  • A diverticulum is a blind pouch communicating with the gut. The term "diverticulitis" indicates inflammation of a diverticulum or diverticula, which is commonly accompanied by gross or microscopic perforation. Acute diverticuitis is a rare disorder in early childhood. Itis difficult to diagnose acute right colon diverticulitis from common causes of RLQ pain. We report a case of acute diverticulitis in the right colon in a 6-year-old girl. She complained of typical RLQ pain mimicking acute appendicitis,but was diagnosed with acute diverticulitis by CT scanning. Conservative treatment failed because of peritonitis due to perforation of an inflamed diverticulum. After the diverticulcetomy, the symptoms resolved.

  • In this study, we examined the inhibitory effects of propenone derivatives, 1,3-diphenyl-propenone (DPhP), 3-phenyl-1-thiophen-2-yl-propenone (PhT2P), 3-phenyl-1-thiophen-3-yl-propenone (PhT3P) and 1-furan-2-yl-3-phenyl-propenone (FPhP), on $TNF-{\alpha}$-induced nuclear factor (NF)-${\kappa}B$ activity and interleukin (IL)-8-induced monocyte adhesion to colon epithelial cells. 1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) that is previously reported as a $NF-{\kappa}B$ inhibitor suppressed $TNF-{\alpha}$-induced monocyte-epithelial cell adhesion in a concentration-dependent manner. The propenone derivatives, DPhP, PhT2P, PhT3P, FPhP, also inhibited $TNF-{\alpha}$-induced $NF-{\kappa}B$ activation in a similar degree to FPP-3. In a DPPH radical scavenging assay, none of the compounds showed DPPH radical scavenging activity, indicating that the inhibitory actions of the propenone derivatives on redox-sensitive $NF-{\kappa}B$ activity is not due to a simple free radical scavenging activity. In addition, the propenone derivatives also suppressed the IL-8-induced monocyte adhesion to colon epithelial cells. Furthermore, the effective concentrations of the propenone derivatives on both $NF-{\kappa}B$ activation as well as IL-8 induced monocyte-epithelial cell adhesion were 1000 times lower than 5-aminosalicylic acid (5-ASA), a clinically used drug for inflammatory bowel disease. These results suggest that the propenone derivatives may be a potential lead having a strong inhibitory activity against inflammatory cytokine-induced epithelial inflammation.

  • Dysfunction of gut immune regulation is involved in mucosal damage in inflammatory bowel disease (IBD). However, there is still no efficacious immune-regulator for the treatment of IBD. Alloferon is a novel immune-modulatory peptide that was originally isolated from infected insects. It shows anti-inflammatory effects by the regulation of cytokine production by immune cells and their activities. Therefore, we investigated the effect of alloferon in a mouse model of colitis using dextran sulfate sodium (DSS). Colitis was induced by administration of DSS in drinking water for 7 consecutive days. It was confirmed by the presence of weight loss, diarrhea, hematochezia, and colon contraction. Alloferon was injected 4 days after DSS administration. We found that alloferon improved the pathogenesis of IBD based on the reduced disease activity index (DAI) and colon contraction. Edema, epithelial erosion, and immune cell infiltration were found in mice administered DSS, but the phenomena were reduced following alloferon treatment. The plasma level of IL-6, a classical pro-inflammatory cytokine in colitis, was also decreased by alloferon. Moreover, alloferon inhibited the TNF-${\alpha}$-induced degradation and phosphorylation of $I{\kappa}B$ in Colo205 colon cancer cells. Taken together, these results show that alloferon has anti-inflammatory effects and attenuates DSS-induced colitis.

