Corticotropin (ACTH) and Cortisone.
—J. S. Robson, D. B. Horn, and C. P. Stewart (Edinburgh) reported on the action of cortisone and corticotropin (ACTH) on the dehydroascorbic acid of human plasma. A. Pittoni and C. R. Rossi (Padua) compared the action of corticotropin with that of total prehypophysial alkaline extracts on the metabolism of the ketonic bodies in liver and kidneys. Both actions are similar in the kidneys, but in the liver that of corticotropin is limited to a slight reduction in the production of carbon
