Pulmonary complications of ulcerative colitis are relatively uncommon and may present as a variety of disorders. Ulcerative colitis-related interstitial lung disease is extremely rare. There are a few case reports of nonspecific interstitial pneumonia in ulcerative colitis worldwide but none in Korea. We report a patient with ulcerative colitis related biopsy-proven nonspecific interstitial pneumonia, who responded to prednisolone (1 mg/kg) and mesalazine therapy.

Purpose: Pyoderma gangrenosum is a rare inflammatory, reactive dermatosis marked by painful cutaneous ulcer. The causes of pyoderma gangrenosum remain unclear. Gastrointestinal, hematological, rheumatological, and immmune disorders may be associated with pyoderma gangrenosum. The appearance of this disease may range from mild skin ulcers to life-threatening conditions. Generalized multiple ulcerative pyoderma gangrenosum is very rare. Here we report our experience with a case of multiple ulcerative pyoderma gangrenosum accompanied by ulcerative colitis. Methods: A 67-year-old man had cutaneous ulcers at multiple sites including the scalp, face, chest, abdomen, hands, and buttocks. He also developed gastrointestinal symptoms such as intermittent dyspepsia and bloody excrement. Debridement and irritation aggravated the disease progress. We gave a diagnosis of pyoderma gangrenosum with ulcerative colitis based on the clinical appearance and biopsy. The patient was treated with systemic intravenous steroid therapies and careful wound cares. Ulcers of the scalp and buttocks were treated with split thickness skin grafts. Results: Most of the multiple cutaneous ulcers were treated by systemic intravenous steroid therapies and wound cares. The rest of the ulcers were treated with skin grafts. Systemic intravenous steroid therapy was used to treat the ulcerative colitis. Conclusion: Generalized multiple ulcerative pyoderma gangrenosum is very rare. Without making an accurate diagnosis, hasty surgical treatments could aggravate the progression of the disease. Additionally, care should be taken to systemically treat underlying disease as well as administrating local treatments for the skin lesions. Intravenous systemic steroid therapy and skin grafts are useful treatments for generalized pyoderma gangrenosum.

Ulcerative colitis is a disease that causes inflammation in the mucosal or submucosal layer of the colon. Previous studies have reported that obesity increases the prevalence of ulcerative colitis and aggravates the progression. This study was therefore undertaken to investigate whether curcumin inhibits the progression of ulcerative colitis caused by obesity. Mice were bred on a high-fat diet to induce obesity, and curcumin was administered with the high-fat diet to confirm the anti-inflammatory effect. To induce ulcerative colitis, dextran sulfate sodium (DSS) was administered orally, and clinical symptoms of colitis were subsequently observed. For histological evaluation of curcumin, the colon, liver and abdominal fat tissue samples were prepared and analyzed by hematoxylin and eosin (H&E) and Alcian blue-periodic acid-Schiff (PAS) staining. Our results confirm that consumption of curcumin resulted in decreasing the score of the disease activity index, and inhibited shortening of the colon length. In addition, inflammatory cell infiltration and mucosal damage were inhibited in the colon tissue of ulcerative colitis exacerbated by obesity. We further confirmed that exposure to curcumin significantly reduced the steatosis area of the liver and adipocytes of abdominal fat. In conclusion, we believe that curcumin can be applied as a therapeutic agent to treat ulcerative colitis, by inhibiting the progression of colitis caused by obesity.

Purpose: The aim of this study was to cast light on initiating molecular events associated with the development of premalignant oral lesions induced by tobacco and/or areca nut. Method: Immunohistochemical analyses of cell cycle regulatory proteins (LIMD1, RBSP3, p16, RB, phosphorylated RB, p53), EGFR and SH3GL2 (EGFR associated protein) were performed with inflammatory/ulcerative epithelium and adjacent hyperplastic/mild dysplastic lesions. Results: No change in expression of the proteins was seen in inflammatory epithelium. Reduced nuclear expression of LIMD1 was evident in ulcerative epithelium. In hyperplastic lesions, reduced expression of RBSP3, p16, SH3GL2 and overexpression of p-RB and EGFR were apparent. Reduced nuclear expression of p53 was observed in mild dysplastic lesions. Conclusion: Our data suggest that inactivation of LIMD1 in ulcerative epithelium might predispose the tissues to alterations of other cell cycle regulatory and EGFR signaling proteins needed for the development of premalignant oral lesions.

In most cases, it is difficult to diagnose ulcerative diseases of the mouth, because they have many similar clinical appearance. For the diagnosis of oral ulcerative lesions, the clinician should check a detailed history of the patient and consider the relation with systemic diseases. In this case report, we introduced two patients with erythematous multiforme, phemphigus, lichenoid reaction and aphthous stomatitis as clinical diagnosis. The lesions were improved by medication.

