성호르몬은 근육의 발달(아나볼릭 효과)에 관여하는 것으로 잘 알려져 왔으며 인체의 치료제로 넓게 사용되고 있다. 돼지고기에는 주로 성선(정소와 난소)에서 생산되어 고기에 축적된 다양한 아나볼릭 효과를 나타내는 성호르몬이 많이 존재하는 것으로 알려져 있다. 따라서 본 연구는 돼지고기에 존재하는 아나볼릭 스테로이드를 추출하여 근육세포의 증식과 분화에 미치는 영향을 파악하고자 실시하였다. 본 연구에서 돼지의 각 조직으로부터 아나볼릭 스테로이드를 추출하는 3가지 방법(M1, M2, M3)을 개발하였다. 3가지 모든 추출방법에서 아나볼릭 스테로이드가 추출되었으며 특히 M3에서 조직 1g당 가장 많은 양을 획득할 수 있었다. M3를 이용하여 아나볼릭 스테로이드를 추출했을 때 돼지고기의 근육과 지방에서는 스테로이드 호르몬 양이 수컷에서 가장 높았고, 혈청에서는 nandrolone 과 testosterone의 양은 수컷에서 가장 높았으며, estrone와 $17{\beta}$-estradiol의 양은 비슷하였다. 근육세포 증식은 돼지 아나볼릭 스테로이드의 농도 의존적으로 촉진되었으며, M3에서 가장 빠르게 증식되었다. 근육세포의 분화는 추출된 아나볼릭 스테로이드 처리구가 대조구보다 더 효과적으로 분화가 잘 되는 것을 세포 모양과 유전자(AR, myoD, desmin, myogenin)를 통하여 확인할 수 있었다. 특히 M3에서 추출된 아나볼릭 스테로이드에서 myogenin과 AR 유전자가 유의적으로 높게 발현되었다(p<0.001). 전체적으로 돼지의 아나볼릭 스테로이드는 근육세포의 성장과 분화를 촉진하였다. 따라서 돼지고기에 있는 아나볼릭 스테로이드의 섭취를 통해 인체 근육의 성장과 발달에 긍정적 효과를 나타낼 수 있을 것으로 사료된다.

본 연구에서는 엉겅퀴 추출물(CE) 및 엉겅퀴 발효추출물(FCE)이 남성 갱년기 증상의 개선에 미치는 영향을 알아보기 위해 25주령 된 흰쥐에 추출물을 6주간 투여한 후, 간독성, 테스토스테론, SHBG, 정자수 및 정자 운동성, PSA, 복부지방, 근육량, 혈중지질, 운동수행능력 등에 미치는 영향을 조사하였고 세포 실험을 통해 그 기작을 확인하였다. 천연 추출물에서 있을 수 있는 간독성을 측정하기 위해 간 손상의 지표인 AST와 ALT를 측정한 결과 대조군과 차이를 보이지 않았다. CE 및 FCE 투여 후 남성 갱년기에서 감소하는 테스토스테론의 혈중 농도가 증가하였고, 테스토스테론의 생체 내 활성을 저하시키는 SHBG의 농도는 반대로 감소하였다. 총 정자수와 정자 운동성을 측정한 결과에서도 CE 및 FCE 투여군에서 증가한 양상을 나타냈고, 이는 정자 형성과 활동성에 영향을 주는 테스토스테론 농도의 증가와 관련이 있을 것으로 생각된다. 또한, 전립선에 대한 부작용을 알아보기 위해 PSA를 측정하였으나 대조군과 별다른 차이를 나타내지 않았다. 지방조직과 근육에 대한 영향을 측정한 결과 지방조직량은 줄이고 근육량은 늘려 남성 갱년기에서 흔히 나타나는 체지방 증가 및 근육량 감소를 완화시키는 효과가 있는 것으로 생각된다. 