1. The transport of potassium across the distal tubular epithelium was studied in vivo in rats on a normal potassium intake and in rats in which distal tubular potassium secretion was either stimulated by potassium loading or the I.V. administration of a 5% sodium bicarbonate solution or in which potassium secretion was suppressed by dietary deprivation of potassium or sodium.2. (42)K was used to measure unidirectional fluxes across the luminal and peritubular cell membranes and to assess the… CONTINUE READING
