        The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

        This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.

        우리나라 사람면역결핍바이러스(Human Immunodeficiency Virus) 감염환자에서 발병한 악성종양

        최평균,송진수,조재현,김성한,박경화,방지환,박완범,김홍빈,김동완,김태유,허대석,오명돈,김남중,최강원 대한감염학회 2006 감염과 화학요법 Vol.38 No.6

        Background : Since highly active antiretroviral therapy has lengthened the life span of individuals infected with human immunodeficiency virus (HIV), the importance of malignancy associated with HIV has been increased. The relative frequencies of malignancies in HIV infected patients may vary in different race and region. The aim of this study is to determine the prevalence and characteristics of malignancies in patients with HIV infection in South Korea. Materials and Methods : To identify HIV patients with malignancy, we reviewed the electronic database of pathological reports for all HIV-infected patients seen from January 1986 to December 2005 at the Seoul National University Hospital. We retrospectively reviewed the medical records of them. Results : Among 850 patients infected with HIV, 33 episodes of malignant diseases were diagnosed in 32 patients (3.76%). Thirty were males, and median age was 46 years (range 29-70). At the time of the diagnosis of malignancy, median CD4^(+) lymphocytes count was 100/uL (range 5-620) and in 27 (82%) patients, CD4^(+) lymphocytes count were less than 200/uL. For 13 patients (40%), malignancy was initial presentation of HIV infection. Excluding patients initially diagnosed as malignancy, median follow-up duration from the first visit to diagnosis of malignancy was 36 months (range 3-96). Non-Hodgkin's lymphoma was the most frequent malignancy (13 patients), followed by Kaposi's sarcoma (7), Hodgkin‘s disease (3), acute myeloid leukemia (1), and other solid cancer (9) including one case of anal cancer associated with human papillomavirus. Among 13 patients with non- Hodgkin's lymphoma, 4(31%) achieved the complete remission after chemotherapy and/or radiation therapy, and had been followed without evidence of recurrence. Conclusion : Malignancy was diagnosed in 3.76% of patients infected with HIV. Non-Hodgkin‘s lymphoma is the most prevalent malignancy in HIV patients in South Korea. 목적 : 효과적인 항레트로바이러스 다제요법이 도입됨에 따라, HIV 감염환자들의 수명이 증가되었고, 이에 따라 HIV 감염환자에서 악성종양의 중요성 또한 증가하고 있다. 본 연구의 목적은 우리나라 HIV 감염환자에서 악성종양의 유병률과 호발하는 악성종양의 특성을 밝히는 것이다. 재료 및 방법 : 1986년부터 2005년까지 서울대학교병원에서 치료를 받은 HIV 감염환자의 의무기록을 후향적으로 분석하였고, 병리학적 검사 결과를 검토하여 악성종양이 진단된 환자들을 대상으로 연구를 시행하였다. 결과 : 총 850명의 환자 중, 32명(3.76%)에서 33예의 악성종양이 진단되어, 악성종양의 발병률은 1,000인년 당13.0명(95% 신뢰구간: 8.6∼17.4명)이었다. 그 중 남자는 30명이었고, 악성종양 진단 당시 연령의 중간값은 46 (29-70)세이었다. 악성종양 진단받을 당시, CD4 림프구 수의 중간값은 lOO/uL (5-620 uL) 이었고, CD4 림프구수가 200/ uL 미만인 환자가 27명(82%)이었다. 악성종양에 대한 검사 도중에 HIV 감염사실이 밝혀진 환자가 13명(40%)이었다. HIV를 진단 받은 후 악성종양이 발병한 환자들에서, HIV 진단 후 악성종양의 발병까지는 평균 36개월(3-96개월)이 걸렸다. 13명의 HIV 감염 환자에서 진단된 비호지킨림프종이 가장 흔한 악성종양이었고, 이외에 카포시육종이 7명, 호지킨병이 3명, HPV와 연관된 항문암이 1명의 HIV 환자에서 진단되었다. 그 밖에 급성백혈병, 방광암, 췌장장, 폐암, 진행성위암, 갑상선암, 간세포암, 후두암이 각각 1예씩 진단되었다. 비호지킨림프종이 진단된13명 환자 중, 4명(31%)은 항암치료 및 방사선치료를 받아 완전관해가 되었고, 현재 재발의 증거 없이 외래에서 경과 관찰 중이다. 결론 : 우리나라 HIV 감염환자에서 악성종양의 유병률은 3.76%이었고, 비호지킨림프종이 가장 흔한 악성종양이었다.

