다국어 초록 (Multilingual Abstract)

Objectives: Inflammatory bowel disease (IBD) is a chronic relapsing inflammatory disease in the gastrointestinal tract. The sources and pathologic mechanisms of IBD are still unknown. Moreover conventional therapies for IBD are not always effective, and they often have serious side effects. The purpose of this study is to examine the effect of Moxi-tar herbal acupuncture in IBD affected mice. Methods: Mice were treated with 5 % 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) on day 1 and day 7. To assume the preemptive effect and therapeutic effect, herbal acupuncture was practiced with Moxi-tar at BL25 (Daejangsu) on day 0, day 3, and day 6. The end of day in treatment with Moxi-tar herbal acupuncture, the mortality and the inflammatory factors of the colon were measured by the various methods. Results: TNBS induced high mortality but herbal acupuncture with Moxi-tar at BL25 suppressed the mortality caused by TNBS. TNBS induced infiltration of immune cells in all layers of the colon and increased myeloperoxygenase (MPO) activity, while the treatment with Moxi-tar herbal acupuncture at BL25 suppressed the infiltration of immune cells and the increase of MPO activity caused by TNBS to normal levels. Herbal acupuncture with Moxi-tar regulated NF-κB activity, which is an important factor for the pathogenesis of chronic colitis, and reduced the expressions of TNF-α, IL-1β, and ICAM-1 in the colons of TNBS treated mice. Furthermore herbal acupuncture suppressed macro- and micro- colonic damages caused by TNBS. Conclusions: This study demonstrates that herbal acupuncture with Moxi-tar at BL25 is a potential preemptive and/or therapeutic method targeting the chronic IBD.
