Hemolysis experiments with dilutions of rabbit

mammary cancer than those from nontumorous animals. The question arose : Are these findings characteristic only for red blood cells from CSH mice with mammary cancer, or are these findings also valid for other mouse strains and other tu mors, including transplants of tumors originally induced with methylcholanthrene? Experiments were performed to investigate the hemolytic behavior of erythrocytes from C8H and from C57BL mice which carried transplants of various tumors. The red blood cells were tested for hemolysis with dilutions of rabbit serum and with dilutions of suspensions of the tumors used for transplants. Data will be presented which indicate that the growth of some of these tumors affects the hemolytic behavior of CSH and C57BL erythrocytes.
