Effect of Sodium Ferrocyanide and Bicarbonate on Reabsorption of Inorganic Sulfate in Renal Tubules. ∗

Summary

Sodium ferrocyanide and sodium bicarbonate have almost no effect on reabsorption of sulfate in renal tubules in the dog. These results, together with earlier studies, suggest that only anions which are reabsorbed as such through tubule cells, depress reabsorption of sulfate. This assumes, however, that bicarbonate is reabsorbed only as CO₂ and water, and not in ionic form.
