Some selected fruit juices and fermented red grape juices were investigated to determine the phenolic components by the Folin-Ciocalteu method and antioxidant capacity using α-α-diphenyl-β-picrylhydrazyl(DPPH) method. Commercial red grape beverages and red wines were also analyzed as control groups. In the juice, kiwi fruit had the highest phenolic components followed by orange(summer), red grape(Cambell Early:Yong-Chun), mandarin orange (autumn), apple(Hong-Ok), cherry tomato, tomato and water melon. Whereas, on the antioxidant efficiency, tomato showed the highest free radical scavenging effect followed by orange(summer), cherry tomato, mandarin orange(autumn), apple(Aori) red grape(Cambell Early:Sung-Ju), kiwi fruit and water melon. The amount of pheonlic components of red wine was 2 times of that of fermented sugar added grape juice, however, the antioxidant efficiency of fermented sugar added grape juice was almost the same as that of red wine. It was found that no clear relationship could be shown between the content of phenolic component and antioxidant capacity of fruit juices and fermented red grape juices. The fruit juices from tomato, orange, cherry tomato, mandarin orange, red grape and fermented sugar added red grape juice showed high free radical scavenging effect and should be regarded as a valuable source of antioxidant.

The purpose of this study was to diagnose the relation among the type of dance major, social backup and stress coping behavior. To achieve the purpose, 232 dance majors from 5 universities in Seoul and metropolitan area were random-sampled. To rate social backup, Interpersonal Relations Perception Questionnaire used by Cohen and Hoberman in 1983 was used. To rate coping behavior on stress, The Ways of Coping Checkiist developed by Folkman and Lazarus in 1985 and translated and standardized by Kim, Jung-hee and Lee, Jang-ho in 1985 was used. For data process, One-way Analysis of Variance and Multiple Regression Model was used. Through these research tool and process, the result as follows were achieved. First, there were partial difference in social backup and stress coping behavior according to demographic variabies. Referring to social backup, the group with higher standard of knowledge generally showed more positive perception of social backup and the group with higher income discerned higher feelings of belonging. Referring to the religion, feeling of belonging to Christianity or Buddhism were higher than that of Catholic or pagan On the matter of stress coping behaviour, the higher grade the group was, the more stress coping behavior were shown and, in many cases, it was problem oriented coping behavior. This tendency is similar according to the amount of income. According to the type of religion, in many cases, probiem-oriented coping behavior and social backup seeking behavior were shown. Second, the more positively the dancer recognize of the dance major activity and the more highly recognize social backup, the more various types of stress coping behavior occurred except for coping behavior with wishful thinking.

Mycobacterium genauense는 최근에 알려진 미코박테륨으로서, 식욕 부진, 체중 감소, 설사, 림프절 병증 등 파종성 Myocobacterium avium-intracellulare complex 감염과 유사한 임상상을 보이며, 위장관 침범을 잘 하는 것으로 알려져 있으나 아직 국내에서 증례는 보고된 바가 없다. 저자들은 진행된 HIV 감염 환자에서 십이지장의 미란성 병변으로 발현한 Mycobacterium genavense 감염 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. 환자는 상복부 동통과 발열, 설사로 내원하였다. 십이지장의 미란성 병변에서 시행한 조직검사에서 항산균이 가득 차있는 거품세포가 관찰되었으며, 이 검체에서 16S rRNA 유전자의 중합연쇄반응 검사를 시행하여 Mycobacterium genavense를 확인하였다. Mycobacterium genavense, first identified in 1990, is known as a pathogen that mimics disseminated Myocobacterium avium-intracellulare complex (MAC) infection with particular propensity for the gastrointestinal tract. In Korea, no case with the organism has been reported. Herein we report a case of Mycobacterium genavense infection that manifested with erosive lesion of duodenum in a patient with acquired immune deficiency syndrome. The patient presented with epigastric pain and fever, diarrhea. Duodenal biopsy showed histiocytic infiltration with numerous acid-fast bacilli. Identification of the mycobacterial isolate by the polymerase chain reaction restriction analysis of 16S rRNA gene revealed Mycobacterium genavense.

