Backgrounds : The expression of the MDR-1(multidrug resistance)encoded P-170 glycoprotein(p-170)and CD34 have been well known to be associated with drug resistance in AML(acute myelogenous leukemia). P-170 and CD34 expression in AML have been reported as unfavorble prognostic parameters separately. Methods : P-170 glycoprotein expression was analyzed in correlation with CD34 expression and clinical response in 15 consecutive patients with de novo acute myelgenous leukemia (AML). They were measured with flow cytometry after direct and indirect immunofluorescence staining simultaneously. Results : 1) The positive rate of P-glycoprotein and CD34 were in two of 15 patients(13%), seven of 15 patients(46%), respectively. 2) One of two P-170 positive patients as compared with 7 of 13 P-170 negative patients achieved a complete remission(CR), which showed no clinical significant difference. 3) There was no significant correlation between P-glycoprotein and CD34 expression(r=0.29, p=0.28). 4) In de novo acute myelogenous leukemia, there was no case which expressed both P-170 and CD34 simultaneously. 5) P-glycoprotein and CD34 were not expressed in acute promyelocytic leukemia group. 6) Cytogenetic abnormalities did not show any significant difference in the rate of P-glycoprotein expression, CD34 expression and complete remission. Conclusion : CD34 and P-glycoprotein in acute myelogenous leukemia were independent parameter in this study. Further investigations are warranted for clinical implication.

배경: 이식편대숙주 질환은 동종골수 이식후 발생할 수 있는 가장 중요한 합병증의 하나이다. 일반적으로 이식편대숙주 질환이 서구에 비하여 한국을 비롯한 아시아 국가에서 드물다고 알려져 있다. 방법: 저자들은 1993년 12월부터 1997년 6월까지 동종골수이식을 받은 전체 44명의 환자를 대상으로 급성 및 만성 이식편대숙주 질환의 빈도와 임상 양상을 조사하여 분석하였다. 대상환자중 남자가 27명 (61%) 이었고, 여자가 17명 (39%)이었다. 중앙연령은 33.5세 (범위, 16-47세)였다. 17명은 급성골수성 백혈병, 6명은 급성림프구성백혈병, 11명은 만성골수성백혈병, 8명은 중증재생불량성빈혈, 1명은 골수이형성증후군, 그리고 나머지 1명은 신경아세포종(neuroblastoma) 환자였다. 이식편대숙주 질환 예방으로 methodtrexate와 cyclosporine복합요법을 시행하였다. 결과: 3명에서 급성 이식편대숙주 질환이 이식후 18일에서 48일 사이에 관찰되었다(빈도, 7%). 급성 이식편대숙주 질환정도는 3도, 2도 그리고 1도가 각 한명씩이었다. 4도 급성 이식편대숙주 질환은 관찰되지 않았다. 13명의 환자가 만성 이식편대숙주 질환을 경험하였다(30%). 이들 중 10예는 제한성 병변이었고 3예는 전신성 병변이었다. 만성 이식편대숙주 질환의 주된 발병 증상 또는 징후는 황달/간기능 이상(8예)과 구강점막병변(4예)이었다. 한 명의 환자가 이식 후 107일에 간 이식편대숙주 질환에 의한 간부전으로 사망하였다. 결론: 한국인 환자에서는 동종골수이식 후 급성 및 만성 이식편대숙주 질환의 빈도가 구미의 환자에 비하여 상대적으로 낮고 그 정도도 덜한 것으로 보인다. 한국인 환자에 가장 적합한 이식편대숙주 질환 예방 방법의 정립을 위한 계속적인 연구가 필요하다고 사료된다. Background: Graft-versus-host (GVHD) disease is one of the most important complications after allogeneic bone marrow transplantation (BMT). Generally, it has been known that graft-versus-host disease is less frequent after allogeneic BMT in Asian countries including Korea when compared to western countries. Methods: We investigated the frequency and clinical pattern of acute and chronic GVHD in 44 consecutive patients who underwent allogeneic BMT between December 1993 and June 1997. There were 27 male (61%) and 17 female (39%) patients with median age of 33.5 years (range, 16-47). Seventeen patients had acute myelocytic leukemia (AML), 6 acute lymphocytic leukemia (ALL), 11 chronic myelocytic leukemia (CML), 8 severe aplastic anemia (SAA), 1 myelodysplastic syndrome, and 1 neuroblastoma. Methotrexate/cyclosporine combination was given for acute GVHD prophylaxis. Results: There patients (7%) developed acute GVHD median 31 days (range, 18-48) after BMT. There were one grade 3 acute GVHD involving the liver. There was no patient with grade 4 acute GVHD. Thirteen patients (30%) developed chronic GVHD median 100 day (range, 53-266) after BMT. Ten cases were limited stage and 3 were extensive stage. Frequent initial manifestations of chronic GVHD were jaundice/liver function abnormality in 8 cases and oral mucosal lesion in 4 cases. One patient died due to liver failure which were felt to be seconday to chronic GVHD 107 days after BMT. Conclusion: Acute and chronic GVHD are less frequent in Korean patients after allogeneic BMT when compared to historical data from patients from western Europe or United States. In cases of chronic GVHD, mild forms of disease predominate. Optimal strategy for GVHD prophylaxis in Korean patients remains to be defined.

