The purpose of this study was to evaluate the mechanical and anti-microbial properties of newly prepared chitosan G for human gingival fibroblast. Compressive strength, diametral tensile strength and tensile strength of specimens of resin composite, with or without chitosan G incorporated, were measured. Using a SEM (S-4700, Hitach, Japan), pictures of microbes were taken and adherent capability of microbes to the surface of resin composite was investigated. The results were as follows; 1. The values of compressive strength, diametral tensile strength and tensile strength, composite resin containing 7㎎/㎖ chitosan G were higher than the control group(p>0.05) but composite resin containing 40 ㎎/㎖ chitosan G were either the same or lower than the control group(P<0.05) 2. The MIC of newly prepared chitosan G for S mutans KCTC 3065 and C albicans KCTC 7965 were more than 2 ㎎/㎖. 3. The adherent capability of microbes significantly decreased as the amount of chitosan G increased in the test specimens compared to the control group for C aibicans KCTC 7965 (P<0.05) but there was no statistical significance for S mutans KCTC 3065(p>0.05) . 4. The cytotoxicity of newly prepared chitosan G for human gingival fibroblast was not showed. In conclusion, resin composite with chitosan G incorporated did not show any statistically significant difference for mechanical properties (p>0.05) but it showed a significant antimicrobial effect against C albicans (P<0.05).

최석구,신상구,박찬웅 대한화학요법학회 1984 대한화학요법학회지 Vol.2 No.2

The pharnacokinetic characteristics of 3 different gentamicin formulations, supplied from 3 different producers in Korea, were studied in 15 healthy male volunteers after a single intramuscular injection with a dose of 80mg. Serial serum drug lerels were analysed using a one compartmental open model. Serum gentamicin levels of "C" formulation were higher than those of other formulations. Pharmacokinetic parameters such as absorption rate constant, elimination rate constant and serum half-life for 3 formulations, were nearly identical. Bct areas under the curves(AUC's) for 3 formulations showed significant differences among them. Relati\-e avaiiahilities of "A" and "B" formulation to "C" formulation were 0. 67 and 0.44, respectively. So, it was considered that the differences in serum drug levels after an intram- uscular injection of gentamicin from 3 different producers might be due t o the differences in formulations or manufacturing processes.

崔宗煐,李定均,徐維憲,朴贊雄 大韓神經精神醫學會 1981 신경정신의학 Vol.20 No.1

Plasma chlorpromazine level and some aspects of the clinical significane were studied with 20 schizophrenics. The results were as follows; The (so-called) steady state of plasma chlorpromanzine level was arrived at about 12th day of the drug administration in a dose of 300mg/day on a fixed maintenane regimen. Thereafter the level tended to decline slightly. After arriving at the steady state, a significant positive correlation was observed between the plasma level and the dose of the drug, both in intra-and interpatient comparisons (r=+0.5855, p<0.025). On a fixed chlopromazine dosage, the plasma levels showed marked interpatient differences both before and after the initial day of the steady state, though the differences were more marked before the period of steady state. No significant positive correlation could be identified between the plasma level and the drug side reaction, though 78% of the observed side reactions were positively related with the plasma level of 1.5 mcg/ml or above. And again, significant positive correlation was not observed between the plasma level and the clinical improvement. So-called 'therapeutic window' was considerably wide ranging between 0.5 to 2.45 mcg/ml of the plasma level.