        상부위장관 출혈 원인의 변화 양상

        김태년,도병수,김현정,이삼범,정문관 大韓應急醫學會 1999 대한응급의학회지 Vol.10 No.2

        Upper gastrointestinal(UGI) bleeding was critical disease that was commonly found in emergency department and needed more early diagnosis and rapid treatment for decreasing mortality and morbidity. It's causes and frequencies were affected by many factors, but the majorities were caused by peptic ulcers and esophageal-gastric varices. With development of economy and medical services, new drugs and endoscopic interventions, the treatment of patients with UGI bleeding was more improved. So I would like to evaluate the change of causes and frequencies of UGI bleeding and the associated clinical findings. A total of 1,546 patients presented with UGI bleeding in emergency department of Yeungnam university hospital during the five years from Jan. 1991 to Dec. 1995 were clinically reviewed by chart and compared with previous seven years report from Jan. 1984 to Dec. 1990 in the same hospital. The ratio of male to female was 6.1:1 and slightly increased in comparison with previous seven years. The incidences in 6th and 5th decades were highest(54.4%)as like as previous seven years. Age distribution of duodenal ulcer bleeding, Mallory-Weiss tear and acute gastric mucosal lesion were developed in lower decades than the others. The causes of UGI bleeding were caused by esophageal varix(45.4%), peptic ulcer(38.8%), Mallory-Weiss tear(4.3%), gastric cancer(3.8%), other(3.1%), acute gastric mucosal lesion(2.7%), undetermined causes(1.8%) in descending order of frequencies. The proportion of esophageal varices was increased from 36.6% to 45.4%, but that of peptic ulcer was relatively decreased from 47.6% to 38.8%. And the annual distribution of varices was increased, however the annual distribution of peptic ulcers was increased. Although the ranking of annual distribution of gastric ulcers and duodenal ulcers were not changed compared to previous study and the frequency of gastric ulcers was increased since 1992, but additional follow-up was needed. Seasonal variations were found that upper gastrointestinal bleeding was increased in fall and peptic ulcer bleeding was increased significantly in summer and fall, however, varix bleeding was less frequent in summer time as like as previous seven years. Emergency endoscopic examination was performed within 6 hours for 54.5%, 24 hours for 90.8% and this results were to be like previous results, 57.5% and 90.7 respectively. Findings of emergency endoscopic examination were active bleeding focus(21.2%), blood clot(7.9%), exposed vessels(13.3%), flat blood spot(6.4%) and lesion without evidence of bleeding(51.3%). Endoscopic findings of active bleeding were easily seen when examination was perfomed within 24 hours. Blood transfusion was performed in 67.3% with average 2.1 units. When the causes of bleeding were due to varix and marginal ulcer, more amounts of blood were transfused than the others. In previous seven years, blood transfusions were performed in 71.2% with average 5 units and more amounts of blood were transfused in gastric cancer and varix bleeding.

        진동에 의한 혈관 내 폐 보조장치의 산소전달 특성

        김기범,권대규,이삼철,김성종,정인수,오인혁,김기주,변윤섭,정경락 한국화학공학회 2004 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.42 No.2

        본 연구는 급성호흡부전환자를 치료하기 위하여 사용되고 있는 혈관 내 폐 보조장치의 기체전달을 향상시키기 위하여 중공사막에 진동기법을 사용하여 기체전달을 향상시키고자 시도하였다. 그리고 혈관 내 폐 보조장치를 정맥에 삽입하기 전, 혈관 내 폐 보조장치의 설계조건을 실험적 모델을 통하여 기체전달을 예측할 수 있는 예측식을 만들고자 하였다. 실험결과, 본 연구에서는 진동기법이 기체전달을 향상시키는데 효과적임을 확인할 수 있었다. 뿐만 아니라, 충진율과 가징 주파수의 함수관계를 이용하여 기체전달을 예측 할 수 있었다. 실험에 의하여 얻어진 결과는 예측식에 의하여 얻어진 결과와 유사한 결과를 얻었다. 그러므로 본 연구에서는 충진율과 가진 주파수의 함수를 이용하여 VIVLAD의 기체전달을 예측할 수 있었다. In this paper, we tried to improve gas exchange of the vibrating intravascular lung assist device(VIVLAD) using vibrating method in the hollow fiber membrane, for the patients suffering from acute respiratory distress syndrome(ARDS). And we tried to formularize prediction equations to make a prediction about gas transfer for designing intravenous artificial lung assist device, and designed modules under various conditions were studied through an experimental modeling before inserted the artificial lung assist device into as venous. As a result, we are convinced that vibration method is very useful for the has transfer increasing. Also, we can estimate the gas transfer as a function of the packing density and excited frequencies. The gas transfer obtained from the experiment was similar to that from the prediction equation, confirming the usefulness prediction equation. Therefore, we can estimate the gas transfer of the VIVLAD as a function of the packing density and excited frequencies.

