  • Adenosquamous carcinoma of stomach is a mixed glandular-epidermoid tumor where both components are neoplastic. Its incidence is extremely rare. The five theories on the origin of squamous components are 1) island of ectopic squamous epithelium in the gastric mucosa, 2) squamous metaplasia of gastric epithelium, 3) squamous differentiation in a preexisting adenocarcinoma, 4) endothelial cell differentiated toward squamous elements, and 5) totipotential undifferentiated cells of the gastric mucosa. We experienced three cases of adenosquamous carcinoma. Case 1 was a 71-year-old female patient. ; an ulcerative lesion was present in the pylorus, measuring 5cm in diameter. Case 2 was a 57-year-old male patient. ; an ulcerative lesion is present in the pylorus, measuring 6 em in diameter. Case 3 was a 58-year-old female patient. ; an ulcerative lesion was present in the body and fundus, measuring 10cm in diameter. Microscopic examination revealed a mixed malignant squamous and adenomatous component.

  • The object of this study was to observe the protective effects of Yijin-tang-gamibang (YJGMB), Yijin-tang has been traditionally used as Korean medicine for treating various digestive diseases. The study showed that it is effective on reflux esophagitis induced by pylorus and forestomach ligation in rats. Three different dosages of Yijin-tang-gamibang extracts, 300, 150 and 75 mg/kg, were once orally administered 1 hour before pylorus ligation. 6 groups, each of 8 rats per group were used in the present study. The results were compared with Omeprazole, antioxidant and proton pump inhibitor, 30 mg/kg treated group. Yijin-tang-gamibang extracts 300 mg/kg were showed similar or slightly lower effects as compared with 30 mg/kg of omeprazole in the present study. Detail mechanism studies should be conduced in future with the efficacy tests of individual herbal composition of Yijin-tang-gamibang and the screening of the biological active compounds in herbs.

  • Antral web is a rare cause of gastric outlet obstruction in neonate. It is a 2-4 mm thin mucous membrane that can be found anywhere from 1 to 7 cm proximal to the pylorus. The baby was born at gestational age of $32^{+1}$ weeks with 1,880 g as 2nd baby of dizygotic twin. After birth, the baby had constant non-bilious vomiting without feeding while he didn't show abdominal distension or discoloration. The infantogram showed distended stomach with distal small bowel gas. Upper gastrointestinal series revealed that the antrum was abruptly narrowed at 1 cm proximal to pylorus. We performed laparotomy at the 10th day after birth and excised the 2 mm-thick web circumferentially. He began milk feeding after 6 days and discharged uneventfully at postoperative 35 days with corrected age of $38^{+4}$ weeks with body weight 2,420 g. The antral web should be considered in the case of non-bilious vomiting in neonate.

  • Co-existing pyloric submucosal masses with hypertrophic pyloric stenosis (HPS) are very rare and treating these lesions is always a problem. A 20-day-old boy presented with recurrent episodes of projectile non-bilious vomiting lasting for 5 days. HPS was suspected due to the presenting age and the symptoms. The sonography demonstrated not only circumferential wall thickening of the pylorus, but also a pyloric submucosal mass. At laparotomy, a 0.8 cm sized pyloric submucosal mass was identified along with a hypertrophied pylorus. Pyloric excision was performed due to the possibility of sustaining the symptoms and malignancy. The pathological report of the submucosal mass was ectopic pancreas. Coexisting pyloric lesions can be diagnosed along with HPS, and surgical excision, not just pyloromyotomy, should be considered in these circumstances. To the best of our knowledge, this is the first case report of pyloric ectopic pancreas and HPS to be diagnosed concurrently.

  • In a preliminary screening of plant extracts for the antigastritic and antiulcer actions in rats, the methanol extracts of Taheebo showed positive activity in HCI . ethanol-induced gastric lesion. Among the systematic fractions of hexane, chloroform, butanol and water, the most potent $H_2O$ fraction reduced significantly HCI . ethanol-induced gastric lesion at the oral dose of 300 mg/kg. In pylorus ligated rats chloroform and butanol fraction showed decreases in the volume of gastric secretion and acid output of which effects were stronger in chloroform fraction. Further assays with hexane butanol and $H_2O$ fraction disclosed that it significantly suppressed the aspirin-induced ulcer. The butanol fraction reduced significantly acetic acid induced ulcer at the dose of 400 mg/kg. The butanol and $H_2O$ fraction reduced the malondialdehyde level in HCI . ethanol-induced gastric lesion. In pylorus ligated rats, chloroform and butanol fraction reduced the malondialdehyde level and in aspirin-induced ulcer, chloroform fraction reduced that levle. These results might suggest that the butanol and $H_2O$ fraction of Taheebo had inhibitory action in gastric lesion and ulceration through inhibition of gastric acid secretion and the decrease malondialdehyde level.

