title: [The individual characteristics of the postradiation reaction of the cyclic nucleotides in rat thymocytes].
abstract: It was shown that X-irradiation of rats (4.3 Gy), which were preliminarily divided into two groups by the neutrophilic reaction in the peripheral blood to the effect of a three-hour immobilization, induced different reactions of the cyclic nucleotide system. Thus, in animals hyper-reactive to stress radiation injury to the above system was severe: relative reactivity made 22.8% of the initial value, and adenylate cyclase ability to respond to a hormonal stimulus was drastically inhibited. In hyporeactive animals, relative reactivity of adenylate cyclase system after irradiation made 47% throughout the same period of observation; inhibition of adenylate cyclase activity was also less pronounced.
