한강 중하류의 남조류 및 환경요인의 연간변화 (2000 ${\sim}$ 2003)를 파악하기 위하여, 2000년 4월부터 2003년 10월까지 4년간 성수대교에서 성산대교까지 총 5개 지점을 선정하여, 수계의 기초환경요인 및 식물플랑크톤 현존량 변화를 조사하였다. 조사기간 동안, 남조류의 현존량은 점차적으로 감소하여 장기간 강우가 가장 많았던 2003년에는 거의 관찰되지 않았으며, 총 식물플랑크톤 현존량에 대한 남조류의 기여도는 약 10%범위내였다. 이러한 현상은 매년 강우집중기 동안 팔당댐으로부터 많은 방류수가 유입됨으로서 수온감소는 물론 광량감소, 영양염류 희석 등에 의한 남조류의 성장이 제한된 것으로판단되며, 동일시기에 다른 조류 (녹조, 규조 등)의 높은 성장으로 엽록소 a와 식물플랑크톤 현존량이 뚜렷하게 증가하였다. 따라서 한강 하류의 고온기 동안 남조류 성장은 잦은 강우와 방류에 의해 제한을 받지만 규조나 녹조와 같은 다른 조류들의 높은 성장으로 대치되는 천이현상을 보였으며, 기후영향을 크게 받는 전형적인 하천생태계의 특성을 나타냈다. For 4 years (2000 ${\sim}$ 2003), annual fluctuations of standing crops of cyanobacteria and physicochemical factors were examined at five sites from Bridge of Seungsoo to Bridge of Seungsan in the lower part of Han River. The cyanobacterial abundance (ND to 4,167 cells $mL^{-1}$) was strongly decreased during the heavy rains in every year. During the similar periods in 2003, cyanobacteria hardly observed, and comprised below of 10 percentage of total phytoplankton. In the period of little cyanobacteria, some green algae and diatom dominated the phytoplankton community, while the concentration of chlorophyll a has not largely change. These results indicate that heavy frequent precipitation strongly limited the growth of cyanobacteria, and lead an algal succession by the appearance of new algal groups.

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.

