구동환,하상우,조수현,박기문,김동운,강국희 성균관대학교 생명과학자원연구소 1997 生命資源科學硏究 Vol.4 No.1

The objectives of this study were to investigate the optimal condition for growth and highly concenterated culture of Bifidobacterium longum (Bif longum). The effects of additives were compared with titratable acidity and viable cell counts, and 10% reconstituted skim milk (no additive) was used as a control. Correlation coefficient for the growth of Bif. longun between CO_2 anaerobic jar method and overalaid medium method was R=0.99. When 1% Bif. longurn was inoculated on 12%, 14%, and 16% reconstituted skim-milk, viable cell counts were 8.60, 8.89, and 8.93 Log CFU/ml, respectively. When Lactose, Glucose, Glucosamine, Fructose, Peptone, N-acethyl-D-glucosamine, D-galactose, and liver extract were added to 16% reconstituted skim-milk, the viable cell counts were 8.61, 9.05, 9.15, 9.24, 8.82, 9.75, 9.17, and 9.64 Log CFU/ml, respectively. Therefore, D-galactose, liver extract, and N-acethyl-D-glucosamine were selected as final additives. When Bif longum was inoculated on Fermentor-I (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% D-galactose and 0.5% liver extract), Fermentor-II (16% reconstituted skim milk containing 0.190% yeast extract, 0.590% N-acethyl-D-glucosamine and 0.5% liver extract), Batch culture-I (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% D-galactose and 0.5% liver extract), and Batch culture-II (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% N-acethyl-D-glucosamine and 0.5% liver extract), viable cell counts were 10.46, 9.37, 9.03, and 8.83 Log CFU/ml, respectively. Although liver extract was the important additive for the highly concentrated culture of Bif. longum in this study, it caused serious off-flavor when liver extract-1 (contained cell mass) was added to Fermentor culture. However, flavor was improved when liver extract-2 which was removed cell mass, was used instead of liver extract-1. Addition of 2% liver extract-II and 1% D-galactose had the similar effect with addition of 0.5% Liver extract-I and 0.5% D-galactose on the growth of Bif. longum.

The mesenteric infarction, as a abdominal disease which show acute abdominal pain and almost need to emergency operation, has very high mortality. This mesenteric infarction has been reported very rarely. Also specific clinical manifestations are not clear, therefore initial diagnosis can be missed easily so that patients usually miss their opportunities for adequate treatment. Especially CAPD patients have high mortality because of their rareness and having similar symptoms like CAPD peritonitis. The authors report that the mesenteric infarction was miss-diagnosed to the CAF'D peritonitis with unspecific symptoms.

초소형 전기장치에 의한 미세 전류가 치아이동에 미치는 효과

김동환,박영국,강승구 대한치과교정학회 2008 대한치과교정학회지 Vol.38 No.5

교정치료 본질인 치아이동을 보다 효과적으로 하기 위한 기계적 힘외의 다른 자극원으로서 전기적 자극에 대한 효용성이 부각되고 있다. 본 연구는 임상에서 초소형 전기장치에 의한 전기 자극이 교정적 치아이동에 미치는 효과를 실증하기 위해 시행되었다. 교정용 미니 스크류를 식립한 성인 여성 교정 환자 7명의 상악 견치 후방 견인 시 실험측에 150 gm의 기계적 교정력 외에 20μA의 직류 전류를 공급하는 초소형 전기 장치를 고안, 제작, 장착하여 견치의 근원심에 1일 5시간씩 4주간 전류 자극을 흘리고, 대조측에는 기계적 자극만을 가한 후, 매 주간 치아 이동량을 측정하여 치아이동에 있어서 전기자극의 효과를 검증하였다. 실험기간 동안 치아이동률에 있어서 실험군에서 대조군에 비해 1, 2째주에서 33%, 3, 4째주에서 21.4% 증가된 치아이동을 보였다. 실험군의 평균 치아 이동량은 1, 2째주가 3, 4째주에 비하여 컸으며, 그 차이는 각각 47%, 24% 증가된 치아 이동량을 보였다. 실험을 통하여 미세 전류가 적용되어 치아이동을 촉진할 수 있다는 것이 임상적으로 실증되었다. 생물학적으로 최적의 치아이동을 계획하여 치료계획을 단축시킬 수 있는 방법은 기계적 교정력과 전기자극을 동시에 가하는 것이라고 제안한다. Objective: The purpose of this study was to determine whether an exogenous electric current to the alveolar bone surrounding a tooth being orthodontically treated can enhance tooth movement in human and to verify the effect of electric currents on tooth movement in a clinical aspect. Methods: This study was performed on 7 female orthodontic patients. The electric appliance was set in the maxilla to provide a direct electric current of 20μA. The maxillary canine on one side was assigned as the experimental side, and the other as control. The experimental canine was provided with orthodontic force and electric current. The control side was given orthodontic force only. Electrical current was applied to experimental canines for 5 hours a day. The amount of canine movement was measured with an electronic caliper every week. Results: The amount of orthodontic tooth movement in the experimental side during 4 weeks was greater by 30% compared to that of the control side. The amount of increase in tooth movement in the experimental side was statistically significant. The amount of tooth movement in the experimental side during the first two weeks was greater than that in the following two weeks. The amount of weekly tooth movement in the control side was decreased gradually. Conclusions: These results suggested that the exogenous electric current from the miniature electric device might accelerate orthodontic tooth movement by one third and have the potential to reduce orthodontic treatment duration.

