        Identification of differentially expressed proteins in the bacterial biofilm

        강치덕,최점일,Kang, Chi-Dug,Choi, Jeam-Il The Korean Academy of Periodontoloy 2005 Journal of Periodontal & Implant Science Vol.35 No.2

        본 연구는 치주낭에 biofilm형태로 부착되어 질환을 유발시키고 항생제 빚 항균제에 저항을 일으키는 세균 독성요소를 규명하기 위해 시행된 기초연구이다. 치주질환의 주 병원균의 하나인 Porphyromonas gingivalis 381 biofilm의 세포외막에 특이하게 발현되는 단백질을 규명하기 위한 기초적인 자료를 얻기 위해 시행하였다. Porphyromonas gingivalis 381을 통상적인 세균 배양용 broth를 사용하여 혐기성 세균 배양기로 24시간 배양한 것을 대조군으로 하고, tissue culture plate를 이용하여 혐기성 배양조건 하에서24시간동안 biofilm을 형성하여 실험군으로 설정하였다. 세균을 수획하여 세포외막을 분리하고 isotonic isoelectric focusing을 시행한 결과 주로 약 20-30 kilodaltons에 해당하는 수종의 세균세포막 단백질이biofilm으로 배양한 세균에서 더 상승적으로 발현됨이 관찰되었고, 상이한 수종의 단백질도 planktonic culture broth로 배양한 세균에서 다 상승적으로 발현됨을 관찰할 수 있었다. 이것은 세균의 배양조건과 환경에 따라 그 외막 단백질이 서로 다르게 발현됨을 입증하는 기초적인 자료로서 향후 단백질의 동정과 성격을 규명하는 근간 실험으로 추진할 계획이다.

        관절염환자(關節炎患者)의 특성(特性)에 대한 조사(調査) 연구(硏究)

        In order that, investigating the feature of patients suffering arthritis, analysing its contents, and grasping a Primary factor affecting it, I might offerbasic datas which could help to plan and perform healthy affairs to thake precautions beforehand, I have investigated, analysed, and studied a total of 320 patients suffering arthritis, who have received physiotherapy in hospital located in Teaegu area for five months, from November 1 1995 to March 30 1996, of which summary and conclusion is this. 1. The general feature of patients in investigative objects In the distribution of the distinction of sex, men accounted for 26.9% and women, for 73.1%, and, in the fistribution of age, 60-year-old or more, most for 27.2% and from 20 to 29 years old, least for 14.0%. In the distinction of a vocation, housewives most accounted for 34.7% and students(jobless men), least for 19.3%. In the distinction of a matrimonial state, married persons most accounted for 76.7% and people living alone(divorce, separation by death, separation), least for 11.4%. In the distinction of an economic state, the middle classes most accounted for 73.5% and the upper classes, least for 2.9%. In the distinction of their academic careers, graduates of a primary school most accounted for 26.9% and graduates of university, for 14.1%, of which patients, having the ability to decode the national language, reached to 11.3%. In the distinction of the house form, people living in independent houses most accounted for 76.4% and residents in apartment(having an elevator), least for 9.4%. 2. In the distribution of the recurring state in the distinction of the feature, the recurring group was more than the group of patients falling that ill at first as 62.2% and in the distinction of the feature of the recurring group, the recurring group turned high in case of men being from 50s to 60s years old or more, people living alone (divorce, separation by death, separation), students (joblessmen), people working in farming, stockbeeding, forestry, fisheries, a simple labour, graduates of a primary school I having the ability to decode the national language, the upper classes, people part two years since they begined to suffer arthritis, people who had members having ever experienced arthritis among families. 3. In the distribution of arthritis on the distinction of bodily pars, a knee articulation most accounted for 50.2% and the articulation of fingers, for 8.8%, wile the simultaneous, several parts (multiple) accounted for 35.1%. In the distinction of the feature, arthritis of a knee turned high in case of men being from 20s to 30s years old, unmarried persons, people having academic careers of university, the middle classes, residents in apartment (having stairs). In the dictnction of a feature the case of several parts (multiple) turned high in case of women being from 50s to 60s years old or more, people living alone (divorce, separation by death, separation), people having the ability to decode th. national language, the graduates of a primary school, the upper classes, residents in apartment (having elevator). 4.
