ABSTRACT
Ulcerative colitis is a chronic nonspecific inflammatory disease of unknown cause. The aim of this study was to evaluate the anti-inflammatory effect of tauroursodeoxycholate in 2, 4, 6-trinitrobenzenesulfonic acid-induced experimental colitis in mice. After the induction of colitis for 24h, the mice were administrated orally with tauroursodeoxycholate (20, 40 and 60mg/kg) and sulfasalazine (500mg/kg) by gavage for 7 consecutive days. The inhibition effects were evaluated by the body of weight change, survival rate, macroscopical and histological evaluations. Besides, myeloperoxidase (MPO) activity, interleukin (IL)-1ß, interferon (IFN)-γ and tumour necrosis factor-α (TNF-α) in colon tissue were also determined by enzyme-linked immunosorbent assay. Treatment with different doses of tauroursodeoxycholate (20, 40 and 60mg/kg) significantly improved the body weight change, decreased the macroscopic and histopathological scores. Compared with the model group, the accumulation of MPO activity, the colonic tissue levels of IL-1ß, IFN-γ and TNF-α were significantly reduced in the tauroursodeoxycholate treated groups. Moreover, tauroursodeoxycholate assuaged the symptoms of colitis. These results suggested that tauroursodeoxycholate has an anti-inflammatory effect in TNBS-induced ulcerative colitis in mice.