동종 골수 이식한 백혈병에서 단반복 유전자로 살펴본 혼합 키메라 현상의 의의

장대영,이정신,서철원,이규형,이제환,지현숙,박찬정,한면수,최동원,김정균,최성준,김성배,김상위,김우건,김상희 대한조혈모세포이식학회 1998 대한조혈모세포이식학회지 Vol.3 No.1

연구배경 : 동종 골수 이식한 백혈병에서 키메라 현상의 분석은 착상, 질병 재발과 이식 거부를 이해하는데 도움을 줄 수 있다. 최근 STR을 PCR로 증폭한 검사법에 의해 매우 민감하고 유용하게 혼합 키메라 현상을 검출할 수 있다고 보고되고 있으나, 이 방법의 민감도와 임상적 의의는 아직 완전히 정립되지는 않았다. 따라서 PCR-STR검사법이 혼합 키메라 현상을 민감하게 검출하는지 보고, 동종 골수 이식 후 혼합 키메라 현상의 변화 양상을 관찰하고, 키메라 현상의 임상적 의의를 보고자 하였다. 방법 : 형제로부터 동종 골수 이식한 급성 백혈병 6명과 만성 백혈병 2명의 모두 8명을 대상으로 하였다. 44개 골수 검체에서 phenol/chloroform방법에 의하여 단핵세포 DNA를 추출하였다. DNA는 CTT 삼중체, vWA와 amelogenin시발체를 이용하여 증폭하였다. 증폭 산물은 5% 폴리아크랄아미드 젤에서 전기영동 뒤 은 염색으로 확인하였다. 2명의 DNA를 여러 비율로 혼합하여 상기 검사를 하여 검출 가능 최소 농도를 결정하였다. 결과 : 상기 검사법의 검출 가능 최소농도는 0.25%였다. 혼합 키메라 현상은 8명중 4명에서 관찰되었다. 혼합 키메라 현상은 보인 1명에서 급성 및 만성 이식편대 숙주 질환이 나타났고, 완전 공여자 키메라 현상을 보인 1명에서 만성 이식편 대 숙주 질환이 나타났다. 점진적으로 증가하는 혼합 키메라 현상을 보인 2명은 이식 후 12개월에 질병 재발을 보였으나, 완전 공여자 키메라 현상을 보인 경우엔 재발이 관찰되지 않았다. 결론 : PCR-STR검사법은 동종 골수 이식 후 남아 있는 환자 세포를 검출하고 키메라 현상을 관찰하는데 유용한 방법이다. 또한 이 검사법은 동종 골수 이식 후 재발의 조기 진단, 이식편 대 숙주 질환의 평가와 면역 관용에 임상적으로 응용할 수 있으리라 생각한다. Background : Chimerism analysis after allogeneic bone marrow transplantation (BMT) for leukemia could be helpful understanding of the early marrow engraftment, disease relapse, and graft rejection. Recently, a PCR technique which amplifies short tandem repeats(STR) has been reported to be highly sensitive and reliable in detecting mixed chimerism. But its sensitivity and clinical significance has not been established. The purpose of this study was firstly, to confirm whether a PCR-STR in highly sensitive enough ti assess mixed chimerism, secondly to monitor the changing patterns of mixed chimerism after allogeneic BMT, and lastly to determine correlation between the chimeric status and the clinical outcome. Methods : A study was made eight patients (six with acute leukemia and two with chronic leukemia) who underwent unmanipulated allogeneic BMT along with matched donors. DNA was extracted from mononuclear cells of 44 bone marrow samples using a phenol/chloroform method. Amplification of DNA was done using CSFIPO-TPOX-TH01(CTT) triplex with or without vWA or amelogenin primer. The amplified product was separated on 5% polyacrylamide gel and was confirmed by silver staining. The sensitivity of CTT triplex method was determined by mixing DNA from two person in serial proportion using the same method. Results : The sensitivity for CTT triplex method was 0.25% Mixed chimerism was documented in 4 of 8 patients. ONe of four patients with mixed chimerism developed acute and chronic graft versus host disease (GVHD) and one of four patients with complete donor chimerism also developed chronic GVHD. Two patient with progressive mixed chimerism relapsed at 12 months post-BMT, whereas no patient with complete donor chimerism has relapsed. Conclusion : The study has found that PCR-STR was an effective method for the detecting residual host cell and monitoring the chimeric status after allogenic BMT. PCR-STR can also be clinically applicable in early prediction of relapse, appropriate assessment of GVHD, as well as tolerance after allogeneic BMT.

