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 study was to investigate the effect of Paecilomyces japonica mycelia(PJM) on pH, titrable acidity and microbiological quality of Jeungpyun(fermented rice cake). Jeungpyun prepared with 0?7% of PJM stored at 5℃ and 20℃ for 4 weeks and 7 days respectively. Before fermentation of Jeungpyun dough, viable cells of total bacterial counts(TBC), yeasts and lactic acid bacteria(LAB) were 6.0~9.8×10^6, 5.3~9.0×10^(6), 5.4~8.5×10^(6) CFU/g, respectively. During the fermentation of dough, viable cells of TBC, yeasts and LAB increased 0.3~0.4 log cycle and pH was decreased whereas acidity incresed as the progress of fermentation. Total viable cells in Jeungpyun before storage were 5.0×10¹ CFU/g. During storage of Jeungpyun, TBC, yeasts and LAB of control group increased 2.6, 2.4, 2.1 log cycle at 5℃ and 4.8, 4.6, 4.5 log cycle at 20℃, respectively, when reached at maximum level. Major microflora of Jeungpyun was composed of yeasts and LAB during fermentation of dough and storage at 5℃ and 20℃. Addition of PJM, inhibited the growth of microorganisms, the changes of pH and titrable acidity of Jeungpyun during storage at both of 5℃ and 20℃. From these results, the addition of PJM extended the shelf-life of Jeungpyun during storage at 5℃ and 20℃.

This study pursues the problems of plan photogrammetry which is widely used in somatotyping at present, and find out a method which can improve accuracy of measurement on the basis of principles and mechanisms of photography the basic foundation of the photographic analysis methods. As a result, this study proposes a new method which is based on the reference point method and perspective coordinate system. And the test measurement was operated to compare the measurement accuracy of the proposed method and the method based on reference grid screen method and perpendicular coordinate system which is commonly used at present. The result of this test measurement showed that the proposed method has higher accuracy. Two reasons can be pointed out for the improvement of measuring accuracy. The first reason is that the proposed perspective coordinate system reduces the perspective distortion of photography. And second reason is that measuring points can be closely place to the scale and coordinate reference plan of measurement by the proposed reference point method which make possible to place measuring object(or person) at the center of scale and coordinate reference plan by utilizing reference points of measurement in the three dimensional space not on screen.
