Fig. 3. Summary graph shows the mean values (± SD) for density of pinacidil-elicited sarcolemmal adenosine triphosphate–sensitive potassium channel current (IKATP) measured in anesthetic-free controls (n = 11), in the continued presence of isoflurane (ISO; n = 6), after isoflurane pretreatment and 10 min of washout (n = 12), and after isoflurane pretreatment and 30 min of washout (n = 6). * Significant at P < 0.05 versus control.
