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 aim of this study was to develop a transgenic petunia with enhanced resistance to sulfur dioxide (SO₂) gas by stacking two genes, SOD2 and NDPK2, which are both known to confer resistance to abiotic stresses. The first-generation hybrids (TF1) were obtained through reciprocal crosses between an SOD2-transgenic line SOD2-2-1-1-35(T₄)[S(T₄)] and an NDPK2- transgenic line NDPK2-7-1(T₂)[N7-1(T₂)]. Approximately 32.1-73.0% of the first-generation hybrids (TF₁) carried both SOD2 and NDPK2 genes. These hybrids showed 2.6 and 5.1 times less damage than hybrids carrying only SOD2 or NDPK2 genes, respectively, when they were treated with SO₂ gas at 30 ppm. This confirmed that the heterozygous hybrids were more resistant to SO₂ than the hybrids carrying either one of the resistance genes. Second-generation hybrids (TF₂) were obtained by selfing the TF₁ individuals. We confirmed the expression of the stacked genes in the TF₂ hybrids by phenotypic observation of their response to SO₂ gas at 30 ppm as well as using RT-qPCR and photosynthetic efficiency.

Objectives: To investigate the rate of first-line eradication and the rate of second-line eradication of Helicobacter pylori (H. pylori) from 2001 to 2010 in a single institute in Seoul. Methods: Among the 2,717 patients who received H. pylori eradication treatment from 2001 to 2010 at Ewha Womans University Mokdong Hospital, the medical records of 1,466 patients who satisfied the condition of execution of upper gastrointestinal endoscopy, positive H. pylori eradication results at 6~8 weeks after eradication therapy were reviewed retrospectively. Then the first-line and second-line eradication rates and the eradication rates according to endoscopy findings were also compared. Results: The first-line eradication rate was 77% H. pylori eradication rate for the last 5 years was continuously increasing and no sign of decline was observed even for the whole 10 years. The rates of eradication related to endoscopic findings showed statistical significance (P<0.001) of 79.8% and 70.1% each for peptic ulcer and non-ulcerative gastric diseases, respectively. Conclusion: In this study, no decrease in tendency of first-line eradication rate could be found. In addition, the patients with the non-ulcerative gastric disease seemed to show significantly lower eradication rate. This finding suggests eradication treatment may be affected by the category of gastric diseases, and careful considerations should be taken assessing the effects and needs for the H. pylori eradication treatment.

