Potassium accumulation occurred in leached slices of the inner medulla of the dog kidney incubated under anaerobic conditions at 37°C with glucose as substrate, but was blocked by inhibitors of glycolysis. Aerobically, only slight accumulation occurred with succinate as substrate at 37°C, and this was blocked by dinitrophenol. These findings were in contrast to those obtained with kidney cortex slices under the same conditions.
