ABSTRACT
AIM To investigate the effect of ke tamine on ATP-sensitive K + currents (I K ATP ) in single airway smooth muscle (ASM) cells of asthmatic rat. METHODS Single ASM cells of asthmatic rat were isolated with enzymatic dissociation technique. Effect of ketamine on I K ATP in single ASM cells was studied using the whole-cell configu ration of patch clamp technique. RESULTS Ketamine opened the ATP -sensitive K + channel (K ATP channel) in a dose-dependent manner. When the concentrations of ketamine were 1?10 -7 ,1?10 -6 ,1?10 -5 and 1?10 -4 mol?L -1 , the amplitude values of I K ATP were increased to 63 86?19 33 pA/pF(n=8,P
