        대동맥 판막 치환술 후 반복되는 Acinetobacter baumannii 균혈증의 원인이 된 대동맥염 1예

        정용필,김성철,송은희,장은영,김은경,김윤지,성흥섭,김미나,최상호,우준희,김양수 대한감염학회 2007 감염과 화학요법 Vol.39 No.3

        감염성 대동맥염은 흔하지 않지만 매우 위중한 질병으로 Salmonella so.와 S. aureus가 주된 원인균이다. 아직까지 병원내 감염의 주요 원인균인 Acinetobacter baumannii에 의한 감염성 대동맥염은 보고된 바가 없었다. 저자들은 대동맥 판막 치환술을 시행받은 76세 남자 환자에서 적절한 항생제 투여에도 반복되는 A. baumannii 균혈증의 원인이 감염성 대동맥염으로 진단되었던 1예를 경험하였기에 보고하는 바이다. Infectious aortitis is an uncommon yet, life threatening disease. Early surgical treatment and prolonged antibiotic therapy is crucial to survival. Salmonella sp. and Staphylococcus aureus are the most common organisms isolated. There is no case report of infectious aortitis caused by Acinetobacter baumannii, which has recently emerged as a major cause of health care-associated infections. Here, we describe a 76-year-old male with infectious aortitis who experienced recurrent bacteremia due to A. baumannii in spite of adequate antimicrobial therapy after aortic valve replacement.

      • 고추 탄저병 저항성 중간모본 ‘원예 100005호 ’,‘원예 100006호’ 육성

        양은영,김수,채영,채수영,조명철,문지혜,박태성,이우문,곽정호 忠北大學校 農業科學硏究所 2015 農業科學硏究 Vol.31 No.2

        Owing to frequent heavy rain due to abnormal weather, the occurrence of pepper anthracnose has recently increased, which affects the supply and demand of pepper. As a result, the price of red pepper powder in 2011, for example, increased three times compared to the average year. Although anthracnose of pepper plants has been controlled by fungicides until now, it is important to develop new resistant cultivars because of the reduction of the labor force in rural area and occurrence of new anthracnose strains resistant to fungicides. National Institute of Horticultural and Herbal Science developed two pepper lines, ‘Wonye 100005’ and ‘Wonye 100006’ that are resistant to pepper anthracnose. These lines were developed by continuous selection of progenies from a cross between ‘Wonye AR1’, which were developed from interspecific hybridization and ‘TF68’. The anthracnose resistance level of the two lines was higher than that of commercial cultivars and similar to check varieties showing highest level of anthracnose resistance.

        The purpose of this study was to identify whether shoulder complex exercise program with visual feedback could improve the shoulder muscular strength and postural alignment in adolescents with shoulder asymmetry. Twenty eight subjects were recruited from the K university and divided into three groups: experimental 1, 2group(Each n=10) and control group(n=8). For 4 weeks, the experimental group 1 performed shoulder muscle complex exercise program and the experimental group 2 performed shoulder complex exercise program with visual feedback. The control group did not perform exercises. The shoulder muscle strength and difference between the height of left and right shoulders were assessed before, after training using the hand-held dynamometer and Global Posture System. Subordination variables, general characteristics analysis, χ² test and Kruskal Wallis H test were conducted to evaluate differences between groups and training before, after changes were checked Wilcoxon signed rank test with using the PASW 18.0 statistical program. The results of the study were as follows. 1) Both the experimental 1, 2group showed improvements in muscle strength of several muscles following training (p<.01). The control group showed significant reduction in the left posterior deltoid (p<.05), and did not show significant changes in examining other muscles (p>.05). And there were differences among three groups in shoulder muscle strength (p<.001). Muscle strength changes in several muscles were greater in the experimental 1, 2group compared with the control group (p<.001). Muscle strength changes in the several muscles were greater in the experimental group 2 compared with the experimental group 1 (p<.001) 2) Both the experimental 1, 2group showed significant decreases in the difference between the left and right shoulder heights following training (p<.01). The control group did not show change (p>.05). Changes in the difference between the left and right shoulder heights were greater in the experimental 1, 2group compared with the control group (p<.001).

