The pathological changes of the gastric rumen produced by rocking stress in 38 young male albino rats fed on low protein diet for a short period and in 20 young male albino rats fed on low protein diet only as the control rats, were investigated macroscopically and histologically. The ulcerative lesions of the gastric rumen were observed in 17 out of 38 experimental rats accompanied with hyperplasia and cornification of the ruminal epithelial layer and more or less edematous changes of the tunica propria near the ulcer site. The authors, finding of the ruminal ulcer in albino rats produced by rocking stress associated with feeding on a low protein diet for a short period were compared with the results of others. The authors discussed other opinions concerning of the gastric ruminal ulcer of the albino rats produced in various ways.

Gastrointestinal complications may follow organ transplantation. A patient who underwent heart lung transplantation due to patent ductus arteriosus and Eisenmenger's syndrome had an episode of acute cardiac rejection and was treated with a bolus injection of methylprednisolone followed by a high oral dose of prednisone. On the 22nd postoperative day, the patient complained of acute abdominal pain with muscular rigidity and a plain chest x-ray showed free air in the right subdiaphragmatic area. Under the suspicion of bowel perforation, an emergency laparotomy was performed and the perforated stomach had a wedge-shaped resection that included the perforation. Following the laparotomy, the postoperative course was uneventful and the patient was discharged on post-laparotomy day 10.

Seven patients with giant cavernous hemangioma of the liver were treated surgically with success at Pusan Gospel Hospital, Kosin Medical College, Pusan, from 1980 through 1989. They were 3 males and 4 females, and their ages ranged from 6 to 59 years. The tumors were located on the right lobe of the liver in 5 patients and on the left lobe in 2. The lesions were solitary in all patients, and their sizes varied from 4cm to 15cm in diameter. All patients underwent hepatic resection: 1 right hepatic lobectomy and 4 partial resections for tumors on the right lobe, and 1 left lobectomy and 1 left lateral segmentectomy for tumors on the left lobe. There was no surgical death, but 1 patient had a postoperative complication: multiple stress ulcers on the stomach and ileum. The pathologic diagnosis was cavernous hemangioma in all cases. In the long-term follow-up, there was no recurrence of preoperative symptoms in any patient.

Helicobacter pylori is a gram-negative bacterium that was first isolated in 1982. Since then, H. pylori infection in humans has been shown to be associated with gastritis, peptic ulcer disease, gastric carcinoma, and mucosa-associated lymphoid tissue (MALT) lymphoma as well. The epidemiology, transmission, and pathogenicity of H. pylori has been a subject of intensive study. Successful treatment improves the cure rate of peptic ulcerations and treatment with antimicrobials also decreases the recurrence rate of these diseases. Better regimens having less toxicity and a good eradication rate have also been developed. A better understanding of the pathophysiologic mechanisms relating to H. pylori induced mucosal damages would result in more options for the prevention of peptic ulcers and carcinogenesis. Korea has a relatively high incidence of H. pylori infection and gastric cancer. Growing interest has developed in view of its importance in being associated with various gastroduodenal diseases. Furthermore, along with a high incidence of H. pylori-related disease in Korea, because the interaction between H. pylori, host factors and environmental factors is important in disease pathogenesis, we need to have precise data on the characteristics of H. pylori-related diseases that occur in Korea. In the present report we review the epidemiology, transmission route, diagnosis, pathogenesis, treatment methods and relationship with gastroduodenal diseases with in special references to basic and clinical data that have been published.

OBJECTIVETo observe changes of plasma polypeptide hormone levels in rats with gastric ulcer after exposure to intense noise, and to discuss their mechanism.

METHODS80 Wistar rats were used in the study. Plasma levels of rat gastrin (GAS), motilin (MTL), osteocalcin (BGP), substance P (SP), neurotensin (NT) and somatostatin (SS) in rats were measured by radioimmunoassay.

