Neural inhibition of venous vasoconstriction. a PBZ did not block venous constriction induced by 20 V stimulation, but it reduced constriction induced by KCl (p = 0.02). b Although guanethidine reduced constriction induced by 20 V stimulation and by KCl, the differences were not significant. c PBZ did not affect vasoconstriction induced by 150 V stimulation. d Guanethidine did not affect constriction induced by 150 V stimulation. Horizontal lines indicate the maximum constriction achieved with potassium chloride (black). Statistical comparisons were performed using the one-way ANOVA and the Tukey-Kramer multi-comparison test; N = 5 for guanethidine, N = 6 for PBZ and N = 7 for control
