abstract：:In vivo microperfusion techniques were used to investigate the role of Na+-H+ exchange in the efferent ducts of the rat. Individual efferent ducts were perfused with a Krebs-Ringer bicarbonate solution (KRB) containing 0, 1, 3, 5 or 7.5 mM amiloride. Concentrations of 1-5 mM amiloride inhibited fluid reabsorption from...
