Two cases of severe caustic injury of the hypopharynx, esophagus, and stomach are presented. Restoration of digestive continuity was accomplished by retrosternal isoperistaltic interposition of the transverse and left colon on the post-injury 73rd and 66th day respectively. The upper oro-colon continuity was made by a cervical approach, a vertical incision at the posterior hypopharyngeal wall, and interrupted one-layer sutures using 3-0 Dacron suture materials. The distal continuity was made by colojejunostomy between the transposed colon and proximal jejunum. There was no event after the operation in both cases. The posterior vertical hypopharyngotomy and hypopharyngocolostomy at the early post-injury period may be the preferred procedure to obtain normal deglutition in patients with esophageal stricture associated with hypopharyngeal injury.

Cochlosoma sp. infection was identified in a single case among 60 stunted diarrheic native turkey poults, Meleagris galopavo. A large number of the flagellated parasites was found free or within the intervillous spaces of the jejunum, ileum and cecum. Moderate enteritis was associated with the parasites. In TEM studies of the parasagittal sections of the parasite, a prominent ventral sucker like disc and flagella emerging from an opening on the ventrodorsal surface of the pyriform uninuclear parasite were found. The morphological characteristics of this protozoan match with those described for Cochlosoma anatis. The parasite could be considered as an intestinal pathogenic protozoan causing stunting and diarrhea in turkeys in Iran.

A 45-year old woman with congestive heart failure due to left atrial tumor was operated on. Three tumor masses arising from posterior wall, atrial septum, anterior portion of mitral valve were resected. Pathological diagnosis was malignant fibrous histiocytoma [MFH]. Above one case and sixteen previous reports are reviewed. Eleven cases out of 17 were females. The tumors all originated primarily in the left atrium and 8 had distant metastases. The metastatic sites are lung [4 cases], brain [2 cases], liver, jejunum, cervix and pleura etc. Careful pathologic study is necessary to differentiate the uniformly fatal MFH of the heart from the more common benign atrial myxoma. The treatment modalities are surgical resection, chemotherapy, and radiation therapy & the prognosis of intracardiac MFH is poor. We underwent partial resection of left atrial MFH and obtained symptom relief and patient still alive 7 months post-operatively in state of NYHA class II.

The cases of feline panleukopenia virus (FPLV) infection were diagnosed in three imported cats. All cats died within one week after mild emaciation, depression and anorexia. One cat showed yellowish watery diarrhea. At necropsy, all cats had segmental hemorrhage on the serosa and mucosa of the small intestine. Histopathologically, severe diffuse necro-hemorrhagic enteritis was observed in small intestine especially in jejunum and ileum. The crypts of Lieberkuhn were dilated and contained necrotic epithelia. Severely damaged epithelia of crypts were transformed into bizarre shapes. Multifocal lympholysis and lymphoid depletion were found in Peyer's patches and other lymphoid tissues. Direct fluorescent antibody (FA) test revealed the characteristic FPLV antigen in the cytoplasms of crypt epithelial cells. Based on the clinical signs, characteristic pathologic findings and FA test, these cases were diagnosed as FPLV infection. In our best knowledge, this study is the first case report for FPLV infection in imported cats in Korea.

Twelve colostrum-deprived piglets were inoculated oral1y with porcine epidemic diarrhea virus isolated from Korea. The piglets were euthanatized from at 12 hour postinoculation(PI) at 6-hour intervals. At 24 to 36 hours PI, all infected piglets showed severe yellowish to watery diarrhea, dehydration, depression, and anorexia. At necropsy, the intestinal wall looked thin, mesenteric vessels congested, and mesenteric lymph nodes edematous. The histological findings showed marked villous atrophy and fusion, severe degeneration of enterocytes and monomuclear cell infiltration in the lamina propria. On electron microscopy, villous epithelial cells of infected jejunum contained viral particles at 18 hour PI. The viral particles were pleomorphic spheres with a mean diameter of 95∼180nm including 18nm projections.

This is a report on four cases of bypass for esophageal stricture due to gastro-esophageal carcinoma in the Department of Thoracic Surgery, Chonnam University Hospital. Bypass was performed intrathoracal esophago-jejunostomy by a segment of jejunum. Three patients received end to end anastomosis and the other one side to end esophagojejunostomy. Postoperative results were as follow; There was no swallowing disturbance with regular diet and the patients appear to be more comfortable by bypass than gastrostomy or jejunostomy. Postoperative condition of all the patients was satisfactory because other organs were intact. However, two patients expired in 12 months and 6 months after operation by wide metastasis and the other 2 cases are living now with regular diet in 4 months and 2 months after operation.

Acute hemorrhagic enteritis was diagnosed in a seven-month-old male Shitzu dog dying of blood stained diarrhea and vomiting. Clinical findings were anorexia, dullness and sudden death after massive bloody diarrhea. At necropsy, main lesion was the hemorrhage in small intestine, mainly duodenum and jejunum. Microscopically, Gram positive long bacilli were massively detected on the mucose epithelial cells and necrotic debris of small intestine. Coagulative necrosis of epithelial cells and thrombosis of small intestine were also identified. However, there was no lesion of crypt epithelium. Mineral infiltration in both gastric mucosa and renal tubules was detected and proliferation of fibrous tissue was also shown in corticomedullary regions. In bacterial examination, C perfringens was isolated in anaerobic culture and it was confirmed to type A by multiplex PCR. Therefore, the dog was diagnosed as C perfringens type A associated enteritis with uremia.

To determine the radiosensitivity and dose-survival characteristics of jejunal crypt cells, experimental study was done using total 40 mice. Single irradiation of 1,000 rad to 1,600rad was delivered to whole bodies of mice, using a cesium 137 animal irradiator. The number of regenerating crypts per jejunal circumference was counted, by using a jejunal crypt cell assay technique, and dose response curve was measured. The average number of jejunal crypt Per circumference in control group was $140\pm10$. Mean lethal dose$(D_0)$ of moose jejunal crypt cell was 135rad.

Jejunal volvulus was diagnosed in a captive 12-year-old male striped hyena at necropsy. The animal was presented with decreased appetite, dullness, vomiting, and mild abdominal distention intermittently for about two months. Then, the animal was found anorexia, lethargy, depression, red brown colored vomiting materials, and decreased defecation from 10 days before death. At necropsy, jejunal volvulus was found about 1 m in length, and coalescence was observed at the inner membranes of jejunum. The parenchyma of the kidney was congested, and the bladder was filled with hematuria. These conditions might cause shock by renal failure that led to death. To prevent volvulus in a captive striped hyena, it is needed to improve zoo environment and early diagnosis using ultrasonography and X-ray.

The transfer of cupric sulfate across the rat small intestine in vitro was studied by perfusion method using the segments of everted rat small intestine. Copper transport was approximately propotional to the metal concentration in the mucosal solution and no difference was observed in the metal transport among rat duodenum, jejunum and ileum. It was suggested from these results that copper transport across the rat small intestine would occur by passive diffusion. The effect of various chelating agents on copper transport across the rat small intestine n vitro and its uptake by the intestine were also studied. Copper transport was greatly enhanced in the presence of EDTA and NTA. Copper uptake decreased to a greater extent in the presence of EPTA and NTA.
