Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract that affects the large bowel. Its etiology remains controversial. However, an infectious or immunologic origin is considered the primary cause. The onset of UC is typically slow and insidious, but some patients may present acutely with symptoms mimicking infectious colitis. We report a case of ulcerative colitis mimicking acute hemorrhagic colitis at initial presentation. A 60-year-old man was referred to Yeungnam University Hospital for bloody diarrhea and abdominal pain. Sigmoidoscopy revealed mildly edematous mucosa in the rectum and hyperemic mucosa with petechiae in the sigmoid colon. The patient was treated with antibiotics for several days, and his symptoms improved. However, after one month, his bloody diarrhea relapsed. Follow-up sigmoidoscopy revealed mucosal friability in the rectum and sigmoid colon. He was diagnosed with ulcerative colitis, and his symptoms were improved with mesalazine and a steroid enema.

Nowadays, Klebsiella oxytoca is described as a causative organism for antibiotic-associated hemorrhagic colitis (AAHC). Here we report two cases of pediatric AAHC, from which K. oxytoca was cultured after starting amoxicillin-clavulanate or amoxicillin treatment. The patients developed severe abdominal pain and a large amount of bloody diarrhea. K. oxytoca was obtained in intestinal fluid culture of a boy through the colonoscopy. On the other hand, colonic tissue culture and intestinal fluid culture were negative of the other patient. K. oxytoca was detected in stool culture when he was admitted. These cases showed characteristic endoscopic findings of segmental hemorrhagic colitis, and both boys recovered spontaneously within 2-3 days after they stopped taking the antibiotics. Therefore, in children who develop relatively large amount of bloody diarrhea after antibiotic treatment, we should consider AAHC caused by K. oxytoca.

Objectives: This study was to investigate the anti-oxidative and anti-inflammatory effect of Psoralea corylifolia water extract (PE) on ulcerative colitis which was induced by dextran sulfate sodium (DSS) in mice. Methods: Ulcerative colitis was induced by DSS in male BALB/c mice. The mice were divided into 3 groups. The control group (Ctrl) was not induced ulcerative colitis. The pathological group (CE) was induced the colitis. The experimental group (PT) was administered PE after inducing the colitis. The effects of the PE on ulcerative colitis were evaluated by morphological change in the colon tissue and cells, substance P production, activity of tumor necrosis factor $(TNF)-{\alpha}$ and nuclear factor $(NF)-{\kappa}B$, cyclooxygenase (COX)-2 production, and anti-oxidative activity. Results: In the PT group, PE alleviated hemorrhagic erosion in colon mucosa and infiltration of inflammatory cells in lamina propria mucosae. In the colon of the PT group, COX-2 production was inhibited via regulating the activity of $TNF-{\alpha}$ and $NF-{\kappa}B$ p65. PE also had an anti-oxidative effect via activating nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Conclusions: In this study, we found the utility of treatment with PE and the potential of developing a medicine for ulcerative colitis by applying our results. Further investigations for the anti-inflammatory mechanism of PE may be needed.

Objectives: Dojeckjiyu-tang has been used to treat Hwaseol & Jeokri. The object of this study is examination of the treatment effect of Dojeckjiyu-tang for ulcerative colitis of the mouse descending colon. Methods and Materials : Twenty-one rats were divided into 3 groups and treated as follows: the control group was untreated mice. The UCE group was ulcerative colitis elicited mice. The DJT group was Dojeckjiyu-tang treated mice after ulcerative colitis elicitation. The groups were examined with common morphology, paneth cells in intestinal crypt, absorptive cells and goblet cells in epithelium, cell division in mucose, COX-1 as mucosal protector, COX-2 (which appears to play an important role in inflammation), IL-2R-, ICMA-1-inducing cellular immuno-chainreaction, and the distribution of apoptotic cells. Results: 1. The morphology of colonic mucosa from UCE mice: the disappearance of epithelium and intestinal propria in hemorrhagic erosions were seen, but in the morphology of colonic mucosa from DJT-treated mice, the configuration of epithelium and intestinal propria were the same as normal. 2. The distribution of goblet cells and absorptive cells with microvilli in intestinal propria from UCE mice: a noticeable decrease of goblet cells and absorptive cells with microvilli were seen, but with the distribution of goblet cells and absorptive cells with microvilli in intestinal propria from DJT -treated mice, the configuration of goblet cells and absorptive cells with microvilli were the same as normal. 3. The immunohistochemical stain for BrdD in colonic mucosa and COX-1 in lamina propria from UCE mice: BrdU positive cells and COX-1 positive cells in the region of hemorrhagic erosion disappeared, but in the immunohistochemical stain for BrdU in colonic mucosa and COX-1 in lamina propria from DIT-treated mice, BrdU positive cells and COX-1 positive cells were seen. 4. The immunohistochemical stain for COX-2 in lamina propria, IL-2R-in lamina propria, intestinal propria and submucosa and ICMA-1 in intestinal propria and submucosa from DCE mice: a noticeable increase COX-2, IL-2R-, ICMA-1 positive cells were seen, but in the immunohistochemical stain for COX-2 in lamina propria, IL-2R-in lamina propria, intestinal propria and submucosa and ICMA-1 in intestinal propria and submucosa from DJT-treated mice, a numerical decrease of COX-2, IL-2R-, ICMA-1 positive cells was observed. 5. The distribution of apoptotic cells in epithelium and lamina propria from UCE mice: a noticeable increase of apoptotic cells in region of hemorrhagic erosion was seen, but in the distribution of apoptotic cells in epithelium and lamina propria from DJT-treated mice, a remarkable decrease of apoptotic cells was seen. Conclusions: According to the above results, Dojeckjiyu-tang has a moderate effect on ulcerative colitis in descending colon.

