Median values (range) were compared using Mann-Whitney U test. Comparisons between EA and SA group (ap = 0.01) and between SA and NH group (bp = 0.02) 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 = 0.005) and between SA and NH group (fp = 0.01) at colonic mucosa.
