저자들은 간이식을 받은 환자에서 조직 배양 검사를 통하여 진단된 A. fumigatus에 의한 화농성 고관절염을 경험하였기에, 문헌 고찰과 함께 보고하는 바이다. Septic arthritis is an uncommon finding of invasive Aspergillosis. It can be caused by direct inoculation, Post-surgical infection, and hematogenous spread. Articular aspergillosis often involves the knee. A 49-year-o1d man who received a liver transplant in China on two months ago, due to liver cirrhosis caused by hepatitis B virus was admitted because of left side hip pain. Hip MRI showed joint effusion and bony destruction of the left hip and acetabulum. Incision and drainage was done and Aspergillus fumigatus was isolated from the resected tissue. After eight weeks of amphotericin B therapy, total hip replacement arthroplasty was done. Oral itraconazole 400mg/day was prescribed for six months after operation. The patient is now doing well without physical restriction.

김승환,양영모,하영록,정성필,유인술,김인병 대한응급의학회 2001 대한응급의학회지 Vol.12 No.3

Background: The ischemia responsive protein 94 kDa(irp94) gene belongs to the heat shock protein 110 family and was isolated in 1999 from rat brain by transiently induced forebrain ischemia. The PC12 cell is the pheochromocytoma cell line of rat, which is differentiated to a sympathetic neuron-like cell by the stimulation of a nerve growth factor. This study is to determine whether irp94 is expressed when an ischemia-like condition is induced by ATP depletion in cultured PC12 cells in vitro. Methods: PC12 cells were maintained as monolayer cultures in RPMI-1640 medium(Sigma) supplemented with 10% horse serum, 5% fetal bovine serum, 5 mg/ml transferrin, and 1 mg/ml insulin in a humidified 5% CO2 incubator at 37℃. The ATP depleting agent antimycin A was added at concentrations of 1, 2.5, and 5 μM to simulate ischemia, and 10 μg/ml of tunicamycin, which is expected to express heat shock protein maximally, was used as a positive control. The cells were harvested after a 60-minute incubation, and the total RNA was extracted. The reverse transcription polymerase chain reaction(RT-PCR) was performed to use 501 bp irp94 cDNA as a molecular probe, and the expression of irp94 mRNA was analyzed by northern blotting. Results: The irp94 mRNA expression was enhanced, compared to the negative control group, as the concentration of antimycin A was increased. Conclusion: This study suggests that irp94 mRNA expression is enhanced as the severity of ischemia is increased. Thus, it is possible to investigate the mechanism of ischemic neuronal injury indirectly by using this in-vitro model of neuronal ischemia.

Objectives : The increased prevalence of asthma over the last 30 years has been reported from many different countries, including Korea. The increased prevalence may be due to increased exposure to indoor air pollutants. Methods : In this study, the relationship between residential environments and airway hyper-responsiveness has been examined among 280 family members. The bronchial hyper-responsiveness was expressed as the log-transformed slope of FEV1 decrease over the log-transformed dose of methacholine concentration (BRindex). Simple regression analysis was done for the effect of sex, age, atopic status, and residential environments including active and passive smoking exposures on airway responsiveness. Based on simple regression results, multiple rwegression analysis was performed for total group and also according to sex. Results : The mean of BRindex of residents living in gas boiler heating houses was higher than that of central heating system (p=0.014). Smoking status was a significant determinant of bronchial hyper-responsiveness in both genders, male (p=0.017), female (p=0.022). In the male group the mean of BRindex of current smokers was significantly higher than those of ex-smokers and non-smokers, and the mean of BRindex of passive smokers was higher than that of non-smokers, but statistical significance was border-line(p=0.069). In female group, the mean of BRindex of kerosene stove users was higher than that of non-users (p=0.057). Conclusions : This study suggests that indoor air pollutants including type of heating, passive smoking and kerosene stove use can contribute to the increase in asthma prevalence in Korea.

This paper deals with an optimal process control problem in production of hull structural steel plate with high defective rate. The main quality characteristic(dependent variable) is the internal quality(defect) of plates and is dependent on process parameters(independent variables). The dependent variable(quality characteristics) has three categorical ordinal data and there are 35 independent variables(29 continuous variables and 6 categorical variables). In this paper, we determine the main factors and to develop the mathematical model between internal quality predicted probabilities and the main factors. Secondly, we find out the optimal process condition of main factors through analysis of variance(ANOVA) using simulation. We consider three models to obtain the main factors and the optimal process condition: linear, quadratic, error models.

