[Effect of iodobenzoteph and cytostasan on several immune responses in animals].

Tests staged on line-bred mice immunized with sheep erythrocytes brought evidence that cystostasan and iodobenzoteph cut down the number of antibody-forming cells both with the primary and secondary immune response. The maximal effect becomes manifest following introduction of the drugs on the 1--2nd day after immunization of the animals. Iodobenzoteph brings down the number of hemopoietic stem cells colonies while cytostosan leaves them unchanged.
