  • Background: Helicobacter pylori (H. pylori) remains an important cause of gastric cancer and peptic ulcer disease worldwide. Treatment of H. pylori infection is one of the effective ways to prevent gastric cancer. However, standard triple therapy for H. pylori eradication is no longer effective in many countries, including Thailand. This study was designed to evaluate the efficacy of adding bismuth and probiotic to standard triple therapy for H. pylori eradication. Materials and Methods: In this prospective single center study, H. pylori infected gastritis patients were randomized to receive 7- or 14-day standard triple therapy plus bismuth with probiotic or placebo. Treatment regimen consisted of 30 mg lansoprazole twice daily, 1 g amoxicillin twice daily, 1 g clarithromycin MR once daily and 1,048mg bismuth subsalicylate twice daily. Probiotic bacteria composed of Bifidobacterium lactis, Lactobacillus acidophilus and Lactobacillus paracasei. Placebo was conventional drinking yogurt without probiotic. CYP2C19 genotyping and antibiotic susceptibility tests were also done. H pylori eradication was defined as a negative $^{13}C$-urea breath test at least 2 weeks after completion of treatment. Results: One hundred subjects were enrolled (25 each to 7- and 14-day regimens with probiotic or placebo). Antibiotic susceptibility tests showed 36.7% metronidazole and 1.1% clarithromycin resistance. CYP2C19 genotyping revealed 40.8%, 49% and 10.2% were rapid, intermediate and poor metabolizers, respectively. The eradication rates of 7- or 14 regimens with probiotics were 100%. Regarding adverse events, the incidence of bitter taste was significantly lower in the 7- day regimen with the probiotic group compared with 7- day regimen with placebo (40% vs. 64%; p=0.04). Conclusions: The 7-day standard triple therapy plus bismuth and probiotic can provide an excellent cure rate of H. pylori (100%) in areas with low clarithromycin resistance such as Thailand, regardless of CYP2C19 genotype. Adding a probiotic also reduced treatment-related adverse events.

  • Fifty strains of mold which isolated from the various sources were screened for the production of Naringinase which hydrolyse naringin, the 7-rhamnoe-glucoside of 4'.5.7. - trihydroxyflavanonin, the main bitter principle of citrus fruits and grape fruits. Of the 4 strains yielded naringinase with significant activity, S-1 strain was selected on the criterion of industrial application, and some properties of crude naringinase of this S-1 was investigated. The results obtained were as follows. 1. Naringenase obtained from S-1 strain has optimum pH range from 3.0 to 5.0 for its activity. 2. Production of naringinase was increased on the addition of naringin to the medium. 3. Hydrolysis of naringin with approporiate concentration of naringinase was carried out linerly up to 80% on the 0.1% substrate solution. 4. The optimum temperature for its activity was $50^{\circ}C$, and this enzyme was inactivated 80% of its total activity at $70^{\circ}C$ for 10 minutes, 40% at $60^{\circ}C$ for 30 minutes. But signifiant decrease of activity were not occurred by heat treatment at $50^{\circ}C$ for 2 hours. 5. Crude enzyme of the naringinase obtained from S-1 strain was competitively inhibited by addition of glucose on the substrate, and inhibitor constant of the glucose on the this enzyme was 1.5 Mol, and inhibition rate were linearly increased according to the increase of sucrose concentration and 56% of its total activity was inhibited at 1 Mol sucrose solution.

  • Limonoids are abundant as bitter taste in citrus fruit and other plants. Interestingly. limonoid UDP-glucosyltransferase (LUGT) effectively ameliorates the bitterness from limonoid. The high level of LUGT expression in Escherichia coli can result in the formation of insoluble aggregates known as inclusion bodies. We isolated the soluble LUGT protein when this inclusion body was renaturated with ${\beta}$-cyclidextrin treatment after protein denaturation by urea. Our present results suggest that the isolation of LUGT from inclusion body in cells leads to shed light to characterize the enzyme for food industry purposes.

  • To develop a new functional kimchi with cognition-enhancing properties, black Panax ginseng extract (0.5-5%, w/w) was added to a baechu kimchi preparation and the mixture stored at $4^{\circ}C$ for 30 days. Compared with control kimchi, the L values of ginseng-treated material were significantly decreased, but the a and b values were increased. The hardness value of ginseng-treated kimchi was significantly higher than that of control material from the $20^{th}$ day of storage. The edibility period of baechu kimchi treated with ginseng was prolonged by approximately 15 days compared with control kimchi. This resulted from decreases in the numbers of lactic acid bacteria and yeasts during the final stages of fermentation in ginseng-treated material. Inhibition of acetylcholinesterase activity by ginseng-treated kimchi was 2-fold higher than that of control material. A strong ginseng flavor and a bitter taste were evident in kimchi treated with 5% (w/w) ginseng, and sensory quality was thus decreased compared with control material. It was concluded that an appropriate concentration of black ginseng extract was 3% (w/w) in preparation of kimchi with a cognition-enhancing effect.