김소연,박정길,허복,김현철 大韓齒科保存學會 2005 Restorative Dentistry & Endodontics Vol.30 No.1

이 연구의 목적은 만곡이 삼한 근관에서 ProTaper(R)를 수동으로 사용하는 방법, 엔진 구동으로 사용하는 방법, 그리고, 치관부는 엔진 구동으로 치근단부는 수동으로 사용하는 세 가지 방법의 근관 성형 능력을 비교하기 위한 것이다. 근관 길이가 170mm이고 근관 입구에서 10mm 떨어진 부위에서 만곡이 시작되며 평균 40도의 단일 만곡을 가지는 투명한 레진 블락 30개를 사용하였다. 각 군당 10개의 레진 블락을 사용하였으며, 수동형 ProTaper(R)로 전체근관을 성형한 군형 M군, 엔진 구동형 ProTaper(R)로 전체근관을 성형한 군을 R군, 근단부는 수동형 ProTaper(R)를, 치관부는 엔진 구동형 ProTaper(R)를 사용하여 성형한 군을 H군으로 하였다. 각각의 블락을 성형하고 각 군별 근관 성형시간을 기록하였다. 근관 성형전과 후의 이미지를 중첩하여 근단공으로부터의 수직 이동 거리 1, 2, 3, 4, 5 그리고 6 mm 위치에서 수평선을 긋고 총 근관폭경, 근관 만곡 내외측 삭제량, 근관의 변위, 중심 이동률을 평가하여 다음과 같은 결론을 얻었다. 1. 근관 성형시간은 R군, H군, M군 순으로 짧았고, 세 군 사이에는 유의한 차이가 있었다(p < 0.05). 2. R군이 전체적으로 삭제량이 많은 경향을 보였으나, 1, 3 mm를 제외하고는 차이가 없었다(p > 0.05). 3. 만곡내측 삭제량에 있어서는 1 mm 지점에서는 R군이, 6 mm 지점에서는 H군이 컸지만 (p < 0.05), 나머지 지점에서는 차이가 없었다. 만곡외측 삭제량은 1 mm 지점에서만 R군이 컸다 (p > 0.05). 4. H군, R군은 1, 2, 3 mm 지점, M군은 1, 2 mm 지점에서 만곡외측으로의 변위를 보였고, 그 외의 지점에서는 내측변위를 보였다. 각 군 간의 변위차이는 6 mm 지점에서 H군이 컸다(p < 0.05). 5. 근관의 중심 이동률은 6 mm 지점에서 H군이 R군에 비해 유의하게 컸지만 다른 모든 위치에서는 차이가 없었다(p < 0.05). 본 실험결과를 토대로 할 때, 각 평가 항목에서 측정 위치에 따라 약간씩 차이가 있었으나, 중심 이동률은 대부분의 위치에서 유의한 차이가 없었다. 따라서 만곡 근관을 성형시에는 세 가지 방법 중 어느 것이 더 유용하다고 보기 어렵다고 판단된다. The purpose of this study was to compare the shaping ability of the three ProTaper instrumentation techniques in simulated canals. Thirty resin blocks were divided into 3 groups with 10 canals each. Each group was instrumented with manual ProTaper (Group M), rotary ProTaper (Group R), and hybrid technique (Group H). Canal preparation time was recorded. The images of pre- and post-instrumented root canals were scanned and superimposed. The amounts of canal deviation, total canal width, inner canal width, outer canal width and centering ratio were measured at apical 1, 2, 3, 4, 5 and 6 mm levels. 1. Canal preparation time was the shortest in R group (p <0.05). 2. The amounts of total canal width in R group was generally larger than the other groups, but no significant differences were observed except at the 1, 3 mm levels (p ) 0.05). 3. The amounts of inner canal width in R group was larger than M group at the 1 mm level and H group was larger than R group at the 6 mm level (p < 0.05). The amounts of outer canal width in R group was larger than H group only at the 1 mm level (p <0.05). 4. The direction of canal deviation in H, R group at the 1, 2, 3 mm levels was outward and that in M group at the I, 2 mm levels was inward. The amounts of canal deviation in H group was larger than R group at the 6 mm level (p <0.05). 5. The amounts of centering ratio in H group was larger than R group at the 6 mm level (p <0.05).

Benzethonium chloride-containing egg phosphatidylcholine-based liposomes (BC/EPC-LIPOs) were developed for lung-targeted drug delivery. BC/EPC-LIPOs were fabricated via thin-film hydration method with various BC-to-EPC molar ratios of 1:4 (F1), 1:1 (F2), and 4:1 (F3). Cyanine5.5 (Cy5.5) was loaded as a fluorescent probe for the biodistribution study during the film-forming step. BC/EPC-LIPOs were evaluated by using dynamic light scattering analysis, where the mean diameter and zeta-potential values of F1, F2, and F3 were observed to be 69.5 ± 3.1 nm and 50.06 ± 1.00 mV, 59.0 ± 2.3 nm and 51.30 ± 2.98 mV, and 694.2 ± 243.3 nm and 55.01 ± 3.16 mV, respectively. To evaluate the lung distribution efficiency of the developed liposomes, F1 and F2, which possess suitable particle sizes for the intravenous administration, were injected into the tail vein of ICR mice. At 6 h post-injection, the lung, liver, kidney, heart, spleen, and brain were dissected, and the radiant efficiency (RE) values of the or- gans were measured using the near-infrared fluorescence imaging method. The lung RE value of F2 was 1.69-fold higher than that of F1, indicating a more efficient lung targetability of F2. This phenomenon can be attributed to the higher content of BC in F2 than F1. Considering the lung-targetability, as well as the biocompatible natures of BC and EPC, the developed BC/EPC-LIPOs can be used as an efficient lung-targeted drug delivery system.

