시간적-공간적으로 가대리 화강암과 관련되어 형성된 월성 다이아튜림은 천수에서 유래된 용액에 의해 광화되어 있다. 이 광상에서 광석광물은 황철석, 유비철석, 섬아연석이 대부분이고 극소량의 자철석, 자류철석, 황동석, 석석과 Pb-Sb-Bi-Ag 계의 광문이 있다. 유체포유물, 유비철석에서의 비소함량과 섬아연석의 철 함량에 의해 계산된 비소-아연 광화 온도는 약 $350^{\circ}C$에 이르며, 염농도는 0.8에서 4.1 equ. wt % NaCl이다. 공생을 이루는 황철석-자류철석-유비철석은 $H_2S$ 주요 환원황으로 작용했으며, $300^{\circ}C$에서 산출한 광황용액은 $10^{34.5}$ < ${alpha}_{O_2}$ < $10^{-3}$, $10^{-11}$ < $f_{S_2}$ < $10^{-8}$, $10^{-2.4}$ < ${alpha}_{H_2S}$ < $10^{-1.6}$이고 pH는 견운모 안정범위인 5.2이하이다. 유화광물의 유황동위 원소비는 1.8에서 5.5%로서 유황은 마그마에서 기원되었다. 광화대에서의 탄산염 광물의 탄소 동위 원소비는 -7.8에서 -11.6%이고 산소 동위원소 값은 천수의 유입이 있었음을 의미한다. 지화학적 자료로 보아 광화용액은 마그마에 천수가 유입되어 마그마 열원의 영향하에 지하 심부 순환관정을 거쳐 형성된 것으로 해석된다. The Weolseong diatreme was temporally and spatially related to the intrusion of the Gadaeri granite, and was -mineralized by meteoric aqueous fluids. In the Nokdong As-Zn deposit, pyrite, aresenopyrite and sphalerite are the most abundant sulfide minerals. They are associated with minor amount of magnetite, pyrrhotite, chalcopyrite and cassiterite, and trace amounts of Pb-Sb-Bi-Ag sulphosalts. The AsZn ore probably occurred at about $350^{\circ}C$ according to fluid inclusion and compositional data estimated from the arsenic content of arsenopyrite and iron content of sphalerite intergrown with pyrrhotite + chalcopyrite + cubanite. Heating studies of fluid inclusions in quartz indicate a temperature range between 180 and $360^{\circ}C$, and freezing data indicate a salinity range from 0.8 to 4.1 eq.wt % NaCl. The coexisting assemblage pyrite + pyrrhotite + arsenopyrite suggests that $H_2S$ was the dominate reduced sulfur species, and defines fluid parameter thus: $10^{-34.5}$ < ${\alpha}_{S_2}$ < $10^{-33}$, $10^{-11}$ < $f_{S_2}$ < $10^{-8}$, -2.4 < ${\alpha}_{S_2}$ < -1.6 atm and pH= 5.2 (sericte stable) at $300^{\circ}C$. The sulfur isotope values ranged from 1.8 to 5.5% and indicate that the sulfur in the sulfides is of magmatic in origin. The carbon isotope values range from -7.8 to -11.6%, and the oxygen isotope values from the carbonates in mineralized wall rock range from 2 to 11.4%. The oxygen isotope compositions of water coexisting with calcite require an input of meteoric water. The geochemical data indicate that the ore-forming fluid probably was generated by a variety of mechanisms, including deep circulation of meteoric water driven by magmatic heat, with possible input of magniatic water and ore component.

N/A To investigate the usefulness of serum lipids and apolipoproteins as indices of risk factors for coronary artery disease (CAD) and to know the effects of regular exercise on the serum lipids and apolipoproteins, we measured the serum lipids and apolipoproteins in the patients with coronary artery disease, athletes and normal control persons. The study subjects included 67 patients with CAD (57. 8±11.2yr), 22 athletes (21.5±2.1yr) and 62 normal control persons (34.3±11.4yr). 1) In the patients with CAD the serum total cholesterol (TC) was 177. 2±38.5 mg/dl and the HDL-cholesterol (HDL-C) was 39.0±11.2mg/dl. In the normal control persons TC was 162.5±33.5 mg/dl and HDL-C was 42.4±12.6mg/dl, which were not significantly different from the values of CAD patients. 2) The serum apolipopratein A (Apo-A) was significantly lower (201.9±39.6mg/dl, p<0.05), and the apolipoprotein B (Apo-B) was significantly higher (132.3±29.7 mg/dl, p<0.05) in the patients with CAD, compared with normal control persons (age over 40 years; Apo-A: 246.3±39.9 mg/dl, Apo-B: 117.9±26.4 mg/dl). 3) The TC/HDL-C ratio and Apo B/A ratio were significantly higher (4.9±1.6, 0.67±0.17, p<0.005 for TC/HDL-C ratio and p<0.05 for Apo B/A ratio) in the CAD patients compared with normal control persons (age over 40 years; 3.6±1.1, 0.49±0.10). 4) The TC/HDL-C ratio ≥4.0 and Apo B/A ratio ≥0.55 were the good discriminating criteria separating the CAD patients from the normal control persons. 5) In the athletes, the serum triglyceride (TG) was significantly lower (65.7±20.7mg/dl, p<0.001), and the HDL-C was significantly higher (57.8±11.2 mg/dl, p<0.001) compared with normal control persons (age under 30 years; TG; 119.8±94.3 mg/dl, HDL-C: 44.6±11.0mg/dl). The Apo-A, Apo-B, TC/HDL-C ratio and Apo B/A ratio were all significantly lower (p<0.01) compared with those in the normal control persons. 6) Among the athletes, the HDL-C was highest and the TG was lowest in the swimmers compared with fencing players and wrestlers. The Apo B/A ratio and TC/HD1-C ratio were better discriminating indices of risk factors for CAD compared with individual lipids or apolipoprotein values. The Apo-A and Apo-B were considered to be good indices of risks for CAD. The athletes had lowest risks for CAD.

