(A) An outline of the experimental procedure for mice with CRS treatment and behavioral tests.
(B) Behavioral tests in forced swim, tail suspension, open field, and elevated plus maze (n = 7 mice per group).
(C) Time course of CRS-induced changes in pain threshold by Von Frey tests (n = 7 mice per group).
(D) The mouse left hind paw at day 3 after saline or CFA injection.
(E) CFA-induced changes in pain threshold (n = 5 mice per group).
(F) Schematic of the animal model of SNI.
(G) SNI-induced changes in pain threshold (n = 5 mice per group).
(H) Effects of ibuprofen (10 mg/kg, i.p.) or indomethacin (10 mg/kg, i.p.) on pain thresholds at day 3 after CFA treatment (n = 5 mice per group). *Preference comparison within the ibuprofen group; #preference comparison within the indomethacin group.
(I) Effects of gabapentin (10 mg/kg, i.p.) or lidocaine (10 mg/kg, i.p.) on pain thresholds at day 7 after SNI (n = 5 mice per group). *Preference comparison within the gabapentin group;, #preference comparison within the lidocaine group.
(J) Effects of ibuprofen, indomethacin, gabapentin, or lidocaine on pain thresholds of CRS 3W mice (n = 5 mice per group).
All data are presented as mean ± SEM. *p < 0.05, **p < 0.01, ***p < 0.001. ## p < 0.01, ### p < 0.001. Unpaired t test for (B); two-way repeated-measures ANOVA with Bonferroni post hoc analysis for (C), (E), and (G)–(J). See also Figure S4.
