[Morphofunctional characteristics of the cells of the APUD system of the adrenal glands and the duodenum in the cerebral form of acute radiation sickness].

Changes of a phase nature develop in the APVD system cells of rats, dogs, and monkeys exposed to electron radiation of doses inducing a cerebral form of radiation sickness. These changes in the morphofunctional status of APVD system cells may be considered as a syndrome displaying acute radiation apudopathies.
