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.

Objectives : PCR has generally been more sensitive than the conventional microbiological test for the detection of C.trachomatis which has been a leading cause of sexually transmitted disease. The purpose of this study was to evaluate the prevalence of C.trachomatis infection in the patients with pelvic imflammatory disease(PID) and the usefulness of nested PCR as a follow-up test in patiens with C. trachomatis infection after administration of antibiotics. Methods: Cervical swab specimens were obtained from 187 patients with PID and vaginitis attending the Soonchunhyang Chunan Hospital. From the C. trachomatis positive patients, cervical swab specimens were obtained once a week after treatment until PCR tested negative. We performed the nested PCR with Chlamydia-CR kit(Bioneer, Korea.) Results: From 6(5.8%) of 187 cervical swab specimen, C. Trachomatis was detected by nested PCR. These patients were treated with doxycycline and metronidazole for 7 to 14 days. All of 6 C. trachomatis positive patients revealed PCR-negative immediately after the completion of antibiotics treatment. Conclusions: With the above results, the nested PCR is a relatively simple, fast, and practical tool for the detection of C. trachmatis and may be a useful follow-up test for monitoring the treatment effect.

Agrobacterium tumefaciens를 이용한 bialaphos 저항성 형질전환 벼의 개발

이효연,이춘환,김호일,한원동,최지은,김진호,임용표 충남대학교 생물공학연구소 1999 생물공학연구지 Vol.7 No.-

비선택성 제초제인 bialaphos는 고등식물에 있어서 glutamine 합성을 억제하여 식물체를 고사시킨다. Acetyltransferase에 의해 encoding된 bialaphos 저항성 유전자는 세균 Streptomyces hygroscopicus SF1239로부터 cloning된 것을 사용하였다. Bialaphose 저항성 유전자를 Agrobacterium 감염법을 이용하여 국내에서 재배되는 벼(동진)에 도입한 결과 약 30%정도의 형질전환 식물체를 얻을 수 있었다. T_1세대의 17개체는 hygromycin과 bialaphos에 대한 저항성 유전형질이 3 : 1로 분리되었다. 또한 Southern 분석을 실시한 결과 wild type의 식물체에서는 Bar 유전자의 검출을 볼 수 없었으나 형질전환 식물체의 경우 Bar 유전자의 검출이 가능하였다. T_3 세대의 형질전환 식물체와 wild type의 식물체를 포장상태에서 비선택성 제초제인 바스타를 살포하고 3주 후에 관찰한 결과 형질전환 식물체는 외형적으로 아무런 피해를 받지 않고 정상적으로 생장하였으나, wild type의 식물체와 잡초는 모두 고사하였다. 이상의 결과를 종합해보면 hygromycin과 bialaphos 저항성 유전자는 Agrobacterium 감염법을 이용하여 단자엽 식물인 벼에 도입할 수 있다는 것을 보여준 것이며, 또한 bialaphos 저항성 유전자가 식물에 도입됨으로써 비선택성 제초제에 대한 저항성 식물을 개발 할 수 있다는 것을 보여 주었다. The bialaphos is a potent inhibitor of glutamine synthease in higher plants and is used as a non-selective herbicide. We have used the bialaphos resistant gene (Bar) encoding for an acetyltransferase isloated from Streptomyces hygroscopicus SF1293. Callus derived from mature seeds of rice (Oryza sativa L. cv. Dong Jin) were co-cultivated with Agrobacterium tumefacieus EHA101 carring a plasmid pGPTV-HB containing genes for hygromycin resistance (HygR) and Bar. Transgenic plants showing in vitro resistance to 50 mg/L hygromycin and 10 mg/L bialaphos were obtained by using a two-step selection/regeneration procedure. Transformation efficiency of rice was about 30% which was as high as reported in other dicotyledons. Progenies (T_1 generation) derived from primary transformant of 17 lines were segreagated with a 3 resistant:1 sensitive ratio in medium containing hygromycin and bialaphos. Stable integration of Bar gene into chromosomal DNA was proven by Southern blot analysis of genomic DNA isolated from T_2 progenies. Transgenic plants (T_3) grown in the field were resistant to bialaphos (Basta) at a dosage lethal to wild type plants.

Purpose : To make a focal trough (image layer) for an average maxillary dental arch of 6-year-old korean in panoramic radiography. Materials and Methods : Phantom for the maxillary dental arch was designed using intercanine width, intermolar width, tooth size, and interdental spacing to record the data of 6-year-old child. The characteristics of pre-corrected panoramic machine (for adult) was evaluated using the phantom, resolution test pattern for margin of the image layer, and metal ball for the center of the image layer. Panoramic image layer of the child was developed by means of decreasing the speed of film-cassette and positioning the phantom backwards, and then the characteristics of post-corrected panoramic machine (for child) were reevaluated. Results : At post-corrected panoramic image layer, beam projection angles at all interdental areas increased for about 2.6-3.8.., the position of the image layer was shifted toward the rotation center for about 2.5 mm at the deciduous central incisior area. The width of image layer decreased at all areas. Conclusion : Increased beam projection angle will reduce the disadvantage of tooth overlap, and the same form between the center of the image layer and dental arch will improve image resolution.

김상연,한진우,박인우 대한구강악안면방사선학회 2008 Imaging Science in Dentistry Vol.38 No.1

Purpose : This study provides comparative measurements of absorbed and effective doses for newly developed cone beam computed tomography (CT) in comparison with these doses for conventional CT. Materials and Methods : Thermoluminescent dosimeter rods (TLD rod: GR-200, Thermo Fisher Scientific Inc., Waltham, MA, USA) were placed at 25 sites throughout the layers of Male ART Head and Neck Phantom (Radiology Support Devices Inc., Long Beach, USA) for dosimetry. Implagraphy, DCT Pro (Vatech Co., Hwasung, Korea) units, SCT-6800TXL (Shimadzu Corp., Kyoto, Japan), and Cranex 3+ (Soredex Orion Corp., Helsinki, Finland) were used for radiation exposures. Absorption doses were measured with Harshaw 3500TLD reader (Thermo Fisher Scientific Inc., Waltham, MA, USA). Radiation weighted doses and effective doses were measured and calculated by 2005 ICRP tissue weighting factors. Results : Absorbed doses in Rt. submandibular gland were 110.57 mGy for SCT 6800TXL (Implant), 24.56 mGy for SCT 6800TXL (3D), 22.39 mGy for Implagraphy3, 7.19 mGy for DCT Pro, 5.96 mGy for Implagraphy1, 0.70 mGy for Cranex 3+. Effective doses (E_(2005draft)) were 2.551 mSv for SCT 6800TXL (Implant), 1.272 mSv for SCT 6800TXL (3D), 0.598 mSv for Implagraphy3, 0.428 mSv for DCT Pro and 0.146 mSv for Implagraphy1. These are 108.6, 54.1, 25.5, 18.2 and 6.2 times greater than panoramic examination (Cranex 3+) doses (0.023 mSv). Conclusion : Cone beam CT machines recently developed in Korea, showed lower effective doses than conventional CT. Cone beam CT provides a lower dose and cost rnative to conventional CT, promising to revolutionize the practice of oral and maxillofacial radiology.

동일한 시료에 대한 국내 기관간의 STR 분석결과 비교 : STR 유전자좌 분석법의 표준화 설정을 위하여

박종태,신경진,양윤석,우광만,이숭덕,이승환,이정빈,정연보,조승희,한길로,한면수,홍승범 大韓法醫學會 2001 대한법의학회지 Vol.25 No.1

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.
