Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

Column tests in the laboratory were preformed to investigate characteristics of settling process of dredged soil sampled from in-situ. Test results were analyzed by using the existing theories on discrete settling and hindered settling. From column tests of monitoring the interface with time, settling was found to be a linear process with time and the settling rate was increased with initial water content of slurry. The settling rate was also observed to decrease with increasing initial height of slurry. Most of settling process were composed of flocculation, hindered settling and self-weight consolidation. On the Other hands, flocculation of soil during settling was observed and it was found that the size and density of flocculated particles could be analyzed by using the method proposed by Richardson and Zaki.

A biped walking robot is constructed and used to develop algorithms for noble tasks as climbing stairways and kicking a ball. The constructed biped robot system consists of four pat ; a host controller, a mechanical robot body, a CCD camera, and a local controller. An algorithm for climbing stairways is developed and applied to the biped robot. Experimental results show that the robot can climb stairways in a statically stable fashion with the developed algorithm. An algorithm for camera calibration with minimum nonlinear distortion is adopted to acquire three-dimensional distance from image data. The biped robot can kick a ball by using the acquired distance information.

유전성 대사질환에서의 동종조혈모세포이식 : 단일 기관에서의 경험 A single center experience

유건희,김흥렬,이지은,이호영,천정미,성기웅,구홍회,이문향,진동규,김종원,김대원,김형록 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.2

배경: 유전성 대사질환의 치료로서 효소 요법 및 유전자 치료가 제한적인 현실에서 동종 조혈모세포이식이 현재로선 가장 중요한 치료가 될 수 있다. 본 연구에서는 단일 기관에서 유전성 대사질환에 대해 동종 조혈모세포이식을 시행한 경험을 보고하고자 하였다. 방법: 삼성서울병원 유전성 대사질환 조혈모세포이식팀에서는 1999년 12월부터 2001년 3월까지 총 6례의 유전성 대사질환을 대상으로 동종 조혈모세포이식을 시행하였다. 대상 질환은 Hunter 증후군 3례, galactosialidosis 1례, 이염성 백질이영양증 1례, 부신백질이영양증 1례였으며 성별 분포는 남아가 5명, 여아가 1명이었으며 연령 분포는 2년 9개월에서 15년 9개월이었다. 5례는 HLA 일치 혈연간 골수이식이었으며 1례는 HLA 불일치 T 림프구 제거 말초혈액 조혈모세포이식이었다. 전처치는 모두 BuCy를 사용하였으며 이식편대숙주반응의 예방에는 cyclosporine을 사용하였다. 이식된 세포는 유핵세포가 4.81×10^(8)(2.40~7.01×10^(8))/kg이었으며 CD34+ 세포는 3.65×10^(6)(0.88~10.72×10^(6))/kg이었다. 결과: 이식 후 조혈기능의 회복은 모두 조기에 달성되었으며(ANC>500: 정중 9.5일, 범위 9~14일; PLT>50K: 정중 32일, 범위 23~34일) 이식과 관련된 합병증은 Gr I의 aGVHD 3례, 국한성의 cGVHD 1례, 경증의 간정맥 폐쇄성 질환이 1례이었다. 모든 환자에서 직간접적으로 이식 후 효소의 생산이 증가함이 확인되었으며 임상적인 호전을 보인 경우가 4례, 질병 진행이 중단된 경우가 1례, 질병이 진행된 경우가 1례이었다. 질병 진행이 중단되었던 1례는 면역억제제 투여 중 수두 감염에 의한 폐출혈로 사망하였다. 결론: 유전성 대사질환에서 동종 조혈모세포이식이 가장 중요한 치료법으로 사용될 수 있고 중추신경계 증상이 나타나기 전, 가능한 조기에 조혈모세포이식을 시행하는 것이 바람직할 것이며 적극적인 지지 요법이 필요하다. 향후 더 많은 임상 경험이 필요하리라 사료된다. Background: Allogeneic hematopoietic stem cell transplantation (HSCT) may be the most important treatment modality to cure a number of genetic metabolic disorders because of the limitation of enzyme replacement or gene therapy. In this study, we report our single center experience about HSCT in several genetic metabolic disorders. Methods: We performed 6 cases of HSCT for genetic metabolic disorders from December 1999 to March 2001. Patients' diagnoses were Hunter syndrome (3), galactosialidosis (1), metachromatic leukodystrophy (1), and adrenoleukodystrophy (1). Stem cell sources were bone marrow from HLA matched sibling donors in 5 patients and mother's peripheral blood stem cells in one patient who did not have HLA matched donors. Busulfan and cyclophosphamide for conditioning, and cyclosporine for the prevention of graft versus host disease were used in all patients. Transplanted total nucleated cell counts were median 4.81×10^(8)(2.40~7.01×10^(8))/kg , and CD34+ cells 3.65×10^(6)(0.88~10.72×10^(6))/kg. Results: All patients achieved early hematologic recovery (median 9.5 days, range 9~14 days for ANC>500/μL; median 32 days, range 23~34 days for PLT>50,000/μL). Transplant-related complications were 3 cases of grade 1 acute GVHD, a case of limited chronic GVHD, and a case of mild hepatic veno-occlusive disease. Enzyme levels were normalized in 4 patients evaluated and there were indirect evidences of enzyme production in the other 2 patients after HSCT. Four of the 6 patients showed symptomatic improvement, 1 patient (galactosialidosis) experienced disease stabilization without progression before he eventually died due to pulmonary hemorrhage, and the other 1 patient deteriorated progressively even after HSCT. Conclusions: Allogeneic HSCT can be done as the only curative treatment in a number of genetic metabolic disorders. It seems desirable to perform HSCT as early as possible before the onset of central nervous system symptoms. More experience and long term follow up is needed to evaluate the efficacy and to monitor the long term transplant-related complications.

