It is, therefore, essential to have an appropriate animal model for detailed analysis of the role of H. pylori played in gastric carcinogenesis. There is a wealth of evidence to support that over production of inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2) is involved in the pathogensis of various cancer in both rodents and humans. The aim of this study was to establish a mouse model for H. pylori-associated gastric carcinogenesis and to identify the role of inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2) played during the gastric carcinogenesis in mice. Eighty-three specific pathogen free, six-week-old male C57BL/6 mice were randomly divided into seven groups. Animals of the group 1, 2, 3, 4 were given MNU in their drinking water at the concentration of 200 p.p.m. for total five cycles of one-week regimen with one-week pause. After completion of MNU administration, they were given autoclaved distilled water for one weeks, and groups 1, 2, 3, 5, 6, 7 were inoculated with H. pylori. After completion of H. pylori. inoculation, groups 2 and 6 were given aminoguanidine in their drinking water at concentration of 1000p.p.m. and animals of group 3 and 7 were given the diet containing 200 ppm nimesulide at 12 weeks of age. All animals were killed at 50 weeks of age. The incidences of the glandular stomach tumors in the group 1, 2, 3 and 4 were 87.5%(14/16), 76.4%(13/17), 44.4(8/18), 10.0%(1/10), respectively and the tumor incidence of group 3(MNU→Hp+nimesulide) was significantly lower than those of group 1(MNU→Hp) at the value of P<0.01. The average numbers of tumors of group 2(MNU→Hp+AG : 1.41±0.24) and group 3(MNU→Hp+nimesulide : 0.44±0.12) were significantly lower than those of group 1(MNU→Hp : 2.62±0.36) at the value of P<0.05. Therefore, overproduced iNOS and COX-2 plays an important role in mice gastric carcinogenesis. We concluded iNOS and COX-2 inhibitor have good effects on gastric carcinogenesis.

        진창남,이창훈,오상필,정용욱,송춘복,이제희,허문수 한국어병학회 2003 한국어병학회지 Vol.16 No.2

        The research was carried out to know the occurrence trend of scuticociliatosis and mortality of fingerlings in flounder. The diseased fish were collected from on-land rearing farms and hatcheries of flounder in Jeju Island form January 1991 to December 2001. Occurrence of scuticociliatosis was about 10% of total occurred diseases for 1991 to 1996, but increased to 34.5% in 2001. Although monthly occurrence of seuticociliatosis was not related to season from 1999 to 2001, the highest occurrence was revealed in July and August. Mixed infections of bacteria including Vibrio sp., Edwardsiella tarda, Streptococcus sp., and Flexibacter sp., with seuticociliates were observed. Among the bacteria, Vibrio sp., was the highest frequency(40.1%), and the lowest one(10.1%) was Streptococcus sp., Mortality of fingerlings by seuticociliates was different sharply according to size of fish. Mortality of infected fingerlings below 7㎝ of total length was 53.8%, while that of normal fingerling above 7㎝ of total length was 13.2%. When fish were grown above 25㎝, mass mortality by seuticociliates infection was decreased markedly.

        박규남,박승현,황두영,김형국,이환,최경호,이원재,정욱성,김학주,김세경 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

        Objective : To investgate patterns of serial serum interleukin-6(IL-6) concentrations after initial successful cardiopulmonary resuscitation, and to access differences in serum IL-6 concentrations in patients with Cerebral Performance Category(CPC, 1-2) and CPC(3-5) at the 5th day after cardiacpulmonary resuscitation(CPR). Methods : We studied prospectively 12 patients with spontaneous circulation after cardiopulmonary resuscitation. Venous blood samples were taken 2, 4, 12, 24, 48 and 72 hours after restoration of spontaneous circulation to measure serum IL-6 levels by the enzyme-linked immunosorbent assay. Results : Serum IL-6 concentrations in the severe neurolgically disabled group(CPC, 3-5) were significantly increased at 2, 24 and 48 hours after restoration of spontaneous circulation compared with the less neurolgically disabled group. Also, serum IL-6 concentrations in the severe neurolgic disabled group showed dual peak at 4 and 24 hours. Conclusion : Our study demonstrates significant increase of serum IL-6 in patients with CPC(3-5) after successful cardiopulmonary resuscitation and the significant correlation between early increase of serum IL-6 and poor neurologic outcome. It suggests that early increase of serum IL-6 can be used as a prognostic marker after successful cardiopulmonary resuscitation.