최수찬,김상아,이정은,박웅섭 大韓産業醫學會 2007 대한직업환경의학회지 Vol.19 No.4

목적: 사회복지사의 직무스트레스 실태를 알아보고,복지시설 유형과 직업조건에 따른 직무스트레스의 차이를 조사하고자 하였다. 방법: 서울시 소재 681개 사회복지시설에 근무 중인 사회복지사를 대상으로 우편설문을 시행하였으며 ,최종 분석 사용된 설문지는 총 432부였다. 한국인 직무스트레스 측정도구(KOSS)의 단축형을 사용하여 직무스트레스를 측정하였고,빈도분석,t-test,ANOVA 분석을 실시하였다. 결과: 노인복지시설의 경우 타 기관에 비해 직무요구,직무자율성결여,보상부적절로 인한 스트레스 수준이 모두 높게 나타났다. 작업조건별로는 업무형태,근무시간, 정규휴식시간,직위에 따라 직무스트레스 수준에 차이가 있었다. 서비스와 행정을 둘 다 수행하는 경우에 직무스트레스총점,직무요구,관계갈등,직무불안정,조직체계,보상부적절, 직장문화 영역의 직무스트레스 수준이 높았고,근무시간이 10시간 이상인 경우에 직무요구 영역에서 ,일선 및 선엄사회복지사가 직무자율성결여 및 보상부 적절로 인한 직무스트레스 수준이 높게 나타났다,또한 정규휴식시간 유무에 따라서는 직무스트레스 총점 및 직무스트레스의 7개 하위 영역 모두에서 유의한 차이가 있었다. 결론: 사회복지사의 직무스트레스를 적절한 관리하기 위해서는 서비스와 행정업무 병행에 대한 조치 및 정규휴식시간 확보가 필요하고,특히 노인복지시설 사회복지사의 직무스트레스에 대한 적절한 관리가 필요하다. Objectives: To investigate the level and variation of job stress according to social welfare organizations and work conditions among social workers in Seoul. Methods: For this survey, a self-reported questionnaire was administrated to 1,000 social workers working in organizations for social welfare practice in Seoul. A total of 432 completed questionnaires were received (43.2% response rate). Results: Social workers working in welfare organizations for the aged had higher job stress in the areas of job demand, insufficient job control and lack of reward than those in other welfare organizations. In addition, higher job stress was found in those in charge of both service and administrational work, without regular time for rest, working over 10 hours, in the frontline and senior grade. Conclusions: This study confirms the importance of guaranteeing regular time for breaks in the work schedule and of considering the service and administrational work ratio in job arrangement in order to alleviate stress of social workers.

