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.

Objective : The aim of this study was to investigate the neuroprotection effect of estrogen on brain atrophy following cerebral infarction. Method : All animals in this study were classified into 4 groups; ovariectomy group (OVXgroup), cerebral infarction group (INF group), combination ovariectomy and cerebral infarction group ( OVX + INF group), and naturally intact group for control data (NOR group ). Cerebral infarction was made by Chen's method with some modification. Ovariectomy was performed by Wayforth's method. Experimental data for each group was collected at 15days, 1 month, 3 months, and 6 months after starting observation. Serum 17β-estradiol(E2) was determined by radioimmunoassay. Brain volume was measured and calculated with image analysis. Each brain was sliced at intervals of 2mm in chamber after 30 min of freezing in refregerater. Cerebral volume was obtained by sum of volume of each slice level, which was mean area × 2mm. Results : Cerebral ischemia was fou8nd to decrease the serum concentration of 17β-estradiol and to inhibit the physiologically conpensatary function of the ovariectomized rats. Also we found that deprivation of estrogen have resulted in more severe cerebral atrophy followed by cerebral infarction. Conclusion : It is suggested that estrogen has a neuroprotection effect on cerebral atrophy following cerebral infarction.(J Korean Oriental Med 2000;21(4):9-15)

악안면 기형과 부정 교합의 성공적인 교정 치료를 위하여 안모의 3차원적인 평가가 필수적이지만 교정의사는 주로 측모두부방사선사진에 기초한 진단 및 치료계획에 익숙하다. 이는 정모두부방사선사진에 관한 계측치, 악골의 폭경 성장에 관한 지식과 임상적 의의에 대하여 관심이 부족한 때문으로 생각된다. 본 연구에서는 골격성 I 급 부정교합으로 진단된 6세에서 16세 사이의 남자 130명과 여자 171명을 대상으로 정모두부방사선사진 상의 두개골 및 상하악골의 폭경을 계측하여, 연령과 경추골 발육지표(CVMI)에 따른 변화 양상을 알아보았다. 다항 회귀모형(polynominal regression models)과 변수선택법(method of variable selection)을 이용하여 적합한 회귀모형(regresslon model)을 각 성별에서 선택하고 이를 이용하여 연령에 따른 각 계측치의 평균 및 개별 계측치(individual measurement)의 70% 신뢰구간(confidence interval)을 추정하여 그래프로 작성하였으며, 다음과 같은 결과를 얻었다. 1.모든 폭경 계측치는 나이 또는 CVMI의 증가에 따라 점차 증가하였으며,6세부터 16세까지의 총변화량은 상악골 폭경보다는 하악골 폭경이 그리고 여자보다는 남자에서 더 많은 경향을 나타내었다. 2.Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio는 연령과 CVMI에 따른 남녀간의 유의차가 없었다. 3.회귀모형을 이용하여 나이에 따른 남녀 계측치의 평균 및 신뢰구간을 70%로 추정하여 상악골폭경,하악골 폭경, Mx-Mn difference, Mx/Mn ratio에 대한 그래프를 얻었다. 4.한국인의 상하악골 폭경은 성장기 동안 서양인에 비하여 큰 경향을 나타내었다. 본 연구의 결과를 성장기 부정교합 환자의 폭경 성장 평가와 폭경 부조화의 진단에 이용한다면 치아 석고모형 만을 이용하는 한계를 적절히 보완할 수 있다고 생각된다 Three dimensional analysis of malocclusion and craniofacial deformation is essential for the successful orthodontic treatment. But the orthodontists are not familiar with diagnosis and treatment plane based on lateral cephalometric analysis. Since orthodontists do not posses a sufficient knowledge in standard value of posteroanterior cephalometric analysis and of clinical importance for transverse jaw growth. In this study male(n=130) and female(n=171) aged from 6 to 16 and diagnosed as Class I malocclusion were selected to analysis width of cranium, maxilla and mandible on the posteroanterior cephalogram. The changes as a function of chronologic age and cervical vertebrae maturity index(CVMI) were examined. The proper regression model was selected by sex with polynominal regression models and method of variable selection. Mean of each measurements and 70% confidence interval of individual measurement according to age was assesed and a graphs were made. Results are as follows : 1.All the measurements for the width are gradually inclesed as increase in chronologic age and CVMI. From the total amount of change between age 6 and 16, there is a tendency that mandibular width is broader than maxillary width and the width of male is broader than female. 2.There is no statistically significant sexual difference in Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio according to age and CVMI. 3.Mean of each measurement and 70% confidence interval of individual measurement according to age and sex were assessed and graphs were made for maxillary width, mandibular width, Mx-Mn difference, Mx/Mn ratio. 4.The width of maxilla and mandible in Korean children are broader than Western children during growth period.

