| lympho- | Lymph. Origin: L. Lympha, spring water (05 Mar 2000) |
|---|---|
| lymphoadenoma | 1. Obsolete term for an enlarged lymph node. 2. Obsolete term for Hodgkin's disease. (05 Mar 2000) |
| lymphoblast | <haematology> Often referred to as a blast cell. Unlike other usages of the suffix blast a lymphoblast is a further differentiation of a lymphocyte, T or B, occasioned by an antigenic stimulus. The lymphoblast usually develops by enlargement of a lymphocyte, active re entry to the S phase of the cell cycle, mitogenesis and production of much mRNA and ribosomes. (18 Nov 1997) |
| lymphoblastic | Pertaining to the production of lymphocytes. (05 Mar 2000) |
| 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) |
| lymphoblastic lymphoma | <tumour> A diffuse lymphoma in children, with supradiaphragmatic distribution and T lymphocytes having convoluted nuclei; many patients develop acute lymphoblastic leukaemia. (05 Mar 2000) |
| lymphoblastoma | <tumour> A form of malignant lymphoma in which the chief cells are lymphoblasts. Origin: Lymphoblast + G. -oma, tumour (05 Mar 2000) |
| lymphoblastosis | The presence of lymphoblasts in the peripheral blood; sometimes used as a synonym for acute lymphocytic leukaemia. Origin: Lymphoblast + G. -osis, condition (05 Mar 2000) |
| lymphocele | Cystic mass containing lymph from diseased lymphatic channels or following surgical trauma or other injury. (12 Dec 1998) |
| lymphocerastism | The process of formation of cells in the lymphocytic series. Origin: Lympho-+ G. Kerastos, mixed, mingled (05 Mar 2000) |
| lymphocinesis | 1. Circulation of lymph in the lymphatic vessels and through the lymph nodes. 2. Movement of endolymph in the saemicircular canals of the inner ear. Synonym: lymphocinesis, lymphocinesia. Origin: Lympho-+ G. Kinesis, movement (05 Mar 2000) |
| lymphocryptovirus | A genus of the family herpesviridae, subfamily gammaherpesvirinae, consisting of viruses similar to the type species human herpes virus 4 (herpes virus 4, human), better known as the epstein-barr virus. (12 Dec 1998) |
| lymphocyst | Synonym: lymphocele. Origin: Lympho-+ G. Kystis, bladder (05 Mar 2000) |
| lymphocytapheresis | Separation and removal of lymphocytes from the withdrawn blood, with the remainder of the blood retransfused into the donor. Synonym: lymphapheresis. Origin: Lymphocyte + G. Aphairesis, a withdrawal (05 Mar 2000) |
| lymphocyte | <haematology> White cell of the blood that are derived from stem cells of the lymphoid series. Two main classes are recognised, T and B lymphocytes, the latter responsible (when activated) for production of antibody, the former subdivided into subsets (helper, suppressor, cytotoxic T-cells) and responsible both for cell-mediated immunity and for stimulating B-cells.
