목적: 후방십자인대 단독 손상 환자에 있어서 보존적 치료를 시행 후 결과를 알아보고자 하였다. 재료 및 방법: 1999년 8월부터 2001년 12월까지 본원에 내원 하여 후방십자인대 단독 손상으로 진단된 11례에 대해서 보존적 치료를 시행하였다. 초기 진단은 이학적 검사와 Telos 기구를 이용한 후방전위 사진(push stress view)으로 하였고 추시 평가는 전향적으로 하였으며 6주, 3개월, 6개월, 1년, 그 후 매년마다 이학적 검사와 International Knee Documentation Committee(IKDC) score와 Orthopadishe Arbeitsguppe Knie(OAK) score를 이용한 임상적 평가를 하는 것을 기준으로 하였으며 6개월 후에는 후방 전위 사진과 단순 전후 및 좌우 방사선을 시행하였다. 치료방법은 6주간 슬관절 완전 신전 상태로 후방 전위 방지 지지대를 부착한 하지 부목 후 6주간 슬관절 후방 전위 방지 보조기를 시행하였다. 이들의 평균 추시 시간은 17.5개월(7~35)이었다. 결과: 11례중 2례에서는 후방전위에 후 외측 회전 불안정성 동반이 발견되어 수술적 치료를 시행하였으며 보존적 치료를 유지하였던 9례에서는 최근 추시 임상적 평가에서 OAK score상 평균 93.2점, IKDC score상 A가 5례, B가 4례이었다. 결론: 동반손상이 없는 후방십자인대 단독 손상에 있어서 보존적 치료가 일차적 치료 방법으로 생각되며 향후 불안정성의 진행과 이차적 퇴행성관절염의 발생 여부 및 상관 관계에 대해서 장기적 추시 관찰 예정이다. Purpose: We assessed prospectively the results of acute, isolated, posterior cruciate ligament injuries treated conservatively. Materials and Methods: Between August 1999 and December 2001, the study population consited of 11 patients. The patients were treated conservatively and were prescribed full extension long leg splint with posterior tibial support for 6 weeks and then posterior tibial support brace for another 6 weeks. Patients completed a sujetive and objective evaluation at 6 weeks, 3 month, 6 month and each year for an average of 17.5 months. Results: Two patients underwent reconstructive surgery because of combined posterolateral rotatory instability. The nine patients were treated conservatively, the mean Orthopadishe Arbeitsguppe Knie score was 93.2 points. International Knee Documentation Committee score in 5 patients was A and 4 patients was B. Conclusion: Our study suggests that patients with acute, isolated posterior cruciate ligament injuries treated conservatively may get good clinical results, but we are planning a long term follow-up evaluation to reveal change in laxity, incidence of arthrosis and their correlation.

