Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

The development of in vitro assays has been recommended to screening and test-ing the potential endocrine disruptors (EDs). These assay systems focus only on identifying thethe thyroid hormone (TH) disruptors. The aim of this study was to evaluate a test system to detectTH disruptors using rat pituitary tumor GH3 cells. The test system is based on the TH-dependentincrease in growth rate. As expected, L-3,5,3-triiodothyronine (T3) markedly induced a morphologicalchange in GH 3 cells from flattened fibroblastic types to rounded or spindle-shaped types. T3 stimu-lated GH3 cell growth in a dose-dependent manner with the maximum growth-stimulating effect9 M. In addition, T3 increased the release of growth hor-mone and prolactin into the medium of the GH3 cells culture. Using this assay system, the TH-dis-rupting activities of bisphenol A (BPA) and its related compounds were examined. BPA,dimethylbisphenol A (DMBPA), and TCI-EP significantly enhanced the growth of GH3 cells in therange of 1 × 10-5M to 1 × 10-6M concentrations. In conclusion, this in vitro assay system might bestandardization before it can be used as a broad-based screening tool.

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.

김유진,김동욱,이석,이동건,박윤희,김희제,김태규,민우성,김춘추 대한조혈모세포이식학회 2003 대한조혈모세포이식학회지 Vol.8 No.2

연구배경: 비혈연간 조혈모세포이식은 HLA체계에 대한 이해의 증진과 새로운 검사법의 개발, 그리고 기증자 수의 증가에 힘입어 최근 빠르게 증가하고 있다. 방법: 가톨릭조혈모세포이식센터에서 1995년 10월부터 2001년 12월까지 비혈연간 이식을 받은 138명의 성인 환자를 대상으로 후향적 분석을 하였다. 결과: 질환별로 만성골수성백혈병 66예, 급성림프구성백혈병 23예, 급성골수성백혈병 16예, 재생불량성빈혈 21예, 골수이형성증후군 9예, 비호지킨림프종 2예, 그리고 발작성야간혈색소뇨증이 1예였다. 일차 생차부전은 분석가능한 136예 중 4예(2.9%)에서 발생하였다. Ⅱ도 이상의 급성이식편대숙주병의 발생률은 48.1%였고, 만성이식편대숙주병은 49.5%였다. 재발 이외의 사망원인 중 가장 높은 빈도를 보인 것은 폐렴으로, 독성사망 64예 중 36예(52.3%)에서 관찰 되었다. 만성골수성백혈병의 경우(n=66), 무병생존율, 재발률, 비재발성 사망률이 각각 45.7%, 11.4%, 49.2%였다. 무병생존율은 표준위험군이 고위험군에 비해 통계적으로 유의하게 높았다(50.3% vs 32.0%, p=0.03). 급성림프구성백혈병의 경우(n=23), 무병생존율, 재발률, 비재발성 사망률이 각각 30.0%와 49.4%, 44.8%였던 반면, 급성골수성백혈병에서는(n=16) 28.6%, 39.4%, 52.9%였다. 이들 급성백혈병에서는 표준위험군에 비해 고위험군에서 재발률과 비재발성 사망이 모두 높게 관찰되었다. 중증재생불량성빈혈의 경우(n=21), 무병생존율과 비재발성 사망이 37.3%와 62.7%였다. 결론: 본 연구의 결과 비혈연간 이식은 HLA적합 형제가 없는 혈액질환 환자들에게 유용한 치료법의 하나임을 알 수 있었다. 낮은 병기에서의 조기 이식과 분자생물학적 방법을 사용한 HLA 적합도의 개선이 이식관련 사망을 최소화시켜 비혈연간 이식의 효과를 더욱 확대시킬 수 있을 것으로 생각된다. Background: Unrelated allogeneic stem cell transplantation (U-SCT) is recently on a increasing trend supported by better understanding of HLA system, development of new HLA typing, and increase of donor pool. Methods: We retrospectively analyzed 138 adult patients who underwent U-SCT between October 1995 and December 2001 at Catholic Hematopoietic Stem Cell Transplantation Center. Results: Diagnoses were chronic myeloid leukemia (CML, n=66), acute lymphoblastic leukemia (ALL, n=23), acute myeloid leukemia (AML, n=16), severe aplastic anemia (SAA, n=21), myelodysplastic syndrome (MDS, n=9), non-Hodgkin lymphoma (NHL, n=2), and paroxysmal nocturnal hemoglobinuria (PNH, n=1). Primary engraftment failure was observed in 4 (2.9%) of 136 evaluable patients. Acute GVHD (≥grade II) occurred in 48.1% and chronic GVHD occurred in 49.5%. The most common cause of death other than relapse was pneumonia, which occurred 36 (52.3%) of 64 toxic deaths. In CML, disease-free survival (DFS), relapse rate, and non-relapse mortality (NRM) was 45.7%, 11.4%, and 49.2%. DFS of the standard-risk group (SR) was significantly better than that of high- risk group (HR) (50.3% vs 32.0%, P=0.03). In ALL, DFS, relapse rate, and NRM was 30.0%, 49.4%, and 44.8%, whereas corresponding figures for AML were 28.6%, 39.4%, and 52.9%. NRM and relapse rate were higher in HR compared to SR in acute leukemia. In SAA, DFS and NRM was 37.3% and 62.7%. Conclusion: We concluded that U-SCT is a feasible therapeutic option for patients lacking a HLA-matched sibling donor. Transplantation at earlier phase of disease with more accurate HLA matching by molecular typing can minimize treatment-related toxicity and could extend the benefit of U-SCT.

