The use of critical pathways for a variety of clinical conditions has grown rapidly in recent years, particularly pathways for patients with acute myocardial infarction. We intend to determine the impact of a clinical pathway on ST-elevation myocardial infarction (STEMI) and to evaluate the efficacy and safety of facilitated percutaneous coronary intervention (PCI) compared with primary PCI. Low risk STEMI patients (ST elevation >0.1mV in more than 2 limb leads or ST elevation >0.2mV in contiguous precordial lead, chest pain lasting more than 30 min without response to nitroglycerin) will be included. All patients will be also treated medically according to critical pathway. STEMI is one of the common diseases in emergency medicine and so it is necessary to establish realistic treatment guidelines. The use of critical pathways will improve the quality of care.

This paper presents the fundamental study to implement the wireless data link system in the subway. The propagation characteristics of the electromagnetic wave in the tunnel are analyzed to determine the proper radio frequencies for our system. The tunnel is modeled as a circular waveguide and then, its path loss is obtained. The efficient communication control procedure is proposed, which is well suited to our system architecture and the subway environment. The prototype system shows a good performance in the data communication.

Secondary involvement of the gallbladder by systemic lymphoma is exceedingly rare and relapsed diffuse large B cell lymphoma of the gallbladder has not been reported. A 78-year-old man was admitted to the hospital due to epigastric pain and jaundice. His past medical history was remarkable for diagnosis with diffuse large B-cell lymphoma of the ileum 5 years ago. He underwent right hemicolectomy and three cycles of adjuvant chemotherapy and had complete remission. Abdominal computed tomography showed choledocholithiasis and focal thickening at fundus of the gallbladder. The patient underwent open cholecystectomy. Pathologic examination revealed diffuse large B-cell lymphoma. We report a case of solitary, relapsed diffuse large Bcell lymphoma of the gallbladder with literature review.

Promoter Activity in 5' Non-coding Nucleotides of Babesia equi Merozoite Antigen-1

Sun-Hee Yun,Tae-Hwan Kim,Kyu-Shik Jeong,Oh-Deog Kwon,Gil-Jae Cho,Dong-Mi Kwak 한국실험동물학회 2007 Laboratory Animal Research Vol.23 No.3

Equi merozoite antigen-1 (EMA-1), a 34 kDa surface protein of Babesia equi, is a potential target to block the parasite transmission. While technology for genetic manipulation is not available in B. equi, a functional gene knockout system is established in Plasmodium falciparum using parasite promoters and foreign genes. This research was initiated to identify promoter activity in 5' non-coding nucleotides (770 bp) of ema-1. Escherichia coli transformed with plasmid constructs containing the reporter luciferase gene under control of the B. equi 5' non-coding nucleotides were able to express luciferase, indicating that the ema-1 5' non-coding region has a functional promoter. The activity was detected in both correct and reverse orientations. This information will facilitate further development of a functional knockout system in B. equi.

Objective: The purpose of the present study was to evaluate the effectiveness of the use of Head Posture Aligner (HPA) during cone-beam computed tomography (CBCT) scan in generation of frontal cephalograms using 3D CBCT images. Methods: CBCT scans and frontal cephalograms were made in 30 adult individuals. While a couple of CBCT scan was made for one subject, one was made with conventional method, without use of HPA, the other was acquired with the use of HPA. After creation of virtual frontal cephalogram from each 3D CBCT image, it was traced and compared with the tracing of real frontal cephalogram. Results: In the comparison of the measurements, the virtual cephalograms with the use of HPA did not show statistically significant differences with the real cephalograms whereas the virtual cephalograms without the use of HPA presented significant differences with real cephalograms in many measurements. In the correlation analysis with the measurements of the real cephalograms, the virtual cephalograms with the use of HPA showed higher correlations in all measurements than the virtual cephalograms without the use of HPA. Conclusions: Measurements from CBCT-generated cephalograms become similar to those from real cephalograms with the use of HPA during CBCT scan. Thus, the use of HPA is suggested during the CBCT scan in order to construct accurate virtual frontal cephalograms using 3D CBCT images. 본 연구는 3차원 콘빔CT 영상을 이용하여 2차원 정모두부방사선사진영상 형성 시 두부자세재현기(Head Posture Aligner, HPA)를 이용한 경우와 이용하지 않은 경우를 비교분석함으로써 HPA의 유용성을 평가하기 위하여 시행되었다. 성인 30명을 대상으로 먼저 일반적인 방법으로 콘빔CT 영상을 채득한 후 HPA를 이용하여 일정한 두부자세를 재현한 상태에서 또 하나의 콘빔CT 영상 및 정모두부방사선사진을 촬영하였다. 3차원 영상프로그램을 이용하여 HPA를 이용하지 않은 경우와 HPA를 이용한 경우 각각에서 2차원 정모두부방사선사진영상을 형성한 다음 각각의 투사도를 작성하고 실제로 HPA를 이용하여 촬영된 정모두부방사선사진 투사도와의 차이를 비교하였다. 거리 및 각도를 나타내는 여러 계측치를 비교분석한 결과 HPA를 이용하지 않은 경우에는 다수의 계측항목에서 실제 정모두부방사선사진과 유의한 차이를 보인 반면 HPA를 이용한 경우에는 모든 항목에서 통계적 유의차를 보이지 않았다. 아울러 실제 정모두부방사선사진과의 상관관계를 알아보기 위해 상관분석을 시행한 결과 HPA를 이용한 경우가 그렇지 않은 경우보다 모든 항목에서 높은 상관성을 보였다. 본 연구 결과는 3차원 콘빔CT 영상을 이용하여 2차원 정모두부방사선사진영상 형성 시 정확한 영상 획득을 위해서는 콘빔CT 촬영 시 HPA의 사용이 필요함을 시사하였다.

