표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

중증 재생불량성빈혈에서 타인 혹은 HLA 불일치 혈연간 골수이식을 위한 cyclophosphamide와 antithymocyte globulin전처치 요법

이정희,이제환,김신,설미이,이정신,김우건,김상희,지현숙,박찬정,이규형 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.1

배경: Cyclophosphamide와 ATG의 전처치 요법은 HLA가 일치하는 형제간 골수이식에서는 매우 효과적인 것으로 알려져 있으나, 타인 혹은 HLA 불일치 혈연간 골수이식에서는 전처치 요법으로서 불충분한 것으로 보고되었는데, 주요 문제는 착상 부전이었다. 우리나라를 포함하는 극동아시아 지역의 국가들에서 발표되는 보고에 의하면 타인이식을 포함하여 골수이식 후 착상 부전과 이식편대숙주질환의 발생이 서구 국가들로부터의 보고에서보다 적은 것으로 알려져 있다. 저자 등은 6예의 중증 재생불량성빈혈 환자들에서 질병 초기에 Cyclophosphamide와 ATG만을 이용하여 전처치를 한 후에 타인 혹은 HLA 불일치 혈연간 골수이식을 시행하였다. 방법: 1999년 5월부터 2000년 4월까지 서울중앙병원에서 타인 혹은 HLA 불일치 혈연간 골수이식을 시행 받은 성인 중증 재생불량성빈혈 환자들을 대상으로 하였다. 골수이식을 위한 전처치 요법으로 cyclophosphamide (50 mg/kg/d x 4)와 ATG (30 mg/kg/d x 3)를 투여하였는데, 골수이식 전에 ATG에 대하여 과민 반응을 보였던 한 예 (UPN 120)에서는 ATG 대신에 fludarabine (30 mg/m2/d x 3)을 투여하였다. 이식편대숙주질환의 예방을 위하여 cyclosporine과 methotrexate를 투여하였다. 결과: 연구 기간 중에 모두 6예가 타인 혹은 HLA 불일치 혈연간 골수이식을 시행 받았는데, 5예는 타인으로부터 골수를 공여 받았으며, 1예는 HLA의 표현형이 하나의 유전자좌에서 일치하지 않는 형제로부터 골수를 공여 받았다. 타인 골수이식을 받은 5예 중에서 3예의 공여자는 HLA의 표현형이 일치하였으며, 1예는 하나의 유전자좌가 major mismatch였고, 1예는 하나의 유전자좌가 minor mismatch였다. 추적기간의 중앙값은 406일 (범위, 328-643일)인데, 6예 모두에서 착상된 상태를 유지하면서 생존해있다. 2예에서 3도의 급성 이식편대숙주질환과 전신성 만성 이식편대숙주질환이 발생하였다. 결론: Cyclophosphamide와 ATG의 전처치 요법은 재생불량성빈혈의 초기에 타인 혹은 HLA 불일치 혈연간 골수이식을 시행 받은 한국인 환자들에서 충분히 착상을 가져올 수 있는 요법으로 생각된다. 비록 본 연구의 대상 환자 수가 적지만 결과는 매우 고무적이다. HLA가 일치하는 형제가 없는 중증 재생불량성빈혈 환자의 경우에 타인 골수 공여자에 대한 검색을 조기에 시행해야 하며, 타인 혹은 HLA 불일치 혈연간 골수이식을 질병 초기에 적극적으로 고려해야 할 것으로 생각된다. Background: Cyclophosphamide (CY) and ATG regimen was reported to be insufficient for alternative donor BMT in SAA patients due to high incidence of graft rejection. The rates of graft rejection and GVHD after allogeneic BMT including unrelated donor transplants seemed to be lower in reports from Asian countries of Far East. We applied CY/ATG regimen to six patients with early stage of SAA transplanted with marrow from alternative donors other than HLA-identical siblings. Methods: Three patients were transplanted from HLA-phenotypically identical unrelated donors, two from one-locus mismatched unrelated donors, and one from an one-locus mismatched sibling donor. Four patients received no previous therapy for SAA, and two received one course of immunosuppressive therapy with ATG. Preparative regimen was CY (200 mg/kg) plus ATG (90 mg/kg) in all patients except one who had had an anaphylactic reaction to ATG prior to BMT and received fludarabine (90 mg/m2) in place of ATG. Cyclosporine plus methotrexate were given for GVHD prophylaxis. Results: All six patients engrafted and all are alive with durable engraftment at a median follow-up of 406 days (range, 328 to 643). Two patients developed grade III acute GVHD and extensive chronic GVHD. Conclusions: CY/ATG regimen may be sufficient in Korean patients with early stage of SAA transplanted with marrow from alternative donors. Although the number of patients in present study is small, results are encouraging. Stem cell transplantation using alternative donors may be considered at early stage of aplastic anemia.

