  • Myocardial ischemia causes heterogeneity of ventricular repolarization and sometimes produces changes of the ST-T wave in ECG. Therefore, morphological changes of ST-T waveform in ECG have a clinical significance in diagnosing myocardial ischemia. In this study, we investigated the ST-T changes caused by myocardial ischemia in magnetocardiography (MCG). We analyzed MCG patterns of biphasic T, ST segment deviations from baseline, main current angle of $T_{peak}$ and $T_{peak}$ dispersion in 300 CAD patients without ST elevation in ECG, 122 symptomatic patients and 48 normal subjects. MCGs were recorded by multichannel SQUID system in a magnetically shielded room. As results, we found that appearances of the abnormality were strongly correlated with the severity of myocardial ischemia. Also we found that the percentage of the patients showing MCG changes were higher than those in ECG. These results show that morphological changes of ST-T waveform in MCG can be used as a marker of myocardial ischemia.

  • Objective : Diabetic nephropathy is the most common cause of end stage renal disease. AGE, $TGF-{\beta}1$ type IV collagen, and macrophage/monocyte infiltration are the main factors of diabetic nephropathy. We investigated the effects of Salvia miltiorrhiza on renal function and histopathological changes in streptozotocin(STZ)-induced diabetic nephropathy rat model. Methods : Diabetes was induced in male Sprague-Dawley rats(290${\pm}$10g) by injecting STZ(45mg/kg) into the tail vein. Rats were divided into 3 groups(n = 6): normal, control, and salvia. After 8 weeks of administration of Salvia miltiorrhiza extract on the Salvia group, we checked 24 hrs urine, blood biochemistry and renal tissue to evaluate renal function and histopathological changes by examining parameters including albuminuria, BUN, creatinine, cholesterol, LDL, TG, macrophage/monocyte antigen(ED-1), $TGF-{\beta}1$, AGE, and type IV collagen. Results : Salvia miltiorrhiza decreased the amount of 24hrs proteinuria, and inhibited histopathological changes of diabetic nephropathy including the expression and accumulation of various factors which could promote development of diabetic nephropathy. Conclusion : These findings suggest that Salvia miltiorrhiza might protect the renal function and inhibit the development of renal injury by regulating factors including AGE, $TGF-{\beta}1$ Type IV collagen, macrophage and monocyte infiltration. So Salvia miltiorrhiza can be used for diabetic patients to prevent the progression of diabetic nephropathy.

  • Hepatic encephalopathy is caused by disorders affecting the liver. The exact cause of the disorder is unknown. It occurs changes in mental state, consciousness, behavior, personality and changes in mood include forgetfulness, confusion, disorientation, delirium, dementia, decreased alertness, daytime sleepiness, decreased responsiveness, progressive stupor, coma. As 3 admission patients into oriental hospital of daejeon university include 2 cases of cerebral infarction, 1 case of liver cirrhosis, we found those are all hepatic encephalopathy. But until the diagnosis is made, we have many mistakes to find correct. Among the mistackes, specialy mixed thing is to compare hepatic encephalopathy and cerebral infarction. So, we report these cases with a brief review of related literatures.

  • Purpose: To evaluate the osseous changes of TMJ in internal derangement and osteoarthritis patients using MRI. Materials and Methods: MR images of 111 TMJs in 64 patients were analyzed to evaluate the osseous changes, 111 TMJs were divided into 6 groups according to the radiologic Stages by Schellhas and Wilkes. On MR images, we evaluate the osseous changes of articular eminence and condylar head. Results: The most frequent Stage in internal derangement of TMJ was Stage I. And 28 joints (25.2%) revealed osteoarthritis with internal derangement. When osseous change of articular eminence and condylar head occur, flattening was the most common osseous change. Sclerosis was observed in all Stages and osteophytosis of condylar head was observed in Stage II (1.8%) and III (0.9%). Out of 28 joints with osteoarthritis, 6 joints (21.4%) showed joint effusion. Conclusion: MR image revealed abnormal configuration of disk, but the detection of minimal osseous change was subtle.

  • Ohmic heating uses electric resistance heat which occurs equally and rapidly inside food when the electrical current is transmitted into. Prior to the study, we have researched the potato starch's thermal property changes during ohmic heating. Comparing with conventional heating, the gelatinization temperature and the range of potato starch treated by ohmic heating are increased and narrowed respectively. This result is appeared equally at wheat, corn and sweet potato starch. At this study, we treated potato, wheat, corn and sweet potato starch by ohmic/conventional method and observed change of external structure by microscope and internal structure by X-ray diffractometer. Conventional heated at $55^{\circ}C$ potato starch was not external structural changes. But ohmic heated potato starch is showed largely change. Some small size starch particle were broken or small particles are made of larger particle together or small particles caught up in the large particle. Changes in ohmic heated potato starch at $60^{\circ}C$ was greater. The inner matter came to an external particle burst inside and only the husk has been observed. The same change was observed in the rest of the starch. The change of internal structure of potato starch was measured using X-ray diffraction patterns. There was no significant difference between ohmic and conventional heating at $55^{\circ}C$. But almost every peak has disappeared ohmic at $60^{\circ}C$. Especially $5.4^{\circ}$ peak to represent the type B was completely gone. When viewed from the above results, external changes with change in the internal crystal structure of the starch particles were largely unknown to appear. In conclusion, during ohmic heating changes of starch due to the electric field with a change in temperature by the heating was found to have progressed at the same time.
