Aim: P53, the most commonly mutated tumor suppressor gene in all types of human cancer, is involved in cell cycle arrest and control of apoptosis. Although p53 contains several polymorphic sites, the codon 72 polymorphism is by far more common. There are divergent reports but many studies suggest p53 pro/pro SNP may be associated with susceptibility to developing various cancers in different regions of the world. The present study aimed to find any correlation between H. pylori infection and progression of carcinogenesis, by studying apoptosis and the p53 gene in gastric biopsies from north Indian population. Materials and Methods: A total of 921 biopsies were collected and tested for prevalence of H. pylori by rapid urease test (RUT), imprint cytology and histology. Apoptosis was studied by the TUNEL method. Analysis of p53 gene polymorphism at codon 72 was accomplished by PCR using restriction enzyme BstU1. Observation: Out of 921 samples tested 56.7% (543) were H. pylori positive by the three techniques. The mean apoptotic index (AI) in the normal group was 2.12, while gastritis had the maximum 4.24 followed by gastric ulcer 2.28, gastropathy 2.22 and duodenal ulcer 2.08. Mean AI in cases with gastric cancer (1.72) was less than the normal group. The analysis of p53 72 SNP revealed that p53 (Arg/Arg), (Pro /Arg) variant are higher (40.59% & 33.66%) as compared to p53 pro/pro variant (25.74%) inthe healthy population. Conclusions: The North Indian population harbors Arg or Pro/Arg SNP that is capable of withstanding stress conditions; this may be the reason of low incidence of gastric disease in spite of high infection with H. pylori. There was no significant association with H. pylori infection and AI. However, there is increased apoptosis in gastritis which may occur independent of H. pylori or p53 polymorphism.

Objectives: The purpose of this study is to report bowel sound patterns recorded in 3 diseases associated with structural deformity of the pylorus-duodenum. Methods: : Bowel sound recording is a useful non-invasive tool for the evaluation of gastrointestinal motility. However, the difficulty in manual attachment of the electronic stethoscope on the abdominal wall and noise production against bowel sound signals have prohibited its widespread use. Therefore, I developed a new apparatus that eliminates the noise; it contains a sound absorbing device and a holder for the head of stethoscope. Using the new bowel sound recording system, bowel sounds of the patients were recorded repeatedly. The endoscopic and abdominal computed tomography findings were obtained from other hospitals' medical record, and all patients were confirmed to have structural deformity in the pylorus-duodenum. The records of each patient were compared and assessed. Results: : Patients had either duodenal ulcer scar, pyloric stricture, or far advanced malignant stomach cancer, as diagnosed by the gastroscopy. Their dominant frequency of bowel sound obtained from the new system was checked more than 2 times at regular intervals. All 8 recordings in the 2 patients with duodenal ulcer scar (5 times) or pyloric stricture (3 times) showed a decrease in postprandial than fasting dominant frequency. One patient with stomach cancer showed no significant change between postprandial and fasting states at 2 recordings. Conclusions: The analysis of dominant frequency in bowel sounds can indicate the existence of pyloric obstruction that could delay gastric emptying.

The purpose of this study was to evaluate the clinical efficacy and safety of NRM which was newly developed as a combination product containing antacids, digestive enzyme and herbal drugs, and OTA powder, called OHTA'S ISAN on the morret, for the treatment of various symptoms in upper gastrointestinal diseases. 63 patients were recruited, 36 as a treated group with NRM and 27 as a controlled one with OTA. Patients were randomly allocated to receive either NRM or OTA t.i.d. for treatment of upper G-1 symptoms and undergone endoscopic, symptomatic and clinical laboratory assessments before and after 2 weeks. The results were as follows; 1. The general improvement rates of subjective symptoms in upper G-1 diseases were observed in 100%(32/32) for NRM and in 92%(23/25) for OTA. 2. The overall effective rates in terms of the symptoms and endoscopic findings were 88.9%(32/36) for NRM and 85.2%(23/27) ,or OTA respectively. 3. In NRM group, no significant side effects by NRM were observed except a mild and transient vomiting in one patient, but in OTA group treatment was discontinued due to nousea in one patient, However, there were no clinically significant changes detected in the laboratory parameters. According to the result of this trial, it is cocluded that NRM was safe and effective and (but not statistically significant) was superior to OTA in the treatment of gastrointestinal diseases caused by gastritis, gastric and duodenal ulcer, functional gastrointestinal disorder, non-ulcer dyspepsia etc.

