The experimental study used in this paper was done to examine the clinical effects of Taeumchowetang for the gastric ulcer and the function of gastrointestinal tract using rats and mice which were administered orally the water extraction from Taeumchowetang. Then, the counter-action of the water extraction on the isolated ileum and gastric fundus, the inhibitory effects of pylorus-ligated ulcer and indomethacin-induced ulcer, the associations with gastric juice secretion, total acidity, pepsin output, the transportability in the small and large intestine, were studied with administering acetylcholine chloride and barium chloride. In addition, it was investigated whether the central nervous system related to pain control and sleeping time was influenced by Taeumchowetang. The following results have been obtained; 1. As resulting from injection of acetylcholine chloride and barium chloride into the isolated ileum of rats and mice, Taeumchowetang led to have an inhibitory effect on the muscle contraction of the ileum. Then, acetylcholine chloride was measured as lower effect than barium chloride 2. For the inhibitory effect on contraction for the gastric fundus strip in rats by either acetylcholine chloride or barium chloride, the one showed low inhibitory effect, on the other hand the other showed density-dependent effect. 3. The water extraction was given on the pylorus ligated ulcer with using two different administration groups of 1,300mg/kg and 2,600mg/kg, each result was measured as 22.9% and 36.5% for an ulcerous inhibitory effect (p<0.05). 4. According to the two administration groups, the preventive effect was tabulated 18.1% and 29.3% for indomethacin-induced ulcer (p<0.05, P<0.01). 5. For associations with gastric juice secretion, total acidity, pepsin output in the administration group 2,600mg/kg, Taeumchowetang was recognized as having an inhibitory effects related to suppressive actions involving gastric juice secretion(p<0.05), and free acidity(p<0.01), but there was no significant association with total acidity and pepsin output. 6. To know the transportability in the intestine, BaSO4 solution was used. The transportability of the small intestine in the administration group 2,600mg/kg was 22.2% which was statistically significant compared with the large intestine's transportability(P<0.01). 7. In the administration group 1,300mg/kg and 2,600mg/kg, analgesic effect with against acetic acid was measured as being 16.8% and 24.4% which was shown as statistically siginificant(p<0.01). 8. No statistically significant association between Taeumchowetang and sleeping time was found in both 1,300mg/kg and 2,600mg/kg by administering phenobarbital-Na. According to the results of this study, Taeumchowetang has agreed with the effects of literature review. Further more in this study, Taeumchowetang also has preventive effects on pylorus-ligated ulcer. Hence, Teaumchowetang can be significant effect such as both anti ulcer agent and increasing gastric activity for the patients who suffer from gastric ulcer.

Glucose tolerance, insulin and growth hormone responses following glucose or amino acids administration by means of parenteral or oral load were studied in patients with far advanced gastric cancer. Hormone responses following nutrients load showed in patients with gastric cancer were compared to those of healthy subjects. Results were as follows: 1. Blood sugar appearance following oral glucose administration was diminished in patients with far advanced gastric cancer. 2. The insulin responses of gastric cancer following oral glucose were also diminished as compared to that of normal subjects and were identical with parenteral route. 3. Parenteral administration of glucose or amino acids to patients with gastric cancer result ed in a increase of plasma growth hormone level. 4. Lower insulin response to amino acids was observed on parenteral administration in patient with gastric cancer as in healthy subjects. 5. Author discussed that the low insulin response after oral glucose administration showed in gastric cancer, and any additional insulin requirement arise when longer periods of parenteral amino acid administration are necessary, as in the patient with malnutritions.

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.

We generated gene expression data from the tissues of 50 gastric cancer patients, and applied meta-analysis and gene set analysis to this data and three other stomach cancer gene expression data sets to define the gene expression changes in gastric tumors. By meta-analysis we identified genes consistently changed in gastric carcinomas, while gene set analysis revealed consistently changed biological themes. Genes and gene sets involved in digestion, fatty acid metabolism, and ion transport were consistently down-regulated in gastric carcinomas, while those involved in cellular proliferation, cell cycle, and DNA replication were consistently up-regulated. We also found significant differences between the genes and gene sets expressed in diffuse and intestinal type gastric carcinoma. By gene set analysis of cytogenetic bands, we identified many chromosomal regions with possible gross chromosomal changes (amplifications or deletions). Similar analysis of transcription factor binding sites (TFBSs), revealed transcription factors that may have caused the observed gene expression changes in gastric carcinomas, and we confirmed the overexpression of one of these, E2F1, in many gastric carcinomas by tissue array and immunohistochemistry. We have incorporated the results of our meta- and gene set analyses into a web accessible database (http://human-genome.kribb.re.kr/stomach/).

