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.

12-O-Tetradecanoylphorbol-13-Acetate에 의한 HL-60 세포 분화유도중 Vimentin 유전자 전사조절에 대한 AP-1의 역할

임규,김진희,권도원,김승민,이명선,윤경아,손미영,박종일,윤완희,황병두 충남대학교 생물공학연구소 1999 생물공학연구지 Vol.7 No.-

Purpose: To gain insight on the role of AP-1 in transcriptional regulation of vimentin gene during differentiation of HL-60 cells by 12-O-tetradecanoylphorbol-13-acetate (TPA), the levels of vimentin mRNA and AP-1 have been investigated with Northern blot hybridization and DNA mobility shift assay. Materials and Methods: HL-60 cells were grown in RPMI 1640 medium supplemented with 10% heat-inactivated fetal calf serum and antibiotics in a humidified 5% CO_2 at 37℃. Total RNA was prepared by a modification of the method of Karlinsey et al. Northern blot hybridization was performed by the method of Virca et al. EcoRI fragment of pVIM-GEM was used as probe for vimentin mRNA. DNA mobility shift assay was performed by the method of Lim et al. End labeled DNA probe(Upper strand, 5'-CGCTTGATGAGTCAGCCG- 3') for AP-1 binding activity was mixed with nuclear extracts in a 20 μl reaction volume containing 300 mM KCI, 60 mM HEPES, pH 7.9, 25 mM MgCI_2, 1 mM EDTA, 1 mM DTT, 60% glycerol, and 2 ㎍ of poly[dI-dC]. Results: TPA increased vimentin mRNA levels, with maximal stimulation reached at 24 hr. The level of vimentin mRNA was induced in proportion to the concentration of TPA. TPA-induced vimentin mRNA was almost reduced by actinomycin-D pretreatment. TPA-induced stimulation of vimentin gene was completely reduced by staurosporin pretreatment. In DNA mobility shift assay, AP-1 newly appeared at 24 hr during TPA-induced differentiation and was almost not detected after the pretreatment of staurosporin. Conclusions: These results suggest that the induction of vimentin mRNA during TPA-dependent differentiation in HL-60 cells may be mediated by protein kinases C signal transduction and AP-1 is important to transcriptional regulation.

Meige 증후군은 안검경련과 구-하악부의 근긴장이상을 특징적으로 보이는 신경학적 임상증후군이다. 발병원인은 아직 불분명하나 아세틸콜린과 도파민의 신경활성과다(excess neuronal activity)가 원인으로 여겨지고 있으며, 치료로는 향도파민성약물과 항콜린성약물, 그리고 보튤리듐독소 주사가 이용되고 있다. 그러나 증상양상이 다양하며 심리적 영향을 받으므로 전환장애 혹은 불안장애 등의 정신과적 문제로 오진되는 경우가 있다. 저자들은 49세 여자로 초기에 전환장애로 진단되었으나 Meige 증후군임이 밝혀져 성공적으로 치료되었던 환자 1례를 경험하여 문헌고찰과 함께 보고한다. A Meige's syndrome is a rare neurological syndrome characterized by blepharospam and oro-mandibular dystonia. Its pathophysiology is not clearly determined yet, but the hypothesis of dopaminergic and cholinergic hyperactivity is most widely accepted. Anticholinergic drugs, antidopaminergic drugs and botulism toxin injection are currently used for the treatment of Meige's syndrome. The Meige's syndrome could be misdiagnosed as a psychiatric disorder such as conversion disorder or anxiety disorder, because clinical features of the Meige's syndrome are very variable and affected by psychological factors. The authors experienced one case of a 49-year-old female patient who was initially misdiagnosed as conversion disorder but confirmed later as Meige's syndrome, and then successfully treated.

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

7β-Hydroxycholesterol이 사람 백혈암에 대한 세포 독성 효과

임희경,현진원 제주대학교 생명과학기술혁신센터 2002 제주생명과학연구 Vol.5 No.-

The cytotoxic activity of 7β-hydroxycholesterol (7β-OHC) has been evaluated using various leukemia cell lines by MTT test. Among the tested cell lines, 7β-OHC showed to be more cytotoxic to THP-1, human monocytic leukemia cell line. IC50 value of 7β-OHC on THP-1 was 10μM. Kinetic of on THP-1 showed that growth of THP-1 began to decrease at 36 h after treatment 7β-OHC. 7β-OHC induced apoptosis shown by DNA fragmentation by gel electrophoresis. 7β-OHC induced apoptosis through down-regulation of Bcl-2 expression. Taken together, these results suggested that treatment with 7β-OHC inhibits the proliferation of THP-1 cells through apoptosis.

Pb(Sn_½Sb_½)O₃-PbTiO₃-PbZrO₃계 압전 세라믹의 필터로서의 응용

임진호,조상희 경북대학교 공과대학 1987 工大硏究誌 Vol.16 No.-

The effect of the size of sintered body on the resonant characteristic of the Pb(Sn_½Sb_½)O_3-PbTiO_3-PbZrO_3 ceramics was investigated. The attenuation characteristics of ring-dot type and ladder type filter were also investigated. As the sintered body are small, the resonant characteristic (f_γ, f_α) and the center frequency are increased. The big difference between the ring-dot type and ladder type filter was the sharpness of bandwidth and the movement of center frequency. As the poling field increased, the K_p and bandwidth were also increased.

This study examined, as the one way of using zeolite, the about the removal of ammonia nitrogen and phosphorus that cause the eutrophication occurred the adjoining seas.4A type zeolite was used as an adsorbent to remve NH_4-N, PO_4^3-P ion in the artificial seawater. Zeolite is more required than in the fiesh water, under the same conditions, in order to remove NH_4-N in the sea water. The lower the thickness of NH_4-N is in the early stage, the more Freundlich type equation the value of 1./n increases. In case of PO_4^3-P indicated that the removal efficiency was relatively independent of PO_4^3-P concentration. Freundlich parameter 1/n has the value nuder 2. So it shows that absorption is made with relatively ease.
