  • Madhuca indica has been used ethnomedically in Indian folks. In the present study we have investigated anti-inflammatory, anti-ulcer and hypoglycaemic effect of ethanolic extract (EE) and crude alkaloid extract of Madhuca indica seed cake on albino rats. The study showed that the EE had a significant, dose dependent anti-edematogenic, anti-ulcerogenic and hypoglycaemic activity, whereas the crude alkaloid extract exhibited a significant only. Both the extracts possess dose dependent inhibitory activity on carrageenan-induced edema, inhibiting prostaglandins or mediators involved in prostaglandin synthesis, the second phase of inflammation. The EE was significantly effective in protecting pylorus-ligation-induced gastric ulcers at a higher dose level. The active principle of EE seems to be a selective inhibitor of the COX II (prostaglandin synthesis) without important effect on COX I since, EE exhibited both anti-edematogenic and anti-ulcerogenic effect. The EE was effective in reducing the plasma glucose level in normal albino rats in a dose dependent manner, producing hypoglycaemic effect by stimulating the release of insulin from the ${\beta}-cells$ and/or increasing the uptake of glucose from the plasma.

  • Gastroduodenal intussusception is an invagination of part of the stomach through the pylorus and into the duodenum for a varying distance. The lead point of the intussusception is usually a benign gastric tumor such as gastric adenoma. We report a case of gastroduodenal intussusception in a 33-month-old boy presented with nonbilious vomiting and abdominal pain. Laparotomy revealed a gastroduodenal intussusception. After reduction and gastrostomy, a mass measuring $15{\times}5\;cm$ in size, was found at the leading point of the intussusceptum. The mass was resected, and pathological diagnosis showed a gastric hemangiomatosis.

  • Esophageal reflux of gastric contents causes esophageal mucosal damage and inflammation. Recent studies show that oxygen-derived free radicals mediate mucosal damage in reflux esophagitis (RE). Chlorogenic acid (CGA), an ester of caffeic acid and quinic acid, is one of the most abundant polyphenols in the human diet and possesses anti-inflammatory, antibacterial and anti-oxidant activities. In this context, we investigated the effects of CGA against experimental RE in rats. RE was produced by ligating the transitional region between the forestomach and the glandular portion and covering the duodenum near the pylorus ring with a small piece of catheter. CGA (10, 30 and 100 mg/kg) and omeprazole (positive control, 10 mg/kg) were administered orally 48 h after the RE operation for 12 days. CGA reduced the severity of esophageal lesions, and this beneficial effect was confirmed by histopathological observations. CGA reduced esophageal lipid peroxidation and increased the reduced glutathione/oxidized glutathione ratio. CGA attenuated increases in the serum level of tumor necrosis factor-${\alpha}$, and expressions of inducible nitric oxide synthase and cyclooxygenase-2 protein. CGA alleviates RE-induced mucosal injury, and this protection is associated with reduced oxidative stress and the anti-inflammatory properties of CGA.

  • A 1 year 2 months old, male Chihuahua dog weighing 0.92 kg was presented with a history of intermittent vomiting after eating since two weeks ago. Based on the history, clinical signs, physical examination, and contrast radiographs, the diagnosis of sliding hiatal hernia was made. Diaphragmatic plication, esophagopexy and left-sided gastropexy concurrently required for surgical correction but in this case, diaphragmatic plication and esophagopexy could not be applied because of the patient's special condition. Instead, left-sided gastropexy was performed with additional pyloropexy. To treat reflux esophagitis, cimetidine and sucralfate were administrated and patient was fed in an upright position. Two days after the surgery, the patient showed normal activity and after then there was not found recurrence or complication.

  • The delayed gastric emptying flows have been visualized in this study when a gastric graft replaced an esophagus after esophagectomy. To construct visualization models for gastric grafts, the path data of gastric graft were extracted from the CT images for real patients and then the experimental models were made from silicone tube by considering elasticity of real stomach. During experiments, 200 ml of water or glycerin was poured into the gastric graft model and the gastric emptying time for total volume of fluid to pass pylorus was measured from the successive images captured by a high speed CCD. The gastric emptying time was compared according to the change of diameter and path (front or rear path) of gastric graft, and pyloroplasty or not. In case that the pyloroplasty was not conducted, the smaller was the diameter of gastric graft, the shorter was the gastric emptying time. However, if the pyloroplasty was conducted, the larger diameter of gastric graft was better for the gastric emptying. Although the rear path gave rise to longer gastric emptying time than the front path, it did not matter, if the pyloroplasty was conducted.

