We reviewed 26 dapsone intoxication patients who had visited Severance Hospital Emergency Care Center from January 1991 to January 1995 : 13 of them ingested intentionally, but the other ingested accidentally. Among the admitted patients the highest and lowtheest initial value of methemoglobin level is 59.6% & 10.1%. The frequency of symptoms at presentation was following 16 patients complained cyanosis of lip area, 10 patients complained dyspnea, 4 patients complained mental change, 4 patients complained vomiting, 2 patients complained nausea. The inital level of methemoglobin was less than 50% except in one patient. In the view points of total doses of methylene blue used, less than 100mg was used in 9 patients(34.6%) but in one case, amount of 6400mg was loaded. There were 5 patients(19.2%) in September & 4 patients (15.4%) in January. In respect of result, there were 13 discharged cases (50%) for symptom improvement, and 5 mortality cases(19.2%). The transferred cases from Gangwondo account 19 patients(73.1%). All of them is not directly emergency care center visiting patients but transferred patients from remotely located hospitals. Dapsone intoxication results in severe tissue hypoxic symptoms from malfunction of normal hemoglobin thus only with appropriate available doses of methylene blue & activated charcoal, good outcomes will be expected. If aggressive therapy such as hemodialysis is introduced in treatment of severe dapsone intoxication, the outcomes may be slightly improved better than in other supportive care cases.

The increase of the spindle speed for high productivity in spinning process has been limited by the spinning tension and the friction between the traveller and ring. The rotating ring is one of the ways to be able to solve this problem. In this study, we studied the variation of spinning tension by traveller weight and speed variation of the fixed ring and the rotating ring. The result of this study, using a experimental model of rotating ring, revealed ; 1) traveller speed affects the spinning tension of fixed ring and rotating ring. 2) the traveller weight acts linearly on spinning tension. 3) the spinning tension of rotating ring is higher than that of fixed ring.

The present study was designed to analyse eariy-stage volley ball player's metacarpal bones aed phalanx histologically, pathologically by X-rays photographing. The main findings of the study were as follows; 1. Main attack plater among early-stage volley hall players, whose game carrier was longer than three years, was disposed to be shorter than assist attack player in epiphtseal line assimilation completion period. 2. Among ten early-stage volley ball player, J. H. Rho, J. J. Su & C. H. Kim almost completed epiphtseal line assimilation of metacarpal bones and phalanx. G. N. Kim & E. J. Kim wholly completed epiphtseal line assimilation with the acceleration phenomenon of metacarpal bones and phalanx resulting from the movement impulse by external power. M. H. O was completing epiphtseal line assimilation, G. H. Kang, W. H. Pack & M. S. Jung showed initial phenomenon. G. O. Wo made a complete failure in epiphtseal line assimilation of metacarpal bones and phalanx. 3. For all that the movement impulse by exteral power confimusously stimulated, early-stage volley ball player showed no pathological phenomenon. 4. Though the movement impulse through excessive training stimulated metacarpal bones and plalanx, early-stage volley ball player's bones and phalanx, carly-stage volley boll player's bones deformity and bones growth form was normal.

Air quality monitoring is a primary activity for industrial and social environment. The government identifies the pollutants that each industry must monitor. Especially, the VOCs(Volatile Organic Compounds), which are very harmful to human body and environment atmosphere, should be controlled under the government policy. However, the VOCs, which have not been confirmed in emission sources are very difficult to monitor. It is needed to develop the monitoring system that allow the continuous and in situ measurement of VOCs mixture in different environmental matrices. Gas chromatography and mass spectrometry are the most prevalent current techniques among those available for the analysis of VOCs. But, they need a large size analytical instrument, which costs a great deal for purchase and operation. In addition, it has some limitations for real time environmental monitoring such as location problems and slow processing time. Recently, several companies have commercialized a portable VOCs measurement systems, which cannot classify various kinds of VOCs but total quantities. We have developed a VOCs measurement system, which recognizes various kinds and quantities of VOCs, such as benzene, toluene, and xylene(BTX). Also, it can be used as a stand-alone type and/or fixed type in the vehicle with rack for real-time environmental monitoring.

