LEUKEMOID REACTION IN SOME DISEASES OF CATTLE
The article highlights several aspects of the problem being studied. First of all, given the frequency distribution of different forms of hemoblastoses of cattle according to the results of pathological studies (V. V. Smirnova). It is shown that the most frequently (47.9 per cent) recorded lymphocytic leukemia; 27.3 cases lymphosarcoma. When lymphocytic leukemia marginal fluctuations in the concentration of cells was mainly in leukemic values. The tumor form of leukemia was accompanied by normal blood counts. The coincidence of hematological and histological studies on leukemia was the highest when the content of leukocytes in 1 l of blood within 30,0-50,0 • 109 cells. Thus, the percentage of divergence of the diagnoses is inversely proportional to the increase in the number of leukocytes in the blood. Up to 5-8 % of hematologically investigated BLV-infected animals with leukemogenesis reactions belong to the category of patients with leukemia.
