  • 우리 사회가 중국으로부터 오염물질 이동을 주목하기 시작한 것은 국지 오염 중심의 아황산가스, 먼지 등 1차 오염이 어느 정도 해결된 1990년대 초반 이후이다. 1992년 환경부 선도기술개발사업으로 산성비 감시 및 예측기술개발이 시작되고 1995년부터 국립환경연구원 주도로 배경농도 지역에서 미세입자 측정이 진행되면서 국내의 장거리 이동대기오염물질 연구는 점차 자리를 잡게 되었다. (중략)

  • 안철수연구소(www.ahnlab.com)의 발표에 따르면 2000년 상반기에 국내에서 발견된 신종 바이러스가 346종에 달한다고 발표했다. 이는 99년 상반기(127종)대비 172% 증가한 수치로, 1일 2종 꼴로 신종 바이러스가 제작된 셈이다. 종류별로는 매크로바이러스 65.3%(226종), 트로이목마 23.7%(82종)가 주종을 이루었고, 러브레터를 비롯한 스크립트 바이러스가 급증해 12종(3.5%)에 달한다는 것이 특징적이다. 출처별로는 외산이 83.2%(288종), 국산(16.8%, 58종)보다 비중이 높게 나타났다.

  • Background : Mycobacterium abscessus is the most common respiratory pathogen in rapidly growing mycobacteria and is resistant to all of the first-line antituberculosis drugs. This report describes the clinical and radiographic characteristics in patients with pulmonary disease caused by M. abscessus. Materials and Methods : Twelve patients with pulmonary disease caused by M. abscessus who fulfilled the 1997 American Thoracic Society diagnostic criteria for a nontuberculous mycobacterial pulmonary infection were observed over a five-and-a-half year period. The clinical characteristics and chest radiographic findings were analyzed, retrospectively. Results : The patients were predominantly female(11/12, 92%) and nonsmokers(12/12, 100%). Coughing (10/12, 83%), sputum(10/12, 83%) and hemoptysis(10/12, 83%) were the common symptoms and they had prolonged periods from the onset of symptoms to the diagnosis of their disease(median 6.5 years). Eleven (92%) patients had a previous history of being treated for pulmonary tuberculosis. The sputum specimens were acid-fast bacilli smear-positive in all patients. All patients were administered antituberculosis drugs. Six (50%) patients were treated with second-line antituberculosis drugs on account of persistent smear-positive sputum specimens. The chest radiographs showed that reticulonodular opacities(11/12, 92%) were the most common pattern of abnormality, followed by cavitary lesions(5/12, 42%). The computed tomography findings suggested bronchiolitis from the centrilobular nodules with a tree-in-bud appearances(9/10, 90%) and bronchiectasis (9/10, 90%) were the most common, followed by well-defined nodules smaller than 10-mm in diameter(7/10, 70%). Conclusions : M. abscessus pulmonary disease should be recognized as a cause of chronic mycobacterial lung disease, and respiratory isolates should be assessed carefully.

  • Purpose : Kabuki syndrome is a multiple congenital malformation syndrome with mental retardation. It was named after its characteristic appearance, a face resembling that of an actor in a Kabuki play. To date, six Korean cases of Kabuki syndrome have ever been reported. Here, we present the phenotypic and genetic characteristics of six patients with Kabuki syndrome. Materials and Methods : Between 2003 and 2009, six Korean girls have been diagnosed and followed up as Kabuki syndrome at Center for Genetic Diseases of Ajou University Hospital. Their clinical and laboratory data were collected and analyzed by the retrospective review of medical records. Results : All six patients showed the characteristic facial dysmorphism and developmental delay. Persistent fingertip pads were also found in all patients. Most patients showed postnatal growth retardation (83.3%) and hypotonia (83.3%). Opthalmologic problems were common, particularly for strabismus (83.3%). Congenital heart defects were present in three patients (50%). Skeletal abnormalities including 5th finger shortening (83.3%), clinodactyly (50%), joint hypermobility (50%) and hip dislocation (16.7%) were also observed. There was no patient who had positive family history for Kabuki syndrome. Cytogenetic and molecular cytogenetic analyses including karyotyping and array CGH could not reveal any underlying genetic cause of Kabuki syndrome. Conclusion : Korean patients with Kabuki syndrome showed a broad spectrum of clinical features affecting multiple organ systems. Although clinical manifestations of Kabuki syndrome have been well established, our results failed to detect recurrent chromosome aberrations which could cause Kabuki syndrome. Its natural history and genetic background remains to be further studied for providing appropriate management and genetic counseling.

  • 중국에서는 향후 2년 내에 많은 신규 원자력발전소가 가동을 시작하여 현재 원자력 발전량의 2배를 기록할 것이다. 중국의 신규 원자력발전소 건설 계획이 세계 어느 국가보다도 대규모로 유지되고 있지만, 원자력 발전 용량의 증가는 2020년대에 점차 둔화될 것으로 예측된다.
