Changes in activity of stress-realizing body systems as a result of terahertz irradiation at nitric oxide frequencies in albino rats under conditions of acute stress.

We studied the effects of irradiation with teraherz electromagnetic waves at frequencies corresponding to nitric oxide emission and absorption molecular spectrum (150,176-150,664 GHz) on activity of the sympathoadrenal and pituitary-adrenal axes of the stress response in albino male rats under conditions of acute immobilization stress. It was shown that terahertz waves exert stress-limiting effect and are capable of reducing the levels of catecholamines, corticotropin, and corticosterone in male rats exposed to acute stress.
