저자들은 신부전이 동반된 당뇨병 환자에서 발생된 부비동형 모균증에 대하여 수술과 함께 liposomal amphotericin B 및 GM-CSF의 복합치료를 하여 성공적으로 치료한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Mucormycosis (zygomycosis) primarily affects diabetic or immunocompromised patients and typically progresses rapidly, necessitating surgical excision and antifungal therapy with amphotericin B. Large doses of amphotericin B are needed for cure, but it has the risk of causing significant renal toxicity. The recent development of liposomal amphotericin B allows antifungal therapy to be administered with potentially improved efficacy and reduced nephrotoxicity. We have experienced a case of paranasal mucormycosis successfully treated with surgery, liposomal amphotericin B and GM-CSF. A 59-year-old male suffering from diabetes mellitus for 6 years was admitted with pain at left maxillary area. He was diagnosed as mucormycosis after cytologic exam on the necrotic nasal mucosa, which showed typical hyphae. He have had diabetic nephropathy with macroproteinuria and had rapidly rising serum creatinine levels with the amphotericin B treatment: creatinine levels reverted to basal level with the use of liposomal amphotericin B. Despite surgical excision and continued antifungal therapy, his infection was not effectively controlled. Therefore, GM-CSF was administered additionally to improve phagocytic activity of leukocytes. He was finally cured after receiving a combination of aggressive surgery, liposomal amphotericin B and GM-CSF. To our knowledge, this is the first detailed clinical description of the treatment of mucormycosis with liposomal amphotericin B in Korea.

( Dong Hyuk Shin ),( Sang Kuk Han ),( Pil Cho Choi ),( Seong Woo Lim ),( Kyung Mook Kim ),( Dong Hyun Sinn ) 대한소화기기능성질환·운동학회 2010 Gut and Liver Vol.4 No.2

Background/Aims: Vaccination against hepatitis A virus (HAV) is recommended for patients with chronic hepatitis B (CHB), since they are potentially at an increased risk of HAV-related morbidity and mortality. However, little is known about the adherence to these recommendations in the community. This study evaluated the current vaccination status and immunity against HAV among Korean military soldiers with CHB. Methods: We performed a prospective study of Korean military soldiers from August 2008 to January 2009. We enrolled 96 soldiers with CHB on a consecutive basis. We assessed their vaccination history and the presence of anti-HAV immunoglobulin G (IgG). Results: The HAV vaccination rate of the soldiers enrolled in our study was 2% (2 of the 96 soldiers). The seroprevalence rates of anti-HAV IgG among military soldiers without a vaccination history were 0%, 50%, and 100% for those aged 19-29 years (n=71), 30-39 years (n=8), and 40 years or older (n=15), respectively (p<0.001). Conclusions: The HAV vaccination rate is very low among military soldiers. Public health efforts aimed at raising awareness about HAV vaccination in patients with CHB should be strongly encouraged.

This study was conducted with the aim of evaluating the antibiotic effects of leaves, stems, and roots in yacon (Smallanthus sonchifolius). Antibacterial activity of leaf extract by disk diffusion method with Bacillus subtilis and Escherichia coli respectively showed 13.3 and 13.75mm diameters of clear zone. There was no significant difference between the stems and leaves. The minimum inhibitory concentration of leaves’ heating and agitation extraction showed a restrain of strain at 1mg/ml, but the stems and root extract did not appear. Yacon is a functional antibacterial material, and methanol extraction is more effective than water. This research was to investigate the growth stage of collection has the most effective antibacterial effects. It has collected yacon's leaves from June to October, which is an appropriate time for collection right before reaping. Yacon leaf has antibacterial effects on Bacillus subtilis, Escherichia coli, Enterococcus faecium, and Salmonella enteritifis. There were no significant differences by the growth stage of collection. Leaves collected in July are high in phenol which helps in sulfating activity works well considering the high scavenging capability of DPPH. Leaves collected in September are high in total flavonoid.

The synthesis of phenoxyalkanoic acid derivatives and their anti-inflammatory and analgesic activities are described. Analysis of structure-activity relationships shows that in trichlorophenoxy derivatives anti-edematous potency is associated with the presence of 1-thiopropyl moiety and 2 or 40aminopyridyl moiety at $R^{l}$ position contributes to the analgesic activity.

국부적 영역에서의 특징 공간 속성을 이용한 다중 인식기 선택

본 논문은 시험 표본 주위의 영역에 대한 속성을 이용한 다중 인식기 선택 방법을 제안한다. 기존의 DCS-LA 동적 인식기 선택 방법은 시험 표본 주위의 학습표본들을 사용해서 각 인식기의 국부적정확성을 계산하여 인식기를 동적으로 선택하기 때문에 인식 시간이 오래 걸린다. 본 논문에서는 특징공간에서 국부적인 속성을 계산해서 그 속성값에 적합한 인식기를 미리 선정해서 저장해 놓은 후 시험 표본이 들어오면 그 주변의 속성값에 따라 저장된 인식기에서 선택을 하기 때문에 인식시간을 줄일 수 있다. 국부적인 속성으로는 표본 주위의 작은 영역에 대한 엔트로피와 밀도를 계산하여 사용하였으며 이들을 특징공간속성(Feature Space Attribute)라고 하였다. 이들 두 속성으로 이루어지는 속성 공간을 규칙적인 사각형 셀로 나누어, 학습과정에서 각각의 학습표본에 대해 계산된 속성값이 어떤 셀에 속하는지를 구한다. 또한 각 셀에 속하는 학습표본들에 대해 각 인식기의 국부적 정확도를 구하여 셀에 저장한다. 시험 과정에서 시험표본에 대해 속성값 계산을 통해 그 표본이 속하는 셀을 구한 후 그 셀에서 국부적 정확도가 가장 높은 인식기로 인식한다. Elena 데이타베이스를 사용해서 기존의 방법과 제안된 방법을 비교하였다. 제안된 방법은 기존의 DCS-LA와 거의 같은 인식률을 나타내지만 인식속도는 약 4배 가까이 빨라짐을 실험을 통해 확인할 수 있었다. This paper presents a method for classifier selection that uses distribution information of the training samples in a small region surrounding a sample. The conventional DCS-LA(Dynamic Classifier Selection - Local Accuracy) selects a classifier dynamically by comparing the local accuracy of each classifier at the test time, which inevitably requires long classification time. On the other hand, in the proposed approach, the best classifier in a local region is stored in the FSA(Feature Space Attribute) table during the training time, and the test is done by just referring to the table. Therefore, this approach enables fast classification because classification is not needed during test. Two feature space attributes are used : entropy and density of k training samples around each sample. Each sample in the feature space is mapped into a point in the attribute space made by two attributes. The attribute space is divided into regular rectangular cells in which the local accuracy of each classifier is appended. The cells with associated local accuracy comprise the FSA table. During test, when a test sample is applied, the cell to which the test sample belongs is determined first by calculating the two attributes, and then, the most accurate classifier is chosen from the FSA table. To show the effectiveness of the proposed algorithm, it is compared with the conventional DCS-LA using the Elena database. The experiments show that the accuracy of the proposed algorithm is almost same as DCS-LA, but the classification time is about four times faster than that.