Helicobacter pylori antigen was prepared from an isolate from a patient with a duodenal ulcer. Serum samples were obtained from culture-positive H. pylori infected patients with duodenal ulcers, gastric ulcers and gastritis (n=30). As controls, three kinds of sera without detectable H. pylori IgG antibodies were used: 30 from healthy individuals without history of gastric disorders, 30 from patients who were seen in the endoscopy clinic but were H. pylori culture negative and 30 from people with other diseases. OFF-GEL electrophoresis, SDS-PAGE and Western blots of individual serum samples were used to identify protein bands with good sensitivity and specificity when probed with the above sera and HRP-conjugated anti-human IgG. Four H. pylori protein bands showed good (${\geq}$ 70%) sensitivity and high specificity (98-100%) towards anti-Helicobacter IgG antibody in culture-positive patients sera and control sera, respectively. The identities of the antigenic proteins were elucidated by mass spectrometry. The relative molecular weights and the identities of the proteins, based on MALDI TOF/TOF, were as follows: CagI (25 kDa), urease G accessory protein (25 kDa), UreB (63 kDa) and proline/pyrroline-5-carboxylate dehydrogenase (118 KDa). These identified proteins, singly and/or in combinations, may be useful for diagnosis of H. pylori infection in patients.

본 실험에서 흰쥐에 실험적으로 급성위염, 위궤양 및 십이지장궤양을 유발하고 지유 에틸아세테이트분획을 투여하여 항위염 및 항궤양에 미치는 영향을 검토하였던 바 다음과 같은 결과를 얻었다. 지유 에탄올 추출물을 n-헥산, 클로르포룸, 에틸아세테이트 및 n-부타놀과 물로 계통분획하여 농축하고 in vitro에서 항산화력을 측정한 결과 에틸아세테이트분획이 가장 우수하였다. 지유 에틸아세테이트분획 (SOL & SOH)의 HCI-EtOH급성위염에 대한 억제율은 각각 $27.7\%$, $31.7\%$로 대조약물로 사용된 cimetidine(CMT, $47.2\%$)의 억제효과에는 미치지 못했으나 CON에 비해 우수하였다. Indomethacin유발 위궤양에서, SOL & SOH의 위궤양억제율은 각각 $48.28\%$, $51.08\%$로 대조약물로 사용된 CMT($58.26\%$)의 억제효과에는 미치지 못했으나 CON에 비하며 유의 성있는 억제효과를 나타냈다. Shay 위궤양에서, 지유 에틸아세테이트분획을 십이지장에서 위내로 투여하였을 때 궤양 억제율은 SOL이 $42.86\%$로 CON에 비하여 억제되었으나 유의성 있는 효과는 아니었으며, 용량을 증량하여 투여한 SOH는 $47.71\%$로 대조약물인 omeprazol(OMP)의 저해효과($62.00\%$)에 미치지는 못했으나 CON에 비해 유의적민 효과를 나타내었다. 위액량 및 총위산분비량에서, 지유 에틸아세데이트분획 투여로 CON에 비하여 $32.11\%$와 $47.69\%$, $24.28\%$와 $34.69\%$의 감소로 유의성 있는 효과를 나타냈으며 OMP($55.69\%$, $41.62\%$)에 근접하게 감소되었다. pepsin 활성은 지유 에틸아세테이트분획 투여로 CON에 비해 각각 $19.55\%$, $\%21.45$가 저하되었으나 유의성있는 변화는 아니었다. 수침 $\cdot$ 구속 스트레스에 의해 유발된 궤양의 경우, SOL는 궤양억제율이 $9.23\%$ 로 CON와 유사하게 출혈을 동반한 깊은 궤양이 관찰되었으나 용량을 증량하여 투여한 SOH는 $48.45\%$로 CON에 비해 궤양의 깊이도 얕아졌고 출혈을 동반한 궤양도 감소되어 유의적인 억제율을 나타내었다. Cysteamine 유발 십이지장궤양에서, CMT는 유발된 십이지장 궤양을 CON에 비해 $54\%$ 정도 억제하여 우수한 항궤양효과를 나타냈고 시료투여군인 SOL 및 SOH는 CMT보다 우수하지는 않았으나 약 $35\∼42\%$ 정도의 궤양억제율을 나타냈다. 이상의 실험결과에서 지유의 항위염 및 항궤양효과는 항산화물질에 의한 결과로 판단되어지며, 앞으로 위염 및 위궤양 개선을 위한 건강 기능성 식품으로 개발이 기대된다

Lots of cases relating Helicobacter pylori infection to iron-deficiency anemia have been described in the literature and H. pylori infection has emerged as a cause of refractory iron-deficiency anemia which is unresponsive to oral iron therapy. H. pylori-associated iron-deficiency anemia can be treated by H. pylori eradication. It is not thought to be attributable to gastrointestinal blood loss, such as duodenal ulcer. The mechanism by which H. pylori infection contributes to iron-deficiency anemia remains unclear. However, four possible explanations can be posited for this relationship; occult blood loss secondary to chronic gastritis, reduced iron absorption due to hypo- or achlorhydria, increased iron consumption by H. pylori, and iron sequestration in gastric mucosa. H. pylori-associated iron-deficiency anemia seems to develop in populations at increased risk for iron depletion. When pubescent girls, including athletes, are found to have iron-deficiency anemia refractory to iron administration, they should be evaluated for H. pylori infection.

