[Dependence of the circadian changes in stressor response of the rat hypophyseal-adrenocortical system on the stress intensity].
Circadian responses of the hypophyseal-adrenal axis to stress were greater is the PM as compared with AM after small stress intensity, but it were similar after high stress intensity. Was shown to depend on the intensity of the stress factor. The circadian variations of the adrenal glands response to the ACTH seem to play a major role in determining the character of the hypophyseal-adrenal axis response to stress.
