The effect of acute extracellular volume expansion on sodium chloride reabsorption in the diluting segment in man.
1. The effect of extracellular volume expansion (ECVE) during water diuresis, and of water diuresis alone, on the formation of free water in man was compared. 2. ECVE reduced free water formation at any given rate of distal delivery compared with water diuresis. Thus, ECVE depresses distal sodium chloride reabsorption. 3. This attenuation of free water formation occurred both when urine flow (V...
متن کاملEffect of sodium intake on single nephron glomerular filtration rate and sodium reabsorption in experimental uremia.
Sodium balance, clearance and micropuncture studies were performed on three groups of uremic rats in which renal mass was reduced experimentally by approximately 85%. All animals received a sodium-free synthetic diet to which a measured amount of NaCl was added. Sodium intake was 3 mEq/day in one group, 1 mEq/day in a second group and 0.13 mEq/day in the third. In the latter, the Na intake was ...
متن کاملEffect of dietary sodium reduction on red blood cell sodium concentration and sodium-lithium countertransport.
A randomized, crossover trial was carried out on the effect of moderate sodium reduction on red-blood-cell sodium metabolism. The participants were healthy high school students (mean age = 16 years, n = 33). Changes in sodium-lithium countertransport and intracellular sodium concentration were evaluated 24 days after a decrease in dietary sodium from approximately 110 to 40 mEq per day. Dietary...
متن کاملPlasma sodium concentration: bearer of false prophecies?
Occasionally measurement of the serumn or plasma concentration of sodium may give rise to falsely low results when carried out on a flame photometer or by an indirect reading ion selective electrode. The patients at risk are those with abnormally high serum concentrations of lipid or protein. These are, however, few: initially all low sodium concentrations as measured by flame photometry should...
متن کاملIndividuality of the plasma sodium concentration.
Older literature has suggested that the plasma sodium concentration is not individual, that it is neither intrinsic to an individual nor reproducible, longitudinally. We recently observed that the plasma sodium concentration is heritable. Because demonstrable heritability requires individuality of the relevant phenotype, we hypothesized that the plasma sodium concentration was substantially ind...
