급성 위궤양은 위점막에서 세포증식과 세포사멸의 불균형으로 발병되어진다. 현재 Platycodin D (PD)는 항산화 및 항염증 등의 다양한 약리효능을 가진다고 보고되고 있다. 본 실험은 ibuprofen에 의해 유발된 급성 위궤양이 전처치한 PD에 의해 위궤양 보호효과를 가지는 가를 알아보기 위해 실시하였다. PD의 효능은 위점막에서의 COX-2의 발현과 더불어 위점막상피세포의 증생과 세포사멸정도에 의해서 평가하였다. 실험군은 정상대조군, ibuprofen 유발 위궤양군, 2.5 mg/kg PD 전처치군, 5 mg/kg PD 전처치군으로 분류하였다. 급성위궤양은 200 mg/kg의 ibuprofen을 하루에 3번 8시간 간격으로 경구 투여하여 유발하였다. PD는 5일간 경구로 하루에 한 번씩 전처치하였다. PD의 전처치가 ibuprofen에 의해 유발된 위궤양 병변을 유의적으로 감소시켰으며 과도한 위점액 분비로 인한 점액질의 소실을 억제하였다. 또한 PD 전처치가 위점막의 상피세포증식층에서 Ki-67 양성세포의 감소 및 세포사멸을 억제하였다. 추가적으로 PD의 전처치가 위궤양에 의해 증가된 COX-2 발현을 감소시켰다. 이상의 연구결과는 PD의 전처치가 ibuprofen에 의해 유발된 위점막손상에 있어 COX-2의 발현조절을 통하여 위점막세포의 증식과 사멸에 관여할 것으로 보여진다.

Equine gastric ulcer syndrome is one of the most frequently reported diseases in thoroughbred racehorses. Although several risk factors for the development of gastric ulcers have been widely studied, investigation of microbiological factors has been limited. In this study, the presence of Helicobacter spp. and the gastric microbial communities of thoroughbred racehorses having mild to severe gastric ulcers were investigated. Although Helicobacter spp. were not detected using culture and PCR techniques from 52 gastric biopsies and 52 fecal samples, the genomic sequences of H. pylori and H. ganmani were detected using nextgeneration sequencing techniques from 2 out of 10 representative gastric samples. The gastric microbiota of horses was mainly composed of Firmicutes (50.0%), Proteobacteria (18.7%), Bacteroidetes (14.4%), and Actinobacteria (9.7%), but the proportion of each phylum varied among samples. There was no major difference in microbial composition among samples having mild to severe gastric ulcers. Using phylogenetic analysis, three distinct clusters were observed, and one cluster differed from the other two clusters in the frequency of feeding, amount of water consumption, and type of bedding. To the best of our knowledge, this is the first study to investigate the gastric microbiota of thoroughbred racehorses having gastric ulcer and to evaluate the microbial diversity in relation to the severity of gastric ulcer and management factors. This study is important for further exploration of the gastric microbiota in racehorses and is ultimately applicable to improving animal and human health.

In order to study the immunohistochemical effects of Opae-san on gastric ulcer induced by HCl-aspirin in rats, experiments were done by oral administration and measure histological features of ulcer lesion, scaning electron microscopic appearance, the changes of numbers of parietal cells, chief cells, gastrin and somatostatin-immunoreactive cells. The obtained results are as follows: 1. Ulcerative lesions were numerously detected in control groups especially in junction of cardiac-fundic gastric mucosa and histologically very severe injury to gastric epithelium were observed too but in the Opae-san administrated groups, no gross lesion of ulcer were detected and histologically minor injury of gastric mucosa were observed. Most slight injuries to gastric mucosa were observed in 5 days after treatment. 2. The numbers of parietal cells were remarkably increased in control group but in Opae-san administrated groups appeared significant decrease compared to control groups. Most remarkably decrease of the numbers of parietal cells compared to control groups were observed in 5 days after treatment. 3. The numbers of chief cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably increase of the numbers of chief cells compared to control groups were observed in 5 days after treatment. 4. The numbers of gastrin-immunoreactive cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably decrease of the numbers of gastrin-immunoreactive cells compared to control groups were observed in 5 days after treatment. 5. The numbers of somatostatin-immunoreactive cells were remarkably decreased in control group but in Opae-san administrated groups appeared significant increase compared to control groups. Most remarkably decrease of the numbers of somatostatin-immunoreactive cells compared to control groups were observed in 5 days after treatment. 6. Scaning electron microscopically, severe denude and degeneration of gastric mucosa were observed in control groups but in Opae-san administrated groups the lesions were remarkably decreased compared to control groups.

A 73-year-old male visited our hospital with a complaint of general weakness. He underwent pyloric preserving pancreas-toduodenectomy due to ampullary cancer three years ago. Abdominal computed tomography scan at initial visit revealed multiple hepatic masses. A PET-CT scan showed multiple FDG uptakes at whole liver. He underwent hepatic artery infusion chemotherapy (HAIC) for five cycles. During the first cycle of HAIC, he developed gastric ulcer bleeding and endoscopic hemostasis was done successfully. Esophagogastroduodenoscopy after the 5^th cycle of HAIC revealed ulcer scar at gastric angle. PET-CT scan at 12 months showed no FDG uptake at liver, but a focal FDG uptakes at stomach and peri-gastric lymph nodes were newly developed. Esophagogastroduodenoscopy revealed about 3 cm sized mass at gastric angle. He underwent surgery and pathologic examination revealed large cell neuroendocrine carcinoma. We report a case of gastric large cell neuroendocrine carcinoma with liver metastasis treated with HAIC followed by surgery.