손석한,노경선,허묘연,정현옥,이소희,김세주 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.4

연구목적 : 일반 청소년의 문제행동(내재화 문제, 외현화 문제)을 평가하고, 그들을 정상 집단과 문제행동 집단으로 나누어 집단간에 부모 각각의 양육행동이 어떠한 차이를 보이는지 알아보고자 한다. 방 법 : 서울 소재의 일반 고등학교 학생 792명을 대상으로 부모 양육행동 척도와 K-YSR을 실시하여 청소년이 지각하는 부모의 양육행동과 청소년의 문제행동을 평가하였다. 부모의 양육행동과 청소년의 문제행동과의 상관관계를 분석하였다. 학생들이 보고한 각 문제행동을 상/하위 25% tile을 기준으로 정상 집단과 문제행동 집단으로 나누어 부모의 양육행도의 차이를 분석하였다. 결 과 : 다음과 같다. 1) 부모의 애정, 합리적 설명, 감독의 긍정적인 양육행동은 대부분의 청소년 문제행동들과 유의한 부적 상관을 보였다. 반면에 학대, 과잉간섭, 과잉기대, 방임, 비일관성이 부정적인 양육행동은 문제행동들과 유의한 정적 상관이 있었다. 2)내재화 문제를 보이는 청소년들은 정상 집단에 비해 부모로부터 학대, 과잉간섭, 과잉기대, 방임, 비일관성의 양육행동을 유의하게 더 많이 받았고, 반면에 애정을 유의하게 더 적게 받았다고 지각하고 있었다. 외현화문제를 보이는 청소년들은 정상집단의 청소년들에 비해 부모로부터 학대, 과잉간섭, 과잉기대, 방임, 비일관성의 양육행동을 유의하게 더 많이 받았고, 반면에 감독을 유의하게 더 적게 받았다고 지각하고 있었다. 3) 내재화 및 외현화 문제를 모두 보이는 집단이 내재화 문제만 보이는 집단과 외현화 문제만 보이는 집단에 비해서 양쪽 부모로부터 유의하게 더 많은 과잉간섭을 받을 것으로 지각하고 있었다. 또한, 내재화-외현화 집단과 내재화 집단은 외현화 집단에 비해서 어머니로부터 유의하게 더 적은 애정과 더 많은 방임을 받고 있고, 아버지로부터 유의하게 더 많은 학대를 받은 것으로 지각하고 있었다. 결 론 : 이상의 결과로 미루어 볼 때, 청소녕이 지각한 부모의 학대, 과잉간섭, 과잉기대, 방임, 비일관성의 양육행동은 청소년의 내재화 및 외현화 문제 모두와 유의한 연관이 있고, 반면에 부모의 애정, 감독, 합리적 설명의 양육행동은 다양한 청소년기 문제행동을 줄일 수 있음을 시사하고 있다. Objectives : The purpose of this study is to evaluate the problem behaviors of adolescents and to discriminate between parenting behaviors of problem behavior groups and those of non-problem behavior group. Methods : The subjects of this study were 792 high school students in Seoul. We administered 'parenting behavior Inventory' and Korean version of Youth Self-Report(K-YSR) to the subjects in order to evaluate the parenting behaviors perceived by adolescents and the problem behaviors of adolescents. We analzed the relationship between parenting behaviors and problem behaviors. We classified the subjects into problem behavior groups(internalizing group, externalizing group, internalizing-externalizing group) and a non-problem behavior(normal) group. We studied the differences of parenting behaviors among the groups. Results : The results are as follows. 1) There were significant negative correlations between the positive parenting behaviors such as affection, reasoning, and monitoring and the problem behaviors of adolescents. By contrast, there were significant positive correlations between the negative parenting behaviors such as physical abuse, intrusiveness, over-expectation, neglect, and inconsistency and the problem behaviors of adolescents. 2) Adolescents of the internalizing group perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Meanwhile, they perceived significantly less affection than normal adolescents. Adolescents of the externalizing group also perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Also, they perceived significantly less monitoring than normal adolescents. 3) Adolescents of the internalizing-externalizing group perceived significantly more intrusiveness from both parents than those of either the internalizing or the externalizing groups. Adolescents of the internalizing-externalizing group perceived significantly less affection and more neglect from their mothers than those of the internalizing of the externalizing groups. In addition, adolescents of the internalizing-externalizing group perceived significantly more physical abuse from their fathers than those of the internalizing or the externalizing groups. Conclusion : Parenting behaviors such as abuse, intrusiveness, over-expectation, neglect, and inconsistency are associated with both internalizing and externalizing problems. In contrast, our results suggest that parenting behaviors such as affection, monitoring, and reasoning might decrease the various problem behaviors of adolescents.

This study was performed to investigate the chewing movements in subjects with unilateral chewing habit. 42 patients with temporomandibular disorders and 44 dental students without any signs and symptoms of the temporomandibular disorders were selected as the patients group and the control group, respectively. BioEGN of the Biopak (BioResearch Inc. USA) was used to record chewing movements pattern as to chewing velocity, range of movements and symmetry of the path to midline. The data were analyzed by the preferred chewing side and/or the affected side by SAS/stat program. The results obtained were as follows : 1. In control group, right side chewing subjects showed more deflected path to preferred chewing side than left side chewing subjects have done. But in patients group, there was no significant difference in chewing pattern between the two subjects. 2. In unilaterally affected patients, right side affected patients showed slight difference between the movements to both sides, but left side affected patients showed significant deflection to the affected side. 3. There were some difference in preferred chewing side movement pattern between the patients group and the control group in right chewing subjects whereas no difference was seen between the two groups in left chewing subjects. 4. There was no difference in chewing velocity and range of movements between right and left side movement in all cases compared by preferred chewing side or affected side.

mecA 양성 메티실린 내성 포도구균의 mec 조절유전자에 대한 분자역학적 연구 및 다양성 분석

우희연,이남용,맹성호,한승훈,인경수,김상욱,성승용,김익상,최명식 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.3

