목적 : H. influenzae는 성인에서 흔히 호흡기 감염을 일으키는 균주로, 최근 ampicillin 내성 β-lactamase 생성 균주들이 지속적인 증가를 보이고 있어, 이에 국내 성인에서 H. influenzae에 의한 감염의 임상양상과 분리된 균주들의 미생물학적 특성을 조사하고자 하였다. 방법 : 1998년 3월부터 1999년 9월까지 고려대 구로병원에 내원한 환자중에서 H. influenzae가 분리된 68명을 대상으로 임상양상을 조사하고 항균제 감수성 검사를 시행하였다. 분리된 33주에 대해서 혈청형, 생물형, 세포외막 단백분석을 시행하였고, β-lactamase 생성여부에 따른 감염 환자군간 임상상 및 예후의 차이를 비교하였다. 결과 : 환자의 평균연령은 68세였고, 지역사회 획득감염이 전체의 85%를 차지하였다. 폐렴과 기관지염과 같은 하기도 감염이 전체환자의 75%를 차지하였고 분리 검체 역시 객담이 84%로 가장 많았다. 환자의 71%가 기저질환을 가지고 있었으며, 그 중에 만성 폐쇄성 폐질환, 심혈관 질환, 악성종양, 당뇨병이 대부분이었다. 혈청형으로는 nontypeable 형이 68%로 가장 많았고 b형은 한 예도 없었다. β-lactamase 생성율은 63.2%였고, β-lactamase 양성균주의 항균제 내성율이 음성균주에 비하여 높았으나 β-lactamase 생성 여부에 관계없이 cefotaxime, azithromycin, ciprofloxacin에 대하여 100%의 감수성을 나타내었고 cefaclor, cefuroxime에 대해서는 10% 이하의 낮은 내성율을 보여 이들 항균제들이 치료에 효과적일 것으로 사료된다. 세포외막 단백분석에서는 C형과 D형이 전체의 64%로 가장 많았으며, 혈청형과의 유의한 연관성은 보이지 않았다. 결론 : 성인에서 H. influenzae는 주로 만성 기저질환자에서 급성 호흡기감염 또는 만성 폐쇄성 폐질환의 급성 악화를 유발한다. 기존의 보고에 비해 β-lactamase 양성율이 증가하였고, 이에 따른 항균제 내성율도 증가하여 항균제의 선택에 유의하여야 할 것으로 생각된다. 세포외막 단백분석상 특정한 유형의 균주에 의해 감염이 집중적으로 발생하고 있어 향후 역학 조사의 도구로 이용할 수 있겠다. Purpose : H. influenzae is one of the common causative microorganisms of respiratory tract infections in adults. Recently. β-lactamase producing, ampicillin-resistant H. infiuenzae has become worldwide problem as well as in Korea. We studied to investigate the clinical features and microbiologic characteristics of H. infiuenzae infections in adults. Materials & Methods : From March 1998 to September 1999, 68 patients were enrolled in this study. Clinical features of H. infiuenzae infections were investigated, 68 isolates were subjected to the β-lactamase test, and 33 isolates were used for serotyping. biotyping, antibiotic susceptibility and outer membrane protein (OMP) analysis. Results : Mean age of study patients was 68 years-old and the acquisition rate in community was 85%. Pneumonia and bronchitis were the most common type of infection such as 80%, sputum was the most common clinical specimen for H. mQuenzae isolation. 70% of patients had chronic underlying diseases. Non-typeable strains were 68% and β-lactamase producing rate was 63%. There was no difference in the clinical features and prognosis of H. influenzae infection between the β-lactamase positivie and -negative groups. The susceptibility of cefotaxime, azithromycin, and ciprofloxacin was 100% and that of cefaclor, cefuroxime was under 10% in spite of β-lactamase positivity. In OMP analysis, C and D types were dominant (64%). Conclusion : H. influenzae caused acute respiratory infections in adults with chronic underlying disorders. This study shows higher β-lactamase producing rate and antibiotic-resistance rate than that were reported previously. OMP analysis shows that two major types of strains cause clinical infections intensively.

Dehydrocoupling of Bis(1-sila-3-butyl)benzene and 2-Phenyl-1,3-disilapropane to Polymers Using Zirconocene Combination Catalysts

Jun Lee, Jong-Hyun Kim, Soo-Yong Mo, Hee-Gweon Woo1, Do-Heyoung Kim, Jin Jun 조선대학교 기초과학연구원 2011 조선자연과학논문집 Vol.4 No.3

The catalytic dehydrocoupling of bis(1-sila-3-butyl)benzene 1 and 2-phenyl-1,3-disilapropane 2 by Cp2ZrCl2/Red-Al and Cp2ZrCl2/n-BuLi was reported to compare their catalytic efficiency. The dehydrocoupling of monomeric silanes 1 with the Cp2ZrC12/Red-Al and Cp2ZrCl2/n-BuLi combination catalysts produced two phases of polymers: one is a highly crosslinked insoluble solid, and the other is noncross-linked or slightly cross-linked soluble oil and could be a precursor for the solid polymer. The dehydrocoupling of 2 with the Cp2ZrCl2/n-BuLi combination catalyst similarly produced two phases of polymers. By contrast, the catalytic reaction of 2 with the Cp2ZrCl2/Red-Al combination catalyst produced a soluble polymer via redistribution/dehydrocoupling process.

