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.

본 연구의 목적은 glucose leakage test를 이용하여 soft chelating irrigation이 근관 충전의 sealing ability에 미치는 영향을 평가하는 것이다. 발치된 45개의 단근치를 수집하여 치관부를 잘라내 치근이 총 13mm가 되게 하였다. 근관은 K3 NiTi 구동 기구를 사용하여 성형하고 #45/.06 taper까지 확대하였다. 3개의 실험군(n=13)과 2개의 대조군(n=3)으로 나누었다. 실험군은 다음의 세척 방법으로 처리하였다. 1군, 2.5% NaOCl로 세척; 2군, 2.5% NaOCl로 세척 후 17% EDTA로 최종 세척; 3군, 2.5% NaOCl과 15% HEBP 혼합 용액으로 세척, 근관은 gutta-percha와 AH Plus를 사용하여 측방가압으로 충전하였다. , 습도 100%에서 7일 동안 보관하고 glucose leakage model을 이용하여 치관부로부터 치근부 방향의 미세누출을 정량화하였다. 1, 4, 7, 14, 21, 28일 째 누출된 glucose의 농도를 spectrophotometry로 측정하였다. 분석 결과 모든 실험군에서 실험 기간 동안 누출이 증가하는 경향이 있었다. HEBP처리군은 실험 기간 동안 EDTA처리군과 유의한 차이를 보이지 않았다. HEBP처리군은 21일 이후부터 도말층으로 덮인 NaOCl처리군에 비해 유의하게 낮은 누출을 보였다. HEBP로 처리된 상아질은 EDTA로 처리된 상아질과 비슷한 양상의 폐쇄를 보였으나 도말층이 남아있는 상아질보다는 우수한 sealing ability를 나타냈다. 그러므로 약한 킬레이트제인 HEBP는 EDTA의 대안이 될 수 있을 것이다. The purpose of this study was to evaluate the effect of soft chelating irrigant on the sealing ability of root fillings by using a glucose leakage test. A total of 45 single-rooted teeth were selected for the study. The teeth were decoronated leaving a total length of 13mm. The root canals prepared using K3 NiTi rotary instruments to an apical dimension of size 45(0.06 taper). The specimens were then randomly divided into 3 experimental groups of 13 roots each and 2 control groups of 3 roots each. Specimen in each group were prepared with different irrigation protocols : group 1, 2.5% NaOCl; group 2, 2.5% NaOCl and 17% EDTA: group 3, 2.5% NaOCl and 15% HEBP. The root canals were filled with gutta-percha and AH Plus sealer using lateral condensation. After 7 days in , 100% humidity, the coronal-to-apical microleakage was evaluated quantitatively using a glucose leakage model. The leaked glucose concentration was measured with spectrophotometry at 1, 4, 7, 14, 21 and 28 days. There was a tendency of increase in leakage in all experimental groups during experimental period. HEBP-treated dentin showed no significant difference with EDTA-treated dentin during experimental period. From the 21th day onward, HEBP-treated dentin showed significantly lower leakage than smear-covered dentin. HEBP-treated dentin displayed a similar sealing pattern to EDTA-treated dentin and a better sealing ability than smear-covered dentin. Consequently, a soft chelator(HEBP) could be considered as the possible alternative to EDTA.