술은 식품, 약품 또는 중독성 물질로 분류되며 기분 전환제 또는 정신자극 약품으로 작용한다. 술은 국민의 신체적 정신적 건강을 해치는 물질로 계속적으로 주목을 받고 있으며 이를 상습 하는 사람의 경우 영양장애뿐 아니라 간, 췌장, 소화기관, 뇌, 심장, 근육과 생식기관등 신체의 모든 기관에 손상을 입힌다고 한다. 술의 남용은 결핵(tuberculosis), 기회감염(oppotunistic infections), 뇌와 목의 종양, 자가면역질환(autoimmune disease)의 발생 정도가 높으며, 면역체계와의 관련성 역시 제기되고 있다. 알코올에 의한 면역부진은 세포 매개성 면역(cell-mediated immminity)에서 가장 두드러지며, 이로 인해 결핵의 이환이나 간염과 인체면역결핍바이러스(HIV infection)과 같은 비루스에 의한 감염이 쉽게 일어날 수 있다. 알코올에 의해 T cell의 기능은 손상되거나 분비 이상이 초래될 수 있으며, Natural killer cell의 활성이 감소되는 등의 면역 기능의 손상을 가져올 수 있다. 이러한 면역기능의 손상은 간질환, 암, 기타 감염에 쉽게 노출될 수 있는 환경을 제공하게 된다. 결국 알코올 섭취와 관련된 특정질환에서 알코올은 immnomodulator로서 작용하여 여러 질환의 원인 물질로 작용될 수 있다.

秦始皇陵 출토 병용의 服飾 硏究 : 胡服과의 관련성을 중심으로

김소현,조규화 한국의류학회 1993 한국의류학회지 Vol.17 No.1

This study intends to find out the correspondence of the costumes of the terracotta warriors at the tomb of Qin Shi Huang to the dress of nomadic people. The Chinese took the dress of nomadic people into their costumes so that they might practise shooting arrows from horse back in the Age Of Wars. The terracotta warriors at the tomb of Qin Sin Huang provide us with substantial evidence that Qin Dynasty inherited the system of wearing the dress of nomadic people from Zhao. Figures of calvarys wear the jackets of nomadic people, but figures of other warriors wear Han jackets. This means that the aim of taking the dress of nomadic people is to be convenient in practising shooting arrows from horse back. Nomadic people adjusted their jackets to left, because they road on a horse from left for being the tunga only on the left. But calvarys adjusted their jackets to right. In those days, China didn't have a tunga. So there was no necessity for riding from left. And Chinese were accustomed to adjusted their jackets to right. This is the reason why calvarys adjusted their jackets to right, though they wear the dress of nomadic people. Soldiers wear trousers. Some have puttee, some have their leg bounds. All the soldiers tightened their coats or jackets with belts which were inhereted from nomadic people. They wear either shoes or short boots. The figures are classified according to rank, espicially in their hats and armours. General wears a cap adorned with pheasant' feathers, officer wears an unadorned cap, and men are hatless or in turbans. Calvary's headgear looks like a p'ing-chin-tse which was correspondence to the headgear of nomadic people. Soldiers wear armours according to duty, and armours are differentiated by rank. From the state of terracotta warriors, I think that the warriors were made from BC 246 to BC 210 which is equal to the date of making the tomb of Qin Shi Huang. Then the date of making the terracotta warriors was between 60 and 100 years since the king Wu Ling of the state of Zhao took the dress of nomadic people.

