[Energy metabolism during stressful exposures (ionizing radiation), its self-regulation and correction].
Normal hormonal regulation of energy metabolism is mainly realized by glucocorticoids and insulin, their physiological antagonist. Under the effect of different extremal factors (including ionizing radiation) there arises non-specific stress, a syndrome the main component of which is the hyperfunction of glucocorticoids--the intermediate hormonal link in the stress reaction. Stimulation of hypercorticism by administering hydrocortisone to intact animals as well as its stimulation by administering this preparation to irradiated animals causes development and intensification of inhibition and uncoupling of the oxidative phosphorylation as well as disturbance in adenylic nucleotides metabolism. The administered insulin, softening the reaction of hypercorticism and changing the ratio of the hormone levels in favour of insulin, weakens essentially the stress (ray) disturbances in the energy metabolism.
