we conclude that 1 ) na+ absorption across the rabbit trachea is ouabain sensitive , 2 ) the entry step for na+ across the luminal membrane is amiloride sensitive , 3 ) cl- secretion induced by amiloride or luminal na+ replacement probably reflects a more favorable chemical gradient for basolateral coupled nacl entry and/or electrical gradient for cl- efflux across the luminal membrane , 4 ) the coupling of na+ entry to the presence of cl- in the mucosal solution is probably an electrical rather than a chemical cotransport process , and 5 ) the tracheal epithelium of the rabbit is not a target for aldosterone and adh .
