title: [Correction of arterial pressure in rats with hereditary hypertension by altering catecholamine metabolism in early ontogeny].
abstract: In a newly developed rat strain with inherited stress-sensitive arterial hypertension (ISSAH) an attempt was made to reduce arterial blood pressure by L-DOPA injections during a short time period of the early ontogenesis. It was shown that L-DOPA injections to rats on days 7-9 or 14-16 of life had no effect. The same procedure performed on 21-23 or 21-25-day-old rats was followed by a decrease in the basal and stress-induced arterial blood pressure levels, measured in adulthood. Injections of dopamine-beta-hydroxylase inhibitor (FLA-59) with parallel L-DOPA administration completely blocked the blood pressure decreasing effect. It can be suggested that injections of L-DOPA in the 4th week of post-natal life reduce the blood pressure level in ISSAH rats by enhancing the rate of brain noradrenaline biosynthesis.
