The advancement of modern medicine, particularly the application of effective chemotherapeutics and preventive measures, have brought significant changes on the ecological aspect of microbial diseases of man. It was thought worthwhile to study the recent trends and present status of microbial infections in this country. Thus, the relative incidences and their etiological relationships of bacterial species, the pattern of drug sensitivities among the strains, and also the cases diagnosed by the serological methods were studied for the patients of SNU Hospital from January 1963 to December 1967. The results might be summarized as follows; 1. Relationships between bacteria and diseases (1) The species and their relative incidences of bacteria, isolated from various abscess, were α-hemolytic streptococcus 26.6%, Staphyloccus aureus 22.6%, paracolon bacilli 9.9%, coliform bacilli 8.1%, Klebsiella pneumoniae 7.6%, E. coil 6.9%, β-hemolytic streptococcus 5.9%.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Study Design : The authors retrospectively analysed the recovery of clinical symptoms after surgical treatment of lumbar HIVD. Objectives : To investigate the incidence of clinical symptoms, the recovery rate and time after surgical treatment and the difference between L4-5 and L5-S1 lesion. Summary of Literature Review : There are many reports concerning the clinical result of surgical treatment for the HIVD. They usually describe the result as excellent, good, fair and poor. We can't get any information about the recovery rate and recovery time of each clinical symptom from the reports. Materials and Methods : Thirty-eight patients were treated by one level open discectomy from march 1991 to december 1995. The clinical symptoms and signs including SLR, motor deficit, sensory deficit, change of DTR and severity of radiating pain were periodically followed up on the predesigned protocol, Results : In preoperative examination, SLR was positive in 82%, motor deficit in 76%, sensory deficit in 74%, DTR change in 50%, and radiating pain in 100%. The recovery rate of SLR was 96.8%, motor deficit ; 93.6%, sensory deficit ; 78.6%, DTR change ; 21 % and radiating pain ; 84.2%. The average recovery time of SLR was 3.4 months, motor deficit ; 1.9 months, sensory deficit ; 5.3 months, DTR change ; 4.1 months and radiating pain ; 3.2 months. Motor and sensory deficit was more frequent in L4-5 lesion but DTR change was usually noted in L5-S] lesion. The recovery rate and time showed no great difference between the two level. Conclusions : The recovery rate was higher in SLR, motor deficit and radiating pain rather than sensory deficit and DTR change. The recovery time was fastest in radiating pain but variable nature was noted in sensory deficit. Above results may be helpful to explain the prognosis of the lumbar HIVD.

목적: 천장골염의 유무가 척추 관절염의 진단에 중요한데 단순 골반 검사에서 변화가 없는 환자를 대상으로 MRI를 이용하여 천장골염의 조기변화 소견 및 MRI방법에 따른 장점을 비교하고자 하였다. 대상 및 방법: 단순 골반 검사에서 천장골염 유무가 확실하게 구분되지 않은 혈청 음성 척추 관절염 환자 26명을 대상으로 MRI를 시행하고 염증의 주침범위치를 천측과 장측, 관절의 상하로 구분하고, MRI방법에 따른 변화를 비교하였다. 결과: 모든 예에서 조영 증강되는 판누스를 관찰할 수 있었고, Grade I 이하에서는 장골측과 관절하부, 인대성 관절보다 활막성 관절을 더 많이 침범하였다. Grade II 이상에서도 장골측과 관절 하부에 더 많았으나 인대성 관절을 Grade I이하에서보다 더 많이 침범하였다. 관절 주변 지방 침착역시 장골측과 관절 하부에 더 주로 침범하였고 Grade II 이상에서 약간 더 많았다. 관절 주변 골염은 Grade 0에서는 없었고, Grade I에서는 주로 장골측과 관절 하부에서 92%가 양성이었고, Grade II에서는 93%에서, Grade III에서는 64%에서 양성으로, 장골측을 주로 침범하였으나 관절 상하부의 구분은 없었다. 인대성 천장골 관절은 Grade I 이하에서 38%, II 이상에서는 94%에서 침범하였다. 관절 주변 골염과 지방 침착, 그리고 판누스의 관찰에는 MPGR보다 스핀에코 영상이 좋았고, 관절면의 불규칙성 또는 관절강의 확대와 관절 강직여부의 관찰에는 스핀에코에 비해 MPGR 영상이 좋았고, 연골하 경화는 비슷하였다. 천장골염의 정도와 ESR, CRP와의 연관성은 없었다. 걸론: 천장골 관절에서 염증의 시작은 주로 장골 측과 관절의 하부에서 먼저 시작되고, 관절이 진행될수록 장골측에서 천골측까지로 범위가 확대 되었다. MRI방법에 의한 차이로 초기단계에는 스핀에코 영상이 관절염을 확인하는데 도움이 되고 관절면이 불규칙하게 되고 경화가 되어 병이 진행된 상태에서는 MPGR영상이 진단에 더 도움이 되었다. 염증성 배부 동통이 있는 경우 단순 골반 검사에서 이상이 없는 환자인 경우에도 MRI 검사를 시행하여 천장골염의 유무를 확인하는 것이 중요하다. Objective: The early detection of sacroiliitis on X-ray is important to diagnose spondyloarthropathy(SpA). The conventional radiography, bone scan, and computer tomogram have the problems of sensitivity, specificity, and side effects. We examined sacroiliitis using MR imaging in patients who had inflammatory back pain, but no definite changes in conventional radiogrphy. Other radiologic techniques were compared in detection of early sacroillitis. Methods: Twenty six patients with SpA were examined. The MRI findings of both sacroiliac joints were evaluated in every patients, such as pannus, periarticular osteitis and fat accumulation, subchondral sclerosis, and joint space changes(irregularity, ankylosis). Also we analyzed the changes of sacroiliac joints in sacroiliitis. Results: The predominant sites of involvement were upper aspect and iliac surface of sacroiliac joint in subchondral sclerosis, lower and iliac in pannus, periarticular fat accumulation, and iliac in periarticular osteitis. The MPGR images were superior to spin echo images in evaluation of joint space changes(irregularity, and ankylosis). Conclusions: Sacroiliitis is initiated in iliac side and lower portion of sacroiliac joints. MRI can detect early changes of sacroiliitis in patients with no conventional radiographic changes. MRI seems to be needed in patients with inflammatory back pain.

