In order to study the effects of Jengjengamiyjintang on the duodenal ulcer induced by HCl-aspirin in rats, the changes of histological profiles, goblet cells(PAS-positive cells), and the distribution and frequency of cholecystokinin(CCK)-8 and serotonin-producing gastro-entero-endocrine cells were observed after oral administration of Jengjengamiyjintang. Histologically, very severe injury to duodenal epithelium were observed in control groups and these injuries were increased with time intervals. But in the Jengjengamiyjintang administrated groups, no gross lesion of ulcer were demonstrated and histologically minor injury to the mucosal epithelium were observed. PAS-positive cells were increased in the Jengjengamiyjintang administrated groups compared to that of control groups. Severe degranulation of CCK-8- and serotonin-immunoreactive cells were observed in control groups but these phenomenon was seldom in the Jengjengamiyjintang administrated groups. Serotonin-immunoreactive cells were significantly decreased in control groups but increased in Jengjengamiyjintang administrated groups compared with control groups. According to these result, it is suggested that Jengjengamiyjintang would accelerat the healing of the duodenal ulcer but the functional mechanisms were unknown.

Surgery has been the standard treatment for perforated duodenal ulcers, with mostly good results. However, the resolution of postoperative leakage after primary repair of perforated duodenal ulcer remains challenging. There are several choices for re-operation required in persistent leakage from perforated duodenal ulcers. However, many of these choices are complicated surgical procedures requiring prolonged general anesthesia that may increase the chances of morbidity and mortality. Several recent reports have demonstrated postoperative leakage after primary repair of a perforated duodenal ulcer treated with endoscopic insertion using a covered self-expandable metallic stent, with good clinical results. We report a case with postoperative leakage after primary repair of a perforated duodenal ulcer treated using a covered self-expandable metallic stent.

Eosinophilic gastroenteritis is a rare clinicopathologic entity of unknown etiology with a variety of digestive symptoms. The pathogenesis is poorly understood. Diagnostic criteria include demonstration of eosinophilic infiltration of the affected bowel wall, lack of evidence of extraintestinal disease, and exclusion of various disorders that could mimic similar conditions. The disease might involve any area of the gastrointestinal tract from the esophagus to the rectum, but the stomach and the proximal small bowel are most commonly affected. The clinical features depend on which layer and site are involved. We report the case of a 59-year-old male patient with a 3-week history of post-prandial vomiting with malnutrition and weight loss. An abdominopelvic CT showed a gastric outlet obstruction with diffuse wall thickening, as with linitis plastica. Three gastrofiberscopic biopsies showed chronic gastritis. We carried out a radical total gastrectomy with D2 lymph node dissection. The pathologic report revealed a mural type eosinophilic gastritis with a marked hypertrophic scar formation at the proper muscle layer. We report this case with a brief review of the literature.

Helicobacter pylori(H. pylori) has been associated with the cause of peptic ulcer and gastric cancer. H. pylori infection occur mostly during childhood and increase by aging. In route of transmission, Oral cavity does important role. So we employed this study to elucidate route of transmission by detection of H. pylori in infant saliva. We investigated 20 infants aged below 10 years and 20 teens aged below 20 years as study group and 71 adults aged 20 and over years as control group. H. pylori DNA was isolated from 5(25%) infants aged below 10 years, 6(30%) teens and 17(23.9%) adults by nested polymerase chain reaction(n-PCR). There was no statistically significant difference(P>0.05). The obtained results suggest that H. pylori infection is relatively common in saliva of Korean infant and oral cavity may be reservoir of H. pylori.

To identify, the effects of acua-acupuncture of Bletillae rhizoma extract on the duodenal ulcer induced by HCl-aspirin in rats, the changes of histological profiles, number of mucous-producing goblet cells (PAS-positive cells), and morphology and/or number of chole-cystokinin (CCK)-8 and serotonin-immunoreactive (IR) cells in the gastrointestinal tract were observed after acua-acupuncture of Bletillae rhizoma extract on Ganshu locus ($BL_{14}$). Samples were collected at 1, 3 and 5 days after treatment. Histologically, very severe injury, atrophy of villus, necrosis of epithelial cell and hemorrhage, to the duodenal mucosa including epithelium were observed in HCl-aspirin administrated control groups, and these injuries were increased with time intervals. But in acua-acupuncture groups and nontreated normal groups, no gross lesion of ulcer was demonstrated and histologically minor injury to the apex of villas epithelium was observed. Compared to the PAS-positive cells of the control groups, those of the acua-acupuncture groups were increased. Severe degranulation of CCK-8- and serotonin-IR cells were observed in the control groups but these phenomena seldom occur in the acua-acupuncture groups. Serotonin-IR cells were significantly decreased in control groups but increased in the acua-acupuncture groups compared to control groups. However, these degranulation of IR cells of the aqua-acupuncture groups were less severe than those of normal groups, and number of serotonin-IR cells were lower than those of normal groups but these phenomena were decreased with time intervals and in 5 days after treatment, they were observed like those of normal groups. These result indicated that acua-acupuncture of Bletillae rhizoma extract would be accelerated the healing of the duodenal ulcer but the functional mechanisms were unknown.

