The effect of NPPB on dilatations to K+ in pressurized arteries. (a) In arteries where stepping [K+]o from 5.88 to 10.58 mM failed to produce dilatation, dilatation to K+ was induced in the presence of 20 μM NPPB. The effect of NPPB on the ability of K+ to dilate was fully reversible on washout. The gap in the data trace indicates a period of removal of the endothelium with an air bubble. In the absence of an endothelium, the effects of NPPB were abolished. (b) Meaned data (+E, n=4±s.e.mean; −E; n=3±s.e.mean). These data are not paired, and therefore P values are for an unpaired Student's t-test. * Shows significance (P<0.05).
