  • Dextran sodium sulfate (DSS) is a widely used chemical model for inflammatory bowel disease (IBD). It is thought that imbalances in the T helper (Th) cell subsets contribute to IBD. Recent studies suggest that the acute DSS-colitis model is polarized toward a Th1/Th17 profile based on RT-PCR analysis of colonic tissues. In the current study we determined whether colonic Th cells from DSS-colitis mice were skewed toward the Th17 profile. Mice were treated with 5% DSS for 7 days and colonic T cells isolated and examined for production of IFN-${\gamma}$ (Th1 cell), IL-4 (Th2 cell) and IL-17 (Th17 cell) by intracellular flow cytometry. We found that the percentage of colonic Th17 cells were similar to non-treated controls but the percentage of Th1 cells were elevated in DSS-colitis mice. These results suggest that in the acute DSS-colitis model the colonic Th cells exhibit a Th1 profile and not a Th17 profile.

  • Inflammatory bowel disease and alimentary lymphoma are common gastrointestinal disorder in cats. More recently, ultrasonographic features associated with feline alimentary lymphoma has been recognized as a diffuse thickening of muscular layer of small intestine. We investigated correlation between thickening of muscular layer of small intestine and such disease. We found a significantly increased thickness of the muscular layer of small intestine in cats with lymphoma or IBD compared with healthy cats. When a muscularis to submucosa ratio > 1 and regional lymphadenopathy were found during ultrasonography on cats with gastrointestinal signs, full-thickness biopsy could be recommended to make sure presence confirmation of inflammatory bowel disease or alimentary lymphoma.

  • The inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn disease are characterized by chronic inflammation throughout the gastrointestinal tract. The prevalence of IBD has been increasing worldwide, and has sometimes led to irreversible impairment of gastrointestinal structure and functions. In the present study, we identified a new sulfoquinovosylmonoacylglycerols (SQMG) (1) together with two known SQMGs (2 and 3) regulating intestinal inflammation from the brown alga Turbinaria ornata. The anti-inflammatory properties of two bioactive SQMGs, 1 and 2 were evaluated using an in vitro co-culture system consisting of human epithelial Caco-2 cells and PMA (phorbol 12-myristate 12-acetate)-differentiated THP-1 macrophages. Treatment with 1 or 2 inhibited the production nitric oxide and prostaglandin E2 induced by lipopolysaccharide and interferon γ challenge. The expressions of inducible nitric oxide synthase and cyclooxygenase 2 were markedly down-regulated in response to inhibition of nuclear factor κB translocation to nucleus. These findings suggest the potential use of the brown alga T. ornata and its biologically active metabolites SQMGs as pharmaceutical adjuvants in the treatment of inflammation-related diseases, including IBD.

  • It is known that lactic-acid bacteria (LAB) helps keeping the intestine healthy and to enhance its immunologic competence. In addition, it is known to control the composition of the enterobacteria and the intestinal inflammatory reaction by inducing immunological enhancement. This study was performed, in a mouse model, to test the treatment and preventive effects of LAB of inflammatory bowel disease (IBD), which was induced by a blend of LAB-administering trinitrobenzene sulfonic acid (TNBS). To obtain the animal model of IBD, 2% TNBS was rectally administered once to a five-week-old male Balbc/J mouse. A probiotic combination was administered to the prevention group five times a week for eight weeks before the inducement of enteritis, and the mixture was administered to the treatment group five times a week, after the administration of TNBS. The changes in the levels of the cytokines of the lymph nodes and the tissue of the large intestine were observed, both with the naked eye and with a microscope. The observation showed that the levels of inflammatory cells, infiltration, and necrosis were much lower in the LAB-administered groups than in that of the control group. In addition, the inflammatory cytokines (e.g., TNF-${\alpha}$, IL-17A) decreased in the lymph nodes and the tissues of the large intestine. The results indicated that the administration of the combination to the animal model suppressed the inflammatory cytokines in the large intestine and in the lymph nodes, which in turn suppressed the progression of colitis.

  • 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 sup-pressed 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 $NF-{\kappa}B$ activity, which is an important factor for the pathogenesis of chronic colitis, and reduced the expressions of $TNF-{\alpha}$, $IL-1{\beta}$, 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 isa potential preemptive and/or therapeutic method targeting the chronic IBD.

  • Purpose: The aim of this study was to evaluate the nutrient content consumed by children and adolescents on home-prepared versus chef-prepared specific carbohydrate diets (SCD) as therapy for inflammatory bowel disease (IBD). Methods: Dietary intake of two cohorts with active IBD initiating the SCD over 12 weeks was assessed. The home-prepared cohort received detailed guidance from dietitians on implementation of the SCD. The chef in the other cohort was knowledgeable in the SCD and prepared meals from a fixed set of recipes. Data from 3-day diet diaries at 4 different time points were collected. US Recommended Daily Allowances (RDA) were calculated for macronutrients, vitamins, and minerals. Results: Eight participants on the homemade SCD and 5 participants on the chef-prepared SCD were included in analysis. Mean % RDA for energy intake was 115% and 87% for homemade and chef-prepared groups (p<0.01). Mean % RDA for protein intake was 337% for homemade SCD and 216% for chef-prepared SCD (p<0.01). The homemade SCD group had higher mean % RDA values for vitamin A and iron, while the chef-prepared SCD group had higher intake of vitamins B1, B2, D, phosphorus and zinc (p<0.01 for all). Conclusion: The SCD implemented homemade versus chef-prepared can result in significantly different intake of nutrients and this may influence efficacy of this dietary therapy. Meal preparation dynamics and the motivation of families who pursue dietary treatment may play an important role on the foods consumed and the outcomes on dietary therapy with the SCD.

