-cell)
A venereal disease in which the chief characteristic is enlargement of glands in the groin – the infecting agent being a virus.... lymphogranuloma inguinale
Lymphokines are polypeptides that are produced by lymphocytes (see LYMPHOCYTE) as part of their immune response to an ANTIGEN; their function is to communicate with other cells of the immune system (see IMMUNITY). Some lymphokines stimulate B-cells to di?erentiate into antibody-producing plasma cells; others stimulate T-lymphocytes to proliferate; other lymphokines become interferons (see INTERFERON).... lymphokines
See LYMPHOMA.... malignant lymphoma
See LYMPHOMA.... non-hodgkin’s lymphoma
See LYMPHOMA.... t-cell lymphoma
White blood cells that have matured in the thymus gland. There are at least two kinds of T-lymphocytes - helpers and suppressors. In AIDS, the number of helper cells is decreased.... t-lymphocytes (or t-cells)
Treatment: same as for Gonorrhoea. ... lymphogranuloma venereum (lgv)
n. see lymphocyte.... b lymphocyte
a group of lymphomas in which abnormal T *lymphocytes are concentrated in the skin. The most common form is *mycosis fungoides.... cutaneous t-cell lymphoma
n. an abnormal cell present in the blood and the blood-forming organs in one type of leukaemia (lymphoblastic leukaemia). It has a large nucleus with very scanty cytoplasm and is thought to be the precursor of the lymphocyte. —lymphoblastic adj.... lymphoblast
(lymphocoele) n. a collection of lymph in the tissues, which follows injury to, or operations upon, lymph nodes or ducts.... lymphocele
n. see lymphopenia.... lymphocytopenia
n. see lymphangiography.... lymphography
n. a substance produced by lymphocytes that has effects on other cells involved in the immune system (see cytokines). An example is *interleukin 2 (IL-2).... lymphokine
(lymphocytopenia) n. a decrease in the number of *lymphocytes in the blood, which may occur in a wide variety of diseases.... lymphopenia
see Waldenstrom’s macroglobulinaemia.... lymphoplasmacytic lymphoma
n. the process of the production of *lymphocytes, which occurs in the *bone marrow as well as in the lymph nodes, spleen, thymus gland, and gut wall. The precursor cell from which lymphocytes are derived has not yet been identified.... lymphopoiesis
n. the escape of the lymph from lymphatic vessels that have been injured.... lymphorrhagia
n. an imaging scan undertaken to identify the *sentinel lymph nodes, which receive lymph drainage from a tumour and are the first to show evidence of metastasis, and to differentiate these from disease-free nodes; this is in order to plan treatment options, particularly for melanoma and breast cancer management.... lymphoscintigraphy
n. a *lymphokine that lyses various cell types, including tumour cells.... lymphotoxin
the spread of cancer cells into lymphatic or blood vessels noted on histopathological analysis of a specimen taken at biopsy or after surgical resection. It is associated with a higher risk of lymph node involvement and distant metastases.... lymphovascular invasion
see lymphoma.... non-hodgkin’s lymphoma
(TIL) a lymphoid cell that can infiltrate solid tumours. Such cells can be cultured in vitro, in the presence of *interleukin 2, and have been used as vehicles for *tumour necrosis factor in gene therapy trials for cancer.... tumour-infiltrating lymphocyte
(XLP syndrome, Duncan’s disease) a hereditary disorder of the immune system caused by a defective *sex-linked gene carried on an *X chromosome. There is uncontrolled proliferation of B-*lymphocytes in response to infection by the Epstein-Barr virus, which can lead to fulminating hepatitis or lymphoma. This condition is due to a defect in a gene, SAP, which encodes a signalling molecule found in the cytoplasm of cells.... x-linked lymphoproliferative syndrome