  • Crocodile farms are getting popular in Bangladesh in an economic point of view. In one of the farms, some crocodiles were found sick and three of them died between May and July in 2006. This investigation was performed to diagnose the cause of the death. Routine postmortem examination was conducted. Samples were collected in 10% neutral buffered formalin for histopathology and in falcon tube for microbiological study. Additional swabs were collected in nutrient broth. Histopathological and microbiological studies were conducted using routine procedures. In addition Giemsa, Gram and PAS stains were performed to detect the organism in tissues. Grossly, esophagus, trachea, lungs, liver, spleen, heart and kidney were congested. Intestine, rectum and colon were hemorrhagic. Clay colored material was found in colo-rectum. Purulent exudates in lungs and thick and cloudy pericardial fluid in pericardial sac were found. Histologically, multifocal granulomatous inflammation was evident in lung, liver, kidney, intestine and colon with bacterial colonies, fungal spores and hyphae. These bacteria were appeared as Gram negative. Fungal hyphae and spores were detected in liver, lungs and colon by using PAS stain. Bacteriologically, E. coli were isolated from lungs exudates, pericardial fluids and intestinal fluids. Therefore, it can be concluded that 3 crocodiles died due to E. coli septicemia concurrent with mycotic infection.

  • We had previously reported that the protective effect of taurine against indomethacin-induced gastric mucosal injury was due to its antioxidant effects, which inhibited lipid peroxidation and neutrophil activation. In this study, we examined the effect of taurine on reducing the inflammatory parameters of trintrobenzene sulfonic acid (TNBS)-induced inflammatory bowel disease (IBD) in rats. In order to induce IBD, ethanolic TNBS was given to rats intracolonically. Then they received 500 mg/kg.day of taurine orally and were sacrificed one week after IBD induction. While ulceration and inflammation of distal colon with formation of granuloma in the vehicle-treated IBD rats two days after administration of TNBS were observed, treatment with taurine ameliorated colonic damage and decreased the incidence of diarrhea and adhesion. also, colon weight as an index of tissue edema, which was mardedly increased in the IBD rats, became significantly lower after administration of TNBS were observed, treatment with taurine ameliorated colonic damage and decreased the incidence of diarrhea and adhesion. Also colon weitht as an index of tissue edema, which was markedly increased in the IBD rats, became significantly lower after taruine treatment. Myeloperoxidase (MPO) activity in the vehicle-treated IBD rats was substantially increased, compared with that of normal control. the taurine-treated animals significantly reduced MPO activity (35% lower) when compared with that of the vehicle-treated animals. Taurine treatment decreased both basal and formyl-methionyl leucyl phenylalanine-stimulated reactive oxygen generation from colonic tissue in the IBD rats. These results suggest that the administration of taurine reduce the inflammatory parameters in this IBD rat model by increasing defending capacity against oxidative damage.

  • Probiotics are microorganisms that can benefit host health when ingested in a live state, and lactic acid bacteria are the most common type. Among fungi, Saccharomyces boulardii (SB) is the only strain known to have a probiotic function with beneficial effects on colitis; however, information on other probiotic yeast strains is limited. Therefore, this study aimed to discover yeast strains expressing intestinal anti-inflammatory activities by exhibiting probiotic properties in dextran sodium sulfate (DSS)-induced colitis mice model. Nuruk (Korean traditional fermentation starter) containing various microbial strains was used as a source for yeast strains, and S. cerevisiae 28-7 (SC28-7) strain was selected with in vitro and in vivo characteristics to enable survival in the intestines. After 14 days of pretreatment with the yeast strains, DSS was co-administered for six days to induce colitis in mice. The results revealed that the disease activity index score was lowered by SC28-7 treatment compared to the DSS group, and the colon length and weight/length ratio were recovered in a pattern similar to that of the normal group. SC28-7 administration significantly reduced the secretion of pro-inflammatory cytokines in the serum and modified the mRNA expression of inflammatory cytokines (interleukin-1β, transforming growth factor-β, and interferon-γ) and proteins involved in gut barrier functions (mucin 2, mucin 3, zonula occludens-1, and occludin) in colon tissues. These results indicate that SC28-7 attenuates DSS-induced colon damage and inflammation, supporting its future use as a probiotic yeast for treating and preventing intestinal inflammatory diseases such as inflammatory bowel disease.

