  • The gastric endocrine cells of the Korean hedgehog, Erinaceus korean us were studied immunohistochemically. Seven kinds of endocrine cells-, gastrin-, somatostatin-, 5-HT-, glucagon-, BPP-, motiIin-and GIP-immunoreactive cells- were identified in this study. The chracteristic findings of the regional distribution and relative frequency of them were examined. Gastrin-immunoreactive cells were very numerously detected only in the pyloric region. Somatostatin-immunoreactive cells were more numerous in the pyloric region than in the cardiac and fundic regions. 5-HT-immunoreactive cells were more numerous in the cardiac and pyloric regions than in the tundic one. Glucagon-immunoreactive cells were found few or rarely in the fundic and pyloric regions. BPP-imunoreactive cells were numerously distributed in the pyloric region, moderately in the fundic region and few in the cardiac region. Motilin-immunoreactive cells were found rarely or few in the fundic and pyloric regions. GIP-immnuoreactive Cells were detected onIy in the pyloric region.

  • The regional distribution and the relative frequencies of endocrine cells were studied in nine portions of the blue fox GI tract, and the distribution pattern and cell types of the pancreatic endocrine cells were also studied in the pancreas by immunohistochemical method. Six kinds of immunoreactive cells were identified in the GI tract, and four kinds of immunoreactive cells were also identified in the pancreas. Although numerous 5-HT- and somatostatin-immunoreactive cells were seen throughtout the GI tract, somatostatin-immunoreactive cells were a few in the intestine. Very numerous Gas/CCK-immunoreactive cells were restricted generally in the pyloric region and duodenum. Numerous glucagon-immunoreactive cells were found in the stomach except the pyloric region, and generally a few in the intestine. Moderate number of BPP-immunoreactive cells were found in the stomach except the pyloric region, and a few in the large intestine. Numerous porcine CG-immunoreactive cells were restricted to the cardiac and fundic region. In the pancreas, four types of pancreatic endocrine cells-somatostatin-, glucagon-, BPP- and insuline-immunoreactive-were identified in the pancreatic islet and exocrine portion. These results suggest that the regional distribution, the relative frequencies and cell types of the GEP endocrine cells in the GI tract and pancreas varies considerably among the species.

  • Purpose: Radical surgery is the standard therapy for patients with resectable cardia cancer. In the case of type II disease with esophageal invasion, a transhiatal extended radical total gastrectomy is needed or a gastroesophagectomy through an abdomino-thoracotomy, depending on the extent of the esophageal invasion. We analyzed the indications and outcome of left colon interposition as an esophageal substitution. Materials and Methods: Between 1 January 1994 and 31 December 2006, 10 patients underwent left colon interposition after gastroesophagectomy through an abdomino-thoracotomy or the tanshiatal approach for type II cardia cancer at the Department of surgery, Yonsei University College of Medicine. The outcomes of these patients were reviewed and compared, with those who underwent a Roux-en-Y, by gender and age matched analysis, retrospectively. Results: There were nine males and one female with a mean age of 52.5 (range, 16~72). The operation time was $449.00{\pm}87.39minutes$. The mean distance between the proximal resection margin and the cancer was $6.56{\pm}3.65cm$; the maximum size of the tumor was $9.90{\pm}3.97cm$. These measures differed significantly from patients who underwent Roux-en-Y. The patients had a double primary cancer in the cardia and esophagus. There were no events of colon necrosis. However, a pneumothorax occurred in one patient (10%) and a proximal anastomotic stricture occurred in one patient. There were no reports of heartburn, regurgitation, thoracic or epigastric fullness, and one patient even gained weight, 16 kg. Conclusion: Colon interposition after esophagogastrectomy was safe and effective and should be considered as an additional surgical option for locally advanced type II cardia cancer patients with esophageal invasion.

  • We experienced a case of Achalasia, who had been impressed as a bronchial asthma and treated at a local clinic. Fluoroscopic findings revealed narrowed vestibular portion with markedly dilated body of the esophagus. Hypertrophied mucosal folds on lower portion of the esophagus were noticed by the esophagoscopy but no ulcerative lesion, nor mass were found. The symptoms such as dysphagia, regurgitation, cough and retrosternal discomfortness were markedly relieved by means of daily mercury bougienage for a month duration.

  • Melanoma is a malignant neoplasm of melanocytes most frequently arising from the skin, but primary melanoma can also arise from the mucosa of the gastrointestinal tract. Gastrointestinal melanomas are most commonly metastases from a cutaneous melanoma. Primary melanoma of the stomach is rare and carries a poor prognosis. Reported here is the case of a 75-year-old man with a primary gastric melanoma who presented with a melena, abdominal pain, and weight loss. Most cases of melanoma are treated by excision of the primary tumor. Patients with melanoma have been treated with adjuvant chemotherapy, radiation therapy, and immunotherapy. None of these modalities has been demonstrated to prolong the survival rate. To improve long-term disease-free survival, early diagnosis and surgical intervention are very important.

  • A 4-month-old, intact male, Tosa with a history of a regurgitation, vomiting, and weight loss for three weeks was presented to Animal Medical Center, Chonbuk National University. In Serial plain radiographs, a severely distended stomach was seen and ultrasonogram revealed a nonfunctional pylorus with normal layer comparable with an obstruction of pyloric region by pyloric achalasia. An esophagram and endoscopy revealed normal peristalsis with failure of the lower esophageal sphincter to open, supporting the diagnosis of esophageal achalasia. Megaesophagus was observed on reradiograph and esophagram 11 days later. The clinical signs and esophageal dilation were resolved without resorting to any treatment.

  • Endocrine cells in the cardiac and fundic regions of the Korean hedgehog were studied ultrastructurally. Five types of endocrine cells classified as EC, ECL, $D_1$. G and A-like cells were identified in these regions. EC cells contained pleomorphic granules, 170~500nm in diameter, with high electron density and highly dense bodies in a dense matrix. ECL cells were characterized by the presence of round or oval granules, 220~450nm in diameter, with high electron density. Some granules of ECL cells showed a small amounts of contents or empty. $D_1$ cells contained round and relatively small granules, 140~400nm in diameter, with low to moderate electron density. G cells were characterized by the presence of round or oval granules, 200~400nm in diameter, with moderate electron density. Some granules of these cells showed a narrow halo between the limiting membrane and the granular matrix. A-like cells contained round granules, 170~260nm in diameter, With high electron density. The granules of these cells showed homogeneous matrix surrounded by the tight membrane.

  • The regional distribution and relative frequency of endocrine cells in the GIT of the snakehead, Channa(Oph icephalus) argus were studied immunohistochemically. Five kinds of endocrine cells and one kind of nerve cell were identified in this study. A few numbers of secretin-immunoreactive cells were restricted to the cardia and fundus of the stomach. Moti-lin- and GRP-immunoreactive cells were rare in the epithelium of the distal and proximal intestines. PYY-immunoreactive cells were found in a few number in the pyloric caeca and were rare in the distal intestine. Substance P-immunoreactive cells were distributed relatively numerous from the fundus to the distal intetsine. Also, their nerve cells were detected in occurrence in the lamina propria in the distal intestine. No neurotensin-, met-Enk- and GIP-immunoreactive cells were found in the GIT of the snakehead.