  • Inflammatory Bowel Disease is caused by an acute or chronic dysfunction of the mucosal inflammatory system in the intestinal tract. In line with the results of our previous study, wherein we found that the PKCα-LSD1-NF-κB signaling plays a critical role in the prolonged activation of the inflammatory response, we aimed to investigate the effect of signaling on colitis in the present study. Lsd1 S112A knock-in (Lsd1SA/SA) mice, harboring a deficiency in phosphorylation by PKCα, exhibited less severe colitis symptoms and a relatively intact colonic epithelial lining in dextran sulfate sodium (DSS)-induced colitis models. Additionally, a reduction in pro-inflammatory gene expression and immune cell recruitment into damaged colon tissues in Lsd1SA/SA mice was observed upon DSS administration. Furthermore, LSD1 inhibition alleviated colitis symptoms and reduced colonic inflammatory responses. Both LSD1 phosphorylation and its activity jointly play a role in the progression of DSS-induced colitis. Therefore, the inhibition of LSD1 activity could potentially protect against the colonic inflammatory response.

  • Many modern people are exposed to chronic inflammatory diseases, such as inflammatory bowel disease (IBD), atopic dermatitis and immune disorder. Among those chronic diseases, the incidence ratio of IBD has been increased. IBD, including Crohn's disease and ulcerative colitis (UC), is known to cause abnormal inflammation in intestinal tissue. UC is accompanied by abdominal pain, bloody stool and diarrhea. Many therapeutic agents, such as sulfasalazine, corticosteroids, immunosuppressive agents, have been used for treating UC. However, those agents have side-effects and temporary effects on UC. The aim of this study was to investigate the effect of herbal medicine on UC and relationship between UC and intestinal bacteria according characteristic of herbal medicine. To determine the effect of herbal medicine on UC, various herbal medicine were chosen within oriental medicine category such as cheongyeol and onyeol medicine. In this study, we found carthami fructus, included in cheongyeol medicine, had stronger effect than onyeol medicine. Also, we determined influence of carthami fructus against lactic acid bacteria. Catthami fructus and lingon berry extracts affected the composition of mice intestinal bacteria in mice fecal. The symptoms of UC could be regulate by using herbal medicine, according to characteristic of herbal medicine. Also, herbal medicine might be change body condition to healthy by controlling intestinal bacteria composition. Herbal medicine characteristic could be a therapeutic agent by revealing relationship between intestinal bacteria and UC.

  • Signal transducer and activator of transcription 3 (STAT3) is associated with various human diseases, such as cancer, auto-immune disease, and intestinal inflammation. The limited and inadequate effect of standard approaches for treating inflammatory bowel disease (IBD) has prompted to develop alternative anti-colitis agents through inhibition of STAT3. Here, we show that gallic acid (GA), a 3,4,5-trihydroxybenzoic acid, markedly reduced phosphorylation of STAT3. Among the derivatives of benzoic acids, GA showed significant inhibition on STAT3 phosphorylation. In addition, GA ameliorated the dextran sodium sulfate (DSS)-induced acute colitis as determined by the measurement of symptomatic and histological indices. The suppression of DSS-induced acute colitis by GA treatment may be related to the regulation of cytokines and growth factors. Furthermore, GA inhibited phosphorylation of STAT3 in the colon tissue of DSS-treated mice. These findings may be useful in comprehending the molecular action of GA on STAT3 phosphorylation and provide novel insights into the potential application of GA in the treatment of STAT3-related inflammatory disease, such as IBD.

  • Purpose : There are two modalities, those are small bowel series(SBS) and abdominal pelvic computed tomography(CT), for diagnosis of small bowel disease. The aim of this study is to lend radiological technologists who are doing the two modalities assistance in the understanding characteristic of disease by comparing the two results. Meterials and method : 284 patients were examined the two SBS and abdominal pelvic CT together from 1999 to 2003. 250 ml $BaSO_4$ suspension 40 w/v% and 600ml carboxy methyl cellulose 0.5 w/v% were used for SBS. Abdominal Pelvic CT was examined in one hour before taking 450 ml $BaSO_4$ suspension 1.5 w/v%. The CT scan was done in 72 sec after 150 ml contrast media injection. the used protocol was helical mode 5:5 mm pitch 1.375:1, speed 27.50, exposure 120 kv, 240 mA, tube rotation time 0.5 sec. the statistic analysis was conducted with statistical program SPSS 10 version with frequency and crossing analysis. P-value less than 0.05 were considered significant. Results : In the results of SBS, normal findings were 131 patients(46.1%), inflammatory bowel disease(IBD) 64(22.9%), ischemia+ileocolitis+vasculitis 22(7.7%), Obstruction+stricture 21(7.7%) and Others 45(15.9%). In the results of abdominal pelvic CT, normal findings were 103 patients(36.3%), inflammatory bowel disease 65(22.9%), wall thickening+lymphadenopathy 42(14.8%), Fluid collection 17(6%), and Others 57case(20%). The same results of the two were 130patients(45.8%). 30patients(10.6%) of normal finding in SBS were diagnosed as wall thickening+lymphadenopathy and IBD in CT, and 15patients(5.3%) of normal finding in CT were diagnosed as ischemia+ileocolitis+vasculitis, mass and IBD in SBS(p<0.05). Transit time delay was diagnosed in 10patients(3.5%) on only SBS, wall thickening+lymphadenopathy was diagnosed in 20patients(7%) in only CT(p<0.05). Conclusion : We think that proper examination method will be selected in the small bowel disease, if we understand the characteristics of the disease and method.
