Cryptoccus necoformans는 면역기능이 저하된 환자에서 기회 감염을 일으키는 진균이나 정상인에서도 드물게 질병을 일으킨다. 그러나 임산부에서 폐크립토콕쿠스증을 동반한 크립토콕쿠스 수막염의 보고는 아주 드물다. 저자들은 분만 후에도 악화되는 두통과 의식저하로 내원한 임신 37주의 임산부에서 뇌척수액과 폐조직검사를 통해 폐크립토콕쿠스증을 동반한 크립토콕쿠스 수막뇌염을 진단하고 항진균제를 사용하여 치료하였다. 본 증례처럼 명백한 기저질환이 없는 임산부에서도 크립토콕쿠스 수막염은 발생할 수 있으므로 의심이 되면 뇌척수액검사를 포함한 진단적 검사를 시행하고 적절한 치료를 시작해야한다. 그리고 임산부에서 크립토콕쿠스증이 발생한 경우의 치료에 대하여 문헌 고찰과 함께 보고하는 바이다. Cryptoccocosis occurs more frequently in immunocompromised hosts such as patients with AIDS, lymphoma, leukemia and other debilitating diseases. Pulmonary cryptococcosis can occur in the absence of any recognized immunodeficiency and cryptococcal meningitis can occur rarely during pregnancy. Although it is extremely rare, we encounter the reports of case of cryptococcal pneumonia and combined cryptococcal meningitis during pregnancy. We present here that 36-year-old pregnant woman, who was previously healthy, with cryptococcal meningoencephalitis and cryptococcal pneumonia was treated with amphotericin B and flucytosine. The maternal outcome was favorable, and there is no evidence of congenital infection in the newborn.

각국 장애인차별금지법에서의 고용차별 분석

나운환,정명현,박철현 한국장애인재활협회 2003 재활복지 Vol.7 No.1

본 연구는 한국에 있어 장애인 고용차별을 직접적으로 언급하는 법률들이 있으나 법 적용의 실효성과 구제기관의 설치, 입증책임에 대한 분명한 내용을 규정하는 법률이 없기 때문에 고용차별이 계속적으로 발생하고 있으며, 이를 예방하고 고용차별을 근본적으로 개선하기 위해서는 장애차별법을 제정하고 있는 다른 국가나 국제기구 협약에서의 고용차별 내용과 구제기관 및 차별실태를 비교·분석할 필요성이 있으며, 이를 통해 장애인 노동기본권과 관련된 차별금지 및 구제절차 마련 등 정책의 과제 및 방향성을 제시하고자 하는 것이다 따라서 우리나라고용차별을 규정하고 있는 헌법이나 근로기준법, 직업안정법, 남녀고용평등법, 장애인고용촉진 및 직업재활법에서의 차별의 개념과 내용을 분석, 체계화하였다. 또한 각 국의 차별법률은 고용차별의 범주와 기준에 있어서 대륙법계와 영미법계의 법률이 차이가 있어 미국, 영국 호주의 장애차별법을 비교 대상으로 하였으며 UN이나 ILO 등 국제기구의 각종 인권선언이나 장애와 관련된 협약의 내용들도 분석하였다. 여기서 각국의 차별금지 법률들은 차별내용과 기준, 구제기관, 실태를 분석하였으며 UN이나 ILO의 협약은 차별내용과 기준을 분석한 결과 한국의 장애인 고용차별을 방지하기 위해서는 다음과 같은 방안들이 필요한 것으로 분석 되었다. 첫째, 가칭 장애인차별금지법 제정이 필요하다. 둘째, 장애차별을 법적 조치전에 간편하게 해결할 수 있는 전담위원회나 사무국을 설치할 필요가 있다. 마지막으로 노동시장 진입전이나 노동시장에서 일반국민이나 동료 근로자. 고용주들이 갖는 장애인에 대한 인식은 고용차별을 더욱 어렵게 할 수 있으나 이런 인식과 태도에 관한 차별은 법·제도, 행정적인 조치만으로는 해결되기 어려운 문제이기 때문에 범국민이 참여하는 사회운동을 전개할 필요가 있으며 이 운동의 핵심은 장애인의 사회적 이미지를 개선하는 방향이 되어야 할 것으로 나타났다. The purpose of this paper analyses the degree of labor market discrimination effect on the persons with disabilities and ultimately to suggest more effective ways of discrimination. For the research paper. help-wanted ad in the internet and survey research and comparative studies among nations such as USA, Great Britain, Korea and UN. ILO . The result of this research can be summarized as follows ? 1. Decreasing the employment discrimination of individuals with disability, enact make a Disability Discrimination Act and revised a Labor Law, Education Act and Qualification Act etc. 2. To solve the discrimination of employment, it is needed . to service and program for a preventive against discrimination. 3. It is necessary for the individuals who believe they have been discriminated against by an employer because of their disability to establish committee or task force for employment discrimination charge process. 4. To encourage a social movement and facilitate voluntary compliance with the anti-discrimination taws among employers and the public.