There are many causes of trismus. Aetiology can be roughly divided into muscle spasm, mechanical interference, extracapsular ankylosis, intracapsular ankylosis. Trismus caused by mechanical interference between postero-lateral wall of zygoma-maxillary complex and coronoid process following reduction of fractured facial bone is rare. Especially on maxillary bone fracture, when we faced the trismus following removal of intermaxillary fixation, we got used to solve that problem by physical exercise, We obtained good resurts by coronoidectomy on patients with limited mouth opening who were referred from department of plastic surgery, St. Marys' hospital, the Catholic university of Korea. We report our experience with literature review.

Primary aldosteronism is a syndrome characterized by hypertension, hypokalemia, suppressed plasma renin activity, and elevated serum aldosterone levels. Conn first described it 1955 in association with adrenal cortical adenoma(Conn's syndrome). Today, it can be divided into at least six distinctive sub-groups. The diagnosis of primary aldosteronism is usually suspected when the patient presents with poorly controlled hypertension with hypokalemia. The main issues in the evaluation of primary aldosteronism are to differentiate an adenoma from hyperplasia and to localize the adenoma. Basic hormonal studies and computed tomographic(CT) scanning can be used effectively for that differentiation. An adenoma is one of a few potentially curable forms of hypertension, and it is best treated by removing the adrenal tumor. We experienced a case of a typical adrenal adenoma. The patient was a 37-year-old male who had experienced in both his legs over a period of several days a weakness due to hypokalemia. He was diagnosed using basic hormonal studies and adrenal CT scanning. After, he received laparoscopic adrenalectomy and was discharged with improved condition.

Simulated Moving Bed를 이용한 Bupivacaine 키랄분리 : (1) Preparative Chromatography를 이용한 기본조건 결정 (1) Optical Separation Conditions for Preparative Chromatography

Racemate Bupivacaine의 키랄분리를 위한 크로마토그래피의 최적분리조건을 조사하였다. Kromasii^(�) 키랄고정상에서 최적이동상조성 성분은 n-hexane/2-propanol/acetic acid/triethylamine, 99/1/0.3/0.05(vol.%)이였다. 이동상 조성성분인 2-propanol의 부피비가 증가할수록 체류시간과 분리도가 동시에 감소되었다. 이동상 성분 중에서 미량으로 존재하는 triethylamine이 증가할수록 피크의 sharpness가 증가하고 체류시간 역시 감소하였다. 또한, acetic acid가 없으면, 크로마토그래피 광학분할이 불가능하였으며 부피 0.3%에서 분리도가 가장 높음을 확인할 수 있었다. 한편, 키랄의약품의 대량분리방법중의 하나인 SMB(simulated moving bed)크로마토그래피 시스템(직경 1.0cm×10cm×8개 칼럼으로 구성)의 최적분리조건을 전산모사에 의해 구하였으며, 이를 실험으로 확인하였다. 그 결과 switching time 15분, feed의 유량 0.1 ml/min, desorbent 0.86 ml/min, raffinate 0.3 ml/min, extract 0.66 ml/min, recycle 1.0 ml/min일 때 100% 순도의 R-form과 S-form을 얻을 수 있었으며, 실험치와 전산모사치간의 오차는 ??2%이내였다. The chiral separation of racemate Bupivacaine was carried out to find the optimum condition for chromatographic system. The optimum species and composition for mobile phase were n-hexane/2-propanol/acetic acid/triethylamine, 99/1/0.3/0.05(vol.%) in case Kromasil� chiral stationary phase was employed. The retention time and resolution decreased with the increase in the ratio of 2-propanol in the mobile phase. The sharpness of peak and retention time decreased, as the content of triethylamine increased. Without the existence of acetic acid, the chromatographic separation didn't occur, and the resolution was the highest at the acetic acid volume ratio of 0.3%. The optimum condition of SMB (simulated moving bed) was determined by simulation and its results was compared with exprimental data from lab-scale SMB (10 mm 1D×8 ea). Rased on the SMB simulation and experimental results, 100% purity of R and S Bupivacaine were obtained and the error between the calculated and experimental value was within ±2%.
