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.

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.

제주도 연안 해양환경 중에서 유기인계 농약의 잔류

김정호,오윤근,김정배 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.4

제주도 연안의 수산물 생산력 향상을 위해서는 연안 해양환경 보전이 무엇보다 중요하다. 특히 골프장의 농약 오염원이 연안환경과 수산생물에 미치는 영향을 규명할 필요가 있다. 따라서 제주도의 농업 오염물질 중 유기인계 농약에 의한 연안해역의 오염을 규명하고자, 1997년 7월과 8월에 남제주도에 위치한 중문골프장에 인접한 색달동과 대포동 근해 해양환경시료에서 monocrotophos와 EPN 유기인계 농약 잔류를 조사하였다. GC-FPD에 의한 monocrotophos와 EPN의 시료중 최소 검출농도는 동ㆍ식물의 고체시료에서는 0.024ng/g, 0.020ng/g이었다. 또한 해수에서는 각각 0.012ng/mL, 0.010ng/mL이었다. 식물시료인 우뭇가사리와 미역, 동물시료인 소라와 성게에 대한 유기인계 농약의 잔류량 조사 결과 모든 시료에서 monocrotophos와 EPN이 검출되지 않았다. monocrotophos와 EPN은 색달동과 대포동에서의 해수와 저니토에서도 검출되지 않았으며, 이러한 결과는 7월, 8월에서도 동일하였다. 따라서 남제주도 중문골프장 근해 해양 환경 중에서는 monocrotophos와 EPN의 유기인계 농약오염은 없는 것으로 나타났다. To investigate the residue of organophosphorus pesticides such as Monocrotophos[Dimethyl-l -methyl-2-methyl carbamoylvinylphosphate] and EPN[O-ethyl-O-4-nitnophenyl phenylphosphonothioate] in the coatal environmen of Cheju island, samples of sea organism, water and sediment were collected at the Sackdaldong and Daepodong near the Jungmoon golf course in July and Aug. 1997. The qualified detection limit of monocrotophos and EPN by GC-FPD were 0.024 ng/g and 0.020 ng/g in the sea organism, respectively. Neither Monocrotophos nor EPN was detected in seaweed cava(Ecklonia cava), Agar(Gelidium amansii), turban sell (Batillus cornutus) and sea urchin (Anthocidaris Crassispina). They were not detected in seawater and sediment either. These results showed that the coastal area near the Jungmoon golf course in the Cheju island was not polluted by the organophosphorus pesticides such as Monoc개tophos and EPN.

서정호,박윤관,김명현,정용구,정흥섭,서중근,이훈갑,주정화,이기찬 대한신경외과학회 1992 Journal of Korean neurosurgical society Vol.21 No.8

Serial changes in the size of infarcted area induced by MCA occlusion(MCAO) were compared with Neutral Red(NR) and 2,3,5-Triphenyl tetrazolium chloride(TTC) stains. The differences in size of the infarcted area as shown by the 2 stains and its significance were also evaluated. The experimental animals were divided into 7 groups, with each group consisting of rats; these groups were stained at 2,4,6,8,12,24 and 48 hours after MCAO. After MCAO, NR was infused into the femoral vein, after which the brain was removed, the frontal pole of the brain cut into 1.5㎜ sections, and each section photographed. Then, the NR-stained sections were immersed in TTC solution for 45 minutes and photographed. Results showed that the infarcted area progressively increased according to time duration after MCAO(one-way ANOVA, p<0.01). Between 4 and 6 hour groups, the difference of the infarcted area was greater than at any other timed groups, this being statisfically significant(unpaired t-test, p<0.05). After 6 hours, the infarcted area with NR stain became relatively stable. In contrast, however, the infracted area with TTC stain did not stabilize, but continued to increase up to 24 hours. Overall, the infarcted area with NR stain was greater than with TTC stain in all the timed groups(paired t-test, p<0.05). As time progressed, the differences tended to decrease 48 hours post occlusion. In our study, serial changes of the ischemic penumbra area were evaluated by staining the ischemic area simultaneously with Neutral red and TTC stain. The results suggest that the ischemic penumbra area may still persist even after 48 hours post-MCAO.
