Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

Congenital factor VII deficiency is a rare bleeding disorder that has an estimated prevalence of 1/300,000 to 1/500,000. Transmission is autosomal recessive. Because factor VII is important in initiation the coagulation cascade, a factor VII deficiency can result in significant bleeding with pr oiongation of the prothrombin time. In severely affected patients, bleeding starts early in life and encompasses life-threatening hemorrhages such as Intracranial and gastrointestinal hemorrhages. These are the most frequent bleeding events in the first 6 months of life. Definitive diagnosis tests on a specific assay for factor VII clotting activity. Human factor VII from plasma is used to treat factor VII deficiency. Either fresh frozen plasma or factor VII concentrate can be used. We experienced a case of intraventricular hemorrhage in a newborn infant who had been diagnosed as congenital factor VII deficiency. So, we report the case with a review of literatures.

Studies were conducted to find out relationship between the vigor of lettuce and the production of ethylene from germinating seeds of i5 cultivars and lines at 3 different temperatures. The effect of red light illumination and the effect of ACC (1-aminocyclopropane-1-carboxylic acid) and red light on seed germination and ethylene production were also investigated. major results can be summarized a s follows. 1. The lettuce seeds with greater ability of producing ethylene germinated better at high temperatures (25 and 30℃). Highly significant, positive correlations were found between the ethylene evolution and the germination rate at both tested temperatures. 2. Red light treatment significantly increased ethylene evolution and the seed germination rate at 25℃. Treatment of ACC in addition to the red light illumination further increased the germination rate as compared to the red light treatment alone. 3. Red light treatment a t high temperatures was found to be effective in releasing the thermodormancy induced by high temperatures, but the effectiveness varied considerably depending upon the cultivars.

Clinical effects of rhG-CSF were investigated in 17 patients receiving chemotherapy for non-Hodgkin's lymphoma. Patients were given G-CSF 2㎍/㎏/day after 2nd cycle chemotherapy for least 14 consecutive days, and clinical and laboratory results were compared to results of the first cycle. Treatment with G-CSF resulted in increase of mean WBC count(952.9±152.2㎜³vs 1882.4±350.4/㎜³) and neutrophil count(212.9±53.0/㎜³vs 841.5±238.0/㎜³), reduced the duration of leukocytopenic days(12.4±1.3 days vs 5.5±1.0 days, WBC count less than 4000/㎜³) and neutropenic days(4.5±0.9 days vs 2.3±0.7 days, neutrophil count less than 500/㎜³), and reduced the duration of neutropenic fever(5.8±1.1 days vs 0.9±0.5 days). The side effects of G-CSF were not so significant. These results demonstrated that G-CSF is safe and useful for the treatment of neutropenia induced by anticancer chemotherapy of non-Hodgkin's lymphoma and reducing the incidence of febrile periods and duration of antibiotic administration.

