This study is a clinical report of one patient with symptoms remaining after western medical therapy for ulcerative colitis. Ulcerative colitis, a diffuse inflammatory disease of the mucosal lining of the colon and rectum, is characterized by a remitting and relapsing course. Therefore treatment is difficult and the proper treatment typically isn't established. We provided acupuncture-moxibustion therapy 28 times and prescribed Dansamboheol-tang gagam, which functions by nourishing the blood (補血), strengthening the spleen (健脾), adjustment of ki (理氣), removal of extravasated blood (祛瘀), and warming of the kidney (溫腎), for 30 days. The patient improved in quality of life and the symptoms disappeared. This study suggests that Dansamboheol-tang gagam, acupuncture, and moxibustion treatment has an effect on improving the symptoms remaining after western medical therapy for ulcerative colitis.

Objectives: The aim of this study was to investigate the effects of Gaejigayonggolmoryo-tang (GYT) on ulcerative colitis induced by dextran sodium sulfate (DSS) in mice. Methods: Colitis was induced by free drinking of 5% DSS in six-week-old male ICR mice. The experimental groups were the sample group, the control group, and the normal group. The sample group was treated with GYT for three days after being was given 5% DSS for five days. The control group was given water, instead of GYT, for three days after the five days of 5% DSS. The normal group was untreated (not given 5% DSS), for comparison purposes. Results: Cellular experiments showed that GYT inhibits the expression of the inflammatory enzymes COX-2 and iNOS, and the production of NO. Based on the primary cellular experiments, the effects of GYT on ulcerative colitis induced by DSS of mouse tissues were investigated. GYT reduced tissue damage and apoptosis by inhibiting the expression of the inflammatory enzymes $NF-{\kappa}B$ p65, COX-2, and iNOS. In the cellular experiment, GYT was more effective in inhibiting the expression of COX-2 than in inhibiting the expression of iNOS. GYT was evidently effective in tissues in inhibiting the expression of COX-2. Conclusions: Based on the results here, GYT may have therapeutic effects on ulcerative colitis induced by DSS. GYT is worthy of research and development as a COX-2 inhibitor and a potential drug for inflammatory bowel diseases from natural products. Further investigations for exact mechanisms will be needed.

Objectives : This study was to investigate the anti-oxidative and anti-inflammatory effect of Lonicera japonica water extracts (LE) on Ulcerative Colitis Induced by DSS (Dextran Sulfate Sodium) in Mice. Methods : Colitis was induced by DSS in Balb/c mice. The sample group was divided into three. The mice in control group were not inflammation-induced. The pathological group was composed of untreated colitis elicited mice. The experimental group was administered Lonicera japonica water extracts (LE) after colitis elicitation. The effects on ulcerative colitis were evaluated the anti-oxidant effect, inhibition of COX-2 mRNA expression, the morphological change of colonic mucosa, decrease effect of HSP 70 and COX-2 in mucosa. Results : The SOD ability of LE was dose-dependently increased and the LPS-induced COX-2 mRNA expression of LE was dose-dependently decreased. LE showed the protective effects on DSS-induced experimental colitis. LE inhibited shortening of colon length, the hemorrhagic erosion in colonic mucosa. LE also showed the decrease effect for HSP70 and COX-2 in mucosa. Conclusions : The current results demonstrate the clinical utility of LE in traditional medicine and indicate the possible treatments for ulcerative colitis from natural products. Further investigations for exact mechanisms will be needed.

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.

The purpose of this study was to examine the effects of Angelica gigas Nakai on ulcerative colitis. Mice were divided into 5 groups: Control group, DSS group, 5-ASA group, 50mg/kg Angelica gigas Nakai group, 100mg/kg Angelica gigas Nakai group. Four groups, excluding the control group, were fed a 5% solution of dextran sulfate sodium(DSS) in water for 7days to induce ulcerative colitis. Each water extract was administrated orally for 7 days in 5-ASA group, 50mg/kg Angelica gigas Nakai group and 100mg/kg Angelica gigas Nakai group. 5 groups were evaluated by weight, length of intestine, weight of spleen, disease activity index(DAI), amount of cytokine IL-6 production, thickness of bowel wall and degree of inflammatory cell infiltration and intestinal tissue damage. Comparing to DSS group, 100 mg/kg Angelica gigas Nakai group showed significant suppressive effect of weight loss until 4th day of experiment while 50 mg/kg Angelica gigas Nakai group showed no significant effect of suppression. Decrease of intestinal length, enlargement of spleen, intestinal tissue damage and thickening of bowel wall were significantly suppressed in both 50 mg/kg and 100mg/kg Angelica gigas Nakai group. Also disease activity and cytokine IL-6 production were inhibited significantly. Based on this result, Angelica gigas Nakai seemed to have anti-inflammatory effect and also seemed to suppress histological changes and aggravation of ulcerative colitis.

