The purpose of this study was to test the effectiveness of self-management relaxation training through biofeedback and progressive muscle relaxation methods. The effectiveness of the experimental methods was tested by measuring the degree of symptoms of stress(SOS), the McNair's profile of Mood STates(POMS), the levels of ephinephrine, norepinephrine, pulse rate, blood pressure and natural killer cells. The subjects of this study were sixty six nursing students divided into four groups two groups were the biofeedback and progressive muscle relaxation groups, the other two groups served as control groups. One was a group of sophomores with no experience at all, the other a junior group without self-management or relaxation training. This study was condicted for eight weeks of clinical practice from April, 26th 1998 to June, 20th 1998. Biofeedback training was done with software developed by J&J company(1-410 form for abdominal respiration training). Progressive muscle relaxation training was done with an audiotape recorded according to Jacobson's Theory. The data were analyzed with frequencies, means, and analysis of cobariance using the SPSS program and the significance level of statistics was 5%. The results of the study are : 1) The importance of clinical practice stress reduction is shown in that the level of symptoms of stress in the experimental groups in clinical practice was higher than in the group receiving only a lecture. 2) The relaxation training methods of biofeeback and progressive muscle relaxation were effective in reducing the symptoms of stress under the clinical practice stress conditions. 3) The effectiveness of the biofeedback training relaxation method to reduce symptoms of stress was higher than that of progressive muscle relaxation. 4) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in reducing stressful mood states. 5) The relaxation training methods of bioffedback and progressive muscle relaxation were not effective in reducing epinephrine and norepinephrine levels. 6) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in increasing the number of natural killer cells. 7) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in decreasing high systolic and diastolic values of blood pressure and high pulse rates. In summary, the relaxation methods of biofeedback and progressive muscle relaxation in reducing clinical practice stress were effective in lowering the level of symptoms of stress and the profile of stressful mood states. They were also effective in lowering high blood pressure and pulse rates. The relaxation methods were effective in increasing the number of natural killer cells as part of the immune function. However, relaxation methods were not effective symptoms of stress was more effective than the progressive muscle relaxation method.

The myocardial infarction is usually associated with the coronary artery disease in adults. It is unusual in chilhood and young adult but occasionally associated with coronary vasculitis. Takayasu's arteritis produces a panaortits with thickening of the adventitia and narrowing of aorta. Narrowing of coronary arteries is due to extension into these arteries of the processes of inflammation that occur in aorta. We report here two cases of Takayasu's aortitis causing acute myocardial infarction. Case 1 is a 17-year-old girl presented with the inferior myocardial infarction and the cerebral infarction. Digital subtraction aortography showed a diffuse narrowing of the aorta and the obstruction of both subclavian arteritis, right carotid artery and both femoral arteries. Case 2 is a 19-year-old male patient with anterior myocardial infarction. Coronary cineangiogram showed the beak like appearance of the left main coronay artery.

Introduction: Anesthesiologists have been aware of the dangers of diffusion hypoxia in the early postoperative period after nitrous oxide anesthesia, but it was suggested of a little clinical significance in healthy patients. Goal of this study is to re-evaluate the possibility of diffusion hypoxia. METHODS: Eighty patients who were scheduled for vitrectomy were allocated to two groups by normal and abnormal chest X-ray findings and each group was divided into two subgroups by N2O concentration (1-a, 2-a; 50%, 1-b, 2-b; 60%). One and half hours after anesthesia, end-tidal alveolar concentration of oxygen (et-O2), N2O (et-N2O), and PaO2 were measured for 10 minutes after the inspired gases were changed to room air 2 L/minute with controlled ventilation in group 1-a. Those parameters were re-measured after re-administration of O2 and N2O of 50% of each for an hour and the inpired gases were changed to room air again. RESULTS: In group 1-a, there was no significant differences of et-N2O and PaO2 after 5 minutes by air flow. And there was no differences of et-N2O and PaO2 between group 1-a and 1-b by et-N2O after 4 minutes. In group 1-b, PaO2 was in normal range at 10 minutes after, although et-O2 was decreased to 14.9%. However, group 2-b showed peripheral arterial saturation lower than 96% after 6 minutes and mild hypoxemia (PaO2 75.3 mmHg) at 10 minutes. CONCLUSIONS: We suggest that hypoxemic episode during spontaneous breathing of room air in early postoperative period after nitrous oxide anesthesia may be occur due to decreased ventilatory function rather than diffusion of nitrous oxide. However, in patients with minimal abnormal chest X-ray findings even without clinical symptoms, it would be better to avoid high concentration of nitrous oxide.

PURPOSE: To determine whether transpupillary thermotherapy can achieve significant efficacy in maintaining vision without significant adverse effects when used to treat age-related macular degeneration associated with choroidal neovascularization. METHODS: Retrospective chart reviews were made for 33 eyes of 32 patients diagnosed with age-related macular degeneration, and who had received transpupillary thermotherapy due to the development of choroidal neovascularization. Transpupillary thermotherapy was performed 1.4 times on average. RESULTS: Three months after the final therapy, 6 eyes (18%) showed improved vision, 11 eyes (34%) showed no change in vision, and 16 eyes (48%) showed worsening of vision. Of the 21 eyes of 21 patients who were available for optical coherence tomography before and after transpupillary thermotherapy, 19 eyes (90.5%) showed reduced macula thickness, and fundus photographs taken during the latest hospital visit revealed 11 eyes showing fibrosis. CONCLUSIONS: Although it negatively influences subretinal fluid absorption, transpupillary thermotherapy is effective in stabilizing choroidal neovascularization and improving visual accuracy in a short period of time. Thus, further study is warranted.

A 46-year-old female was admitted to Soon Chun Hyang University hospital with a complaint of intermittent epigastric pain. X-ray and endoscopic pictures showed diffase irregular shallow depression which is similar to the macroscopic pattern of the type IIc early gastric cancer. But endoseopic biopsy showed no malignant cell infiltration. Hndoaeopic biopsy plays an important role in excluding the possibility of carcinoma. But operation shoud be considered inspite of biopsy result because malignant lymphoma ean not be completely ruled out. Histopathologic diagnosis was pseudolymphoma of stomach.
