Behcet disease is relatively rare in pediatric age group. And the bowel involvement is seen in only a small portion of Behcet disease. However, once the bowel is involved it is potentially life threatening event. We report a 15 year old boy with intestinal Behcet's disease who had a history of recurrent oral and genital ulcers for several years. He underwent right hemicolectomy under the impression of intestinal tumor. Pathologically the lesion was a large sharply delineated ulcer in the cecum. The ulcer was round and deep with elevating margin, and was associated with thickening of affected intestinal wall. Microscopically, the ulcer base consisted of granulation tissue with fissurings and underminings. Characteristic phlebitis and occlusive arterial lesion were seen in intestinal wall. The inflammatory lesion was most pronounced around the ulcer but could be recognizable throughout the resected specimen.

Mucormycosis is a rare but invasive opportunistic fungal infection with increased frequency during chemotherapy-induced neutropenia. The clinical infections due to Mucor include rhinocerebral, pulmonary, cutaneous, gastrointestinal and disseminated diseases. The first two are the most common diseases and all entities are associated with a high mortality rate. Still hepatic involvement of Mucor is rarely reported. We experienced a case of hepatic and small bowel mucormycosis in a 56-year-old woman after induction chemotherapy for B-cell acute lymphocytic leukemia. Initial symptoms were a high fever unresponsive to broad spectrum antibiotics and pain in the left lower abdominal quadrant. It was followed by septic shock, deterioration of icterus and progressively elevated transaminase. An abdominal CT demonstrated multiple hypodense lesions with distinct margins in both lobes of liver and pericolic infiltration at small bowel and ascending colon. Diagnosis was confirmed by biopsy of the liver. The histopathology of the liver showed hyphae with the right-angle branching, typical of mucormycosis. The patient was managed with amphotericin B and operative correction of the perforated part of the small bowel was performed. However, the patient expired due to progressive hepatic failure despite corrective surgery and long-term amphotericin B therapy.

Inflammatory fibroid polyp occurs very rarely in the jejunum and gastrointestinal bleeding as an initial manifestation of inflammatory fibroid polyp has not been reported. We report a case of a jejunal inflammatory fibroid polyp presenting with melena for 10 days. Upper gastrointestinal endoscopic examination was negative for any active bleeding lesions and abdominal angiography failed to localize the bleeding site as well. In contrast, computed tomography of the abdomen demonstrated a segmental wall thickening of the jejunum with a tumor-like mass lesion associated with dense contrast enhancement. Consistent with this, technetium 99m red blood cells scintigraphy exhibited red cell pooling at the right upper quadrant. On exploratory laparotomy, there was an active bleeding from the site of the jejunal tumor and a segmental resection was performed. Histologically, the tumor lesion of the jejunum was consistent with inflammatory fibroid polyp. Thus, we conclude that the tumor lesion was a cause of the gastrointestinal bleeding.

A male, 5-year-old Jindo dog underwent enterectomy and enteroanastomosis due to ileus of the intestine at a local veterinary hospital. Grossly, the excised intestine showed markedly thickened multinodular masses in the serosal layer of the upper part, and soft-to-firm, creamcolored neoplastic masses that displayed extensive nodular mucosal protuberances into the lumen. The neoplastic masses were filled with large round cells that were ovoid in shape and they had pale and/or hyperchromatic nuclei. The neoplastic cells had mainly infiltrated into the mucosal and submucosal layers, and they had diffusely invaded the muscular and serosal layers. Therefore, the diagnosis of canine multiple intestinal malignant lymphomatous polyposis was made based on the gross and histopathological findings. The origin of these tumor cells was determined to be B-cells since they were positive for anti-CD20.

6.Intestinal Neuronal Dysplasia.
The Korean Journal of Gastroenterology 2007;50(3):145-156
Intestinal neuronal dysplasia (IND) type B is a disease of the submucosal plexus of intestine manifesting chronic intestinal obstruction or severe chronic constipation. IND is one of intestinal dysganglionoses and clinically closely associated with Hirschsprung's disease. Until recently, it is not fully clear whether IND is a congenital malformation or an acquired secondary condition related to some gastrointestinal problems. However, recently published data and consensus reports have enhanced our understanding of the pathogenesis and management of IND. The aim of this paper was to review the current state of knowledge regarding the controversial issues of IND including the etiology, classification, diagnostic criteria, and available therapeutic intervention.

An unusual localization of localized colitis cystica profunda in a 31-year-old man is described. The patient presented as anal bleeding and a protruding mass at the descending colon; the mass was polypoid and was made up of papillary epithelial hyperplasia with downward herniation of glands into the submucosa. Only one similar case involving a descending colon has been reported in the world literature.

OBJECTIVETo identify associated proteins involved in the molecular response of ischemic preconditioning (IPC) against intestinal ischemia/reperfusion (II/R) in the intestinal mucosa of rats.
METHODSSixteen SD rats were randomly divided into II/R and IPC groups. II/R injury in rats was produced by clamping superior mesenteric artery for 60 min followed by 60 min reperfusion. IPC was elicited by 20 min ischemia and 5 min reperfusion before index ischemia. The intestinal mucosa was scratched immediately after 60 min of reperfusion and total proteins were separated by immobilized pH gradient (IPG) based on two-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were analyzed using Image Master 2D Elite 5.0 image analysis software and identified by MALDI-TOF-MS. The biological information of these proteins was searched in the database of these peptide mass finger-printing (PMF). Western blotting and RT-PCR were used to validate the differentially expressed proteins.
RESULTSImage analysis revealed that averages of 1404+/-20 and 1338+/-20 were detected in II/R and IPC groups. A total of 10 spots yielded good spectra, and 8 spots matched with known proteins after database searching. These proteins were mainly involved in anti-oxidation, inhibiting apoptosis and energy metabolism. Western blot confirmed up-regulation of aldehyde dehydrogenase and RT-PCR confirmed up-regulation of aldose reductase in IPC group.
CONCLUSIONThe clues provided by comparative proteome strategy will shed light on molecular mechanisms of IPC against II/R injury.

9.Alteration of related transporters and its application significance in common intestinal disease, liver disease, renal disease and diabetes.
Acta Pharmaceutica Sinica 2015;50(2):127-132
Drug transporters are functional membrane proteins located in various tissues, which play vital roles in absorption, distribution and excretion of drugs, especially those located in intestine, liver and kidney. The expression and function of transporters will alter in diseases state, which affects the therapeutic effects of drugs by altering their pharmacokinetics. In this review, we focus on the alterations in related transporters and the effect on the drug therapy in common intestinal diseases, liver diseases, kidney diseases and diabetes mellitus.
