돼지 Lecithin : Cholesterol Acyltransferase 의 화학적 성질

최명숙,박용복 ( Myung Sook Choi,Yong Bok Park ) 생화학분자생물학회 1991 BMB Reports Vol.24 No.1

Amino acid residues of lecithin: cholesterol acyltransferase from hog plasma were modified with various chemicals in order to identify the functionally important amino acid residues of the enzyme. At least one sulfhydryl group was found to be essential for the catalytic activity and all four of the sulfhydryl groups may be involved in the self-association process at high enzyme concentrations in vitro. During the self-association process, the sulfhydryl groups may participate in the intermolecular disulfide bond formation. More than one half of tryptophan residues of the enzyme was exposed to the aqueous environment under non-denaturing conditions. Fluorescence quenching studies showed that apolipopotein-AI in the high-density lipoproteins is one of the major contributors in the substrate binding of the enzyme. This interaction seems to be mediated mainly by the hydrophobic interaction between the substrate and the enzyme. The enzyme activity was sensitively modified by thiol, seryl and histidyl modifiers, indicating an importance of those amino acid residues in the function of the enzyme.

출생 때에 토끼는 성숙한 토끼보다 비교적 높은 혈중 콜레스테롤을 포함하고 있으며 그 농도는 수유에 따라 증가하여 수유 2주일에 최대치를 보이다가 수유기간이 끝나는 4주째에는 정상농도로 돌아가게 된다. 사람의 모유 또는 와타나베토끼(유전적으로 혈중 콜레스테롤이 비정상적으로 높은 토끼)의 혈청으로부터 분리한 저밀도 리포단백질을 배지에 포함시켜 출생전 토끼의 대동맥을 조직 배양할 경우 대동액내에 포함되어 있는 콜레스테롤 양의 변화를 관찰하였다. 사람의 모유를 함유한 배지에 먼저 배양한 후 와타나베토끼의 저밀도 리포단백질을 함유한 배지로 옮겨 배양했을 때 출생전 토끼 대동맥내 콜레스테롤 농도는 사람의 모유에서만 같은 기간동안 배양한 대동맥에서와 비슷했다. 그러나 사람의 모유에서 먼저 배양하지 않고 와타나베토끼의 저밀도 리포단백질을 함유한 배지에서만 배양한 대동맥에서는 훨씬 높은 콜레스테롤 농도를 보여주었다. 이 결과로 미루어 보아 사람의 모유가 대동액내의 콜레스테롤 축척을 막아주는 역할을 한다는 사실을 추측할 수 있다. Milk was tested whether it plays roles as a cholesterol-lowering agent in suckling rabbits since a serum cholesterol content of newborn rabbit was increased till second week then gradually decreased during lactation. Cholesterol content of fetal rabbit aorta was compared after the aorta was cultured in the media containing human breast milk and WHHL (Watanabe heritable hyperlipidemic) rabbit LDL. In precultured aorta in the medium containing milk prior to culture with 5% hyperlipidemic LDL media, the aortic cholesterol content was similar to that of the aorta cultured in the human breast milk only. However, the cholesterol content of the aorta cultured in 5% hyperlipidemic LDL media without preculture in the human breast milk was significantly higher than that of the precultured aorta in the human milk. This suggests that milk led the fetal aorta resistent to cholesterol-elevating effect by an unknown mechanism.

Traditional Medicine (TM) is called as philosophical medicine in Korea. An unified theory named as Sihnsang-hanron (SSHR) was hypothesized through studies of scientific analyses on various theories of TM. SSHR has extracted seven concepts which are six common ones from the great three books (三大原典) and the Logic of Laotzu & Chuangtzu (老莊思想). Six common concepts are the affecting by cold (傷寒), qi (氣), cold or heat (寒熱), exterior & interior of body (表裏), deficiency or excessiveness (虛實), and yin & yang (陰陽). We have tried to apply these seven concepts to Physics and Life Science. The affecting by cold means anti-sunlight and the origin of all diseases. The difference between TM and modern medical science would be in diagnostic methods as well as their theoretical analyses for various diseases. The modern science follows Haeckel's positive dialectics applied by the biological monism, and oriental one(SSHR) does Yin-Yang monism from the studies of Logic of Laotzu (老子) & Chuangtzu (莊子). SSHR would make the theory of exterior & interior of body (表裏論) and six channels (六經) develope scientifically as a diagnostic technique of disease. This theory is an excellent one that can't be found out in modern medical science, and so it should be developed as a scientific theory by using modern mechanic instrument. Chuangtzu asserted that ai was the basic substance of the universe. It is hypothesized that qi (氣) is like small particles -higgs, with dynamic power in modern Physics. We consider cautiously qi could be calculated by mathematics through higgs' bosons in near future.

