COX-2 and inflammatory cytokine induction in the DRG following PGI. (A) COX-2 mRNA levels measured in L3–L5 DRGs, 3 days after PGI and compared to a sham operation or hindpaw inflammation. (B) Hindpaw inflammation but not PGI-induced COX-2 mRNA in the dorsal horn (DH). (C) Increase in IL-1β mRNA in L4 DRG of PGI treated animals. (D) Increase in TNF-α mRNA in L4 DRG of PGI treated animals. *p < 0.05 vs. sham control. **p < 0.01 vs. sham control. N = 4 for each group of animals.
