Effect of MEK inhibitor (U0126) on PWTs to mechanical stimuli in CFA-injected rats with EA stimulation. PWTs were measured at pre-injection, 5, 6, 25 and 49 h after CFA injection. Values represent mean ± SEM; n = 10 per group for each time point. ○○P < 0.01 versus DMSO group at the corresponding time point. △△P < 0.01 versus EA plus DMSO group at the corresponding time point.
