[Leukemogenesis and bone marrow hematopoietic disorders in baboons with immunoblastic malignant lymphomas of B- and T-cell types].
Leukemization in baboon B- and T-cell immunoblastomas was investigated. Immunologic identification of tumor was carried out using standard immunological and cytochemical tests, e. g. identification of several types of E-rosette forming lymphocytes, surface and cytoplasmic immunoglobulin-carrying lymphocytes and assay of such acid hydrolases as acid phosphatase, acid alpha-naphthyl acetate esterase and beta-glucuronidase in lymphoid cells. Leukemization of immunoblastomas with bone marrow infiltration by tumor immunoblasts and the appearance of the latter in peripheral blood were observed rather frequently--in 7 of 10 cases of B-cell and in all 4 cases of T-cell immunoblastoma. Immunoblastoma progression was accompanied by a rise in lymphoid element level in peripheral blood and a lesser increase in bone marrow. At terminal stage, both patterns of immunoblastoma sometimes involved the development of leukemoid reactions of a myeloid type and disturbances in bone marrow hematopoiesis which manifested themselves by mild anemia and a slightly pronounced failure to produce platelets.
