  • Objectives : The present study has been undertaken to investigate the effects of Polygoni Multiflori Radix and Polygoni Multiflori Radix Preparat on prevention of osteoporosis in ovariectomized rats. Method : In this experiment, the rats were ovariectomized. Rats were administered by 2 kinds of medicine, Polygoni Multiflori Radix and Polygoni Multiflori Radix Preparat. Results : The levels of spinal bone mineral density was significantly increased in comparison with OVX group at 6 weeks in Polygoni Multiflori Radix Preparat group. The levels of serum osteoclacin and calcium didn't show significant changes in comparison with OVX group in Polygoni Multiflori Radix and Polygoni Multiflori Radix Preparat group. The levels of serum ALP showed significant decrease in comparison with OVX group at 3 weeks in Polygoni Multiflori Radix group, and showed significant decrease in comparison with OVX group at 6 weeks in Polygoni Multiflori Radix Preparat group. The levels of serum phosphorus showed significant decrease in comparison with OVX group at 3, 6 weeks in Polygoni Multiflori Radix, and showed significant decrease in comparison with OVX group at 6 weeks in Polygoni Multiflori Radix Preparat group. The levels of urine calcium and phosphorus didn't show significant changes in comparison with OVX group in Polygoni Multiflori Radix and Polygoni Multiflori Radix Preparat group. The levels of femoral and fibula-tibial calcium showed significant increase in comparison with OVX group in Polygoni Multiflori Radix and Polygoni Multiflori Radix Preparat group. The levels of femoral phosphorus showed significant increase in comparison with OVX group in Polygoni Multiflori Radix and Polygoni Multiflori Radix Preparat group. The levels of femoral and fibula-tibial ash weight showed significant increase in comparison with OVX group in Polygoni Multiflori Radix Preparat group. And the levels of fibula-tibial ash weight showed significant increase in comparison with OVX group in Polygoni Multiflori Radix group. The levels of body weight and uterus weight didn't show significant changes in comparison with OVX group in Polygoni Multiflon Radix and Polygoni Multiflori Radix Preparat group. Conclusion : Reviewing these experimetal results, it appears that Polygoni Multiflori Radix and Polygoni Multiflori Radix Preparat have efficacy on prevention of osteoporosis.

  • Objective : We investigated whether Disability Evaluation (DE) situations influence patients' neuropsychological test performances and psychopathological characteristics and which variable play a role to establish an explanation model using statistical analysis. Methods : Patients were 536 (56.6%) brain-injured persons who met inclusion and exclusion criteria, classified into the DE group (DE; n = 300, 56.0%) and the non-DE group (NDE; n = 236, 44.0%) according to the neuropsychological testing's purpose. Next, we classified DE subjects into DE cluster 1 (DEC1; 91, 17.0%), DE cluster 2 (DEC2; 125; 23.3%), and DE cluster 3 (DEC3; 84, 15.7%) via two-step cluster analysis, to specify DE characteristics. All patients completed the K-WAIS, K-MAS, K-BNT, SCL-90-R, and MMPI. Results : In comparisons between DE and NDE, the DE group showed lower intelligence quotients and more severe psychopathologic symptoms, as evaluated by the SCL-90-R and MMPI, than the NDE group did. When comparing the intelligence among the DE groups and NDE group, DEC1 group performed worst on intelligence and memory and had most severe psychopathologic symptoms than the NDE group did. The DEC2 group showed modest performance increase over the DEC1 and DEC3, similar to the NDE group. Paradoxically, the DEC3 group performed better than the NDE group did on all variables. Conclusion : The DE group showed minimal "faking bad" patterns. When we divided the DE group into three groups, the DEC1 group showed typical malingering patterns, the DEC2 group showed passive malingering patterns, and the DEC3 group suggested denial of symptoms and resistance to treatment.

  • Purpose: The purpose of this study was to evaluate the impact of differences in computer-aided cognitive rehabilitation aimed at stroke patients on cognitive function and daily life. Methods: The study subjects were Gwangju, Jeonnam including the attention group (group I), memory group (group II), and visual perception group (group III), who were randomly placed in each of a 10 by one problem solving group (group IV). The PSSCogRehab was applied to all subjects who underwent eight weeks once a week after 20 minutes in each group by strengthening mediation 10 minutes 30 minutes total, with a five minute break in the middle. Results: Cognitive function and activities of daily living is security and inter-group differences before intervention, and post-test results in the memory training group II, the intervention group I, III, IV and more on cognitive function and activities of daily living compared to it was effective. Conclusion: The results of computer-aided cognitive rehabilitation measuring cognitive function and ADL in patients with stroke in accordance with the group I, III, and IV group cognitive function and activities of daily living compared to IV showed that it was more effective.

  • The purpose of this study was to evaluate the most effective method for repairing the exfoliated resin teeth. The specimens were divided into five groups according to repair method and presence of retention holes. The groups were as follows Group1 : Control group Group2 : Sprinkle method with no retention holes Group3 : Sprinkle method with retention holes Group4 : Flask method with no retention holes Group5 : Flask method with retention holes The results were as follows. 1. According to shear bond strength, the value decreased in the order of group1, group5, group3, group2, group4 and there were significant difference between, each group except between group1 and groups5, group2 and group3, group2 and group4(p < 0.05). 2. According to observations of the exfoliation surface, group2 and 4 showed more failure in the denture base resin and repair resin interface, but in group1, 3 and 5 there were more mixed failures. From the results above, there were no significant difference between repair methods without retention holes. But when comparing groups with retention holes, the flask method showed significantly improved results compared to the sprinkle method. Especially, group5 showed similar results as the control group.

  • It was recognized that lead intoxication reduces thiamine content in the brain of rat and this change produces the alterations of thiamine-related biochemical reactions. In the present study, it was tested whether the changes of myelin composition as well as seizure threshold induced by lead intoxication in rats may be related to these changes of thiamine status and thiamine related biochemical factors. Wistar rats were divided into five groups: Control group, Lead-treated group, Lead plus Thiamine-treated group, Thiamine-deficient group, Pyrithiamine-treated group. Each group was divided into three subgroups: 3, 7 and 16 week old group. Myelin protein and phospholipid, one of the compositions of myelin lipid, were measured in the myelin isolated from rat brain. Threshold of electric shock seizure was tested in each group. The amount of each myelin composition in lead-treated group and thiamine-deficient group was significantly lower than those of all the brains in control group, but recovery by supplementation with thiamine during lead intoxication was occurred only in the cerebellum of 3 week old animal. Thresholds of the electric shock seizure of lead treated group and thiamine deficient group in 3 and 7 week old rats were significantly lower than those of control group, while those of lead plus thiamine treated group were similar to those of control group.
