Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

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.

대장암종에서 암관련 유전자들의 Promoter Methylation과 암종 발생 및 진행과의 관게에 대한 연구

The colorectal corcinoma is one of the most common malignant tumor in Korea and its carcinogenic mechanism has not been elucidated exactly yet. So far, the most common carcinogenic mechanism has been known to be multiple genetic changes. But, the CpG island hypermethylation has been revealed to be one of the most important carcinogenic mechanism second to the genetic changes. The epigenetic changes characteristically imprint and transfer to the next generation without changes of nucleotide sequences. When the CpG island of promoter or 5'- exon 1 of a specific gene is methylated by DNA methyltrasferases (DNMTs), the gene expression is inhibited. Carcinogenic mechansisms by promoter methylation has been well known, but the progression of the cancer has not been elucidated yet. The molecular researches on the carcinogenic mechanisms largely depended on the tumor tissue containing various components of cell, due to difficulties in harvesting pure homogeneous tumor cells. Promoter methylatonof the cancer related genes as APc, hMLH2, p16, DAP-K and MGMT in 50 cases of sporadic colorectal carcinoma was studied. The pure normal colorectal epithelial cells, and cancer cells from superficial and deep invasive portion were harvested respectively by laser captured microdissection(LCM), and DNA was extracted from them. The promoter methylation was studied by methylation specific poymerase reaction (MSP) after bisulfite modification of the DNA and the expression of the genes by immunohistochemistry. The results suggests that promoter methylation of the cancer related genes are closely related with the colorectal carcinogenesis and it occurrs from early phase of carcinogenesis, progressing constantly to the late stage. And the promoter methylation of normal epithelial cells increased by age. The p15, known to be the genes related to hematologic malignancy, was closely related to the colorectal carcinoma as well.

산림은 많은 양의 탄소를 저장하고 있으며, 산림 탄소 동태는 기후변화에 따라 변화할 것으로 예상된다. 본 연구는 우리나라 산림에서 가장 우점하는 침엽수종과 활엽수종인 소나무림과 참나무림을 대상으로 최근 개발 및 개선된 한국형산림토양탄소모델(Korean ForestSoil Carbon model; KFSC model)을 이용하여 두 가지 기후변화 시나리오(2012년 기온이 2100년까지 유지되는 시나리오(CT), Representative Concentration Pathway(RCP) 8.5 시나리오) 하에서의 산림 탄소 동태를 예측하였다. 5차 국가산림자원조사 자료로부터 소나무림과 굴참나무림 조사구들을 추출한 뒤, 이를 행정구역(9개 도, 7개 특별·광역시) 및 영급(1-5영급, 6영급이상)별로 분류하여 탄소 동태 모의 단위를 설정하였다. 탄소 저장고는 2012년을 기준으로 초기화하였으며, 모의 기간인 2012년부터 2100년까지 모든 교란은 고려하지 않았다. 모의 결과 산림 탄소 저장량은 시간이 경과함에 따라 전반적으로 증가하지만, CT 시나리오에 비하여 RCP 8.5 시나리오 하에서 산림 탄소 저장량이 낮게 나타났다. 소나무림의 탄소 저장량(Tg C)은 2012년에 260.4에서 2100년에는 각각 395.3(CT 시나리오) 및 384.1(RCP 8.5 시나리오)로 증가하였다. 굴 참나무림의 탄소 저장량(Tg C)은 2012년에 124.4에서 2100년에는 219.5(CT 시나리오) 및 204.7(RCP 8.5 시나리오)로 각각 증가하였다. 5차 국가산림자원조사 자료와 비교한 결과, 고사유기물 탄소 저장량의 초기값은 타당한 것으로 나타났다. 모의 기간 동안 소나무림과 굴참나무림의 연간 탄소 흡수율(g C m-2 yr-1)은 CT 시나리오 하에서 각각 71.1과 193.5, RCP8.5 시나리오 하에서 각각 65.8과 164.2로 추정된다. 따라서 우리나라 소나무림과 굴참나무림의 탄소 흡수잠재력은 지구 온난화에 의하여 감소할 것으로 예상된다. 비록 모델의 구조와 파라미터로부터 불확실성이 존재하지만 본 연구는 미래 산림 탄소 동태 파악에 기여할 것으로 기대된다. Forests contain a huge amount of carbon (C) and climate change could affect forest C dynamics. This study was conducted to predict the C dynamics of Pinus densiflora and Quercus variabilis forests, which are the most dominant needleleaf and broadleaf forests in Korea, using the Korean Forest Soil Carbon (KFSC) model under the two climate change scenarios (2012-2100; Constant Temperature (CT) scenario and Representative Concentration Pathway (RCP) 8.5 scenario). To construct simulation unit, the forest land areas for those two species in the 5th National Forest Inventory (NFI) data were sorted by administrative district and stand age class. The C pools were initialized at 2012, and any disturbance was not considered during the simulation period. Although the forest C stocks of two species generally increased over time, the forest C stocks under the RCP 8.5 scenario were less than those stocks under the CT scenario. The C stocks of P. densiflora forests increased from 260.4 Tg C in 2012 to 395.3 (CT scenario) or 384.1 Tg C (RCP 8.5 scenario) in 2100. For Q. variabilis forests, the C stocks increased from 124.4 Tg C in 2012 to 219.5 (CT scenario) or 204.7 (RCP 8.5 scenario) Tg C in 2100. Compared to 5th NFI data, the initial value of C stocks in dead organic matter C pools seemed valid. Accordingly, the annual C sequestration rates of the two species over the simulation period under the RCP 8.5 scenario (65.8 and 164.2 g C m-2 yr-1 for P. densiflora and Q. variabilis) were lower than those values under the CT scenario (71.1 and 193.5 g C m-2 yr-1 for P. densiflora and Q. variabilis). We concluded that the C sequestration potential of P. densiflora and Q. variabilis forests could be decreased by climate change. Although there were uncertainties from parameters and model structure, this study could contribute to elucidating the C dynamics of South Korean forests in future.