정신분열증 환자에서 주관적 음성증상경험의 임상적 의의

김지웅,김찬형,구민성,손석한,박진철,최문종,이은철,윤도준,이홍식 대한신경정신의학회 1999 신경정신의학 Vol.38 No.1

연구목적 : 현재까지 정신분열증의 음성증상평가는 주로 객관적인 평가에만 의존해왔기 때문에, 환자들이 주관적으로 직접 경험하는 음성증상의 평가는 경시된 경향이 있었다. 그러나 실제 많은 정신분열증 환자들은 음성증상을 자가하고 있다. 특히, 개관적인 양성 및 음성증상이 관찰되지 않는 경우에도 환자 본인은 음성증상으로 괴로워한다는 이전의 연구보고들이 있었다. 따라서 저자들은 주관적인 음성증상경험과 개관적인 양성증상 및 음성 증상, 우울증상, 불안증상, 추세외로증상과의 상관성을 알아봄으로써 정신분열증의 정신병리에 있어 주관적 음성증상의 존재를 규명하고, 정신분열증 정신병리의 발생기전을 유추해보며 이차적 음성증상과의 관계를 규명하고자 하였으며. 이러한 연구가 정신분열증 정신병리를 이해하는데 도움을 줄 수 있을 뿐 아니라 환자를 공감적으로 이해하는데 도움을 줄 수 있을 것으로 생각되어 본 연구를 시행하였다. 방 법 : DSM-Ⅳ 진단기준의 정신분열증 진단기준에 해당하는 환자를 대상으로 하였다. 주관적인 음성증상의 평가를 위해서 Scale for the Subjective Experience of Negative Symptoms : Korean version(KSENS)을 이용하였고, 개관적인 정신분열증 정신병리의 평가는 Positive and Negative Syndrome Scale(PNASS)를 이용하였다. 우울증상, 불안증상, 추세외로증상의 평가를 위해서 각각 Hamilton Rating Scale for Depression(HAM-D), Hamilton Rating Scale for Anxiety(HAM-A), Extrapyramidal Symptoms Rating Scale(ESRS)을 이용하였다. 각 정신병리척도 점수간의 상관성은 Spearman 상관계수를 이용하여 분석하였다. 결 과 : K-SENS 24항목 중에서 환자가 이를 불편한 것으로 경험하고 있는 항목의 비율과 PANSS 양성척도점수 사이에는 유의한 상관점이 있었으며 (r=-0.40, p〈0.05), 양성증상 중에서도 특히 과대성(r=-0.46, p〈0.05), 의심/피해(r=-0.34, p〈0.05), 적개심(r=-0.52, p〈0.05) 등의 증상과 유의한 상관관계를 보였다. K-SENS 24 항목 중에서 환자가 이를 불편한 것으로 경험하고 있는 항목의 비율과 PANSS 전체점수(r=-0.25, p〉0.05), PANSS 음성척도점수(r=-0.20, p〉0.05), PANSS 일반정신병리척도(r=-0.08, p〉0.05),와는 각각 유의한 상관성이 없었다. K-SENS 24항목 중에서 환자가 이를 불편한 것으로 경험하고 있는 항목의 비율과 HAM-D 점수(r=-0.01, p〉0.05), HAM-A 점수(r=-0.11, p〉0.05), ESRS 총점(r=0.34, p〉0.05)은 각각 유의한 상관성이 없었다. 결 론 : 본 연구결과에서, 정신분열증 환자들이 불편한 것으로 경험하는 주관적 음성증상과 과대성, 의심/피해, 적개심 같은 양성증상은 역상관관계가 있었으며, 이러한 결과를 바탕으로 양성증상이 주관적으로 불편하게 느끼는 음성증상에 대한 가능성과, 혹은 양성증상이 심할 경우, 이에 압도되어 음성증상을 주관적으로 느끼지 못할 수 있다는 가능성이 시사되었으며, 향후 종적인 연구를 통해 이를 규명해 볼 필요성이 제시되었다. 주관적인 음성증상경험과 우울증상, 불안증상, 추세외로 증상과는 상관성이 없는 것으로 나타나서 이들 증상과는 독립적인 증상임을 시사한다. Objective : Since the evaluation of negative symptoms has depended on the clinician's objective observation, the patients subjective experience of negative symptoms has been neglected. However, in fact, a lot of patients are aware of their negative symptoms. There are several reported suggesting that patients suffer from the subjective experiences of their deficit symptoms, even though the objective positive and negative symptoms cannot be observed. Under these circumstances, we have attempted this study with the idea that it would be helpful in understanding the psychopathology of schizophrenia. Also it would help clarifying the relationship between subjective experience of negative symptoms and objectives positive and negative symptoms, depression anxiety symptoms, and extrapyramidal symptoms. Method : All the 37 patients satisfied the diagnostic criteria of DSM-Ⅵ for schizophrenia. The subjective experiences of negative symptoms were evaluated using Scale for the Subjective Experience of Negative Symptoms : Korean version(KSENS), and for the depression, anxiety, extrapyramidal symptoms, we used Hamilton Rating Scale for Depression(HAM-D), Hamilton Rating Scale for Anxiety(HAM-A), and Extrapyramidal Symptoms Rating Scale(ESRS). The correlation between each psychopathology was tested by calculating Spearman correlation coefficient. Results : There was a significant correlation between the ratio of items experienced as uncomfortable symptoms among 24 items of K-SENS, and the score of PANSS positive subscale(γ=-0.40, p〈0.05), Among the positive symptoms, grandiosity(γ=-0.46, p〈0.05), suspiciousnes/persecution(γ=-0.34, p〈0.05), and hostility(γ=-0.52, p〈0.05) showed a significant correlation with the ratio of items experienced as uncomfortable symptoms among 24 items of K-SENS. There was no significant correlation between the ratio of items experienced as uncomfortable symptoms among 24 items of K-SENS, and PANSS total score(γ=-0.25, p〉0.05), or negative subscale score(γ=-0.20, p〉0.05), or general psychology subscale score(γ=-0.08, p〉0.05), respectively. There was no significant correlation between ratio of items experienced as uncomfortable symptoms among 24 items of K-SENS, and HAM-D(γ=-0.01, p〉0.05), or HAM-A(γ=-0.11, p〉0.05), ESRS(γ=0.34, p〉0.05), respectively. Conclusion : These revealed that the negative correlation between the subjective negative symptoms experienced as an uncomfortable ones and the objective symptoms such as grandiosity, suspiciousness/persecution, and hostility. From these results, the possibility that positive symptoms are used as a defense to hide from the negative symptoms because they are overwhelmed by their positive symptoms, is suggested. These results also suggest that subjective experiences of negative symptoms are independent from depression, anxiety and extrapyramidal symptoms.

