[Early effects of the influence of ionizing radiation in relatively small doses on the neuromediator systems responding to the central regulation of the hypothalamo-pituitary-adrenal cortex system].

In experiments with mature Wistar male rats changes of mediator interrelations in different brain parts, responsible for the central regulation of the hypothalamo-pituitary-adrenocortical system, were detected at early times after whole-body X-irradiation with a dose of 12.9 mC/kg. These changes represent one of the major mechanisms leading, at later times after irradiation, to the development of syndromes related to diencephalic disturbances.
