a significant stimulation of short circuit current in the dose-range of 10 ( -4 ) to 10 ( -3 ) m with isoprenaline in a similar preparation was reported by cole and nagasubramanian and increase of short-circuit current and/or sodium transport in amphibian epithelia have been reported for catecholamines , and this effect may possibly be due to a decrease of the resistance to ions actively transported by the 'sodium pump ' mechanism brought about via cyclic-amp mediating the action at a cellular level .
