The causes of pyogenic liver abscess has been known as biliary tract disease or intrabadominal infection but the large proportions of the patients has no apparent underlying disorders. Recently colonic mucosal lesions were reported in patients with cryptogenic liver abscess and it has been suggested that colonic mucosal break may play a role in developing liver abscess in otherwise healthy patients. We experienced a patient of severe recurrent liver abscess complicated with endophthalmitis only 3 months after successful treatment of initial cryptogenic liver abscess and a polypoid colon cancer was discovered by chance. It seems prudent to proceed colonoscopic examination in patients with cryptogenic liver abscess especially when it is recurrent.

1. 식물유래 약용물질 (PMP)은 살아있는 식물에서 생산된 치료용 단백질로, 발효조에서 세포계통을 이용하는 것보다 적은 비용으로 높은 순도의 단백질을 생산할 수 있어 이에 대한 연구개발이 확대될 전망이다. 2. 식물유래 약용물질의 재배시험을 감독하는 주관부서는 미농무부(USDA)의 동식물 검역청(APHIS)이다. 3. PMP의 생산에는 알팔파. 옥수수, 벼 잇꽃과 담배 등이 이용되고 있다. 4. 현재 상업화된 PMP는 없으나 ProdiGene, Inc사 등 몇몇 생명공학 회사에서 이들의 연구개발이 진행되고 있다. 5. 2002년에 PMP 재배시험은 130에이커 규모로 34개 시험장에서 20건이 허가 되었으며 주별로는 애리조나, 네브라스카 등 14주에서 시험이 이루어 졌다. 6. 미국 USDA의 PMP 재배 지침에 의하면 PMP의 재배생산에는 안전성확보를 위한 별도의 전용장비를 필요로 하며 파종에서 생산까지 엄격하게 관리된다. 7. 미국 USDA의 APHIS는 2002년 PMP 옥수수를 생산하는 ProdiGene, Inc사에 대하여 2건의 포장시험허가 위반사항을 적발하여 벌금 조치를 한바있다. Plant-made pharmaceuticals(PMPs) are therapeutic agents(pharmaceutical proteins) produced in genetically engineered plants. To yield these valuable products plants offer several advantages that include large-scale production capacity at a reduced cost, equivalent purity/activity to other manufacturing systems, and freedom from contamination with animal pathogens, prions, or disease-causing germs. But there are risks of contamination of the food supply and unintended effects on ecosystems. In the U.S. PMPs are regulated under stringent requirement of the U.S. Department of Agriculture(USDA) and the Food and Drug Administration(FDA). In this article, contamination incident with PMP corn engineered by ProdiGene, Inc will be briefly introduced and regulations of PMPs will be discussed.

안수경,김영태,전헌선,정동일,한현민 국립특수교육원 2005 연구보고서 Vol.- No.5

본 연구는 2005년 3월 특수교육진흥법 개정에 의하여 특수학교 치료교육교사의 확대배치 및 일반학교 특수학급에의 치료교육 담당교원 배치 등 치료교육 분야의 발전이 예상되는 가운데, 개정법률이 실제 교육현장에 보다 실효성있게 적용되기 위하여 우리나라 특수교육 공교육 상에서 이루어지고 있는 치료교육활동의 실태와 요구를 파악하고 보다 적합한 치료교육을 위한 개선방안을 찾고자 한 정책연구이다. 이를 위하여 본 연구에서는 치료교육의 개념, 역사, 외국 사례 등에 관한 문헌을 탐색하였으며, 설문조사를 통하여 치료교육의 실태와 요구를 분석하였고, 이를 바탕으로 한 치료교육의 개선방안을 도출하였다. 본 연구의 설문조사를 위하여 전국의 142개 특수학교와 182개 지역교육청을 대표하는 1,078명의 교사들로 조사단을 구성하여 설문지를 배부하였다. 그 결과 전국의 16개 시·도교육청에 소속된 142개 특수학교 중 140개 특수학교에서 설문응답에 참여하였으며, 182개 모든 지역교육청에 소속된 교사들이 설문응답에 참여하여, 총 1,046부의 설문지가 수합되었음을 밝힌다. 이 조사를 통하여 치료교육 담당인력의 양적 부족, 치료교육의 내용과 형식에 대한 합의 부족으로 인한 교육실제 상의 혼란이 현 특수학교 치료교육의 대표적인 문제로 제기되었으며, 특수아동 요구의 다양성과 치료교육의 효과성을 동시에 충족하기 위한 치료교육 담당교원의 자격제도 및 배치방법의 해결과 치료교육을 실시하기 위한 공간 확보의 문제가 일반학교 특수학급에서의 치료교육을 위한 주된 요구로 제기되었다. 이와 같은 설문조사의 결과를 바탕으로, 다섯 명의 연구진 중 대학에 재직 중인 세 명의 공동연구자들이 서로 다른 각도에서 치료교육의 문제점과 개선방안을 조명하였다. 따라서 세 가지의 큰 학문적 흐름을 가지고 방안이 주창되었으나, 그 방안 속에서 논해진 구체적인 하나하나의 제안들은 각자의 학문적 입장에서만이 아니라 다양한 현실적 상황을 고려하여 심사숙고된 결과임을 밝힌다. 마지막으로 본 연구의 맺는 말에서는, 일단은 특수교육진흥법과 특수학교 교육과정에 근거하여 교육서비스로서 행해지고 있는 치료교육 시스템의 견고한 틀 안에서의 개선을 논하는 것이 최선일 것으로 보고, 세 가지 큰 흐름의 방안들에서 최소한의 공통되는 제안들을 다음과 같이 종합하였다. 우선 첫째, 치료교육 교사 양성에 있어서의 전공 분야 세분화가 필요하다. 둘째, 기존의 치료교육 교사들이 세부 전공 영역의 전문성을 가질 수 있도록 하는 보완적 교육이 행해져야 한다. 셋째, 특수교사로서의 치료교육교사에 의한 치료교육 제공을 교실교육과 순회교육을 기본 원칙으로 하되, 순회가 불가능한 지역이나 일반학교 일반학급, 일반 유치원 내의 특수아동들을 위하여 필요한 경우에는 교육기관 외의 기관에 소속되어 있는 치료사 인력들을 활용할 수 있는 권역별 인력풀 제도를 마련한다. 넷째, 특수교육과 치료교육의 관계 및 내용적 정체성 확립을 위한 근본적인 재조명이 필요하다. The purpose of the present study is to investigate the current practice of the therapeutic education in Korea. The survey data were collected and analyzed from 332 therapeutic educators, 367 special school teachers, and 347 special classroom teachers. Results of the present study were summarized and discussed by three of the researchers based on their academic standpoints. The problems of current therapeutic education analyzed by this study are the lack of therapeutic educators, confused understanding of the contents and methods of therapeutic education, low professionalism of the therapeutic educators, and the lack of space to carry out therapeutic education in general schools, etc. The common suggestions from the three researchers were summarized as follows: first, the courses of universities for training therapeutic teachers have to be more specialized. Second, some kind of training programs for the existing therapeutic teachers are needed to get them more specialized certificates. Third, the community human resource pool including not only therapeutic teachers but also professional therapists should be available. Fourth, the identity of the therapeutic education in special education delivery system needs to be reestablished academically and practically.
