Background : In recent years, gonorrhea has been panedemic and remains one of the most commom 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 VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

고리원자력발전소 주변의 식생에 대한 식물사회학적 조사를 실시하였으며, 순1차생산력과 식물현존량을 추정하였다. 또한 상관에 의한 현존식생도 및 녹지자연도를 작성하였다. 종조성표에 의한 식물군락은 소나무군락, 곰솔군락, 서어나무-굴참나무군락, 아까시나무군락으로 구분되었다. 소나무군락은 아교목층(평균식피율 35%)이 빈약하였으며, 서어나무-굴참나무군락은 비교적 안정된 계층구조를 이루고 있었다. 전체적으로 교목층에서 소나무, 곰솔, 아교목층에서 사방오리, 졸참나무, 저목층에서 졸참나무, 사스레피나무, 초본층에서 산거울, 주름조개풀 등의 피복지수가 높았다. 삼림토양의 pH는 4.30~4.85, 유기물함량은 6.04~9.40%의 범위였다. 현존식생도에 의한 분포비율은 곰솔군락(31.4%)이 가장 높았으며, 평균녹지자연도는 5.4였다. Montreal model에 의한 순1차생산력은 1555.2g/㎡/yr, 식물현존량은 단위면적당16,982,21ton/k㎡으로 추정되었다. The forest vegetation and estimation of phytomass and net primary production in the vicinity of Kori Atomic Power Plant was analyzed on the basis of the phytosociological data. Depending on physiognomy, actual vegetation map and the degree of green naturality(DGN) was also drawn in the of 1:50,000. According to Z-M method, the forest vegetation was classified into four communities, which include Pinus densiflora, Pinus thunbergii, Carpinus laxiflora-Quercus variabilis, and Robinia pseudo-acacia communities. The Pinus densiflora community was most poorly covered in tree-2 layer. The Carpinus laxiflora-Quercus variabilis community was relatively stable in the stratum structure. It was generally shown that Pinus densiflora and Pinus thunbergii in tree-1 layer, Alnus firma and Quercus serrata in tree-2 layer, Quercus serrata and Eurya japonica in shrub layer, and Carex humilis and Oplismenus undulatifolius in herb layer had high coverage index. The pHs and contents of organic matter of the forest soil collected in each sites was in the range of 4.30 to 4.85 and 6.04% to 9.40% in average in the communities. The Pinus thunbergii community showed the highest distribution rate(31.4%) in the actual vegetation map. The average DGN was approximately 5.4. Net primary production and phytomass per unit area obtained by Montreal model were estimated to be 1555.2g/㎡/yr and 16,982.21ton/k㎡, respectively.

The pandemic influenza (H1N1 2009) virus, after being introduced in Korea in April, 2009, spread rapidly nationwide in mid-2009. This study was conducted to characterize trend in age distribution of visitors to Flu-clinics during the pandemic. Demographic, clinical and laboratory data of visitors to flu clinic from Week 36 to 52 (August 30 to December 26) of 2009 were retrieved and collected from electronic databases at 9 hospitals. Visitors 0-6, 7-12, 13-18, 19-29, 30-64, and 65 years or more of age were classified into group I to VI, respectively. A total of 107,467 visitors were seen at Flu-clinics for a 17-week study period. Of those, 32,485 were laboratory-confirmed. Antivirals were prescribed for 62,533 visitors. Numbers of visits, prescriptions of antivirals, and laboratory-confirmed cases of the pandemic influenza (H1N1 2009) peaked at Week 44. A large number of visits by group II and III were followed by those of group I and V, especially around the peak. Numbers of visits by group VI were lowest in all hospitals. In some hospitals, higher number of visits lasted longer in children than in adults while vice versa in other hospitals depending on the location. In summary, the pandemic influenza (H1N1 2009) was presumed to peak in late October and involved majorly children and students in Korea. Unique age distribution of visitors to flu clinic was observed in some hospitals.

