Fig. 6. Influence of the CaMKII inhibitor KN-93 on the anesthetic-induced relaxation. Force expressed as a percentage of the control in mean± SD (n = 3–9); [KN-93] (μm) = concentrations of CaMKII inhibitor KN-93 in μm; one of the anesthetic concentrations was present except at 0/0 (time control) in which neither anesthetic nor KN-93 was present; *P < 0.05 compared with that of the time control (0/0); #P < 0.05 compared with that of the anesthetic in the absence of KN-93 (0 μm).