또한, 남성 갱년기에서 흔히 동반되는 혈중지질대사 이상에 있어서도 CE 및 FCE 투여군이 총 콜레스테롤과 중성지방은 감소시킨 반면 고밀도 콜레스테롤은 증가시켜 긍정적인 효과가 있는 것을 관찰하였다. 운동수행능력 측정 결과에서는 CE 및 FCE 투여군이 대조군보다 수영시간이 증가하였고, 이는 CE 및 FCE의 투여가 남성 갱년기에서 나타나는 활력의 저하를 회복시킬 수 있음을 시사한다. 끝으로 CE 및 FCE의 테스토스테론 증가기작을 알아보기 위해 세포실험을 통해 테스토스테론 생합성 과정에 관여하는 효소 유전자의 변화를 측정한 결과 처리군에서 합성관련 효소는 모두 증가함을 나타내었고, 전환 관련 효소는 감소함을 나타내었으므로 엉겅퀴 추출물이 테스토스테론 합성을 직접 촉진시킬 수 있음을 알 수 있었다. 또한, CE와 FCE를 비교해 봤을 때 전반적으로 FCE가 더 좋은 효과를 나타내었고, 이는 발효 과정을 통해 엉겅퀴 유효 성분의 증가에 따른 것으로 여겨진다. 결론적으로 본 연구에서는 CE 및 FCE가 남성 갱년기 개선에 도움을 줄 수 있는 좋은 소재로 활용될 수 있다는 가능성을 제시하였다.

배경: 위장관 간질성 종양(GISTs)은 위장관계에 발생하는 간엽성 종양이다. 위장관 간질성 종양은 면역조직화학 검사에서 c-kit 단백 발현의 양성을 나타내며 그 임상적 경과는 매우 다양하다. 저자들은 위장관 간질성 종양의 임상병리학적 특성을 고찰하고 예후 인자를 평가하기 위하여 후향적 연구를 시행하였다. 대상 및 방법: 본 연구는 고려대학교 의과대학 외과학교실에서 1996년부터 2003년까지 위장관 간질성 종양으로 수술적 절제를 시행한 40명의 환자를 대상으로 하였다. 종양의 크기와 핵분열 정도에 따라 저위험도 집단(23예), 고위험도 집단(17예)으로 분류하였으며 두 군간 임상병리학적 특성, 면역조직화학 검사 결과 및 예후를 비교 분석하였다. 결과: 환자의 평균 연령은 $61.3\pm11.1$세이었으며 남녀비는 1:1,1이었다. 임상병리학적 소견으로는 수술 전 임상 증상이 있었던 경우와 수술 전에 조직학적으로 진단이 되었던 경우, 종양의 크기가 클수록, 핵분열이 많을수록, 종양의 성상이 궤양을 동반하거나 괴사를 보일 때, 고위험군에 포함되는 빈도가 높았다. 단변량 분석 결과, 종양의 크기, 핵분열 정도, 궤양 및 괴사 소견 그리고 내시경적 초음파 이상소견이 통계학적으로 의미가 있는 인자들로 나타났으며, 다변량 분석을 시행한 결과 핵분열 정도가 생존율에 영향을 미치는 독립적인 예후 인자로 나타났다. 관찰 기간 중 8예에서 재발하였으며 STI-571(imatinib mesylate, $Gleeveo^{R}$)을 사용한 4예는 현재까지 생존하고 있으며 사용하지 않은 4예 중 2예는 질환이 진행하는 양상을 나타내었고, 나머지 2P는 사망하였다. 결론: 위에서 기원한 위장관 간질성 종양에서 종양의 크기, 궤양 및 괴사 소견은 생존율에 영향을 주는 임상병리학적 소견이며, 핵분열 정도는 유용한 예후 인자라고 할 수 있다. STI-571은 재발 혹은 전이 환자에 있어 치료 효과를 나타내므로 술후 치료에 적용하는 것이 예후 향상에 기여하리라 생각된다.

