Effect of intrathecal administration of fluorocitrate on mechanical allodynia and thermal hyperalgesia in the maintenance phase (Fig. 6, B and C).

For mechanical allodynia, von Frey test was performed as described in table 1. Thermal hyperalgesia test was evaluated as described in table 3. Data show mean ± s.e.m. (n = 7–14). **p<0.01 versus Sham-Vehicle, ##p<0.01 versus SNL-Vehicle. d, days after SNL operation; f′, days of fluorocitrate administration.
