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.

<P><B>Abstract</B></P> <P>Colloids have been recognized to enhance the migration of strongly-sorbing contaminants. However, few field investigations have examined combined colloid transport via surface runoff and subsurface flows. In a headwater catchment of the upper Yangtze River, a 6m (L) by 4m (W) sloping (6°) farmland plot was built by cement walls to form no-flow side boundaries. The plot was monitored in the summer of 2014 for the release and transport of natural colloids via surface runoff and subsurface flows (i.e., the interflow from the soil-mudrock interface and fracture flow from the mudrock-sandstone interface) in response to rain events. The water sources of the subsurface flows were apportioned to individual rain events using a two end-member model (i.e., mobile pre-event soil water extracted by a suction-cup sampler <I>vs</I>. rainwater (event water)) based on <I>δ</I> <SUP>18</SUP>O measurements. For rain events with high preceding soil moisture, mobile pre-event soil water was the main contributor (generally >60%) to the fracture flow. The colloid concentration in the surface runoff was 1–2 orders of magnitude higher than that in the subsurface flows. The lowest colloid concentration was found in the subsurface interflow, which was probably the result of pore-scale colloid straining mechanisms. The rainfall intensity and its temporal variation govern the dynamics of the colloid concentrations in both surface runoff and subsurface flows. The duration of the antecedent dry period affected not only the relative contributions of the rainwater and the mobile pre-event soil water to the subsurface flows but also the peak colloid concentration, particularly in the fracture flow. The <10μm fine colloid size fraction accounted for more than 80% of the total suspended particles in the surface runoff, while the colloid size distributions of both the interflow and the fracture flow shifted towards larger diameters. These results highlight the need to avoid the application of strongly-sorbing agrochemicals (e.g., pesticides, phosphorus fertilizers) immediately before rainfall following a long no-rain period because their transport in association with colloids may occur rapidly over long distances via both surface runoff and subsurface flows with rainfall.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Subsurface flow was apportioned into rainwater and mobile pre-event soil water. </LI> <LI> The duration of no-rain period affects peak colloid concentration. </LI> <LI> Rainfall intensity and its temporal variation govern colloid discharge dynamics. </LI> </UL> </P>

목적 : 본 연구는 소음에 노출된 남자 근로자를 대상으로 장기간 소음 폭로가 혈청 마그네슘의 농도와 관련이 있는지를 검정하고 이러한 혈청 마그네슘의 농도가 또한 청력저하와 관련이 있는지를 파악하기 위하여 수행되었다. 방법 : 소음에 노출되는 178명의 연구대상자를 청력저하의 정도에 따라 세 그룹으로 분류하고, 구조화된 설문, 신체계측, 혈액검사 등으로 청력저하에 대한 감수성 요인과 혈청 마그네슘 등을 수집하고 측정하였으며, 대상자들의 청력 역치를 측정하기 위하여 청력검사를 실시하였다. 결과 : 본 연구의 결과를 요약하면 다음과 같다. 첫재, 청력저하에 관련된 개인의 감수성 인자라고 알려진 변수인 흡연유무, 나이, 혈압, 헤마토크리트, 콜레스테롤, 혈당 중에서 나이, 이완기 혈압이 단순분석에서 세 그룹간에 차이가 있었고(p〈0.05), 혈청 마그네슘의 농도 또한 세 그룹간에 통계적으로 유의한 차이가 있었으며(p〈0.05) 청력저하가 심할수록 혈청 마그네슘 농도는 낮아지는 경향을 보였다. 둘째, 그룹간의 소음 노출력은 차이가 있었지만 (p〈0.05) 청력보호구 착용상태에는 유의한 차이가 없었다. 셋째, 혈청 마그네슘 농도에 영향을 줄 수 있는 변수인 소음 노출 기간, 마그네슘 함량이 많은 음식의 섭취정도, 스트레스 수준 중에서 소음 노출기간이 혈청 마그네슘 농도와 유의한 상관관계를 보였고(p〈0.05) 노출기간이 길수록 마그네슘의 혈청농도는 낮아지는 경향을 나타내었다. 넷째, 주파수별로 청력저하와 관련된 감수성 요인들에 대한 다중회귀분석 결과 주파수 1,000 Hz에서는 연령이 좌,우측 귀 모두에서 유의한 변수로 채택되었으며 (p〈0.05), 연령이 증가할수록 청력저하가 심해지는 경향을 보였고, 주파수 4,000 Hz에서는 확장기 혈압, 소음 노출 기간, 혈청 마그네슘 등이 청력저하에 대한 감수성 요인으로 채택되었으며(p(0.05), 이완기 혈압이 높을수록, 소음노출 기간이 길수록, 혈청 마그네슘의 농도가 낮을수록 청력저하가 심해지는 것으로 나타났다. Objectivea : This study was conducted to investigate that the chronic noise exposure is associated with decreased serum magnesium concentrations and evaluate whether decreased serum magnesium is associated with noise induced hearing loss. Methods : One hundred seventy-eight male workers exposed to noise were selected and classified three groups by the degree of hearing loss. Hearing threshold levels were less than 30 dB at 1,000 Hz or less than 40 dB at 4,000 Hz In group I, more than 30 dB at 1,000 Hz or more than 40 dB at 4,000 Hz and 15 dB and less of pure tone average[PTA : (500 Hz+l,000 Hz+2,000 Hz)/3] in group II, more than 30 dB at 1,000 Hz or more than 40 dB at 4,000 Hz and over 15 dB of PTA in group III. Results : Serum magnesium concentrations were 2.42±0.26 mg/dl in group 1, 2.35±0.23 mg/dl in group n , 2.26±0.24 mg/dl in group II, respectively and significantly differ-ent between group I and group III (p〈0.01). It was negatively correlated with duration of the noise exposure as correlation coefficient (r) of -0.194 (p(0.05) . Analysis of the multipleregression on hearing threshold levels showed that serum magnesium, diastolic blood pres-sure, duration of the noise exposure were statistically significant at 4,000 Hz (p(0.05) . While only age was statistically significant at 7,000 Hz (p(0.05) . Conclusions : These results suggest that chronic noise exposure may induces decreasein serum magnesium concentrations and that its decreased concentration is related with noise induced hearing loss.