To invesitigate the immunoadjuvant effect of Taesanbanseok-san(TBS), TBS was pretreated to Ballb/c mice for 10 days with intraperitioneally. After 10 days, haptenic antigen (VCR-BSA, vincristine-bovine serum albumin) complexed with Freund's complete adjuvant was immunized. The results are as follows. The antibody production in Balb/c mouse immunized with VCR-BSA was markably increased in the pretreated group of TBS compared with saline treated(control) group. The number of macrophage in Balb/c mouse immunized with VCR-BSA was considerably increased about 2.3 times in the pretreated group of TBS compared with control group. The lysozyme activity of macrophage in Balb/c mouse that was immunized with VCR-BSA was increased gradually in the pretreated groups of TBS compared with control group. In the TBS pretreated group, B cell proliferation was increased with a dose dependent manner. At the concentration of twenty microliter/well of TBS, B cell proliferation activity was most highest. On the other hand, in the T proliferation, TBS pretreated group had less considerable activity than B cell proliferation. These results may suggest that TBS will have immunoadjuvant effects on the cells which concerned with immuno mechanism.

This study was performed to develop a standardized recipe for yuza pyun made of citron juice that is by-product of citron tea, to increase the utilization of citron. The effects of mungbean starch(15%, 18%) and dilution ratio of yuza extract(100%, 75%, 50%) on the quality characteristics were evaluated. The quality characteristics of the samples were estimated in terms of sweetness, color difference, texture profile analysis and sensory evaluation. Sweetness of the 18% mungbean groups were higher than 15% groups(p<0.001). The values of Hunter color system indicated that higher content of yuza extract tended to increase yellowness significantly(p<0.001). Texture profiles of hardness, adhesiveness, springiness, cohesiveness, gumminess of yuzapyun showed no significant differences among samples. For sensory evaluation, color and sourness were decreased as yuza extract was diluted, whereas elasticity and sweetness were increased. Yuza pyun containing 18% of mungbean starch with 50% diluted extract was the most preferred in overall acceptability. According to multiple regression analysis, color, sweetness, elasticity and sourness(in order) were important control factors in overall acceptability.

환기정도에 따른 수술실용 신발 종류가 수술실 오염에 미치는 영향 : How to Choose Suitable Shoes?

Background : Various types of protective footwear have been used to minimize bacterial contamination in operating rooms. In recent years, debate has arisen concerning the need for use of such protective footwear. This study was designed to provide useful data about choosing shoes most suitable for the surgical environment. Methods : Between November, 1999 and January, 2000, we performed this experimental study by comparing effect of three types of shoes (i.e., disposable shoescover, operating room-restricted shoes, and ordinary shoes) on bacterial contamination of operating rooms equipped with two different ventilation systems (i.e., high air-change, low air-change) respectively. Data were collected during two-hour sham operations in which subjects and their activities were strictly standardized. Bacterial flora were sampled from the study area floor and air colony-counts were measured. Results : In experiments involving high air-change ventilation system, there was a significant difference of floor contamination between three types of shoes, but no difference of air contamination. Under low air-change system, there was a significant difference of both floor and air contamination between three types of shoes. Conclusion : The results show that protective footwear would be unnecessary in the operating room with high air-change ventilation system, but it is important to choose suitable shoes carefully under low air-change system. Therefore, the use of outdoor shoes can be considered under high air-change system, but it would seem sensible to apply their first use in less bloody operations at the day surgery center or out-patient department to prevent transfer of body fluid into the outside environment.

