[The individual postradiation reactions of cyclic nucleotides in the lymphoid cells of the rat spleen].
X irradiation (4.3 Gy) of rats was shown to cause different reactions of the cyclic nucleotide system in differently reactive animals which was determined by the neutrophilic response in the peripheral blood after three-hour immobilization. Changes in the cyclic nucleotide content and in the activity of adenylate cyclase were found to occur in both hyper- and hyporeactive animals 24 h after irradiation. In hyperreactive animals, however, these changes were more pronounced: a relative ability of adenylate cyclase to be activated in hyperreactive animals made 30%, and 52% in hyporeactive animals. The cAMP content in lymphocytes of the spleen of hyporeactive rats was twice as high as that in hyperreactive animals.
