Although the 'Insamyangwee-tang' has been widely used in clinical purposes in the oriental medicine, its clinical efficacy is only documentated for the cases of gastritis, gastric ulcer and enteritis, but the experimental study on these has not been undertaken. So, to investigate the clinical efficacy of 'Insamyangwee-tang' comparing with animal experiments, This study was carried out. The results showed that relaxing action was shown on the isolated ileum in mice and that strong antagonistic actions were seen on $BaCl_2$, acetylcholine and histamine induced contraction of the ileum in mice, rats, rabbits and guinea-pigs that the relaxing effect of the intestinal smooth muscle was recognized. Inhibitory effects on transport rate in the small intestine of mice. Strong antagonistic actions were seen on acetylcholine induced contraction of duodenum in rats and remarkably inhibiting actions were seen of duodenum in rats. Inhibitory action on the secretion of gastric juice and pepsin, anti-ulceration effect was recognized.

Congenital duodenal obstruction is a one of the emergent surgical conditions in neonates. Almost of them were diagnosed with double-bubble sign in prenatal ultrasonography. However, partial obstruction caused from duodenal web could be overlooked. We reported a duodenal web in early childhood. A three-year-old girl visited at our pediatric clinic for constipation. She had been showed non-bilious vomiting after weaning meal since 6 months old of her age, but her weight was relevant for 50-75 percentile of growth curve. Barium enema was initially checked, but any abnormal finding was not found. We noticed the severely distended stomach and 1st portion of duodenum. Upper gastrointestinal series revealed partial obstruction in 2nd portion of duodenum. After laparotomy, we found the transitional zone of duodenum and identified a duodenal web via duodenotomy. We performed duodeno-duodenostomy without any injury of ampulla of Vater. She was recovered uneventfully. During 6 months after operation, she does well without any gastrointestinal symptoms or signs, such as vomiting or constipation.

In the present paper, the distribution, relative frequences and cell types of endocrine cells in the gastrointestinal tract of the frog (Rana dybowskii) during the hibernating and the active phase were examined by light and electron microscopy. The results obtained are summarized as follow: The reactive cells for Grimelius were frequently found in the gastrointestinal tract, whereas the reactive cells for Hellman-$Hellerstr{\hat{o}}m$ were found numerous in the fundus and pylorus of stomach, a few in the duodenum and lower small intestine, and very few in the rectum during both phases. No reactive cells for Masson-Fontana were found in the gastrointestinal tract during both phases. Elecron microscopically, 4 types of endocrine cells in the fundus of the stomach, 3 types in the pylorus of the stomach and duodenum, and 1 type in the lower small intestine and rectum, respectively, were identified during the hibernating phase. In the active phase, 3 types of endocrine cell in the fundus of the stomach, 2 types in the pylorus of the stomach and duodenum, and 1 type in the lower small intestine and rectum were observed, respectively. In the hibernating phase, more cytoplasmic granules and various types of endocrine cells were generally found than in the active phase.

Having examined the literatures on the terminologies. UlkyuK and Banui, the following results were obtained. 1. since Ul accompanies the symptom of dysphagia. it is thoughr ro indicate the disease and ailment in the larynx and pharynx. and the esphangus. 2. Kuyk is used in the contextof Kyuksak. Kyukjung. Bikyuk. Ulsakamnd Ulkyuk. and since it also includes the meaning of Ul. it is thought that disease and ailment in the esophagus. stomach and duodenum are included in this category. 3. Although Ul and Kyuk are differentiated. since they appear in conjunction with the other clinically. they can be refferred to as Ulkyuk. 4. Banui represents the phenomenon of vomiting. because it is oresent in a bad case of Ulkyuk. it can be seen to be included in Ulkyuk. Thus. Ulkyuk and Banui can be refferred to as one. 5.Although the name of an ailments in oriental medicine and that in the western medicine can not be in perfect match. Ulkyuk is refferred to as ailments in esophagus such as esophagitis. esophageal ulcer, esophageal deverticulum and esophageal cancer. while Banui is refferred to asailments in stomanch and duodenum such as stomach cancer. chtonic spasmic gastritis. it is reasonable to differentiate the two in general. As seen above, since the concept of the terminologies. Ulkyuk and Banui are somewhat different among Oriental medicine doctors. a consensus is needed to come up with terms that all can agree on.

Recently, the researches on the enteroendocrine cells of vertebrates have made a remarkable advance by the immunocytochemical methods. This study was attempted to investigate the topographical distributions and the shapes of gastrin, glucagon, somatostatin and cholecystokinin-8 immuno-reactive cells in the gastrointestinal tract of the Korean hedgehog, Erinaceus koreanus. For light-microscopical examination of immunocytochemistry, the tissue specimens taken from the various portions(body and pyloric protion of stomach, duodenum, jejunum, ileum and rectum) were fixed in glutaraldehyde-picric acid-acetic acid (GPA) or 10% neutral buffered formalin solutions. For the demonstration of immunoreactive cells, the paraffin sections (6$\mu$m) were immunocytochemically identified by PAP procedure (Sternberger, 1979) with gastrin, glucagon, somatostatin and cholecystokinin-8 antisera. Gastrin-immunoreactive cells were mainly distributed in the pyloric portion of stomach and were a few in the duodenum and jejunum. The shapes of these cells were round or oval in the pyloric portion and pyramidal in the small intestine. Glucagon-immunoreactive cells were sparsely distributed in the only small intestine. The shapes of these cells were mainly pyramidal. Somatostatin-immunoreactive cells were a few in the pyloric portion and duodenum, and were sparsely distributed in the body of stomach and jejunum. The shapes of these cells were round or oval in the stomach and oval or pyramidal in the small intestine. Cholecystokinin-8-immunoreactive cells were sparsely distributed in the only small intestine. The shapes of these cells were mainly oval or pyramidal.

