Crohn disease (CD) is rare, but the incidence of CD has been increasing over the past ten years. We found two cases of CD, associated with myelodysplastic syndrome (MDS), for the first time in children. In the first patient, MDS was diagnosed at three years of age and CD developed later at eight years of age. The patient presented with recurrent abdominal pain, diarrhea, bloody stools and failure to thrive. Colonoscopy revealed cobble stone like mucosa and mass like lesions with superficial ulceration and inflammatory exudates, observed from the cecum to ascending colon. Ileo-cecal biopsy samples showed ulcers with skipped areas and lymphoid infiltrations. The patient was started on treatment with mesalazine and deflazacort, and symptoms remitted. In the second patient, MDS was diagnosed at nine years of age and CD developed at 13 years of age. This patient has recurrent hematochezia, abdominal pain, vomiting and fever. Colonoscopy revealed a large, deep indurative ulceration on the cecal side of the ileo-cecal valve. Ileocecectomy was done, and histology revealed ulceration with transmural inflammation and lymphoid aggregates. Symptoms improved after ileocecectomy.

Intractable ulcerating enterocolitis is an uncommon inflammatory bowel disease syndrome of neonatal onset first described in 1991. Intractable ulcerating enterocolitis usually presents in the neonate with a mouth ulceration and the subsequent development of perianal disease and colitis. In this case report, an infant, 18 days from birth, with ulcerative lesion on hard palate for systemic differential diagnosis about oral lesion is referred from the department depiatrics. At that time, there is no abnormality, except oral lesion-like Aphthous ulcer. The patient was discharged from pediatrics, but returned to the hospital 3weeks later with blood diarrhea. As a result of endoscopy, there were large ulcerating lesions and the patient was diagnosed intractable ulcerating enterocolitis. Early recognition of Intractable ulcerating enterocolitis appears to be beneficial because colectomy, as opposed to immunosuppression, appears to be effective in controlling disease symptoms and progression. Most of the infants who were affected intractable ulcerating enterocolitis were normal at birth and oral manifestation appeared earlier than others. So, it is very meaningful for dentists to know about Intractable ulcerating enterocolitis.

To observe the clinical course and intestinal histopathology in heavy infection of Fibricola seoulensis, an experimental study was performed in mice. Clinical, experimental infection with 1, 000 metacercariae. On the 11th day after infection, the mice began to die and all of the infected mice were dead by the 16th day. The infected mice showed gradual weight loss. Occult blood was detected after the 10th day. Diarrhea accurred after the 9th day and was recognized in all of the infected mice on the 12th day. Hemoglobin and mean corpuscular hemoglobin decreased significantily after the 12th day, and mean corpuscular hemoglobin concentration decreased in all infected mice. The histopathological changes were more marked in the duodenum than in the jejunum or ileum. Major changes were villous atrophy and crypt hyperplasia, with decreased villus/crypt ratio, inflammatory cell infiltration and stromal edema. The present results suggest that the cause of death of mice heavily infected with F. seoulensis should be malnutrition and severe fluid loss due to malabsorption, together with intestinal bleeding.

The object of this study was to obtain acute information (single oral dose toxicity) of Taraxaci Herba (Dried total parts of Taraxacum platycarpum. H.Dahlstedt (Compositae)), has been traditionally used in Korean medicine for treating various inflammatory diseases. In order to observe the 50% lethal dose (LD 50), approximate lethal dosage (ALD) and target organs, test articles were once orally administered to female and male ICR mice at dose levels of 2,000, 1,000, 500 mg/kg according to the recommendation of Korea Food and Drug Administration Guidelines. The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after single oral treatment of Taraxaci Herba aqueous extracts according to KFDA Guidelines with organ weights and histopathological observations of 12 types of principle organs. After single oral treatment of Taraxaci Herba aqueous extracts, we could not find any mortality and toxicological evidences up to 2,000 mg/kg treated group, the limited dosages in rodents at body and organ weights, clinical signs, gross and histopathological observations. Except for slight soft feces, which were detected in male mice treated with 2,000 mg/kg of Taraxaci Herba aqueous extracts at 1 day after end of treatment. The results obtained in this study suggest that the LD 50 and ALD of Taraxaci Herba aqueous extracts in both female and male mice after single oral treatment were considered as over 2,000 mg/kg because no mortalities were detected up to 2000 mg/kg that was the highest dose recommended by KFDA and OECD. However, it also observed that the possibility of digestive disorders, like diarrhea when administered over 2,000 mg/kg of Taraxaci Herba aqueous extracts in the present study, but these possibilities of digestive disorders can be disregard in clinical use because they ate transient in the highest dosages male only.

Objectives : Ecklonia cava is brown alga(Laminariaceae) which grows is sea, it has antioxidant, diarrhea and anticoagulant effect. In this study, the effect of ethanol extract of Ecklonia cava (EC) on peptidoglycan(PGN) -induced NO production in RAW 264.7 cells was investigated. Methods : In the present study, IL-6 production was measured using the enzyme-linked immunosorbent assay(ELISA), prostaglandin $\E_2$($\PGE_2$) production was measured using the EIA kit, and inducible NO synthase(iNOS), cyclooxygenase-2(COX-2), and mitogen-activated protein kinase(MAPK) activation, as determined by western blot analysis and reverse transcription -polymerase chain reaction(RT-PCR). Results : EC inhibited PGN-induced NO and IL-6 production. Consistent with these observations, the protein expression of iNOS and COX-2 were inhibited by EC. Moreover, EC suppressed the phosphorylation of extracellular signal-regulated kinase(ERK) 1/2 in PGN-induced RAW 264.7. Conclusions : These results suggest that EC has inhibitory effects on PGN-induced $\PGE_2$, NO, and IL-6 production, as well as the expressions of iNOS and COX-2 in the murine macrophage. These inhibitory effects occur through blockades on the MAPKs phosphorylation.