        A change in the living pattern is happening in the flow of sudden changes of a modern society. That is the development of the communications by internet and the social relationship. Internet is not only the space that can fulfill lacking mental actions within friends in adolescence periods, but also it is used for a meeting place for friends and a place to escape from reality while transcending time and space. According to its equal characteristic not as hierarchic as adults, a friendship in adolescence accelerates social abilities and helps solving problems in social adaptations. Therefore, by investigating such friendships according to sex, school and the levels of internet addiction and the difference in adolescence's online homogeneous and heterogeneous friendships, thee exists a purpose to understand adolescence's friendships and help direct their friendships in a stable and desirable way. The samples chosen far this research were 319 students(150 males and 169 females) from 8 different co-ed middle and high schools located in Seoul, Korea. The apparatus used for measurements were the quality measure from Lee, Eun-Hae(1999) of friendships which is edited by Nam, Yoon-Ju and the questionnaire for internet addiction that was improved from the measure Young(1996) by Kang, Min-Chul and Oh, Ik-Soo(2000) and developed exclusively oir Korean adolescence were used in order to investigate the levels of internet addiction of adolescence. The collected data were used by SPSS 10.0 statistic program. In order to find out the samples' demographic background, several factors such as frequency, percentage, mean and standard deviation were produced and In order to verify the reliance of the apparatus, each measure's Cronbach's a coefficient was produced. Also, t-test was used to find out if there is a difference in homogeneous and heterogeneous friendships according to sex, school and internet addiction levels. The results of this study are as follows: 1) After looking at any difference in both online homogeneous and heterogeneous friendships by adolescence's sex, there was a significant difference. For online homogeneous friendships, male students were sensible of conflicts and as well as for heterogeneous friendships, male students were sensible even highly in such areas as mental stability, trust, assistance, recognition, enjoyment of friendship, competition and satisfaction. 2) After looking at any difference in both online homogeneous and heterogeneous friendships by adolescence's grade level, the homogeneous friendships didn't show any signifiant difference, but the heterogeneous friendships did show some distinctive differences. 3) After looking at any difference in both online homogeneous and heterogeneous friendships by adolescence's level of internet addiction, there wasn't any significant difference at all.

        자일리톨 섭취에 따른 Streptococcus mutans의 글루칸 생성관련 유전자 발현 억제효과

        김지혜,이영은,안상헌,최연희,남순현,송근배 大韓小兒齒科學會 2009 大韓小兒齒科學會誌 Vol.36 No.4

        본 연구에서는 장기적인 자일리톨의 섭취가 Streptococcus mutans의 대표적인 독성인자 중 하나인 글루칸 생성에 미치는 영향을 알아보기 위하여 글루칸 합성효소인 glucosyltansferase의 mRNA 발현을 실시간 역전사 중합효소 연쇄반응을 통해 평가하여 다음과 같은 결과를 얻었다. 1. 24개월 동안 자일리톨껌을 섭취한 군에서 타액 내 Streptococcus mutans의 colony 수는 통계적으로 유의하게 감소하였다(p<0.05). 2. 비수용성 글루칸 합성에 관여하는 유전자인 gtfB, gtfC의 발현은 자일리톨껌을 섭취한 군에서 시간이 지남에 따라 유의 하게 감소하였다(p<0.05). 특히 gtfB의 발현은 12개월과 24개월째 대조군에 비하여 통계적으로 유의하게 낮았고, gtfC의 발현은 24개월째 대조군에 비하여 통계적으로 유의하게 낮았다(p<0.05). 3. 수용성 글루칸 합성에 관여하는 유전자인 gtfD의 발현 역시 자일리톨껌을 섭취한 군에서 시간이 지남에 따라 유의하게 감소하였다(p<0.05). 또한 gtfD의 발현은 12개월과 24개월째 대조군에 비하여 통계적으로 유의하게 낮았다(p<0.05). 이상의 결과들을 종합해 보았을 때, 자일리톨의 섭취는 구강 내 Streptococcus mutans의 글루칸 합성 관련 유전자들의 발현을 억제시킴으로써 Streptococcus mutans의 수적인 감소를 가져오는 것으로 생각된다. Xylitol has the ability to reduce the adherence of Streptococcus mutans(S. mutans), which can make it easier to remove plaque, decrease acid production and inhibit dental caries. There are few reports on the effects of xylitol on the expression of the virulence related genes in S. mutans. This study examined the inhibitory effect of chewing gum containing xylitol on glucan synthesis related gene expression of S. mutans. Participants were voluntarily recruited for a women's oral health prevention program, classified into two groups(a control and a xylitol group), and then followed for 2 years. Twenty salivary samples were randomly selected from each group. Colony count and real-time reverse transcription polymerase chain reaction were used to analyze the characteristics of S. mutans. The following results were obtained: The S. mutans counts decreased steadily in the xylitol group over the study period(p<0.05). The expression of the virulence related genes (gtfB, gtfC and gtfD) was significantly lower in the xylitol group than in the control groups (p<0.05). In conclusion, these results suggest that chewing xylitol gum for a long period of time may reduce the expression of the genes associated with S. mutans virulence, which can result in a decrease growth of S. mutans colonies as a result.

        Purpose: To develop the patient classification system based on the resource utilization for reimbursement of long-term care hospitals in Korea. Method: Health Insurance Review & Assessment Service (HIRA) conducted a survey in July 2006 that included 2,899 patients from 35 long-term care hospitals. To calculate resource utilization, we measured care time of direct care staff (physicians, nursing personnel, physical and occupational therapists, social workers). The survey of patient characteristics included ADL, cognitive and behavioral status, diseases and treatments. Major category criteria was developed by modified delphi method from 9 experts. Each category was divided into 2-3 groups by ADL using tree regression. Relative resource use was expressed as a case mix index (CMI) calculated as a proportion of mean resource use. Result: This patient classification system composed of 6 major categories (ultra high medical care, high medical care, medium medical care, behavioral problem, impaired cognition and reduced physical function) and 11 subgroups by ADL score. The differences of CMI between groups were statistically significant (p<.0001). Homogeneity of groups was examined by total coefficient of variation (CV) of CMI. The range of CV was 29.68-40.77%. Conclusions: This patient classification system is feasible for reimbursement of long-term care hospitals.