In order to study the effects of Jengjengamiyjintang on the duodenal ulcer induced by HCl-aspirin in rats, the changes of histological profiles, goblet cells(PAS-positive cells), and the distribution and frequency of cholecystokinin(CCK)-8 and serotonin-producing gastro-entero-endocrine cells were observed after oral administration of Jengjengamiyjintang. Histologically, very severe injury to duodenal epithelium were observed in control groups and these injuries were increased with time intervals. But in the Jengjengamiyjintang administrated groups, no gross lesion of ulcer were demonstrated and histologically minor injury to the mucosal epithelium were observed. PAS-positive cells were increased in the Jengjengamiyjintang administrated groups compared to that of control groups. Severe degranulation of CCK-8- and serotonin-immunoreactive cells were observed in control groups but these phenomenon was seldom in the Jengjengamiyjintang administrated groups. Serotonin-immunoreactive cells were significantly decreased in control groups but increased in Jengjengamiyjintang administrated groups compared with control groups. According to these result, it is suggested that Jengjengamiyjintang would accelerat the healing of the duodenal ulcer but the functional mechanisms were unknown.

The main cause of ulcer is pressure, which starts to develop when the critical body pressure (32mmHg) is exceeded, and when the critical time elapses, ulcer occurs. In this study, the keyboard mechanism of the medical bed with 4 bar links was adopted, and each key can be controlled vertically. A key has one servo drive and one sensor controller which hasseveral body pressure sensors. The sensor controllers and the servo drives are connected to the main controller by two CAN (Car Are Network) in series, respectively. By reading the maximum body pressure value of each keyboard sensor, and by calculating the error value based on the critical body pressure, the fuzzy controller moves each key so that the total error becomes zero. If the fuzzy controller fails, then it prevents ulcer by lifting and lowering the keys of the bed alternatively within a short time. Thus, the controller operates in two-stage. The validity and effectiveness of the proposed approach have been verified through experiments.

Banhasasim-tang(半夏瀉心湯), oriental medicine, has been used for the treatment of the gastric diseases and cimetidine, H2-receptor blocker, has been also used as the gastric ulcer remedy but has some side action. Therefore the concurrent administration of these two drugs may increase antiulcer activities and also decrease cimetidine's side action more than administrating one by one. In order to investigate antiulcer activities, some experiments were conducted. The concurrent administration of Banhasasim-tang extract(BS) and cimetidine(CM) given intraperitoneally (CM 50mg/kg + BS 300mg/kg and CM 50mg/kg + BS 500 mg/kg), significantly inhibited Shay, aspirin and indomethacin ulcers in rats.

The experimental study used in this paper was done to examine the clinical effects of Taeumchowetang for the gastric ulcer and the function of gastrointestinal tract using rats and mice which were administered orally the water extraction from Taeumchowetang. Then, the counter-action of the water extraction on the isolated ileum and gastric fundus, the inhibitory effects of pylorus-ligated ulcer and indomethacin-induced ulcer, the associations with gastric juice secretion, total acidity, pepsin output, the transportability in the small and large intestine, were studied with administering acetylcholine chloride and barium chloride. In addition, it was investigated whether the central nervous system related to pain control and sleeping time was influenced by Taeumchowetang. The following results have been obtained; 1. As resulting from injection of acetylcholine chloride and barium chloride into the isolated ileum of rats and mice, Taeumchowetang led to have an inhibitory effect on the muscle contraction of the ileum. Then, acetylcholine chloride was measured as lower effect than barium chloride 2. For the inhibitory effect on contraction for the gastric fundus strip in rats by either acetylcholine chloride or barium chloride, the one showed low inhibitory effect, on the other hand the other showed density-dependent effect. 3. The water extraction was given on the pylorus ligated ulcer with using two different administration groups of 1,300mg/kg and 2,600mg/kg, each result was measured as 22.9% and 36.5% for an ulcerous inhibitory effect (p<0.05). 4. According to the two administration groups, the preventive effect was tabulated 18.1% and 29.3% for indomethacin-induced ulcer (p<0.05, P<0.01). 5. For associations with gastric juice secretion, total acidity, pepsin output in the administration group 2,600mg/kg, Taeumchowetang was recognized as having an inhibitory effects related to suppressive actions involving gastric juice secretion(p<0.05), and free acidity(p<0.01), but there was no significant association with total acidity and pepsin output. 6. To know the transportability in the intestine, BaSO4 solution was used. The transportability of the small intestine in the administration group 2,600mg/kg was 22.2% which was statistically significant compared with the large intestine's transportability(P<0.01). 7. In the administration group 1,300mg/kg and 2,600mg/kg, analgesic effect with against acetic acid was measured as being 16.8% and 24.4% which was shown as statistically siginificant(p<0.01). 8. No statistically significant association between Taeumchowetang and sleeping time was found in both 1,300mg/kg and 2,600mg/kg by administering phenobarbital-Na. According to the results of this study, Taeumchowetang has agreed with the effects of literature review. Further more in this study, Taeumchowetang also has preventive effects on pylorus-ligated ulcer. Hence, Teaumchowetang can be significant effect such as both anti ulcer agent and increasing gastric activity for the patients who suffer from gastric ulcer.
