Effect of antihypertensive drugs on neonatal blood pressure.
This study evaluates the perinatal outcome of infants born to ninety-five mothers with hypertension in pregnancy whose blood pressure was treated in a double blind trial comparing clonidine hydrochloride (C) and alpha-methyldopa (A). There were no fetal deaths and two neonatal deaths, giving a perinatal mortality of 2%. There was no significant difference between Groups C and A with regard to the gestation or weight at birth, incidence of intrauterine growth retardation, or condition at birth as judged by Apgar scores and acid-base status. No infant in either group developed significant hypotension or rebound hypertension. The blood pressure was not significantly different between Groups C and A, and controls. In each of these three groups there was a similar significant rise in systolic blood pressure with age.

The renin-angiotensin system and hypertensive left ventricular hypertrophy in the rat.
The relationship between left ventricle-to-body weight ratio (LV/BW), mean arterial pressure (MAP, the average of 12 h of intra-arterial monitoring in conscious animals) and plasma renin activity (PRA) was assessed at 12 weeks after unilateral clipping or sham operation in twenty-four one-kidney rats and twenty-six two-kidney rats. The degree of hypertension and left ventricular hypertrophy were similar in one-kidney and two-kidney groups. There was a close linear relationship between LV/BW and MAP which was similar in one-kidney and two-kidney rats. PRA was significantly elevated only in two-kidney rats and was not related to the degree of hypertrophy after accounting for the effect of PRA on MAP. These data suggest that activation of the renin-angiotensin system does not contribute directly to myocardial hypertrophy in rats with renal-clip hypertension.