Background/Aims: Data regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in nonagenarians are very limited. The aim of the present study was to evaluate the temporal trends and in-hospital outcomes of primary PCI in nonagenarian STEMI patients. Methods: We retrospectively reviewed data from the Korea Acute Myocardial Infarction Registry (KAMIR) from November 2005 to January 2008, and from the Korea Working Group on Myocardial Infarction (KorMI) from February 2008 to May 2010. Results: During this period, the proportion of nonagenarians among STEMI patients more than doubled (0.59% in KAMIR vs. 1.35% in KorMI), and the rate of use of primary PCI also increased (from 62.5% in KAMIR to 81.0% in KorMI). We identified 84 eligible study patients for which the overall in-hospital mortality rate was 21.4% (25.0% in KAMIR vs. 20.3% in KorMI, p = 0.919). Multivariate analysis identified two independent predictors of in-hospital mortality, namely a final Thrombolysis in Myocardial Infarction (TIMI) flow < 3 (odds ratio [OR], 13.7; 95% confidence interval [CI], 3.2 to 59.0; p < 0.001) and cardiogenic shock during hospitalization (OR, 6.7; 95% CI, 1.5 to 30.3; p = 0.013). Conclusions: The number of nonagenarian STEMI patients who have undergone primary PCI has increased. Although a final TIMI flow < 3 and cardiogenic shock are independent predictors of in-hospital mortality, primary PCI can be performed with a high success rate and an acceptable in-hospital mortality rate.

This study investigated mean airborne CO concention of 15 workplaces, suspected of CO exposure and conducted self-reported questionnaire completion and indirect COHb concentration measure using Micro II Smokerlyzer to healthy 702 adult subjects from 1999 May to 1999 September in order to find a relation of CO exposure and occupational factors, socioeconomic factors, and health related behaviors and confirm the related conditions in the screening test for CO exposure. The results of this study were summarized as follows : 1. In the CO exposed and non exposed group, COHb concentrations of the smokers were 2.55±0.96% and 2.21±0.97% and that got a statistically significant difference, There were not statistically significant differences in the age and total smoking index. Passed times after the last smoking, Working time/day, and working duration were statistically significant difference (p〈0.05). 2. In the CO exposed and non exposed group, COHb concentrations of non-smoking group were 0.94±0.35% and 0.68±0.47% and that got a statistically significant difference. There were not statistically significant differences in the age and working duration but Working time/day was a statistically significant difference(p〈0.05). 3. In the CO exposed group, r-square of multiple regression of the smokers was 38.5 % and passed time after the last smoking, working time/day, and job category were statistically significant differences (p〈0.05). And r-square in the CO non-exposed group was 38.3 % and age, passed time after the last smoking, and total smoking index were statistically significant difference. 4. In the CO exposed group, r-square of multiple repression of the non-smokers was 66.3% and job category and airborne CO concentration were statistically significant differences(p〈0.05). But r-square of non-smokers in the CO non-exposed group was 1.0% and there was not a statistically significant difference(p〈0.05). 5. In the smokers of CO exposed and non exposed groups, relation of COHb concentration and passed time after the last smoking was expressed as exponential function, Y = 2.9182e-0.0083x and r-square of this function was 37.4%. Therefore it was more than 150 minutes that passed time after the last smoking was when COHb concentrations were measured as less than 1%. In conclusion, variable, that was statistically significant to COHb concentraion in the both CO exposed and non-exposed smokers, was a passed time after the last smoking. We suggest that you have to restrict the smoking of smokers at least 150 minutes in the exposed and non exposed group before COHb concentration measure in order to exclude smoking effects

Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

<P>Some patients with non-ST-elevation myocardial infarction (NSTEMI) have a total occlusive infarct-related artery. However, the long-term prognosis of these patients is uncertain, particularly for those who underwent an early invasive strategy. The aim of this study was to determine the clinical impact of total occlusion (TO) of an infarct-related artery (IRA) in these patients. A total of 2,094 patients with NSTEMI who underwent an early invasive strategy with percutaneous coronary intervention (PCI) in the Korea Acute MI Registry (KAMIR) were analyzed (TO group; 665 patients, and non-TO group; 1,429 patients).In-hospital and one-year clinical outcomes were compared between the two groups. The left circumflex (42.9%) and right coronary artery (31.9%) were the major IRA in the TO group, while the left anterior descending artery was more common as an IRA in the non-TO group (44.1%). In-hospital complications including death and cardiogenic shock occurred frequently in the TO group. Also, the rates of one-month and 12-month adverse cardiac outcomes were higher in the TO group. In the Cox-proportional hazard model, TO in IRA predicted 12-month all-cause death. In conclusion, NSTEMI patients with TO in IRA showed worse short- and long-term clinical outcomes compared with those of non-TO patients.</P>
