Short circuit current in biopsies from a control patient (a) and a CRN patient (b). The rolipram-induced increase in SCC observed in CTRLs (a) is not observed in CRN-patients (b). Biopsies mounted in the MUAS chambers were exposed to: amiloride (20 μM), indomethacin (13 μM), theophylline (100 μM), bumetanide (25 μM) and ouabain (200 μM)
