HYPOPHYSEAL AND ADRENAL INTERRELATIONSHIPS AND CARBOHYDRATE METABOLISM

Abstract
Adm. of highly purified extracts of the adrenal cortex was effective in maintaining normal or supernormal blood sugar and liver glycogen levels in hypophysectomized rats; muscle glycogen was also kept at approximately normal values. Small amts. of extract, e.g., 6 cc. daily, readily produced elevations of blood sugar, and amts. totalling 24-30 cc. daily given in small, frequent doses markedly influenced the storage of liver glycogen. Furthermore, cortico-adrenal extract restored normal blood glucose and liver glycogen values in hypophysectomized rats which had been carbohydrate-depleted by a 12-hr. fast before injs. were begun.