        악성종양 적출술과 방사선치료후 형성된 구강내의 관통창의 폐쇄 : 증례보고

        김종배,유재하,김태우,김승범 大韓顎顔面成形再建外科學會 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.6

        The orocutaneous perforated wound can be occurred after the so-called "pull-through" operation involving the resection of intraoral tumor, radical neck dissection and reconstruction, owing to inaccurate coaptation of soft tissue and wound infection. The postoperative orocutaneous through and through open wound is healed & closed by homeostatic wound contraction if soft tissue drainage was well established, which seldom is interfered with local or systemic abnormalities. But, the fistula may not be closed owing to the accumulated damage of radiation theraphy, because the therapy induce the 3-H(hypoxic, hypocellular, hypovascular) condition in future. Because the hyperbaric oxygen therapy has the improved effects of the 3-H condition, such as , fibroblast proliferation, neovascularization and increased phagocytosis of leukocytes, the therapy is useful for the control of radiation-induced ischemic orocutaneous wound infection. If the refractory orocutaneous fistula is remained in spite of the infection control by use of the continuous wound drainage and hyperbaric oxygen therapy, the fistula should be closed with the two-flap technique. Its operative procedure is suturing the minor flap to line oral floor and then transposing the larger flap to provide skin coverage. The authors treated the male patients with the refractory orocutaneous fistula by these methods, such as, continuous drainage, hyperbaric oxygen therapy and two flap technique. The prognosis of these therpies was favorable during 10years.

        개선된 사람 혈장중 세파클러 농도 정량법을 이용한 세파클러 캡슐의 생체이용률 측정

        김태완,송옥경,한선영,Cao, Qing-Ri,박미진,강성화,신관석,Cui, Jing-Hao,이범진 한국약제학회 2005 Journal of Pharmaceutical Investigation Vol.35 No.2

        After establishing improved HPLC analytical method ofcefaclor in human plasma samples, a bioavailability study of cefaclor capsules was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). The standard calibration curve using an HPLC with UV detector was constructed in a range of 0.0324--16 μg/m1. The 6% perchloric acid instead of 6% trichloroacetic acid was used to precipitate plasma protein. The HPLC chromatograms were precisely and accurately resolved when spiked with human plasma spiked with cefaclor and cephalexin (internal standard). Twenty healthy male Korean volunteers received two commercial cefaclor capsules, Neocef ' capsule (Jinyang Pharm. Co., Ltd) or Ceclor" capsule {Lilly Korea. Co., Ltd.) at the 250 mg cefaclor in a 2 x 2 crossover study. There was a one-week washout period between the doses. Plasma concentrations of cefaclor were monitored for 8 hours after oral drug administration. AUC, the area under the plasma concentration-time curve from time zero to 8 hr (13 points), was calculated by the linear trapezoidal rule method. C,,,a" (maximum plasma drug concentration) and Tmax (time to reach Cma,) were compiled from the plasma concentration-time data. Analysis of variance was carried out using logarithmically transformed AUC, and Cmax. No significant sequence effect was found for all of the bioavailability parameters indicating that the cross-over design was properly performed. The 90% confidence intervals of the AUC, ratio and the Cmax ratio for Neocer/Ceclor" were 0.9049 S S < 1.0304 and 0.9776 5 S 1.226, respectively. These values were within the acceptable bioequivalence intervals of 0.80-1.25. Thus, our study demonstrated the bioequivalence of Neocef"/Ceclor" with respect to the extent of absorption.