Purpose: This study was undertaken to evaluate the factors correlated with the clinical course and outcome in patients of Henoch-Sch${\ddot{o}}$nlein Purpura. Methods: The medical records of 104 children diagnosed with Henoch-Sch${\ddot{o}}$nlein Purpura (HSP) from January 1996 to April 2006 were reviewed retrospectively. The patients were divided into two groups: patients with Gastrointestinal (GI) symptoms and those without GI symptoms. When there were joint, scrotum, and renal symptoms except for skin lesion in whole HSP, those patients were excluded. The history of acute infection, duration of admission, treatment requirement, recurrence of HSP, CBC, stool occult blood test, abdominal ultrasonographic findings and GI endoscopic findings were reviewed. Results: Among 104 patients, patients with GI symptoms included 66 cases (63.5%), those without GI symptoms accounted for 38 cases (36.5%). GI symptoms included: abdominal pain in 57 cases (54.8%), vomiting 21 cases (20.2%), GI bleeding 5 cases (4.8%), nausea 3 cases (2.9%) and diarrhea 3 case (2.9%). Positive GI symptoms and GI mucosal lesions on GI endoscopy had a statistically significant correlation with increased admission duration, treatment requirement, recurrence of HSP, and positive stool occult blood. Six cases with small intestinal wall thickening were noted on abdominal ultrasonography. Six cases of hemorrhagic gastritis and hemorrhagic duodenitis, 3 cases of duodenal ulcer, 3 cases of hemorrhagic gastritis and duodenal ulcer, 2 cases of hemorrhagic duodenitis and colitis, and 1 case of colitis were noted on GI endoscopy. Conclusion: These results suggest that GI endoscopic examination may be helpful for the diagnosis and treatment of children with HSP.

As the experience of coronary artery bypass grafting (CABG) has been accumulated, the number of reoperation after CABG is increasing. We analyzed our clinical experience of redo-CABG. Material and Method: Fourteen patients who underwent redo-CABG between Jan. 1994 and Dec. 2002 were included in this study. The mean period from the first operation to reoperation was 66$\pm$56 (3∼157) months, and the average ages were 62.8$\pm$8.7 (51∼78) years. The survivors were followed up 39$\pm$29 (4∼101) months postoperatively. Indications of reoperation were stenosis or occlusion of previous grafts in 11 patients, progression of native coronary artery disease in one patient, and both etiologies in two patients. Result: There were two in-hospital mortalities (14.3%) resulting from low cardiac output syndrome, Postoperative morbidities were perioperative myocardiac infarction in 2 patients (14.3%), mediastinitis in one patient (7.2%), duodenal perforation in one patient, ischemic necrosis of the lower extremity in one patient, gastric perforation after mesenteric infarct in one patient, delayed brain infarct in one patient, and intraoperative splenic rupture in one patient. There was one late mortality at six months postoperatively during the follow up. There was no angina recurrence during the follow up. Conclusion: Although redo CABG demonstrated relatively high operative mortalities and morbidities, postoperative status and clinical outcome of the survivors were favorable.

A 12-year-old, 8.0 kg, spayed female, mixed-breed dog was presented to the Veterinary Medical Teaching Hospital of Chungnam National University (VMTH, CNU). That case has been growing up mass in her left upper hindlimb about for 2 years and has showed vomiting and anorexia for 3 days. The patient was diagnosed with mast cell tumor on the basis of fine-needle aspiration (FNA) cytology techniques. According to World Health Organization clinical staging system for diagnosing mast cell tumors, it was classified into stage IIIa. The patient was treated by adjuvant corticosteroid therapy, but complete surgical excision was not achieved by owner's request. In the early stage of therapy, the size of the mass was gradually reduced with only adjuvant glucocorticoid therapy, so the patient's general condition was maintained well. But after 53 days later, the treatmant was not effective anymore and mass size was increased. Two months later, she was euthanized because of intermittent vomiting and severe respiratory distress. Splenic mass, duodenal ulceration, liver mass and infiltrated mast cell tumor in upper hindlimb muscle region were found in necropsy examination.

Purpose: The aim of this study was to investigate the spectrum of gastrointestinal mucosal lesions in the children presenting with short-term abdominal pain. Methods: Thirty one children with short term abdominal pain for less than 1 month from January 1995 to May 2004 who were examined using gastrointestinal (GI) endoscopy were reviewed retrospectively. Children presenting with acute abdominal pain unrelated to proper GI were excluded from this study. Results: Male patients were 16 and female were 15. Three patients were 1~5 years old, 15 were 6~10 years old, and 13 were 11~15 years old. The duration of the abdominal pain was less than 7 days in 23 patients, 10 days in 1, 20 days in 2, and 30 days in 4. The major accompanying symptoms were vomiting (15), diarrhea (4), melena (1), hematemesis (1), and fever (2). Using endoscopy, 6 patients were found to have hemorrhagic gastritis, 5 nodular gastritis, 4 duodenal ulcer, 3 gastric ulcer, 3 reflux esophagitis, 2 nodular duodenitis, 2 superficial gastritis, 2 erosive hemorrhagic duodenitis, 2 ulcerative colitis, 1 duodenogastric reflux, and 1 esophageal polyp. Helicobacter pylori (H. pylori) infection was positive in 10 patients. The age and sex ratio, duration of abdominal pain, site of abdominal pain, and duration of abdominal pain between H. pylori- positive and negative children were different. However, only the site of abdominal pain (epigastric) showed statistical significance. All symptoms improved with medication for the GI mucosal lesions noted by the endoscopic findings. Conclusion: The author suggests that GI endoscopy be one of the important first steps in examinations to find out diverse GI mucosal lesions in the patients with short-term abdominal pain. Additionally, the examinations for H. pylori infection are important for these patients, also.