Background/Aims A Subset of patients with irritable bowel syndrome (IBS) may have mild inflammation due to immune activation. Toll-like receptors (TLRs) and cytokines may cause intestinal inflammation. We studied their expression in relation to gut microbiota. Methods Expression of TLRs and cytokines was assessed in 47 IBS patients (Rome III) and 25 controls using quantitative real-time polymerase chain reaction. Immunohistochemistry was further performed to confirm the expression of TLR-4 and TLR-5. Results Of 47 patients with IBS, 20 had constipation (IBS-C), 20 diarrhea (IBS-D), and 7 unclassified (IBS-U). The mRNA levels of TLR-4 and TLR-5 were up-regulated in IBS patients than controls (P = 0.013 and P < 0.001, respectively). Expression of TLR-4 and TLR-5 at protein level was 4.2-folds and 6.6-folds higher in IBS-D than controls. The mRNA levels of IL-6 (P = 0.003), C-X-C motif chemokine ligand 11 (CXCL-11) (P < 0.001) and C-X-C motif chemokine receptor 3 (CXCR-3) (P < 0.001) were higher among IBS patients than controls. Expression of IL-6 (P = 0.002), CXCL-11 (P < 0.001), and CXCR-3 (P < 0.001) were up-regulated and IL-10 (P = 0.012) was down-regulated in IBS-D patients than controls. Positive correlation was seen between TLR-4 and IL-6 (P = 0.043), CXCR-3, and CXCL-11 (P = 0.047), and IL-6 and CXCR-3 (P = 0.003). Stool frequency per week showed positive correlation with mRNA levels of TLR-4 (P = 0.016) and CXCR-3 (P = 0.005), but inversely correlated with IL-10 (P = 0.002). Copy number of Lactobacillus (P = 0.045) and Bifidobacterium (P = 0.011) showed correlation with IL-10 in IBS-C, while Gram-positive (P = 0.031) and Gram-negative bacteria (P = 0.010) showed correlation with CXCL-11 in IBS-D patients. Conclusions Altered immune activation in response to dysbiotic microbiota may promote intestinal inflammation in a subset of patients with IBS.

Norovirus is the most common cause of acute gastroenteritis. Its pathogenesis is poorly understood owing to the difficulty of establishing viral infection in animal models. Here, post-weaning gnotobiotic pigs were infected with human norovirus genogroup II genotype 4 (HuNoV GII.4) to investigate the pathogenesis and replication of the virus. Three groups of four pigs were infected with $1{\times}10^5$, $1{\times}10^6$, or $1{\times}10^7$ genomic equivalent (GE) copies of HuNoV GII.4. Four pigs were used as negative controls. Blood and rectal swab samples were collected after viral infection, and gross legions were examined after necropsy. Diarrhea was induced in 25% and 75% of pigs infected with $1{\times}10^6$ and $1{\times}10^7$ GE copies, respectively. Viral shedding was detected in 50%, 75%, and 50% of pigs infected with $1{\times}10^5$, $1{\times}10^6$, and $1{\times}10^7$ GE copies, respectively. Viremia was detected in 25% of pigs infected with either $1{\times}10^6$ or $1{\times}10^7$ GE copies. When gross lesions of gastroenteritis were investigated, the ileum walls of the infected pigs were thinner than those of the controls. Villi atrophy and inflammatory cell infiltration were identified in the ileum of each infected pig. Viral capsid was identified in the jejunum, ileum, colon, spleen, and mesenteric lymph node. Virus replication was newly verified in the spleen and mesenteric lymph nodes by detection of negative-sense viral RNA. In conclusion, HuNoV GII.4 could induce acute gastroenteritis and replicate in the extra-intestinal lymphoid tissues in post-weaning gnotobiotic pigs. Therefore, such pigs would be a suitable animal model for studying the pathogenesis and replication of HuNoV.

Probiotics have emerged as a potential treatment modality for numerous gastrointestinal disorders, including IBD. However, few probiotics have undergone appropriate preclinical screening in vivo. Kefir is considered a probiotic, benefiting the host through its effects in the intestinal tract. Despite numerous studies examining the action of probiotics on the host organism, few have analyzed the effects on intestinal environment. We assessed the protective effect of kefir for three weeks before inducing colitis with 2% dextran sodium sulfate for five days. The DSS loads were similar in all DSS treatment group. The results of the experiment are as follows. Food intake and FER of experimental groups were not significantly different each other, but water consumption tended to be higher in all DSS treatment groups as compared with the normal control. And visual inspection of feces revealed mild diarrhea in rat given 2% DSS. The anti-inflammatory activity of kefir was determined by myeloperoxidase activity during the DSS treatment, and there was no significant difference in any group. The levels of thiobarbituric acid reactive substances (TBARS) as a colonic lipid peroxidation were significantly lower in the kefir intake groups than in rats treated with 2% DSS alone. The DNA % in tail and tail moment values as a DNA damage level of the blood lymphocytes in kefir intake groups tended to be lower than 2% DSS treatment alone, especially tail lengths were significantly diminished. According to the colonic histopathological assay, there were a severe inflammation of lamina propria and submucosa and mild edema in mucosa and sub mucosa in DSS alone treated group. We found a slight regenerative change in kefir treatment groups. In our experiments, this means that ulcerative colitis related to oxidative injury might be prevented by kefir as a probiotic. Further studies of the potential benefits of kefir as a probiotic in inflammatory condition are encouraged.
