        Purpose: To investigate the clinical outcomes of refixation of a dislocated intraocular lens (IOL) and IOL exchange with intrascleral fixation. Methods: We performed a retrospective study of 90 patients (91 eyes) who underwent refixation or exchange of IOLs from January 2014 to April 2019. The patients were divided into an ab externo scleral refixation group (group 1), an intrascleral refixation group (group 2), and an exchange with intrascleral fixation group (group 3). We evaluated the best-corrected visual acuity (BCVA), spherical equivalent, cylindrical power, intraocular pressure, and postoperative complications. Results: The BCVA was 0.10 ± 0.17 (group 1), 0.15 ± 0.29 (group 2), and 0.31 ± 0.52 (group 3) at 6 months after surgery. The BCVA change in group 3 was significantly greater than that in groups 1 and 2 (p = 0.018 and p = 0.046, respectively). The final BCVA was not significantly different among the groups (p = 0.422). The spherical equivalent was -1.26 ± 1.72 diopters (D) (group 1), -1.32 ± 2.09 D (group 2), and -0.17 ± 1.58 D (group 3) at 6 months after surgery, showing that group 1 and group 2 were more myopic than group 3 (p = 0.004 and p = 0.001, respectively). Haptic slippage was the most common complication. Conclusions: Refixation of dislocated IOLs and IOL exchange with intrascleral fixation did not differ significantly in terms of the final visual outcomes. Refixation was associated with more myopia and a higher risk of IOL dislocation or haptic slippage than exchange. 목적: 탈구된 인공수정체 재고정술과 공막내고정술을 이용한 인공수정체교환술에 대한 임상결과를 알아보고자 하였다. 대상과 방법: 2014년 1월부터 2019년 4월까지 탈구된 인공수정체 재고정술 또는 인공수정체교환술을 시행한 환자 90명(91안)을 대상으로 후향적 연구를 진행하였다. 기존 인공수정체로 외부 공막고정술을 시행한 군(1군), 기존 인공수정체로 공막내고정술을 시행한 군(2군), 공막내고정술을 이용한 인공수정체교환술을 시행한 군(3군)으로 나누어 최대교정시력, 구면렌즈 대응치, 난시값, 안압 및 합병증을 관찰하였다. 결과: 최대교정시력(logMAR)은 수술 6개월 후 1군에서 0.10 ± 0.17, 2군에서 0.15 ± 0.29, 3군에서 0.31 ± 0.52로 향상되었다. 최대교정시력의 변화는 1, 2군보다 3군에서 유의하게 높았으나(p=0.018, p=0.046), 최종 최대교정시력은 유의한 차이가 없었다(p=0.422). 구면렌즈 대응치는 수술 6개월 후 1군에서 -1.26 ± 1.72 diopters (D), 2군에서 -1.32 ± 2.09 D, 3군에서 -0.17 ± 1.58 D로 근시화되었고, 3군보다 1, 2군에서 유의하게 더 큰 근시값을 보였다(p=0.004, p=0.001). 합병증 중 지지부 미끄러짐이 가장 많았다. 결론: 탈구된 인공수정체 재고정술은 인공수정체교환술과 비교하여 최종 최대교정시력에서 유의한 차이가 없었다. 인공수정체교환술보다 재고정술에서 더욱 근시화되는 경향이 있었고, 인공수정체 탈구 또는 지지부 미끄러짐의 위험이 높았다.

        on their own judgment and the relevant factors having impact on them. Methods: The questionnaire survey was conducted by visiting the students in 3 colleges in Daejeon and Chungcheongnam-Do. 792 students were finally selected as the subjects. The results were statistically analyzed using the SPSSWIN(ver 13.0) and x2-test, ANOVA and multiple regression analysis were conducted. Results: The usage status of college students showed the significant difference by general features, knowledge and recognition attitude. The knowledge level of students on the general drugs was very low. They had excessive expectation on the general drugs in terms of the recognition attitude. The lowest factor was the distrust on the general drugs. 27.5% of subjects was satisfied with the effect after using 48.1%m when the drugs were frequently used. Those who experienced the side effects accounted for 9.6%. In accordance with the analysis on the factors related to the knowledge on, recognition attitude on and usage status of general drugs, the education had the highest influence on the abuse and misapplication of drugs. For the mistrust factor on the drugs and negligence factor on abnormal response, the gender was the most influencing. The knowledge level was the greatest impact on the excessive expectation factor on the drugs. The factor that the usage status was the most influential was the education on the abuse and misapplication of drugs. Conclusions: The systematic approach including establishment of health policies for the improvement of health and health education activity should be implemented on the basis of the thorough analysis on the knowledge level and recognition on drugs and the factors influencing on the usage of drugs.