연구목적 : 청소년을 대상으로 장애가 있는 식이태도 및 식이행동과 관련된 요인들에서 인종과 문화적 차이가 있는가를 보는 것이다. 방 법 : 1996년도에 3129명의 중고등학교 남녀 학생을 대상으로 학교 장면에서 신체 계측과 설문지를 통하여 수집하였으며 연령은 13세부터 16세 사이의 학생들로 분포되었다. 학생들의 분포는 서울 지역의 663명, 양평 지역의 821명, 조선족이 사는 연길 지역의 830명 그리고 한족이 사는 길림 지역의 815명이었으며, 그들은 모두 키, 몸무게, 신체질량지수, 부모의 수입, 아버지의 학력, 체중조절 설문지, 신체상 척도 및 식이태도검사 등의 내용을 완성하였다. 결 과 : 신체질량지수(BMI)에서는 지역, 성별, 사회경제적 상태에 따른 차이가 없었다. 연길과 길림 지역의 학생들이 서울과 양평 지역의 학생들보다 심한 저체중과 심한 과체중을 갖는 학생들이 많았다. 연길과 길림 지역의 학생들이 서울과 양평의 학생들보다 식이태도검사(EAT-26)의 평균치가 높아 식이태도와 식이행동이 나빴다. EAT-26의 20점 이상인 식이장애의 고위험군은 연길 지역의 학생이 6.9%로 네 집단 중에서 가장 많았다. 한국의 양평지역과 서울 지역의 학생들이 신체상 척도(BIS)의 평균치가 연길 지역과 길림 지역의 학생들보다 의미있게 높았다. 즉 한국의 학생들이 중국의 학생들보다 자신의 신체에 대하여 부정적인 생각을 갖고 있었다. 체중조절 행동의 유병율은 서울 지역 학생들이 26.7%, 양평 지역 학생들이 23.2%, 연길 지역 학생들이 10.6%, 그리고 길림 지역 학생들이 4.6%이었다. 식이조절과 운동은 한국의 학생들이, 식이조절과 약물사용은 중국의 학생들이 가장 많이 하는 방법이었다. 결 론 : 본 연구를 통하여 한국과 중국에서도 식이장애가 결코 적지 않을 것이라는 사실을 확인하였고, 식이장애는 인종과 사회문화적 요인에 의해 크게 영향을 받는다는 것, 마지막으로 식이태도와 식이행동 및 그와 관련된 요인들을 통해서 네 지역간의 문화전이 상태를 확인할 수 있었다. Objectives : The goal of this research was to attempt to examine ethnic and cultural differences in factors associated with disordered eating attitudes and behaviors. Methods : Data were collected from the four groups of 3,129 high school students aged between 13 and 16 years who completed school-based survey conducted in 1996. The students (663 Korean urban, 821 Korean rural, 830 Korean-Chinese and 815 Chinese adolescents) completed an instrument which assessed weight, height, Body Mass Index(BMI), parental income, father's level of education, weight control questionnaire, Body Image Scale(BIS), and eating attitudes and behaviors using the Eating Attitude Test-26(EAT-26). Results : BMI did not vary significantly by race, sex, and socioeconomic status. There were many severely underweight and severely overweight students among Korean-Chinese and Chinese than among Korean urban and Koran rural students. The EAT-26 mean scores of Korean-Chinese and Chinese subjects were significantly higher than those of Korean urban and Korean rural subjects. The EAT-26 mean score of Korean-Chinese was the highest among the four racial groups. The prevalence of high risk EAT-26(EAT-26≥20) students of Korean-Chinese was 6.9% which was the highest among the four groups. The BIS mean scores of Korean rural and Korean urban subjects were significantly higher than those of Korean-Chinese and Chinese subjects. The Korean subjects were more dissatisfied with their body than the Chinese. The prevalences of weight control behaviors were 26.7% in Korean urban, 23.2% in Korean rural, 10.6% in Korean-Chinese, and 4.6% in Chinese subjects. Dieting and exercise were most popular for weight reducing in Korean subjects. Dieting and drug use were most popular in Chinese subjects. Conclusion : These data suggest that there must be many eating disorder patients in Korea and China, and the eating attitudes and behaviors are influenced by ethnic and cultural factors. Implications for understanding sociocultural influence on eating attitudes and behaviors and acculturation are discussed.

항암제(Adriamycin, Cyclophosphamide, 5-Fluorouracil)로 유발된 흰쥐의 간독성에 대한 Squalene의 효과

최영복,김종세,윤중식 조선대학교 기초과학연구소 1998 自然科學硏究 Vol.21 No.1

The objective of the present study was to investigate the cytotoxicity of Adriamycin〔ADM〕. Cyclophosphamide〔CP〕, 5-Fluorouracil〔5-FU〕 in mouse liver cells (group A, B, c), and the protective effect of squalene to the hepatocytes to which ADM, CP, and 5-Fu-induced cytotoxicity(group A-1, B-1, C-1) was examined by transmission electron microscope. In the group A, The cisternae of rough endolplasmic reticulum(RER) and smooth endoplasmic reticulum(SER) are dilated/disoriented at 24 hours and 48 hours. The inner and outer membrane of mitochondria are detached or destructed, and attached ribosomes of RER are diminished in number. The cisternae of the SER are dilated, and the cristae of mitochondria are disrupted at 72 hours and 96 hours. In the group A-1, the cisternae of the RER and the SER are dilated at 24 hours. The cisternae of the SER are dilated at 48 hours. The cell organelles of hepatocytes are recovered from cytotoxicity at 72 hours. At 96 hours, hepatocytes were simillar to those of normal hepatocytes. In the group B, the cisternae of RER were partially destructed and attached ribosomes were remarkable decreased at 24 hours. A number of the mitochondria were dilated and increased in number, the filamentous materials also detected at 72 hours. In the group B-1, the difference between the normal and the treated groups were not detected at 24 hours, but the few mitochondria were expanded at the 72 hours. In the group C, the nucleus was destroyed at 24 hours and 48 hours group, however, somewhat repaired at 72 hours group. The dilated inner cavity and the irregular lamellae of the RER were observed continually until 72 hours group. The inner cavity of the SER were dilated in all groups. However, the destroyed and the normal membrane were observed simultaneously at 72 hours group. The inner membrane of the mitochondria were almost repaired at 96 hours group. In the group C-1, the nucleus was a little finfluenced by the toxicity of 5-Fu at 24 hours and 48 hours, RER were observed to keep the typical lamella structure of cisternae from 24 to 72 hours group, but inner cavity kept on dilating. In SER, inner cavity were also observed to flatten from 24 to 72 hours group. Mitochondria were always shown normal. All cell organelles were similar to those of normal at 96 hours. Accordingly, it can be said that the treatment of SQ prevents the cytotoxicity of ADM, CP, 5-FU on cell organelles of liver cell and that is concerned with the formation of membrane system of cell organelles.

