Reverse Twin Block을 이용한 III급 부정교합의 치료증례

양규호,안상현 大韓小兒齒科學會 1993 大韓小兒齒科學會誌 Vol.20 No.2

The occlusal inclined plane is the fundamental functional mechanism of the natural dentition. Twin blocks are bite blocks that effectively modify the occlusal inclined plane to induce favorably directed occlusal forces by causing a functional mandibular displacement. Reverse twin blocks may be used to correct sagittal relationships in ClassⅢ malocclusion. The upper bite block is designed to procline upper incisors and ClassⅢ intermaxillary or extraoral traction may be also applied. The patient who was treated with reverse twin block, and following results were observed: 1. Anterior crossbite was corrected by labioversion of maxillary incisors and linguoversion of mandibular incisors. 2. Forward maxillary growth was enhanced, and normal molar relationship was established by mesial drift of maxillary 1st molar and distal drift mandibular 1st molar. 3. Lower anterior facial height was increased in the patient who had horizontal growth pattern, and profile was improved.

Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

당뇨병 백서의 간세포에서 Glucokinase 활성도 및 유전자 발현에 대한 인슐린의 영향

강성이,팽정령,서광식,안규정,우정택,김성운,양인명,김진우,김영설,김광원,최영길 경희대학교 유전공학연구소 1993 遺傳工學論文集 Vol.5 No.-

목적 당대사의 조절 상태에 따른 생체 변화를 분자 수준에서 이해하고자 식이 조건을 달리한 정상 백서와 화학적으로 유도된 당뇨병 백서의 간조직에서 혈당수준과 인슐린치료 정도에 따라 나타나는 글루코키나제 활성도 및 유전자 발현을 분석하였다. 방법 스트렙토조토신 정맥투여 후 당뇨병의 유발을 확인하고, 인슐린을 1일 3회 3일간 복강내로 투여하여 상태를 안정시킨 후, 인슐린 투여군은 인슐린 투여 6시간이내에 그리고 인슐린 비투여군은 24시간 후 단두하여 채혈하고 복강을 열어 간조직을 채취하였다. 채취한 간조직에서 글루코키나제 활성도는 인산화된 포도당에서 NADH의 형성을 형광분광계로 측정하였으며, 글루코키나제 유전자 mRNA발현은 Northern 분석법을 이용하였다. 성적 정상 백서에서 공복상태와 식이를 섭취한 경우에 간조직의 글루코키나제 효소의 활성은 차이가 없었으나, 글루코키나제 유전자 mRNA 발현은 증가되었다. 당뇨병이 유발된 백서의 간조직에서 글루코키나제 효소의 활성 및 글루코키나제 유전자의 mRNA 발현은 정상 백서에 비하여 낮았다. 인슐린 투쳐 후 글루코키나제 효소의 활성 및 글루코키나제 유전자의 mRNA 발현이 증가되었고, 특히 혈당이 정상화된 경우에서 글루코키나제 유전자의 mRNA 발현이 증가도었다. 결론 인슐린에 의한 간조직에서 글루코키나제 효소의 활성 및 글루코키나제 유전자의 mRNA을 증가를 볼수 있었다. 당뇨병 백서에서 인슐린 투여 후에 혈당조절이 안된 경우 간조직의 글루코키나제 유전자의 mRNA 발현이 증가가 없는 것으로 보아 글루코키나제 mRNA의 발현에는 인슐린 이외의 다른 요소가 관여할 것으로 생각된다. The liver-specific hexokinase isoenzyme, referred to as glucokinase, is thought to play a key reglulatory role in hepatic glucose metabolism. The glucokinase gene is, therefore, of interest both because of its tissue-specific expression and because of the several regulatory processes that can be analyzed. The level of hepatic glucokinase activity appears to be determined essentially by regulation of the rate of enzyme synthesis, with insulin playing a leading role as an inducer. We investigated the role of insulin for the induction of glucokinase in the liver of diabetic rats. Experimental diabetes was induced by injection of streptozotocin 7 days before the experiment. Regular insulin was given by three days intraperitoneal injection at 8-h interval. The glucokinase mRNA in the liver was estimated by Nothern blot assay, as well as by fluorometric enzyme activity assay. Glucokinase activity was not reduced in the liver of normal fasting rats as compared to normal fed rats. And glucokinase activity was reduced in the liver of diabetic rats as compared to normal rats. In diabetic rats treated with insulin, glucokinase enzyme activity were increased. But glucokinase mRNA expression was only increased in normoglycemic diabetic rat with treated with insulin as compared to hyperglycemic rat. These data indicate that insulin stimulates hepatic glucokinase enzyme activity and mRNA expression. But other hormonal or metabolic factors may be contribute to regulation of glucokinase mRNA expression.

