Kinetic Analysis of the Permeability of Human Erythrocytes to NH4Cl
A densimeter technique was used to make a kinetic analysis of the rate of swelling of human erythrocytes suspended in 1% NaCl following successive additions of NH(4)Cl. Two series of experiments were performed, one in the absence of and the other in the presence of 6 x 10(-4)M NaHCO(3). An analysis of the data using Widdas's equations gave a family of curves in each instance. When LeFevre's equ...

Physiol. 222(3): 1004-1013. 1972.We have developed a continuous-flow rapid-reaction apparatus, using a glass pH electrode, capable of measuring changes in pH of ho.01 unit as early as 0.01 set after mixing. With this apparatus we have measured t...

متن کاملPermeability of Erythrocytes to Radioactive Potassium
The diffusion coefficients for the exchange of potassium across the membrane of erythrocytes of humans, rats, and rabbits have been determined by the use of artificially radioactive potassium, both into and out of the erythrocytes both in vitro and in vivo. The diffusion coefficients found in minutes(-1) were 0.2 to 0.25 x 10(-3) for human, 0.32 to 0.665 x 10(-3) for rabbits, and 1.0 x 10(-3) f...
متن کاملDiffusional water permeability of human erythrocytes and their ghosts
The diffusional water permeability of human red cells and ghosts was determined by measuring the rate of tracer efflux by means of an improved version of the continuous flow tube method, having a time resolution of 2-3 ms. At 25 degrees C, the permeability was 2.4 x 10(3) and 2.9 x 10(3) cm s-1 for red cells and ghosts, respectively. Permeability was affected by neither a change in pH from 5.5 ...