  • This study investigated the quality characteristics of red ginseng extracts prepared using alkaline water. The principal extract mineral was calcium, at 61.73-180.63 mg%, and alkalinity increased as the ionization minerals concentration rose. Alkaline red ginseng extracts(AKRGEs) 3, 6, and 9 were found to have pH values of 4.9-5.0, to be of 3.03-3.43 degrees of $^{\circ}Brix$, with soluble solid contents of 2.33-2.60%(w/v). Extract 3 was brown in color, thus similar to that of(conventional) red ginseng extract(RGE). The calcium contents and alkalinity levels of AKRGE 6 and AKRGE 9 were approximately 18-29-fold and 5-11-fold higher, respectively, than those of RGE and five commercial samples of red ginseng. AKRGEs showed lower crude saponin contents than did RGE, but ginsenoside contents did not differ significantly between RGE and AKRGEs. The DPPH-assayed free-radical and superoxide radical scavenging activities of AKRGEs were 12-13% and about 20%, respectively, thus similar to those of RGE. In sensory evaluation tests, AKRGE 3 and 6 were less bitter and better in overall quality than was RGE.

  • Cooking characteristics of coated rice with water homogenate of citrus fruit peels (1% for rice) were investigated. The color of the coated rice both before and after cooking was dark yellow. The total content of carotenoids, hesperidin and naringin were 10.74, 2173.12 and 1468.40 mg% for citrus fruit peels, 0.46, 108.65 and 73.35 % for its water homogenate, 0.12, 21.73 and 14.62 mg% for coated rin, and 0.05, 8.67 and 5.87 mg% fur cooked coated rice, respectively. Citrus fruits peel contained 94.22 mg% of asparagine, 24.88 mg% of methionine, 19.64 mg% of alanine, and 15.37 mg% of ${\gamma}$-aminoisobutyric acid as the majority free amino acids, accounting for 70% of the total free amino acids present. Total free amino acid content of the cooked coated rice increased by 15% compared to those of cooked uncoated rice. The majority of minerals in the citrus fruit peels were K and Ca, accounting for 56% of total minerals present. The mineral content of cooked coated rice was generally higher than that of the cooked uncoated rice. The cooked coated rice showed comparable hardness, gumminess and brittleness, but higher cohesiveness and springiness than the cooked uncoated rice. There were no differences in sweet and bitter taste between the cooked uncoated and coated rice. However, the cooked coated rice showed higher sensory scores fur color acceptability, savory taste and overall acceptability than the cooked uncoated rice.

  • AS a part of investigation to use anchovy more effectively as food source, this work was undertaken the processing conditions of extracts from rapid fermented anchovy sauce. To prepare rapid fermented products, the chopped anchovy was mixed with 50% water (w/w), and then hydrolyzed by autolysis or addition of koji under different conditions of hydrolysis. The optimal conditions for hydrolysis of chopped anchovy were revealed $50^{\circ}C$, 6 hours, pH 8.0 by autolysis, and ,$50^{\circ}C$, 6 hours, pH 7.0 by addition of 10% koji, respectively. But, pH control was not much beneficial in increasing yield. The effect of soybean protein isolote for improvement of bitter taste was also tested. The reasonable amount of added soybean protein isolate was revealed 5% on the weight basis of the chopped anchovy. The reaction mixture hydrolyzed under optimal conditions were added with 1% onion powder (w/w), 1% garlic powder(w/w) and 1% red pepper powder(w/w) for masking fishy odor, inactivated for 20 min at $100^{\circ}C$, and then centrifuged for 20 min at 4,000 rpm. The supernatant liquor was filtrated and evaporated to 50%(v/v). finally, table salt was added for bateriostatic effect and characteristic taste of rapid fermented products. the reasonable amount of added table salt was reversed 15% on the volume basis of the evaporated liquor. The hydrolysis ratio of product made by addition of water, product made by addition of koji and water, and product made by addition of soybean protein isolate, koji and water hydrolyzed under optimal conditions were 58.4%, 82.1% and 86.2%, respectively.

