Spinal Serotonergic and Opioid Receptors Are Involved in Electroacupuncture-Induced Antinociception at Different Frequencies on ZuSanLi (ST 36) Acupoint

Figure 4

Pretreatment with opioid antagonists influences EAc-induced antinociception in different frequencies on the 1st (a, b, c), 3rd (d, e, f), and 7th (g, h, i) days after intrathecal cannulation. (a), (d), (g): 1 mA, 2 Hz EAc; (b), (e), (h): 1 mA, 10 Hz EAc; (c), (f), (i): 1 mA, 100 Hz EAc; : initiation point of EAc except sham group. ○: sham group. : ACSF: artificial CSF. ▲: naloxone (0.05 μg/10 μL, i.t.). ■: naltrindole (0.05 μg/10 μL, i.t.). Data are shown as mean ± S.E. , , and compared to the ACSF group ( ).
