- Fig. 1.
MA areas during the phentolamine (open squares) and saline (filled diamonds) infusions. Each point represents the mean areas of all 16 subjects at that time point ± SEM. The vertical line at time “0” indicates the time of capsaicin injection. Phentolamine/saline infusions were started at −10 min and completed by +10 min. *p < 0.05, areas of significantly decreased MA area during phentolamine infusion as compared with the saline infusion, Wilcoxon signed rank test.

Ongoing pain measured on a 20 cm VAS during the phentolamine (open squares) and saline (filled diamonds) infusions. Each point represents the mean ratings for all 16 subjects at that time point ± SEM.

PPH areas during the phentolamine (open squares) and saline (filled diamonds) infusions. Each point represents the mean areas of all 16 subjects at that time point ± SEM.

Skin temperatures. Mean temperature ± SEM (°C) during the course of the study for the phentolamine (open squares) and saline (filled diamonds) infusions as measured on the uninjected foot.
