Objectives : To review the drug prescription pattern of antiulcerative agents for elderly inpatients, Methods : The study population comprised inpatients of community hospitals who were members of the Korean Elderly Pharmacoepidemiologic Cohort (KEPEC), aged 65 years or over, beneficiaries of the Korea Medical Insurance Corporation (KMIC) and residing in Busan city in 1993. The drug prescription information was collected from the claims data of hospitals where the cohort members received medical care between January 1993 and December 1594. The information included personal identification, age, gender, diagnosis, drug dosage, date of hospital admission and name of medical institutions where the study subjects received drug prescriptions. The data analysis produced outcomes in terms of distribution of antiulcerative agents by class and by medical institution and trend of relative prescription, Analysis was also performed in terms of combined prescriptions of antiulceratives and drugs that could induce risk from drug interaction with antiulceratives. Results : The number of patients prescribed antiulcerative agents was 1,059 (64,9%) male and 1,724 (65.5%) female among the total inpatients. An antacid and composite agent was the most frequently prescribed antiulcerative agent (70.8%), followed by $H_2$ antagonist (16.0%), Among the potential drugs that could induce risk from drug interaction with the antiulcerative agents, diazepam was the most frequently prescribed. The proportion of diazepam co-prescription was 22.5% of the total cimetidine prescriptions and 14.5% of the fetal omeprazole prescriptions. Conclusions : Antiulcerative drugs were frequently prescribed in the elderly inpatients. The adverse drug reaction could possibly be due to drug interaction. The study results could be used as fundamental data for further drug utilization review of antiulceratiye agents.

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.

This study was undertaken to investigate the effect of 'Jakyakgamcho-Tang' and parched 'Jakyakgamcho-Tang' on anti-inflammatory and antiulcerative actions, and motility of isolated intestine of mice. The results of this study were summarized as follows; Anti-inflammatory effect was showed markedly by the administration of water extract of 'Jakyakgamcho-Tang' and parched 'Jakyakgamcho-Tang'. Isolated intestine of mice was relaxed with the treatment of 'Jakyakgamcho-Tang' and parched 'Jakyakgamcho-Tang' and intestinal contraction induced by $BaCl_2$ and acetylcholine was also inhibited. The water extract of 'Jakyakgamcho-Tang' and parched 'Jakyakgamcho-Tang' were significantly inhibited Shay's ulceration in rats.

소화기계에 대한 식혜의 생리적 영향을 알아보기 위 한 일환으로 식혜를 섭취 시킨 마우스에 에탄올을 이용하여 위궤양을 유발시켜 식혜의 위궤양 예방효과를 살펴보고자 하였다. 사용된 식혜는 산업화된 시판식혜 및 가정용 식혜의 두 가지였으며 각각 식이에 대해 0.3% 및 3%농도로 첨가하여 45일간 투여하였다. 위궤양에 대한 식혜의 예방효과를 알아보기 위하여 위점막 표면의 pH, 위점액량 및 궤양지수를 측정하였다. 위점막표면 pH는 대조군은 3.4, 식혜투여군은 3.8~3.9의 값을 나타내어 대조군에 비하여 식혜투여군에서 다소 높은 경향을 나타내었으나, 유의한 차이는 관찰되지 않았다(p>0.05). 위점액량과 제양지수에 있어서도 대조군이 556.4$\mu\textrm{g}$ alcian blue/g wet tissue와 18.6mm의 값을 나타낸 반면, 식혜투여군에서는 595.2~673.5$\mu\textrm{g}$ alcian blue/g wet tissue와 13.7~17.8mm의 값을 나타내어 식혜투여군에서 위점액량은 증가되고 궤양지수는 감소되는 경향을 나타내어 식혜의 위궤양 예방효과의 가능성을 시사하였으나, 실험군간의 유의한 차이는 관찰되지 않았다(p>0.05).

In the previous report, it was described that the butanol fraction of the root bark extract of Aralia elata had potent antigastritic and antiulcerative effects in rats, In this pharmacological profile, the fraction revealed low acute toxicities in mice and rats, no central nervous system activities, moderate analgesic action, weak inhibitory action in carrageenin edema of rats and no direct effects on isolated smooth muscles of rats and guinea-pigs. Slight lowering of blood pressure as given i.v. in rabbit was observed.

Gastritis and gastric ulcer were known to be induced by gastic acid, stress, ethanol, Helicobacter pylori and free radical, etc. This study was performed for the development of a new drug or nutraceutical from medicinal plants or natural products with anti-gastritis, anti-ulcerative and gastroprotective activities. The water extract of Scutellaria baicalensis was exhibited potent inhibition in HCl ethanol-induced gastric lesion, acetic acid-induced and Shay ulcers, indicating the effects on gastric lesion and ulcer in rats. The water extract of Scutellaria baicalensis significantly inhibited HCl ethanol-induced gastric lesions at the oral dose of 300, 500 mg/kg. In pylorus ligated rats, the treatments of the water extract from Scutellaria baicalensis showed decrease in the volume of gastric secretion and acid output and increase pH at oral dose of 300, 500 mg/kg. And significantly reduced acetic acid-induced ulcer at the oral dose of 500 mg/kg for 12 days. In this study, we have found that the water extract from Scutellaria baicalensis had significant improvement in acute gastritis and ulcer at the dose of 300, 500 mg/kg and in chronic gastritis and ulcer at the dose of 500 mg/kg. Also we evaluated the antibacterial activity against Helicobacter pylori treated with Scutellaria baicalensis. Scutellaria baicalensis had a equivalent antibacterial activity with ampicilin against H. pylori at the dose of $100\;{\mu}/ml$. In histological examination, the water extract of Scutellaria baicalensis drastically restored gastric damages induced by HCl ethanol solution, pylorus- ligature and acetic acid. Therefore, we may use the water extract from Scutellaria baicalensis as antigastritic and antiulcerative agent for the purpose of the improvement or treatment of gastritis and gastric ulcer.

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.

This study was undertaken to evaluate the gastrotherapeutic effects of the extract of Rosa rugosa. It can be regarded that the antigastric and anti-ulcerative effect of Rosa rugosa is originated from the reduction of total acid output identified by gastric secretion test. To clarify the protective mechanism of the Rosa rugosa extract, the gastropathy was induced in rats with alcohol-salicylate and the activities of the free radical scavenging enzymes were examined. The acitivity of superoxide dismutase and glutathione peroxide were significantly increased and the total content of glutathione was recovered. We concluded that the protective effect of the extract of Rosa rugosa on gastropathy in rats is its ability increased the activities of the free radical scavenging enzymes.