In this paper, we propose a scheduling analysis method of WIP(Work In Process) in Flexible Manufacturing System using Time Petri Nets unfolding. Unfolding of Petri nets is a partial order-based method for the verification of concurrent system without the state space explosion. The aim of this work to is to formulate the scheduling problem of the general cyclic state, to minimize the make span and to satisfy economical constraints. The method is based on unfolding of the original net into the equivalent acyclic description.

인체 대장암에서 72kDa 제 4형콜라겐 분해효소의 발현

김정은,손건영,전수한 경북대학교 병원 1998 경북대학교병원의학연구소논문집 Vol.2 No.1

수술 절제한 대장암 45예에서 Northern blot analysis와 gelatin zymography를 시행하여 72kDa 제 4 형콜라겐 분해효소의 mRNA치와 활성도를 조사하였다. 대장암에서 주위 정상조직에 비해 이 효소의 mRNA치가 증가하였으며 단백질 합성단계에서 효소의 활성도와도 연관되었다. 특히 활성형인 62kDa의 활성도가 크게 증가하였다. 암진행에 따른 이 효소의 활성도 변화는 T2와 T3에서 암조직과 정상조직사이에서 mRNA치와 효소활성도에 차이가 있었으나 전반적으로 암의 침윤도, 림프절 전이, 듀크스 병기에 따른 유의한 차이는 볼 수 없었다. 암침윤과 전이에는 제 4 형콜라겐 분해효소 외에 딴 metalloproteinase들, plasminogen activator등 여러 가지 다른 단백질 분해효소도 관여하며, 암종류에 따라 이들 효소의 작용정도가 차이가 날 수 있다. 또 조직 억제제인 tissue inhiitors of metalloproteinase(TIMPs)와의 균형관계도 고려해야 한다. 그러므로 대장암에서 72kDa 제 4 형콜라겐 분해효소의 증가된 활성양상을 이들 다른 인자들과 함께 관찰하면 암의 진행정도를 나타낼 수 있는 보다 뚜렷한 지표를 만들 수 있을 것으로 생각된다. Type Ⅳ collkagenases are thought to play a role in the proteolysis of the basement membrance and the extracellular matrix by the malignant cells that occur early in the development of invasive tumors. In several human tumors, including breast, colonic, ovarian, and gepatocellular carcinomas, Type Ⅳ collagenase expression has been positively correlated with tumor invasiveness. In this study, we examined the expression and the activation of 72kDa Type Ⅳ collagenase in cancerous and normal tissues of the colon and, we attempted to clarify its clinical significance in 45 cases of human colorectal cancer by using northern blot analysis and gelatin zymography. This study showed that the level of 72kDa Type Ⅳ collagenase mRNA was increased in colorectal cancer and that this increase was associated with increased enzymatic activity. While there was a difference in the expression and the activation of this enzyme between T2 and T3, this enzyme activity did not show a definite correlation with cancer progress as measured by the depth of tumor invasion and lymph node metastasis.

