To diagnose acute myocardial infarction(MI), many cardiac markers have been used in hematologic and biochemical analysis, and many studies have been published for hema-tologic and biochemical analysis associated with human acute MI. However, after occurrence of acute MI, the serial investigation for values in hematologic and bioche-mical analysis including chronic MI has rarely been performed. To observe the change of the serial values in hematologic and biochemical analysis, we induced artificial MI. The left main descending artery(LMDA) of the left coronary artery was ligated during the progression(day 1, 3, 5, 7, 14 and 30) of MI. Total 66 Sprague-Dawley rats were divided into the sham group(n=24, thoracotomy without LMDA ligation) and the experimental(MI) group(n=42, with LMDA ligation). And all individual in each group was sacrified at day 1, 3, 5, 7, 14 and 30 for the hematologic and biochemical analysis. In comparison of hematologic analysis between the sham and MI groups, the mean values of red blood cell(RBCs), hemoglobin and hematocrit(HCT) showed a steady increase. In biochemical analysis, the mean values of glucose, choles-terol, total creatine kinase(CK) and isoenzyme MB, and lactate dehydrogenase(LDH) were increased in all MI groups compared with the sham groups. The results of this study suggest that early hematologic and biochemical mean values occurred after acute MI are similar to those of human acute MI. In conclusion, we could observe the alterations and serial values in hematologic and biochemical analysis to the extent of chronic status after acute MI.

Objective: The purpose of this study was to compare preceptors and new graduate nurses on their perception of preceptor teaching effectiveness. Methods: The participants were 90 new nurses and 90 preceptors who worked in A medical center. The data were collected from July 1 to September 30, 2008. A cross-sectional descriptive survey was done using a structured questionnaire. Results: New nurses' perception (4.07±.44) of the preceptor teaching effectiveness was significantly higher than perception of the preceptors (3.57±.37). Fifty five percent of new graduate nurses reported a lack of coherence in the preceptor's practice guidelines. For 5 causal factors classified on the teaching effectiveness, the factor of 'Professional knowledge and ability' showed the highest score, but 'Interpersonal and communication skill' got lowest score for both group. Preceptors responded that they did not have enough time to teach well because of their heavy workloads. Conclusions: These results suggest that the preceptors need appropriate compensation and education opportunities, and new graduate nurses need consistent education by the teaching professionals. Therefore, it is important to give preceptors full charge of the preceptorship. Also, it will be necessary to develop education programs to enhance interpersonal and communication skill for preceptors and new nurses.

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.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

이 연구는 self-etching primer와 adhesive를 사용하여 법랑질 표면에 교정용 브라켓을 접착할 때 수분과 타액, 그리고 혈액에 의한 오염이 브라켓의 전단결합강도에 어떤 영향을 미치는지 알아보고자 시행되었다. 96개의 발거된 치아를 4개의 군으로 나누어서 self-etching primer와 adhesive를 사용하여 다음의 4가지 방법에 따라 교정용 브라켓을 접착하였다. 첫 번째 군은 치면을 건조시킨 상태에서 부착하였고, 두 번째, 세 번째, 네 번째 군은 각각 증류수, 인공타액, 혈액을 적용한 후 브라켓을 접착하였다. 각 시편의 전단결합강도를 측정하였고 debonding 후에 브라켓과 치아 표면은 stereomicroscope을 사용하여 관찰하였다. 각 군에서 4개씩의 시편을 선택하여 표면처리된 법랑질 표면과 접착계면을 주사전자 현미경으로 관찰하여 다음과 같은 결과를 얻었다. 건조군과 증류수군의 전단결합강도는 각각 15.22 ± 2.86 MPa과 16.20±3.85 MPa로 혈액군의 전단결합강도(12.56 ± 2.94 MPa)보다 높았다(p<0.05). 건조군과 증류수군, 그리고 인공타액군간에는 전단결합강도에 통계적 차이가 없었다(p>0.05). 혈액군은 다른군에 비해서 debonding 후 법랑질 표면에 잔류한 레진의 양이 더 적었다(p<0.05). self-etching primer로 처리된 치면의 주사전자현미경 소견에서 건조군과 증류수군의 치면에서는 인공타액군과 혈액군에 비해서 더욱 뚜렷한 산부식 구조를 볼수 있었다. 이상의 결과로서 self-etching primer/adhesive를 사용한 교정용 브라켓의 접착시 수분이나 타액의 오염은 결합력에 거의 영향을 미치지 않음을 알수 있으며, 혈액으로 오염시에는 결합력에 영향을 미치지만, 임상적으로 유용한 최소 결합강도(5.9-7.8 MPa) 이상을 보이고 있음을 알 수 있었다. The purpose of this study was to investigate the influence of water, saliva, and blood contamination on the bonding strenght of metal brackets with a self-etching primer/adhesive to enamel. Ninety-six extracted human teeth were divided into four groups. The brackets were bonded to enamel with a self- etching primer (3M/Unitek Dental Products, Monorovia, California) according to one of four protocols. The teeth were bonded in a dry condition (group D) or in contamination with distilled water (group W), artificial saliva (group S), or fresh human blood (group B). Shear bond strengths were tested using an Instron Universal testing machine. After debonding, bracket and tooth surfaces were examined with a stereomicroscope. In each group, four samples were selected and examined with a Scanning electron microscope of the prepared enamel surface and resin-enamel interface. The results obtained were summarized as follows: Shear bond strength in group D (15.22 ± 2.86 MPa) and W (16.20 ± 3.85 MPa) were higher than in group B (12.56 ± 2.94 MPa) (p<0.05). There were no statistical differences in the shear bond strengths between groups D, W and S (p>0.05). There was a tendency to have less residual adhesive remaining on the enamel surfaces of group B than group D. The SEM morphology of group D and W showed a more roughened etching pattern than group S and B. Water or saliva contamination on bonding of orthodontic brackets with Transbond plus self etching primer had almost no influence on bond strength. In this study, the blood contaminated group showed the lowest bond strength, but it was above the clinically acceptable bond strength (5.9-7.8 MPa, Reynold, 1975). The results of this study suggest that acceptable clinical bond strengths can be obtained in wet conditions when self-etching adhesives are used.

Objectives : The present study was designed to assess the reliability and validity of Korean version ofFamily Questionnaire (FQ-K), a briefquestionnaire measuring expressed emotion (EE). Methods : A sample of 84 first-order relatives ofschizophrenics completed the FQ-K and the data were analyzed for intemal consistency and factor structure. Additionally non-random subset of participants (n=34) refilled FQ-K after two weeks for test-retest reliability and naturalistic follow-up data of 36 were obtained for any re-hospitalization events to assess predictive validity. Results : Intemal consistency of FQ-K was good (Cronbach's alpha=.819) and pimcipal component factor analysis revealedthe two-factor structure (criticism and emotional overinvolvement) identical to previously reported for the FQ. The FQ-K also showed reasonable test-retest reliability and excellent predictive validity was indicated in that outcome of re-hospitalization was superior for low expressed emotion patients at six-month naturalistic follow-up. Conclusion : The Korean version of FQ Proved to be a reliable and valid instrument measuring expressed emotion in relatives of Korean patients with schizophrenia.