  • Infantile hypertrophic pyloric stenosis (IHPS) a common childhood disorders characterized by nonbilious projectile vomiting, an olive shaped mass in the right upper quadrant of the abdomen and visible gastric peristaltic wave in the upper abdomen. Its etiology and pathogenesis are not clear but abnormal nerve distribution of the pylorus has been $postulated^{2-6}$. We performed immunocytochemical staning to the pyloric muscle from 10 IHPS and 3 controls patients, utilizing specific monoclonal antibody to NCAM(neural cell adhesion molecule). In IHPS patients, the number of NCAM protein immunoreactive nerve fibers were less than that in normal subjects. Auerbach myenteric plexuse was well developed and interbundle nerve plexuse was present but nerve fibers supplying individual muscle cells in smooth muscle bundles were poorly developed. These results indicate reduction of innervation in smooth muscles in IHPS patients that possibly contributes to the pathogenesis of IHPS.

  • Trichosanthes cucumerina Linn. (cucurbitaceae) is widely used in Indian folk medicine for variety of disease conditions. The aim of present study was to evaluate the antiulcer activity of 50% ethanolic extract of fruits of Trichosanthes cucumerina Linn. (TCFE) using various experimental models of gastric and duodenal ulceration in rats. Oral administration of 50% ethanolic extract of fruits of Trichosanthes cucumerina Linn. was evaluated in rats against ethanol, aspirin and pylorus ligated gastric ulcers as well as cysteamine-induced duodenal ulcers. In all the models studied, the antiulcer activity of TCFE compared with that of cimetidine (100 mg/kg, p.o.), an $H_2$ receptor antagonist. TCFE showed significant antiulcer activity in ethanol-induced and aspirin-induced gastric ulcer models. In 19 h pylorus ligated rats, significant reduction in ulcer index, total acidity and pepsin activity was observed with TCFE, when compared with the control group. Mucosal defensive factors such as pH, mucin activity and gastric wall mucous content was found to be increased with TCFE. TCFE was also, afforded remarkable protection in cysteamine-induced duodenal lesions. The antiulcer activity of TCFE was comparable with that of cimetidine. Thus, TCFE possess significant antiulcer activity against both gastric and duodenal ulcers in rats. The antiulcer activity may be attributed to its cytoprotective action and inhibition of acid secretary parameters.

  • The regional distribution and relative frequencies of endocrine cells were studied immunogistochemically (PAP methods) in the alimentary tract of the tree frog, Hyla areorea japonica, using specific antisera against serotonin, somatostatin, bovine Sp-1/chromogranin (BCG), cholecystokinin (CCK)-8, vasoactive intestinal polypeptide (VIP), gastrin, bombesin, secretin and pancreatic polypeptide (PP). Six kinds of endocrine cells were identified in this study, These immunoreactive cells were located in the gastric glands of stomach regions and in the basal portion of the epithelium of the intestinal tract or esophagus with variable frequencies. They were spherical or spindle-shaped. Serotonin-immunoreactive cells were observed in the whole alimentary tract including the esophagus. Somatostatin-immunoreactive cells were also detected throughout the alimentary tract except the rectum. CCK-8-immunoreactive cells were observed from the pylorus to ileum. Vip-immunoreactive cells were restricted to the rectum. Bombesin-immunoreactive cells were restricted to the fundic gastric regions and gastrin-immunoreactive cells were restricted to the pylorus. However, no BCG-, secretin and PP-immunoreactive cells were demonstrated in this study. In conclusion, the regional distribution and relative frequency of the endocrine cells in the alimentary tract of the tree frog were similar to other anuran species, but some differences which may be caused by feeding habits and species specification were also observed.
