        In vivo study for the hemostatic efficacy and foreign body reaction of a new powder-type polysaccharide hemostatic agent

        Yoonhyeong Byun,Eun Jin Kim,Areum Lee,Young-Ah Suh,Hee Ju Sohn,Jung Min Lee,Jae Seung Kang,Yoo Jin Choi,Youngmin Han,Hongbeom Kim,Wooil Kwon,Jin-Young Jang 대한외과학회 2022 Annals of Surgical Treatment and Research(ASRT) Vol.102 No.2

        Purpose: Various hemostatic agents have been introduced in therapy as postoperative bleeding is a poor prognostic factor for postoperative outcomes. These products can be divided into those that directly promote the hemostatic cascade and those that physically form a barrier by absorbing blood. The latter, powder-type hemostatic agents have the advantages of being inexpensive and more absorbable with less foreign body reactions (FBRs) and are applicable to a relatively wide area. This study was conducted to verify the safety and efficacy of a newly invented polysaccharide product (OOZFIX, Theracion Biomedical), which improves blood absorption and hemostatic effects. Methods: Two separate animal experiments were performed. The first evaluated FBRs histologically at 3 days, 2 weeks, and 4 weeks, after implantation of OOZFIX in rats, and the second compared hemostatic performance of OOZFIX and Arista AH (Bard) in the porcine liver punch biopsy model. Results: We found minimal FBRs in the 3-day group and no reactions in both the 2-week and 4-week groups after implantation of hemostatic agents. The time to hemostasis of OOZFIX was not significantly different from that of Arista AH (median [interquartile range]: 9 [6–10] minutes vs. 8 [6–10] minutes, respectively; P = 0.522). When comparing the serial bleeding grade tendency, there was no statistical difference between OOZFIX and Arista AH (P = 0.656). Conclusion: OOZFIX caused a minimal FBR that disappeared within 2 weeks in vivo, and its hemostatic performance was comparable with that of an existing agent, Arista AH. Further clinical studies are required in the future.

        하악에 발생한 과잉치의 치험례 : A CASE REPORT

        박정아,양규호,,최남기,김선미,장희숙 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.4

        과잉치는 정상치판(dental lamina)의 과도한 증식이 결과로 발생되어, 가족적 성향을 보이며, 쇄골두개이형성(Cleidocranial dysplasia), Gardner 증후군 등의 여러 질환과 관련되어 나타나기도 한다. 그 빈도는 유치열에서 0.3~0.8%, 영구치열에서 1.0~3.5% 이고, 남성에서 호발되며(2:1), 상악에서 더 많이 발생한다(9:1). 상악에서는 mesiodens라고 불리는 중절치 사이의 위치가 가장 흔한 부위이고, 그 다음은 fourth molar와 측절치 부위이다. 하악에서는 소구치 부위가 가장 흔한 부위이고 전치부위에서는 약 2%로 매우 드물게 발생한다. 과잉치의 만기 잔존은 치간 이개, 인접한 치아의 맹출 장애, 치근 흡수 등을 야기하고 과잉치와 관련되어 함치성 낭종이 발생될 수 있으므로 조기진단과 적절한 치료가 중요하다. 본 두 증례는 비교적 드물게 나타나는 하악에 발생한 과잉치로, 하악 전치부와 소구치부에 발생한 과잉치를 발거하고 교정치료를 시행하여 양호한 결과를 얻었기에 보고하는 바이다. Supernumerary tooth was resulted from excessive proliferation of dental lamina and associated with familial tendency and a congenital syndrome such as Cleidocranial dysostosis or Gardner's syndrome. Incidence reports identify a range of 0.3~0.8% in primary dentition. 1.0~3.5% in permanent dentistion with males being affected twice as frequently as females. maxilla nine times as frequently as mandible. The most common supernumeraty tooth is the mesiodens, which located between the maxillary central incisors, and the next common site is the fourth molar and lateral incisors. Supernumerary teeth are uncommon in the mendible, but premolars are the most common supernumerary teeth and occurrence is very rare in the incisor region of the mandible of possibility of diastema and cruption failure displacement. rotation of the associated permanent teeth, root resorption and dentigerous cyst with presence of the supernumerary teeth. In this two case, one supernumerary tooth located in the mandibular incisor region, the other supernumerary tooth located in premolar region. We could get normal alignment of mandibular dentition by extraction and orthodontic treatment.

