RESUMO
OBJECTIVE@#To observe the effect of moxibustion at "Zusanli" (ST 36) on distal, middle and proximal colonic mucosal injury and expression of calcitonin gene-related peptide (CGRP) positive nerve fibers of distal colonic mucosa in ulcerative colitis (UC) mice at different time points.@*METHODS@#A total of 51 C57BL/6N mice were randomized into a 7-day control group (@*RESULTS@#Mucosal injury can be observed in mice after modeling, displaying epithelial layer disappearance, abnormal crypt structure or crypt disappearance. Compared with the 7-day control group, colon length was shortened (@*CONCLUSION@#Moxibustion at "Zusanli" (ST 36) can reduce the expressions of positive nerve fibers of colonic mucosa and CGRP positive nerve fibers of distal colonic mucosa, thus, improve the colonic mucosal injury.