Amelogenesis imperfecta is a group of hereditary defects of enamel, unassociated with any other generalized defects. It is classified into 14 subtypes according to different clinical and genetic features. According to its clinical features, it is classified into hypoplastic type, hypocalcified type and hypomaturation type. However, these features tend to co-exist often. Dental features associated with amelogenesis imperfecta include quantitative and qualitative enamel deficiencies, pulpal calcification, root malformations, abnormal eruption, impaction of permanent teeth, progressive resorption of root and crown, congenital missing teeth and anterior and posterior open bite occlusions. The first case patient is a 16 month-old child with discoloration of deciduous teeth. All of her deciduous and permanent dentition has shown amelogenesis imperfecta. The restorational, orthodontic and recent prosthodontic treatments have been completed. Another patient is a 9 year and 3 month-old child with amelogenesis imperfects in both deciduous and permanent dentition. The restoration has been done and the prosthodontic treatment is planned after the completion of growth. Above cases indicate that amelogenesis imperfecta occurs both in deciduous and permanent dentition, and it requires the long term treatment and care. 법랑질 형성부전증(amelogenesis imperfecta)은 전신질환과 관련없이 법랑질에 결함을 나타내는 유전질환이다. 법랑질 형성부전증은 발현되는 증상과 유전 양상에 따라 14가지의 아류형으로 분류된다(Witkop, 1989). 임상적으로는 크게 형성부전형(hypoplastic type), 저석회화형(hypocalcified type), 성숙부전형(hypomaturation type)으로 나누어진다. 하지만 이들은 때로 혼재된 양상으로 나타난다. 법랑질 형성부전증은 법랑질이 질적으로나 양적으르 부족하며 치수 석회화, 치근 형태 이상, 맹출 장애와 영구치의 매복, 점진적인 치근의 흡수, 선천적 치아 결손, 그리고 전치부나 구치부의 개교합 등의 문제점을 나타낸다. 첫 번째 증례는 만 1세 4개월때 유전치부의 치아색 이상을 주소로 내원한 환자로 그 후 모든 유치 및 영구치에서 법랑질 형성부전증이 관찰되어 수복 술식, 교정적 치료 및 최근 보철 치료까지 완료하였다. 두 번째 증례는 만 9세 3매월된 환아로 유치 및 영구치에서 법랑질 형성부전증이 관찰되었다. 수복 치료가 시행되었고 보철 치료는 성장 완료 후 시행하기로 계획하였다. 본 증례들을 통하여 법랑질 형성부전증은 유치 및 영구치 모두에 발생할수 있으며 장기간의 치료 및 관리가 필요하다는 것을 알 수 있었다.

양극성 장애 조증과 혼재성 삽화의 치료제로서 Topiramate 단독요법의 항조증 효과와 안정성에 대한 예비 연구

천봉희,권성민,장진열,조성남,조 웅,권도훈 대한생물치료정신의학회 2002 생물치료정신의학 Vol.8 No.2

저자들은 양국성 장애 조중삽화 및 혼재성 삽화의 단독 치료제로서 새로운 항경련제인 topiramate의 항조증 효과와 안정성을 평가하기 위하여 본 연구를 하였다. 양극성 장애 조증 삽화와 혼재성 삽화로 진단이되어 입원을 한 환자 14명(남자 6명, 여자 8명)을 대상으로 topiramate를 단독으로 6주간 투여하였다. Young's Manic Rating Scale(YMRS), Brief Psychotic Rating Scale(BPRS)로 환자들의 증상정도를 평가하였으며, 추가해서 체중변화도 측정하였다. 연구결과, YMRS, BPRS 평균점수 및 체중은 topiramate 치료 전에 비해 6주 치료 후에 유의하게 감소되었다. 또, YMRS 점수가 20미만일 때 조증상태가 안정된 것으로 본다면, 본 연구에서 치료 6주 후 YMRS 점수가 20미만인 환자는 14명 중 7명으로 topiramate의 치료 반응률은 50%라 할 수 있다. 가장 흔한 부작용은 위장관 증상으로서 식욕감퇴, 구역, 설사 등이었으며, 이는 6주 연구 후에 topiramate 치료를 중단하게 하는 원인이었다. 진전이나 이상감각은 대체로 topiramate를 투여한 후 1∼2주 내에 나타났다가 1∼2주 지속된 후 사라졌다. 향후 연구에서는 본 연구의 제한점을 보완하는 대조군 연구가 필요하며, 부작용을 줄이기 위한 보다 적절한 topiramate의 증량방법도 고안되어야만 할 것이다. Objectives : Topiramate is a newly developed anticonvulsant agent with possible mood-stabilizing properties. The purpose of this study is to explore the antimanic efficacy and the tolerability of topiramate as monotherapy in bipolarⅠdisorder, most recent episode manic or mixed. Method : In this study, fourteen hospitalozed patients who met the DSM-Ⅳ criteria for bipolarⅠdisorder, most recent episode manic or mixed were given topiramate monotherapy for up to 6 weeks. The response to topiramate was assessed with Young's Manic Rating Scale(YMRS) and Brief Psychotic Rating Scale(BPRS). Body weight changes were also measured. The Ratings were completed at baseline nad then on 1,2,3,4, and 6 weeks. Results : The mean Young's Manic Rating Scale(YMRS) score improved from 38.36(25-42) at baseline to 22.29(12-37) at the end of the study. The Brief Psychotic Rating Scale(BPRS) score improved from baseline mean of 44.64(35-60) to a last observation of 28.92(13-43). The mean body weight decreased from 62.43kg(47-81kg) to 58.64kg(45-81kg). At the end of study, seven patients scored less than 20 on the YMRS score, three of them were less than 13, Adverse events included anorexia(N=9), nausea(N=6), diarrhea(N=4), paresthesia(N=4), tremor(N=2), and rash(N=1). Conclusion : In this study, the response rate to topiramate was 50% as a treatment agent for bipolarⅠdisorder, most recent episode manic or mixed and topiramate might be associated with weight loss. But the adverse effects such as gastrointestinal sympotoms decreased the compliance of topiramate. Inthe future, double-blind controlled studies are needed to further investigate the antimanic efficacy and tolerability of topiramate.