To study the effects of herbicide on the biochemical components of human the rats were grouped in 4 such as A ; administered 4 ppm BPMC alone, B ; 1% ginseng extract alone, and C ; mixed BPMC and 1% ginseng extract every other day. And it obtained following results. 1. Addecting a biochemical changes on the BPMC administered, it was GOT, GPT, ALP, total bilirubin, BUN, and uric acid. 2. No affecting a biochemical changes on the BPMC administered, it was total protein. albumin, and A/G ratio. 3. Group C, mixed administration of BPMC and 1% ginseng extract every other day, shown no significant biochemical changes. 4. Group B, administration of 1% ginseng extract alone shown as almost same as control group. From these above results it was suggested that ginseng extract was protected and controlled against abnormal biochemical changes resulting from BPMC administration.

AR 모델 및 LSQ 기반 변류기 2차 전류 복원 기법

張洙榮(Soo-Young Chang),李東圭(Dong-Gyu Lee),姜相熙(Sang-Hee Kang) 대한전기학회 2006 전기학회논문지A Vol.55 No.6

The current flowing though a power line is measured by a current transformer (CT). Since a CT is a kind of transformer, saturation of magnetic flux in the core may occur when a large primary current flows. This saturation makes the secondary current of a CT distorted and causes problems in the protection point of view. Because of the current distortion, a protection relay cannot collect the correct information showing how the primary power system changed. Consequently, the current distortion may cause the mal-operation or operation time delay of protective relay. In this paper, an algorithm based on AR model and LSQ is proposed to compensate the saturated CT secondary currents. Various test results indicate that the proposed algorithm can accurately compensate a severely distorted secondary current and is not affected by remanence.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

말단비대증 환자에서의 수술전 Octreotide 투여 효과

박경수,김현규,조보연,이홍규,고창순,민헌기,김성연,고경수,이석인,한대희,최길수,정희원,김현집 대한내분비학회 1993 Endocrinology and metabolism Vol.8 No.1

Seven patients with previously untreated acromegaly and invasive pituitary macroadenomas were treated with the long-acting somatostatin analog, octreotide (San- dostatin*, Sandoz) for 3~6 months, before transsphenoidal pituitary adenomectomy. Preoperatively, treatment with octreotide for 3 months reduced the pituitary tumor size by 55~60% in 2 patients, 20~39% in 3 patients and little in the remaining 2 patients. Six patients were treated for another 3 monts, but the size of the pituiary tumor showed no further remarkable changes. Mean basal serum GH concentration fell from 251.6(53.0~470.0) ng/ml to 80.1(9.5~308.0) ng/ml after 3~6months treatment with octreotide. Postopercentrationn of one patient whose pituitary tumor size decreased 65% fell into the normal range. Thus, preoperative administration of octreotide induced shrinkage of GH-producing pituitary rumors in some patients and might have favorable effects on the remission rate in the treated patients.

Biochemical Adaptation of Pinus pumila on Low Temperature in Mt. Seorak, Korea

Kim Chan-Soo,Han Sim-Hee,Lee Wi-Young,Lee Jae-Cheon,Park Young-Ki,Oh Chang-Young 한국자원식물학회 2005 Plant Resources Vol.8 No.3

We tested the hypothesis that alpine plants have special physiological and biochemical mechanisms in addition to their structural adaptation in order to survive under extreme conditions. The photosynthetic organs of Pinus pumila were used to examine the seasonal changes in sugar concentration, antioxidative enzyme, and lipid peroxidation. The concentrations of sucrose, glucose, fructose and reducing sugar were the highest in the leaves in April. But sugar contents in buds and inner barks did not respond sensitively on temperature change. Meanwhile superoxide dismutase (SOD) activity responded sensitively on the change of temperature and SOD in all tissues maintained high activity in April. Meanwhile anthocyanin content increased rapidly in June but the increase of anthocyanin content was not enough to prevent their tissues from the damage by the exposure of high temperature or other stress. In conclusion, under low temperature condition, P. pumila increased the concentration of soluble sugars and SOD activity in their tissues in order to overcome extreme environmental condition. But in summer, these stress defense system against high temperature might be disturbed slightly. This results in the increase of malondialdehyde (MDA) contents in three tissues by lipid peroxidation.
