植物凝集素 Celosia argentea L. 의 免疫血淸學的 性狀에 關한 硏究

張訓梓 大韓法醫學會 1989 대한법의학회지 Vol.13 No.1

Extracts of ground seeds of Korean Celosia argentea L. were prepared in the usual manner, thereafter the agglutination tests with washed red blood cells and whole blood wee carried out. As a result, author demonstrated that washed red blood cells were markedly agglutinated by C. argentea L. extract, while whole blood was agglutinated in a small number. In the first experiment on a series of 291 blood specimen, washed red blood cells were agglutinated 278 (95.53%), failed 13 (4.47%), while the whole blood was agglutinated 8 (2.75%), failed 283 (97.25%). Since such differences in reactivity were observed, agglutination inhibition test of Celosia extracts by human serum was performed and revealed that by the all sera of 12 of agglutination positive with whole blood, the agglutination of C. argentea L. extracts were completely inhibited, however 429 sera of agglutination negative with whole blood revealed that 414 (96.5%) was inhibitor and 15 (3.5%) was non-inhibitor.

This research has the purpose of finding out the cause of stress which is inflicted on men · women soccer players in high schools. To turn out reliable calculations of average and standard deviation, I used the data collected through questionnaires which are answered by the total number of 472 soccer players(284 men in a high school, 188 women in a high school), and the conclusion was reached with the t-test for statistical verification. Among the cause of stress imposed on soccer players of man's high schools, the most stressful low-factor is when they lost the game, while among woman's high school soccer players, it is when they are despised by the others, and the least stressful factor is the problem with the other sex. The difference of the causes of stress classified by factors reveals that the athletics performance factor is the highest for both the groups of soccer players of women's high schools and colleges. The factor with the most meaningful difference between both the groups of women soccer players is before-competition factor(girl's high school: 2.48±.68, boy's high school: 2.14±1.17), with the meaningful difference at the level of t=-3.64, p<.001, and the rest of the factor don't make any meaningful difference. The stress-mitigating method which soccer players have chosen the most is thinking the matter over and over, but the lowest chosen by them is depending on smoking and drinking. The difference of stress-relieving methods classified by factors demonstrates that the clarification of the causes of stress is the highest factor for both the groups of soccer players. The factor with the most meaningful difference between both the groups is conversation(girl's high school: 2.06±.77, boy's high school: 1.79±.76), with the meaningful difference at the level of t=-3.670, p<.001, and the compensate factor is the next(girl's high school: 2.24±.82, boy's high school: 2.04±.77), with the meaningful difference at the level of t=-2.683, p<.009, and the physical factor is(girl's high school: 2.04±.61, boy's high school: 2.17±.60), with the meaningful difference at the level of t=2.373, p<.018. Therefore, the fact that boy soccer players get much of serious stress from the result of competition tells us that we should be more careful about our words and deeds in the field service. In addition, fear of failure acts greatly as the cause of stress, which requires a preventive alternative through psychological training. Finally, it is thought that it is necessary to make athletics performance ability maximized by making the most of healthy leisure hours.

장재현,원경준,이준,변유미,이재광,김영훈,박찬국,김만우 朝鮮大學校 附設 醫學硏究所 2006 The Medical Journal of Chosun University Vol.31 No.3

Henoch-SchonIein purpura is a common form of vasculitis primarily involving the skin, the gastrointestinal tract, the joints, the kidneys, and the nervous system. The etiological investigations are essential, because triggering factors are found in approximately half the patients such as viral, bacterial and parasitic infections, drugs, toxins, systemic diseases and cancer. But it's the correlation between Henoch-SchonIein purpura and Entamoeba histolytica has been rarely reported. We report a 29-years-old woman with Henoch-SchoIein purpura complicated by the lower gastrointestinal bleeding caused by the amoebic colitis. She complained of cramping abdominal pain, lower extremity purpura and hematochezia. Cysts and trophozoites of Entamoeba histolytica were detected in her stool. Skin biopsy demonstrated the leukocytoclastic vasculitis. She was administered metronidazole 1,500㎎ a day for the treatment of amebic colitis. Her hematochezia was improved, but the abdominal pain and purpura were not. The subsequent corticosteroid therapy improved her symptoms.

This research has the purpose of finding out the cause of stress which is inflicted on the women soccer players belonging to girls' high schools and women's colleges, and examining the different methods of solving their stress. To turn out reliable calculations of average and standard deviation, I used the data collected through questionnaires which are answered by the total number of 266 women soccer players (188 high school players and 78 women's college players), which is followed by the conclusion reached with the t-test for statistical verification, Among the causes of stress imposed on soccer players of the women's high schools and colleges, the most stressful low-factor is the time when they are despised by the others, the least stressful factor is the problem with the other sex. The difference of the causes of stress classified by factors reveals that the athletics performance factor is the highest for both the groups of soccer players of women's high schools and colleges. The factor with the most meaningful difference between both the groups of women soccer players is before-competition factor (girls' high school: 2.49±.69; women's college: 2.27±.72), with the meaningful difference at the level of t=2.38 p <.018, and the rest of the factors don't make any meaningful difference. The low factor of the stress-solving method which soccer players of girls' high schools and women's colleges have chosen the most is thinking the matter over and over, the low factor chosen the least by them is depending on smoking and drinking, and the difference of stress-solving methode classified by factors demonstrates that the clarification of the causes of stress is the highest factor for both the groups of soccer players of girls' high schools and women's colleges. The factor with the most meaningful difference between both the groups of women soccer players is conversation factor (girls' high school: 2.06±.78; women's college: 1.79±.64), with the meaningful difference at the level of t=2.38, p <.006, and the physical factor is the next (girls' high school: 2.04±.61, women's college: 2.25±.62), with the meaningful difference at the level of t=-2.25, p <.011, and the rest of the factors don't make any meaningful difference. Therefore, the fact that women soccer players get much of serious stress from a sense of shame tells us that we should be more careful about our words and deeds in the field service. In addition, fear of failure accts greatly as the cause of stress, which requires a preventive alternative through psychological training, Finally, it is thought that it is necessary to make athletics performance ability maximalized by making the most of healthy leisure hours.