연구목적 : 강박증의 동반인격장애에 관한 연구들은 기존의 개념과 달리 강박성 인격장애와 강박증 간에는 특이적인 관계가 없으며, 강박증 환자들은 다양한 인격장애를 동반한다는 결과를 보여주었다. 그러나 이러한 연구들은 동반 인격장애에 관한 기술적인 분석에 그쳤고, 강박증 환자군의 임상 증상과 동반 인격장애 양상간의 연관성에 관한 분석을 시행하지 않았다. 본 연구의 목적은 강박증 환자군에서의 동반 인격장애를 평가하고 강박증 환자의 다양한 증상과 동반 인격특성 간의 연관성에 대해 연구하는 것이다. 방 법 : DSM-IV의 강박증의 진단기준을 만족하는 59명의 환자군과 32명의 정상대조군을 대상으로 인격장애 질문지를 적용한 후 4∼6점의 절단점을 기준으로 인격장애의 진단이 내려졌다. 먼저 환자군과 정상대조군 간의 특정 인격장애 빈도의 차이를 알아보기 위하여 Fisher's exact test를 시행한 후, 두집단 간에 유의한 차이가 있는 것으로 밝혀진 인격장애 척도 점수에 미치는 Y-BOCS,BDI,BAI점수의 영향을 알아보기 위하여 다중선형회귀 분석을 시행하였다. 결 과 : 1) Fisher's exact test 결과 강박증 환자군은 정상 대조군에 비해 경계성 인격장애(18.6%vs 0%, p=0.007). 회피성 인격장애(55.9% vs 18.8%, p=0.001), 우울성 인격장애(40.7% vs 0%, p=0.000)의 비율이 유의하게 높았다. 2) 다중선형회귀분석 결과 Y-BOCS 점수 (t=2.10, p=0.043)와 BAI점수(t=2.60, p=0.014)는 경계성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 또한 BAI점수(t=3.23, p<0.003)는 회피성 인격장애 저수에, BDI점수 (t=3.08, p=0.004)는 우울성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 결 론 : 강박증 환자군은 정상 대조군에 비해 회피성 인격장애, 우울성 인격장애, 경계성 인격장애의 동반율이 높고, 강박증이 경계성 인격장애의 심각도에 유의한 영향을 미치는 것으로 사료된다. The purpose of this study was to assess the comorbid axis-Ⅱ disorders of obsessive compulsive disorder(OCD) patients and to investigate the relationship between symptoms of OCD and the comorbid personality traits. The subjects were 59 patients who met DSM-IV criteria for obsessive-compulsive disorder and 32 normal controls. All subjects completed personality Disorder Questionnaire-IV(PDQ-IV). The patients completed Beck Depression Inventory(BDI) and Beck Anxiety Inventory(BAI), and were rated with Yale-Brown Obsessive Compulsive Scale(YBOCS). The results were as follows. 1) The OCD patients showed significantly higher prevalence of avoidant, depresssive and borderline personality disorder(p<0.01) compared to controls. 2) The BAI score had significant effect on the avoidant personality score(t=3,23, p<0.003). The BDI score had significant effect on the depressive personality score(t=3.08, p=0.004). The YBOCS(t=2.10, p=0.043) and BAI(t=2.60, p=0.014) scores had significant effects on the borderline personality score. We found that OCD patients had higher prevalence of avoidant, depressive, and borderline personality disorders. We also found that obsessive-compulsive symptoms have significant effect on the severity of borderline personalty traits. We suggest that it would be very helpful to consider Axis-Ⅱ disorders for managing patients with obsessive-compulsive disorder.

This study was conducted to measure and compare the salivary cotinine concentration between smokers and nonsmokers, and to investigate the effect on the exposure to environmental tobacco smoke(ETS) with housewives, living on an apartment of Korea. Saliva samples were taken from all volunteers and salivary cotinine was analyzed by a developed radioimmunoassay(RIA) method. The median salivary cotinine levels were 52.8±12.6 ng/ml and 44.6± 9.7 ng/ml in male smokers and in female ones, respectively, and they were 4.3±2.1 ng/ml and 2.9±3.1 ng/ml in male nonsmokers and in female ones, respectively. In addition, average salivary cotinine levels were 3.8±2.7 ng/ml in housewives from smoking homes and 2.4±2.4ng/ml in ones from nonsmoking homes. Results obtained from the analysis of salivary cotinine demonstrate that smokers had a significantly higher concentration of salivary cotinine than nonsmoker. But, there was no significant difference in the salivary cotinine concentration for housewives living in apartment between with smoking husband and with nonsmoking husband.
