EA, electroacupuncture; SA, sham acupuncture; NH, non-handled control; DRN, dorsal raphe nucleus; SDH, superficial dorsal horn.

Median values (range) were compared using Mann-Whitney U test. Comparisons between EA and SA group (ap = 0.02) and between SA and NH group (bp = 0.006) at DRN of brainstem, comparisons between EA and SA group (cp = 0.001) and between SA and NH group (dp < 0.001) at SDH of spinal cord, comparisons between EA and SA group (ep = 0.14) and between SA and NH group (fp = 0.01) at colonic mucosa.