Objective : Since Korea has been known to be of the endemic area for hepatitis B virus(HBV) infection, vaccination for HBV has been recommended for all neonates in Korea. After starting vaccination in 1983, the change of sero-positivity of HBsAg and HBsAb is expected. This study was carried out to investigate the seropositive rate of hepatitis B virus surface antigen and antibody in high school freshmen students in Chungju-city. Methods and Materials : From 1998 to 2001, a total of 11,735 who were born in 1982 to 1986, were enrolled in this study. HBsAg and anti-HBs were tested by reversed passive hemagglutination and passive hemagglutination, respectively. Results : The study population was 11,735 students who were composed of 5,813 males (49.6%) and 5,914 females (50.4%). The HBsAg sero-positivity of male and female students was 3.25% (n=381) and 2.59% (n=153) respectively. The anti-HBs sero-positivity of male and female students was 62.2% (n=3,154) and 64.1% (n=2,969) respectively. There are significant difference observed in comparison of HBsAg and anti-HBs seropositivity according to sex (p<0.05). From 1982 to 1986 on birth year, anti-HBs sero-positivity has been increased significantly from 63.3% to 73.3%. But the change of HBsAg sero-positivity has not been changed significantly. Conclusions : As compared with previous studies of HBsAg and anti-HBs, the sero-positive rate of HBsAg has not been changed but that of HBsAb has been increased significantly. This result revealed that the effect of HBV vaccination program was successful.

It has been 22 years since the first apartment was built in Korea. Recently more and more apartments have been being introduced to Korean people and has been changing traditional Korean life style. Residents of apartment complexes in Korea suffer from various problems such as sisregarding of traditional Korean exterior space, pathology, improper community facilities and green spaces, destruction of natural environment, and lack of diversity and chracter in buildings and outdoor spaces. Historically the techniques of residential site design have been developed through three evolutionary steps. The first step was the Garden City idea of Ebenezer Howard in England(1898). In his conceptual plan he located Grand Avenue in the center of residential site. However, the green space was divided by road from residential site. The second step was the Sunnyside Gardens in New York(1924). The city Housing corporation of New York City built apartments with new concept which contained large common green spaces within a block surrounded by apartment buildings. This was possible because the lot subdivision no longer existed. The third step was the Radburn Plan(1929) in New Jersey. This was the second project of the City Housing Corporation. This plan invented two important concepts in residential site design. The one is super block concept which does not permit vehicle road within a large block. The other one is culs-de-sac road of which has a dead end on the one end. These two concepts contribute to making internal common green space without car traffic. With this concept the housing was ideally interwoven with green spaces. The Radburn Plan was the beginning of cluster development in residential site and innovation for moter age. At present, after 50 years from Radburn Plan, the basis concept of it is still valid and useful in residential site design. However, we need to make another evolutionary step for the better quality of living. The situations in Korea are different from those in western countries. Apartment is one of the western-origin housing types. Koreans have to modify western-oriented apartment buildings and site plans for cultural adaptation. Furthermore, we have to create new concepts for the better quality of living. Followings are the propositions for site design of apartment complex in Korea. 1. Cultural Aspect-One of the traditional characters of Korean exterior space os intermediate space between interior and exterior space. In order to provide intermediate space, sequence planning and gradual change of space atmosphere in outdoor space design is needed. 2. Social Aspect-We have to consider life cycle of residents, provide various community activities, increase natural elements, and decrease pathologh in apartment complex. 3. Functional Aspect-Pedestrian was should be separated from vehicle way in any case. Pedestrian way system can be benefited from combining with green space system. Green spaces should have systematic link instead of dispersed disposition without connection. The land use pattern should also have systematic and functional relationship. 4. Ecological Aspect-Dynamic equlibrium in eco-system should be preserved or modified with minimum change during and after development. The elements in inventory should be checked are land slide, erosion, surface and ground water, vegetation, wildlife, micro climate, etc. 5. Perceptional Aspect-Apartment complex should be considered as a group form as well as individual form of buildings. It is recommendable to divide outdoor spaces into human scale and to give diversity to each space and building instead of uniform treatment.
