Distinct actions of post-treatment of DHAand DHA-derived SPMs on fPOP. Impact of post-surgical treatment with DHA (500 μg, i.t.) or DHA-derived SPMs RvD1, MaR1, NPD1, and RvD5 (500 ng, 10 μl, i.t.), given 2 weeks after bone fracture surgery (indicated by blue arrows) on mechanical allodynia, assessed by measurements of paw withdrawal threshold (A) and paw withdrawal frequency (B) in the von Frey test, as well as of cold allodynia, assessed by cold response scoring in the acetone test (C). Note that post-treatment of DHA has no effects on fPOP. P < 0.05 vs. vehicle (10% ethanol), two-way ANOVA followed by Bonferroni test, n = 5–7 mice/group. Data are presented as mean ± SEM.
