Renal 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 کاملBicarbonate 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 کاملEffect of plasma CO2 tension on renal tubular reabsorption of bicarbonate.
S INCE the extensive studies of Pitts and coworkers (1-3) defined the characteristics of bicarbonate reabsorption in the normal subject, very little additional information has appeared concerning the nature of this transport system or its regulation. It was suggested then (2) that a dual process existed for the reabsorption of bicarbonate. A specific transport system in the proximal tubule was ...
متن کاملControl of proximal bicarbonate reabsorption in normal and acidotic rats.
This free-flow micropuncture study examined the dependence of bicarbonate reabsorption in the rat superficial proximal convoluted tubule to changes in filtered bicarbonate load, and thereby the contribution of the proximal tubule to the whole kidney's response to such changes. The independent effects of extracellular fluid (ECF) volume expansion and of acidosis on proximal bicarbonate reabsorpt...
