[The characteristics of the sympathico-adrenal and kinin systems in engineers in the early stages of arterial hypertension].
Overall seventy-two engine-drivers with borderline arterial hypertension (BAH) and stage I arterial hypertension (AH) were studied for the condition of the sympathoadrenal and kinin systems before and after trip. Both groups exhibited a rise in the activity of the sympathoadrenal system before trip, with still greater rise being recordable after trip. BAH and stage I AH subjects demonstrated an increased activity of the kinin system of the kidneys before trip and decreased one after trip. Suppression of the kinin system of the kidneys with simultaneous progression of pressor effects leads to decline in adaptation to physical and psychoemotional overloads in those engine-drivers presenting with early stages of AH.
