The effect of AMG9810 and chelerythrine on established thermal hyperalgesia (TH) in acidic saline injected TIIP (AS-TIIP) rats. Effects of AMG9810 (a TRPV1 antagonist) and chelerythrine (a PKC inhibitor) in established TH were evaluated at day 3 post-surgery and pH 4.0 injection. (A) Intraplantar injection of AMG9810 (3 and 10 nmol) was effective in reversing the established TH in a dose dependent manner (n = 4, 4, 5 in each group). The analgesic effect of AMG9810 was significant at 30 min and 1 h post-injection (*p < 0.05, **p < 0.01 and ***p < 0.001 vs vehicle). (B) Intraplantar injection of chelerythrine (10 and 30 nmol) dose dependently reversed TH at the 1 and 3 h time point after injection in established TH rats (n = 4, 6, 6 in each group, ***p < 0.001 vs vehicle).