연구 배경: A. baumannii는 전 세계적으로 중요한 병원 내 병원균으로 부각되고 있고 이들 균에 의한 감염 또한 빠르게 증가하고 있다. 이들 감염에 연관된 사망률(균혈증:52%, 폐렴:23-73%)은 매우 높고 다제 내성은 비교적 흔하게 발생하고 있는 실정이다. 그러므로 다제 내성 A. baumannii 감염에 대한 효과적인 치료를 위해서 이들의 임상 특징과 결과를 분석하고 이해하는 것이 필요하다. 이에 본 연구는 A. baumannii 병원내 폐렴 중 다제 내성군과 약제 감수성군간의 임상적 특징, 사망률, 이환율을 비교하였다. 방법: 2002년 1월 1일부터 2004년 11월 1일까지 춘천성심병원에 입원했던 환자 중 Acinetobacter 병원 내 폐렴으로 판단되는 47명의 환자를 연구 대상으로 하였고 이들의 의무기록을 후향적으로 분석하였다. 본 연구에서는 다제 내성 A. baumannii를 실험 환경에서 A. baumannii에 효과적이며 상업적으로 이용할 수 있는 모든 항생제에 내성을 보이는 것으로 정의하였다. 결과: 47명의 A. baumannii 병원내 폐렴 환자 중 17명이 다제 내성군, 30명이 약제 감수성군으로 분류되었다. 이들의 평균 연령은 다제 내성군은 69±11세, 약제 감수성군 70±13세이었고 APACHE II 점수, 중환자실 입원기간, 사망률에 있어서 두 군간에 유의한 차이는 없었다(16.1±5.4 vs 14.9±4.8, P=0.43, 25.1±13.6 vs 39.1±31.0, P=0.2, 58.8% vs 40%, P=0.21). 결론: Acinetobacter baumannii 다제 내성군과 약제 감수성군 간의 사망률과 임상적 특징 사이에서 유의한 차이는 보이지 않았다. 그러나 양군 모두 사망률과 이환율은 높게 나타나 A. baumannii 감염의 효과적인 감시 및 조절이 지속적으로 필요하겠다. Background: Acinetobacter baumannii has emerged as an important nosocomial pathogen worldwide. The incidence of these infections has recently begun to increase. The mortality rate associated with these infections is high (bacteremia; 52%, pneumonia: 23%~73%) and multidrug resistance has been reported. For the effective control of multidrug-resistant Acinetobacter baumannii(MDR-AB), the impact of these organisms in clinical practice should be determined. This study compared the clinical characteristics, mortality and morbidity of Acinetobacter nosocomial pneumonia between MDR strain and non-MDR strain. Methods: From Jan. 1, 2002 to Nov. 1. 2004, 47 adult patients with Acinetobacter nosocomial pneumonia in Chuncheon Sacred Heart Hospital were recruited and analyzed retrospectively. MDR-AB was defined as showing in vitro resistance to all commercially available antibiotics against A. baumannii. Results: There were 47 patients with Acinetobacter nosocomial pneumonia. MDR-AB and non MDR-AB was the cause of the pneumonia in 17 and 30 patients, respectively. Mean age of the former was 69±11 years old and the latter was 70±13 years old. The mean APCHE II score, ICU days and mortality were not different between the two groups(16.1±5.4 vs. 14.9±4.8, P=0.43, 25.1±13.6 vs. 39.1±31.0, P=0.2, 58.8% vs. 40%, P=0.21). Conclusion: There are no significant differences in mortality and morbidity between MDR and non-MDR Acinetobacter baumannii. The mortality of the two groups is surprisingly high, therefore proper infection control practices are essential. (Tuberc Respir Dis 2006; 61: 13-19)

소의 Extension(E), Agouti(A) 유전자형과 모색유전양상의 연관관계를 이해하기 위해, 한우와 제주흑우(JBC), 이들 사이에서 생산된 교배후손에서 melanocortin-1 receptor( MC1R)과 agouti signaling protein( ASIP)의 유전자형을 분석하였다. 흑모색의 JBC에서는 세 가지 MC1R대립인자들(E<SUP>D</SUP>, E?, e)이 모두 발견되었다. JBC 집단은 한우에서 우점적으로 나타나는 열성동형접합자(e/e)가 발견되지 않았다. 반면, MC1R E?/e한우는 흑모색이 아닌 갈색이나 적색의 모색을 나타내었다. ASIP유전자에서, 한우에서는 L1-BT 전위인자의 삽입/결실에 의해 세 가지 유전자형(A/A, A/A<SUP>Br</SUP>, A<SUP>Br</SUP>/A<SUP>Br</SUP>)이 모두 관찰되었다. JBC 집단에서는 ASIP A<SUP>Br</SUP> 대립인자가 드물게 관찰되고, ASIP A<SUP>Br</SUP>/A<SUP>Br</SUP> 동형접합인 개체들은 발견되지 않았다. ASIP A<SUP>Br</SUP> 대립인자를 보유하더라도 한우와 JBC, 이들의 교배후손에서도 agouti-유사 얼룩무늬 모색은 발견되지 않았다. 교배후손의 모색은 Agouti 유전자형과는 무관하고, Extension유전자형과 직접적으로 연관되어 황-갈색(e/e)과 암-갈/흑색(E?/e)으로만 구분되었다. ASIP유전자형은 아마도 한우 또는 교배 후손에서 모색의 발달에 영향이 없는 것으로 추정된다. 