(a) Relaxing concentration-response curves of CF-AECal (■) on rat tracheal rings pretreated with L-NAME (▼), indomethacin (), methylene blue (○), and propranolol (⚫) and precontracted with acetylcholine (10 μM). (b) Relaxing concentration-response curves of CF-AECal (□) on rat tracheal rings pretreated with glibenclamide (⚫) and tetraethylammonium (▲) and contracted with acetylcholine (10−5 M). Data are expressed as the mean ± S.E.M. of six experiments.
