Treatment with MMF for them, case 1 present steroid-induced hepatopathy, case 2 present anemia, so treated with Human IgG and blood transfusion. 3(case 1) or 2(case 2) months after initial treatment, clinical features were improved, and continuous monitoring is needed.

PCR과 SDS-PAGE를 이용한 Bifidobacteria의 동정

박시홍,송희성,이지연,김해영 경희대학교식량자원개발연구소 2005 硏究論文集 Vol.24 No.-

SDS-PAGE를 이용한 단백질 패턴의 분석결과, 같은 종의 Bifidobacterium은 동일한 단백질 패턴을 보이며, 다른 종의 Bifidobacterium은 서로 다른 패턴을 보이고 있는 것을 확인하였다. 따라서 SDS-PAGE를 이용한 whole cell protein 패턴 분석으로 Bifidobacterium을 간편하고 빠르게 동정할 수 있는 가능성을 보였다. DNA homology 98% 이상으로 PCR에 의해 동정에 어려움이 많았던 B. catenulatum, B. Pseudocatenulatum group, B. animalis을 SDS-PAGE로 확인한 결과, B. catenulatum과 B. pseudocatenulatum, B. animalis는 뚜렷한 단백질 패턴의 차이를 보임으로써 구별이 가능했다. PCR 수행 시 primer제작은 기존에 보고된 것과 NCBI blast program을 통하여 제작을 하였으며, 그 결과 B. longum, B. bifidum, B. adolescentis 3종류의 종에서만 특이적으로 band가 나타나는 것을 확인할 수가 있었다. 본 실험에서는 SDS-PAGE와 PCR을 이용한 균주 동정법으로 신속하고 정확하게 Bifidobacterium을 탐색할 수 있었으며, 발효유 제조나 의약품 제조 등 산업적으로 이용 될 수 있을 것이다 (Mitsuoka, 1984). Bifidobacterium is a Gram-positive obligate anaerobic bacterium which is able to change cellular shape by nutritional conditions and dominant species in intestinal microflora of human. In order to identify Bifidobacteria spp. in human intestine, PCR and SDS-PAGE of whole cell proteins were used. Species-specific primer sets based on the 16S rRNA, 16S-23S intergenic spacer and heat shock protein genes of three Bifidobacteria spp. were constructed using NCBI blast program (Bifidobacteria adolescentis, B. longum and B. bifidum). PCR products using each primer sets showed the same sizes of expected target genes. From the SDS-PAGE of whole cell proteins in bifidobacteria, profiles of SDS-PAGE between 13 type strains showed distinct differences. These methods will be useful for monitoring and evaluating Bifidobacteria spp. in human intestine microbial population.

본 연구에서는 일반적으로 섭취하고 있는 식품재료나 음식 중에 공통적으로 함유한 성분 또는 가공중에 많이 첨가되는 성분을 선정하여 이들이 Helicobacter pylori 생육에 어떤 영향을 미치는지를 검토하였다. 첫째, 일반식품의 주요 성분인 탄소원, 질소원, 무기질을 대상으로 Helicobacter pylori 생육에 미치는 영향을 검토하였다. 그 결과 식품성분 중 탄소원의 종류에 따라 균일 생육활성은 다르게 나타났다. 우선 단당류가 이당류나 다당류에 비교하여 생육을 촉진하였고 특히 단당류 중 포도당은 가장 균의 생육에 큰 영향을 미치는 것으로 나타났다. 그러나 만노오스는 균의 생육을 오히려 억제시키는 것으로 나타났다. 당알코올류인 솔비톨, 만니톨, 말티톨, 크리시톨 등은 균의 생육에 아무런 영향을 미치지 않은 것으로 나타났다. 질소원과 Helicobacter pylori의 생육과의 관계는 평소 식생활에서 많이 섭취된다고 생각되는 일반 음식에 많이 함유되어 있는 유기형 아미노산 성분고 무기형 질소화합물을 대상으로 균의 생육 정도를 비교하였다. 리신, 메티오닌, 시스테인, 트립토판 등은 균의 생육을 촉진하고 아르기닌, 황산암모늄, 염화암모늄 등은 균의 생육에 도움이 되지 않고 암노니아, 요소등은 균의 생육에 도움이 되지 않고 암모니아, 요소 등은 균의 생육에 조금 영향을 미침을 관찰할 수 있었다. 특히 리신과 메티오닌은 가장 균의 생육에 영향을 미치는 것으로 나타났다. 무기염류의 영향에서는 황산마그네슘, KH-2PO_4, 염화마그네슘 등은 큰 영향을 미치지 못하였고 황산철, 염화제일철, 염화제이철은 생육을 억제하는 것으로 나타났다. 식품첨가물의 Helicobacter pylori의 생육 정도를 검토한 것으로, 그 다음이 질화나트륨, 염화나트륨 순이었으며 토코페롤은 전혀 생육에 영향을 미치지 못하였다. The purpose of this study was to choose principal food components contained in diet foods and food additives used for manufacturing processed foods, and elucidate their in vivo effects on the growth pattern of Helicobacter pylori. To do this, the antibacterial effects of various sources of carbon, nitrogen and mineral as an effect agent on Helicobacter pylori were first assessed based upon bacterial growth degree. Results show that the source of carbon tested had different effects on bacterial growth of Helicobacter pylori. It was revealed that a promotional effect of monosaccharides resulted in enhanced growth of Helicobacter pylori compared with disaccharides and polysaccharides. In particular, glucose was observed to be most effective in growth of Helicobacter pylori among monosaccharides tested, whereas mannose to hinder the growth of Helicobacter pylori. Polyols such as sorbitol, mannitol, maltitol and xylitol was, however, observed to show no promotion or suppression effect on growth of Helicobacter pylori. Apart from these, the sources of amino acid and inorganic nitrogen were chosen and tested to assess the promotion or suppression effect of nitrogen sources on growth of Helicobacter pylori. It was found that amino acid such as lysine showed its promotion effect on the growth of Helicobacter pylori, while arginine, (NH_1)_2SO_4 and NH_4Cl showed no effect on its growth. Ammonia and urea were, however, observed to have a positive effect on the growth of Helicobacter pylori. Among these effect agents, lysine and methionine were revealed to show the most positive effect on growth of Helicobacter pylori. Minerals such as MgSO_4, KH_2PO_4, and MgCl_2 appeared to exert their positive growth effects, whereas CaCl_2, and CaSO_4 had a little effect. In addition FeSO_4, FeCl_2, and FeCl_3 brought suppression on the growth of Helicobacter Pylori. In studies of the growth of Helicobacter pylori by food additives, ascorbic acid showed extreme suppression on its growth. Sodium nitrate and sodium chloride were also found to be of negative effect on the growth of Helicobacter pylori in order of degree, whereas tocopherol had nothing to do with microbial growth.

