More Information
Summary:Hydrodynamic permeability, electro-osmotic permeability, streaming potential and streaming current have been measured across urinary bladder membranes using aqueous solutions of urea, thiourea, glucose and creatinine. Results have been analysed by using the methodology of non-equilibrium thermodynamics. It has been found that non-linear relations exist between fluxes and forces. Higher-order phenomenological coefficients have been determined and Onsager's reciprocal relations were found to be valid. The stability of the steady state and physiological aspects of electrokinetic phenomena are also discussed.
