국내에서 아직 잠복결핵 치료 대상 및 치료 방법에 대한 명확한 지침이 부족한 실정이며 이를 위해서는 잠복감염의 재활성화 혹은 새로운 감염이 어느 정도 결핵 발병의 원인이 되는지에 대한 연구가 선행되어야 한다. 그렇지만 발병의 위험이 높은 군을 선정하여 잠복결핵의 치료 대상으로 정하는 것이 타당할 것이며, 현재는 HIV 감염자, 전염성 결핵환자 가족 중 6세 미만의 아동, 중학생 및 고등학생에서의 집단 발병시 감염된 것으로 판정된 학생 및 종양괴사인자(tumor necrosis factor, TNF) 길항제 사용 예정인 잠복결핵 환자가 잠복결핵의 치료 대상으로 제한되어 있다. 향후에는 잠복결핵 치료 대상자의 확대가 필요할 것으로 생각되며, 치료방법 또한 isoniazid (INH) 단독 요법 이외에 rifampicin (RMP)을 포함하는 단기 요법의 사용도 고려하여야 하겠다. 현재 외국에서 잠복결핵의 치료법으로 권고되고 있는 것은 INH 6~9개월, RMP 4~6개월, INH/RMP 3개월 등이다. 과거부터 잠복결핵의 진단에 사용되어 온투베르쿨린 검사 외에 체외 인터페론감마 검사가 새로이 개발되면서 잠복결핵의 진단이 더 정확해진다면 이에 따라 잠복결핵 치료 방침도 수정될 가능성이 있으므로 새로운 검사법을 이용한 꾸준한 연구가 필요할 것이다.

The purpose of this was to evaluate the level of knowledge about Hepatitis B and AIDS among dental hygiene students at six dental hygiene educational programs in nationwide, compare the findings to those of Song's study. 1703 dental hygiene students surveyed by mail and answered a questionnaire, using the questionnaire used developed by DiClemente el al., on Hepatitis B vaccination, antibody production, experience of unintentional needle stick injuries, experience of surgical operation and blood transfusion, personal risk factors for HBV and HIV, management of HBV and HIV postexposure management et al. The data indicated that dental hygiene students (79.0%) in this study had more HIV vaccination than dental hygiene(74.3%) in Song's study. As for recognition of antibody production after Hepatitis B vaccination, only 34.6% of respondents answered they knew having antibody production and 95% of respondents knew not having antibody production. Over one-half of the respondents (55%) answered they didn't even recognize having antibody production. 52.3 percent of dental hygiene students experienced unintentional needle stick injuries. The findings on the knowledge about Hepatitis B and AIDS were that dental hygienists (76.5 points) received higher mean score than those of dental hygiene students (71.0 points) and that the distribution of right answer rate also showed wider range in dental hygiene students (27.7~97.5%) than those of dental hygienist (41.2~99.5%). There were no statistical differences among dental hygiene education programs. Finding of this study support that the curriculum of dental hygiene program should include instruction on sources and methods of transmission of infectious diseases, risk of virus transmission in the workplace and principles of infection control. Furthermore, infection-control practices should be utilized routinely and their application to dental personnel, management of HBV and HIV postexposure management. Furthermore, for preventing the further spread of infectious diseases (HBV, HIV and AIDS${\cdots}$) caused by bloodborne viruses, imposing an obligation rather than recommendation on Hepatitis B vaccination to all dental personnel and routinely utilizing infection-control guidelines for all dental patients in dental practices (include dental educational programs) should be accomplished by coordination the government agency.

HIV와 유사하게 retro virus의 일종인 Friend virus of Anemia strain (FVA)을 BALB/c mice 에게 감염시 reverse transcriptase 의 활성에 의해 비장의 erythroid progenitor cell 에서 증식되므로서 비장의 비대 및 빈혈을 초래하게 된다. 이를 지표로 하여 reverse transcriptase 억제작용을 지닌 항 virus 약물을 천연성분으로 부터 검색하고자 하였다. 우선, 대조약물로 사용한 기존의 항 AIDS 약물인 zidovudine (AZT) 을 FVA 가 감염된 BAB/c mice 에게 18일간 투여시 (약 100 mg/kg/day, p.o. ) 대조군에 비해 비장의 비대 및 reverse transcriptase 활성이 90% 이상 억제되었으며, 이들의 혈청을 정상 BALB/c mice 에게 재투여시에도 유사한 결과를 나타내어 reverse transcriptase 를 억제하므로서 항 virus 작용을 나타낸다는 것을 입증하였다. 그러나, 혈액중 Hemoglobin등 빈혈의 지수는 대조군과 유사한 수치를 나타내므로서 정상으로 회복되지를 못하였다. 이것은 zidovudine 자체가 지니는 골수억제에 의한 부작용 때문인 것으로 고려된다.

