Ethnopharmacological relevanceInflammatory bowel disease (IBD) is generally associated with a set of debilitating symptoms including abdominal pain, tenesmus, diarrhea and bloody stool. The standard approaches for treating IBD, which are the application of pharmaceuticals, are often unsatisfactory. IBD patients may suffer from repeated relapses and even exacerbation after taking these medications. Thus, patients are increasingly seeking relief through the use of complementary and alternative medicines.Aim of studyTo provide scientific ground for the mode of actions of a Chinese medicinal formulation-modified ZenWu Decoction (MZWD) in ulcerative colitis.Materials and methodsC57BL6 mice were fed with 3 cycles of 2% dextran sulfate sodium (DSS) in drinking water for the induction of chronic colitis and then given MZWD at 17.47 g/kg/day. Effects of MZWD were evaluated by histopathological and biochemical assays.ResultsWhen MZWD was given, inflammatory responses namely immune-cell infiltration, elevated serum levels of pro-inflammatory cytokines and mucosal lesions were notably suppressed. Further, MZWD treatment attenuated the activation of nuclear factor-kappaB (NF-κB), the vital regulator of inflammatory cascades, while lessening the degradation of I-kappaB-alpha and reducing the activity of protease-activated receptor 2 in DSS-induced colonic tissues. Consequently, diarrhea, bloody stool and colon shortening were reduced whilst mucosal integrity was improved in MZWD-treated colitis mice.ConclusionsOur findings suggest that MZWD is a potential remedy for treating IBD, and the mechanism of its efficacy is an anti-inflammatory effect associated with the suppression of the NF-κB pathway.