본 연구 결과는 한우, 제주흑우, 이들의 교배후손에서 MC1R유전자형이 모색 표현형을 결정하며, ASIP유전자형은 모색의 변이에는 핵심적인 역할을 수행하지 않는다는 것을 시사한다. To understand the relationship between coat color inheritance patterns and genotypes of Extension( E) and Agouti( A) loci in cattle, the genotypes for melanocortin-1 receptor( MC1R) and agouti signaling protein ( ASIP) were analyzed in Hanwoo, Jeju black cattle (JBC), and their crossbred progeny. Three MC1R alleles ( E<SUP>D</SUP>, E?, and e) were found in the black-colored JBC population. JBC had no recessive homoygotes (e/e), but this genotype was predominant in the Hanwoo breed. However, MC1R E?/eHanwoo did not produce a black coat color as they appeared either as brown or solid red. For ASIP, three genotypes ( A/A, A/A<SUP>Br</SUP>, and A<SUP>Br</SUP>/A<SUP>Br</SUP>) were determined by insertion/deletion of an L1-BT element in Hanwoo. The ASIP A<SUP>Br</SUP> allele was rarely observed, and no ASIP A<SUP>Br</SUP>/A<SUP>Br</SUP> homozygotes were detected in the JBC population. Cattle carrying ASIP ABr did not show any agouti-like brindle pigmentation patterns in either breed or their progeny. The coat colors of the crossbred progeny were discriminated by two colors, yellowish-brown versus dark-brown or black, and their coat colors were directly related to the genotypes of the Extensionlocus, yellowish-brown (e/e) and dark-brown or black (E?/e), but not to the Agouti locus. ASIP genotypes probably did not affect coat color development in the Hanwoo or crossbred progeny. Our results suggest that the ASIP genotypes do not play key roles in coat color variation, but the MC1R genotypes do direct the phenotypes of Hanwoo, JBC, and their progeny.

Purpose: We performed this study to determine how the emergency trauma team affects the treatment of patients with multiple severe trauma and to discuss the effect and the direction of the emergency trauma team`s management. Methods: We performed a retrospective analysis of 518 patients who visited our emergency department with severe trauma from August 2006 to July 2008. We divided the severe trauma patients into 2 groups: patients before and after trauma team management (Group 1 and Group 2). Then, we compared demographic characteristics, mechanisms of injury, and treatment outcomes (lengths of stay in the ED, admission ratio, and in-hospital mortality) between the 2 groups. In the same way, patients with multiple severe trauma were divided into 2 groups, that are patients before and after trauma team management (Group 3 and Group 4) and analyzed. Results: There was no significant difference, except mean age, between groups 1 and 2. In group 4 patients, compared to group 3 patients, the lengths of stay in the ED were lower (p value<0.001), and the admission ratio were higher (p value=0.017), but there was no significant difference in the in-hospital mortality between the groups 3 and 4. Conclusion: When patients with multiple severe trauma visit the ED, the emergency trauma team`s management can decrease the lengths of stay in the ED and increase the admission ratio, but does not produce a decrease in the in-hospital mortality rate. Further investigations of emergency trauma team management are needed to improve treatment outcomes for patients with multiple severe trauma. (J Korean Soc Traumatol 2009;22:172-78)
