It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.

Objective : This research is for evaluating the level of the recognition on the occupational therapy among general people in comparison with physical therapy, and checking the effectiveness of publicity activities occupational therapy in the way of an events. Method : The process were survey and advertisement targeted the group of a hundred of general people in the way of participating the Service Expo in the Chungbuk Y area. Result : There was a meaningful difference not only on the level of recognition and necessity but also on statistical difference from the result of the effectiveness of the advertisement of occupational therapy before and after through the education and exhibition for occupational therapy. Conclusion : Occupational therapy is inferior public awareness and necessity to physical therapy among the public, this level were getting increased after done the advertisements through the events. So We need to keep doing various activities and advertisements on occupational therapy continuously to increase the public awareness. 목적 : 본 연구는 작업치료와 물리치료의 인식도를 비교함으로서 일반인들의 작업치료에 대한 인식수준을 알아보고 행사를 통한 작업치료 홍보 유용성을 알아보기 위함이다. 연구방법 : 충북 Y 지역의 서비스박람회 행사에 참여하여 일반인 100명을 대상으로 설문과 홍보를 실시하였다. 연구결과 : 작업치료와 물리치료의 인식도, 필요성에 유의한 차이가 있었고, 교육 및 전시를 통한 작업치료 홍보 효과에서 홍보 전과 후에 통계적으로 유의한 차이가 있었다. 결론 : 일반인들에게 작업치료는 물리치료보다 인식도 및 필요성이 낮지만 행사를 통한 홍보로 그 수준을 높일 수 있어 다양한 활동 및 홍보가 필요하다 하겠다.

본 실험은 전갈 추출물이 어혈병태 모델과 KCN으로 유발된 전뇌허혈, 뇌세포독성 등에 미치는 영향을 관찰하였다. 전갈은 Dextran에 의해 유도된 혈전으로 감소된 혈소판수, fibrinogen량, hemocrit치를 유의성 있게 증가시키고. 증가된 prothrombin time을 유의성 있게 단축시켰다. 전갈은 thrombin과 ADP에 의해 유도된 혈소판 응집을 억제하였으나 collagen에 의해 유도된 혈소판 응집에는 저해효과를 나타내지 않았다. 또한 collagen과 epinephrine에 의해 유도된 pulmonary embolism에 대하여 보호 효과를 나타내었다. 전갈은 KCN에 의한 전뇌허혈 유발 실험에서 혼수시간을 유의성 있게 단축시켰고, Amyloid β protein(25-35)에 의해 유도된 PC12 세포의 독성에 대하여 보호효과를 나타내었다. This following is effect of Buthus martensi Karsch (BMK) extract on dextran-thrombus model, KCN-induced coma, cytotoxicity of brain etc. BMK extract significantly increased number of platelet and fibrogen and significantly shortened the prothrombin time as compared with control group treated with dextran. BMK extract didn't affect the changes of hematocrit as compared with control group treated with dextran. BMK extract induced a significant inhibition of human platelet aggregation induced by thrombin and ADP but did not affect human platelet aggregation induced by collagen. BMK extract showed a protective effect on pulmonary thrombosis induced by collagen and epinephrine. BMK extract prolonged the duration of KCN-induced coma and showed a protective effect on cytotoxicity of PC12 cells induced by amyloid β protein(25-35) in a dose dependent manner. These results suggested that BMK extract might be usefully applied for prevention and treatement of thrombosis and brain damage.

저자들은 다발성 뇌 농양을 동반한 치명적인 파종성 S. apiospermum 감염이 발생한 간 이식 환자를 경험하였다. 본 증례의 환자는 voriconazole로 치료하는 호전경과를 보이다가 진균성 뇌 동맥류 파열로 사망하였다. S. apio-spermum은 비교적 드문 진균으로 병리학적으로 Aspergillus spp.와 매우 유사하고 amphotericin B에 내성을 나타내므로 진단과 치료가 적절하게 이루어지지 못할 가능성이 많고 면역 기능 저하 환자에서 혈행성 전파를 통한 파종성 감염이 용이하게 발생하므로 높은 사망률을 나타낸다. 이식 환자를 비롯한 면역 기능 저하 환자에서 진균감염이 의심될 때 S. apiospermum과 같은 드문 진균에 의한 감염증도 감별진단에 포함해야 하겠다. Sedosporium apiospermum is a saprophytic fungus commonly found in soil and polluted water. This organism is known as a cause of mycetoma, which may occur in immunocompetent hosts following trauma. However, in immunocompromised patients, S. apiospermum can also cause life-threatening invasive disease, including central nervous system infection or disseminated infection. We report a fatal case of disseminated S. apiospermum infection in a 46-year-old woman after liver transplantation. Eight days postoperatively, she developed pneumonia, followed by altered mentality in the 15 days. A head CT demonstrated multiple brain abscesses. Sputum and stereotactic-aspirated brain abscess culture yielded S. apiospermum. Despite treatment with voriconazole, the patient died of intracranial hemorrhage.

