Studied was the change in the oxidase activity of ceruloplasmin (CP) upon the treatment of chickens with gamma rays of 60Co at 1, 2, 3, 5, 7, 10 Gy and dose power of 0.7 per min. The minimum of the oxidase activity of CP at 3 G was found to be 0.014 AE, which, upon raising (higher doses) reached 0.044 AE. Serum copper also rose upon raising the rate of treatment--from 2.09 op to 3.76 microM. Birds that were vaccinated and treated at 4 G showed on the 15th and the 40th day a drop of the oxidase activity of CP from 0.015 AE for the control group to 0.012 AE for the experimental groups. Blood copper rose from 2.55 microM to 3.67 microM.
