THE PERMEABILITY OF PINCHED‐OFF NERVE ENDINGS TO SODIUM, POTASSIUM AND CHLORIDE AND THE EFFECTS OF GRAMICIDIN

THE PERMEABILITY OF PINCHED‐OFF NERVE ENDINGS TO SODIUM, POTASSIUM AND CHLORIDE AND THE EFFECTS... Abstract— 1 The passive permeability of synaptosomes to ions was measured by a light‐scattering technique. Synaptosomes were freely permeable to acetate, HCO3_, SCN−and NH4+ and were impermeable to choline and SO42‐. 2 Gramicidin D selectively increased the permeability of synaptosomes to Na+ and K+ ions. 3 The relative permeabilities of Na+, K+ and Cl−, measured in the presence of a number of more permeant counter‐ions, was in the ratio 1:19:12. These values are discussed in terms of the source of the resting potential. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Neurochemistry Wiley