Purpose: The gastrointestinal (GI) tract is the most common site of extranodal non-Hodgkin's lymphoma (NHL), which is increasing in incidence, but there is no established optimal treatment modality. Thus, this study was investigated the clinicohistologic feature, the therapeutic modalities, and the prognosis for GI-NHL, as well as the factors affecting it. Methods: We retrospectively analyzed 45 patients who had been diagnosed as having GI-NHL and had been followed up from July 1994 to February 2005 at Soonchunhyang University Hospital. The patients were divided into groups according to the site of origin and to various other features, and the survivals of the various groups were compared. The modified Ann Arbor system and WHO classification were adopted for staging and histopathologic classification, respectively. Results: GI-NHL of the stomach, small bowel, ileocecal region, and colon occurred in 28 patients (62.2%), 5 patients (11.1%), 3 patients (6.7%), and 8 patients (17.8%), respectively, In one patient, the entire gastrointestinal tract was diffusely involved. The median age of patients was b5 years (25~78 years), and male-to-female ratio was 1:1.1. Fourteen patients were in stage Ⅰ, 24 in stage Ⅱ, 4 in stage Ⅲ, and 3 in stage Ⅳ. Surgical resection was performed in 19 patients, and combination chemotherapy was performed in 43 patients. Surgical resection only was performed in 4 patients, Chemotherapy only was performed in 26 patients. The expected overall 5 year survival of 45 patients was 39.6%, and there was a significant survival difference between the stages, but between sites of origin (p=0.842). The most important factors influencing the survival was the stage and other factors were not significant. Conclusion: The stomach was the most common site of GI-NHL. Most GI-NHL were localized Stage was the most important prognostic factor. However, Prospective randomized studies are needed to approve the therapeutic modality.

Background: From many previous studies, Pulmonary hypertension is the known independent predictive factor of the mortality in COPD. Also pulmonary hypertension is the major cardiovascular complication of COPD and is associated with the progression to cor pulmonale and poor prognosis. Author want to analyze the correlation between pulmonary hypertension and the severity of COPD which are classified by forced expiratory volume in one second, and the extent of progression to corpulmonale. Methods: Retrospectively we investigated the medical records of 118 patients with COPD who had pulmonary function test and echocardiogaphy more than one times during one-year follow-up (from June, 2005 to May, 2006) at respiratory division in chosun university hospital, and then 50 patients were enrolled in this study. We classified the severity from FEVl in pulmonary function test based on the GOLD guideline, also this was comparably analyzed with RVSP, RVIDd, Visual Grading from echocardiography. Results: 16 patients out of 50 were classified as moderate severity, 25 patients were severe, and 9 patients were very severe group. RVSP was higher in more severe groups than less severe groups but when it comes to pulmonary hypertension that RVSP is over 35 mmHg, there was no valid difference lies in those groups. As FEVl decreases RVSP and RVIDd increases, and observed relationship between RVSP which was classified as below 35 mm and above 35 mm groups and visual grading which was classified as normal and dilatated groups revealed valid correlation, Conclusion: As pulmonary function decreases, progression to pulmonary hypertension and cor pulmonale increases but there was no remarkable difference of prevalence in above moderate severity groups. 연구배경 폐고혈압은 이전의 많은 연구에서 만성폐쇄성폐질환에서 독립적인 사망의 예측인자로 알려져 있다. 또한 폐고혈압은 만성폐쇄성폐질환의 주요한 심혈관계 합병증이며, 폐성심으로의 진행 및 불량한 예후와도 관련되어 있다. 이에 저자는 폐고혈압과 1초간 노력성호기량으로 분류되는 만성폐쇄성폐질환의 중증도 및 폐성심으로의 진행 정도를 비교 분석하여 이들의 상관관계를 밝혀보고자 한다. 방법 2005년 6월부터 2006년 5월까지 1년 동안 본 병원 호흡기 내과에서 폐기능검사와 심장초음파 검사를 각각 1회 이상 시행한 적이 있는 118명에 한하여 의무기록을 후향적으로 조사하여 이 중에서 50명을 대상으로 하였다. 폐기능검사 시행 결과 얻은 1초간 노력성호기량을 바탕으로 GOLD guideline에 따라 중증도를 분류하였으며 이를 심초음파 시행 결과 얻은 우심실수축기압, 확장기말 우심실내부간격, 시각등급과 비교분석하였다. 결과 대상 환자 50명중 16명은 중등증, 25명은 중증, 9명은 최고중증 그룹으로 분류되었다. 우심실수축기압은 중증도가 높은 그룹에서 낮은 그룹에 비해 더 높게 나타났으나 폐고혈압에 해당하는 우심실수축기압이 35 mmHg이상인 환자에 있어사는 각 그룹간에 유의한 차이를 보이지 않았으며, 확장기말 우심실내부간격, 시각등급 또한 중증도와 유의한 차이를 보이지 안항ㅆ다. 1초간 노력성호기량이 감소함에 따라서는 우심실수축기압, 시각등급은 증가하였으며 우심실수축기압을 35mmHg 미만과 이상인 그룹으로, 시각등급을 정상과 확장이 있는 그룹으로 분류하여 비교한 결과에서는 유의한 상관관계를 나타냈다. 결론 폐기능이 감소할수록 페고혈압 및 폐성심으로의 진행이 증가하였으나 폐기능검사에서 중등도 이상의 그룹에서 유병률의 차이는 크지 않았다.