홍소현,김도연,김태오,배지윤,이신아 이화여자대학교 의과학연구소 2014 EMJ (Ewha medical journal) Vol.37 No.S

자발성 신파열은 외상 혹은 수술 등의 병력 없이 신장 피막 혹은 신장 주위 혈종이 자발적으로 발생하는 드문 질환으로, 원인으로는 요로 결석[1], 결핵, 신우신염, 신농양 같은 감염성 질환이나[2] 신장의 종양 및 신장 이식 수술 후[3], 후천성 낭성 신환[4] 등이 관련이 있다. 그 중 복막 투석 환자에서 낭성 신질환에 의한 자발성 신파열은 국내 보고가 있었으나 요로감염에 의한 자발성 피막하 혈종을 동반한 신파열은 문헌 보고가 없었다. 저자들은 요로감염으로 진단된 환자에서 피막하 혈종을 동반한 신파열 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

胡服硏究 : 王國維의 胡服考를 중심으로 With the "Ho Bok Ko(The Study on the Foreign Costume)" Written by Wang Kuk Yu

金素賢 배화여자대학 1993 培花論叢 Vol.11-12 No.-

I have focused my study on the transition of mode in costume shown by the Chinese with the "Ho Bok Ko" written by Wang Kuk Yu. The traditional dress style of Chinese is the one piece style, but the Chinese took the "Ho Bok" (the dress of nomadic people) into their costumes so that they might practise shootjng arrows from horse back in the Age of Wars. The "Ho Bok", that is "Ko Sup" worn since the `Decree of Ho Bok' by the King Wu-Ling of the state of Zhao, and the "Ban Lyung" which is the costume of Xianbei, "Bok Doo" since Southern-Northern Dynasties was worn without the concept of "Ho Bok". From the late Han Dynasty, Chinese actively interchanged with the countries to the west of China, and largely introduced the garment of the Tarim Basin called Suyeuk (west border). Originally, the Tarim Basin was Iranian place of residence. However, its costume had been Turkinized, because it had been under the power of Turk before the T'ang Dynasty. The "Ho Bok" of the T'ang Dynasty introduced from this place, therefore, was influenced by Persia, but in its style of costume, there was a great influence of Turk. As known to all, in music, dance, fine art, and craft along with costume, the foreign customs (exoticism) was remarkable. However the exoticism in costume has a characteristic which was for more greatly influenced by Turk than Persia. The new style of costume in the T'ang Dynasty was to wear "Bun Lyung" on tight trousers, and to hang down "Chup Sup Chil Sa" onto belt. "Bun Lyung" which had been recognized vaguely as being derived from Persia was not a Persian Style, But Turks style. The Persian costume was tunic, not caftan, while the "Bun Lyung" was a Turks style similar to today's lapel of men's suit. Thanks to the open-door foreign policy of the T'ang Dynasty, the various foreign elements in costume were introduced, but most of them were a merely temporary vogue of a time. But wearing the two piece style with jacket and trousers was in general use, and "Ban Lyung" performed its role of breaking from the "Jick Lyung", and these were the most innovative change through the history of the Chinese costome.

This study was performed to evaluate the effect of persimmon vinegar on serum lipid components in the hypercholesterolemic Sprague-Dawley male rats. Forty rats were divided into four groups and fed diets containing 1% cholesterol for 4 weeks. Experimental diets added to distilled water, 1.5%, 3%, and 7% persimmon vinegar(PV) as drinking water. Concentration of total cholesterol, LDL and HDL cholesterol, triglyceride in serum and activity of AST, ALT in serum were assayed. Average food intake, weight gain and FER of experimental rats were not significantly different by contents of persimmon vinegar. Concentration of total cholesterol and LDL cholesterol in serum were lowest in 7% persimmon vinegar group. However concentration of HDL cholesterol in serum was highest in 3% persimmon vinegar group. Concentration of triglyceride in serum was significantly lower in persimmon vinegar group than control group. Activities of AST and ALT in serum were lowest in 7% persimmon vinegar group. The results in this study suggest that persimmon vinegar is effective in lowering serum triglyceride level.
