Fig. 2.
The concentration dependence of the reduction of the capsaicin-induced current by bupivacaine. The points and error bars represent means ± standard deviations. Only one concentration of bupivacaine was tested in each cell. The number of cells tested at each concentration is shown in parentheses. The asterisks (*) indicate significant decreases in the magnitude of the capsaicin currents compared to the corresponding control peak current, p < 0.05.