Ulcerative colitis, an inflammatory bowel disease, is primarily managed medically with a combination of 5-ASA and steroids. However, this chronic disease requires surgical management if symptoms persist or complications develop despite medical management. The clinical course, indications and outcome of surgical management of 21 patients under the age of 15 who were endoscopically diagnosed with ulcerative colitis at the Seoul National University Children's Hospital between January, 1988 and January, 2003 were reviewed. Mean follow up period was 3 years and 10 months. The mean age was 10.3 years old. All patients received medical management after diagnosis and 8 patients (38 %) eventually required surgical management. Of 13 patients who received medical management only, 7 patients (53 %) showed remission, 4 patients are still on medical management, and 2 patients expired due to congenital immune deficiency and hepatic failure as a result of sclerosing cholangitis. In 8 patients who received surgical management, the indications for operation were, 1 patient sigmoid colon perforation and 7 patients intractability despite medical management. The perforated case had a segmental colon resection and the other 7 patients underwent total colectomy with ileal pouch-anal anastomosis. One patient expired postoperatively due to pneumonia and sepsis. and 1 is still on medical management because of mild persistent hematochezia after surgery. Six other operated patients are doing well without medical therapy. Pediatric ulcerative colitis patients can be surgically managed if the patient is intractable to medical management or if complications such as perforation are present. Total colectomy & ileal pouch-anal anastomosis is thought to be the adequate surgical method.

Purpose: Inflammatory bowel disease (IBD) in Korea has been increasing in recent years, but accurate statistics about operations for IBD are lacking. The purpose of this study was to investigate the trends and current status of IBD surgeries in Korea. Methods: Using a national database from the Korea Health Insurance Review and Assessment Service, we analyzed data from patients who underwent surgery for Crohn disease and ulcerative colitis from January 2009 to October 2016. Results: The mean number of patients who underwent surgery for Crohn disease was 791.8 per year. Colorectal surgery, small bowel surgery, and anal surgery were performed fairly often (31.2%, 29.4%, 39.4%, respectively), and laparoscopic surgery continued to increase, recently exceeding 30%. About 50% of Crohn patients used biologics before and after surgery, and those patients also underwent a relatively high rate of anal surgeries (44.2%). The mean number of patients who underwent surgery for ulcerative colitis was 247.6 per year. Colorectal surgery accounted for more than half of all operations, and laparoscopic surgery has been increasing rapidly, having been performed in about 60% of patients in recent years. The incidence of colorectal cancer in patients with ulcerative colitis was very high and increased rapidly during the study period, reaching about 80%. Conclusion: The number of patients undergoing laparoscopic surgery for IBD in Korea has increased significantly. Biologics are actively used by patients with Crohn disease, with a high proportion of anal surgeries required. Many of the surgical indications for ulcerative colitis have shifted into colorectal cancer.

Protaetia brevitarsis (PB) extracts has been traditionally used as medicinal stuff to treat blood stasis, occlusion of menstruation, tetanus and liver cancer in Asian countries (Korea, Japan, China, Taiwan, India and Myanmar). Especially, Donguibogam, which is traditional korean medicinal book, described the PB extracts as traditional medicine to treat hepatic diseases and vascular disorders. The PB extracts has been considered as highly nutritional food. The major constituents of PB extracts are rich in protein, healthy fats, iron, calcium. Recent studies announced that PB extracts has hepatoprotective effect and anti-microbacterial effect. However, the effect of PB on ulcerative colitis has not been uncovered yet. The aim of this study was to examine the anti-inflammatory effect of PB extracts in dextran sulfate sodium (DSS)-induced colitis mice model. Cytotoxicity of PB was determined by MTT assay and the antiinflammatory effect of PB extract was investigated by measuring nitric oxide (NO) production. PB extracts did not show any cytotoxicity. AIso, PB extracts supressed NO production in LPS-stimulated mice peritoneal macrophages. To determine whether PB could be an effective treatment on ulcerative colitis, DSS was administered in BALB/c mice for 10 days. PB extract significantly improved the clinical signs of DSS-induced UC, including body weight loss, colon length shortening, and disease activity index increase, with histological markers of colon injury. These findings indicated the possibility of PB as a therapeutic agent on ulcerative colitis.

Tofacitinib, a Janus kinase 1 and 3 inhibitor, is mainly metabolized by CYP3A1/2 and CYP2C11 in the liver. The drug has been approved for the chronic treatment of severe ulcerative colitis, a chronic inflammatory bowel disease. This study investigated the pharmacokinetics of tofacitinib in rats with dextran sulfate sodium (DSS)-induced ulcerative colitis. After 1-min of intravenous infusion of tofacitinib (10 mg/kg), the area under the plasma concentration-time curves from time zero to time infinity (AUC) of tofacitinib significantly increased by 92.3%. The time-averaged total body clearance decreased significantly by 47.7% in DSS rats compared with control rats. After the oral administration of tofacitinib (20 mg/kg), the AUC increased by 85.5% in DSS rats. These results could be due to decreased intrinsic clearance of the drug caused by the reduction of CYP3A1/2 and CYP2C11 in the liver and intestine of DSS rats. In conclusion, ulcerative colitis inhibited CYP3A1/2 and CYP2C11 in the liver and intestines of DSS rats and slowed the metabolism of tofacitinib, resulting in increased plasma concentrations of tofacitinib in DSS rats.