The present study was carried out to investigate the potential acute toxicity of safflower seed by a single oral dose in ICR mice. Twenty animals of each sex were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, and 2,500 mg/kg bodyweight. Mortalities, clinical findings, and body weight changes were found and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects in clinical signs, body weight, and gross findings at any dose tested. The results showed that the single oral administration of safflower seed did not cause any toxic effect at the dose levels of 2,500 mg/kg in rats and the minimal lethal dose was considered to be over 2,500 mg/kg body weight for both sexes.

The third generation cephalosporin is widely used in treatment of spontaneous bacterial peritonitis (SBP). Resistance to the third generation cephalosporin was associated with poor outcome in patients with SBP. Thus it is necessary to know the changes in resistance rate. We planned to investigate retrospectively on resistance rate of the third generation cephalosporin of gram negative bacteria isolated in patients with SBP, who visited Seoul National University Hospital between 1998 and 2006. The Clinical and Laboratory Standards Institute guidelines were applied for antibiotic susceptibility test. A total of 269 consecutive episodes of clinically and microbiologically proven SBP was identified during the study period and 209 cases were caused by gram negative organisms. Among 209 isolates, 22 (10.5%) showed resistance to the third generation cephalosporin. The prevalence of resistance was decreasing during the study period (P=0.014).

접착제 미 사용시 치면열구전색제로서의 유동성 복합레진 평가

권호범,김명진,신철환,김지연,박기태 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.2

본 연구의 목적은 유동성 복합레진을 치면열구전색제로 사용할 수 있는지 여부를 평가하는 것이다. 세 종류의 유동성 복합레진(Filtek Flow, Tetric Flow, Charmfil Flow)과 한 종류의 filled sealant(Ultraseal XT plus)가 사용되었다. 주사전자 현미경을 이용하여 세 종류의 유동성 복합레진 및 filled sealant의 resin tag 형성 양상을 비교하였다. 미세누출 평가를 위해 발거된 사람의 소구치 54개를 각각 18개씩 무작위로 세 군으로 배분하였다. 각 군마다 통상의 filled sealant 와 한 가지씩의 유동성 복합레진을 교합면 열구에 도포하였다. 치아들은 thermocycling(5˚ ± 2℃와 55˚ ± 2℃ 사이에서 30초씩 1200회 시행) 후 48시간 동안 1% methylene blue 용액에 보관하였다. 각각의 치아를 절단하여 미세누출 정도를 관찰하였다. 세 종류의 유동성 복합레진 및 filled sealant는 유사한 resin tag 형성양상을 보였다. 세 종류의 유동성 복합레진은 각각 filled sealant보다 현저히 더 많은 미세누출을 보였다. 세 종류의 유동성 복합레진 간의 미세누출 정도는 유사하였다. 유동성 복합레진은 통상의 filled sealant와 비교해볼 때 보다 많은 미세누출을 야기할 수 있으므로 치면열구전색제로 적절하지 않다. The aims of this study were to determine if flowable composites can be used as pit and fissure sealants without bonding agents. Three flowable composites(Filtek Flow, Tetric Flow, Charmfil Flow) and a filled sealant (Ultraseal XT plus) were used. The pattern of resin tag formation in the four sealant meterials were compared using SEM. For the microleakage assessment, 54 extracted human premolar teeth were randomly divided into 3 groups containing 18 premolars each. In each group, a conventional filled sealant and one of the three flowable composites were applied to occlusal fissures. The teeth were thermocycled(1200 cycles between 5˚± 2℃ and 55˚± 2℃ with a dwell time of 30 seconds) and immersed in a 1% methylene blue solution for 48 hours. Each tooth was sectioned and examined to determine the extent of dye penetration. Three flowable composites and a filled sealant showed a similar resin tag formation pattern. The three flowable composites showed significantly more microleakage in each group than the filled sealant. The level of microleakage was similar in the three flowable composites. Flowable composites are not recommended as pit and fissure sealants because more microleakage can occur even when occlural fissures are mechanically widened.
