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)

The purpose of this thesis was to investigate plato's view of body and soul from the core of his philosophy Idea, and its influences of his physical thoughts. Some important points of plato's physical thoughts were as follows. 1. In contrast to the general concept that Plato was the mere philosopher of metaphysical dualism an regarded the body as inferior to the soul, he compared the baby to thing and the soul to Idea, and suggested an inseparable relations between body and soul. 2. Plato emphasized physical education to achieve his " Ideal state" in which the great citizens and rulers could be brought up. 3. Plato insisted that physical education should go along mental education of the perfect character building and for the first time promoted firmly the position of that to one of two maintenance in the history of the world physical education. 4. On the basis of ideological thought of physical thoughts, Plato regarded physical education as essential in order to bring up the whole man who was harmonized and balanced with in his mind and body. 5. Plato explained physical education in detail from nursing period, infant period, juvenile period to the youth period. 6. Plato regarded the proper ingestim of nutrition along with the exercise as the principle of physical education. 7. Plato demanded to build three Gymnasiums respectively in the city and in the suburbs. cavalry school and even the teacher's houses. And he insisted that the facilities should be always opened for the enough use. In case it could not be fulfilled, he suggested lawful settlements. 8. In the general rules of personnel administration, Plato discoursed on the duty, qualification and organization.