The aim of this study was to evaluate the anti-inlfammatory effect of the extract of Zanthoxylum schinifolium on ulcerative colitis induced by 3% dextran sulfate sodium in the rat. The experiment animals were divided into six groups: control (normal), DDS-induced colitis, 1 mg/kg, 15 mg/kg and 150 mg/kg of the extract of Z. schinifolium and 150 mg/kg of 5-aminosalicylic acid (5-ASA) as comparative drug. Anti-ulcerative colitis effect was evaluated pathologically by disease activity index (DAI), the change of weight and myeloperoxidase (MPO) in colon mucosa. Treatment with 15 mg/kg and 150 mg/kg of the extract of Z. schinifolium significantly improved the gain of body weight and DAI as clinical symptoms, and reduced MPO and $PGE_2$ level as biochemical index. Especially, 150 mg/kg of the extract of Z. schinifolium showed markedly more improvement than the same dose of 5-ASA in all kind of index such as MPO, $PGE_2$ and DAI. These results suggest that Z. schinifolium mediated anti-inflammatory action on colorectal sites may be a useful therapeutic approach to ulcerative colitis.

In this study, immunohistochemistry was used to examine the changes in the density of colonic endocrine cells - argyrophil and argentaffin cells, chromogranin A (CGA), serotonin, somatostatin and glucagon-containing cells in trinitrobenzene sulfonic acid (TNBS)-induced rat colitis. Ulcerative colitis was induced by the instillation of 10 mg of TNBS into the colonic lumen through the anus. To confirm the inducement of ulcerative colitis, the macroscopic and microscopic scores as well as the colonic myeloperoxidase (MPO) activities were monitored for 8 days after TNBS instillation in the colonic lumens. In addition, the number of argyrophil and argentaffin cells, CGA, serotonin, somatostatin and glucagon-immunoreactive cells were counted in the colonic mucosa, respectively. After TNBS instillation into the lumen of the colon from the anus in rats, increases in macroscopic and microscopic scores in the colon tissues were observed along with increases in the colonic MPO activities. Therefore, ulcerative colitis was relatively well induced by the TNBS instillations. Marked decreases in the number of colonic endocrine cells were detected in the TNBS-treated animal compared to the sham control. These results suggest that colonic endocrine cells were also disrupted by TNBS-induced ulcerative colitis.

Objective The purpose of this study is to learn the anti-inflammatory effect of Douchi on ulcerative colitis (UC). Methods Three-month-old mice were divided into 4 groups as follows: control group (Ctrl), UC induced group (UCEG), Pentasa treated group after inducing UC (OPTG), and Douchi treated group after inducing UC (FGTG). NF-κB, p-IκB, iNOS, COX-2 were observed by immunohistochemistry and Masson trichrome, PAS, and Phloxine-tartrazine staining were used to observe histochemical changes. Results Inflammation indicators of the large intestine were significantly lower in FGTG than in the UCEG and OPTG. Also, indicators involved in pulmonary alveolar formation were significantly higher in the FGTG than in the UCEG and OPTG. Conclusions The result of this study suggests that Douchi extract was effective in ulcerative colitis and helped in the formation of alveolar. This result suggests that the lungs and colon are correlated.

Objectives : This study was carried out to investigate the effects of Soyumjungjang-tang(SJT) on the experimental ulcerative colitis induced by dextran sulfate sodium(DSS) in mice. Methods : Ulcerative colitis was induced through supplying 4% DSS solution as the drinking water for 7 days in 6-week-old male ICR mice. The colitic mice were divided into three groups: the sample groups were orally administered SJT in doses of 25mg/kg(S25 group) or 100mg/kg(S100 group) once a day for 10 days, from 3 days before starting drinking the DSS solution, and the control(C) group was administered normal saline instead of SJT. The DSS solution or SJT was not administered to the normal(N) group. The length of colon, histologic finding, the activities of myeloperoxidase(MPO) and alkaline phosphatase(AP), and the expressions of $IL-1{\beta}$, IL-6, COX-2, $NF-{\kappa}B$, and $I{\kappa}B$ in colonic mucosa was checked using immunoblot, ELISA, etc. The activities of chondroitinase, tryptophanase, ${\beta}-glucuronidase$ and ${\beta}-glucosidase$ in stool were also measured. Results : The length of colon shortened, histologic finding deteriorated, the activities of MPO, AP, chondroitinase, tryptophanase, ${\beta}-glucuronidase$ and ${\beta}-glucosidase$, and the expressions of $IL-1{\beta}$, IL-6, COX-2, $NF-{\kappa}B$ increased, and the expression of $I{\kappa}B$ decreased in the C group. All measures, except $NF-{\kappa}B$, were restored in S25 group, but some measures deteriorated more in the S100 group than in the C group. Conclusions : According to the above results, it is supposed that SJT has a potential therapeutic effect on ulcerative colitis.
