INORGANIC PHOSPHATE AND ACID EXCRETION IN THE POSTABSORPTIVE PERIOD

Micropuncture Study of Inorganic Phosphate Excretion

The mechanism by which the mammalian kidney excretes inorganic phosphate has not been fully elucidated. The only micropuncture data available are those of Walker and Hudson (1), and they deal with the mode of phosphate excretion in two amphibian species. These investigators reported that the inorganic phosphate concentration rises progressively along the proximal and distal nephron of the frog ...

Urinary Excretion and Serum Concentration of Inorganic Phosphate in Man.

Renal excretion of inorganic phosphate in newborn infants.

Because of the important role phosphate plays in many body functions and since phosphate absorbed in excess of body needs is excreted mainly by the kidneys, detailed studies of renal excretion of phosphate have been made in dogs and in adult human subjects, especially by Pitts and his coworkers (1-3). Mechanisms involved in renal excretion of phosphate in young infants are of interest for addit...

Effects of phosphate loading and depletion on the renal excretion and reabsorption of inorganic phosphate.

A number of studies have indicated that parathyroid extract increases the renal excretion of phosphate (1-6). This effect appears to result from a depression of the renal reabsorption of phosphate (6). Endogenous secretory activity of the parathyroid glands has been related to the extracellular concentration and/or the dietary intake of calcium and phosphate. Although dietary variations of thes...

Effect of splanchincotomy on the renal excretion of inorganic phosphate in the anaesthetized dog.

The effects of acute i.v. inorganic phosphate (Pi) loading were studied on nembutalized mongrel dogs previously subjected to unilateral splanchnicotomy ("renal denervation"). GFR (51Cr-EDTA) was not different on the intact and the denervated side, while urine output (V), sodium excretion (UNaV), and urinary excretion (UPiV) of inorganic phosphate of denervated kidneys were significantly increas...
