The purpose of the present study is to investigate the lipid peroxidation, creatine kinase activity and cortisol hormone levels following the training intensity in elite judo players. Six elite Judo players participated in the experiments (3h repetition judo program), which include stretching, judo skill practice and cool down without recess. Blood sampling were taken at the judo gymnasium at the time of resting, 1h training, 2h training, 3h training, 2h recovery, and 24h recovery time and this were analyzed for CK, MDA and Cortisol levels. The results obtained were analyzed via repeated measures of ANOVA using SPSS package program (ver.10.0) and a value of p<.05 was considered statistically significant. The results from this study were as follows. In the CK levels, which reflect the contribution of creatine phosphate and muscle damage degree, there was a significant difference (p<.05) after judo training in every period. Recovery 24h showed the highest level. In the MDA levels, which reflect lipid peroxidation, there was a significant difference (p<.05) after judo training. Recovery 2h showed the lowest level. In the cortisol hormone levels, which reflect stress status, there was a significant difference (p<.05). In this study, we can conclude that For the trained athletes, MDA level was lower at the time of exercise compare to the other period, this is caused by the increased antioxidant defence mechanism.
DWP401, a recombinant human epidermal growth factor, was subcutaneously administered to ICR mice at the dose levels of 0, 0.04, 0.2 and 1.0 mg/kg/day (15rats/sex/group) in order to evaluate the subchronic toxicity. General observations, examinations for food and water consumption, ophthalmoscopy and urinalysis were carried out during the study. For the complete gross and microscopic examinations, 10 mice/ sex/group were sacrificed at the ends of the dosing period, and the remaining animals were sacrificed with a 5 week recovery period. Examinations for hematology and blood biochemistry were also carried out at the time of recovery period. Based on the results, it was thought that the target tissue or organs were mesothelial cell, injection site, spleen, adrenal gland, ovary and transitional epithelial cell of urinary tract, and no observed toxic level of DWP401 was 0.04 mg/kg while definite toxic dose level might be 0.2 mg/kg.

Wheat is frequently exposed to high temperature during anthesis and ripening period, which resulted in yield loss and detrimental end-use-quality. The transcriptome analysis of wheat under high temperature stress during the early stage of the grain filling period was undertaken. Three expression patterns of differentially expressed genes (DEGs) during grain filling period were identified. The DEGs of seed storage protein and starch-branching enzyme showed continuous increases in their expressions during high temperature stress, as well as during the recovery period. The activities of the enzymes responsible for the elimination of antioxidants were significantly affected by exposure to high temperature stress. Only the WAS-2 family genes showed increased transcription levels under high temperature stress in dehulled spikelets. The relative transcription levels for sub-genome specific WAS-2 genes suggested that WAS-2 genes reacted with over-expression under high temperature stress and decreased back to normal expression during recovery. We propose the role of WAS-2 as a protective mechanism during the stage of grain development under high temperature in spikelets.
Purpose: Saturday night palsy is a transient form of nerve palsy that occurs after a prolonged period of direct pressure on the course of radial nerve by one's own or spouse's head. Although commonly encountered, there have been only few studies concerning its convalescence. The purpose of this study is to predict the prognosis of Saturday night palsy based on the causes, time to recovery and degree of recovery. Materials and Methods: Retrospective study of 20 patients who were diagnosed compression radial nerve palsy was performed. The average age was 36.7 years old and the mean follow-up period was 19.6 months. We investigated sleeping hours as an indirect measure of nerve compression time, recovery of wrist and finger extension, DASH score on the monthly based follow up. Results: The mean sleeping hours was 5.8 hours and all patients showed full recovery of wrist and fingers extension with the mean duration of symptom for 3.2 months. DASH score was an average 1.53 at the last follow up and we found no statistical significance between the time to recovery and the sleeping hours. Conclusion: Complete natural recovery can be expected in compression radial nerve palsy in this study without correlation with sleeping time. Accurate diagnosis is important in order to avoid unnecessary therapeutic intervention and further study should be accomplished for clarifying the related prognostic factors in larger scale of the cases.