박형빈,강번중,송해룡,구경회,정순택,조세현 대한골절학회 2002 대한골절학회지 Vol.15 No.4

목 적 : 경골 골절에서 골수정 고정술후 발생하는 교합나사 파단의 빈도와 발생 원인을 밝히고자한다. 대상 및 방법 : 1995년 3월부터 2000년 10월까지 골수정으로 치료하였던 경골 간부골절 82예중 내고정물 파단이 발생하거나 골유합이 이루질 때까지 추시 가능하였던 75예를 대상으로 하였다. 내고정물 파단 빈도와 위치, 골절의 양상, 술후 골절부 신연 및 골유합 이상 여부를 조사하였다. 결 과 : 교합나사 파단은 7예였고 (9.3%), 근위부 두 번째 나사의 파단이 가장 흔하였다. 교합나사으 ㅣ파단은 AO분류 B형과 C형 골절, 술후 골절부가 신연된 경우, 개발성골절, 자연유합 및 불유합의 경우 발생하였다. 결 론 : 교합나사 파단의 주된 요인은 골절부의 골과 골 접촉이 불안정하기 때문이며, 개방성 골절, 지연유합 및 불유합도 교합나사 파단의 위험인자라고 생각한다. 교합나사 파단을 예방하기 위해서는 수술시 골절부 신연을 피해야하며 골절부 골접촉이 불안정한 경우 완전 체중부하를 골유합시까지 제한하여야할 것으로 생각한다. Purpose : The aims of this study were to investigate the prevalence and the causes of crew breakage in tibia nailing. Materials and Methods : Between 1995 and 2000, eighty-two tibial diaphyseal fracture were treated with interlocking nails. The loss of follow-up was 7 cases. We retrospectively reviewed seventy-five cases. We investigated the rate and location of metal failure and evaluated the fracture pattern, the presence of distraction after nailing and union abnormality. Results : Screw breakage was identified in seven cases (9.3%) and most frequently occurred on the second proximal locking screw. Screw breakage occurred in AO type B or C type fractures, fracture site distraction after nailing, open fracture, delayed union and nonunion. Conclusion : The main cause of screw breakage is unstable bone to bone contact on the fracture site caused by comminution of distraction. The open fracture, delayed union, and nonunion also contributing factors for screw breakage. For preventing screw breakage, it is necessary to avoid fracture site distraction and delay full weight bearing in cases having unstable fracture site contact.