배경 : MRSA, VRE, VRSA같은 다제 내성 그람 양성균의 등장에 따라 glycopeptide를 대체할 새로운 항생제의 개발이 필요하게 되었고 결과적으로 새로운 항생제인 linezolid라는 항생제가 개발되었다. Linezolid는 이전의 항생제와는 다른 새로운 계열의 oxazolidinone으로 경구 이용률이 우수하다. 원내 및 원외감염의 중요한 원인균이 되고 있는 MRSA, VRE에 대한 적절한 경구용 항균제가 없는 국내에서 폐렴 및 피부 연조직 감염에서 경구용으로 사용해 볼 수 있는 약제이다. 본 연구에서는 고대 구로 병원에서 분리된 MRSA, VRE 등을 대상으로 다른 여러 항균제와 비교한 linezolid의 시험관내 항균력을 조사하고자 하였다. 재료 및 방법 : 연구대상은 1998년 1월부터 2000년 12월까지 본원에서 입원 및 외래를 통하여 피부 연조직 감염증 및 호흡기 감염증, 요로감염증으로 진단된 환자들의 가검물로부터 분리된 MRSA 60균주, VRE 43균주, PRSP 25균주를 액체배지 또는 한천배지 희석법을 통하여 linezolid 및 기타 항균제에 대한 최소발육억제농도를 구하였다. 결과 : 실험에 사용한 S. aureus는 모두 MRSA였고 이들은 linezolid에 대해 MIC_(90) 2㎍/㎖(MIC 범위 1-2㎍/㎖), Enterococcus spp는 모두 VRE로 linezolid의 MIC_(90)은 2㎍/㎖로 MIC 범위는 1-4㎍/㎖였다. 한 개의 균주에서 MIC 4㎍/㎖로 중등도 감수성을 보였으나 MIC breakpoint가 (8㎍/㎖인 내성균주는 없고 모두 감수성을 보였다. S. pneumoniae의 경우 penicillin 내성이었고, linezolid MIC_(90) 1㎍/㎖ (MIC 범위 0.5-1㎍/㎖)로 전부 감수성을 보였다. 결론 : Linezolid는 MRSA를 위시한 VRE, PRSP 등의 다제 내성 그람 양성균에 대하여 우수한 시험관내 항균력을 보임을 알 수 있었다. Background : The emergence of multi-drug resistant Gram-positive cocci, such as MRSA, VRE, and VRSA, necessitated to develop new antibiotics, which could replace the glycopeptide. As a result, a new antibiotics named linezolid was developed. Linezolid is different line of oxazolidinones with a good oral bioavailability, compared to other antibiotics. Since appropriate oral antibiotics are not presently available for MRSA, which is a major cause of nosocomial and community acquired infections, the introduction of linezolid will have favorable effect on treatment of infections such as pneumonia or skin infections. In this study, we investigated the antibiotic effect of linezolid on MRSA and VRE isolated from patients who were treated in Korea University Guro Hospital. Material and Methods : By using broth microdilution and agar dilution method we measured minimum inhibitory concentration (MIC) with sixty S. aureus, forty three Enterococcus spp., and twenty five S. pneumoniae isolates from patients who were diagnosed as skin, soft tissue, respiratory, and urinary infections in Korea University Guro Hospital from January, 1998 to December, 2002. Results : All of S. aureus used in this study were MRSA, and MIG_(90) of linezolid was below 2 ㎍/㎖ (MIC ranged between 1-2 ㎍/㎖). All of Enterococcus spp. were VRE, and had MIG_(90) of 2 ㎍/㎖ (MIC ranged between 1 to 4 ㎍/㎖). One of the VRE showed intermediate susceptibility with MIC of 4 ㎍/㎖. However, none was resistant with MIC breakpoint above 8 ㎍/㎖. All of S. pneumoniae were resistant to penicillin, but they were susceptible to linezolid with MICao of 1 ㎍/㎖(MIC range 0.5-1㎍/㎖). Conclusion : In conclusions, linezolid has an excellent in vitro antibiotic effect on multi-drug resistant Gram-positive cocci, such as MRSA, PRSP, and VRE.

박능화,신정우,박종호,방성조,김대현,주광로,김도하 대한간학회 2003 Clinical and Molecular Hepatology(대한간학회지) Vol.9 No.4