혈관내피세포-U937세포의 부착에 미치는 Eicosapentaenoic Acid의 효과

김은지,전재은,임현주,차성철,정의룡,조용근,조용근 경북대학교 병원 1998 경북대학교병원의학연구소논문집 Vol.2 No.1

연구배경: 역학적연구에서 어류의 섭취가 많은 집단에서 관상동맥질환의 빈도가 낮은 것이 보고되었고, 이것은 어류에 많이 함유된 불포화지방산(polyunsaturated fatty acid) 특히 eicosapentaenoic acid 때문으로 생각되어지고 있다. 본 연구에서는 동맥경화증 발생의 초기단계로 여겨지는 단핵구와 혈관내피세포 사이의 adhesion에 미치는 다불포화지방산의 영향을 in vitro system에서 관찰하고자 하였다. 방 법: 제대정맥에서 얻은 혈관내피세포를 배양하여 96 well에 옮기고 25, 50, 100, 200 ㎛ 농도의 eicosapentaenoic acid(EPA)를 6시간 동안 처리한 U937세포를 부착시켜 adhesion assay를 시행하였다. 혈관내피세포를 자극하기 위해서는 lipopolysaccharide(LPS)를 well당 100 ng씩을 투여하였다. 음성대조군으로는 LPS로 자극하지 않은 혈관내피세포에 EPA처리를 하지 않은 U937세포로 adhesion assay한 성적을 사용했고, 양성대조군으로는 LPS로 자극한 혈관내피세포에 EPA처리를 하지 않은 U937세포로 adhesion assay한 성적을 사용했다. 그리고 EPA(3.3 mM)을 5㎛ CuSO4 및 300 ㎛ asscorbic acid와 혼합하여 섭씨 37도에서 16시간 두어 산화-EPA를 만들어 같은 실험을 반복하였다. 결 과: U937세포에 25, 50, 100, 200 ㎛의 EPA로 6시간 처리하였을 때 U937세포의 생존율은 99% 이상이었다. 혈관내피세포를 LPS로 자극했을 때 adhesion assay에서 혈관내피세포에 붙는 U937세포의 수는 현저히 증가하였다. 그러나 EPA를 U937세포에 25, 50, 100, 200 ㎛의 농도로 6시간 처리 후에 lipopolysac-charide를 처리한 제대정맥 내피세포에 부착(adhesion)시켰을 때 처리한 EPA의 각 농도에 따른 부착된 U937세포의 수는 통계적으로 유의한 차이를 나타내지 못했다. EPA처리가 부착된 U937세포의 수에 영향을 미치지 못하였다. 결 론: EPA는 U937세포에 영향을 미쳐 혈관내피세포-U937 세포부착을 감소시키지는 못하였다. 따라서 EPA에 의한 혈관내피세포-단핵구 부착 억제 효과는 EPA의 단핵구에 미치는 영향에 의하지는 않는 것으로 생각되나 추후 더 많은 연구가 필요하리라 생각된다. Background : Epidemiological studies have shown correlation between low incidence of coronary heart disease and high consumption of fish products. It has been suggested that this may be due to the high content of polyunsaturated fatty acids of the n-3 fatty acid group in fish oil. In animal studies eicosapentaenoic and (EPA) inhibited attachment of monocytes to the arterial endothlium. Method : Adhesion assay was performed on the endothelial cells of the human umbilical vein with 25, 50, 100, 200 ㎛ EPA-treated U937 cells. The endothelial cells were activated with lipopoysaccharide (LPS). The adhesion assay was repeated with oxidized EPA. EPA was oxidized with CuSO4 and ascorbic acid. Result : Viability of U937 cells were not afected by concentrations up to 200 ㎛ of EPAand oxidized EPA. LPS treatment of endothelium notably increased the number of U937 cells attached to endothelial cells on the adhesion assay. However, treatment of EPA, native or oxidized, to U937 cells did not afect the number of U937 cells attached to LPS activated endothelial cells. Conclusion : EPA treatment, native or oxidized, of U937 cells did not affect U937 cell-endothlial cell adhesion. This suggests that inhibition of monocyte-endothlial cells ◎attachment by EPA is not due to the effects of EPS on monocytes.(Korean Circulatin J 1998;28(4):606-610)
