Effect of fasudil on reactivity of PAs to pressure and vasoactive agents. (a) Graph showing active inner diameters of PAs in response to pressure. Fasudil treatment did not affect inner diameter of PAs at any pressure studied. (b) Graph showing percent tone of PAs at different pressures. Fasudil had no significant effect on percent tone of PAs. Graphs showing (c) percent constriction to U-46619 and (d) percent reactivity to diltiazem. Fasudil had no effect on reactivity to U46619 or diltiazem.