        산업장 근로자들의 연령과 건강습관에 따른 비만, 혈압 및 혈청지질의 특성

        조영채,송인순 대한보건협회 2000 대한보건연구 Vol.26 No.2

        This study was performed to monitor the characteristics of the levels of BMI, blood pressure and serum lipids(total cholesterol, triglyceride, HDL-cholesterol and LDL-cholesterol) according to age and health behavior in industrial workers. The subjects for this study were 3,981 industrial workers(male 2,467, female 1,514) who underwent medical examinations at a general hospital in Taejon City. We analyzed the data obtained from medical examinations and questionnaires for their health behavior from January 1, 1998 to December 31, 1999 BMI and blood pressure were lower at the age group of 20s' than those of any other groups of both sexes, and the sequential trends of those showed increasing patterns as the age increased. The level of total cholesterol, triglyceride and LDL-cholesterol were lowest at the age group of 20s'of both sexes, and those levels showed increasing patterns by 50s', but decreased at 60s'. The level of HDL-cholesterol was highest at the age group of 20s', and it gradually decreased by 50s', but thereafter increased at 60s'. In comparison of health practicing group with non-practicing group in terms of health behavior, BMI of non-practicing group was significantly higher than that of practicing group in both sexes. In male, blood pressure was higher in health practicing group than non-practicing group, but it was reversed in female. Total cholesterol and LDL-cholesterol were significantly higher in non-practicing group than in practicing group of both sexes, but they were reversed in the case of HDL-cholesterol. These results of this study suggested that age and health behavior is associated with BMI, blood pressure, and serum lipid levels. Therefore, we need to develop the new programme for the effective practice of health behavior.

        In Vitro 자계(磁界) 측정에 의한 비소화합물의 폐포 Macrophage 독성 평가

        조영채,Cho, Young-Chae 대한예방의학회 1999 Journal of Preventive Medicine and Public Health Vol.32 No.4

        Objectives: This study was conducted to evaluate the cytotoxicity of gallium arsenide(GaAs), indium phosphide(InP) and indium arsenide(InAs) all of which are used a$ the semiconductor eletments in semiconductor industry. Methods: Cytotoxicity id the alveolar macrophage was evaluated by the measurement of in vitro magnetometry, LDH release assay and histological examination. Results: The relaxation curves by the in vitro magnetometry showed that GaAs has the cytotoxicity for the alveolar macrophage which is more significant in the higher dosages, while this cytotoxicity is not appeared in the groups added with InP or InAs or PBS. In the decay constant for two minutes after magnetization, GaAs-added groups showed a significant decrease with increasing doses, but both InP- and InAs-added groups did not show any significance. The LDH release assay showed a dose-dependent increasing tendency in the GaAs-, InP- and InAs-added groups. In terms of cellular morphological changes, GaAs-added groups revealed such severe cellular damages as prominent destructions in cell membranes and their morphological changes of nucleus, while InP- and InAs-added groups remained intact in intracellular structures, except for cytoplasmic degenerations. Conclusions: It is suggested that GaAs is more influential to cytotoxicity of alveolar macrophages than InP and InAs. 본 연구는 반도체 산업에서 반도체소자로서 주목받고 있는 GaAs, InP및 InAs의 세포독성을 평가하기 위해 햄스터의 폐포 대식세포를 사용하여 in vitro 자계 측정, LDH 활성치측정 및 세포의 형태학적 관찰 등을 검토하였다. 세포자계측정 결과 GaAs, InP 및 InAs첨가군 모두 대조군(PBS첨가군)에 비해 완화곡선이 유의하게 지연되었으며, 특히 GaAs 첨가군은 농도증가에 따라 용량의존적으로 완화곡선이 지연되는 경향이었다. 자화 후 2분간의 완화계수는 대조군에 비해 GaAs 첨가군은 농도증가에 따라 유의하게 낮아지는 용량의존성이 높은 경향이었으나, InP 및 InAs 첨가군에서는 모두 유의성이 인정되지 않았다. LDH활성치는 GaAs, InP 및 InAs첨가군 모두 용량 의존적으로 점차 높아지는 경향이었다. 세포의 형태학적 관찰소견은 GaAs첨가군에서는 용량의존적으로 세포막의 현저한 파괴, 핵의 형태적 변화 등 심한 세포장해가 유발된 반면, InP첨가군과 InAs첨가군에서는 세포내의 구조는 유지되었으나 세포질의 변성이 관찰되었다. 결과적으로 GaAs는 InP나 InAs보다 폐포 대식세포의 세포독성이 강한 것으로 보인다.
