Popis: | The water diffusion across human erythrocyte membrane has been studied on intact cells and resealed ghosts by a doping NMR technique. Although the water exchange time of ghosts was longer than that of erythrocytes, no significant differences in their diffusional permeability were noticed for temperatures in the range 2-43 degrees C. Contrary to what was previously noticed in erythrocytes, no significant increase in the water exchange time of ghosts in the acid range of pH occurred. |
