OBJECTIVE: To observe the effect of moxibustion and acupoint catgut embedding (ACE) at "Tianshu"(ST25) "Dachangshu"(BL25) and "Shangjuxu"(ST37) on changes of body mass, stool property, histopathological conditions and expression levels of interleukin 6 (IL-6) in colonic mucosa of ulcerative colitis (UC) rats, so as to reveal its anti-inflammatory mechanisms underlying improvement of UC. METHODS: SD rats were randomized into normal, model, moxibustion, ACE and moxibustionï¼ACE groups (nï¼6 in each group). The UC model was established by enema of trinitro-benzene-sulfonic acid and ethanol. Moxibustion was applied to bilateral ST25, BL25 and ST37 for 10 min, once daily for 14 days, and ACE applied to the same 3 acupoints, once a week for two weeks. After the treatment, the rats' general conditions were observed, and the severity of UC was assessed by using disease activity index (DAI) score. Colonic mucosal pathological changes were observed under microscope after hematoxylin eosin (H.E.) stain, and the expression levels of IL-6 in the colonic mucosa tissue detected by using immunohistochemical stain and Western blot, respectively. RESULTS: After modeling, the DAI score, and expression level of colonic IL-6 protein detected by immunohistochemistry and Western blot were obviously increased in the model group relevant to the normal group (P<0.01). Following the intervention, the increase of DAI score and IL-6 expression were reversed in moxibustion, ACE and moxibustionï¼ACE groups (P<0.01, P<0.05). The therapeutic effects of moxibustionï¼ACE were considerably superior to those of simple ACE and simple moxibustion in down-regulating the levels of DAI score and IL-6 expression (P<0.01). Hï¼E. staining showed severe defect of the colonic mucosal epithelium with infiltration of a large number of inflammatory cells in the model group, which was milder in moxibustion, ACE and moxibustionï¼ACE groups. CONCLUSION: Moxibustion combined with ACE is able to improve the inflammatory injury of colonic mucosa in UC rats, which may be related with its effect in suppressing the expression of colonic IL-6; and the efficacy of moxibustionï¼ACE is apparently superior to that of moxibustion and ACE alone.