목적 : 병원 감염과 지역 감염의 원인균으로서의 중요성이 증가되고 있는 MRSA와 MRCNS의 메티실린 내성 관련 유전자에 대해 분자역학적인 조사를 시행하고 mec 조절유전자의 다양성을 분석하여 분자유전학적 연구와 감염 관리에 기본적 자료를 제공하고자 연구를 시행하였다. 방법 : 본 연구에서는 국내 동일 대학병원에서 분리된 mecA 양성 MRSA 78균주와 MRCNS 36균주를 대상으로 항균제 감수성 검사와 중합효소연쇄반응을 시행하여 표현형과 유전형의 분포를 알아보고 내성 정도와 유전형의 상관성을 분석하였다. 결론 : 최소억제농도를 측정하여 oxacillin 감수성 양상을 알아본 결과 총 90개의 MRSA 임상검체 중 3균주에서 감수성을 보였고, MRCNS 36균주는 모두 내성을 보였으며, 고도 내성을 보이는 균주일수록 다제내성을 보이고 있었다. 중합효소연쇄반응으로 mecA 유전자 유무를 분석하여 mecA 양성을 보인 MRSA 78균주와 MSCNS 36균주 만을 대상으로 mec 조절유전자에 대한 중합효소연쇄반응을 시행하여 유전형의 분포를 조사하였다. 그 결과 MRSA와 MRCNS 모두에서 mecA-Pr-mecA-mecR1-mecI형, mecA-Pr-mecA-mecR1형과 mecA-Pr-mecA-mecR-1의 5′말단형의 3가지 유전형이 공통적으로 관찰되었는데, 이외에 MRSA에서는 mecA-mecR1형, mecA-mecR1의 5′말단형이, MRCNS에서는 mecA-Pr-mecA형과 mecA형이 추가로 분리되었다. 유전형의 분포를 연도별로 분석한 결과 연도별로 우세한 유전형이 서로 다른 것을 알 수 있었다. 유전형과 내성 정도의 상관성을 분석한 결과, mecA-Pr-mecA-mecR1을 보유한 MRSA의 경우 mecA 억제유전자로 생각되는 mecI 유전자 유무에 관계없이 모두 고도 내성을 나타내어 mecI의 유무는 내성 정도와는 일정한 관련이 없었으나, MRSA와 MRCNS 모두에서 mecI와 동시에 mecR1의 3′말단이 결혼된 유전형이 저도 및 중등도 내성을 보이는 균주에서 유의하게 많이 관찰되어 mecI가 결손된 균주에서는 mecR1의 3′말단부위의 유무가 내성 정도의 결정에 중요한 역할을 할 것으로 생각하였다. 결론 : 국내에서 분리되는 메티실린 내성 포도구균의 유전형의 분포가 국외 분리주와 차이를 보이는 것으로 관찰되었다. 또한 기존의 보고와는 달리 메티실린 내성 정도와 유전형 사이에 유의한 연관성이 있는 것으로 관찰되어 mec조절유전자가 내성 발현 뿐만 아니라 내성 정도의 결정에 중요한 역할을 하는 것으로 관찰되었다. MRSA가 중요한 감염균임에도 불구하고 아직까지 MRSA의 내성기전에 대해 확실하게 규명되지 않아 치료가 더욱 어려워지고 있는 실정이므로 이에 대한 더욱 종합적인 연구와 동시에 발생과 확산을 막기 위한 노력이 필요할 것으로 생각된다. Background : High prevalence of methicillin resistance has been noticed in staphylococci which also have been recognized as important nosocomial and multi-drug resistant pathogens. In this study, we investigated the distribution of mec regulator genes and the presence of the mutation in mecIgene to reveal the resistance mechanism at molecular level. Methods : The isolates included 90 clinical isolates of MRSA, 36 MRCNS of which methicillin resistance were determined by disk diffusion test and isolated in a single hospital during 1996-1999. We performed microdilution MIC test for oxacillin resistance and Kirby-Bauer test for other antibiotics. Genotypes of mecA positive (determined by PCR) isolates (78 MRSA, 36 MRCNS) were investigated by PCR amplification of mec regulator genes such as 3' end and 5' end of mecR1. mecI, and Pr-mecA. Results : In MIC assay, all MRSA strains except 3 strains and all MRCNS strains showed oxacillin resistance. The level of resistance correlated to the multi-drug resistance. Seven genotypes were observed in mecA positive MRSA and MRCNS. Differences of predominant genotypes among years isolated and among species were observed. Deletions of the 3' end of mecR1 and the mecI were more frequently observed in the low- and borderline-level resistant MRSA and MRCNS (P(0.05). So the important role of 3' end of mecRI in determining resistance level was suggested. Conclusion : This study demonstrated that genomic distribution of methicillin-resistant staphylococci isolated in Korea was different from that of strains isolated in other countries. And important role of mec regulator genes for expression of methicillin resistance was suggested.
