ESTIMATION OF ANTIDIURETIC HORMONE IN THE URINE OF HEALTHY SUBJECTS AND PATIENTS WITH INAPPROPRIATE SECRETION OF VASOPRESSIN (SCHWARTZ-BARTTER SYNDROME)

Abstract

ABSTRACT The excretion of antidiuretic hormone in the urine was determined in healthy subjects and patients with inappropriate secretion of vasopressin. The antidiuretic hormone was extracted by means of an ion exchanger and assayed in hydrated rats under alcohol anaesthesia. The urine of patients with inappropriate antidiuretic hormone secretion shows a higher antidiuretic activity than that of normal subjects.
