  • Ulcerative colitis is a form of inflammatory bowel disease characterized by chronic inflammation of the colon and rectum. The abnormal lesions in the digestive system caused by ulcerative colitis and intermittent colitis are of major clinical importance. MDM2 is a phospho-protein that functions as a ubiquitin ligase for p53. Recently, a T>G substitution in the promoter of the MDM2 gene (rs309) has been identified. In this case-control study, 174 ulcerative colitis biopsy samples and 82 control samples were collected from colonoscopy centers, hospitals, and clinics in Mazandaran and Gilan Provinces in Iran from October 2014 to May 2015. This MDM2 polymorphism was investigated in DNA samples (extracted from biopsy samples) by amplification-refractory mutation system polymerase chain reaction. The mean age of patients with ulcerative colitis was 46.5 years (range, 28 to 69 years) and that of control individuals was 45.3 years (range, 26 to 71 years). Seventy-eight patients (44.82%) were men and 96 (55.18%) were women. The distribution of the TT, TG, and GG genotypes was 17.93%, 27.59%, and 34.48%, respectively, in the ulcerative colitis patients and 31.70%, 24.40%, and 43.90%, respectively, in the control individuals (odds ratio of GG for ulcerative colitis, 7.142; 95% confidence interval, 2.400 to 9.542; p = 0.001). It was found that a single-nucleotide polymorphism at rs309 in the MDM2 gene was associated with ulcerative colitis. A direct relationship was found between age and ulcerative colitis, while no relationship was found with sex. This finding is of note because the occurrence of intestinal inflammation and subsequent ulcers can precede the development of cancer.

  • Objectives The purpose of this study is to understand the correlations between lung, large intestine, and skin of 3-week-old mice in which ulcerative colitis was induced, up on administration of Coptidis rhizome and Glycyrrhiza uralensis mixed extract. Methods Mice were divided into 4 groups as follows; no treatment group (Ctrl group), ulcerative colitis-induced mice group (UE group), ulcerative colitis-induced mice group after administering Pentasa (PT group), ulcerative colitis-induced mice group after administering Coptidis rhizoma and Glycyrrhiza uralensis mixed extract (CGT group). Mice were induced ulcerative colitis by Dextran sulfate sodium (DSS). After 5 days of administration, We obvserved anti-inflammatory effect, alveolar formation, and skin barrier control in the colon mucosa. Results The CGT group was observed arrangement of normal intestinal cells, Infiltration of less inflammatory cells. The CGT significantly decreased positive rseponse of $TNF-{\alpha}$, p-IkB, Caspase 3 in large intestine, and significantly increased positive rseponse of EGF, IGF, catalase, Filaggrin, involucrin, loricrin. Conclusions The results of this study show the correlation of Lung-Large intestine-Skin by administering Coptidis rhizoma and Glycyrrhiza uralensis mixed extract to ulcerative colitis-induced mice.

  • 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: 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.

  • Objectives: This study discusses the effects of constitution therapy on adolescent ulcerative colitis. Methods: A 12-year-old male patient was treated with western medication for six months and herbal medicine for one year and six years; however, his abdominal pain, mucousy stool, bloody stool, and diarrhea persisted. He was diagnosed as having Taeumin according to Sasang constitution classification and treated with Sasang constitutional medicine (i.e., Yeuldahanso-tang and food restrictions based on constitutional medicine theory). Before the first treatment, his Pediatric Ulcerative Colitis Activity Index (PUCAI) score was 35, but this score decreased to 15 within six months and was maintained at 10 by 18 months of treatment. He took the herbal medication for 38 months, and his PUCAI score was 0 at the end of treatment. His liver functioned normally despite long-term drug use, and a follow-up colonoscopy showed no ulcerative colitis except melanosis, which was presumed to be caused by the herbal medicine. Ulcerative colitis in pediatric adolescents requires treatment with pharmacotherapy and dietary control based on constitutional medicine to maintain disease remission. Conclusions: Constitutional therapy is effective for treating adolescent ulcerative colitis. More clinical data are needed for patients with ulcerative colitis.

  • 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.

  • Background : Sulfasalazine for treating ulcerative colitis has a clinical limitation due to its adverse effects. This case is about a patient with ulcerative colitis who could not tolerate sulfasalazine and was improved by Do-che decoction-based Korean medicine. Method and Results : Purulent and bloody diarrhea more than 20 times a day, mild fever, chilling and tenesmus were main symptoms of this patient who was diagnosed as ulcerative colitis 10 years ago. Do-che decoction-based Korean medicine which was recommended for purulent and bloody diarrhea in Dong-Ui-Bo-Gam, the classic literature of Traditional Korean Medicine was given to the patient for more than 1 month. After treatment, the frequency of purulent and bloody diarrhea, tenesmus and fever was decreased remarkably, and C-reactive protein, erythrocyte sedimentation rate, white blood cell count and maximum temperature also dropped to the normal range. Conclusion : Do-che decoction-based Korean medicine has a potential effect and may be a alternative therapeutic option in patients with ulcerative colitis who cannot tolerate sulfasalazine due to its adverse effects.

  • Objectives : This study was carried out to investigate the effects of Goihwa-san(GHS) against ulcerative colitis induced by DSS (dextran sulfate sodium). Method : The sample group was divided into three. The control group consisted of mice that were not inflammation-induced. The pathological group was composed of untreated colitis elicited mice. The experimental group was administered GHS after colitis elicitation. The effects on ulcerative colitis were evaluated by the morphological change of colonic mucosa, the anti-oxidant effect, HSP 70, NF-${\kappa}$B, COX-1, COX-2 and iNOS. Results : In terms of immunohistochemical changes, the distribution of COX-1 in mice treated with GHS increased noticeably more than that in the pathological group. The distributions of HSP70, NF-${\kappa}$B, COX-2, iNOS in mice treated with GHS more decreased than those in the pathological group. Regeneration of surface epithelial cell and goblet cell in mucosa was observed by optical microscope. The colonic lengths in GHS-treated mice were more elongated than those of DSS only treated mice. Conclusion : GHS is a candidate treatment for ulcerative colitis.
