1909 Cent. Dict. Suppl. Lymphoblast.

1935 Jrnl. Amer. Med. Assoc. 7 Sept. 765/2 Lymphoblasts approach the structure of myeloblasts.

1962 Lancet 27 Jan. 206/2 In the early stages of the production pathway, the lymphocytes are large and possess an intensely basophilic cytoplasm; these are the cells which have often been called lymphoblasts.

1905 Lancet 12 Aug. 465/2 Dr. Jones concluded,..secondly, that apparently a lymphoblastic marrow was usually accompanied by an increased production of erythroblasts, but that, on the other hand, a leucoblastic marrow was not associated with increased erythroblastic production.

1961 Lancet 5 Aug. 291/2 In 2 cases biopsy of a lymph-gland was undertaken and reported as lymphoblastic lymphoma.

1920 Jrnl. Urol. 4 137 (title) Lympho-blastoma (lympho-sarcoma) of the prostate.

1926 Jrnl. Amer. Med. Assoc. 17 Apr. 1185/1 Lymphoblastoma, a name considered by some as synonymous with malignant lymphoma..may include lymphatic leukemia (lymphocytic and lymphoblastic), aleukemic lymphatic leukemia (pseudoleukemia, aleukemic lymphadenosis), lymphocytoma, Hodgkin's disease (lymphogranuloma), lymphadenoma, lymphomatosis, lymphosarcoma, round cell sarcoma, leukosarcoma and lymphadenosarcoma.

1970 S. D. Kobernick tr. P. Masson Human Tumors ii. x. 353 The structure is very simple: a chaotic mixture of small cells with round nuclei, larger in lymphoblastomas than in lymphocytomas.

1901 C. Watson Encycl. Medica VII. 196 Among them [sc. synonyms of lymphadenoma] are adenia, lymphadenia, lymphogenic diathesis, lymphadenosis, lymphoma, lymphomatosis, pseudo-leukemia, lymphosarcoma, and the non-committal Hodgkin's disease.

1909 Practitioner Nov. 656 The unilateral distribution of renal tuberculosis..is explained by lymphogenous infection.

1935 N. P. Sherwood Immunol. iii. 59. The four avenues [of spread of infectious agents] commonly mentioned are surface spread, dissemination by way of the lymphatics (lymphogenous), blood stream (hematogenous) and direct extension to adjacent tissues.

1969 D. C. Dumonde et al. in Nature 4 Oct. 38/1 In the guinea-pig these four phenomena are mediated by cell-free soluble factors, which are generated during interaction of sensitized lymphocytes with specific antigen, but which are expressed without reference to immunological specificity. The generic term ‘lymphokine’ is suggested to describe this group of biological activities.

1973 Nature 2 Mar. 22/2 When T cells are activated by antigen, they proliferate..but they..do not become antibody-secreting cells. They do, however, secrete a variety of non-antigen~specific factors (‘lymphokines’) such as migration inhibition factors (MIF), chemotactic factors, cytotoxic factors and mitogenic factors, at least some of which presumably play a role in cell-mediated immune responses, for which T cells are primarily responsible.

1974 Sci. Amer. Apr. 36/2 Transplantation antigens and other foreign material..stimulate the production and release of ‘sensitized’ lymphocytes, or effector cells... In addition to killing graft cells directly the sensitized lymphocytes secrete a variety of chemical agents called lymphokines, some of which act directly on the foreign cells and some of which attract other leukocytes..which digest damaged cells and cell fragments.

1909 Cent. Dict. Suppl. Lymphopenia.

1921 Lancet 10 Dec. 1205/2 The blood content passes from exhibiting a lymphopænia to a lymphocytosis.

1964 L. C. Martin Clin. Endocrinol. (ed. 4) i. 35 A leucocytosis of 10–15,000 per c.mm. is usual with a polymorph excess, lymphopenia and eosinopenia.

1918 T. L. Stedman Pract. Med. Dict. (U.S. ed. 5) 569/1 Lymphopoiesis,..the formation of lymphocytes.
