Fig. 1From: Short-term anesthesia inhibits formalin-induced extracellular signal-regulated kinase (ERK) activation in the rostral anterior cingulate cortex but not in the spinal cordShort general anesthesia does not modulate formalin induced spinal PERK expression. a Typical PERK expression in the ipsilateral superficial dorsal horn for each treatment group. Scale bar 50 µm. b PERK counts. LSD post hoc, **P < 0.01, Formalin vs. Sham groups. Data presented as mean ± SEM (n = 3 each group).Back to article page
