Sodium Movement in High Sodium Feline Red Cells
The transport of Na in the cat red cells has been studied under various experimental conditions. The unidirectional radioactive Na influx increased with increasing temperature until it reached a maximum value at 37 degrees C +/- 2 degrees C and then decreased with a further increase in temperature. Errors stated in this paper represent 1.0 standard errors of the mean. The apparent activation en...
متن کاملFurther Studies of Sodium Transport in Feline Red Cells
The transport of radioactive sodium in high sodium cat red blood cells has been studied under various experimental conditions. It was found that iodoacetate (IAA) and iodoacetamide (IAM) inhibit Na influx by 50% whereas NaF has no effect. Reversible dyes, such as methylene blue (Mb), also inhibit this influx by 60%. Both IAA and Mb effects show a lag period of about 40 min. Cell starvation abol...
متن کاملSulfate Flux in High Sodium Cat Red Cells
The transport of radioactive sulfate in cat red cells has been studied. The rate constant for (35)SO(4) inward movement under steady-state conditions is 0.24 +/- 0.02/hr. This movement was found to be sensitive to osmotic changes in cell volume and to the nature of anions in the incubation medium; it increases with increasing cell volume and decreases with decreasing cell volume. The anions SCN...
متن کاملLow sodium cotransport in red cells with physiological internal sodium concentration in essential hypertension.
Ouabain-resistant Na and Li effluxes in erythrocytes from 18 normal subjects and 19 hypertensive subjects were studied in fresh cells that contained about 9 mmol Li and 2.5 or 6.5 mmol Na per liter of erythrocytes after intact cells had been incubated for 5 hours in 110 mM Li, 40 mM Na medium, with or without ouabain 10(-4) M. Outward Na cotransport was estimated at both internal Na concentrati...
متن کاملSodium renders endothelial cells sticky for red blood cells
Negative charges in the glycocalyx of red blood cells (RBC) and vascular endothelial cells (EC) facilitate frictionless blood flow through blood vessels. Na(+) selectively shields these charges controlling surface electronegativity. The question was addressed whether the ambient Na(+) concentration controls RBC-EC interaction. Using atomic force microscopy (AFM) adhesion forces between RBC and ...