뜻의 성숙으로서 의지와 뜻 : 의지

Fixation of meaning brings about will's rise. Negation of meaning by will is associated with nihilism We can pass though nihilism and overcome it by thorough examination of will's nature. Will is known through human body, but its autonomy makes it independent from the body. And the autonomy gives the power to overwhelm nihilism. Will to power is originated from the radical nihilism. The ultimate form of will to power is changed into will to will and the way to sense.

幾何學의 性格에 관한 認識論的 및 論理的 考察

金渭星 釜山水産大學校 1974 論文集 Vol.13 No.-

This paper is concerned with the problem of the nature of geometry as knowledge. It analyzes the nature from epistemological and logical viewpoints. According to the dichotomy of knowledge into the empirical and the a priori, firstly the systematization of geometry on the foundation of the former is pursued in vain for inseparable non-empirical elements within the axioms and definitions. And then the way of the latter is followed in Kantian Philosophy of Mathematics, which sees geometrical knowledge as synthetic judgment a priori. He presupposes the a priori and synthetic character of geometry as the fact found in our knowledge and seeks its source in the pure intuition. Another dichotomy of analytic-synthetic distinction in Kant contributes to the a priori geometry, but becomes outdated because it disregards that subject-predicate relation is not universal in the judgments. It comes out that explicit definitions are ambiguous and confounded in facing the adequate definitions. They are revealed as implicit definitions which Formalism uses in making geometry strict and consistent. Formalism makes it possible to comprehend non-Euclidean geometries in compatible way with the Euclidean in their formal logical structures. Pure geometry is uninterpreted and founded only on Formalism. But the choice of geometry asks criteria by which a geometry is found most adequate to explain and describe the world of experience. Conventionalism holds that all systems of geometry are only conventions and they are chosen only by the principle of simplicity in application to the facts. But it fails to make strict distinction between mathematical geometry as pure and physical geometry as applied.

뜻의 길 : 의미의 철학적 해명(뜻의 구조)

김위성 釜山大學校 1992 人文論叢 Vol.41 No.1

The concept of Korean 뜻 has both the element of meaning and the one of will. Therefore the illumination of its structure is aided by the comparison between the philosophical systems of meaning and will, e.g. Schlick's philosophy of meaning and Nietzsche's philosophy of will. Meaning and will must be comprehended through 뜻, and can have their proper place and be united into one. 뜻. -is and 뜻, does are the results of the process, and they are the moments which show various forms of 뜻.

In this study, seventeen kinds of composite resins, lately used in Korea, were devied into three groups and used. Seven of them were light curing composite resins for anterior teeth, four of them were light curing composite resins for posterior teeth and the rest six were chemical curing composite resins for anterior and posterior teeth. In respective samples, heat of reaction, th highest point of temperature and the time to reach the highest point of heat liberation were measured by using DSC under 37℃ isothermal condition. Including the filler content, the correlation of the data were analyzed and the characteristics of three groups were compared one another. From the experiment the following results were obtained ; 1 In light cured resins, as the content of filler increased, heat of reaction and the highest point of temperature were decreased. 2. In chemical cured resins. as the highest point of temperature and the heat of reaction increased, the time to reach the peak heat liberation was decreased. 3. The heat of reaction from light cured composite resins for anterior teeth is higher than that of light cured composite resins for posterior teeth. 4. The light cured composite resins set faster than the chemical cured composite resins but the highest point of temperature and the heat of reaction of the light cured composite resins for anterior teeth were greater than the other two groups.

空間의 唯一性에 관한 考察

金渭星 釜山水産大學校 1973 論文集 Vol.11 No.-

The present paper concerns itself primarily with the problem whether there must be only one space. The absolute space of Newton and the space of pure intuition of Kant as the examples were examined on their uniqueness. Newtonian space was not the necessary condition in explaning the phenomena of motions. It could be replaced by another space, for example Mach's, which also made it possible to systematize the mechanics, even though it denied inertia as the property of things. Inertia depended rather upon the other matters than on the essential quality of a thing. Kantian space was investigated in connection with its infinity and the certainty of Euclidean geometry. Its uniqueness did not follow from the infinity. Euclidean geometry as the probable ground of the uniqueness did not follow from the pure intuitive space and not hold a priori. And we could suppose a space of dream with non-contradiction and publicity. It opened the possibility of multi-spaces. Therefore there is nowhere the necessity of the uniqueness of space.
