Fibrinolytic activity of fermented kimchi and ingredients used for the preparation were assayed by measuring the lysis area on plasminogen-rich fibrin plate. Fermented kimchi and pickled fish sauces from changlan, prwan, and anchovy showed the activity, and the activity of pickled fish sauces were high in the order of pickled changlan, pickled anchovy(pickled mulchi), and pickled prawn. However, the activity of kimchi may not be attributed to pickled fish sauce because kimchi containing fish sauce did not possess activities before fermentation. To investigate fibrinolytic agents in the kimchi if protein, the activities were determined from the samples heated for 30min at 100℃. There was no changes in the activities before and after heat treatment indicating the agents may be components other than protein. Since major changes occur during kimchi fermentation were increased sour taste due to production of organic acids such as lactic, citric, oxalic, and succinic acids, the authentic organic acids present were examined for fibrinolytic activities. The results indicates that the major component posses the activity is lactic acid.
In order to study the methods of measuring the Body Fat among the middle age females who have been actively involved in sports for about one year(subjects;16), a comparative analysis was performed between Skinfold thickness method and BIA(Bioelectrical Impedence Analysis). The results are as follows: 1. It was shown that there is no difference between Skinfold thickness measurement and BIA measurement in measuring the % Fat(P>.05). 2. In terms of quantity of Fat, there was no difference between Skinfold thickness measurement and BIA measurement(P>.05). 3. In measuring LBM, the two methods showed no difference between them(P>.05). 4. In measuring TBW, the two methods also showed no difference between them(P>.05).
당뇨병에서의 혈전생성 기전에 관련된 주된 요인을 관찰코져 흰쥐를 4주간 사육한 후 streptozotocin(STZ)으로 당뇨를 유발한 후 6일째에 희생하여 당뇨쥐에 있어서의 phospholipase A₂ 활성변화에 따른 조직의 과산화적 손상과 혈소판 응집능 등의 변화를 관찰한 결과는 다음과 같다. 체중증가는 STZ를 투여한 후에는 STZ 투여군에서 현저하게 감소하였다. 식이섭취에 있어 STZ injection 후, DM군은 16% 증가하였다. 식이효율은 STZ injection 후 DM군은 정상군에 비해 유의적으로 감소하였다. 혈청 중의 총 지질과산화물가는 정상군에 비해 DM군은 2.5배 높았다. HDL 중의 TBARS는 정상군에 비해 DM군은 약 1.6배 정도 높았고 LDL 중의 TBARS는 정상군에 비해 DM군에서 4.8배의 높은 증가를 보였다. 혈소판 phospholipase A₂ 활성은 DM군은 정상군에 비해 42% 증가하였다. 혈소판 cyclooxygenase 활성은 정상군에 비해 DM군이 2배 정도 높은 수준이었다. 혈소판 중의 TXA₂ 농도는 정상군과 비교하여 DM군에서 169%로 현저하게 높았고 대동백 PGI₂의 농도는 정상군에 비해 DM군은 낮은 수준을 보였으며 대동맥 PGI₂와 혈소판 TXA₂의 비는 DM군에서 정상군에 비해 55% 낮았다. 결론적으로 STZ 유발 당뇨쥐에 있어서는 혈청 지질과산화물 수준의 증가와 더불어 phospholipase A₂ 활성이 증가되었으며 따라서 cyclooxygenase가 유도하는 AA cascade 활성화에 의해 TXA₂ 생성증가 및 PGI₂/TXA₂ ratio의 감소가 관찰되었다. 이러한 결과는 당뇨병 질환에서 나타나는 동맥경화증, 심혈관계 질환 등의 여러 혈관계의 병리적 현상들이 당뇨 상태에서의 지질대사 이상으로 인한 지질과산화물의 증가와 그의 독성으로 인한 여러 혈소판 관련 인자들의 활성화와 밀접하게 연관되어 나타나는 것을 시사하는 것이라 하겠다. The relation between lipid peroxidation and thrombotic reaction were investigated in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats weighing 100±10gm were randomly assigned to normal and STZ-induced diabetic group(DM). Diabetes was experimentally induced by intravenous injection of 55mg/kg of body weight of STZ in citrate buffer(pH 4.3) after 4 weeks feeding of basal diet. Animals were sacrificed at the 6th day of diabetic states. Body weight gains were lower in diabetic group after STZ injection. Serum levels of thiobarbituric acid reacting substances(TBARS) that were markedly increased in DM group compared with of normal group. TBARS levles of HDL and LDL were similar patterns to total TBARS of serum. Activities of platelet phospholipase A₂(PLA₂) were higher in diabetic group than those of normal group. Activities of platelet cyclooxygenase were 106% in DM group than normal group. Platelet thromboxane A₂(TXA₂) formation was increased in DM group than normal group. Production of aortic prostacyclin(PGI₂) was lower in diabetic group than that of normal group. PGI₂/TXA₂ ratios were decreased by 55% in DM groups than those of normal group. The present results indicate that STZ-induced diabetic rats are more sensitive to oxidative stess which leads to acceleration of lipid peroxidation and platelet aggregability. In conclusion, accelerating effect of lipid peroxidation and thrombogenesis in diabetic state is regarded to be resulted from enhancement of PLA₂ activity and arachidonic acid metabolism, inhibition of antiaggregating agent and aortic PGI₂ formation.

