Propolis, a natural resinous compound collected from honey bees, contains many biochemical constituents and has been used in traditional medicines as early as 300 B.C. Recently, it has been reported to possess many biological activities such as antibacterial, antiviral, fungicidal, local anaesthetic, immunostimulating, antiinflammatory and free radical scavenging properties. This study was performed to investigate the pharmacological effects of the propolis extract and fractions on the gastric lesion and ulcer. The ethanol extract was fractionated with hexane, toluene and ethyl acetate. Followed by bioassay on antigastric and antiulcer activity. Propolis ethanol extracts(500, 750, 1,000, 1,500 and 2,000 mg/kg) showed the protective effect on HCl·ethanol-induced gastric lesion and the antisecretory effect against Shay’s gastric secretion in pylorus-ligated rats in a dose related manner. In the animal models of HCl·ethanol, aspirin-induced gastric lesion and Shay’s gastric secretion, the hexane and toluene fraction of propolis significantly reduced the length of gastric lesion and the acid secretion. These data showed that the gastric protective effects of propolis might result from reduction of acid secretion through the inactivation of H+/K+ATPase activity.

A 58-year-old male patient visited our hospital for epigastric discomfort and dysphagia which had developed 5 months earlier. He was diagnosed with esophageal cancer at the mid-thoracic level based on radiologic, endoscopic, and histologic examinations. An esophagectomy(Ivor Lewis technique) was done to treat the esophageal cancer. He was doing well until the 20th postoperative day when he began to complain of cough, sputum, fever and chills, Subsequently, thereafter, abdominal pain and generalized abdominal tenderness developed on the 22nd postoperative day. Upon gastrofiberscopy and esophagographic examinations, he was diagnosed with gastrobronchial fistula and an emergency operation was performed. On operative findings, the gastric fundus was perforated and directly connected to the abscessed cavity of the right upper lobe due to a gastric ulcer. We, herewith, report this case after review of the literature.

복통은 말 그대로 '배가 아픈 것'을 말하며, 한 번쯤 겪어보지 않은 사람이 없을 만큼 흔한 증상이다. 복통은 흔한 만큼 그 원인도 다양하다. 소화불량, 역류성 식도염, 과민성 대장증후군, 간염, 위궤양 등 비교적 널리 알려진 질병도 있지만 크론병, 게실염 등 일반에게는 생소한 질병도 있다.

To reveal the association between blood selenium level and the gastric diseases, 180 persons received the gastrofiberscopic examination at the outpatients department of the two university hospitals from July to September 1987, after the exclusion of the persons having the esophageal varix, were randomly selected. Their general characteristics such as age, sex and educational level and so on, were inverstigated. Five mi venous blood was collected from each subjects and stored at $0^{\circ}C$ in heparinized vaccum tube. The blood selenium level was measured by the flameless atomic absorption spectrophotometry. In the procedure of data analysis, five subjects having benign tumor and anomaly of the stomach, were also excluded. The mean blood selenium levels of the $155.5{\mu}g/{\ell}$ among gastritis cases, the $154.8{\mu}g/{\ell}$ gastric ulcer and the $133.0{\mu}g/{\ell}$ gastric malignancy were significantly lower(p<0.05) than that of the $173.3{\mu}g/{\ell}$ among normal controls. In men the mean blood selenium levels .among gastritis, gastric ulcer and gastric malignancy cases were significantly lower(p<0.05) than that among normal controls. In females, the mean blood selenium levels among gastritis and gastric maligancy cases were significantly lower(p<0.05) than that among normal controls($169.7{\mu}g/{\ell}$), but that among gastric ulcer cases($177.7{\mu}g/{\ell}$) was not significantly higher. In the logistic analysis, coefficient of the blood selenium level was -0.0436(p<0.05 : odds ratio 0.957) for gastritis, -0.0197(p=0.17 : 0.981) for gastric ulcer, -0.4876(p<0.05 : 0.614) for gastric malignancy and -0.0411(p<0.05 ; 0.960) for gastric diseases including the gastritis, the gastric ulcer and the gastric malignancy. These data support the hypothesis that the gastric diseases are to be associated with the low selenium level but, for the gastric ulcer, the further research is recommended.

