Purpose : The purpose of this study was to evaluate the effects of the Hahoe mask dance on the gait and muscle activity in the elderly who lived at a elderly welfare facility. Methods : Dancing group was consisted of 20 subjects(over 70 years). The time of measurement was assigned in pre measurement, after 1 month, after 2 months. Subjects was received the Hahoe mask dance for three times a week during 8 weeks. The control group was consisted of 20 the elderly (similar age) who didn't received dancing. Assessment of gait function included the gait velocity, step time, stride, step length, it was analyzed in activity for 4 muscles (rectus femoris, biceps femoris, tibialis anterior, and lateral gastrocnemius). Results : Activities for muscles of control group was decreased in rectus femoris, bieps femoris, however, those of experimental group was increased significantly(p<.05). While control group showed decrease in the gait velocity per second (p<.05), experimental group showed statistically significant increase(p<.05). Control group had a significant long time than that of control group in gait time of right and left foot(p<.05). Control group was a little longer than control group in stride time of right and left foot(p<.05). Step length for control group was shorter than that for experimental group both foots(p<.05). Conclusion : In conclusion, this study confirmed that activities for 4 muscles by EMG have showed significant increases, so we will use a programme of muscle improvement in elderly community welfare faculty.

Purpose: This study was to evaluate the effects of a physical activity reinforcement program on exercise compliance, depression, and anxiety in continuous ambulatory peritoneal dialysis(CAPD) patients. Method: A nonequivalent control group with a pre-post test was designed. Data collection was done from December, 2002 to June, 2003 at a hoapital. The degree of depression and anxiety of the patients was assessed by the score of SCL-90-R, and exercise compliance was measured by exercise period, frequency, time and intensity. The experimental group was composed of 19 participants who were educated based on an exercise education protocol and carried out walking exercises two to four times a week after hearing verbal persuasion biweekly through the telephone or a face-to-face interview for 12 weeks, while 17 participants in control group received no intervention. Result: 1. The experimental group showed significant improvement in self-efficacy of exercise compliance (U=79.00, p=.01), exercise period ($x^2$=20.84, p=.00), exercise frequency ($x^2$=9.03, p=.0l), exercise time ($x^2$=9.03, p=.0l) and exercise intensity ($x^2$=11.09, p=.00) compared to those of the control group. 2. The experimental group showed a lower depression score (U=84.50, p=.01) than the results of the control group. 3. However, there were no changes in anxiety level compared to the control group. Conclusion: The physical activity reinforcement program was found to have an effect on exercise compliance and the depression score of CAPD patients. The results provided evidence for the importance of physical activity and verbal persuasion in CAPD patients.

Inflammatory cells may produce active species of oxygen in antimicrobial defense. While such species can directly damage surrounding tissue, their major secondary role may be to mediate important components of the inflammatory response. Superoxide dismutase, antioxidant, have significant anti-inflammatory properties in rheumatoid arthritis, ischemic tissue injury and gastrointestinal disease. Increased oxidative product formation diseases. And superoxide dismutase produced by Porphyromonas Gingivalis is resistant to killing by polymorphonuclear leukocyte. The purpose of this study was to investigate on the effects of superoxide dismutase in 3T3 fibroblast and in experimental gingivitis in the rats. The effect of superoxide dismutase(SOD) to cell morphology and cell activity was measured in cultured mouse 3T3 fibroblast. After experimental gingivitis were induced by lipopolysaccharide(LPb) and bovine serum albumin(BSA), injection of SOD were done. WBC count and histologic findings were observed at 1, 2, 3, and 7 days. The results were as follows; 1. There was a little difference between LPS treated groups and SOD treated groups in 3T3 fibroblast morpholoy. 2. There was no difference between only SOD treated groups (except SOD 150U at 3days) and control in 3T3 fibroblast activity. 3. LPS $0.5{\mu}g/ml$ and SOD treated groups (except 150U) had decreased 3T3 fibroblast activity and no significant difference at 3 days. 4. LPS $5.0{\mu}g/ml$ and SOD treated groups were significantly increased cell activity of 3T3 fibroblast than control group at 1 day(P<0.05). 5. In LPS induced gingivitis, the number of leukocytes in SOD treated was significantly decreased than in saline treated at 1 day(P<0.05). 6. In histopathologic findings of LPS or BSA induced gingivitis, inflammatorycell infiltration in SOD treated groups were less than in saline treated group at 1, 2 and 3 days.

