Effect of saline infusion on urinary calcium excretion in essential hypertension

Abstract

Urinary excretion of sodium and calcium was ex­amined in hypertensive (n = 8) and normotensive (n = 7) subjects following infusion of 2% saline at a rate of 11 mL/min for 90 min. The urinary sodium excretion was 204 ± 38 (mean ± SEM) //Eq/min in normotensives and 233 ± 28 //Eq/min in hyperten­sives before infusion of saline and increased maxi­mally to 499 ± 114 //Eq/min (P