Objective: To examine the differences in lateral cephalometric characteristics between patients with dental protrusion and crowding in order to determine what factors affect dental protrusion or crowding while both malocclusion types are caused by large tooth size. Methods: Twenty nine individuals with dental protrusion and 22 individuals with dental crowding were enrolled in this study. All subjects had larger teeth than average and Class I molar relationships. Craniofacial characteristics and hyoid bone positions were determined from lateral cephalograms and compared between the two groups. Results: In the comparisons of craniofacial characteristics, the measurements indicating maxillary length and facial convexity showed greater values in the protrusion group than in the crowding group. Comparisons of hyoid bone positions showed that the hyoid bone was positioned more anteriorly and superiorly in the protrusion group than in the crowding group. Conclusions: The results of the present study indicate that some craniofacial characteristics and tongue position may affect the development of dental protrusion or crowding; when an individual has large teeth, dental protrusion or crowding might be determined according to maxillary growth and tongue position. 치아크기가 전반적으로 클 때 어떤 환자에서는 전돌이 나타나는 반면, 어떤 환자에서는 치아밀집 현상이 나타난다. 본 연구는 치아전돌자와 치아밀집자 간의 측모두부방사선규 격사진상의 특징을 비교함으로써 치아전돌 또는 치아밀집 발생 원인을 규명하기 위하여 시행되었다. 치아크기가 정상에 비하여 크면서 제1급 구치관계를 가지는 치아전돌자 29명, 치아밀집자 22명을 선정한 후 중절치부터 제1대구치까지 치아크기를 비교하는 한편, 측모두부방사선규격사진에서 투사도를 작성하고 골격형태, 설골 및 절치 위치를 나타내는 여러 가지 계측치를 설정하고 치아전돌자와 치아밀집자 양군 간의 비교분석을 시행하였다. 연구 결과 본 연구에서 선정된 치아전돌자와 치아밀집자의 치아크기는 양 군 간에 유의한 차이를 보이지 않았으며, 골격형태를 나타내는 계측항목 중 S-N, A'-Ptm', SNA, ANB, 그리고 facial convexity에서 치아전돌자가 통계적으로 유의한 큰 값을 보였다. 또한 설골의 수직위치를 나타내는 hy-PP와 hy-MP는 치아전돌자에서 통계적으로 더 작게, 설골의 전후방 위치를 나타내는 hy'-Go는 치아전돌자에서 통계적으로 더 크게 나타났다. 이상의 결과는 치아전돌자가 치아밀집자에 비해 골격적으로는 상악전돌 경향을 보이고 설골의 위치는 전방 또는 전상방에 위치하고 있어 이러한 차이가 치아전돌 또는 치아밀집 결정과 관련이 있음을 시사하였다.

The aging properties of cellular plastic insulations(EPS,PUF and UFF) were investigated by varying temperature, relative humidity and time. The time aging properties were changed with in 10 - 12% of initial properties at high temperature(above 318K) and relative humidity (above 90%). The amount of HCHO gas release from UFF was increased as temperature and relative humidity increased, and HCHO release rate was decreased exponentially with time.