RESULTS(1) In non-noise-exposure but with gastric ulcer group, the plasma MTL [(160.70 +/- 40.34) pg/ml] and BGP [(27.63 +/- 13.13) pg/ml] levels on 10 d after gastric ulcer model operation were remarkably higher than those in control group [(89.21 +/- 49.94) pg/ml, (9.10 +/- 1.38) pg/ml respectively] (P < 0.05 and P < 0.01), while the GAS level was remarkably descended [(107.00 +/- 21.75) vs (158.48 +/- 20.92) pg/ml] (P < 0.01). (2) In noise-exposure but without gastric ulcer group, the plasma MTL [(312.80 +/- 207.42) pg/ml] and BGP [(17.76 +/- 12.33) pg/ml] levels on 10 d were also significantly increased as compared with the control group (P < 0.01 and P < 0.05 respectively), while the GAS levels didn't change. (3) In noise-exposure + gastric ulcer group, the areas of gastric ulcer on 10 d and 40 d after noise and operation [(15.33 +/- 7.26) and (15.11 +/- 12.45) mm(2) respectively] were significantly larger than those of the control [(8.22 +/- 6.66), (3.67 +/- 9.90) mm(2)] (P < 0.05). The plasma MTL levels on 10 d and 40 d [(244.44 +/- 68.11) and (191.20 +/- 60.50) pg/ml respectively] were higher than those in control group [(160.70 +/- 40.34) and (93.10 +/- 52.90) pg/ml respectively] (P < 0.01).

CONCLUSIONIntense noise exposure may make the rat gastric ulcer worsened and induce negative effect on healing of it. The gastrointestinal endocrine would be disturbed by combined effect of intense noise exposure with gastric ulcer in rats.

A gastropericardial fistula, defined as penetration of a gastric lesion into the pericardium, is a rare occurrence. Such a fistula is usually associated with a huge ulcer in the gastric fundus, an ulcer within a hiatus hernia, a history of esophagogastric surgery, the concurrent use of non-steroidal anti-inflammatory drugs (NSAIDs), or Zollinger-Ellison syndrome. The patient in this case presented with shoulder pain and melena, caused by a gastropericardial fistula that had occurred as a late complication of postoperative esophagogastrostomy and a refractory gastric ulcer. Despite the severity of the condition, the patient showed great improvement after medical treatment and the fistula was cured at the end.

Traumatic brain injury (TBI) remains a complicated and urgent disease in our modernized cities. It becomes now a public health disease. We have got more and more patients in Neurosurgery Intensive Care Unit following motor vehicle accidents and others causes. TBI brings multiple disorders, from the primary injury to secondary injury. The body received the disturbances in the brain, in the hypothalamo-pituitary-adrenocortical (HPA) axis, in the gastric mucosa, in the immune and neuroendocrine systems. The mortality of TBI is more than 50 000 deaths / year, the third of the mortality of all injuries. Cushing ulcer is one of the severe complications of TBI and its mortality rate is more than 50%. Many studies have improved the management of TBI and the associated complications to give patients a better outcome. Furthers studies need to be done based on the similar methodology to clarify the different steps of the HPA axis and the neuroendocrine change associated. The aim of the present review is to assess the clinical and endocrinal features of hypopituitarism and stress ulcer following TBI.

Tissue plasminogen activator (t-PA) and plasminogen activator inhibitor type 1 (PAI-1) may be involved in the pathogenesis of peptic ulcers through suppression of fibrinolysis. This study was designed to investigate associations of t-PA and PAI-1 genes with clinical features of the patients with bleeding gastric ulcers. Eighty-four patients with peptic ulcers and 100 controls were studied between January 1998 and April 2000. We used polymerase chain reaction and endonuclease digestion to genotype for 4G/5G polymorphism in the promoter region of the PAI-1 gene and the Alurepeat insertion/deletion (I/D) polymorphism in intron h of the t-PA gene. Various clinical features, including lesion site, bleeding event, recurrence of ulcer, and rebleeding, were assessed using a multiple logistic regression model. The genotype distributions of both the t-PA and PAI-1 genes did not differ between the patient and control groups. The occurrence of the I/D or D/D genotype of t-PA was significantly higher in cases of duodenal ulcer (adjusted OR=4.39, 95% CI=1.12-17.21). When a dominant effect (i.e., 4G/4G or 4G/5G versus 5G/5G) of the 4G allele was assumed, the PAI-1 4G/4G genotype was independently associated with rebleeding after hemostasis (adjusted OR=5.07, 95% CI=1.03-24.87). Our data suggest that t-PA gene polymorphism is associated with duodenal ulcers, and that the PAI-1 gene may be a risk factor leading to recurrent bleeding after initial hemostasis.