In 1944 Cavallito and Bailey first extracted an essential oil, a powerful antibacterial principle, from the garlic and named it allicin. Later Stoll and Seeback elucidated that allicin was produced from alliin by the enzymatic action of arinase. Damaru observed the depressor responses following intraperitoneal administration of garlic juice in cats. And Thiersch presented evidence that garlic had a protective action against experimental arterosclerosis in cholesterol-fed animals. On the other hand it was also reported that anemias were caused by long-term ingestion of garlic as a result of reduction in hemoglobin and RBC. From the experiment in which the effect of garlic on the blood sugar level was studied, Lee insisted garlic elevated blood sugar level. However, August and Jain claimed that hypoglycemia was induced by garlic administration. Recently Bordia and Bansal suggested that essential oils extracted from onion and garlic have a strong preventive effect on hyperlipemia and prolonged coagulation time resulted from fat-feeding. Furthermore Bordia et al indicated that garlic exerted a strong fibrinolytic activity. In early 1920 s Sugihara reported that essential oil of garlic not only decreased arterial blood pressure but also had a paralytic effect on the isolated heart and intestinal strip of animals. The present study was proposed to investigate the effect of garlic juice and the mechanism of its action on the motility of the isolated rabbit duodenum. The motility of the isolated duodenum was recorded on polygraph by means of force transducer connected with Magnus apparatus. And the isolated duodenum was separtely pretreated with $acetylcholine(5{\times}10^{-7}\;gm/ml)$, $pilocarpine(2.5{\times}10^{-6}\;gm/ml)$, $histamine(5{\times}10^{-6}\;gm/ml)$ and barium $chloride(2.5{\times}10^{-5}\;gm/ml)$ in order to find out interations of these drugs with ASJ. The results obtained were as follows; At concentrations of 0.25%, 0.5% and 1.0% ASJ markedly inhibited contractions of isolated duodenum while tonus as well as contractility of the isolated intestine were decreased also with 0.5% and 1.0% ASJ. Since ASJ markedly abolished augmented motility of isolated intestine by histamine and partly reduced that by $BaCl_2$, it is strongly suggested that inhibitory action of ASJ on the intestinal motility is caused mainly by its antihistamine effect and partly by its direct action on the intestinal smooth muscle.

Iron (Fe) is an essential metal in biological processes, which maintains a homeostasis in the human body. Divalent metal transporter 1 (DMT1) has been known as an iron transporting membrane protein, which is involved in the uptake Fe at the apical portion of intestinal epithelium, and may transport Fe across the membrane of acidified endosome in peripheral tissues. In this study, we studied the tissue distribution of DMT1 in the Fe supplemented (FeS) diet fed rats, and the regulation of DMT1 expression by depleting body Fe. Sprague-Dawley rats were divided into two groups, and fed FeS (120 mg Fe/kg) diet or Fe deficient (FeD, 2∼6 mg Fe/kg) diet for 4 weeks. The evaluation of body Fe status was monitored by measuring sFe, UIBC and tissue Fe concentration. Additionally, DMT1 mRNA levels were analyzed in the peripheral tissues by using the quantitative real time RT-PCR method. In the FeS diet fed rats, the tissue Fe was maintained at a relatively high level, and DMT1 was eventually expressed in all tissues studied. DMT1 was highly expressed in the testis, kidney and spleen, while a moderate levels of DMT1 expression was detected in the brain, liver and heart. In the digestive system, the highest level of DMT1 was found in the duodenum. Feeding the FeD diet caused a reduced body weight gain and depletion of body Fe with finding of decreased sFe, increased UIBC and decreased tissue Fe concentration. The depletion of body Fe upregulated DMT1 expression in the peripheral tissue. The expression of DMT1 was very sensitive to the body Fe depletion in the small intestine, especially in the duodenum, showing dramatically higher levels in the FeD rats than those of the FeS group. In the FeD diet fed animals, the expression of DMT1 was low significantly in other tissues compared with the duodenum. The expression of DMT1, however, was 60∼120% higher in the testis, kidney and spleen, and 30∼50% higher in the lung, liver and heart, compared to the FeS diet fed rats. In summary, DMT1 expression was ubiquitous in mammalian tissue, and the level of expression was the organ-dependent. The expression of DMT1 in peripheral tissues was upregulated by depletion of body Fe. Duodenum was the most sensitive tissue among organs studied during Fe depletion, and expressed the greatest level of DMT1, while other tissues were less higher than in duodenum. This study supports that DMT1 plays a role in maintaining the body Fe level through intestinal uptake as well as homeostasis of Fe in the peripheral tissue.