Breeding of Tetraploid in Codonopsis lanceolata (Sieb. et Zucc.) Trautvetter by Colchicine Treatment

Kim,Ik-Hwan,Kim,Hag-Hyun,Hong,Eui-Yon,Yun,Jong-Sun,Yun,Tae,Hwang,Ju-Kwang,Lee,Cheol-Hee 한국자원식물학회 2003 Plant Resources Vol.6 No.3

Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Codonopsis lanceolata. Three tetraploid plants of C. lanceolata were produced from seeds which absorbed 0.1 % colchicine solution for 12 hours, and 0.5% colchicine solution for 1 and 6 hours from seedlings, respectively. But tetraploid was not produced from shoot tips treated by colchicine solution. Compared to diploid, tetraploid plants had larger stomata, but less number of stomata. Fresh weight of tetraploid plants was 1.4∼3.6 times heavier than diploid plants.

The current study evaluates the capacity of eugenol to regulate immediate allergic reaction by control of histamine release. Administrations of eugenol (1 M/kg. i.p.) at 60 min before and 5.10 min after the compound 48/80 treatment (8 mg/kg.i.p.) were shown the mortality rates as 0.44.4. and 77.8%. respectively. A 60 min before administered group revealed a singificant inhibition of serum his-tamine release compared with those of 5 and 10 min after the compound 48/80 injection. Eugenol (6-48mM) was also showed a dose-dependent activity on the compound 48/80-induced histamine release from the highly purified population of Alcian Blue-positive peritoneal mast cells. These results indicate that in vitro treatment with exogenous eugenol inhibited the active response of mast cell populations and modulated its characteristics.

Premature ovarian failure (POF) is a condition in which the ovarian functions of hormone production and oocyte development become impaired before the typical age for menopause. POF and early menopause are present in a broad spectrum of gonad dysgenesis, from a complete cessation of ovarian function to an intermittent follicle maturation failure. Actually POF has been identified as a genetic entity (especially chromosome X), but data on genetic factors of premature menopause are limited. Until now, several cases revealed that inactivation of X chromosomes has an effect on ages of premature menopause and females with balanced or unbalanced X-autosome translocations can have several reproductive problems. On the other hand, there have been a few data that was caused by autosome-autosome translocation can lead. Therefore we report a relevant case of POF with translocation between chromosomes 1 and 4. She had her first menstrual period at the age of 12, and after 7 years she stopped menstruation. Chromosomal analysis showed 46, XX, t (1;4) (p22.3;q31.3). While evaluating this rare case, we could review various causes (especially genetic factors) of POF. To remind clinicians about this disease, we report a case of POF caused by autosomeautosome translocation with a literature review. (J Menopausal Med 2015;21:112-114)

金載勳,崔美善,李喜佑,金泰俊,김연욱,南泰鉉 대한금속재료학회 2002 대한금속·재료학회지 Vol.40 No.7

Phase transformation behavior and shape memory characteristics of Ti-Ni-Cu alloy ribbons fabricated by melt spinning have been investigated by means of differential scanning calorimetry, X-ray diffraction, optical microscopy and thermal cycling tests under constant load. With increasing linear velocity and decreasing ejection pressure, transformation start temperatures of ribbons decreased and stability of the B19 martensite was lowered, comparing to those of alloys fabricated by conventional casting since the cooling rate increased. Only after heat treating ribbons at temperatures higher than 873 K where recrystallization occurred, the B19 martensite was observed in Ti-40Ni-10Cu alloy ribbons. Transformation elongation and hysteresis associated with the B2-B19 transformation in Ti-Ni-Cu alloy ribbons decreased with increasing Cu-content, which was attributed to the decrease in lattice deformations. Transformation elongations of ribbons were larger than those of alloys made by casting, which was closely related to a texture developed in ribbons.

Ventricular septal defect remains an infrequent but devastating complication of acute MI. Approximately 1∼3% of cases of acute myocardial infarction are complicated by ventricular septal rupture in the prethrombolytic era and the incidence has decreased to 0.2% with reperfusion therapy. This mechanical complication usually occurs within the first 10 to 14 days when necrotic tissue is most abundant and the collateral coronary circulation is not well developed. This lesion is generally associated with complete coronary obstruction rather than severe stenosis. Rupture of the ventricular septum is a severe mechanical complication of acute myocardial infarction, usually resulting in death unless surgical repair is performed. The bad prognosis of this event within the first 2 weeks indicates the need for early surgical rapair. This complication is more frequent after the first acute myocardial infarction in the elderly and secondary to a transmural myocardial infarction. We report two cases of ventricular septal rupture after acute myocardial infarction.