This study was attempted to contribute to the development of school health by providing the basic data about the distribution basis and distribution aspect of teachers holding additional school health that are in charge of school health business in parimary schools, middle schools and high schools without any nurse-teacher. This study analyzed literatures about the history, related laws, organization and professional manpower of school health. The emphasis was set on the distribution basis of theachers holding additional school health. The results of this study are as following: 1. The school health of the world dates to the late 18th century in Europe where was free supplying with food for poor children. The school health of Korea orginated from smallpox vaccination which was executed with appearance of modern schools in the late 19th century. 2. The related laws of school health began as a part of Education Law with was constituted in 1949. By the School Health Law constituted in 1967 and the enforcement ordinance of School Health made firm the legal basis of school health. 3. The administrative organs of school health are the Ministry of Education in center and each Board of Education in cities and provinces. For the first time in 1979, the department of school health was established in the organization of the Ministry of Education. And at about the same time of establishment of the department of school health, health section was established in the department of social physical-training in locality. 4. In the manpower of school health which was presented in the related statute of school health, there are the ward chief of education, the superintendent of educational affair, of cities and districts, the mayors, the governors of provinces, the school managers, the principals, the school doctors, the school pharmacists, and the nurse-teachers, including teachers holding additional school health as the practical manpower of school health. 5. In order to get some information on distribution aspect of teachers additional school health, this study made up a questionnaire from August 3 to August 11, 1988. The subjects of this study were 212 leachers who took part in the yearly training for teachers holding additional school health from Kyunggi province, Chungbuk province and Jeonbuk province. The results of the questionnaire are as following: 1. The distribution percentages of teachers holding additional school health according to each Board of Education wich schools are subject to, are as following:70.1% (Kyunggi), 76.5% (Chungbuk), and 81.4% (Jeonbuk). There was a significant difference. The distribution percentages of teachers holding additional school health according to the school levels of 3 provinces are as following: 74.1% (Primary schools), 77.8% (Middle schools), 76.7% (High schools). There were little significant differences. 2. The distribution according to the general characteristics of the subject schools: There were 64.2 percent of primary schools and 35.8 percent of middle schools among 212 schools. 91. 5 percent of schools were located in districts. Public schools formed 55.7% and then national schools were higher in percentage than private schools. 58.5 percent of schools had 1-9 classes, 64.6 percent of schools had 101-500 students, and 90 percents of schools had 1-20 teachers. In considering student sex, the coed school showed the high distribution percentage (Primary schools : 100%, Middle schools: 81.6%). 3. The distribution according to the characteristics of teachers holding additional school health: 93.3 percent of teachers were female, and more than 60 percent of teachers were 20-29 years old. As the age got higher, the percentage became lower. There were little significant differences by marital status. In considering their educational status, 86.8 percent of teachers in primary schools were from teacher's colleges, and 64.5 percent of teachers in middle schools were from education colleges. In considering teaching career, 46.7 percent of teachers had teaching career of less than 2 years. 73.6 percent of teachers had held additional school health for less than one year. More than 80 percent of teachers had participated in the training one time or twice. More than 70 percent of teachers had 1-2 additional jobs except for the school health business. The motivation to hold additional school health is most caused by mandatory order, which accounts for more than 80.0 percent. In considering interesting degree concerning school health, lukewarm answer is the highest of 62.7 percent, followed by affirmative answer of 23.6 percent. In considering their contentment degree respecting additional school health job, "discontent or very discontent"is the highest of 47.6 percent. As a descontent reason of additional school health job, overwork is the highest factor of 37.9 percent. Among addiitional school health job, the most difficult affair is nursing service to be 34.0 percent, followed by health education of 31.6 percent. It testify the need of professional. The source of knowledge about school health has been acquired from masscommunication or private health experience, which account for as much as 56.1 percent. It shows seriousness of lack of professionalism. With regard to neccessity of school health experts, 95.8 percent represents absolute need. With above consideration of study results, I propose as follows : 1. I propose that the authorities concerned unify and improve statute respecting current school health which has not been steadfastly supporting school health business by ambiguity of expression and dualization. 2. I propose that the authorities concerned give the school manager, school staffs and parents of students educational chance with which they can acknowledge the importance of school health and in which they can participate as well as set up alternative policy plan to be albe to vitalize school health committee. 3. I propose that administrative organization practicable to taking totally charge of school health business is established within the Ministry of Education. 4. I propose that the authorities concerned back up and cooperate in an attempt by make school health better and desirable toward development by way of appointing qualitied health teachers on the basis of legally regular teacher staffs.