  • The purpose of this study was to investigate the effect of Cheonggukjang pills with aronia and blueberries on dextran sulfate sodium (DSS)-induced colitis in mice. There have been several reports that Cheonggukjang is effective for intestinal health, but the efficacy of Cheonggukjang containing fruits has not yet been reported. In this study, we showed the effect of cheonggukjang pills with blueberries and aronia (CPBA) on DSS-induced colitis in BALB/c mice. CPBA was obtained from Soonchang Moonokae foods and orally administered once a day for 2 weeks before DSS treatment. Colitis was induced in mice by feeding 5% (w/v) DSS drinking water for 7 days. The results showed that CPBA treatment significantly alleviated DSS-induced disease activity index associated with a decrease in colon length. CPBA improved DSS-induced histological changes and intestinal epithelial barrier integrity in mice colon. In addition, CPBA administration significantly reduced the levels of DSS-mediated interferon-γ and interleukin-6 in serum and tumor necrosis factor-α in colon tissue. Moreover, the gene expression of COX-2 and iNOS, which are factors involved in inflammatory signaling, was significantly reduced by CPBA treatment. These results suggest that CPBA have a protective effect against DSS-induced mice colitis and may be a candidate for colitis treatment.

  • Objectives : Ulcerative colitis (UC) is an inflammatory bowel disease, which is one of chronic gastrointestinal disorders. Orostachys japonicus (OJ) has been used as a traditional medicine for various diseases including gastric cancer, gastric ulcers and intoxication. However, the regulatory effect of OJ on intestinal inflammation has not been fully understood, yet. The aim of this study was to investigate the effect of OJ on dextran sulfate sodium (DSS)-induced colitis in mice. Methods : To ascertain the pharmacological effects of OJ, the colitis mice were induced by drinking water containing 5% DSS for 7 days. Mice were randomized into groups receiving OJ (100 mg/kg), sulfasalazine (150 mg/kg) as a positive control, or water as a negative control. We evaluated the effects of OJ on DSS-induced the clinical signs, measuring weight loss and colon length. In addition, the inhibitory effect of OJ on the tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level was determined by enzyme-linked immunosorbent assay in colitis tissue. Results : The results indicated that mice treated with DSS showed remarkable clinical signs, including weight loss, and reduced colon length. However, treatment with OJ significantly improved the weight loss and DAI as clinical symptoms. Moreover, OJ reduced the TNF-${\alpha}$ levels in DSS-treated colon tissues. Conclusions : Collectively, the findings of this study provide us with novel insights into the pharmacological actions of OJ as a potential medicine for use in the treatment of ulcerative colitis.

