Quantitative investigation of the changes in the cell composition of the spleen during the growth of Worker's carcinosarcoma.
The weight of the spleen and its cell composition as a function of the weight of the tumor was studied during the development of Worker's carcinosarcoma. The progression of the dependence is presented in the appropriate mathematical form. It is shown that with development of the process of tumor enlargement, erythro- and myelopoiesis are intensified in the spleen. The overall quantity of erythroblastic elements reaches a maximum value when the weight of the tumor reaches 30 g and subsequently remains at the same level. The kinetic curves of the changes in the number of lymphocytes in the spleen and also their graphical dependence on the weight of the tumor are of an extreme character. At late stages in the development of the tumor, the number of cells of the granulocyte type begins to increase.
