Gastrointestinal complications, especially duodenal complication after cardiopulmonary bypass are rare, but often fatal. We experienced 1 case of duodenal ulcer bleeding and 2 cases of duodenal ulcer perforation developing after cardiopulmonary bypass from August 1994 to April 1996. In the case of duodenal ulcer bleeding, palpitation, dizziness, tachycardia and melena were the clues leading to diagnosis, and in the cases of perforation, abdominal distension with pain, tachycardia, hypotension, oliguria were the clues. Duodenal perforations were diagnosed by abdominal paracentesis. The patient with duodenal bleeding was treated by H-2 receptor antagonist, antacids and transfusion. And emergency laparotomy was required for the patients with duodenal perforation. In addition to ulcer prophylaxis including H-2 receptor antagonist and antacids, a high index of suspicion and timely surgery are necessary for early diagnosis and appropriate treatment of duodenal complication developing af er cardiopulmonary bypass.

Interferon inducible transmembrane protein (IFITM) family genes have been implicated in various cellular processes such as the homotypic cell adhesion functions of IFNs and cellular anti-proliferative activities. The present study aimed to investigate whether the polymorphisms of the IFITM2 and IFITM5 genes are associated with susceptibility to UC. We identified a total of thirteen polymorphisms (eleven SNPs and two variations) in the IFITM2 gene and twelve polymorphisms (eleven SNPs and one variation) in the IFITM5 gene, by the direct sequencing method. Genotype analysis in the IFITM2 and IFITM5 SNPs was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and Taq-Man probe analysis, and the haplotype frequencies of IFITM2 and IFITM5 SNPs for multiple loci were estimated using the expectation maximization (EM) algorithm. The genotype and allele frequencies of IFITM2 SNPs, as well as IFITM5 SNPs, in UC patients were not significantly different from those of the healthy controls. We also analyzed the combined frequencies of rs77537847 of IFITM1, rs909097 of IFITM2, and rs56069858 of IFITM5 in the UC patients and the healthy controls. Although the distribution of the major combined genotype frequency did not differ significantly between the healthy controls and the UC patients, the GGT combined frequency in the healthy controls was significantly different from that in the UC patients (P=0.002). This result suggests that the combined genotype of the IFITMs polymorphisms may be associated with a susceptibility to UC and could be a useful genetic marker for UC.

NSAID의 대표적인 유도체인 acetylsalicylic acid(aspirin)은 항혈전 작용이 있다고 밝혀졌고, 주기적인 aspirin의 투여는 심근경색을 예방할 수 있음이 보고되었다. 그러나, 위궤양등 부작용의 발현이 심각하여 위의 목적에 입각한 aspirin의 장기적인 사용에 제약이 되고 있다. 이에 더욱 안전한 유도체인 aspalatone을 합성하였고, 이 물질은 낮은 궤양 유발능을 보이는 유망한 유도체로 개발중에 있다. 본 연구는 aspalatone의 in vivo 항염증 활성을 밝히기 위하여 시행하였다.

Present study was carried out for development of a new supplementary product with gastroprotective effect. Natural Products mentioned that have GI protective property in Dongeuibogam and reports were evaluated anti-bacterial activity against Helicobacter pylori, then five heres were selected. The material used for the test were water extract of Alpinia oxyphlla (AO), Astragalus membranaceus (AM), Cinnamomum loureirii(CL), Citrus aurantium(CA), Amomum villosum(AV). They were tested individually on HCI ethanol-induced gastric lesion in rats, AV CL, AO showed the most significant effectiveness, respectively. Then two mixture different in their content ratio (P020701-1,-2) and complex with P020701-1 (CP) were made, and tested on HCI·ethanol, indomethacin-induced gastric lesion, aspirin-ligature, Shay ulcer and gastric secretion. P020701-1, -2 and CP showed significant effect on HCI ethanol, indomethacin-induced gastric lesion, and Shay ulcer. It can be regarded that the antigasuitic and anti-ulcerative effects of P020701- 1, -2 and CP are originated from reduction of total acid output identified by gastric secretion test.

The rhizoma of Zingiber officinale has been used as antiemetic, expectorants, stomachache relieving drugs and digestive accelerators. From the observation of antigastritic action of the methanol extract of the rhizoma, it was fractionated with hexane, chloroform, ethyl acetate and butanol, followed by bioassay on antigastritic and antiulcerative activity. The hexane and the chloroform fraction reduced significantly HCl ethanol induced gastric lesion at the dose of 370 and 210 mg/kg, p.o., respectively. On the gastric ulceration and gastric secretion in pylorus-ligated rats, the hexane fraction decreased the volume of gastric secretion and acid output, and also increased pH at the dose of 370 mg/kg, i.d.. It showed considerable curative ratio of acetic acid induced ulcer without inhibition of indomethacin induced gastric lesion. The methanol extract showed low acute toxicity with minimum lethal dose of more than 3000 mg/kg, p.o. in mice. In conclusion, Zingiberis rhizoma exhibited antigastric and antiulcerative activity which might be attributable to inhibition of gastric secretion. It is revealed that the active component may be present in the hexane fraction.

Sea cucumber, $Stichopus$ $japonicus$, is used not only as an outstanding tonic food but also as a traditional medicine for the treatment of asthma, hypertension, rheumatism, anemia, and sinus congestion. The purpose of this study was to examine sea cucumber as an anti-gastritis and anti-gastric ulcer in HCl-ethanol-induced gastric and $H.$ $pylori$-infected animal models. Thirty 7-week-old SD rats and Mongolian gerbils were divided into normal (Nor, n=6), control (Con, 60% HCl-ethanol+water, n=6), groupI (DSCI, 60% HCl-ethanol+sea cucumber 30 mg/kg, n=6), groupII (DSCII, 60% HCl-ethanol+sea cucumber 100 mg/kg, n=6), and group III (DSCIII, 60% HCl-ethanol+sea cucumber 300 mg/kg, n=6). Sea cucumber significantly suppressed gastric lesions and ulcers in the 60% HCl-ethanol-induced gastric model. Especially, 100 mg/kg of sea cucumber showed significantly inhibitory effects. In histopathological analysis of the $H.$ $pylori$ model, we found that sea cucumber augmented the eradication rates of $H.$ $pylori$ and attenuated gastric ulcer formation. Our results suggest that sea cucumber has inhibitory effects on gastritis and gastric ulcers. In addition, sea cucumber can be applied for the treatment of $H.$ $pylori$.