새로운 물질이 개발되어 신약으로 탄생하기까지 많은 시간과 노력, 예산이 필요하다. 최근, 우리 나라에서도, 신약캐발이 어릴고 힘든 분야이지만 새로운 신약개발을 총해 얻어지는 분가가치가 막대함을 인식, 연구에 박차를 가하 있는 실정이다. 본 연구는, 의약품 개발 선진국인 미국 FDA에서 발행하는 참고자료 중 항균제 임상편가에 대한 가이드라인 및 주요 임상적응증별 항균제 기발(지역사획회득성 폐렴, 원내감염성 계렴, 급성기관지염의 2차세균감염, 만성기지염의 급성세균성 악화, 연쇄구균에 의한 인두영 및 편도염 , 단순성 요로감염증, 복합성 요로감염증 및 신우신영, 급성 세균성 부비동옆, 항 바이러스제 개발시 전임상단계에서 고려사항, 항 바이러스제 허가와 된련 잉상적 고려사항, 카레타 괸련 혈류감염)에 있어서의 파이드라인 등의 자료를 소개함으로져, 향후 제약사의 항균제 신약개발 및 허가 신청된 의악품의 전임상차료 및 잉상시험자료의 검토 평가업무에 참고자료로 활용될 수 있을 것이다. Changing or unclear interpretations of clinical trial data needed to demonstrate the effectiveness and safety of antimicrobial drug products have a times led to confusion and frustration on the part of both applicants and division of these drug products reviewers. The FDA published guidance on desing clinical protocols, implementing, and analyzing data from clinical trials for antimicrobial drug products has been presented and additional companion guidances introduced specific issues to individual infections. This document provides applicants and reviewers with minimal information appropriate for the clinical development of routine antimicrobial drug products and identifies issues common to many antimicrobial drug applications. The agency can use the kind of information to determine whether the antimicrobial drug product under study is safe and effective in the treatment of the specific infection studied.

김영남,김은화,최용우,이용웅,박찬국 조선대학교 2000 The Medical Journal of Chosun University Vol.25 No.2

Gastric volvulus is a rare disorder of stomach, in which stomach twists upon itself. This condition has two types(organoaxial and mesenteroaxial) that can be classified according to axis of rotation, and organoaxial type is more common. Clinical features are suddenly severe abdominal pain in acute onset and nonspecific vague abdominal discomfort in chronic form. It can be diagnosed by barium study and endoscopy with clinical symptoms. The treatment of patients with gastric volvulus has endoscopic reduction or surgical correction of the underlying abdominal pathologic feature predisposing to volvulus formation. We recently experienced a case of chronic onset of gastric volvulus which was confirmed by endoscopy and barium enema. It was failed by endoscopic reduction and corrected completely by laparoscopic gastropexy.