  • Objectives : Radix Bupleuri is from the dried root of the herb of the Perennial herbaceous plant, Bulpleurum falcatum L. or Bulpleurum chinense DC. or Bulpleurum. scorzonerifolium Willd., family Umbelliferae. Medicinal Properties are bitter and pungent in flavor, slightly cold in nature and attributed to the liver and gallbladder meridians. Actions in modern Materia Medica are regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking. The ‘uplift yang-qi to raise sinking’ efficacy, out of three efficacies (regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking), has been disputed in the medical profession for a long period. Hereupon, this study ascertained the reason why it has been disputed. Methods : With respect to this medicinal herb, the efficacies of regulate the functional relation of internal organs to relieve fever, disperse the stagnated liver-qi and uplift yang-qi to raise sinking were described as to what was written in ‘Shen Nong's Herbal’ from Chin and Han dynasties until Jin and Yuan dynasties. Results : The beginning of Jin and Yuan dynasties, it began to deal with the ‘uplift yang-qi to raise sinking’ efficacy and so it has been carried on modern textbooks and medical books. The reason why it was added is that it was influenced by the theory of ‘Raise Sinking’ advocated by Zhang jieku who lived in the period of Jin and Yuan dynasties. Since then, the properties of ‘Radix Bupleuri’ have been wrongly known to the public. Additionally, ‘Radix Stellariae Seu Gypsophilae’, which was begun to be introduced from the Four Cities since the Five Dynasties, has been combined with the best stuffs of ‘Radix Bupleuri’ produced from Yin Zhou. Consequently, its original properties were remarkably disordered. Likewise, respective medical schools’ theories were changed by the influence of ‘Bulpleurum. scorzonerifolium Willd’ begun to be used since Tang dynasty. Conclusion : it is considered that the current ‘Raise Sinking’ efficacy of Radix Bupleuri is unreasonable to be applied to the efficacy of the whole Radix Bupleuri because it is limited to certain species.

  • This study has been done in order to help the people understand the cancer patients and provide the basic materials for the care of cancer patients by deeply understanding the living experience of the practice of alternative therapy for cancer patients. Data were collected with several in depth interviews and observations. Collected datas were analyzed by using phenomenological method of study by Giorgi (1970). The trial experience of alternative therapy for cancer patients has been classified into the one of having concerns, following, being infatuated, and coming out by pushing, and the experience of having concerns appeared as the meaning of the limit of modern medicine, despair, loneliness. hope, emotional support. dissolution of the feeling of uneasiness. the feeling of burden of the medical expense, self-treating, the subject of treatment. and indifference while the experience of following appeared as the meaning of blind following, temptation, going outside to look for something, wandering. following unconditionally, advise of the professionals, mistaken belief. self-abandonment, powerlessness. disconnection of dialogue with the medical staff. elevation of immunity, strengthening the physical power, absence of the source of examined information, clinging, self-responsibility. the experience of being infatuated appeared as the meaning of thorough trial. affirmative experience. devotion. diverse efforts, faithful trial. affirmative self-suggestion. change of the style of life. the feeling of burden of expense, being envious, bitter feeling toward the family, considering family, family discords, and difficulty of enforcement. The experience of coming out by pushing appeared as the meaning of waiting. self-reflection. maintaining the distance. cutting attachment, throwing the greed away, coming out by pushing. being thoughtful. accepting disease. individual difference of physical quality, and ambivalence. But they return to the experience of being concerned all over again in case of recurrence or metastasis of the disease even though they come out of such stage, and they always have ambivalence even in the condition with no recurrence and metastasis. In conclusion, the trial of alternative therapy for cancer patients could be explained as the adaptive behavior to the disease which is difficult to be cured. the cancer. The cancer patients are exposed to the side effects and harm without the examined information resources. Therefore the nurse should well aware of the alternative therapy and be able to do the appropriative management through the open communication with the patients who are under the trial of alternative therapy.

  • In this study, we investigated the quality characteristics of yogurt with different amounts(0.5, 1.0, 1.5, 2.0%) of Sansuyu(Corni Fructus) extracts. The yogurt products were evaluated for sensory properties, acid production(pH, titratable acidity) and the number of viable cells during storage up to 21 days at $10^{\circ}C$. The products containing 0.5% and 1.0% Sansuyu extracts showed the highest scores for color, smell, softness, taste, and overall acceptability. For the intensity characteristic scores, color, smell and bitter taste increased as the proportion of Sansuyu extract increased. Softness was lowest, but it was highest in the 0.5% and 1.0% Sansuyu extracts. During storage, titratable acidity increased while pH gradually decreased. pH was lower in the sample with Sansuyu extract than that of the control, and the titratable acidity increased with increasing Sansuyu extract content on day 0. There was significant difference in viable cell counts among the samples. These results indicated that the yogurt added with 0.5~1.0% Sansuyu extract was acceptable.
