Background: Retrograde cardioplegia catheter (RCC) insertion is one of methods for administration of cardioplegics during cardiopulmonary bypass (CPB). However its success rate depends on only surgeon's experience. We thought the transesophageal echocardiography (TEE) can guide the R CC insertion, because TEE is commonly used for monitoring status of heart during cardiac surgery. This study was designed to evaluate the RC C insertion time by TEE guidance versus conventional method without T EE guidance. Methods: Sixty patients who were scheduled to undergo elective coronary artery bypass graft (CABG) surgery under general anesthesia were divided into groups as follows: group T [RCC insertion into coronary sinus (CS) by TEE guidance, n=30] and group C [RCC insertion into CS by conventional method, n=30]. We recorded the time of insertion of RCC in to CS in two groups. RCC insertion was done by TEE guidance in case that time was over two minutes by conventional methods in group C. Results: The overall time of RCC insertion into CS was 63.8 ± 23.6 seconds in the Group T and 102.3 ±55.7 seconds in the Group C, respectively (p=0.001). There were no complications during RCC into CS by T EE guidance. Conclusions: TEE guidance for RCC insertion into CS is shorten the time of insertion.

아메바성 대장염과 연관된 Henoch-Scho¨nlein Purpura 1예

장재현,원경준,이준,변유미,이재광,김영훈,박찬국,김만우 朝鮮大學校 附設 醫學硏究所 2006 The Medical Journal of Chosun University Vol.31 No.3

Henoch-SchonIein purpura is a common form of vasculitis primarily involving the skin, the gastrointestinal tract, the joints, the kidneys, and the nervous system. The etiological investigations are essential, because triggering factors are found in approximately half the patients such as viral, bacterial and parasitic infections, drugs, toxins, systemic diseases and cancer. But it's the correlation between Henoch-SchonIein purpura and Entamoeba histolytica has been rarely reported. We report a 29-years-old woman with Henoch-SchoIein purpura complicated by the lower gastrointestinal bleeding caused by the amoebic colitis. She complained of cramping abdominal pain, lower extremity purpura and hematochezia. Cysts and trophozoites of Entamoeba histolytica were detected in her stool. Skin biopsy demonstrated the leukocytoclastic vasculitis. She was administered metronidazole 1,500㎎ a day for the treatment of amebic colitis. Her hematochezia was improved, but the abdominal pain and purpura were not. The subsequent corticosteroid therapy improved her symptoms.

폐수처리 중 생물학적 처리에 활용할 수 있는 질소분해 능력을 가진 미생물을 분리하여 동정하고자 경기도내 하천 6지점에서 채취한 시료로부터 50개 균주를 선별하였다. 형태학적, 생화학적 및 배양학적 실험결과 Bergey's mannual of systematic bacteriology의 색인을 통하여 Aeromonas hydrophila로 동정하였다. Aeromonas hydrophila(AH-1). (AH-3), (AH-4), (AH-6) 균이 질산화 능력이 우수하였다. 4개 균주 모두 amoxillin, ampicillin, cephalothin과 ticarcillin에 내성을 나타내었다. 본 실험에서 분리한 .Aeromonas hydrophila의 질산화의 최적조건은 균 농도 1.0×l0exp(6) cells/ml, 배양온도 37℃로 나타났다. For the purpose of the isolation of microorganisms which have the capability of nitrification, we isolated the microorganisms in 6 samples collected from the stream of Kyonggi area. 60 strains were isolated. The selected strain were identified as a Aeromonas hydrophila based on the data obtained from the morphological, biochemical and cultural characteristics defined experiments. Among them Aeromonas hydrophila (AH-1), (AH-3), (AH-4), (AH-6) showed the highest nitrification capability. All isolates were resistant to amoxillin, ampicillin, cephalothin and ticarcillin. Optimum culture conditions of isolates were 37℃ and 1×10exp(8) cells/ml for 4 hours in the nitrate medium.