Perceptions and concerns of parents about elementary school lunch service were investigated by questionnaires in March, 1998. Five hundred and ten parents were selected randomly from schools in the city area, the rural area or the islands in Incheon Metropolitan city. 95% of parents preferred the school lunch service because nutritious food was available to the children regardless of family income or mother's occupation. Meal cost per capita was in the range of 1,000 and 1,200 won, which satisfied most parents (74%). Moreover, many parents (68.8%) were willing to pay extra money to support the school lunch program and they actually had such experiences (82.4%). More than 90% of the respondents wanted to be adviced about the menu. Subjects chose nutrition and sanitation (25%), taste (18%), and meal size (16%) as aspects of improvement in school lunches. Parents wanted to participate in serving foods, cooking, and washing dishes once (23%) or twice (31%) a year and they considered this as a good opportunity to join the school activities. 98% of parents showed very positive responses to the nutritional education provided by the school dietitian.

Weight reducing methods were surveyed by questionnares in March through May, 1998 with 641 women living in Inchon to provide the information for the education of proper weight control. Methods that they have used for weight-reduction were exercise (33.1%), diet therapy(29.6%), sauna(7.3%), ingestion of special food(4.8%), administration of drugs(4.0%) and herb-medicines. The respondents considered exercise (38.4%) and diet therapy (31.5%) as the most effective methods in reducing weight and the response was different with ages at p<0.01. They have practiced the diet therapy by reducing the amount of food(27.7%, skipping one or two meals a day (20.8%), avoiding high calorie snacks(8.06) and regulating food items in a meal(3.8%). Exercises which they have done were walking(48.0%), aerobics (2.390, swimming (23%) and using the health instruments (6,7%). Their choices in kinds of exercises were significantly de-pendent upon ages, marriage and their occupation(p<0.01). Acupuncture(38.0%) was the most frequently used oriental medicine therapy and original drugs(32.2%) and moxibustion(22.0%) were also used. The women have taken drugs was 9.5%. Among them cream-typed cosmetics(41%), weight reducing drugs (30%), diuretics(18%). and smoking(7%) were used. Fifty respondents out of 641 had experiences to have special food therapy such as grape, apples and vinegar(42%) and enzymes(18%) for some period of time.

Objectives : This study was designed to evaluate relation between 6 weeks pharmacotherapy and the alteration of autonomic nervous system in patient with panic disorder. Methods : The subjects were patients (n=44) who met DSM-IV criteha for panic disorder with or without agoraphobia. They were measured Anxiety Disorder Inventory Schedule-Panic attack & agoraphobia (ADIS-P & A), Clinical Global Impression (CGI) Hamilton Rating Scale for depression (HAM-D), Panic Disorder Severity Scale (PDSS) and heart rate Vahability (HRV) before and after 6 weeks pharmacotherapy. We prescribed paroxetine primahly and benzodiazepine (clonazepam, alprazolam) in case needed. For analysis, we performed paired sample t-test, partial correlation, stepwise multiple regression. Results : After 6 weeks pharmacotherapy, a assessed clinical inventories significant improved. In HRV, patients showed stabilized sympathetic activity (LF, Normalized LF, 1og_LF), increased parasympathetic activity (Normalized HF). There were significant correlation between symptom improvement with parasympathetic components and symptom aggravation with sympathetic components. Multiple regression analysis showed that Normalized HF and TP were best explanatory variables of symptom improvement. Conclusion : This study suggests that 6 weeks pharmacotherapy is related to the alteration of autonomic nervous system and clinical improvement.

최근 외국으로의 여행이 빈번해지면서 유입 감염되는 경우가 많아지고 있는 추세이며 임상 증세가 말라리아와 유사하여 다소 진단이 어려울 수가 있어 한번쯤 바베시아증을 생각하는 것이 바람직하겠다. 저자들은 아프리카에 다녀온 뒤 나타난 바베시아증을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Babesiosis is a tick-borne, malaria-like illness caused by Babesia species that infect erythrocytes of mammals incidentally. The family Babesiidae is characterized by consisting of nonpigmented intraerythrocytic parasites that reproduce within erythocytes by asynchronous, asexual budding into two or four daughter cells (tetrad). We experienced a case of human babesiosis presenting fever and chills. The patient was a 49-year old man, who had been in Africa (Ethiopia, Uganda). Three weeks before admission intermittent spiking fever had developed, which had been accompanied by severe chills. The peripheral blood smear (Giemsa-stain) revealed characteristic forms of a intracellular quadraple parasite compatible with Babesia. The patient was improved significantly by the treatment with quinine and clindamycin for a week.

Food habit, eating-out pattern, smoking and drinking habits of 814 elderly (aged over 60) living in Incheon were surveyed by questionnaire. The ratio of the elderly who have balanced meals at moderate amount was slightly higher in urban area. Urban elderly tended to have mild foods, while rural elderly preferred hot and salty foods. Score for food habit was higher in urban elderly and there was no difference between male and female elderly. Most urban elderly had their meal at the public facilities for elderly, while most rural elderly used general restaurant and public room for elderly. Korean foods were the most favorite menu when ate out. Ration of elderly who have difficulites in chewing was 21.2 and 39.6% for urban and rural elderly, respectively. Many elderly, especially more than 70% of female elderly, prepared the meals for themselves. Rural elderly smoked and drank more than urban elderly and male elderly did more than female elderly.
