[Adaptive-compensatory reaction of the brain to irradiation].
In totally irradiated chick and rat embryos, young chicks and rats structural functional activity of the subcellular reparative processes in the brain cortex was studied. The animals were given an irradiation dose of 600 and 1,200 rad. In embryo-genesis and in early postnatal period, the adaptive compensatory response in shown after X-ray irradiation to be characterized by subcellular changes and organell hypertrophy of the neurons in the CNS accompanied by disturbances in metabolic and synthesis processes. Ultrastructural regeneration goes side by side with the destructive processes in them.