        Esthetic has become an indispensable factors to consider when choosing a orthodontic fixed appliances. However, most of the brackets used on orthodontics are made of metallic materials because those esthetic alternatives showed several controversies like brittleness, deformation and discoloration. The AISI austenitic classes, 303, 304, 316 and 317 type of stainless steels are frequently used for orthodontic metallic brackets fabrication. The composition of this type of alloy is 18 wt% of chrome, 8 wt% of nickel, 2 to 3 wt% of molybdenum and low carbon contents. They seemed to show relatively good characteristics to fabricate the orthodontic brackets in previous study. But in hostile condition such as low pH containing chlorine ion like saliva they might to be attacked by localized corrosion. The purposes of this study were to evaluate the microstructure, microhardness, corrosion resistance, frictional resistance and cytotoxocity of 316L(MD), AISI 304(AC) and experimentally produced super stainless stell bracket(SS). The results from this study were as follows; 1. MD and AC showed (Cr, Fe)23C6 precipitating in austenite matrix. SS showed small ferrite island forming in matrix. 2. SS showed the highest polarization resistance(Rp). SS seemed to have the highest corrosion resistance since SS showed 0.9 ×10-3 MPY, MD showed 3.7 ×10-3 MPY and AC showed 7.4×10-3 MPY. 3. The friction resistance decreased from 3 days to 4 weeks for SS(p<0.05). MD showed significant differences for the measurement of 3 days, 2 weeks and 4 weeks. AD did not showed significant differences to 3 days but increased at 2 weeks(p<0.05). 4. SS seemed to have the best biocompatibility since SS showed response index of 0/1 (mild), AC showed 1/2 (mild+) at cytotoxicity test. According to these results, SS seemed to have sufficient characteristics to fabricate the orthodontic brackets and superior corrosion resistance compare to AISI 300 type stainless steel which could lower the chance of nickel allergic reaction.

        諸商律,李寅杰,김랑춘,李準琸,張南日,洪鍾旭 慶北大學校 1974 論文集 Vol.18 No.-

        This study was made to get the cultural information for increasing yield with recently improved variety, investigating the effects of different transplanting date and seed size, the number of plant per hill on the growth, and the yield and yield components in rice. The results obtained were summaried as follows: 1. In larger seed, the percentage of germination was higher and the early growth was more vigorous. However, there appeared no effects of seed size in the later growing period. 2. When the young plants sown on April 26 were transplanted on 5th, 15th, 25th of June and 5th of July with 10-days interval, the heading date was promoted in earlier transplanted plots. The days to heading, however, was shortend. 3. In the case of the earlier transplanting in Tongil variety, the maximum number of tillers was increased, the percentage of effective tillers was decreased, and the rate of ripened grains was slightly higher. The yield was the highest in the transplanted plot of June 25. The next came the transplanted plots of 25th, 5th of June and 5th of July. In the early transplanted plot of Palkweong variety, heading was also promoted. The days required for heading were also proportionly shortend, the number of the effective tillers was smaller and the percentage of ripened grains also decreased. The productivity was the highest in transplanted plot of June 25. 4. When the number of plants per hill was increased, the heading date was promoted, the number of panicles was high and the number of grains per panicles was decreased. In the early transplanting of Tongil variety, the yields was the highest in 4-plants plot. When transplanted late, it was the highest in 6-plant plot. In Palkweong variety, there was general tendency of increasing of yield as the number of plants per hill increased. 5. The dwarf disease of Tongil variety and the stripe disease of Palkweong variety occurred much in case of the lesser number of plants per hill and the earlier transplanting.

      • Al₂O₃-TiO₂ 복합체의 기계적 및 열적 특성에 미치는 MgO의 첨가효과

        박재성,이상욱,남효덕 영남대학교 재료기술연구소 2000 재료기술연구 Vol.1 No.1

        Aluminum titanate(Al₂O₃TiO₂ ) was known to low thermal expansions over wide temperature ranges, but showed poor mechanical properties. The present studies have been concerned with the thermal and mechanical properties of aluminum titanate based on the ceramics containing MgO. The addition of MgO powder to Al₂O₃-TiO₂ inhibited the grain growth and this result can be increased sintering density and vickers hardnes s. The thermal expansion of Al₂TiO_(5) increased with the addition of MgO and also increased with temperature up to 1000℃, however, it decreased in the temperature range between 1000℃ and 1200℃ during heating. The test of thermal shock showed that the addition of 10 wt% MgO generated macrocrack of 25%.