본 연구에서는 낙동강을 대상으로 HEC-RAS를 이용하여 보 개방에 따른 하상변동 특성을 분석하였다. 연구 대상 지역은 낙동강 구담교 하류부터 하구둑까지 292.37 km 구간이다. 하상변동 모의를 위하여 1차원 수치해석모델인 HEC-RAS 프로그램을 사용하였으며 2017년도부터 2019년도까지 2가지의 시나리오로 모의를 수행하였다. 시나리오 1은 수문 전면 개방의 조건으로 구축하였으며 시나리오 2는 수문이 설치된 조건으로 모의를 수행하였다. 모의결과, 시나리오 1의 조건에서 합천창녕보 – 창녕함안보 대부분의 구간 (약 40 km)에서 퇴적이 발생한 것을 확인하였다. 또한 낙동강 본류 내의 유사를 포함한 흐름이 보 구조물로 인해 단절되지 않고 연속적으로 하상을 변동시키는 것으로 예측되었다. In this study, the characteristics of bed elevation changes of the Nakdong River when weir gates are opened were analyzed using the Hydrologic Engineering Center-River Analysis System (HEC-RAS). The study area was 292.37 km downstream of the Gudam Bridge to the Nakdong estuary of the Nakdong River. The HEC-RAS program, which is a 1D numerical analysis model, was used to simulate bed elevation changes. Simulations were conducted under two scenarios from 2017 to 2019. Scenarios 1 and 2 were devised under the conditions of a fully opened gate and during gate installation, respectively. Results confirmed that, under the conditions of Scenario 1, deposition occurred in most sections from the Hapcheon-Changnyeong weir to the Changnyeong-Haman weir (a distance of approximately 40 km). In addition, it was predicted that the flow that included sediments in the main stream of the Nakdong River was not interrupted by the weir structure and regularly produced changes in the river bed.

Overexpression of Insulin Degrading Enzyme could Greatly Contribute to Insulin Down-regulation Induced by Short-Term Swimming Exercise

Min Sun Kim,Jun Seo Goo,Ji Eun Kim,So Hee Nam,Sun Il Choi,Hye Ryun Lee,In Sik Hwang,Sun Bo Shim,Seung Wan Jee,Su Hae Lee,Chang Joon Bae,Jung Sik Cho,Jun Yong Cho,Dae Youn Hwang 한국실험동물학회 2011 Laboratory Animal Research Vol.27 No.1

Exercise training is highly correlated with the reduced glucose-stimulated insulin secretion (GSIS), although it enhanced insulin sensitivity, glucose uptake and glucose transporter expression to reduce severity of diabetic symptoms. This study investigated the impact of short-term swimming exercise on insulin regulation in the Goto-Kakizaki (GK) rat as a non-obese model of non-insulin-dependent diabetes mellitus. Wistar (W/S) and GK rats were trained 2 hours daily with the swimming exercise for 4 weeks, and then the changes in the metabolism of insulin and glucose were assessed. Body weight was markedly decreased in the exercised GK rats compare to their non-exercised counterpart, while W/S rats did not show any exercise-related changes. Glucose concentration was not changed by exercise, although impaired glucose tolerance was improved in GK rats 120 min after glucose injection. However, insulin concentration was decreased by swimming exercise as in the decrease of GSIS after running exercise. To identify the other cause for exercise-induced insulin down-regulation, the changes in the levels of key factors involved in insulin production (C-peptide) and clearance (insulin-degrading enzyme; IDE) were measured in W/S and GK rats. The C-peptide level was maintained while IDE expression increased markedly. Therefore, these results showed that insulin down-regulation induced by short-term swimming exercise likely attributes to enhanced insulin clearance via IDE over-expression than by altered insulin production.

Expression of cellular retinoic acid-binding protein-I (CRABP-I) in the cerebrospinal fluid of adult onset moyamoya disease and its association with clinical presentation and postoperative haemodynamic change

신병준,김준범,조영훈,권희,서유성,김연일,나수균,최창욱 대한척추외과학회 1997 대한척추외과학회지 Vol.4 No.2

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.