        복잡 치아종으로 인한 매복치아의 교정적 견인

        박정아,양규호,최남기,김선미 大韓小兒齒科學會 2007 大韓小兒齒科學會誌 Vol.34 No.4

        치아종은 치성 종양 중 가장 흔한 형태로 증상이 없는 경우가 대부분이며 종종 영구치의 매복이나 맹출지연을 유발한다. 이는 치아를 구성하는 법랑질,상아질,백악질,치수로 구성되며,형태에 따라 복합 치아종과 복잡 치아종으로 구분 된다. 복합 치아종은 다수의 작고 치아와 유사한 형태를 지니며 상악 전치부에 호발하고,복잡 치아종은 무정형의 치성 조직으로 구성되어 있으며 전체 치아종의 약 25%를 차지하고 하악 구치부에 호발한다. 치아종의 병인은 확실치는 않으나 국소적인 외상,감염,유전적 요인이 관여할 것이라 추측된다. 치료는 보존적인 외과적 적출술이 추천되며 재발은 거의 없다. 다음의 두 증례는 각각 하악 제 l대구치와 하악 측절치의 맹출 지연을 주소로 본원에 내원한 환아들로,매복치 상방의 복잡 치아종을 외과적 적출술을 시행하고 매복치의 외과적 노출 및 교정적 견인을 시행하여 양호한 결과를 보였기에 보고하는 바이다. Odontomas are the common type of odontogenic tumors and generally are asymptomatic and frequently lead to impaction or delayed eruption of permanent teeth. They are composed of enamel, dentin, cementurn and pulp tissue and are divided into compound and complex according to the morphology of the hard tissues, Compound odontomas consist of varying numbers of small toothlike structure and have a predilection for the maxillary anterior regions. Complex odontomas consist of an unorganized mass of odontogenic tissues and comprise approximately 25 percent of all odontomas and have a predilection for the mandibular posterior regions. The etiology of odontomas is uncertain but hypothesized to involve local trauma, infection and genetic factors. Treatment of odontoma is conservative surgical removal and are little probability of recurrence. These two cases were about the patients with delayed eruption of mandibular first molar and mandibular lateral incisor. We surgically removed odontoma, exposed impacted tooth and guided impacted tooth into normal position by orthodontic traction. At the completion of traction, the mandibular first molar and mandibular lateral incisor was positioned fairly within the arch and complications such as root resorption were not observed.

        구미지역 직업성질환 감시체계

        김성아,김진석,전혜리,정상재,김상우,이채용,함정오,유재영,최태성,하봉구,조민환,우극현 大韓産業醫學會 2003 대한직업환경의학회지 Vol.15 No.1