Sanguisorba officinalis L. has been used as a traditional remedy for arthritis, neuralgia, diarrhea, vomiting, gastric ulcer and gastro-intestinal disorders. This study was performed to investigate the protective effects of ethylacetate fraction of Sanguisorba officinalis L. ethanol extract (SOE) on the gastric mucosal damage and gastric ulcer induced by HCI-ethanol, indomethacin, Shay-ligation method, restraint and water-immersion stress, and cysteamine in rats. The experiment animals were divided into four groups: a negative control group (CON), positive control group (cimetidine 100 mg/kg-CMT or omeprazol 100 mg/kg administrated group-OMT), SOE 200 mg/kg administrated group (SOL) and SOE 400 mg/kg administrated group (SOH), respectively. Rats were given an oral or intraduodenal administration of SOE, and all SOE treatment groups compared with the CON significantly inhibited HCI-ethanol-induced acute gastritis and indomethacin-induced gastric ulcers in dose-dependent manner, of which effects were lower in a positive control drug (CMT). The inhibition rates ($\%$) on the acute gastritis induced by HCI-ethanol and the gastric ulcers induced by indomethacin in rats, 17.66$\%$ and 48.28$\%$ in SOL, 21.71$\%$, and 51.08$\%$ in SOH, and 47.26$\%$ and 58.26$\%$ in CMT compared with CON, respectively, In pylorus ligated rats, the groups of SOE showed decreases in the volume of gastric secretion and acid output. However, no significant differences were observed in the pepsin activity between treated groups . In addition, SOH also depressed gastric ulcers induced by restraint and water-immersion stress and duodenal ulcers induced by cysteamine. These results suggest that Sanguisorba officinalis L. has remarkable antigastric ulcer effects and could be developed as a new antigastric ulcer agents.

Purpose: We are going to establish the efficacy of endoscopic examinations in diagnosing and treating upper GI bleeding in full term neonates. Methods: We retrospectively reviewed newborns who underwent endoscopic examination because of hematemesis from July 1998 to April 2001. Results: Gestational ages were between 38 and 41weeks, and birth weights were between 2,730 and 3,400 gm. Total of 9 patients were reviewed. Endoscopic examination revealed gastric ulcer in 6 cases, multiple erosions in 2 cases and negative finding in 1 case. All 6 gastric ulcers were multiple and among them 2 patients endoscopic hemostatic therapy. No complication due to the procedure was noticed. Five patients recieved transfusions. All 9 cases were cured through conservative and endoscopic therapy without recurrence. Conclusion: The common cause of upper GI hemorrhage in newborns with no preceding disease turns out to be multiple gastric ulcers and the prognosis is good. The endoscopic approach is useful in diagnosing and treating upper GI bleeding in newborns.

Bamboo salt has been used as a traditional remedy for gastric ulcer and gastro-intestinal disorders. It is produced by baking the salt packed in bamboo cylinder nine times under the fire of pine tree. Three of commercially available bamboo salt products (bamboo salt A, B, and C) were characterized by qualitative and quantitative analyses using inductively coupled plasma (ICP) spectrometer, ion chromatograph (IC), X-ray diffractometer (XRD), and electron microscope (EM). Compared with crude salt, the contents of iron, silicon, potassium, and phosphate in the bamboo salt products were higher whereas the sulfate content was lower. Water-insoluble fraction of bamboo salts contained the following compounds; MgO, $SiO_2,\;Mg_2Si0_4,\;and\;CaMgSi0_4$. The study on the microscopic structures of the bamboo salts were shown to have smooth surface and fused shape compared with crude salt. Among the three bamboo salt products, product A was used to test a possible inhibitory effect on gastric acid secretion. Each test material (bamboo salt A, crude salt, and reagent-grade NaCl) was given orally to Sprague-Dawley rats at doses of 0.2, 1.0, and 2.0 g/kg for 28 days before pyrolus ligation. Twenty four hours after the last administration of the test materials, volume, pH, total acidity, and pepsin activity of gastric juice were measured by the Shay-ligation method. No significant differences were observed in the secretion of gastric acid between treated groups (bamboo salt-, crude salt- and reagent-grade NaCI-treated groups) and control group (distilled water-treated group). This result demonstrated that bamboo salt did not exert anti-ulcer activities in experimental animals used in the present study.

Kalopanax pictus has pharmacologically anti-inflammatory and analgesic effect and is known to respond to treatment of backache, knee pain and etc. In this study, we investigated the effects on gastric lesions of Kalopanax pictus both from Korea (KPK) and China (KPC) compared with their related origin, Znthoxylum ailanthoide both from Korea (ZAK) and China (ZAC), and Korean Bombax malabaricum (BMK). In preliminary screening, KPK and KPC shown effective inhibition of HCI EtOH-induced gastritis in rats. To elucidate their protective effects on gastric lesions, we assessed inhibition of H. pylori colonization, 2,2-diphenyl-1-picrylhydrazyl(DPPH) radical scavenging activities, reducing power test, and inhibition of lipid peroxidation. KPK was the most effective from antioxidant assays. KPK also shown the inhibition of indomethacin-induced gastric ulcer in rats. Gastric secretion in rats, KPK reduced the secretion of gastric juice and total acidity and raised pH. Therefore, it is possible that KPK can be developed as health functional food and natural medicine. In addition, it can contribute to the standardization with objectivity and reliability for KPK through the criteria establishment of the precise origin of medicine, the prevention of indiscriminate distribution of imitation, and the rising rate of dependence on imports of medicinal herbs, and mixing prevention of low-quality goods.
