Figure 7. Comparison of the effects of desflurane at a [Ca sup ++]^oof 1 mM in control conditions, after adrenoceptor blockade, or after pretreatment with reserpine, on isometric active force normalized per cross-sectional area (AF). Data are mean +/- SD (n = 10 in each group). *P < 0.05 versus control values. Probability values refer to between-groups comparisons. NS = not significant.
