[Role of the kinin and sympathetic-adrenal systems in the early stages of hypertension].

Changes in the kinin and sympatheticoadrenal systems in the early stages of hypertensive disease were studied in children and adolescents. It was shown that the kinin and sympatheticoadrenal systems take part in the development and formation of primary arterial hypertension; the degree of their changes depends on the stage of the disease. A definite connection was discovered between the kinin, sympatheticoadrenal, and enterochromaffin systems. A change in the activity of one of these systems is attended with a change in the activity of another system.
