    Amiloride inhibits the vasopressin-induced increase in epithelial water permeability

    The vasopressin (VP)-induced increase in water permeability in high-resistance, amphibian epithelia is not altered by the abolition of net Na+ flux caused by amiloride added to the apical bathing medium. In this ...

    Kinetics of tracer flows and isotope interaction in an ion exchange membrane

    The thermodynamic formulation of isotope interaction (coupling of abundant and tracer isotope flows) has been tested in a highly permselective anion exchange membrane in the absence of significant electroosmos...

    Flux Ratios and Isotope Interaction in an Ion Exchange Membrane

    IN spite of the widespread use of radioactive tracers in the study of permeation of biological tissues, it is well known that the permeability coefficient derived from tracer exchange may differ appreciably fr...
