Urinary Excretion of Neutral 17-Ketosteroids by Normal Dogs

Abstract
Neutral 17-ketosteroids were detd. by the Callow method after Girard separation, and also by use of the Gibson-Evans equation. Both methods gave the same results, indicating that normal dogs excrete less than 1 mg. neutral 17-ketosteroids per day. Spectrochemical evidence indicates that even these values may be too high. No sex difference was observed and no increase in excretion occurred following ACTH admn.
