title: [Blood vasopressin concentration is patients of different ages with hypertension].
abstract: The concentration of blood vasopressin was investigated in apparently healthy persons and in patients with I--II degree hypertension, aged from 20 to 80 years. Vasopressin concentration was determined by the biological method according to the antidiuretic effect of ethanol-anesthetized and constantly hydrated rats on an original 5-channel apparatus. The results obtained showed the blood vasopressin concentration to increase with age. In patients with the I--II degree hypertensive disease the mentioned concentration was significantly higher than in healthy persons of the same age. Close correlation coefficient was revealed between the blood vasopressin concentration and minimal arterial blood pressure values.
