최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

배무,박상진,류희욱,조경숙,이은영 이화여자대학교 환경문제연구소 1997 이화환경연구 Vol.1 No.-

탈취제로 이용되고 있는 지렁이 분변토로 부터 황화수소를 제거하는 황산화 세균 CP-5를 분리하였다. 이 균주는 운동성이 없고 Gram 음성인 단간균 이었으며, cytochrome oxidase와 catalase test에 양성 반응을 보였다. CP-5 균주는 환원형 황합물을 기질로 하는 배지에서 독립영양적인 생장이 가능하였다. 이 균주는 thiosulfate 에서 tetrathionate를 중간생성물로 하여 최종적으로 sulfate로 산화하고, elemental sulfur를 일단 thiosulfate로 산화한 후, sulfate까지 재산화하는 것으로 사료되었다. 독립영양 배지에 yeast extract 를 첨가하면 균의 생장이 촉진되었다. CP-5 균주 현탁액에 H₂S를 2vvm의 유속으로 주입하면 140ppm까지는 거의 완전하게 제거 가능하였다. 본 연구결과로부터 CP-5 균주는 분변토에서 황화수소를 제거하는 대표적인 탈취균주이며, 황화수소 제거를 위한 생물학적 탈취 공정에 활용 가능하다는 것을 알 수 있었다. A new sulfur-oxidizing bacterium which was capable of degrading hydrogen sulfide was isolated from earthworm casts using deodorant materials. The cell of isolate CP-5 was short rod, gram negative and non-motile, the activities of cytochrome oxidase and catalase were positive. The isolate could autotrophically grow in the basal mineral medium supplemented the reduced sulfur compounds such as thiosulfate and elemental sulfur. This bacterium could oxidize thiosulfate and elemental sulfur to sulfate, and the metabolic intermediates were considered as tetrathionate and thiosulfate, respectively. The removal of hydrogen sulfide by the isolate CP-5 was confirmed, and the CP-5 was regarded as one of microorganisms responsible for degradation of hydrogen sulfide in earthworm casts. The isolate CP-5 can be applied to biodeodorization systems for the improvement of removal efficiency of hydrogen sulfide.

백서에 있어서 가령에 따라 악관절 원판에 가하여지는 기계적 부하의 변화에 따른 악관절 원판의 형태, 탄성섬유 및 세포의 미세구조의 적응등의 변화양상을 관찰하기 위하여, 생후 1일, 7일, 17일, 27일, 55일, 1년 이상군의 백서의 악관절 부위를 적출하여 광학 및 전자현미경으로 관찰하여 다음과 같은 결론을 얻었다. 악관절 원판의 형태는 1일 및 7일군에서는 중앙부의 얇은 부위가 전후방으로 상당히 길게 뻗쳐 있고 전부 및 후부의 최대 풍융부를 향한 경사가 완만하여 하악와 및 하악과두에 적합되지 않는 양상을 보였으나, 17일군부터는 전부 및 후부가 하악와쪽으로 풍융해짐과 동시에 중앙부의 얇은 부위가 전후방으로 좁아지고 전부 및 후부의 최대 풍융부를 향한 경사가 급하여져, 악관절 원판이 하악과두를 감싸는 형태를 취하여 하악와 및 하악과두에 적합되어 가는 양상을 보였다. 가령에 따라 세포밀도는 점점 감소하였으며, 1일 및7일군에서는 세포내 골지장치, 과립성 내형질망, 유리 리보솜 등의 세포질 및 세포간 기질을 활발하게 합성하는 세포 소기관들이 발달 되어 있었으나 세포질내 세사는 발달되어 있지 않았다. 17일, 27일 및 55일에서는 기질합성에 관여하는 세포 소기관의 발달과 아울러 손가락 모양의 세포돌기, 용해소체, 사립체등의 세포간 기질의 개조에 관여하는 세포 소기관이 발달된 세포가 다수 관찰되었으며, 가령에 따라서 세포질내 세사가 점점 축적되어지는 양상을 보였고, 섬유성 물질에 둘러 싸인 chondroid cell들이 증가하였다. 1년이상군에서는 대부분이 세포가 chondroid cell로 구성되어 있었으며 세포질내의 대부분을 세사가 차지하고 세포내 소기관이 거의 발달되지 않는 등 대사 활동이 미약하며 주로 기계적 부하에 적응하기 위한 구조로 이루어져 있었으며 때로는 변성과정에 있는 세포도 다소 관찰되었다. The purpose of this study was to investigate changes in the shape and ultrastructrue of the articular disc of the rat mandibular joint with aging. Mechanical stress applied to the articular disc changes during neonatal, suckling, juvenile, adult and senile stages. Mandibular joints of 6 groups of rats (1-,7-,17-,27-,55-day and over-1-year groups) were removed en bloc and processed for light and electro microscopic study. The changes in the shape of articular disc were examined by light microscope in each group. Structural and ultrastructural changes in the articular disc were examined by light and electron microscope in each group. The results were as follows: In the 1-day and 7-day groups, the articular disc was long and slender in shape and the articular disc was not fitted with the shape of the mandibular fossa and condyle. However, after that time, the anterior and posterior portions of the articular disc were more bulged and the middle portion was shorter and biconcave. Thus the articuler disc was well fitted with the shape of the mandibular fossa and condyle. The cell density decreased wth aging. In the 1-day and 7-day groups, the Golgi apparatus, rough endoplasmic reticulum and free ribosome, which are involved in the synthesis of intracellular and extracellular matrix. were developed. In the 17-day, 27-day and 55-day groups, not only the cell organelles involved in the synthesis of the intracellular and exracellular matrix but also the cell organelles involved in the remodeling of the extracellular matrix(i.e., finger-like cell process, lysosome and mitochondria) were well developed. With advancing age, intracytoplasmic microfilaments were more accumulated and condroid cells increased. In the over-1-year group, the majority of cells of the articular disc were chondroid cells. The majority of cytoplasmic compartment were filled with intracytoplasmic microfilaments and cell organelles were not developed. Therefore, metabolic activites of the cell was markedly reduced and cells contained structures enduring mechanical stress, and cells which were in the process of degeneration were observed occasionally.