송해영,황택성,맹기석,박인환 忠南大學校 産業技術硏究所 1986 산업기술연구논문집 Vol.1 No.2

Several structural factors which governs the thermal stability of poly(vinyl chloride) were investigated by IR and H¹-NMR spectroscopy. PVC-Olefin copolymers having diverse structure were prepared by same reaction conditions such as reaction temperature and comonomer composition. It was found that keto allyl groups in the polymer backbone which were formed through a side reaction show the most pronauncing effect. The content of keto allyl group appeared to increase with the relative amount of olefin comonomers. On the other hand, neither chain branching nor tecticity influenced the thermal stability of copolymer. Also, the content of double bond fromed at chain ends was unrelated to the thermal stability.

朴仁熙,宋海永,金元述 경북대학교 1992 논문집 Vol.24 No.-

Since the opening of this country in 1876, we had kept our own cultural orientation and this cultural orientation had been working as principle of our individual and community life. But this orientation became degraded through the colonial policy of Japan and the set-up of military government by U. S. A and U. S. S. R, and also came to be deformed after the division of the country. From these reasons, it follows that modern Korean Ethics must tend to creativly modify the cultural orientation, which we aimed since 1876, and that Korean Ethics must be based on this fact. This is the question at issue and the object of this paper, For the settlement of the question, this paper develops the following details. First, the concept of Korean Ethics is defined on the level of cultural specificity and universality, and the orientation of Korean Ethics is explaned with relation to that of Korean Culture. Second, we had considered the education of Korean Ethics dividing our modern history into the opeining the country, the colonization, the military government of two powers and the post-establishment of two Korea. Third, the value that Korean Ethics must aim is discussed with reference to man, society and nation. In conclusion, it is argued that with the succession of our cultural orientation, Korean Ethics must be established by way of national consensus, and that through the educative efforts it must be interiorized towards the members of our society.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.

The purpose of this study is to find a way for teaching English reading comprehension to the students of English as a foreign language in Korea and to develop a teaching model for reading comprehension in reading classes. To achieve this purpose, this study was conducted according to the following procedure : (1) Based upon theoretical background and the survey of the English reading strategies, the main experimental study was conducted form March 1999 to December 1999. Two groups of students were selected from the subjects on the basis of test scores. One was the experimental group, 34 students and the other was the comparative group, 32 students. (2) The subjects of the comparative group were presented by traditional methods based on bottom-up process when they studied the main text. But those in the experimental class were instructed through reading strategies. (3) At the end of this work each student had a test. The test was composed of 25 items, 25 minutes, and 25 scores in each. The problems were made up of searching topics, main ideas, organization of passage and inference. The result analyses were shown as follows; (1) The questionnaire reported that almost all the students focused on word power, but neglected reading strategies. So they lost their interest in general English reading activities. (2) The experimental group had higher total comprehension scores, which showed reading strategies were significantly more effective than the comparative. (3) 4 reading strategies (previewing, predicting, scanning, skimming) demonstrated a greater effect in developing the reading comprehension ability of students. Some implications could be drawn from the results of this study; (1) In English reading classes, students could be presented different effective strategies on paragraph levels of the text and practice those strategies to the full use. (2) Students could recognize the importance and utility of reading strategies and do exercises through train to learn and develop their own effective strategies for successful reading.

Purpose : The purpose of this study was to investigate the dietary habits of students in order to identify risk groups according to their Body Mass Index (BMI), and to compare the eating behavior of students in the normal range (19<I≤24) and those in risk groups (BMI≤19, 24<I≤27, BMI>). Method : 1176 elementary school students, 850 middle school students and 672 high school City, were the participants The instrument for this study was a structured questionnaire that included demographic data as well as dietary habits, and the eating behavior instrument developed by Stunkard &essick(1985) and revised by Kim &im (1997). Result : 1) As students moved up in grade level their dietary habits became more irregular and the degree that students chewed food was reduced 2) As students moved up in grade level, a greater number of the students did not eat breakfast. The reasons given were that there were not enough time before classes started(40.4%) and a lack of appetite in the morning(10.6%) in high school students. 3) As for supper, from 67.8 to 81.9% of subjects reported having regular supper. However the rest of the subjects did not eat supper because of anorexia and fear of weight gain. 4) The results identified risk groups according to their BMI showed that for elementary school students, 55.9% were in the low weight group, 5.5% in the overweight group, and 0.9% in the obese group. For middle and high school students, 40.6% and 35.5% respectively were in the low weight group, 7.4% and 6.3% in the overweight group, and 4.1% and 2.5% the obese group. 5) Comparisons of the eating behavior of students in the normal weight group with that of those in the three risk groups showed that there were significant differences in 'hunger' and 'cognitive restraint of eating' in elementary school students, and significant differences in 'cognitive restraint of eating' in middle and high school students. Conclusion : The results of this study show that management of diet in school health sholud be addressed from both the aspect of lack of nutrition and that of excess nutrition. In other words, good diet is as important for students in the low weight group as it is f3r those in the overweight and obese groups. The estatblishment of good dietary habits and eating behavior in students, by nurses and dieticians should be done by providing repeated diet education and involvement in diet counseling.