The purpose of this study was to investigate the relationship between the cumulative fatigue of trunk muscles and the period of recovery time during repetitive lifting and lowering task with two different frequencies(4 times/min and 6 times/ min). Eight healthy males with no prior history of LBD(low back disorders) volunteered for this study. Subjects had 2, 3, 4, and 5 minutes recovery time respectively while they were preforming the lifting and lowering task at 15% level of MVC. EMG signals from six trunk muscles were collected and the fatigue level was analyzed quantitatively. In results, the fatigue levels of LES(left elector spinae), RLD(right lattissimus dorsi), LLD(left lattissimus dorsi), RRA(right rectus abdominis) and LRA(left rectus abdominis) were recovered when 3 minutes recovery time was given at 4 times/min frequency. However, the fatgue level of RES(right elector spinae) was recovered when 4 minutes recovery was given. On the other hand, when 6 times/min frequency was used, the RLD, LLD, RRA and LRA were recovered at 5 minutes of recovery time. But for RES and LES, it took longer than 5 minutes to be recovered. This results can be applied to design the adequate length of recovery time to control the cumulative fatigue of trunk muscles in industry with repetitive lifting and lowering task.
Purpose: The aim of study was to investigate relationship between compliance and recovery of patients with osteoarthritis of the knee patients after knee arthroplasty. Methods: 193 patients living in Seoul were participated in this study. Data were collected using the Knee Society Clinical Rating System and Medical Outcomes Study Short Form 36(SF-36) and analyzed by ANCOVA, t-test, and repeated measure ANOVA. Results: There was a significant difference of physiological recovery based on the number of co-morbidity patients have. Physical recovery level was different according to age, religion, and the number of co-morbidity. Age and education level of patients were different in emotional recovery. The level of physiological and physical recovery were significantly different consistent with compliance. Compared to preoperative scores, physiological and physical scores showed significant improvement at six weeks, three months, and six months after surgery while emotional scores did not showed significant improvement. Conclusion: The results of this study suggest that nursing interventions to increase compliance are needed for better recovery of patients after knee arthroplasty.

This study was carried out to investigate the effects of diet of Korean safflower(Carthamus tinctorious L.) seed powder on bone tissue during the recovery of rib-fracture in rats. Male Sprague-Dawley rats of 10 weeks old, weighing 370$\pm$5g, were divided into two groups including the control group(C group, AIN-76 semipurified diet) and safflower seed group(S group, AIN-76 semipurified diet+10% safflower seed powder) and were fed experimental diets for 12 days after adaptation period. After this period, the 9th right rib was fractured surgically and sham-operation was also performed. Rats were fed with experimental diets for up to 30 more days after rib-fracture. The degree of bone repair was evaluated during the recovery period at the 8th, 11th, 16th, 21st, 30th days after the surgical operation by microscopic observation of the fractured rib tissue. In callus formation, the portion of hyaline cartilage was noticably higher in S group than C group. The intracatilagenous ossification was observed at the 8th day in S group, but at 11th day in C group. The intramembranous ossification in callus was widely found over the 8th day to the 11th day in S group, but it was shown over the 11th day to the 16th day in C group. Bone resorption was also occured more rapidly in S group as indicated by large numbers of osteoclasts observed. At the 30th day, most of trabecular bones were disappeared in S group, whereas still shwon in C group over wide ranges of fractured ribs. These results imply that the supplementation of Korean safflower seed powder influences in the recovery of bone fracture by accelerating the process of bone repair.
The purpose of this study is to observe the administering of analgesics and sedatives to cases of surgery, the influence of the patients'situational variables on the use of these drugs, and the required number of recovery days in relation to the patients'situational variables and general conditions. Fifty patients in the age range of 15 through 65 who had undergone general surgery at Seoul national University Hospital. Woo Sok University Hospital and Koryo Hospital between May and August of 1971 were chosen for this study. They were observed with regard to the frequency of postoperative uses of analgesics and sedatives age, the required period of recovery in comparison with the situational variables of patients such as sex, age, marital status, the type and duration of anesthesia, experience of previous operation, history of other diseases, preoperative period of hospitalizations and the general conditions of patients such as sleep, stomach condition, bowel condition, urination, interest in surroundings, strength and energy, self-assistance and appetite. The study results were reviewed in a statistical method to obtain the following findings: 1. There was a significant decrease in the frequency of analgesic uses according to the number of days passed after operation. 2. The mean postoperative recovery days were 5.31 days and mote than half of the patients have never used analgesics until recovery. 3. There was a significant decrease in the frequency of sedative uses according to the number of days passed after operation. 4. The rank-order correlation between the frequency of analgesic use and that of sedative use following surgery observes in relation to the number of postoperative days was a low and negative one. 5. All of the patients except one hate used sedatives only once a day for the whole recovery period. 6. The longer they stayed in the hospital before surgery, the less have they used analgesics after surgery. 7. There were significant differences in use of analgesics after surgery by age groups; the 25-44 age group used more analgesics than the 15-24 and 45-65 age groups. 8. There were no significant differences in use of analgesics after surgery by all situational variables except the number of days of hospitalization and age. 9. The longer they stayed in the hospital before surgery, the earlier have they recovered from the surgery. 10. There were no significant differences in the number of required recovery days by all situational variables except the length of preoperative hospitalization. 11. There were no significant differences in the number of required postoperative recordedly days by the general conditions of patients.