The effects of Pre-exercise BCAA injection on amino acids levels and exercise performance. The subjects of present study were 10 university students. All subjects participated in VO₂ max test to calculate their 75% VO₂ max workload with BCAA injection and without BCAA injection. All exercise test were continued until subjects stopped because of fatigue. There were no big changes in the total exercise performance between BCAA injection experimental conditions. In the blood isoleucine, leucine, arginine, and phenylalanine concentration, there were no significant differences between BCAA injection experimental conditions(p>.05). The blood glutamate concentration was decreased following exercise, and end of exercise were a little bit increased. The blood alanine concentration was increased and there were significant differences at the end of exercise between BCAA injection experimental conditions(p<.05). The blood ammonia concentration was increased during exercise, but there were no significant differences between BCAA injection experimental conditions(p>.05). In this study, there was no positive effect of BCAA injection as a ergogenic aids and pre-exercise BCAA injection might be lead to premature fatigue.

The purpose of this study was to the Change of Exercise physical strength and Blood lactate concentration in Middle Women at Maximal Exercise test. None of them has any illness and use of any medication during the experiment. The subjects of study were 14. The experiments group were moderately trained running 3 days or more/week (G1=7) and comparisons groups 3 days under/week (G2=7). All subjects participated in Maximal Exercise test workload. All exercise test were continued until subjects stopped because of fatigue. The present study showed there VO₂max, VEmax, EX-Time in experiments group was higher than comparisons groups and there was significant difference between comparisons groups(p<.05). But there was no significant difference HRrest, HRmax, VO₂rest, VErest between comparisons groups(p>.05). The blood lactate concentration was increased during exercise, but there were no significant differences between comparisons groups(p>.05). Consequently the exercise physical strength in raised regular physical activity and frequently exercise training in the 3 days under/week. These data suggest that study about blood analysis for increasing levels of may prevent or lower coronary heart disease risk.

This study analyzed the comparative effect of Cooper exercise and continuous aerobic exercise for 10-12-year-old children with obesity for 60 minutes daily, three times a week for 12 weeks. The selected research participants were 76 children consisted of 54 boys and 22 girls with the %fat rate over 30% and were checked for the BMI, and %fat for the obesity index and blood lipid component for TC, TG, HDL-C, LDL-C and TC/HDL before and after the program, A 12-minute running was exercised for cardiorespiratory endurance, The intensity level of HRmax 55%-65% with the Karvonen formula measured the target heart rate for the exercise, The continuous aerobic exercise was performed for 40 minutes during the main exercise, and Cooper exercise was carried out by having the research participants carry a sand bag weighing 5% of theft body weight, A two-minute dynamic break was allowed after every 12-minute exercise. The repetitive measurement value for the pre- and post-programs was analyzed for the changing factors among the groups by using the comparative t-test analysis. A significant decrease occurred between the two groups as the result of the exercise program, weight, changes in the rate of the body formation for obesity; however, no statistical significance was resulted among different exercises, Further, the LBM was increased for every group but no statistical significance was supported, All the comparative groups showed a significant increase; however, the LBM was not significantly increased according to the statistics. The change in the blood lipid component significantly decreased for both groups; but it was significantly increased for the HDL-C, For the case of the comparative group, a significant increase was resulted; while a significant drop was evidenced for the HDL-C. For the change in the cardiorespiratory endurance, statistically significant increase was observed for the continuous exercise group and the Cooper exercise group while the comparative group showed no meaningful changes. As a result, an exercise program can significantly improve the changing factors for body shape and body formation of the children with obesity, and effectively play a role for the diseases related to arteriosclerosis and coronary heart disease. No significant difference between the two exercise groups entails a necessity for a long-term program when designing an exercise program for children with obesity, rather than a short-term program according to nutrient supply and exercise mode considering the fact that they are children in grow.

장성훈,최재욱 大韓産業醫學會 1991 대한직업환경의학회지 Vol.3 No.1

One of the important occupational disease is the earbon disulfide poisoning in Korea. But there had been controversies about the diagnosis of CS₂poisoning in relation to Workers Compensation. We reviewd the CS₂poisoning cases occurred in one viscose rayon factory and the diagnostic methods of CS₂poisoning in Korea. The major clinical apperance of the CS₂poisoning in Korean is CNS damage (34.3%-87.5%), PNS damage (34.2-100.0%), ophthlamoogicae abnormality (31.6-87.5%), and renal damage (23.7-50.0%). This aspect is similiar to those of Japan rather than those of Western European. Diagnostic method of CS₂poisoning in legal periodic examination has to be amended. The future study will be evaluation of health effect and early diagnostic techniques about low concentration CS₂exposure.
