In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(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 menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. 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 64.5% in 1998.

Child is not little man but rather a father of man. Children are faced to surgical and medical problems reqiring various specialists. Authors analized 1126 pediatric surgical in-patients of Chung-nam National Univ. Hospital from Jan. to Dec. 1988 by departments, age, sex, duration of admission and types of diseases in order to get the information for management of children’s hospital. The results are as follows: 1. Absolute numbers of in-patients by departments are above 200 in general surgery and opthalmology, between 100-199 in plastic surgery, ENT, chest surgery and below 99 in urology and neurosurgery. 2. Male to female ratio as a whole is 1.8:1, male dominant. 3. Duration of admission within 1 week was of 55% as a whole, 87% in ENT, 85% in ophthalmology, 13% in orthopedic surgery. 4. Average duration of admission was 10.8 days as a whole, 4.6 days in ENT, 5.1 in ophthalmology, 29.7 days in orthopedic surgery, and variable by types of diseases. 5. The most frequent disease by departments was hernia in general surgery, fracture in orthopedic surgery, cerebral contusion in neurosurgery, ventricular septal defect in chest surgery, strabismus in ophthalmology, tonsillitis & adenoiditis in ENT.

목적 : 급성하벽심근경색증 환자에서 심전도상 흔히 동반되는 전흉부유도 ST절 하강의 의의를 알아보았다. 방법 : 심근경색후 24시간에서 48시간에 얻은 심전도를 기준으로 52명의 급성하벽심근경색증 환자를 전흉부유도에서 ST절의 하강이 있는 군과 없는 군으로 나누었으며 심도자, 관상동맥조영술, 심초음파도 및 방사성 핵종을 이용한 좌심구혈율 측정 등을 시행하였다. 결과 : 1) 좌심실확장기말압은 전흉부유도에서 ST절의 하강이 있는 경우에서 16.9±5.33mmHg로 없는 경우의 11.0±4.02mmHg보다 유의하게 높았다(p<0.05). 그러나 운동량 및 좌심구혈을은 흥부 유도상 ST절의 하강이 있는 경우 7.6±3.0 METs 및 53.9±9.1%로 없는 경우의 9.1±2.7 METs 및 54.6±9.5%보다 낮았으나 통계적 유의성은 없었다(p=0.180, p=0.823). 2) 관상동맥조영술상 전흉부 ST절의 하강이 동반된 군에서는 유의한 좌전하행지나 좌회선지의 협착이 있는 경우가 60.9% 및 57.9%로 ST절의 하강이 없는 군에서의 34.5% 및 7.7%와 비교해 좌관상동맥에 협착이 동반된 경우가 많았다(p=0.050, p=0.001). 3) 관상동맥조영술상 세 혈관질환의 빈도는 흉부유도상 ST절의 하강을 보인 23예에서 10예로 ST절 하강이 없었던 29예중 2예에 비하여 유의하게 많았고(P=0.007), 단 혈관질환의 빈도는 ST절의 하강을 보인 군에서 23예중 5예로 ST절 하강이 없었던 29예중 17예에 비하여 유의하게 적었다(P=0.002). 두 혈관질환의 경우에는 각각 8예와 10예로 양군간에 유의한 차이가 없었다. 4) 흉부유도상 ST절 하강의 빈도는 단 혈관질환 22예 중 5예에서, 두 혈관질환 18예중 8예, 세 혈관질환 12예 중 10예에서 관찰되어 협착이 있는 관상동맥의 수가 많을수록 ST절의 하강이 나타나는 빈도가 많음을 보였다(p=0.00308). 그러나 흉부유도상 나타난 ST절의 하강을 모두 합하여 구한 ST절 하강의 합은 협착이 있는 관상동맥의 수와 통계적인 유의성이 없었다. 5) 심초음파도상 좌심실 하벽의 벽운동은 ST절 하강을 보인 군에서는 akinesia가 83.3%, hypokinesia가 11.1%, 정상 벽운동이 5.6%로, ST절 하강이 없었던 군에서의 dyskinesia가 3.6%, akinesia가 39.3%, hypokinesia가 25.0%, 정상 벽운동이 32.1%와 비교하여 ST절의 하강이 있는 군에서 유의하게 벽운동의 장애가 빈번함을 보였다(p=0.03891). 그러나 좌심실전벽, 측벽 및 중격부위에서는 유의한 벽운동의 차이가 없었다. 결론 : 급성하벽심근경색증 환자의 전흉부유도에서 ST절의 하강이 동반되는 경우 다혈관 질환의 가능성이 높으며 좌심실확장기말압이 상승되었고 운동능력은 감소되어 있었다. 또한 심초음파도상 좌심실하벽의 벽운동장애도 심하였다. 따라서 전흉부 ST절의 하강을 동반한 급성하벽심근경색증 환자는 전흉부유도에 ST절 하강이 없는 경우보다 예후가 불량할 것으로 생각되며, 보다 적극적인 치료가 필요할 것으로 생각된다. The purpose of this study was to determine the significance of precordial ST segment depression appearing during acute inferior myocardial infarction and to assess the correlation of that with angiographic finding. 52 patients were allocated into two groups based on the existence of precordial ST segment depression : 23 patients with ST segment depression and 29 patients without ST segment depression. The extent of coronary artery disease as well as the prevalence of significant stenosis (≥70%) in left anterior descending artery were more frequent in patients showing precordial ST segment depression than in patients not showing them (p=0.050) and the result were similar in cases of left circumplex artery (p=0.001). On echocrdiographic examination of left ventricular (LV) wall motion, it showed more severely decreased inferior LV wall motion in patients showing precordial ST segment depression than in patients not showing them (p=0.03891) even though the other segment of LV wall motion didn't show the statistical difference between both groups. The other cardiac parameters such as LVEDP, exercise amount (METs) and ejection fraction were tend to showing bad profile in patients with precordial ST segment depression. From the above results, we could deduce that patients with precordial ST segment depression have relatively large infarction or concomitant left coronary artery disease, so they need more caution and intensive theraphy.

