This study was conducted to investigate the relation between visual analogue scale and recovery time with type of injury that occur in elite wrestling athletes. The incidence rate of injury was analyzed the Poisson ratio, and the VAS and recovery time according to the type of injury were compared using the one-way ANOVA. In addition, the VAS and recovery time were examine the relationship using the Simple Linear Regression, and statistical significance level was α =.05. Injuries occurred most commonly in the ligament, followed by the muscle, cartilage and tendon.The VAS and recovery time according to the type of injury was statistically significant (p=.001, p=.001, respectively). The VAS and recovery time according to the type of injury was statistically significant (p=.001, p=.001). Also, increase in VAS of 1 point was associated with about 1.89 recovery time. These studies are expected to be useful as basic data for return to sports and safe training.

This study was performed to evaluate the effects of the combination of electroacupuncture (EA) and surgical decompression on paraplegia due to spinal compression in dogs. Ten clinically healthy dogs were assigned into two groups (group A and group B). The one is for the combination of EA and surgical decompression, and the other is for surgical decompression alone. After decompression, neurological function was evaluated daily with modified Tarlov grading system. SEPs were measured as objective evaluation of normal spinal cord function before spinal compression and after neurological recovery. The period of rehabilitation in group A was significantly shorter than that in group B (p<0.05). Conduction velocity of SEPs showed a tendency to return to normal when the dogs got full recovery. According to these results, it was considered that the EA with surgical decompression was more effective than surgical decompression alone for paraplegia resulting from spinal cord injury in dog.

This experiment was carried out to elucidate change of antioxidant enzymes activities subjected to water stresses in soybean plant. In this study, we measured the activities of ascorbate peroxidase(APDX), monodehydroascorbate reductase(MDHAR), dehydroascorbate reductase (DHAR), glutathione reductase(GR) subjected to drought or flooding stresses for 4days and following recovery for 3days. Leaves of two soybean lines subjected to drought or flooding showed premature senescence as evidenced by the decrease in water content and total soluble protein content but those of soybean leaves was increased when stresses were recovered for 3days. The activities of APDX and GR subjected to drought or flooding were the decrease but those of enzymes were recovered when water stress was recovered. The activities of MDHAR with drought or flooding were on the decrease, whereas those of DHAR were increased, respectively. Antioxidant contents decreased continually subjected to drought or flooding but it recovered after 3 days subjected to water stresses.

This study is aimed at analyzing the effectiveness of TAC policy using a bioeconomic model. A surplus-production model is used as a population dynamic model, from which the yellowedge grouper is estimated to be overfished. As a result, a 10-year rebuilding plan using the TAC policy is established. According to the result of model, under the well-enforced system, the target stock biomass is achieved during the rebuilding period. Especially, in order to accomplish the target stock biomass, the annual quota should be allocated much less than 342 tons that NMFS recommended. The NPV over a 25-year under the TAC policy Is predicted to be less than under the status quo. The economic gains under the variable-catch TAC policy is less than under the constant-catch TAC policy as the interest rate decreases, while the NPV under the constant-catch is greater than under the variable-catch TAC policy when the interest rate is high.

Purpose : The purpose of this study is to determine if there are prognostic factors leading to permanent parenchymal damages to kidney in children after acute pyelonephritis. Methods : This study was conducted in 160 pediatric patients with acute pyelonephritis admitted to Ajou University Hospital from 2000 to 2005, whose renal cortical defects were confirmed by $^{99m}Tc$-dimercaptosuccinic acid scintigraphy (DMSA scan). Along with the follow-up DMSA scan after 6 months, they were classified into two groups; recovered group (106) and scarred group (54). The clinical characteristics of each group were compared. Results : Among the total of 160 patients, 106 (66.3%) showed recovery of the initial defect (the recovered group), while 54 (33.8%) showed permanent defects on the followup DMSA scan (scarred group). Recovery rate was poor for patients of 1 year and older, or patients with the duration of fever and pyuria longer than 7 days. The recovery rate was poor in the patients with history of frequent febrile episodes and abnormal results of imaging studies, such as voiding cystourethrography (VCUG), ultrasonography. Conclusion : The recovery rate of children with renal defects on DMSA scan with acute pyelonephritis was lower when the patient is older than 1 year, when the duration of fever and pyuria exceeded 7 days, and when the patients had the histories of frequent febrile episodes and had urinary tract abnormalities on imaging studies. These findings suggest that there may be under- or mis-diagnosis of acute pyelonephritis by pediatrician.