Under the full consideration of the growing need and importance of population education in the field of home economics in Korea, the study was carried out to verify and assess the following facts on the current issues of population education of home economists who are presently engaging in teaching professions as the teachers of middle and high school and professors of college and universities by setting its primary objectives of the study as followings; 1) to assess the degree of general knowledge and attitudes of home economists toward population education in the field of home economics, 2) to verify the problems encountered in implementing population education by home economists in its field, 3) to find an existing status of previous trainings received and other activities of population education of home economists aimed at utilizing these findings as a part of reference materials when the population education is conducted in the field of home economics. In order to attain these objectives described above, the questionnaire was carefully designed to house a total of 40 questions with good combination of multiple-choice and the simple answer questions. The mail questionnaire survey was conducted by establishing teachers of home economics at middle/high schools and college/universities as Senior Home Economists(SHE) who are from public, private liberal arts and vocational schools. The rate of response observed during the survey was 45.6 percent and the findings of the survey research are as follows: 1) Examining the status of the respondents by residence and religion, it was found that 45 percent of middle & high school teachers ar.d 59. 1 percent of college professors are residing in Seoul city area and that the largest percent of them are christian in their religion. Analyzing respondents by their ages, 56 percent of middle/high school teachers are in their 30s, 45 percent of college professors are in their 40s, and 37 percent of college teachers are in their 30s. In addition, 13 percent of the total respondents are found to be unmarried. The study also revealed that 71 percent of the college professors finished Master Degree course and 82 percent of middle/high school teachers are graduated from college level lasting 4 years. Looking over the status cf major fields of respondents, 68.4 percent of middle/high school teachers are specialized in home economic education and the college professors, on the other hand, show relatively even prortion by specializing in the order of food & nutrition science, clothes & textile science and home managerial science. As far as the length of teaching experience is concerned, a relatively longer period of teaching experience is observed in the college professors in comparison with that of middle/high school teachers. In other words, 33.3 percent of middle/high school teachers are experienced in teaching from 6 to 10 years on average while 43.9 percent of college professors show more than 16 years of experience. 2) Examining the status of existing number of children cf the respondents, one boy and one daughter pattern is predominant, showing 28.5 percent in middle/high school teachers and 21.1 percent in college professors. As for the desired number of children of unmarried respondents, it is observed that 43.8 percent of middle/high school teachers desire to have one boy and one girl, and 31.3 percent of college professors want to have one child regardless of the sex. By assessing the degree of awareness of the population education through their students, it is observed that 53 percent of middle/high school teachers and 50 percent of college professors are aware of population education in some extent and that a majority of respondents took the positive attitudes toward an inclusion of family planning components into the formal school education. Another noteworthy to observe is that a total of 84.8 percent out of middle/high school teachers pointed that the population education currently conducted at schools as a part of home economics are less sufficient than it should be. 3) Analyzing the tendency as to whether the respondents were experienced in receiving population education during the time when they were students, 75 percent of college professors and 59 percent of middle/high school teachers responded negative answers in the survey. In the mean time, a total of 50 percent of the respondents replied that they began to acknowledge the importance of population education mainly through the participation of some sort of population-education orientend seminars, experienced by 40 percent of college professors and 80 percent of middle/high school teachers. 4) What it calls attention in this study was to find that 96.5 percent of middle/high school teachers and 72 percent of college professors conduct population education to some extent during their lecture hours and that more than 80 percent of them are never experienced in teaching population and family planning contents in their regular classes. It is, on the other hand, found that no more than once was the response of those who believe themselves that they are experienced in teaching these relevant components to their students. Analyzing the contents of the subjects being taught in the class, a large percent of them are found to be consisted of population and family planning contents. According to this study, the current population education through the formal school is quite inactive. Analyzing the facts, 44.9 percent of the college professors responded that the population and family planning components are quite apart from their specialization which eventually generates lack of interest in the field. 