Bicarbonate reabsorption in the dog with experimental renal disease.
Renal bicarbonate reabsorption (expressed per unit of glomerular filtration rate, GFR) has been reported to be diminished in uremic man and uremic rats. Both the increases in parathyroid hormone concentrations and in natriuretic forces have been considered to play a role in this change. The increased kaliuresis per nephron observed in chronic uremia could theoretically also contribute to inhibi...
متن کاملEffects of glucose on bicarbonate reabsorption in the dog kidney.
The effects of glucose on renal bicarbonate reabsorption were investigated in the dog. The infusion of small amounts of glucose calculated to slightly exceed the renal threshold for glucose absorption increased bicarbonate reabsorption in bicarbonate loaded dogs. Galactose in similar doses also increased the reabsorption of filtered bicarbonate. This effect is not due to insulin secretion since...
متن کاملThe Renal Tubular Reabsorption of Glucose in the Normal Dog
It is known that glucose is filtered through the glomerulus in the same concentration as it is present in the water of the plasma (Walker and Reisinger, 1933), and that, its absence from the urine at normal plasma concentrations is due to the circumstance that it is reabsorbed by the tubule. In the amphibian kidney, this reabsorption is effected by the proximal segment (Walker and Hudson, 1937)...
متن کاملRenal bicarbonate reabsorption and hydrogen ion excretion in normal infants.
After acute administration of ammonium chloride, infants 1 to 16 months of age were similar to older children in their capacity to acidify their urine. The infants had a higher rate of excretion of titratable acid and a lower rate of excretion of ammonium but were similar in their rate of excretion of total hydrogen ion.Bicarbonate titrations performed in infants during the first year of life d...
متن کاملRenal tubular reabsorption of inorganic sulfate in the normal dog.
Inorganic sulfate is formed during the metabolism of the sulfur-containing amino acids. Although its exact functions are not well understood, the body nevertheless maintains a basic store of circulating sulfate at all times. Its plasma level, although low, is fairly constant, being maintained in the normal dog within limits of 1.2 and 1.8 millimols per liter. The maintenance of plasma concentra...