목 적: 본 연구는 대한방사선종양학회지 게재 논문의 통계 오류 현황을 파악하고 이에 근거한 문제 제기를 통해 학회지의 학술적 발전에 기여하고자 하였다. 대상 및 방법: 2006∼2007년 사이에 대한방사선종양학회지에 게재된 총 77편의 논문을 연구 대상으로 하였다. 각각의 논문에 적용된 통계 방법론의 적정성 평가는 통계점검표를 활용하였다. 통계점검표에는 연구의 종류, 통계기법의 사용 범위, 각 논문에 적용된 통계 기법의 종류, 통계적 기법 적용의 타당성 항목이 포함되었다. 통계 오류는 ‘생략의 잘못’과 ‘시행의 잘못’ 항목으로 나누었다. 한 논문에서 서로 다른 항목이 여러 가지 관찰된 경우 각각 횟수로 측정하였다. 같은 항목이 2회 이상 측정된 경우 1회로 횟수를 측정하였다. 통계 전문가가 개별 논문을 대상으로 통계점검표를 작성하였다. 일차 평가자가 방사선종양학 전문가가 아닌 것에서 올 수 있는 평가 오류가 있을 수 있으므로 개별 통계점검표는 간행위원회에서 한 차례 더 세부 점검을 하였다. 작성된 통계점검표의 통계 분석은 SAS (version 9.0, SAS Institute, NC, USA) 소프트웨어를 이용하였고 빈도분석을 시행하여 각 항목의 빈도와 백분율을 산출하였다. 결 과: 총 77편 중 원문을 다운로드 할 수 없었던 4편을 제외한 73편의 게재 논문을 대상으로 평가하였다. 증례보고는 5편, 원저 논문은 68편이었다. 대상 논문 중 46편의 논문에서 통계적 추론을 사용하였고, 16편의 논문에서 단순한 기술통계를 사용했으며, 11편의 논문에서는 통계적 기법을 사용하지 않았다. 추론통계를 사용한 46편의논문에서 사용된 추론통계의 횟수는 각각 분할표분석 17회(37.0%), 비교통계분석 23회(50.0%), 회귀분석 7회(15.2%), 상관분석 5회(10.9%), 생존분석이 27회(58.7%)였다. 통계 기법을 활용하여 연구 결과를 분석할 때 통계적용의 오류가 없는 논문은 19%였다. ‘생략의 잘못’은 34편(50.0%)의 논문에서 총 50회 관찰되었다. ‘시행의 잘못’은 35편(51.5%)의 논문에서 총 47회 관찰되었다. ‘생략의 잘못’과 ‘시행의 잘못’이 모두 발견된 논문은 21편 (30.9%)이었다.결 론: 대한방사선종양학회지에 게재된 논문에서 통계 분석 과정의 다양한 영역에 걸쳐 크고 작은 통계적 오류가 있음을 확인하였다. 향후 대한방사선종양학회지 투고 논문의 심사 과정에서 통계 오류에 관한 적절한 심사를 추가하는 것이 필요하다고 판단된다. Purpose: To improve the quality of the statistical analysis of papers published in the Journal of the Korean Society for Therapeutic Radiology and Oncology (JKOSTRO) by evaluating commonly encountered errors. Materials and Methods: Papers published in the JKOSTRO from January 2006 to December 2007 were reviewed for methodological and statistical validity using a modified version of Ahn’s checklist. A statistician reviewed individual papers and evaluated the list items in the checklist for each paper. To avoid the potential assessment error by the statistician who lacks expertise in the field of radiation oncology; the editorial board of the JKOSTRO reviewed each checklist for individual articles. A frequency analysis of the list items was performed using SAS (version 9.0, SAS Institute, NC, USA) software. Results: A total of 73 papers including 5 case reports and 68 original articles were reviewed. Inferential statistics was used in 46 papers. The most commonly adopted statistical methodology was a survival analysis (58.7%). Only 19% of papers were free of statistical errors. Errors of omission were encountered in 34 (50.0%) papers. Errors of commission were encountered in 35 (51.5%) papers. Twenty-one papers (30.9%) had both errors of omission and commission. Conclusion: A variety of statistical errors were encountered in papers published in the JKOSTRO. The current study suggests that a more thorough review of the statistical analysis is needed for manuscripts submitted in the JKOSTRO.

Two carotenoid biosynthetic genes, phytoene synthase (Psy) and carotene desaturase (CrtI) linked via synthetic 2A sequence under control of CaMV 35S promoter (two T0 plants 5 and 6) or β- conglycinin promoter (three T0 plants 7, 13 and 16) were transformed into soybean variety Kwangan. After agronomic and phenotypic selection at early generations, T5 progeny of PAC soybean were analyzed by Southern blot to confirm T-DNA copy numbers. A total of 27 homologous lines derived from one of three T0 plants (line 7 under the control of β- conglycinin promoter) with one copy T-DNA insertion, were separated and planted into greenhouse. Flanking sequence analysis was carried out on one of homologous line 6-2-3 and results indicated the T-DNA was intergenic inserted into chromosome 14 from 10,873,131 to 10,872,998 base of soybean chromosome. T-DNA insertion structure, flanking sequence and inserted gene expressions need to be analyzed in the further study.
