Alnus japonica cortex has been used as antidiarrhea, antihemorrhage and the remedy of indigestion. This study was performed to investigate the effectiveness of the methanol extracts of the Alnus japonica cortex on the gastric lesion and ulcer. The methanol extract was fractionated with hexane, chloroform and butanol, followed by bioassay on antigastritic and antiulcer activity. The methanol extract showed low acute toxicity with minimum lethal dose of more than 5000 mg/kg, p.o. in mice. The chloroform and the butanol fraction reduced gastric lesion in HCI. ethanol induced gastritic model. On gastric secretion in pylorus ligated rat, the hexane and chloroform fraction decreased the volume and acidity. The butanol fraction had significant inhibitory effects on aspirin and Shay's ulcer. The butanol fraction showed a tendency to inhibit the decrease of mucin secretion due to ingestion of absolute ethanol.

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.

From our previous result that Panax ginseng head extract had inhibition of gastric damages, the extract was fractionated. Among the hexane, chloroform, butanol and water fractions, butanol fraction Showed the most potent inhibition of HCl.ethanol-induced gastric lesion, aspirin-induced gastric ulcer, acetic acid-induced ulcer and Shay ulcer. Butanol fraction showed significant increase in mucin secretion, and inhibited malondialdehyde (MDA) and $H^{+}/K^{+}ATPase$ activity in the stomach. This results indicate that the effectiveness of the fraction on gastric damages might be related to inhibition of acid secretion, increment of mucin secretion and antioxidant property.

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.

This study was attempted to investigate the effect of Ganoderma lucidum extract on digestive system in experimental animals. Ganoderma lucidum water extract (GWE) was found to be promoted the charcol transport rate in the small intestine of mice. GWE exhibited the augmentation of spontaneus movement(motility) and contractile response(tension) in the ileum and colon strips of rabbit, and these action were inhibited by atropine. GWE given intraduodenaly(i.d.) exhibited the significant increase of gastric acid secretion in pylorus-ligated rats. GWE inhibited the formation of some experimental gastric ulcers(pylorus ligation ulcer i.d., indomethacin-induced ulcer p.o., i.d. and aspirin-induced ulcer p.o.) in rats, which are considered to relate to a protective action. GWE and EtOH extract(water soluble phase) were remarkably increase of bile excretion, when administration of i.d., intravenation(i.v.) and per os (p.o.) compared with normal-control group. GWE was observed antibacterial activity aginst several intestinal microoganisms and others bacteria in vitro test.

This study was attempted to investigate the effect of Machili Cortex extract(Machilus thunbergii Sieb. et Zucc. ) on digestive system in experimental animals. EtOH and MeOH extracts(E.E. and M.E.) were found to inhibit the charcoal transport rate in the small intestine of mice. E.E. exhibited the inhibition of spontaneous movement(motility) and tension in the ileum and colon strips of rabbit, and these actions were inhibited by action of acetylcholine. E.E. and M.E. given intraduodenaly(i.d.) exhibitied the significant decrease of gastric acid secretion in pylorus-ligated rats. E.E. and M.E. inhibited the formation of some experimental gastric ulcers(pylorus ligation-ulcer i.d., indomethacin-induced ulcer p.o. and aspirin-induced ulcer p.o. ) in rats, which are considered to relate to a protective action. E.E. and M.E. caused remarkable increase of bile excretion, compared with normal-control group, when adminstered through i.d., i.v. and p.o. The antibacterial activity against several intestinal microorganisms and other bacteria in vitro test was observed in the administration of E.E. and M.E.