Helicobacter pylori is a spiral-shaped, microaerophilic human gastric pathogen causing chronic-active gastritis in association with duodenal ulcer and gastric cancer. To investigate the possibility of H. pylori outer membrane proteins (OMPS) as the oral vaccine antigens, sarcosine-insoluble outer membrane fraction has been prepared from H. pylori NCTC 11637. The major OMPs having apparent molecular masses of 62 kDa, 54 kDa and 33 kDa were detected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), which were identified as urease B subunit (UreB), heat shock protein (Hsp54 kDa) and urease A subunit (UreA), respectively. Minor protein bands of 57 kDa, 52 kDa, 40 kDa, 36 kDa and 31 kDa were also observed. The antigenicity of H. pylori OMPs and antigenic cross-reactivity among the strains were determined by immunoblot analysis using anti-H. pylori OMPs antisera or intestinal lavage solutions. The results showed that UreB, Hsp54 kDa, UreA and 40 kDa proteins vigorously stimulated mucosal immune response rather than systemic immunity. From this results, these proteins seemed to be useful as the antigen candidates for the oral vaccine. The immunoblotting results with surface proteins from eight isolated H. pylori strains were similar to that of H. pylori NCTC 11637. The IgA which had been arised from oral administration of H. pylori OMPs, was able to bind H. pylori whole-cells.

Background: N-Butyl Cyanoacrylate (NBCA) is a liquid embolic material that can be useful for transcatheter arterial embolization (TAE) of acute bleeding especially in patients with coagulopathy, because it does not depend on coagulation for its therapeutic effect. The aims of this study were to evaluate the clinical efficacy and safety of TAE with NBCA in acute bleeding patients. Methods: Between August 2003 and September 2004, TAE using NBCA for acute bleeding was performed in 23 patients (16 men, 7 women; mean age, 56.5years). The causes of bleeding were gastric ulcer (n=5), postoperative bleeding (n=4), post-biopsy bleeding (n=3), postpartum bleeding (n=3), duodenal ulcer (n=2), angiodysplasia (n=2), gastric lymphoma (n=1), iatrogenic injury (n=1), CMV gastritis (n=1), stab injury of the liver (n=1). TAE was performed using 1:3 mixtures of NBCA and iodized oil. The angiographic and clinical success rate, recurrent bleeding rate, procedure-related complication and clinical outcomes were evaluated. Results: The angiographic and clinical success rate was 100% and 91.3% (21/23), respectively. There was no serious ischemic complication. Recurrent bleeding occurred in 2 patients (8.7%) and they were managed with successful second TAE (n=1) and endoscopic treatment (n=1). Nine patients (39.1%) had coagulopathy at the time of TAE and clinical success rate in this group of patients was 88.9% (8/9). Conclusions: TAE with NBCA is highly effective and safe treatment modality for acute bleeding patients, especially when the patient has a coagulopathy.

Bezoars are collections or concretions of indigestible foreign material that accumulate and coalesce in the gastrointestinal tract; they usually occur in patients who have undergone gastric surgery and have delayed gastric emptying. Treatment options include dissolution with enzymes, endoscopic fragmentation with removal or aspiration, and surgery. Recently, the efficacy of nasogastric lavage or endoscopic infusion of Coca-Cola for the dissolution of phytobezoar have been reported. We report a case of phytobezoar successfully treated by oral administration and endoscopic injection of Coca-Cola. A 62-year-old woman was referred to Yeungnam University Hospital for epigastric pain. Upper gastrointestinal endoscopy revealed one very large, dark-greenish, solid bezoar in the stomach with gastric ulcer and duodenal bulb deformity. We performed endoscopic injection of Coca-Cola into the bezoar. The patient was instructed to drink four liters of Coca-Cola per day. At endoscopy two days later, the phytobezoar was easily broken into pieces. At endoscopy on the $11^{th}$ day of admission, the phytobezoar was decreased in size and removed by endoscopic fragmentation with a polypectomy snare. At follow up endoscopy after 13 days, the bezoar was completely dissolved.