5) It is also noticed through the study that the degree of frequency of commenting on population and family planning contents during the classes was depending significantly on their specializations which means that the degree of frequency varies from a major to another. Those who majored in home managerial science was the first one, as compared to others who majored in different specializations. Glancing over the status of correlations between ages of the respondents and numbers of seminar paticipation, it is quite clear that the aged group participated more than the younger group did, and that the most highest number of participations made by college professors were those who are in 50s. In addition, it is also found that those who are aged 20s and 60s of the respondents were the group who comments least on the contents of population and family planning at their classes. The suggestions and recommendation made through this survey research are as follows. 1) No one denies that the rapid increase of population, as compared to the limited size of land and resources, will certainly affect adversly to an enhancement of individual life quality which will, eventually, bring forth the poverty of the nation. This is the reasson why we are insisting that the world population be controlled up to an optimum level with a matter of global concerns. It is our understading that the primary aim for reducing number of population is believed to be attained only by conducting the systematic and comprehensive population education through the formal schools. Therefore, the role of home economists in the field of population/family planning education is considered very importment due to the fact that an ultimate goal of population education is placed in elevating the quality of family life by having optimum number of children through family planning program. 2) It is quite clear that home economists as teachers of formal school in all level are invited to pay their attention on redefining the ultimate goal of education and that of population education. We also understant that the primary objective of population education is to change the norm and value of the clients by replenishing the students with pertinent knowledge and attitudes on population and its related problems through a sort of education in order to attain the ultimate goal for enhancing the quality of life. There is no exception in the theory of home economics. An altimate goal of home economics is to elevate the general quality of life through an establishment of value existed in daily life. Considering the relations between population education and home economics, it is quite indespensable to bandle population components as an integral part in the field of home economics. We believe, therefore, that the senior home economists positive participation in the effort population control is more needed than it has been. 3) It is also strongly urged that population education should be a part of instructor training course for home economics. In other words, the teacher of home economics should be well aware of population and its problems by teaching interrelationship between population education and home economics, needs, contents and methods of population education during the instructor training courese for home economics. In addition, the senior home economists should be encouraged through positive participation on the short term training by types of domestic and international seminar, workshop, etc. 4) We certainly believe that the population education can not sustain itself without any backing-up of information and findings' of various and comprehensive researches of natural and social sciences. Accordingly, every senior home economist is invited to exert their maximum effort to conduct systematic study with an aim to utilize these findings and information at best in population education in the field of home economics. Therefore, we consider that the development of training material is imminent in order to provide effective and efficient population education through the for training of home economies. It should be noted that these training materials must be carefully designed, tailored and developed to meet the different classes of trainees under the considerations as to whether it is easily adaptable and infusable into the curricula of every field of home economics, and it is acceptable in the degree of difficulty and quality in its contents. 5) It is true that there are many domestic and international research rapers, reports and findings in the field of population education and family planning. However, there is a tendency that the most of research papers are heavily relying on the authors intension and preferences in its expression and publication. Under these circumstances, it is urged that the home economists should aware of the growing need of the technical training in order to keep these available information and research findings reprocessed and redesigned to insure the practical application into the population education in the field of home economics in Korea.