To determine the period and degree of full recovery of postoperative pulmonary function, the author performed seiral pulmonry function test with spirometry at preoperative period and 1st, 2nd, 3rd, 4th, 6th and 8th postoperative week in 64 patients who underwent chest surgery form 1990. 1. to 1990. 8. at Dep. of Thoracic & Cardiovascular surgery, Pusan National University Hospitcal, Pusan, Korea 28 patients underwent lung resection[Group A], 14 patients mediastinal and other thoracic surgery[Group B], and 22 patients heart surgery with cardiopulmonary bypass[Group C]. Al of them recovered normally and discharged without any complications. Their serial changes of pulmonary function test were compaired and its results was as follows; l. Over all mean recovery time of restrictive ventilatory function tests[ie, VC, ERV, IC, FEF1, FVC, FEF200-1200, MVV] were 4th & 6th postoperative week, and that of obstructive ventilatory function tests[ie., EFE25-75%, Vmax50] were 2nd postoperative week. 2. In patient who underwent lung resection surgery[Group A], FEF1 recovered in 4th~6th postoperative week and its ratio to preoperative value was 70% in pneumonectomy, and 75% in lobectomy. FVC recovered in 4th~6th postoperative week and its ratio to preoperative value was 65% in pneumonectomy, and 80% in lobectomy. MVV was recovered in 4th~8th postoperative week and recovery ratio was 80%, FEF200-1200 was recovered at 4th~6th postoperative week and its recovery ratio was 70%, FEF25-75% and Vmax50 was recovered in 2nd~4th postoperative week and recovered nearly to preoperative level. 3. In patient who underwent mediastinal and other thoracic surgery[Group B], FEV1 and FVC and recovered in 4th~6th postoperative week and the recovery ratio of FVC in blebectomy was 90%. MVV reached preoperative level in 4th~8th postoperative week. FEF200-1200, FEF25-75% and Vmax50 were recovered in 2nd~4th postoperative week and the recovery of FEF25-75% and Vmax50 in blebectomy was prominant. 4. In patient who underwent heart surgery[Group C], FEV1 and FVC were recovered in 4th~6th postoperative week. The recover ratio of FEF25-75% and Vmax50 was delaied to 6th~8th postoperative week From the above results we concluded that the recovery time of posoperative restrictive ventilatory disorder was 4th postoperative week and pulmonary complication would possibly occure during that period. So more intensive observations will be needed.
Objective: Endometritis is a major disease, that causes infertility in cattle, and is usually categorized as clinical or subclinical endometritis (SCE). The nutritional condition during the dry period is important for recovery after the last stage of the lactation period, and for postpartum production and reproduction. This study aimed to clarify the relationship between nutritional and metabolic characteristics in the dry period, and the risk of postpartum SCE. Methods: Multiparous Holstein dairy cows (n = 25, raised in a tied stall) were used. Endometrial cytological analysis was performed around 30 days post-partum, with 5% to 14% polymorphonuclear (PMN) as a cut-off point to define SCE. Serum levels of glucose, non-esterified fatty acids, β-hydroxybutyric acid (BHBA), blood urea nitrogen, total cholesterol, aspartate aminotransferase, γ-glutamyl transpeptidase, calcium, phosphorus, and magnesium were measured in the cows at the dry period to evaluate energy status, protein metabolism, and mineral metabolism. Results: The incidence of SCE in the cows was 60.0% (n = 15/25) and the mean PMN% in postpartum cows diagnosed as SCE was 8.05%±2.6%. Overall, 17 and 8 samples were collected from the cows in the far-off and close-up periods, respectively. The serum concentration of BHBA in the far-off period and serum glucose concentration in the closeup period were correlated with postpartum PMN% (r = 0.62, p<0.01; r = -0.74, p<0.05, respectively). Serum levels of calcium and magnesium in the dry period were associated with the incidence of postpartum SCE (healthy vs SCE cows, p<0.05). Conclusion: Blood levels of glucose, BHBA, calcium, and magnesium in dry periods could be useful parameters for predicting the risk of postpartum SCE. The present study also suggests that management in the close-up period is essential for promoting recovery from calving fatigue.
