  • Endoscopic resection is now accepted as curative treatment modalities for early gastric cancer without lymph node metastasis. However, based on large-scaled data about the risk of lymph node metastasis in early gastric cancer and as a result of the technical development of endoscopic devices, it was suggested that the criteria for endoscopic resection should be extended. According to the treatment guidelines for gastric cancer in Japan, the extended indications include the following: differentiated-type mucosal cancer without ulceration and greater than 2 cm in diameter, differentiated-type mucosal cancer with ulceration and up to 3 cm in diameter, undifferentiated-type mucosal cancer without ulceration and up to 2 cm in diameter, and, in the absence of lymphovascular invasion, a tumor not deeper than submucosal level 1 (less than $500\;{\mu}m$). In this review, we discuss the evidence of the application of expanded endoscopic indication based on analysis of biologic behavior and data of endoscopic resection.

  • The lastest date, increasing H. pylori infected gastric ulceration is indispensible with treatment of Herb medicines. Because the lesser side and the more cure rate are necessary on clinical treatment. Thus, recently herd medicines of Chinese medical treatment exhibit the method of prescription. Therefore, I think the various prescription will be applied to H. pylori infected gastric ulceration on foward.

  • Frequently used for humans as a nonsteroidal anti-inflammatory drug, naproxen has been known to induce ulcerative gastric lesions. The present study was undertaken to investigate the in vivo therapeutic effect of astaxanthin, isolated from a Xanthophyllomyces dendrorhous mutant, against naproxen-induced gastric antral ulceration in rats. The rats were treated with three doses of astaxanthin [1, 5, and 25 mg/kg body weight (B.W.), respectively] once daily for 2 weeks after pretreatment of 80 mg of naproxen/kg B.W. twice daily for 3 days, while the control rats received only 80 mg of naproxen/kg B.W. twice daily for 3 days. The oral administration of astaxanthin (1,5, and 25 mg/kg B.W.) showed a curative effect against naproxen (80 mg/kg B.W.)-induced gastric antral ulcer and reduced the elevated lipid peroxide level in gastric mucosa. In addition, astaxanthin treatment resulted in significant increase in the activities of radical scavenging enzymes such as superoxide dismutase, catalase, and glutathione peroxidase. A histologic examination clearly proved that acute gastric mucosal lesion induced by naproxen nearly disappeared after the astaxanthin treatment. These results suggest that astaxanthin eliminated the lipid peroxides and free radicals induced by naproxen and may be a potential candidate for remedy of gastric ulceration.

  • In a preliminary screening of the plant extracts for the antigastritic action in rats, the extract of Aralia elata(Araliaceae) showed positive activity in HCI plus ethanol induced gastric lesion. Systematic fractions with hexane, chloroform, ethyl acetate and butanol resulted in the most patent activity with the butanol fraction: This butanol fraction at the oral dose of 200 mg/kg exhibited significant inhibition of absolute alcohol induced gastric lesion which was more potent than 100 mg/kg of cimetidine and had significant stimulation of mucus secretion. The butanol fraction showed significant decreases in the ulcer indices of Shay ulcers and inhibition of gastric juice secretion with acid output in pylorus-ligated stomachs of rats. It also suppressed the acetic acid induced gastric ulcer. These results might suggest that the butanol fraction had inhibitory action in gastric lesion and ulceration through inhibition of gastric acid secretion and stimulation of mucin secretion in the stomachs of rats.

  • The bark of Ulmus davidiana var. japonica(Ulmaceae) has been described in traditional books to have diuretic and laxative actions, to ameliorate edematous disease, and to be used in insomnia and gastointestinal disorders. Thus this study was carried out to elucidate some of the pharmacological activities of the plant extracts. The results obtained in tills experiment indicated that its methanol extract elicited remarkable inhibition of HCI.ethanol induced gastric lesion, Shay ulceration and gastric secretion. However, it showed no anti-inflammatory action. The acute toxicity of the extract was low, that is, the minimum lethal dose was more than 2000 mg/kg by oral administration in mice. The systematic fractionation of the methanol extract by hexane, ether, ethylacetate and butanol resulted in potent prevention of gastric erosion in butanol and water fractions.

  • Secondary peptic ulceration and gastritis have been known to be associated with stress, exogenous agents, drugs or infection. Salicylate (aspirin) ingestion has been known to be associated with increased incidence of gastric ulcer and more frequently as the cause of hemorrhagic gastric erosions and gastritis. Some medications such as tetracyclines and iron preparations have been associated with ulceration of the gastrointestinal tract. Chemotherapeutic agents including cytoxan and methotrexate also have been implicated in the development of mucosal and gastrointestinal ulcers. We have experienced two cases of hemorrhagic gastric ulcers due to creosote ingestion in a 13 month and a 5 year old boys. Creosote is a main component of one of the popular digestives, Jungrohwan in Japan and Korea.

  • 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.

  • Gastric tuberculosis is rare even in the endemic areas of tuberculosis, and can mimic neoplasm by causing elevation of the mucosa with or without ulceration. Here, we report a case in which a 54-year-old female patient admitted for resection of early gastric cancer was found to have coexisting histopathologically and bacteriologically confirmed gastric cancer and tuberculosis.

  • The protective effect of adenosine triphosphate (ATP) on gastic ulcer induced in rats has been studied. Gastic ulceration was induced by hypothemic restraint stress or dicolofenac sodium. Gastic acid secretion and mucosal injury produced by the hypothemic restraint stress was greater as compared with those produced by diclofenac sodifum. ATP significantly reduced area of injury, however, increased cyclic adenosine monophosphate (cATP) content. Administration of dipyridamole along with ATP did not change the total lesion area in both models when compared to ATP alone. Aminophyline antagonized antagonized the protective effect of ATP on the injured area. Famotidine was found to be effective in reducing gastric acid output as well as the total injured area without any change in cAMP content when given along with ATP.

  • Gastroprotective effects of Korean rice-wine (Yakju) in two types of acute experimental gastric ulcer induced in rats and in mice were evaluated. Korean rice-wine were administered to 24-hr fasted rats 30 min before administration of 60% EtOH in 150 mM HCl or absolute ethanol. Korean rice-wine prevented formation of gastric ulcers induced by 60% EtOH in 150 mM HCl at oral doses of 250-1,000mg/kg and reduced gastric ulcers induced by absolute ethanol at oral doses of 62.5-1,000mg/kg, and inhibitory effect against 30% alcohol treatment for 7 days (twice/day). These results suggest Korean rice-wine have inhibitory effects on gastric lesion and ulceration.
