title: Macrophage migration inhibition-activity after implantation of methylcholanthrene-induced sarcoma, Ehrlich ascites cancer or mouse ascites hepatoma-134 cancer cells in mice.
abstract: Cells from methylcholanthrene-induced tumor (MC-tumor), Ehrlich ascites cancer or mouse ascites hepatoma (MH-134) were subcutaneously implanted in dorsal area of mice to examine the specific cell mediated immunity following implantation. The migration index (MI) of lymphocytes was determined at various time periods after cell transplantation. The MI-activity increased under all three implantations, reached maximum at a certain period, decreased gradually and disappeared. The maximum MI-activity coincided with the proliferation period of the implanted tumor cells. This peak occurred on the tenth postimplantation day with MC-tumors, on the fifth day with Ehrlich ascites cancer and on the sixth day with MH-134 cancer. In lymphoid tissues of animals with MC-tumor and Ehrlich ascites cancer, strong MI-activity appeared early in the regional axillary lymph nodes, while weak activity was observed consistently in the distant mesenterial lymph nodes. The MI-activity of the splenic lymphoid cells resembled the axillary lymph nodes cell activity. The MI-activity of venous blood lymphoid cells was parallel to the average value of lymphoid cells of the spleen and axillary and mesenterial lymph nodes.