Forty species of lactic acid bacteria isolated from gajami sikhae were identified as Lactobacillus plantarum, Leuconostoc mesenteroides, Lactobacillus brevis, and Weissella paramesenteroides. 10 of the 40 strains were selected and used for the test. In this study, experiments such as those using acid and artificial gastric juice resistance, bile acid resistance, autoaggregation, coaggregation, and cell surface hydrophobicity were conducted to utilize lactic acid bacteria separated from gajami sikhae as probiotics. The separated lactic acid strains showed high survival rates through displaying resistance to acidic and artificial gastric juices; L. plantarum GS11 showed the best resistance. Also, as a result of a measurement of bile acid resistance, all lactic acid bacteria stocks showed survival of more than 100% with a probiotic number of 10⁸ to 10⁹ log CFU/ml. After evaluating cohesion to indirectly measure cell surface adhesion, autoaggregation ability was shown to be more than 46%. Measurement of xylene adhesion for cell surface hydrophobicity evaluation revealed better cell adhesion than B. subtilis, which has 32.2% hydrophobicity in isolated lactic acid strains. Antibacterial force measurement found antibacterial activity in lactic acid bacteria, excluding L. plantarum GS12 and L. plantarum GS13. Therefore, it was judged that lactic acid bacteria separated from gajami sikhae could be used as probiotics with various probiotic properties.

The present paper describes temporal changes of immunohistochemical localization and quantities of carbonic anhydrase isozyme II (CA-II) prochymosin (PC) and pepsinogen (PN) in goat's abomasal mucosae during long term milk feeding. The CA-II was not detected by day 14 after birth and then became positive on day 34 in the parietal cells, suggesting that the excretion of the hydrochloric acid (HCl) begins between days 14 and 34 under a feeding condition without solid materials. The quantity of the PC in the gastric chief cells detected by the ELISA showed rapid increase from the day of birth, making a peak on day 8 and then gradually decreased with age. The decrease in quantity of PC became started during the time period when HCl excretion had not started yet. The quantities of PN in the gastric chief cells were almost stable during the whole period examined. Expressions of these gastric enzymes did not seem to be regulated by the change of feeding condition.

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.

A new series of highly water soluble platinum(II) complexes[Pt(II)(DL-2-hydroxy-3-methylbutyrate)(trans-l-1,2-dimninocyc1ohexane)] (PC-1) and [Pt(II)DL-2-hydroxy-3-methylbutyrate](cis-1,2-diaminocyclohexane)](PC-2) were synthesized and characterized by their elemental analysis and by various spectroscopic techniques [infrared(IR), $^{13}C$-nuclear magnetic resonance (NMR)]. In vitro antitumor activity of new Pt(II)complexes was tested against MKN-45, MKN/ADM and MKN/CDDP human gastric adenocarcinoma cell lines using colorimetric MTT[3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyltetrazoliumbromide] assay for cell survival and proliferation. PC-1 and PC-2 showed active against MKN-45/P, MKN/ADM and MKN/CDDP human gastric cancer cell lines, and the antitumor activity of these compounds were comparable or superior to that of cisplatin. The nephrotoxicities of PC-1 and PC-2 were found quite less then that of cisplatin using MTT and [$^3H$] thymidine uptake tests in rabbit proximal tubule cells, human kidney cortical cells human renal cortical tissues. Based on these results, these novel platinum(II) complex compounds(PC-1 ＆ PC-2) represent a valuable lead in the development of the new anticancer chemotherapeutic agents capable of improving antitumor activity and low nephrotoxicity.

A gastroduodenostomy is the most physiological reconstruction after a distal gastrectomy. However, a gastroduodenostomy with either sutures or staples has many complications. These include bleeding, leakage and stenosis. A sutureless gastroduodenostomy with a biofragmentable anastomosis ring (BAR) in was used adenocarcinoma patients to prevent these complications from 1999. A BAR is composed of polyglycolic acid and Barium sulfate to allow for X-ray visualization. Hardy in first introduced the BAR in 1985. Since then, it has been used in an anastomosis of the colon or small bowel surgery but its use in a gastroduodenostomy is the first trial in the world. A 70 year male patient, old who received a subtotal gastrectomy (Billroth I), underwent a A sutureless gastroduodenostomy with a BAR. The gastroduodenostomy with the BAR was watertight and maintained the initial burst strength in the gastrografin X-ray study performed at the postoperative 1 week. The BAR began to fragment 3 weeks after the operation and disappeared from the digestive tract completely. The diameter of the anastomosis site was sufficient for passed foods. No other secondary changes from remained foreign bodies were found in the endoscopic examination. In a second operation to treat a primary hepatoma, there was no adhesive changes around the gastroduodenostomy site. In conclusion, a sutureless gastroduodenostomy with BAR is a safe, easy and efficient reconstructive method after a distal gastrectomy.
