N/A Background: Magnetocardiogram (MCG), which records the changes of magnetic fields generated by the heart`s electrical activity, theoritically can provide unique data for clinical application. To date, MCG has been investigated only at a single time point after myocardial infarction (MI) with severe left ventricular dysfunction in rats. The purpose of the present study was to investigate sequential changes of MCG after MI and to evaluate effects of infarct size on MCG. Methods: Acute MI were induced by the permanent ligation of left coronary artery in 22 rats. Magnetic fields were recorded just above a rat with Nb Superconducting Quantum Interference Device (SQUID) gradiometer inside a magnetically shielded room. MCG was measured before and immediately after surgery and it was subsequently recorded at the time points of 1, 4 and 6 hours post operatively. MCG was also measured at 1, 3, 7 and 21 days after surgery. Results: Elevation of ST segment and appearance of pathological Q wave on the MCG were evident immediately after the ligation of coronary artery and persisted to 6 hours after MI. On MCG, ST segment was depressed and T wave was inverted from 1 day after MI. In rats with small-and moderate- sized MI (infarct size〈30%), ST depression returned to near the isoelectric level and Q wave disappeared from 7 days after MI. However, ST depression and Q wave were still present in rats with larger infarct (infarct size≥30%). Conclusion: Evolutional changes of MCG were well-recognized up to 21 days after MI. Furthermore, the infarct size can be expressed by the extent of Q wave and ST segment depression on MCG. Taken together, these data indicate that MCG is a helpful modality for the diagnosis, evaluation of infarct size and follow up after MI.(Korean J Med 62:42-48, 2002)

Drug Information Centers(DICs) are responsible for providing updated and relevant drug information on the efficacy, safety and quality of drugs to health-care practitioners and finally to patients. After the establishment of new prescription law(Bunup)' on August 2000, the future direction for DICs is strongly needed to provide specified, appropriate and rapid information to health-card practitioners and patients. This project was undertaken to provide a future direction of DICs via comparing differences of Q&A before and after Bunup, based on the analysis of Q&A worksheets that were conducted from August 1999 to July 2001 at Drug Information Research Institute(DIRI) of Sookmyung Women's University. In addition, feedback sheets were collected from the users of DIRI from April 2001 to August 2001, to evaluate the satisfaction scores by '5-point Likert scale' on the response. The number of inquiries responded by DIRI was increase from 201 to 574 and the most frequently asked inquirers were pharmacists, specifically community pharmacists. The mean time to respond before and after Bunup was 5.35 and 4.68 hours, respectively. The method of inquiry utilized the most was electronic mailing system followed by telephone both before and after Bunup(66.2% vs. 65.7% via e-mail, from 32.8% vs. 32.4% via telephone). The most frequently asked category of question was on the 'clinical drug' category both before and after Bunup (79% vs. 73.6%). The tertiary literature was the most frequently used reference to answer the inquiries. Mean feedback result via questionnaires was good. That included accuracy, quality of information, time to respond, attitude of provider, accessibility, etc. The most increased inquirer after Bunup was general person, compared with before. Therefore DICs should provide separate responds according to inquirers, develop the systemic program to improve the response for each request, have systemic Q&A worksheet, and develop the educational program for drug information providers. DICs should continuously provide more appropriate and rapid information to health-care practitioners and patients.

혼합 치열기에서 유치의 탈락 및 영구치의 맹출 과정이 순조롭게 이루어지는 것은 중요한 일이다. 맹출 중인 치아는 인접치유무, 유치의 흡수속도, 유치의 조기상실, 만기잔존, 국소병소나 입술, 혀, 저작근 등의 다양한 요인들에 의해 영향 받을 수 있으며, 이러한 요소들 사이의 균형이 깨지게 되면 인접치 간의 관계가 변하고 심각한 부정교합이 초래될 수 있다. 본 증례는 유치열 및 혼합치열을 가진 어린이들에서 상하악 구치부 교합면에 접착된 교합 거상 금속 스플린트(bite raising metal splint)가 치열에 미친 영향에 대해 보여주고 있다. 이들은 스플린트로 인한 유치의 만기잔존으로 영구치 맹출에 방해를 받거나, 전치부 개방교합, 제 1대구치의 저위 맹출 등 혼합 치열기 발달에 큰 영향을 받고 있었다. 치료로써 고속 핸드피스를 이용하여 스플린트를 제거하고 주기적 점검을 통해 교합변화 및 영구치 맹출 양상을 관찰하였다. Children are in mixed dentition during 6 years after 3 years old. this time is very important for sound permanent dentition. There are many factors of influence to tooth eruption stage ; adjacent teeth, tooth resorption, early loss or retention of deciduous tooth, local lesion, lip and tongue, masticatory muscles, ect. These factors should be in balance, if not, relation of adjacent teeth is changed, then severe malocclusion is occurred maybe. These cases revealed influences of resin bonded metal splint on occlusal surface of children's molar to mixed dentition. Splints interfere with falling off of deciduous tooth, tooth eruption, normal occlusion formation, and development of mixed dentition and occlusion. Therefore we removed the metal splint from teeth, follow-up checked occlusion and tooth eruption.

Purpose : The purpose of this study was to investigate factors influencing burden in primary caregivers caring for an elderly person who has had a stroke. Method : A convenience sample of 124 primary caregivers of elderly people with a stroke admitted to an oriental medicine hospital participated in this study. Interviews were done with a standardized questionnaire including Caregiver Burden Scale (Chang, 1995). Result: Average burden score was 93.19, indicating a moderate to severe level of burden. Time-dependent burden had the highest score of the sub-domains. For general characteristics, the factors significantly influencing caregiver burden were gender and age of the elderly person, age and educational level of the caregiver, whether living together or not, and the presence of another caregiver. Multiple regression analyses demonstrated that level of ADL of the elderly person, relationship between the elderly person and the caregiver prior to the stroke, caregivers' relation to the elderly person and primary income were significant factors in explaining variance in overall burden. Conclusion : Recognition of high levels of caregiver burden and factors influencing burden will allow us to develop different nursing strategies to decrease caregiver burden in those caring for an elderly person with a stroke.