  • Objectives : Crohn's disease is a severe chronic inflammation that is treated mainly by immunosuppression, which often has serious side effects. There is need to develop new therapeutic methods or drugs that have few side effects in order to treat this disease. Acupuncture with Moxi-tar at Cheonchu (ST25) has anti-inflammatory properties, but the mechanism of its anti-inflammatory actions is unclear. We investigated the protective effects and speculated the mechanisms of acupuncture with Moxi-tar at ST25 on trinitrobenzene sulfonic acid (TNBS) induced colitis in mice which is a well known Crohn's disease animal model. Methods : 5 % TNBS was treated at day 1 and day 7 into rectum of mice. To investigate therapeutic effects of acupuncture with Moxi-tar at ST25, acupuncture was carried out on day 3, and day 6. For the data analysis, we observed macroscopic and microscopic findings of the colon. Weight and width of the colon, degree of damage, changes of body weight, and myeloperoxygenase (MPO) activity were checked. For analysing protein expression, we carried out immunohistochemical staining and Western blot. For analysing mRNA expression, RT-PCR was carried out. Results : TNBS induced damages on the colon of mice, while acupuncture of Moxi-tar at ST25 suppressed TNBS mediated damages similar to those on the colons of mice in the control (not treated with TNBS) group. The average body weight of TNBS treated mice (77.4%) was decreased compared with that of the control mice (105%), and acupuncture with Moxi-tar at ST25 suppressed the loss of body weight caused by TNBS (from 77.4% to 95.3%). TNBS induced infiltration of immune cells in all layers of the colon while acupuncture with Moxi-tar at ST25 suppressed infiltration of immune cells caused by TNBS. Furthermore, acupunctured with Moxi-tar at ST25 suppressed macro-, micro- colonic damages caused by TNBS. Acupunctured with Moxi-tar at ST25 dramatically improved the clinical and histopathological symptoms such as the increase in weight of the distal colon and the MPO activity in TNBS-induced colitis. Acupuncture with Moxi-tar at ST25 down-regulated the nuclear transcription factor kappa B ($NF-{\kappa}B$) activity and suppressed tumor necrosis factor-a (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-1${\beta}$), and intracellular adhesion molecule-1 (ICAM-1) expressions caused by TNBS. Conclusions : Acupuncture with Moxi-tar at ST25 helps recovery from the TNBS-induced colonic damage by down-regulation of $NF-{\kappa}B$ activity and suppressing of TNF-${\alpha}$, IL-1${\beta}$, and ICAM-1 expressions. This may be an important method for the treatment of Crohn's disease.

  • Objectives: The aim of this experimental study was to evaluate the anti-neoplastic and anti-inflammatory effects of single and mixed extracts of Ulmus davidiana (UD) and Oldenlandia diffusa (OD) on azoxymethane/dextran sodium sulfate (AOM/DSS)-induced colonic neoplasms in mice. Methods: AOM/DSS induces colitis-associated colonic neoplasms in mice. Mice were divided into seven groups: normal-no inducement and no treatment; control-colonic neoplasms with no treatment; UD-colonic neoplasms and treatment with UD; OD-colonic neoplasms and treatment with OD; UD1+OD1-colonic neoplasms and treatment with UD1 and OD1. UD1+OD2-colonic neoplasms and treatment with UD1 and OD2; UD2+OD1-colonic neoplasms and treatment with UD2 and OD1. Single and mixed preparations of UD and OD were applied to mice for six weeks. The colon length and weight and histopathologic changes of colon tissue were observed. Serum pro-inflammatory cytokines, including tumor necrosis factor-alpha ($TNF-{\alpha}$) and interleukin-6 (IL-6), were determined by enzyme-linked immunosorbent assay. The mRNA expression levels of Bax, Bcl-2, and interferon-gamma ($INF-{\gamma}$) were measured by RT-PCR. Results: The colon length was significantly increased in OD, UD1+OD2, and UD2+OD1 mice, and the colon weight was significantly decreased in OD and UD1+OD2 mice. The morphological change of colon epithelial cells was more suppressed in complex-treatment groups than in single-treatment groups. The inhibitory effect on inflammatory cell invasion was especially shown in UD1+OD2 mice. The serum level of the pro-inflammatory $TNF-{\alpha}$ was decreased in all complex-treatment groups, and the IL-6 level was decreased in UD1+OD1 mice. Single-treatment groups had an increase in the mRNA expression of the pro-apoptosis regulator Bax, and UD2+OD1 decreased the mRNA expression of the anti-apoptosis regulator Bcl-2. The mRNA expression of $INF-{\gamma}$ associated with inflammation was decreased in OD and UD1+OD2 mice. Conclusions: This study suggests that single and mixed extracts of Ulmus davidiana and Oldenlandia diffusa have anti-neoplastic and anti-inflammatory effects on AOM/DSS-induced colonic neoplasms in mice. Therefore, we conclude that UD, OD, and a mixture of UD and OD are potential therapeutic agents for colitis-associated colonic neoplasms.