마우스의 BCG감염이 R.tsutsugamushi의 증식에 미치는 영향

김인재,전창덕,홍영권,정현택,이복수,장우현,김익상,박석돈 대한감염학회 1993 감염 Vol.25 No.2

It has recently been reported that gamma-inteferon(INF-r) and tumor necrosis factor(TNF) or lipopplysaccharide(LPS) activate macrophages to kill intracellular parasites by means of nitrc oxide (NO). It is now generally accepted that NO is the endothelium-derived relaxing factor, and that it also paticipates in the regulation of the nervous and immune systems. Activated macrophages form NO?? and NO?? from the terminal guanidino nitrogen atoms of L-arginine by the process now known to proceed via the formation of NO. This pathway is inhibited by the L-arginine analog(N?? monomethyl-L-arginine; N??MMA), forms L-citrulline as a co-product and is responsible for the cytotoxic action of macrophages. In this study, the authors found that INF-r and/or LPS induced murine macrophages to kill Rickettsiae tsutsugamushi in vitro and macrophages from BCG-infected mice got the host resistance against R.tsutsugamushi in vitro as well as in vivo. The rickettsicidal effect induced by the combination of INF-r and/or LPS induced mice got the host resistance against R.tsutsugamushi in vitro as well as in vivo. The rickettsicidal effect induced by the combination of INF-r and/or LPS can also be completely inhibited by N??MMA, leading to a dose-dependent inhibition of NO production. These datademonstrate that INF-r and/or LPS as well as BCG-activated macrophages mediate host resistance aganist R.tsutsugamushi infection through NO, which is necessary for the intracellular parasite.

박재훈,주용하,정길웅 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.4

노지에서 비적기재배를 위한 재배연도 및 파종기(4월 15일-조파, 5월 15일-적파, 6월 15일-만파)에 따른 유색콩(대추밤콩, 검정콩1호, 진주1호, 푸른콩)의 생육 및 수량형질의 특성과 유전력을 조사하여 특수콩 품종육성 및 재배 생리적 특성에 대한 기초 자료를 제공하고자 2001년부터 2002년까지 수행한 시험 결과는 다음과 같다. 1. 파종기에 따른 경장은 조파에서 만파로 갈수록 감소하였고, 경직경과 주경절수는 조파와 적파에 비해 만파에서 적었다. 품종에는 경장, 경직경, 주경절수 모두 푸른콩이 가장 크고 굵고 많았다. 2. 분지수와 분지절수는 조파에서 만파로 갈수록 감소하였으며, 분지수는 품종간 차이가 없었고, 분지절수는 푸른콩이 가장 많았다. 3. 100립중은 조파에서 높았으며, 품종 중에는 대추밤콩이 가장 컸고, 진주1호가 가장 작았다. 입중과 10a당 종실수량은 조파에서 만파로 갈수록 감소하였으며, 입중은 검정콩1호가 가장 무거웠고, 10a당 종실수량은 대추밤콩이 가장 많았다. 4. 생육형질의 유전력은 경장이 92%로 가장 높았으며, 수량형질은 100립중이 99%로 가장 높았다. For two years, from 2001 to 2002, this experiment was conducted to investigate growth and yield characters as influenced by different planting dates and cultivation years in order to non-optimal cultivation at field in colored soybean. Varieties used in the experiment were four varieties such as Daechubamkong, Pureunkong, Geomjeongkong 1, and Jinju 1. These varieties were planted on April 15 (early planting), May 15 (optimum planting), and June 15 (late planting), respectively. Stem height rep-resented by different planting dates as early, optimum and late planting had gradually decreased from early to late planting and stem diameter and number of stem nodes were lower in late planting than in early and optimum plantings. Stem height, stem diameter, and number of stem nodes were the tallest, the thickest, and the most Pureunkong of varieties. The number of branches and number of branch nodes had gradually decreased from early to late planting. The number of branches of all varieties was not different and the number of branch nodes was largest Pureunkong of varieties. One hundred seed weight was higher on April 15 as early planting and Daechubamkong was the highest among varieties whereas Jinju 1 was the smallest. Seed weight and seed yield per ten are had gradually decreased from early to late planting. Seed weight was the heaviest Geomjeongkong 1 of varieties and seed yield per ten are was the largest Daechubamkong of varieties. Heritability mean in growth characters tested for two years was the highest in stem height that was 92%. Heritability mean in yield characters was the highest in one hundred seed weight which was 99%.

Streptomyces coelicolor A3(2)의 actinorhodin생성에 미치는 아미노산의 영향

김재헌,피재호,오충훈,최정은 단국대학교 1996 論文集 Vol.30 No.-

We investigated the fatty acid compositions before and after the actinorhodin producrion in Streptomyces coelicolor A3(2). The relatice proportion of 15 and 17 carbon branched-chain fatty acids decreased signifi-cantly during the actinorhodin production. Fatty acid compositions in the mycelia grown in the presence of L-arginine as a sole nitrogen source, which supported actinorhodin production, showed higher relative pro-portion of the i15:0, i17:0 and ai17:0 branched-chain fatty acids. Therefore, it was concluded that common precursors derived from the amino acid were used for actinorhodin and fatty acid biosynthesis.