To evaluate the degree of bone mineral density according to physical activity, lifestyle in pre- and postmenopausal women. The subjects were 951 premenopausal and 1,167 postmenopausal women who have examined in health promotion center of Yeungnam University Hospital in Daegu city from January, 1999 to Januaty, 2001. The test for bone mineral density. The physical activity and life style were evaluated by questionaire through interview. The results were summarized as follow. 1) The prevalence rates of reduced bone mineral density and osteoporosis in premenopausal women were 23.8% and 1.6%, respectively. However, these values were increased to 46.1% and 28.1% in postmenopausal women. 2) The regular exercise was revealed to have preventive effect for osteoporosis in pre- and postmenopausal women. Among the types of exercise, the most effective exercise was bowling and moderately effective exercise was swimming on prevention of osteoporosis, however, bare hand physical exercise was not significant effect on bone mineral density. 3) The risk for reducing bone mineral density was decreased in women who have higher educational background and income in pre- and postmenopausal. The bone mineral density was highest in white color worker and lowest in blue color worker. 4) The premenopausal women who favor meat were revealed higher bone mineral density than the women who favor vegetable. The women who have drunk none or small amount of alcohol were revealed increased bone mineral density and smoking was a risk factor for osteoporosis. These results suggested that to prevent osteoporosis, the systemized program for promoting anti-osteoporotic factor have to be developed and apply from the thirties whom have maximal bone mineral density.

Rheumatoid arthritis frequently involves the cervical spine and may lead to neurologic impairement. However, direct involvement of CNS structures by inflammatory cells has been reported infrequently. The prevalence of this complication of rheumatoid arthritis is unknown. Inflammatory CNS involvement in rheumatoid arthritis reportedly occurs in the setting of longstanding, active, erosive articular disease and is accompanied by extracranial and extraspinal nodules and vasculitis. This is diagnosed by radiologic finding of CNS nodules or meningeal thickening and by biopsy or autopsy. Treatment with corticosteroid, cytotoxic agent or surgical decompression is helpful. But the majority of patients die within several months of onset of neurologic symptom. Recently, we experienced a case of pachymeningitis caused by rheumatoid arthritis, which resolved repeatedly with azathioprine treatment.