위 MALT 림프종에서 다발성 림프절 전이로 오인된 동시성 림프절 결핵 1예

28세 남자가 내시경적 점막절제술을 통해 저등급 위MALT 림프종으로 진단되었다. 병기설정을 위해 18F-FDG PET 검사를 시행하였고 우측 쇄골상부, 우측상/하부 기관주위, AP window 부위에 강한 섭취가 관찰되어 전이성 림프절로 판단하였다. 그러나, 우측 쇄골상부 림프절에서 시행한 절제생검에서 만성육아종성염증소견이 관찰되었고 조직의 결핵 중합효소연쇄반응에서도 양성 반응을 보였다. 2개월간 항결핵제의 사용 후 시행한 추적 컴퓨터단층촬영 검사에서 림프절 크기의 감소를 보여 최종적으로 위 MALT 림프종에서 광범위 림프절 전이로 오인된 동시성 림프절 결핵으로 진단되었다. A 28-year-old man was diagnosed as gastric MALT lymphoma in diagnostic EMR (endoscopic mucosal resection). He subsequently underwent an 18F-FDG PET. 18F-FDG PET showed intense multifocal uptake in right supraclavicular, right upper and lower paratracheal, and AP window areas that was considered radiologically to represent widespread metastatic lymphadenopathy. Excisional biopsy of a supraclavicular lymph node, however, revealed chronic granulomatous lymphadenitis with a positive reaction of Tb-nested PCR. After antituberculosis treatment for 2 months, a follow-up CT scan showed complete resolution of the lesions. Intense 18F-FDG uptake could be due to an infectious process such as synchronous tuberculous lymphadenitis. Therefore, this could mimic a malignant condition such as lymphoma with extensive lymph node metastasis due to a false-positive finding, which may lead to a misdiagnosis.

The purpose of this investigation was to develop a new carrier using chitin and glucan as the model for Aspergillus oryzae cell wall. In case of the ratio of chitin and glucan(3/1), the activity of the immobilized protease had higher than that of model(chitin/glucan=1/3) and carriers were formed gel. In case of soluble chitin and glucan treated with calcium carbonate, there were a 1.8-fold increase in activity of immobilized protease compared with untreated chitin. The scanning electron microscope image showed that a pore size of this carrier had a homogenized pore size and a smooth surface.

Dong Ea(東夷) Tribe who had been the generative power of the development of the Asian culture was a strong hunting race. They took the leadership in the middle field of China. They were the pioneers of the Dong Ea country who blssomed the culture of the Yellow River and the creator of the Oriental culture. According to the many documentary records, the archeological remains and the views of scholars, the date that Hwan(桓) country was set up Hwan-Im(桓因) was about 6000-7000 B. C. and the date that Bae-Dal(倍達) was set up by Hwan-Woong(桓雄) was 389 B. C. the Dynasty, Go-Cho-Seon(古朝鮮) by Dan-Goon(檀君), the beginning of our country was set up in 2333 B. C. So we have 5000 years of history. After Bal-Hae(渤海) was parished in 928 A. D. the boundary of our historical rang in Kora was limited to the Han Paninsula. As we know the fact that the prosperity and decline of the power of a nation determined by the nation's boundary line, we must try to restore the former boundary line of our country and lengthen the length of our nation's history. Although we now have poor documentary records, we must have positivism of history and the method of positive description of history. So we must re-compile the text book of history of our country with the objective propriety and rational reserarch of historical documents. By discovering and clarifying the origin of our nation. We must have the progressive historical view for the unification of our country and we can soar up our country and must restore our lost continent.