Neomorphogenesis of cartilage using chondrocyte-polymer constructs is a potential source for development of cartilage reconstruction. Current tissue engineering techniques of neocartilage rely on in vivo implantation of polymer-chondrocyte constructs. The purpose of this study was to find a way to bioengineer cartilage in vitro by entrapping chondrocytes in a molded autologous fibrin glue. Chondrocytes isolated from the cartilage of rabbit joints were combined with fibrinogen extracted by a single cryoprecipitation of autologous plasma, and they were then polymerized with thrombin to create a fibrin glue with a final cell density of 2.5x10?? cells/ml. The collagen for a control study was used as a polymer. The polymer-chondrocyte constructs were cultured for 4 weeks and the fibrin-chondrocyte constructs molded in the shape of a human ear were cultured for 6 weeks in vitro. Morphometric, histochemical, and histomorphometric analysis including glycosaminoglycan quantitation confirmed the following results: 1) Highly-concentrated autologous fibrinogen was easily extracted by a single cryoprecipition of autologous olasma. 2) The fibrin-chondrocyte constructs demonstrated the presence of actively proliferating chondrocytes with the production of cartilaginous matrix(collagen and glycosaminoglycan) at 1 week after culture, as well as gross and histologic evidence similar to those of normal cartilage at 3∼4 weeks after culture. 3) The collagen-chondrocyte constructs demonstrated lower degrees of hardness and transparency, as well as a lower density of cells and glycosaminoglycan during the culture period. 4) Neocartilage generated from fibrin-chondrocyte constructs in the shape of a human ear nearly retained their original configuration and size without degeneration for 6 weeks of culture in vitro. This study demonstrated a novel method for bioengineering the molded cartilage in vitro using autologous fibrin glue as a matrix scaffold. The generated cartilage showed gross and histologic evidence similar to those of normal cartilage, retaining the original gross dimension. With further refinement, this may be a new application of tissue engineering for the reconstruction of cartilage.

Struma ovarii is a mature cystic teratoma of the ovary. It is an uncommon tumor accounting for 2.7% of all ovarian teratomas and composed totally or in overwhelming proportion of thyroid tissues. When thyroid tissue constitutes more than 50% of the tumor, it is usually called a struma ovarii. Grossly, they are encapsulated, several centimeters in diameter and have a red, shiny, and meaty surface. Microscopically, the tumor is composed of mature thyroid tissue consisting of various sizes, lined by a single layer of columnar or flattened epithelium. The clinical behavior is benign and simple excision is adequate treatment. We have experienced a case of struma ovarii arising from the left ovary. So, we report this case with review of literatures.
