Abstract: | The effect of 57Co-bleomycin on the immune response induced by sheep red cells was studied on mice. It was found that the immune response was not suppressed when the labeled antibiotic was used in a single dose of 5-20 mg/kg. By the 5th day the level of 57Co-bleomycin in the skin, thymus and blood was 3-10 times higher than that of 57CoCl2 and in the spleen it was 1.3-1.5 times higher. |
