Abstract
Summary
(1) Intravenous administration of highly purified arginine-vasopressin in man is associated with a significant increase in plasma concentration of free 17-OHCS.
(2) Highly purified lysine-vasopressin causes higher plasma 17-OHCS levels than highly purified arginine-vasopressin when administered by means of an intravenous injection.
(3) Increase in plasma concentration of free 17-OHCS observed when Pitressin is administered in man can be completely accounted for by the vasopressin content of Pitressin.
The authors wish to express appreciation to Daniel W. Clink, Francis A. Esposito, and Raymond W. Patrick for technical assistance.
