THE TUBULAR REABSORPTION OF XYLOSE IN THE NORMAL DOG

Abstract

The tubular reabsorption of xylose was examined by the simultaneous detn. of xylose and creatinine clearances at various arterial plasma glucose concs. The elevation of the plasma glucose to the level of frank glycuresis completely and reversibly blocks the reabsorption of xylose. In the dog all xylose is reabsorbed evidently by an active tubular process which is identical with that responsible for the reabsorption of glucose.