근관 내 불규칙 확장부에서 sealer 적용방법에 따른 충전 효과 평가

김성용,이미정,문장원,이세준,유미경 大韓齒科保存學會 2005 Restorative Dentistry & Endodontics Vol.30 No.1

본 실험은 resin 시편을 이용하여 미리 제작한 근관 내 불규칙 확장부에서 근관 충전용 sealer의 적용 방법에 따른 충전 효과를 평가해 보았다. Endo-training Bloc을 절단하여 사십 개의 규격화된 resin 블록 시편을 획득하였다. 각각의 시편에 $, 08taper GT 파일을 사용하여 근관을 형성하였고 근관에 손상이 가지 않도록 시편을 양분한 후 양분된 시편의 한 쪽 근관 벽에 다양한 근관 내 확장부를 표현하는 구를 형성하였다. 양분된 시편을 결찰하고 절단 부위를 밀봉하였으며 AH26 sealer를 사용하여 단일 cone 충전법으로 근관을 충전하였다. 네 가지의 근관 충전용 sealer의 적용방법을 이용하였다: A군,$ K-file : B군, ultrasonic file : C군, lentulo spiral: D군. EZ-Fill bi-directioanl spiral. 모든 시편은 37˚상대습도에서 1주일간 보관한 후 각 시편을 근단에서 3mm, 4mm, 5mm 부위에서 수평으로 절단하고 각각의 절단면을 위상차현미경과 디지털 카메라를 이용하여 30배율로 관찰하고 촬영하였다. 관찰된 절단면은 scoring system을 이용하여 점수를 산정하였고 각 군 간의 통계적인 유의성 유무는 Fisher's Exact Test를 이용하여 시행하였다. The aim of this study was to evaluate the effectiveness of sealer placement in simulated root canal extensions. Forty resin blocks were attained from the Endo-training Bloc. In each block. The simulated root canal was made with $, 80taper GT file. After each block was longitudinally split into two halves, a standardized groove was prepared on one canal wall of two halves to simulate the canal extensions with various irregularities. The two halves of each block were assembled and all simulated root canals were obturated by single cone method with AH26 sealer. Four different methods of sealer placement were used: group A, $ K-file; group B, ultrasonic file; group C, lentulo spiral; group D, EZ-Fill bi-directional spiral. All obturated blocks were stored in 100% humidity at 37℃ for 1 week, Using a low speed saw, each block was sectioned horizontally. Images of the sections were taken using a stereomicroscope at 30 magnification and a digital camera. The amount of the sealer in the groove was evaluated using a scoring system, a higher score indicated better sealing effectiveness. The data was statistically analysed by Fisher's Exact Test. The sealing score was the lowest, specially at the middle area of canal extensions in group A, and that was statistically significant difference from other groups. In conclusion, the ultrasonic file, lentulo spiral and EZ-Fill bi-directional spiral were effective methods of sealer placement in simulated canal extensions. The K file was the least effective method, specially at the middle area of canal extensions.

Characterization of a Membrane Interface for Analysis of Air Samples Using Time-of-flight Mass Spectrometry

Jang, Yu-Mi,Oh, Jun-Sik,Park, Chang-Joon,Yang, Sang-Sik,Jung, Kwang-Woo Korean Chemical Society 2010 Bulletin of the Korean Chemical Society Vol.31 No.10

In the present study, we constructed a membrane inlet assembly for selective permeation of volatile airborne organic compounds for subsequent analysis by time-of-flight mass spectrometry. The time-dependent diffusion of analytes through a $75\;{\mu}m$ thick polydimethylsiloxane membrane was measured by monitoring the ion signal after a step change in the sample concentration. The results fit well to a non-steady-state permeation equation. The diffusion coefficient, response time, and sensitivity were determined experimentally for a range of polar (halogenated) and nonpolar (aromatic) compounds. We found that the response times for several volatile organic compounds were greatly influenced by the alkyl chain length as well as the size of the substituted halogen atoms. The detection limits for benzene, ethylbenzene, and 2-propanol were 0.2 ppm, 0.1 ppm, and 3.0 ppm by volume, respectively, with a linear dynamic range greater than three orders of magnitude. These results indicate that the membrane inlet/time-of-flight mass spectrometry technique will be useful for a wide range of applications, particularly for in situ environmental monitoring.