Three important books in the oriental medicine are Huangjenaekyung (medical book), Sanghanron (pharmacological book) and Shinnongbonchokyung (herbal book). Chang, joong-kyung who is the writer of Sanghanron would be recommended as a saint physician and his book, Sanghanron is granted for a best book in this field by Chinese people. Also, Japanese physicians would estimate Sanghanron as the most magnificent book ever written by a human being. Sanghanron contains a lot of confirmations (證) of diseases, their progressing courses and exact therapeutic ways. Therefore modern physicians and pharmacists who are interested in the oriental medicine might study and practice more scientific approach of therapy for patients. The aim of this bibliographical study on Sanghanron is to explain systematically theories of this book and harmonize them with the modern medicinal study: In this study we have acquired three main results, the first is that we could get the coincidence between western & oriental way on the five therapeutic principles-sweating, vomiting, harmonizing, excreting and bleeding : the second, notice the exclusion of the Five Element Theory(the fundamental one in oriental medicine) and the third, found out the possibility of the immunological and neuroscientific explanation for pharmacological application to the oriental medicine.

From the 1920s to the 1940s, Korean and Chinese pop songs were in full bloom and enjoyed by the public. Recognizing that Korean and Chinese pop music has not been placed on the comparative list of studies together despite their historically close correlation, this study aims to reveal the development patterns of modern pop songs in Korea and China and explore new areas of research. The invasion of Western powers, which began at the end of the 19th century, opened the doors of China, and Korea also began to undergo drastic social changes due to Japanese aggression and colonial rule. In the process of spreading capitalist culture centered on Western Europe and Japan, Korean and Chinese pop music developed into diverse forms through fusion and harmony, not the dichotomy between traditional and foreign styles. In the 1930s, K-pop and Chinese pop developed with the popularity of ‘Shin Minyo’ and ‘Shin Min-ga’ based on their respectively traditional folk songs. In this text, we will look at the musical content of Korea’s “Shin Minyo” and China’s “Shin Min-ga,” which were widely sung in the 1930s and 40s and is an important part of pop music. At Japanese colonial period, 〈ours〉 exist in the two countries pop songs which fill with the public longing and desire, strive to succeed the trails of the traditional folk songs and attach meaning to look at nationalization of pop songs and Popularization and Cultural Phenomenon. In particular, the two genres are have in common with emerging in historical backdrop of the Japanese colonial period, so wo can say, it is a more precious tasks.

공산성, 나 그리고 존재론적 조우 : 미적 체험에 대한 자문화기술지

최명숙(Choi, Myung Sook) 한국미술교육학회 2021 美術敎育論叢 Vol.35 No.4

본 연구는 자문화기술지를 통하여 공산성의 미적 체험에 대한 미술교육적 의미를 찾아보았다. 이를 위해 2020년 6월부터 2021년 9월까지 열 번의 미적 체험이 이루어졌다. 먼저 세 가지 하위 범주인 ① 뼈아픈 성찰 ‘인간의 무지’, ② 이야기 고도(古都) ‘공산성 사람들’, ③ 존재의 미학 ‘백제의 미’를 통해 연구자 나의 미적 체험을 해석적으로 드러냈다. 그리고 두 가지 상위 범주로서 공산성의 미적 체험이 미술교육에 주는 의미를 찾아보았다. 첫째, 우리는 미술을 통해 존재 체험을 할 수 있다. 미적 대상의 존재 진리는 ‘나’라는 인간의 진실한 성찰, 대상과의 대화를 통해 드러난다. 이는 미술교육에서 본질로서 인간의 이해를 하도록, 미술을 통한 존재 체험의 의미를 얻게 한다. 둘째, 미적 체험은 인간 삶의 타고난 위치에서 깊은 차원으로 할 수 있다. 학생들이 나고 자란 지역을 기반으로 한 직접 체험을 확장하고 성찰과 배움이 스스로 일어나도록 격려해주어야 한다. 그리하여 공산성은 세계문화유산이면서 건축 예술작품으로서 그 존재 의미를 갖는다. This study aims to discover the art educational meaning of the aesthetic experience of Gongsanseong through autoethnography. For this study, ten aesthetic experiences have been done from June, 2020 to September, 2021. The researcher s process of aesthetic experience had been interpretively revealed through three subcategories. ① painful reflection ‘human ignorance’, ② the story of the ancient capital ‘people of Gongsanseong’, and ③ The ontological aesthetic ‘beauty of Baekje’. The meaning of the aesthetic experience of Gongsanseong in art education was searched through two upper categories. First, the ontological experience attainted from the art. The truth of the ontological aesthetic object is revealed with the sincere reflection of the human being, ‘I,’ and through a dialogue with the object. In art education, this allows understanding human beings as the essence, and acquiring the meaning of the ontological experience through art. Second, aesthetic experience could be done on a deeper level from the innate place of human life. Students should be encouraged to expand their direct experiences which occur based on their innate place and to have reflections and learnings through personal experiences. Therefore, Gongsanseong has the ontological meaning as a world cultural heritage and a work of architectural art.
