Abstract
Summary
1. The effect of increasing renal arterial pressure on sodium and calcium excretion in an isolated kidney was studied. 2. Increasing renal arterial pressure by about 50 mm Hg caused a significant increase in both the absolute and fractional excretion of sodium and calcium in the absence of consistent changes in GFR or RBF. 3. A significant correlation was found between calcium and sodium excretion and provides additional evidence that the transport of these two cations is linked.