흡수율을 고려한 폴리아미드의 절삭조건에 관한 연구

김남진,김희남 명지대학교 대학원 1999 대학원논문집 Vol.3 No.-

Nowadays, new and improved plastic materials are being produced due to advancements in the production of composite chemicals. The increased use of these materials has led to the study of new and improved cutting methods. These composite materials consist mainly of nylon resin. There are five types of nylon resin: nylon 6, nylon 66, nylon 12, nylon 46, and MC nylon. Nylon resin is usually molded during production, but the molding of nylon resin results in less accurate measurements. Because of this inaccuracy, the nylon resin must be cut using optimum cutting methods. One major concern, however, is that nylon resin is very sensitive to heat and water absorption. Sumner heat and humidity can cause the deformation of nylon resin and result in inaccuracy during production. In this paper, then I will study the resistance force surface roughness of MC nylon which has absorbed water.

인체의 골수는 간엽모세포를 함유하고 있으며 이들은 골수미세환경의 주된 세포들로 분화가 가능하여 조혈기능을 지지한다. 본 연구에서는 성별이 다른 동종조혈모세포이식 환경에서 조혈모세포의 완전 생착을 보이고, 이식 후 1년에서 8년이 지난 11예의 재생불량성 빈혈 및 백혈병 환자들을 대상으로 하여 골수에서 MSC를 분리하고 체외 확장을 통해 배양된 MSC에서 X 염색체 탐식자를 이용한 FISH 및 microsatellite polymorphism PCR 기법으로 그 기원을 확인하였다. 그 결과 조혈모세포는 완전히 공여자 기원으로 대치되었음에도 불구하고 MSC는 모두 수여자 기원임을 알 수 있어, 동종조혈모세포이식에서 미세환경의 구축은 수여자의 자가 생산에 의한 골수 간질세포에 의한 것으로 생각된다. Background: Human bone marrow (BM) contains mesenchymal stem cells (MSC) that can differentiate into various cells of mesenchymal origin. It remains a matter of controversy whether donor-derived stromal cells are capable of engraftment following hematopoietic stem cell transplantation (HSCT) or not. Methods: To determine if donor-derived stromal cells are transferred to the recipients of allogeneic HSCT, we investigated the characterization of MSC in 11 patients 1 to 8 years after sex mis-matched allogeneic HSCT in severe aplastic anemia and leukemia. Results: All patients had complete engraftment with donor- derived stem cells as shown by detection of donor type DNA in peripheral blood mononuclear cells. Following culture, MSC showed the expression of SH2 and SH4, but none of the hematopoietic markers of CD14, CD34, or CD45. MSC which can be differentiated to osteogenic lineage showed the genotype of recipient completely using FISH or PCR analysis. Conclusion: This study confirmed that MSC isolated from recipients of allogeneic HSCT in severe aplastic anemia and leukemia are not of donor genotype despite of full hematopoietic engraftment with donor type. Donor cells did not contribute to reconstitute the marrow microenvironment.
