Effects of DM (10 mg/kg, i.p.) and oxycodone (1 mg/kg, s.c.) on SNL-induced plasma level of pro-inflammatory cytokines: (a) IL-6, (b) IL-1β, and (c) TNF-α on day 2 (D2) and day 6 (D6) after SNL surgery. Data are presented as means ± S.E.M. (n = 7–12). One-way ANOVA and Newman-Keuls test were used to analyze the data. * P < 0.05; ** p < 0.01; *** p < 0.001 vs. Sham + saline group; # p < 0.05; ## p < 0.01; ### p < 0.001 vs. SNL + saline group