        목적: 구미지역 내 대학병원이자 특수건강진단·보건관리대행기관의 산업의학전문의, 보건관리대행 간호사, 사업장 간호사를 중심으로 직업성질환감시체계를 구축하여 주요 직업성질환들의 발생현황과 규모를 파악하고자 하였다. 또한 연차적으로 산업, 직업, 업무내용 등에 따른 분포나 원인을 기존 자료원(특수건강진단의 직업병 유소견자와 산재요양승인 되는 직업병자)과 비교하여 분석·기술하고 예방 및 관리를 포함한 보건의료기술개발까지을 포함하는 종합적인 감시체계를 구축하고 운용하고자 하였다. 방법: 구미지역의 산업적 특성에 맞는 직업성질환감시체계를 구축하고 지역 감시체계의 모델을 제시하였다. 6대 감시대상 직업성질환(독성 간염, 직업성천식, 직업성 근골격계질환, 직업성 피부질환, 직업성 암, 수지진동증후군)의 실행적 환례정의, 보고양식 및 보고체계 개발, 분석양식 및 결과 배포 형식을 개발하였으며, 그 유병규모를 파악하고, 감시질환의 분포 및 특성, 관련인자 등을 분석·기술하고자 하였다. 이때, 1년간의 환례분석시 직업병 유소견자 및 직업병 요양자에 대한 자료와 함께 비교 분석하였으며, 노동통계자료를 이용하여 년간 발생률을 추정하였다. 결과: 2001. 1. 1일부터 2002.4.30일까지 총 287건이 보고되었으며, 직업성 근골격계질환 132건(46.0%), 직업성 피부질환 100건(34.8%), 독성간염 34건 (11.8%), 직업성천식 16건 (5.6%), 수지진동증후군 5건 (1.7%) 이었으며 직업성 암은 한건도 보고되지 않았다. 보고경로별로는 보건관리대행에서 33건 (11.5%), 해당 유해인자별로 실시되는 특수검진 외의 각종 건강진단업무 수행 중 발견된 환례에 대한 보고가 206건(71.7%)이었다. 직종별 분류의 결과는 섬유업종사자, 단순노무종사자, 음식업종사자 등이 다수를 차지하였다. 근골격계질환의 경우, 수근관증후군이 42건(33%), 외상과염/내상과염이 39건(30%)로 가장 많았다. 직업성 피부질환은 97건이 접촉성 피부염으로 유기용제류가 59건(59%)으로 가장 많고, 니켈 및 에폭시수지에 의한 알레르기성 접촉성 피부염이 각각 6건과 5건이었다. 독성 간염은 모두 DMF 나 DMAc에 의한 것으로, 근무시작 후부터 간기능이상이 발견되기까지의 근무기간은 대부분이 3개월 이하이며, 1개월 이하인 경우도 10건이나 되었다. 동 기간 중 감시환례에 대해 산재요양 자료와 중복여부를 확인한 결과, 중복되는 것은 하나도 없었다. 특수건강진단에서 직업병유소견자로 판정된 경우는 독성간염에서 3건이 있었으며, 나머지 질환은 중복되는 것은 없었다. 2001도 구미지역의 근로자수와 보고환례건수를 이용하여 연간 발생률을 추정하였다. 근로자 10만 명당 연간 발생률은 상지 근골격계질환은 63.6명, 피부질환 48.2명, 독성 간염 17.9명, 천식 7.7명, 수진진동증후군 2.4명이었다. 참여예상인원은 총 46명이었으며, 실제 참여자수는 21명, 평균참여율은 46%, 실제 참여 1이당 평균 보고건수는 산업의학전문의가 28건으로 가장 많았고, 대행간호사는 45,건, 사업장 간호사는 3.3건이었다. 결론: 지역 감시체계는 기존 통계자료들에서 발견되지 않았던 직업성질환의 발견에 유용한 통계원이며, 특히 지역의 특성과 여건을 고려하여 체계화된 시스템을 구축하여 운용한다면 더 성과가 클 것이다. Objectives: Area-based occupational disease surveillance in Kumi (KODS) was used to collect data on occupational diseases. The data was used to estimate the magnitude of the diseases, to analyze for their characteristics and to find links for their intervention and prevention. Methods: Since January 2001, occupational physicians and nurses in Occupational Health Service (OHS) have reported six major occupational diseases; occuaptional musculoskeletal disorders of the upper extremities (MSDUE), occupational dermatoses, toxic hepatitis, occupational asthma (OA), hand-arm vibration syndrome (HAVS), and occupational cancer. For the respective diseases, a reporting sheet and operational diagnostic criteria were developed by the KODS. An analysis of the KODS data, collected over a certain period, was compared with data from the Korea Labor Workers Corporation (KLWC) and the Specific Health Examination (SHE), and the incidence rates of the diseases estimated. Results: Between Jan 2001 and Apr 2002, 287 cases of the six major occupational disease were reported. Of these, there were 132 (46.0%), 100 (34.8%), 34 (11.8%), 16 (5.6%), and 5 (1.7%), cases of MSDUE, occupational dermatoses, toxic hepatitis, OA, and HAVS, repectively. But, there were no cases of occupational cancer. 33 (11.5%) of the incidence were reported via the OHS, 206 (71.7%) from health checkups, and the other 48(16.8%) from other routes. The synthetic fibers and electronic components manufacturing industries accounted for the greatest number of reported cases. With resport to occupation, the greatest numbers of incidence were reported from the elementary occupations, textile workers, assemblers, and cooks and food services worker, in that order. Of the MSDUE cases, carpal tunnel syndrome and epicondylitis were the two most common diseases. Most of the occupational dermatoses were due to contact dermatitis, with organic solvents (59%), nickel (6%), and epoxy resin (5%) accounting for the majority of these cases. All cases of toxic hepatitis were induced by dimethylformamide or dimethylacetamide, which were reported by a unique monitoring system. During same period, there were no cases claimed by workers to the KLWC, and only three cases from SHE, were identified. Using data from workers' number and surveillance, the annual incidence of MSDUE, dermatoses, hepatitis, OA, and HAVS, per 100,000 workers were 63.6, 48.2, 17.9, 7.7, and 2.4, respectively. Conclusions: These results show that an area-based surveillance system can be very effective for the collection of data on work-related diseases, at least in Kumi.

      • 초등 과학 생명 영역 내용에 대한 학생들의 의문 유형과 해결방법에 관한 연구

        임채성,최은아,박정인,이수진 부산교육대학교 과학교육연구소 2004 科學敎育硏究 Vol.29 No.-

        In this study, the frequencies and types of questions about LIFE areas of the Science Curriculum of elementary school students were investigated through in-depth interviews with twelve 4th and 5th graders. The results of the research can be summarized as follows: (1) In conjectural question, the proportions of 'object exploration question' and 'object verification question' were high in all of the 4th graders and the students of low achievement level. (2) The numbers of causal questions generated by the 4th graders were much higher than those of the 5th graders. (3) The frequencies of the predictive, methodological, applicative questions were very low both in 4th and 5th grade students. (4) The numbers of conjectural questions were more in all students except the low achievement level of 4th graders at not-yet-taken contents than at already-taken ones. (5) The numbers of causal questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (6) The numbers of the predictive, methodological, applicative questions of the 4th graders were more at not-yet-taken contents than at already-taken ones, whereas opposite trend in the 5th graders. (7) The numbers of students' curriculum-related questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (8) As ways for solving or seeking answers about questions, the 4th graders suggested methods of consulting experts or teachers (23.9%), internet searching (21.6%), and books or science-related encyclopedia (20.3%), while the 5th graders suggested the internet searching (36.5%), consulting experts or teachers (24.8%), and books or science-related encyclopedia (17.7%). Based an these results, we suggest several ways for improving the question-posing abilities of the students and adequate use of students' questions in the process of science teaching learning.