Background : Rifampicin (RFP) is a key component of the antituberculous short-course chemotherapy. Usually the RFP resistant M.tuberculosis is also resistant to isoniazid (INH), so the RFP resistance is the marker of multi-drug resistant (MDR) tuberculosis. But unusual cases of mono-RFP-resistant tuberculosis have been recently reported with increasing frequency, especially associated with HIV infection in western countries. Therefore, we conducted a retrospective study to investigate the frequency, causes, and the clinical characteristics of mono-RFP-resistant tuberculosis in Korea. Methods : Of the bacteriologically confirmed and susceptibility-proven 699 pulmonary tuberculosis patients (921 isolates) who visited Asan Medical Center from January 1990 to August 1997, eighteen patients with INH-susceptible and RFP-resistant tuberculosis were evaluated. Previous history of tuberculosis, antituberculous drug compliances, associated systemic illness, drug susceptibility patterns, and clinical outcomes were analysed. And rpoB gene sequencing was done in 6 clinical isolates of M. tuberculosis. Results : The mean age of 18 patients was $43{\pm}14$ years, and the sex ratio is 12:6 (M : F). Sixteen (89%) patients had previous history of tuberculosis. None had diagnosed gastrointestinal disorders, and 2 HIV tests that were performed came out negative. Susceptibility tests were done repeatedly in eleven patients, and six (55%) were mono-RFP resistant repeatedly while five (45%) evolved to MDR tuberculosis. Eight (44%) patients were cured, six (33%) failed, three (17%) were lost to follow-up, and the other one is now on treatment. rpoB gene sequencing showed 5 mutations, codon 531 TCG to TIG mutation in 4 isolates and 526 CAC to TAC in 1 isolate. Conclusion : The clinical characteristics of mono-RFP resistant tuberculosis were similar to that of MDR tuberculosis in Korea where the HIV infection rate is lower than western countries. But some patients with mono-RFP-resistant tuberculous could be cured by primary drug regimens including RFP, suggesting that mono-RFP-resistant tuberculous is a different entity from MDR tuberculosis.

Cryptococcosis is a subacute or chronic inflammation that's caused by infection from cryptococcus neoformans in the soil or dust that's contaminated by pigeon droppings. Pulmonary cryptococcosis occurs in immunocompromised patients, and particularly in HIV positive patients, but it rarely occurs in immunocompetent individuals. It is most often detected as asymptomatic single or multiple nodules that are found by chest X-ray examination. In these situations, the diagnosis for most cases is made by the histology of the resected lesion. We report here on a case of solitary nodular pulmonary cryptococcosis that occurred in a 32 years old female patient who underwent thyroidectomy for treating her thyroid cancer.

Background : Nontuberculous mycobacteria (NTM) have usually been considered to be contaminants of colonizers when isolated from respiratory specimens in Korea, where there is a high prevalence of tuberculosis and a low rate of HIV infections. Therefore, there has been few studies on the clinical significance of NTM species in immunocompetent patients were investigated. Methods : Thirty-five NTM isolates, for which species identification was requested by the treating physicians during 1999 at the Asan Medical Center, were retrospectively analyzed. They were identified to the species level by mycolic acid analysis using high-performance liquid chromatography. The medical records of the patients with the NTM isolates were reviewed to identify those patients who met the American Thoracic Society (ATS)'s criteria for mycobacterial pulmonary infection. Their antimicrobial susceptibility data were compared with the clinical outcomes. Results : The NTM were identified as M. intracellulare (6 isolates), M. avium (5), M. abscessus (5), M. gordonae (5), M. terrae complex (4), M. szulgai (2), M. kansasii (2), M. fortuitum (2), M. peregrinum (1), M. mucogenicum (1), M. celatum (1), and M. chelonae (1). All 35 patients showed clinical symptoms and signs of chronic lung disease, but none had a HIV infections; 16 (45.7%) patients were found to be compatible with a NTM pulmonary infection according to the ATS criteria, 5 and 4 cases were affected with M. intracellulare and M. abscessus, respectively; 8 patients had a history of pulmonary tuberculosis. 13 patients received antimycobacterial therapy for an average of 21 months and 9 patients were treated with second-line drugs. Only 4 patients had improved radiologically. Conclusion : A NTM should be considered a potential pathogen of pulmonary infections in immunocompetent patients with chronic pulmonary diseases. Most NTM infections were left untreated for a prolonged period and showed a poor outcome as a result, M. intracellulare and M. abscessus were the two most frequent causes of NTM pulmonary infections in this study. Species identification and antimycobacterial susceptibility tests based on the species are needed for the optimum management of a NTM pulmonary infection in patients.
