PRELIMINARY OBSERVATIONS ON THE RELEASE OF OXYTOCIN AND VASOPRESSIN IN HUMAN SUBJECTS

Abstract

SUMMARY: 1. Oxytocic and vasopressor activity were found in human peripheral venous blood following overnight dehydration and an intravenous injection of nicotine. 2. The quantities are adequate for investigation of hypothalamic damage of moderate severity. 3. The blood levels of oxytocic activity exceed vasopressor activity.