Objectives The purpose of this study is to investigate the anti-inflammatory effect of Lonicera Japonica-Glycyrrhiza Uralensis decoction extracts (LGE) on ulcerative colitis in children and adolescents. Methods Colitis was induced by DSS (Dextran Sulfate Sodium) in C57BL/6 mice. The sample mice were divided into group of four. The mice in the control group were not inflammation-induced. The control group was composed of untreated ulcerative colitis elicited mice. The mice in the experimental group were administered with Pentasa and another experimental group mice were treated with LGE after colitis elicitation. The effects on ulcerative colitis were evaluated by the morphological changes of colonic mucosa, decrease in the effect of pro-inflammatory cytokines ($TNF-{\alpha}$ and $NF-{\kappa}B$) and inflammatory cytokines (iNOS and COX-2) in the mucosa. Results LGE showed protective effects in DSS induced ulcerative colitis. LGE inhibited shortening of colon length and relieved the hemorrhagic erosion in colonic mucosa. LGE decreased pro-inflammatory cytokines ($TNF-{\alpha}$ and $NF-{\kappa}B$) and inflammatory cytokines (iNOS and COX-2). According to the GC/MS analysis, N-methyl pyrrolidone (NMP) was identified. Conclusions The result shows the clinical efficacy of LGE and demonstrates possible treatment options for ulcerative colitis. Further investigations for biological activity and chemical analysis of LGE will be needed.

Objectives: This study investigated the anti-inflammatory effects of Jageum-jung extract on Dextran sulfate sodium (DSS-induced) ulcerative colitis in mice. Methods: Ulcerative colitis was induced by DSS in Balb/C male mice. Ten mice were assigned to each of four groups: Ctrl (control), UE (ulcerative colitis-induced), PT (treated with pentasaccharide after induction of ulcerative colitis), and JT (treated with Jageum-jung extract after induction of ulcerative colitis). The effects of Jageum-jung extract were measured by restoration of the length of the intestine, degree of mucosal damage as seen with histochemistry, and changes of p-IkB, iNOS, COX-2, and caspase-3 determined by immunohistochemistry. Results: The recovered intestinal length of the JT group was longer than that of the UE group. In the colon mucosa of JT group, hemorrhagic lesions were reduced, and the mucus barrier was recovered. This group also showed inhibited production of inflammatory enzymes (iNOS, COX-2) through regulation of proinflammatory enzyme (NF-kB, p65) activity in the colon. In addition, caspase 3 activation induced apoptosis. By GC/MS analysis, azetidine was identified. Conclusions: This study confirmed the anti-inflammatory effects of jageum-jung extract, and suggests the possibility of using Jageum-jung extract to treat ulcerative colitis. Further experiments and research on the mechanism of Jageum-jung effects are needed.

Enterohemorrhagic Escherichia coli (EHEC) produces Shiga toxin, which causes diarrhea, hemorrhagic colitis, and hemorrhagic uremic syndrome. The Korea Center for Disease Control and Prevention (KCDC) has designated EHEC as a legal infectious disease and has conducted laboratory surveillance. This study aimed to compare the demographic, epidemiological, clinical, and laboratory characteristics of EHEC cases in Jeju Province between August 2017 and November 2023, notified by two registry routes. The data were sourced from the integrated disease health and health management system managed by the KCDC. Cases reported due to experiencing gastrointestinal symptoms, or contacts of each case were defined as the "symptomatic" group. In contrast, cases with positive findings during a health checkup or laboratory surveillance were defined as the "screening" group. The symptomatic and screening groups had 35 and eight patients, respectively. There were significant differences in the age and seasonal distribution. The selection group was 20-59 years old in the main age distribution and registered evenly throughout the four seasons. In comparison, the symptomatic group was younger or older and not registered in the winter. These findings may be used to establish a more appropriate surveillance system for diarrheal outbreaks.

Shiga toxin (Stx)-producing Escherichia coli (STEC) strains can cause broad spectrum of human disease, including diarrhea, hemorrhagic colitis, and the life-threatening hemolytic uremic colitis (HUS). We examined 868 samples was taken from bovine feces and carcass from January to December 2008 in Seoul. Twenty two (9.5%) shiga toxin -producing Escherichia coli were isolated from the 230 of bovine feces, and two (0.31%) were isolated from the 638 of carcasses. Serotype of E. coli isolates were O157 (10, 41.6%), O26 (10, 41.6%), O111 (1, 4.2%) and UT (3, 12.6%). In PCR, the isolates displayed three different stx gene combination (stx1 [2, 8.4%]), stx2 [3, 12.6%] and stx1 and stx2 [19,87.5%]). The eaeA and hlyA gene were found in 11 (45.8%) of the 24 strains. Saa gene was present only one strains (4.2%). Toxin typing using reverse passive latex agglutination test showed the same result in VT 1. But it showed different result in VT 2. In antimicrobial susceptibility test, all isolates were sensitive to amikacin, amoxicillin/clavulanic acid, ciprofloxacin and colistin. Eighteen strains (75.0%) of 24 isolates showed the multi-resistant patterns with over 3 drugs. PFGE was performed after the genomic DNA of twenty four isolates was digested with Xba I. the 24 isolates showed 7 (A~G) PFGE type.
