[The effect of a psychoemotional load on the activity of the sympathetic-adrenal system in subjects with different levels of arterial pressure].

Subjects with initially increased level of arterial pressure were shown to have a higher contents of vasopressin in the blood plasma and of cortisol in the saliva. All the subjects revealed an increased systolic and diastolic blood pressure in response to a psycho-emotional load. The levels of cortisol and vasopressin did not increase at that. Neither the adrenaline level changed whereas the noradrenaline level increased. The latter increased more in the subjects with a milder form of arterial hypertension. The data obtained suggest that the reactivity of the sympatho-adrenal system is higher in the subjects with an increased arterial pressure.
