... were measured. External amiloride reduced I cut and G cut at half-maximal concentrations of 0.7 and 0.6 μmol l –1 , respectively. Amiloride-induced current-noise analysis gave similar results to those observed with split gill lamellae. Ion-substitution experiments with isolated cuticles further support...

... force. Amiloride-induced current-noise analysis revealed that stimulation of I Na was accompanied by an increase in the apparent number of open apical Na + channels at a slightly reduced single-channel current. In addition to the electrophysiological experiments, whole gills were perfused...
