[The effect of hydrocortisone on lipid mobilization].

Acetate-1-C14 was administered to rats 18 hours before the administration of hydrocortisone for the purpose of studying the action of this hormone on lipid mobilization. Blood plasma and adipose tissue lipid content failed to change, but it decreased in the liver. Hydrocortisone accelerated the elimination of the label from lipids of the liver, did not alter the radioactivity of blood plasma lipids and stimulated accumulation of endogenous label in the lipids of adipose tissue. An acceleration of lipid catabolism in the liver and of lipid anabolism in the adipose tissue was accompanied by stimulation of gluconeogenesis in the liver from the endogenous precursors. In discussing the materials the primary role of intensification of gluconeogenesis in the liver in the mechanism of the regulating action of glucocorticoids on lipid metabolism was postulated.
