title: [Participation of adrenal hormones in the genesis of arterial hypertension of hypothalamic origin].
abstract: Continuous many-hour stimulation of the hypothalamic negative emotiogenic centres (ventromedial nuclei) evoked a stable arterial hypertension with a peculiar phasic dynamics of the adrenal secretory activity in waking immobilized rabbits. Bilateral extirpation of the adrenal glands decreased the initial level of the average arterial pressure, inhibiting development of stable arterial hypertension. Many-hour stimulation of the mentioned structures also produced stable arterial hypertension in adrenalectomized rabbits if preceded by the administration of hydrocortisone together with adrenaline. Against the background of separate administration of hydrocortisone and adrenaline to adrenalectomized rabbits, many-hour stimulation of the ventromedial hypothalamus evoked a short-term rise in the arterial pressure. A conclusion was drawn that activation of hormones of the adrenal cortical and medullary layers played an important part in the formation of stable arterial hypertension in rabbits under continuous many-hour stimulation of the hypothalamic negative emotiogenic centres.
