title: [5-nucleotidase activity in rat leukocytes, erythrocytes and blood serum during radiation sickness].
abstract: A study of 5-nucleotidase activity in the formed elements and blood serum of rats 1, 3, 7, 15 and 30 days after X-irradiation has demonstrated that it was increased in leukocytes at early times and inhibited at later times of the development of radiation sickness. In erythrocytes, inhibition of 5-nucleotidase activity was most pronounced on the 3d day. In blood serum, the enzyme activity was virtually invariable. The addition of ATP to the incubation medium normalized 5-nucleotidase activity.