A chilling-tolerant japonica-type and a chilling-susceptible indica-type of rice (Oryza sativa L.) plants were compared with respect to various physiological parameters during chilling and subsequent recovery. The japonica-type and the indica-type of rice cultivars used were Ilpumbyeo and Taebaekbyeo, respectively. The two rice cultivars exhibited little or no differences in the changes of leaf fresh weight and chlorophyll content during chilling at $5^{\circ}C$ for 3 days. During subsequent recovery at $25^{\circ}C$, however, Ilpumbyeo restored its growth more rapidly than Taebaekbyeo. Since the changes of relative water content, malondialdehyde production, an estimate of lipid peroxidation, and chlorophyll fluorescence were significantly different in the two rice cultivars during the chilling and subsequent recovery, they were found to be more sensitive physiological parameters than fresh weight and chlorophyll content. However, the differences in relation to water content, malondialdehyde production, and chlorophyll fluorescence between the two rice cultivars were smaller during chilling than those during subsequent recovery. These results suggest that relative water content, malondialdehyde production, and chlorophyll fluorescence could widely be used as important physiological parameters for screening chilling-tolerant plants.

This study was carried out in order to study early histologic changes and repair reaction appling to extrusive force for 3rd premolar of adult dogs. After 1 week of extrusive force with elastic chain, one of dogs was sacrified and after 3 weeks retention period, another dog was sacrified. The paraffin sections of samples were stained with Hematoxylin - Eosin and Masson's Trichrome and were examed by light microscopy . The obtained results as follows 1. In Hematoxylin - Eosin and Masson Trichrome stain of control group , the periodontal ligament width was constant from apical third to cervical third of the root and periodontal fiber arrangement was horizontal or oblique in cervical third. oblique in middle third, oblique in apical third of root. in alveolar bone, smooth appearance was shown 2. In Group 1, all periodontal fiber arrangement was oblique toward tooth, and the periodontal ligament width increased Partially PDL was ruptured in apex. In MT stain, immature bone formation was seen at alveolar crest area. Active bone formation was observed along the one side of alveolus, and apical portion of pulp was involved with blood vessel rupture , vacuolization of pulp tissue and hyperemia 3. In Group 2, most periodontal ligament arrangement and PDL width was repaired and fiber density increased. In MT stain, mineralization of immature bone on the alveolar crest was progressed. In pulp, vacuole and hyperemia was diminished and fibrotic change was diminished 4. After 3 week periodontal ligament has more repair ability than pulp tissue. pulp was involved with vacuolization and fibrosis, so it takes more time for repair.

Purpose : The purpose of this study was to evaluate factors affecting hematologic recovery and infection in high-dose chemotherapy(HDCT) and autologous stem cell transplantation(ASCT) in patients with high-risk solid tumor. Methods : From January 2004 to December 2005, 72 HDCTs and ASCTs were applied to children with high-risk solid tumor at Samsung Medical Center. Medical records of these 72 HDCTs and ASCTs were retrospectively analyzed. Results : The single most powerful predictor of neutrophil and platelet recovery was the number of transplanted $CD34^+$ cells. The duration of high fever was significantly longer in young patients, in patients treated with total body irradiation and/or thiotepa, and in patients transplanted with lower $CD34^+$ cell dose(<$2{\times}10^6/kg$). However, the difference in the duration of high fever according to the number of $CD34^+$ cells was not clinically significant. Conclusion : Findings in this study suggest that HDCT and ASCT with low $CD34^+$ cell dose is clinically feasible despite delayed hematologic recovery, especially at a dose >$1{\times}10^6/kg$ per transplantation. Therefore, it is important not to defer the appropriate time for HDCT for an additional collection of hematopoietic stem cells if the number of collected $CD34^+$ cells is >$1{\times}10^6/kg$ per transplantation.