폴리머 콘크리트를 이용하여 호안블럭을 디자인하고 제작하였다. 제품의 표준화를 위하여 '폴리머 복합체를 이용한 호안블럭 제조용 시방서'를 작성하였다. 폴리머 콘크리트의 우수한 물리적 성질을 이용하고 환경 친화적인 호안블럭을 제작하기 위하여 중앙에 원형 홀이 있는 I형, 원형, 반원형 호안블럭을 디자인하였다. 중앙의 홀은 바닥재로 채워질 수 있도록 했으며 인공적인 색상보다는 주위의 환경과 어울리도록 식물을 조경할 수 있도록 하였다. 또한, 시판중인 호안블럭과 호환이 되도록 크기를 결정하였으며 자외선 흡수제를 첨가하여 제작하였다. 시방서에서 제시하는 방법으로 휨강도 및 흡수율을 측정하였다. Polymer concrete was used to produce the stone block. In order to make the blocks standardize, 'Specifications for Producing Stone Block using Polymer Concrete' was suggested I-type, circular type and semi-circular type of stone blocks were designed and produced, in which a circular hole was made to utilize the excellent physical properties of the polymer concrete and to produce the eco-friendly stone block. Instead of using artificial color, the hole was designed to be filled with the ground soil and then grass can be planted to make the blocks harmonize with surroundings. The dimensions of blocks were determined to fit the cement concrete block on the market and the ultra violet absorber was added in producing the blocks. Flexural strengths and absorption of the polymer concrete blocks were measured by the method regulated in the specification.

송장호,구승우,백종화,정용보,이정순,최인철 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.5

Background: Intraoperative autotransfusion or residual blood in a cardiopulmonaty bypass (CPB) circuit has been used to reduce the need for an homologous blood transfutsion during cardiac surgery. However, it may contain some free hemoglobin released from damaged cells. The load of blood containing free hemoglobin may cause renal dysfunction. We measured the amount of free hemoglobin in backed blood, cell saver blood and CPB blood to evaluate what is the least hemolytic blood transfused in cardiac surgery. Methods: This study was performed in 20 patients undergoing cardiac surgery. In each patient, the banked blood, intraoperative salvaged blood with a cell saver and CPB residual blood were sampled at the end of the operation. The concentration of free hemoglobin, hemoglobin and platelet counts were measured in these blood samples and percent of hemolysis was calculated (%hemolysis = [free hemoglobin] / .free hemogloben + hemoglobin]) Results: In salvaged blood with a cell saver, CPB residual blood and banked blood, hemoglobin concentrations were 20.1 ± 2.7 g/dl, 8.0 ± 1.1 g/dl, and 22.2 ± 2.7 g/dl, respectively. Free hemoglobin concentrations were 336.6 ± 239.5 mg/dl, 49.2 ± 26.8 mg/dl, and 279.5 ± 167.5 mg/dl respectively. Platelet counts were 26.1 ± 22.2 × 10^3/mm^3, 116.8 ± 56.5 × 10^3/mm^3, and 94.9 ± 43.6 × 10^3/mm^3 respectively. % Hemolysis were 1.6 ± 1.1%, 0.6 ± 0.4%, and 1.2 ± 0.7% respectively. In the comparison between the salvaged blood with a cell saver and CPB residual blood, free hemoglobin concentration, % hemolysis, and platelet counts had positive correlations (r = 0.8, 0.7, and 0.6). Conclusions: In twenty cardiac surgeries, CPB residual blood had a lower free hemoglobin level than the other two blood groups. The platelet counts in CPB residual blood were higher than those in cell saver blood but did not differ from those in banked blood. Therefore, CPB residual blood was the least hemolytic blood among the three blood groups when a transfusion was performed in cardiac surgery. (Korean J Acesthesiol 2002; 43: 588~593)

Apoptosis의 유발을 억제하는 한약제를 파악하여 apoptosis와 관련된 정상적 또는 질병에 대한 연구에 자료를 제공하고자 방사선에 의해 유도된 apoptosis를 지표로 한의학적 처방에서 많이 사용되는 대표적 한약제(24종)의 효과를 검증하였다. 용안육, 산조인, 원지, 인삼, 복령, 목향, 천궁, 백작약, 승마, 시호 및 눈꽃동충하초 투여군에서 apoptosis는 감소되었으며, 이들 생약제는 apoptosis와 관련된 질병의 예방 및 치료에 적용할 수 있을 것이다. 추 후 이들 생약의 작용 기전에 대한 연구가 요구된다. This study was performed to determine the effect of several herbs on radiation-induced apoptosis in jejunal crypt cells. Longyanrou(Euphoris longana), Suanzaoren(Zizyphus vulgaris), Yuanzhi(Polygala tenuifolia), Rensan(Panax ginseng), Fuling(Poria cocos), Muxiang(Saussurea lappa), Chuanxiong(Cnidium officinale), Baishaoyao(Paeonia lactifolia), Shengma(Cimicifuga heracleifolia), Chaihu(Bupleurum falcatum) and Dongchongxiacao(Paecilomyces japonica) reduced the frequency of radiation-induced apoptosis(p<0.05). Although the mechanisms of this effect remain to be elucidated, these results indicated that Longyanrou, Suanzaoren, Yuanzhi, Rensan, Fuling, Muxiang, Chuanxiong, Baishaoyao, Shengma, Chaihu and Dongchongxiacao might be useful inhibitors of apoptosis, especially since these are relative nontoxic natural products.