  • The protective effects of the ethylacetate fraction of persimmon leaves(PEF) against experimentally induced gastric mucosal damage and gastric ulcers were evaluated in ratss. In prophylatic study, 100 mg/kg ethylacetate fraction of persimmon leaves (PEFH) exhibited a total protection of 73.8% and 65.7% against HCl-ethanol and 0.2N NaOH-induced gastric mucosal membrane lesions, respectively, which was superior to cimetidine 50 mg/kg, a commonly used anti-ulcer drug. PEFH showed excellent anti-ulcer effects against pylorus ligation induced gastric ulcers, compared to the control group, however, 50 mg/kg ethylacetate fraction of persimmon leaves (PEFL) and PEFH did not affect ulcers induced by water immersion stress, and that is inferior to cimetidine 50 mg/kg. In conclusion, the results suggest that the ethylacetate fraction of persimmon leaves can be used both in prevention and treatment of experimentally induced gastric mucosal damage and ulcers.

  • This nationwide survey was conducted to evaluate the current status of clinical practice for gastric cancer patients in Korea. The Information Committee of the Korean Gastric Cancer Association (KGCA) sent questionnaires containing 45 items about the preoperative diagnosis, medical and surgical treatment, and postoperative follow-up for gastric cancer patients to all 298 KGCA members in 108 institutes. Response rates were $32.6\%$ (97/298) for individuals and $59.3\%$ (64/108) for institutes. Most university hospitals responded (response rate of university hospitals: $71.6\%$, 48/67). The preoperative staging work up was performed primarily by abdominal CT, followed by bone scans, abdominal ultrasound, endoscopic ultrasound, and so on. Gastric cancer patients with stages II, III, and IV usually received adjuvant chemotherapy after a curative operation. About half of the surgeons regarded 2 cm as a safe resection margin in early gastric cancer and 5 cm in advanced gastric cancer. More than half of surgeons usually performed a D2 lymph node dissection in early gastric cancer and D2+$\alpha$ lymph node dissection in advanced gastric cancer. About $20\%$ of surgeons performed less invasive surgery and/or function-preserving surgery, such as a pylorus-preserving gastrectomy, a laparoscopic wedge resection, or a laparoscopy-assisted distal gastrectomy.

  • Regarding the removal of a gastric bezoar, laparoscopic surgery was performed and it was shown that the laparoscopic approach is safe and feasible. However, the laparoscopic method has the risk of intraabdominal contamination, when the gastric bezoar is retrieved from the gastric lumen in the peritoneal cavity. We developed and applied a new procedure for the removal of the gastric bezoar using one surgical glove and two wound retractors as a fashion of intragastric single port surgery. Herein we present this new minimal invasive procedure, so named "hybrid access surgery" which involves the use of existing devices and overcomes the weakness of laparoscopic removal of the gastric bezoar. Our new procedure, combining the concept of intragastric and single port access, is acceptable and feasible to retrieve the gastric bezoar. In the future, this procedure may be one of the alternative procedures for retrieving gastric bezoar even when it is incarcerated in the pylorus.

  • In order to investigate the regional distribution and relative frequency of the serotonin-, somatostatin- and motilin-immunoreactive cells in the gastrointestinal tract GIT) of the bullfrog (Rana catesbeiana) with developmental stages, group of bullfrogs subdivided into the tadpole with hindlegs, metamorphosed bullfrog with tail, 2 wk after metamorphosed bullfrog and adult bullfrog, were stained by immunohistochemical methods (PAP methods). Multifarious changes of the regional distribution and relative frequency of the gastrointestinal endocrine cells were observed as developmental stages but motilin-immunoreactive cell ere not detected in this study. Serotonin-immunoreactive cells were detected from 2 wk after metamorphosed bullfrog in the whole GIT. The positive cells were predominant in the pylorus regions. In the adult bullfrog, these cells increased in fundus. On the other hand, somatostatin-immunoreactive cells were observed from the tadpole with hindlegs in the stomach regions. In the metamorphosed bullfrog with tail, they were found in the whole GIT except for the ileum, and increased with developmental stages except for rectum. In the rectum, these cells were not detected after that period. Our results show that most of the immunoreactive cells appear from completed metamorphosed periods when the histological structure of GIT is completely differentiated.
