Abstract
Summary
(1) Radioactive isotopes of sodium and potassium furnish a new method of study of the physiology of the adrenal cortex. (2) Adrenalectomized rats, unsupported by salt treatment, have an increased total sodium excretion and increased rate of excretion of administered radioactive sodium when contrasted with normal animals; the reverse is true of potassium. (3) Simple access to a 1% solution of table salt enables adrenalectomized rats to handle sodium and potassium in a way resembling that of normal rats.