목적: 라미부딘의 투여기간이 길수록 약제내성 변이형 바이러스의 발생률이 증가하게 된다. 변이형의 장기적인 임상적 의의는 논란이 많다. 본 연구는 B형 간염 바이러스에 의한 만성 간질환자에서 변이형이 생긴 뒤의 임상적 경과와 변이형의 발생을 예측할 수 있는 인자를 알아보고자 하였다. 대상과 방법: 만성 B형 간 질환자로 진단 받은 환자 중 라미부딘 치료도중에 viral breakthrough가 생긴 124명을 대상으로 하였다. 평균 연령은 40세였고 남녀 비는 105:19였다. 치료 전 혈청 평균 ALT치는 223 IU/L, 혈청 평균 AST치는 127 IU/L, 혈청 평균 HBV DNA치 1216 pg/mL, 치료 전 정량적 평균 HBeAg치 259이였다. 라미부딘은 1일 100 ㎎씩 breakthrough가 발생한 124명에게 계속 투여하였으며 1, 2개월 간격으로 간기능 검사, HBeAg, anti HBe, HBV DNA 검사를 시행하였다. 라미부딘 총 평균투여 기간은 30.5개월(범위: 10-59개월)이었으며 breakthrough 후 라미부딘 평균 투여기간은 12.5개월(범위: 1-42개월)이였다. 결과: 라미부딘 투여 환자 519명 중 124명에서 viral breakthrough가 5-41개월 사이에 발생하였으며 누적발생률은 12개월 후 8%, 18개월 후 24%, 24개월 후 36%, 36개월 후 52%였다. Viral breakthrough가 생긴 6개월 이내에 120명에서 혈청 ALT치가 상승하였으나 4명에서는 계속 정상으로 유지되었다. 혈청 ALT치는 대부분 상승한 뒤 5개월 내에 최고치에 도달하였으나 6명에서는 12개월 이후에 최고치에 도달하기도 하였다. ALT치는 72명(65%)에서 치료 전 값 이상으로 상승하였으며, 67명(56%)에서 정상치의 5배 이상, 29예(24%)에서 10배 이상 상승하였다. Breakthrough후에 라미부딘 계속투여로 혈청 ALT치가 정상으로 유지된 경우는 22예(18%)에 불과하였으며 98예는 치료전보다 높게 유지되었고 16예에서는 지속적으로 상승하였다. Breakthrough후의 혈청 ALT치 및 AST치가 치료 전보다 의미 있게 상승하였으나 혈청 HBV DNA치는 차이가 없었다. Breakthrough후에 10명에서 HBeAg의 음전이 있었으나 5예에서는 음전 후에 HBV DNA가 재양전되고 혈청 ALT치가 상승되는 HBeAg 음성 만성 간염형태로 나타났다. Breakthrough와 관련된 예측자로 치료 중 정량적 HBeAg의 변화양상만이 유일하게 의미가 있어 감소 후 증가군 82.5%에서,. 지속적 유지군 23.7%에서 Breakthrough가 발생하였으나 지속적 감소군에서는 단지 3.5%만이 발생하였다. 또한 감소 후 증가군에서 정량적 HBeAg치의 감소 후 재상승시점은 약물투여후 평균 9개월로 HBV DNA가 재양전되는 평균시점인 16개월보다 의미 있게 짧았다. Breakthrough후에 투약을 중지한 예는 40예(33%)였다. 이 중 11예에서 중단전보다 혈청 ALT치가 상승되었으며 8개월 내에 전예에서 발생하였다. 중단시 혈청 ALT치가 치료 전 수치보다 높은 경우에서 중단한 26예 중 25명은 중단 후에 혈청 ALT치가 중단 시보다 낮았지만 치료 전 수치보다 낮은 경우에서 중단한 14명 중 10예에서 중단 후에 중단 시보다 더 높아졌다. 결론: 만성 B형 간염환자에서 라미부딘 투여 중에 발생한 HBeAg후의 임상양상은 상당수에서 급성악화를 보였다. Breakthrough를 예측할 수 있는 인자로는 치료 중 정량적 HBeAg치의 변화양상만이 유일한 인자였으며 HBeAg치가 지속적 감소 후에 다시 증가하는 양상을 보인 경우에는 HBV DNA의 재양전보다 더 빨리 Breakthrough을 예측할 수 있었다. Background/Aims: Long-term treatment with lamivudine causes breakthrough, but the clinical course after lamivudine breakthrough is not well known. The aims of this study were to evaluate the clinical course in lamivudine after breakthrough, and to identify predictive factors of breakthrough. Methods: 124 patients with chronic hepatitis B infection, who represented viral breakthrough during lamivudine therapy, were included. The mean duration of lamivudine therapy and additional lamivudine therapy after breakthrough was 30.5 months and 12.5 months, respectively. Results: The cumulative breakthrough rates at 12, 18, 24 and 36 months were 8, 24, 36 and 52%, respectively. After viral breakthrough, only 4 patients maintained normal ALT levels. 120 patients showed ALT elevation. The number of patients with ALT levels greater than 5 times, and greater than 10 times, the upper normal limit were 67(56%) and 29 (24%), respectively. While still on lamivudine therapy after breakthrough, 98 patients presented ALT elevation. Only 22 had normalized ALT levels. Hepatic decompensation developed in 2 patients. HBeAg seroconversion after breakthrough occurred in 10 patients. The changing pattern of quantitative HBeAg levels during lamivudine therapy was the only predictive factor associated with viral breakthrough. The mean time of turning points in decrescendo-crescendo patterns of HBeAg levels during lamivudine therapy was earlier than viral breakthrough (9 months vs. 17 months). Conclusions: These results suggested that deterioration of hepatic function can usually be observed after breakthrough. The serial monitoring of serum quantitative HBeAg levels may allow an early recognition of viral breakthrough.(Korean J Hepatol 2003;9:293-303)
