Gastric hemangiomas are rare benign vascular tumors that can cause severe gastrointestinal system bleeding. We presented the case of a neonate with fresh bleeding and melena from the orogastric tube and detected gastric hemangioma in esophagogastroduodenoscopic examination. Propranolol is widely used in treatment of cutaneous hemangiomas and non-gastric gastrointestinal system hemangiomas. However, the surgical approach is preferred for treating gastric hemangiomas, and there are few reports of gastric hemangiomas associated with non-surgical treatment. Gastric hemorrhage decreased with antacid and somatostatin treatment. Propranolol treatment was initiated before the surgery decision. After three weeks of treatment, we observed regression in the hemangioma with endoscopic evaluation. During the course of treatment, the patient's gastrointestinal system bleeding did not recur, and there were no side effects associated with propranolol.

In order to investigate the acute toxicity of autoxidized methyl linoleate(AOML) on the activity of serum enzymes in the mouse, we administered once 0.45ml of AOML to ICR strain mouse by using stomach tube. The following results were obtained: The total lactic dehydrogenase(LDH) activities in the serum of AOML group were generally increased than those of normal group. According to electrophoresis, the activities of LDH, were increased while those of LDH, were decreased. The activities of glutamic oxaloacetic transaminase(GOT), glutamic-pyruvic transaminase(GPT) and ${\alpha}-amylase$ in the serum of AOML group were increased more than those of normal group. The activities of alkaline phosphatase in the serum of AOML group were increased but those of isozyme were not confirmed in the normal and AOML group. In the serum protein of AOML group, albumin was increased, on the other hand ${\gamma}-globulin$ was decreased. At the peripheral blood slide smear, lymphocytes were significantly decreased but neutrophils were increased and the morphological change of erythrocytes was observed. From these results we conclude that the AOML fed to mouse influences on the activity of various serum enzymes and blood cells in the mouse.

The delayed gastric emptying flows have been visualized in this study when a gastric graft replaced an esophagus after esophagectomy. To construct visualization models for gastric grafts, the path data of gastric graft were extracted from the CT images for real patients and then the experimental models were made from silicone tube by considering elasticity of real stomach. During experiments, 200 ml of water or glycerin was poured into the gastric graft model and the gastric emptying time for total volume of fluid to pass pylorus was measured from the successive images captured by a high speed CCD. The gastric emptying time was compared according to the change of diameter and path (front or rear path) of gastric graft, and pyloroplasty or not. In case that the pyloroplasty was not conducted, the smaller was the diameter of gastric graft, the shorter was the gastric emptying time. However, if the pyloroplasty was conducted, the larger diameter of gastric graft was better for the gastric emptying. Although the rear path gave rise to longer gastric emptying time than the front path, it did not matter, if the pyloroplasty was conducted.

The occurrence of hiatal hernia after total gastrectomy with Roux-en-Y reconstruction is rare. We report the case of a 76-year-old man who presented with dyspnea, vomiting, and fever around 8 days after total gastrectomy with Roux-en-Y reconstruction. Abdominal computed tomography revealed a hiatal hernia containing part of the small intestine in the left thoracic cavity. Emergent reduction and repair of the hiatal hernia were performed later. Operative findings revealed that the Roux limb was incarcerated in the left pleural cavity. Esophagojejunostomy leakage, perforation of the small intestine with transient ischemic change, and pyothorax were also found. Thus, feeding jejunostomy, thoracoscopic decortication, and diversion T-tube esophagostomy were performed. Considering that the main cause of hiatal hernia is blunt dissection with division of the phrenoesophageal membrane, approximating the crus with 1 or 2 figure-8 sutures, according to the size of the defect, to prevent the incidence of hiatal hernia after total gastrectomy may be performed.

This study was examined the effects of Daesenggi-Tang on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed four weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and Daesenggi-Tang group(Daesenggi-Tang group). The results were as follows; 1. The gastrointestinal transit times was significantly decreased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Carmine red mixed with Daesenggi-Tang, as a marker, was administered through a gastric tube for stomach or intracecally by a chronically implanted catheter for colon transit. Small intestinal transit and large intestinal transit time were significantly decreased in Daesenggi-Tang administered group compare to basal diet. 3. The height of jejunal villi was developed in Daesenggi-Tang administered group compare to basal diet. The thickness of mucosa and muscle layer of colonic mucosa were significantly developed in Daesenggi-Tang administered group compare to basal diet group. 4. The numerical change of goblet cell in colonic mucosa was increased acid mucin stained alcian blue in Daesenggi-Tang administered group compare to basal diet and cellulose group. 6. HDL-cholesterol of plasma lipid was increased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Theses results suggests that Daesenggi-Tang may be used in prevention and treatment of constipation resulting in increase of fecal weight, decrease of gastrointestinal transit time, development of intestinal villi, intensify of stainability of acid mucin in colon.