K_(2)O · B_(2)O_(3) · V_(2)O_(5) 계 유리의 조성비에 따른 밀도, 굴절율, 전이온도, 천이금속이온비율 등과 직류 전기 성질을 100~450K 온도영역에서 연구하였다. 실험결과를 비정질 반도체에 관한 전기전도에 대한 이론 모델을 이용하여 분석하였다. 고온 영역에서는 직류전도도의 온도 의존성을 Mott의 포논-도움껑충뛰기 전도모델로 분석할 수 있었다. 활성화에너지는 0.28~0.33 eV로 시료내 V_(2)O_(5) 의 양이 증가할수록 감소하는 경향을 보인다. 저온 영역에서 직류 전기전도도는 Mott의 가변거리 껑충뛰기(variable-range hopping)전기전도도와 잘 일치하며, N(E_(F))값은 국지화 상태에서와 같다. The dc conductivity of K_(2)O-B_(2)O_(3)-V_(2)O_(5) glasses has been investigated in the temperature range 100~450K and physical parameters such as density, refractive indices, glass transition temperature and fraction of reduced transition-metal ion, were observed for various compositions. The experimental results are analyzed with reference to theoretical models proposed for electrical conduction in amorphous semiconductors. The analysis shows that at high temperature region the temperature dependence of the dc conductivity is consistent with Mott's model of phonon-assisted hopping of small polarons. The values of activation energy are 0.28~0.33 eV and decrease with increasing V_(2)O_(5) content in the sample. The lowtemperature dc conductivity data can be well fitted to Mott's variable-range hopping conductivity and the values of N(E_(F)) are also reasonable for localized states.

The purpose of this study was to compare kinematics of the skilled group with the corresponding of the unskilled group during the leap of the mordern dance and to investigate the effective movement patterns of the leap. The kinematic and temporal variables examined using the DLT(Direct Linear Transformation) method of three-dimensional cinematography were leap time, leap distance, leap height and body segment angles at the instants of take off, peak height and touch down. Four skilled and four unskilled groups were selected as the subjects. Two 16mm high speed cameras were used to monitor the subjects’movement patterns. T-test was used to determine if there is any significant (p<0.05) differences on kinematic variables between the skilled and unskilled groups. The conclusions obtained from the analyzed data were as follows; (1) There were not any significant differences between two groups for the angles of body segment at the instant of take off and leap distance. (2) At the instant of peak height, the leap angle and the left ankle angle for the skilled groups were larger than for unskilled groups. (3) At the instant of touch down, the trunk angle in the sagittal plane for the skilled groups were larger than for unskilled groups. (4) The flight time and height for the skilled groups were longer and higher than for the unskilled groups.

송재영,이중복,현방훈,박종현,김병한,권창희,전무형,안수환 충남대학교 생물공학연구소 1993 생물공학연구지 Vol.3 No.-

The g Ⅲ gene located in U_L region of Yangsan strain, a field isolate of Aujeszky's disease virus (ADV) in Korea, was cloned into pTZ18R and sequenced. The gⅢ gene consisting of 1,437 nucleotides showed 98% sequence homology with that of Becker strain, a reference strain of ADV. The gene encoding gⅢ of Yangsan strain was placed under the control of Autographa californica nucleopolyhedrosis virus (AcNPV) polyhedrin promoter, and expressed by the derived recombinant baculovirus using Spodoptera frugiperda 9 (Sf9) cells. The expressed gⅢ was a protein with molecular weight of 72kd determined by immunoprecipitation and Western blotting assay using anti-ADV polyclonal antibodies and anti-gⅢ monoclonal antibody. The partially purified gⅢ protein was utilized as antigen in the radial immunodiffusion enzyme assay (RIDEA) to detect to specific antibody against ADV in pig sera. The results indicated that the sensitivity of RIDEA with the recombinant gⅢ protein antigen (98%) was as high as that with the conventional glycoprotein antigen extracted from the ADV infected cells. In addition, the false positive and false nagative reactions in gⅢ RIDEA were significantly reduced than the conventional glycoprotein RIDEA as judged from the results of standard serum neutralization test.