The purpose of this study was to investigate the changes of microsomal mixed function oxidase (MFO) and xanthine oxidase activities (XOD) in the liver of rats exposed to microwave. Sprague-Dawley male rats weighing 200$\pm$10g body weight were randomly assigned to a normal and microwave exposed(MW) groups; microwave exposed groups were divided into two groups; microwave (MW) group and green tea(GT) gropu which were fed distilled water and green tea extracts during experimental periods, respectively. Rats were irradiated with microwave at the frequency of 2.45 GHz for 15min and rats wre sacrificed at the 4th day of the microwave irradiaton. The hemoglobin level of GT group was higher than that of the normal gropu and MW group, but the hematocrit value was not significantly different among all experimental gropus. The activity of serum GOT of MW group was significantly increased but that of GT group was similar to normal group. Activities of GPT were not significantly different among all experimental groups. Liver XOD activity was significantly increased in the microwave exposed groups but green tea normalized the XOD activity. The activity of hepatic microsomal cytochrome P450 was significantly increased in MW group compared to normal group and that of GT group was similar to that of the normal group. The activity of hepatic microsomal NADPH-cytochrome P450 reductase was also significantly increased in MW group compared to normal group, but that of GT group was similar to that fo the normal group. In conclusion, the activities of MFO and XOD were elevated by microwave irradiaton, but the activation of MFO system as well as the damage of the liver by microwave were reduced by green tea supplementation.

Purpose: The purpose of this study was to investigate the effects of upper extremity exercise training on the motor activity, the ADL and the health related quality of life. Method: A non-equivalent pretest-posttest design was used. Study subjects were conveniently selected 40 hemiplegic patients(20 experimental subjects, 20 control subjects) who had been enrolled in two community health centers. After biofeedback training the subjects of experimental group were given constraint-induced movement, involving restraint of unaffected U/E in a sling for about 6 hours over a period of two weeks, while at the same time intensively training the affected U/E. Outcomes were evaluated on the basis of motor activity(amount, quality) of plegic side, ADL(ADL, IADL) and health related QOL(SF-36). Results: 1. After 2 weeks of treatment, the amount of use and the quality of motor activity of affected U/E were significantly higher in subjects who participated in exercise training than in subjects in the control group. 2. There were no significant differences in ADL and IADL between experimental and control groups. 3. After 2 weeks of treatment, the health related QOL was significantly higher in subjects who participated in exercise training than in subjects in the control group. Conclusion: The above results state that the U/E exercise training could be an effective intervention for improving the motor activity and the health related QOL of chronic hemiplegic patients. Long-term studies are needed to determine the lasting effects of constraint-induced movement.

Objectives : This study was designed to investigate the effects of Lumbricus extract(LE) on the regional cerebral blood flow(rCBF) in ischemic rats, further to determine the mechanism of action of LE, and the effects that LE inhibits lactate dehydrogenase(LDH) activity in brain cells. Methods and materials : This study, ischemic rats were divided into total four group: control group(n=6), experimental group I (LE treated group)(n=6), experimental group II(LE treated group after pretreatment with indomethacin)(n=6), experimental group III(LE treated group after pretreatment with methylene blue)(n=6). And the measurement that LE inhibits LDH activity in the damage to brain cells to N-methyl-D-aspartic acid(NMDA). The changes of rCBF were determinated by laser-doppler flowmetry(LDF), and LDH activity was determinated by microplate reader in vitro. Results : 1. The rCBF was significantly improved by LE(10 mg/kg, i.p.) during the period of cerebral reperfusion, compared with the control group. 2. The rCBF was significantly increased by LE after pretreatment with indomethacin(1 mg/kg, i.p.), an inhibitor of cyclooxygenase, during the period of cerebral reperfusion, compared with the LE group, and rCBF was accelerated by LE after pretreatment with methylene blue($10{\mu}g/kg$, i.p.) an inhibitor of guanylate cyclase during the period of cerebral reperfusion, compared with the control group. 3. LE significantly inhibited LDH activity in vitro in a dose-dependent manner. Conclusions : From the above results, these were suggested that Lumbricus had anti-ischemia action in connection with cyclooxygenase and might prevent the brain cells death through inhibited LDH activity.

Purpose : This study aimed to investigate the effect of trunk postural stability maintained wearing a spiral elastic band on the upper extremity function of patients with stroke who undertook a functional activity program and to provide fundamental data useful for the application of therapeutic interventions in the clinical environment of occupational therapy. Methods : The research subjects included 16 patients with stroke who were evenly divided into an experimental group and a control group. The eight-week intervention consisted of a functional activity program aimed at improving the function of the affected-side upper extremity. The experimental group performed the functional activity program while maintaining a stable trunk posture by wearing a spiral elastic band. The control group followed the program without wearing the band. Upper extremity function was assessed before and after the intervention using a manual function test (MFT) and a motor activity log (MAL), and the effectiveness on the upper extremity function of the affected side was confirmed. Results : First, in the within-group comparison of the upper extremity function scores before and after the intervention, the experimental group showed a statistically significant difference in the MFT and MAL assessment(p<.05). The control group showed a statistically significant difference in the MAL assessment(p<.05). Second, in the between-group comparison of the change in scores after the intervention, a statistically significant difference was observed between the two groups in all assessments(p<.05). Conclusion : This study confirmed the positive effect on upper extremity function of trunk stabilization posture using a spiral elastic band. The results could be useful when implementing a task-oriented training program in the clinical environment of occupational therapy in the future, as application of the training while maintaining trunk postural stability by wearing a spiral elastic band could be more effective for improving the upper extremity function of patients with stroke.
