Zoysia japonica Steud. is a warm-season lawn grass popular in Korea and elsewhere. They are cultivated in many places such as river banks, roadside, and play grounds. However, there still is a disadvantage of frequent mowing, and the grass grows poorly under the chilly conditions. To develop a grass variety that circumvents these drawbacks, we cloned the chitininducible gibberellins-responsive1 gene (CIGR1) from zoysiagrass. The full length of the ZjCIGR1 (Zj; Zoysia japonica Steud.) gene was obtained by 5′/3′ RACE PCR and the phylogenetic tree showed that it belonged to the CIGR1-subgroup in the PAT1-group of GRAS protein family. Expression of the ZjCIGR1 in wild-type plants was confirmed in roots, meristems, leaves, and flowers, especially high in the flowers. The transgenic zoysiagrass was confirmed by PCR using gene-specific primers, phosphinothricin-acetyl-transferase (PAT) strip test, and Southern blot analysis. ZjCIGR1-overexpressing plants acquired tolerance to cold stress displaying morphological phenotypes characteristic of stress resistance. In addition, in the transformants, expression of the ZjCIGR1 as well as cold-regulated (COR) gene was increased compared to the wild-type plants under cold stress condition. These results suggest that ZjCIGR1 gene is an important candidate for regulating cold stress resistance.

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.

홍승철,한진희,정종현,김소양,허균,이성필 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.1

저자들은 Creutzfeldt-Jacob병 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 약 4개월에 걸친 비교적 짧은 기간 동안 중증의 인지 기능 장애와 시각 장애, 보행장애와 하지의 약화, 불수의적 운동 등과 함께 섬망상태에까지 이르게 되어 본원 정신과에 입원하게 되었다. 정신상태 검사상, 반응시간의 지체, 언어장애와 보속증, 시간에 대한 지남력 장애, 주의 집중력 장애, 단기 및 장기 기억 장애, 추상적 사고능력 장애 등의 소견을 보였고, 이러한 증상들은 입원후 치료에도 불구하고 빠르게 악화되었다. 뇌파검사상 지속적인 다발초점성 서파가 모든 전극에서, 특히 우측 전두부에서 현저하게 나타나는 소견을 보였고, 병리조직학적 검사상 대뇌 피질에 신경손실을 동반한 해면화와 신경교 증식증을 나타냈다. 이상의 소견들은 모두 CJD의 진단에 합당하였다. We report a case of Creutzfeldt-Jacob disease and review the relevant literatures. This 56-year-old male patient was admitted to our hospital with a history of rapidly progressing cognitive dysfunction, visual disturbance, gait disturbance, weakness, involuntary movement of lower extremities, and the symptoms of delirium. On mental status examination, he showed psychomotor retardation, speech disturbance, perseveration, disorientation, impairment of short-term and long-term memory, and inability of abstract thinking. He had a rapid downhill course, along with shakiness of trunk, rigidity of the limbs, myoclonus, confusion, and finally, inability to speak or move on the bedside. On electroencephalogram(EEG), continuous multifocal show delta activities were found in all leads, especially in the right frontal areas. Brain biopsy showed, spongiosis with neuronal loss and gliosis noted at the cerebral cortex. These findings were compatible with Creutzfeldt-Jacob disease.

홍진표,김윤,배재남,정유진,강영호,양병국,김용익,김병후,이철,조맹제 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.2

국내 중증 만성정신질환자 수를 추정하기 위하여 일 농촌 및 대도시 지역의 지역의료보험 및 의료보호 대상자 중 1993년 1년간 의료기관에서 정신증 상병(ICD-9 code 상 290-299) 및 알콜 남용/중독, 성격장애 및 정신박약 진단하에 치료를 받은 적이 있는 사람에 대해 설문조사를 실시하였다. 연구자들이 개발한 진단도구를 이용하여 진단을 평가하고, Strauss-Carpenter scale 등을 이용하여 기능 장애를 평가하고 유병기간 등을 조사하였다. 결과를 요약하면 다음과 같다. 1) 진단평가상 정신분열병군(61.1%)이 가장 많았으며, 정동장애군(23.7%), 알콜장애군(11.2%), 기질성 정신장애군(4.0%)의 순서이었다. 2) 직업활동정도는 진단군별로 차이가 많았다. 지난 1년간 직업활동이 6개월 미만이거나 전혀 없는 환자 비율이 정신분열병군은 67.2%, 알콜장애군 52.0%, 정동장애20.8%의 순으로 정신분열병군이 가장 불량하였다. 3) 사회활동도 진단군별로 차이가 많아서 지난 1년간 의도적, 사회활동이 없는 비율이 정신분열병군이 가장 높았고(72.3%), 알콜장애군(32.0%), 정동장애군(20.7%)의 순이었다. 4) 국내 의료보험 및 사회복지시설 이용 자료 등을 토대로 본 조사 결과를 적용한 결과 국내중증 만성 정신질환자의 수는 약 8만 7천명으로 추산되었다. Objectives: The purpose of this study was to estimate the number of serious and persistent mentally ill patients in Korea. Methods : Study populations were recruited from medical insurance data of two district areas ; one rural and the other urban areas. Subject were all mentally ill who had ever visited any hospital in 1993 and were diagnosed as having psychosis, personality disorder and drug abuse. We conducted a home visiting survey applying semi-structured diagnostic interview, assessing the level of social adjustment with Strauss-Carpenter Scale, and past psychiatric history by the trained researchers, in October and November,1994. Results : According to diagnostic assessment schizophrenic patients constituted the major portion(61.1%) of study subjects. The distribution of occupational functions and social contacts was variable according to diagnosis. Most schizophrenic patients were unemployed or worked less than 6 months in the previous year(67.2%), and showed poor social contact(72.3%). But affective disorder patients were relatively independent in job maintenance and social relationship. Alcoholic patients lay between those of schizophrenic and affective disorder groups. It was estimated that about 87,000 adult Koreans were suffering from chronic mental disorders which seriously interfere with their daily life. Conclusions : Serious and persistent mentally ill patients were common in Korea. Community support program should be provided for them.