The caudal subnucleus of the spinal trigeminal nucleus (medullary dorsal horn; MDH) is implicated in the processing of nociceptive information in the orofacial region. In the present study, whole cell patch clamp recordings were carried out on MDH neurons in brainstem slice of neonatal rats to investigate the characteristics of spontaneous excitatory postsynaptic currents (sEPSCs) and the roles of nociceptin/orphanin FQ on excitatory synaptic transmission. In the presence of strychnine (1 μM) and bicuculline (20 μM), spontaneous inward currents at -70 mV were observed. The baseline frequency, amplitude and decay time constant of sEPSCs were 2.0 ± 0.5 Hz, 23.0 ± 1.8 pA, 3.8 ± 0.2 ms, respectively. sEPSCs were mediated by non-NMDA and NMDA receptors. The specific AMPA receptor antagonist GYKI-52466 (50 μM) completely blocked the non- NMDA mediated sEPSCs, indicating that they are mediated by an AMPA-preferring receptor. Perfusion of the opioid orphan receptor (ORL_1) adonist nociceptin (3 μM) reduced the frequency of sEPSCs and miniature EPSCs (mEPSCs). The effects of nociceptin were blocked by the selective ORL_1 receptor antagonist [Nphe'] nociceptin(1-13)NH_2 (3 μM) and were not affected by the non-specific opioid receptor antagonist naloxone (10 μM). To investigate the specificity of this synaptic inhibition, we selectively activated the nociceptive C fibers with capsaicin, which induced a strong increase in the frequency of sEPSCs. In the presence of nociceptin, the response to capsaicin was diminished. In conclusion, these results suggest that nociceptin inhibits excitatory synaptic transmission in the MDH by acting on presynaptic ORL_1 receptors.

Objectives: Since 1994, the number of North Korean defectors, escaping North Korea and entering South Korea, has in creased rapidly.The Government has provided most of te support for the defectors' adaptation to their new society.But as the number of defectors has increased, and the support needs have become more various, the support of volunteers from non-governmental organization(NGO) has become very important.To raise the level of the success and effectiveness of the support from the volunteers, their experiences were surveyed and analyzed. Methods: This study surveyed 83 volunteers of 7 NGOs involved in helping North Korean defectors' adaptation to South Korean society-48 men and 34 women. Results: In their relationships with defectors, women volunteers have more difficulties in their first 3 months.However volunteers in their 50s and 60s tend to have more stable and better relationships with defectors than younger volunteers.Many volunteers statedexperiences of human difficulties with defectors, for example, mistrust and anxiety in human relationship (n=34, 41.0%), psychological maladjustment(n=19, 22.9%), different ways of thinking and culture(n=17, 20.5%), economic difficulties(n=10, 12.0%), and lack of independence spirit(n=6, 7.2%).The volunteers said they have feelings of goddwill toward defectors when defectors showed warm heart(n=30, 36.1%), politeness(n=30, 36.1%), positive and active character (n=24, 28.9%), strong will(n=17, 20.5%), and plainness (n=14, 16.0%).The volunteers stated an absence of goodwill feelings to defectors when defectors showed uncompromising and aggressive attitudes (n=29, 34.9%), lack of independent will (n=28, 33.7%), selfishness (n=18, 21.7%), and avoidance of making human relationship (n=16, 19.3%).as for adequate training before commencing activity, 5 volunteers(6.0%) said they had received enough education before their activity, 31(37.3%) relatively enough, 38 (45.8%) relatively not enough, and 9 (10.8%) absolutely not enough education.If they were the owners of al company, 27 volunteers (51.9%) sanid they would want to thire defectors even if the defectors did not have the required ability. Conclusion: These results showed that NGO's volunteers have a friendlier attitude to defectors than policemen n charge and public officials, which is their strong point.Women volunteers experience more difficulties in their early relationships with defectors, suggesting the need for a specific pre-education program for women volunteers.Furthermore, NGOs would benefit from an increase in the number of volunteers in their 50's and 60's.Both volunteers and defectors need to understand each othe to a deeprer extent and the characteristics to which South Korean volunteers feel goodwill need to be used n their education.
