Dietary sodium, erythrocyte sodium concentration, sodium-stimulated lithium efflux and blood pressure.
1. There was a significant positive relationship between sodium-stimulated lithium efflux and systolic blood pressure (r = 0.512) in erythrocytes of black school children. Weight was also positively and significantly correlated with blood pressure. Although erythrocyte sodium concentration did not bear any significant relationship with blood pressure, it did bear significant inverse relationshi...
متن کاملSodium turnover in irradiation hypertension.
1. Changes in sodium turnover in experimental hypertension were studied by tracer kinetic methods after injection of the long-lived radioisotope "Na. 2. In rats treated with renal irradiation, the pre-hypertensive latent period is characterized by a modified distribution of body sodium which can be interpreted as a transfer from peripheral stores to a more centrally located pool. Before the dev...
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 کاملErythrocyte Sodium Transport in Dialyzed Uremic Patients
To investigate the status of the Na+ concentration and ionic fluxes in red cells of human subjects with dialyzed chronic uremia, the authors measured the Na(+)-K+ pump activity as well as Na(+)-K+ cotransport (CoT), Na(+)-Li+ countertransport (CTT) and Na+ passive permeability in erythrocytes from 37 normal subjects and 23 chronic uremic patients receiving maintenance hemodialysis. The mean int...
متن کاملErythrocyte sodium transport in chronic renal failure.
1. Erythrocyte sodium, sodium transport (ouabain-sensitive efflux rate of sodium, OM& and ouabain-sensitive efflux rate constant of sodium, "KONL.), sodium-potassium activated ouabain-sensitive adenosine triphosphatase (Na+,K+-ATPase) activity and ['Hlouabainbinding capacity were measured in 15 patients with chronic ren'al failure and in 10 healthy subjects. 2. As a group, patients with chronic...
