Electroacupuncture (EA) regulates the transition from acute to chronic pain induced by ψεRACK injection. Mechanical (A) and thermal (B) responses of Car/ψεRACK-injected animals to EA administration. n = 6. (C) PKCε and TRPV1 staining in the peripheral nervous system 48 h after ψεRACK injection. Scale bar, 100 μm. The quantification of the PKCε–IR positive (D) and TRPV1–IR positive (E) neurons. The quantification of the Western blot results and a representative Western blot showing PKCε (F) and TRPV1 (G) protein isolated from the DRG 48 h after ψεRACK injection. *, **Compared with the NS+PGE2 group, P < 0.05, P < 0.01; △△ compared with the ψεRACK group, P < 0.01.