고어텍스를 이용한 비성형 5례

진홍률,양상권,최영석 충북대학교 의과대학 충북대학교 의학연구소 1999 忠北醫大學術誌 Vol.9 No.2

비성형수술에 삽입하는 사용물로는 자가연골이 가장 이상적이지만 필요한 만큼의 충분한 양을 얻기가 힘들고, 수술시간이 길어지며, 흡수가 일어날 수 있다는 단점이 있다. 이러한 단점을 극복할 수 있는 이종이식물 중에서 고어텍스는 최근에 개발되어 사용이 점차 증가하고 있는 추세이지만 아직까지 고어텍스의 임상적 효용성에 대한 보고는 드물다. 저자들은 고어텍스를 5명의 융비술 환자에서 사용하였는데 3명은 연골과 같이, 2명은 고어텍스 단독으로 사용하였다. 이 중 1명에서 감염이 발생하여 고어텍스를 제거하고 늑연골을 이용하여 융비술을 다시 시행하였고 나머지 4명은 모두 만족스러운 결과를 얻었다. 평균 20개월의 추적관찰에서 이식물의 이동이나 탈출, 피부의 손상 등의 큰 부작용이 없어 고어텍스가 비성형, 특히 융비술에 유용하다고 판단되어 관련문헌 고찰과 함께 보고하는 바이다. Though autogenous cartilage remains the ideal graft material in nasal surgery, situations exist where an alternative or an additional grafting material is needed. Gore-Tex is one of most recently developed alloplastic material and has been widely used for rhinoplasty. But there are few reports about the clinical efficacy of this material in rhinoplasty. The authors used Gore-Tex as a nasal implant in 5 cases of augmentation rhinoplasty. In three patients, the Gore-Tex was used with septal or conchal cartilages because the cartilages were not enough for the needed augmentation. In one patient, the implant was removed due to postoperative infection and subsequent augmentation was done with autogenous rib catilage after infection control. During average 20 months of follow-up, complications such as absorption, mobilization, or extrusion of the implant and thinning of the nasal skin were not found. All patients were satisfied with the surgical results. From these results, Gore-Tex can be considered as an effective material in augmentation rhinoplasty when autogenous material is not available or is not sufficient for the proper augmentation.

양진홍,박규남,최승필,김영민,김세경 대한응급의학회 2001 대한응급의학회지 Vol.12 No.2

Background: There are approximately 2,400 drowning deaths reported every year in Korea, but there are few good reports about submerged patients visiting the emergency room, so this study was designed to investigate the clinical characteristics and outcomes of submerged patients treated at an emergency medical center near the Han river. Methods: A retrospective review of 123 cases of submerged patients admitted to our emergency medical center over a 5 year period from 1996 to 2000 was conducted. Results: Among the 123 submerged patients, there were 66 males and 57 females, and their mean age was 33.18. The common cause of submersions was a suicide attempt, followed by lack of attention, unknown etiology, and water sports such as swimming. Most of the patients were transported to ER by 119 ambulance. In-hospital CPR was performed on 27(22%) cases. At initial ECG rhythm of these cases, asystole was noted if 25 patients; VF and pulseless electrical activity, respectively, were noted in two others. Prehospital CPR had been performed on all in-hospital CPR cases except 2. Prolonged ROSC after succesful CPR was noted in 13 cases, The mean duration of CPR was 26 minutes. Five patients survived after CPR. Their neurologic outcomes were assessed on CPC(cerebral performance category). Three patients were categorized in CPC1, the other two patients were categorized in CPC3 and CPC4. Conclusion: Submerged patient's visits to emergency medical center near the Han river were most frequent in summer for suicide purposes. Drowned patients were more hypothermic than other cardiac arrest cases, and resulted in better outcome even with prolonged arrest time, if they were given appropriate prehospital CPR and aggreissive in-hospital resuscitation.
