the efficacy of amiloride ( 10 ( -4 ) m ) to reduce the pd was greater in cultures of cf epithelia ( -85 +/- 4.6 % , n = 7 ) than it was in cultures of normal ( -45.5 +/- 5.0 % , n = 11 ) and atopic ( -50.5 +/- 2.9 % , n = 5 ) epithelia , whereas the hyperpolarization induced by replacement of cl- in the apical bath was smaller for cf cultures ( 5.9 +/- 1.5 mv ) than it was for normal ( 9.3 +/- 0.9 mv ) and atopic ( 8.8 +/- 0.5 mv ) cultures .