This study investigated the relationship among the flight stress, disease and eating behavior of the Airline cabin crews. Self administered questionnaires were collected from three hundred and twenty cabin crews. Statistical data analysis was completed using a SPSS v.10.0 program. The results were summarized as follows: Before the flight, the maladaptation to the oversea foods was the most common stress for the crews less than one year flight experience. During the flight, fastidious arrangement and loss of appetite due to overwork were the most common stresses. After the flight, anorexia due to jet lag was the most common stress. Backache and stomachache were the most common job-related ailments of the airline cabin crews. During the flight, the intakes of carbonated drinks and coffee were most common. After the flight, water was the most common drink they consumed.
The purpose of this study was to examine the effects of treadmill exercise on adolescents serum lipids. This study was a simple pre- and post-test design. The participants of this study were 7 middle-school students located in a metropolitan city, Korea. All participants were boys (mean age=15.81 years; SD=.36), and were treated as a experimental group. A 12-week treadmill exercise program (60 min. & 3 times per week) was implemented. To collect blood samples and analyze TG, TC, HDL-C, and LDL-C, the Becton Dickison Vacutainer System was used. Results revealed that the participants' TG, TC, LDL-C were significantly decreased after the program. However, no significant differences were found in HDL-C even though there was an increase after the program. It was concluded that a 12-week treadmill exercise program can be as effective as other types of aerobic exercise in improving adolescents' serum lipids. Recommendations for future research and practice were provided.
This study is to present more effective starting skills through analysis of kinematic characteristics of starting motions in 300m Time Trials of Inline Skating. To achieve the goal, 6 athletes, 3 in the national team and 3 in business teams were chosen and their starting motions were examined with three-dimensional image analyses. The results of analyses in regard of speed of the body center and linear velocity of articulations of lower limbs by sections of starting motions are as follows: 1) Acceleration in the starting section is determined by the speed and the position of bodily center at the moment of leaving the ground not by the aerial movements. In case of the central position, though it is effective to reduce the air resistance by lowering the upper part of the body maximumly, it is reasonable to accelerate by raising the upper part of the body to some degree for the running posture at the lower speed in the starting section. At the lower speed in the starting section, since the push-off motions are made with the front part of skates at a point, not while gliding, the angle in the articulations of lower limbs is bigger. This shows that the faster changes from the running posture to the gliding skills is made, the more effective motions can be made. 2) At the moment of starting, acceleration by reducing the angles of knees to increase safety on the ground is reasonable, but wheels should touch more with the ground to minimize the impact and friction of skates. In the starting section, it is efficient to minimize the period of time in touching the ground. For this, it is necessary to train for taking motions without slippage while touching the ground. 3) While 3 athletes in business teams kicked the ground as running right after the starting, the others in the national team slid on the ground. As the number of steps increased, the movable speed changed quickly. Thus the movable speed of athletes in the national team indicated big differences in two to three steps. If these factors are well supported, the push-away starting method might be better than the running starting method in terms of improvement of records.
This study has executed the precedent and example research to emphasize our recognition on the importance of dance production. In the precedent research, it has analyzed effects, on the basis of composition, picturization, movement(Korea Culture Arts Promotion, 1987), rhythm(Woi-sun, Pak) of the performance from a piece of work, Giselle, as well as the application for producing methods. It is considered that the productions much easily understood by the audience are even more important than the dancing itself by a dancer. However, it has become less professional since the dancer should perform dancing and producing at the same time, taking into consideration of a domestic circumstance and study hasn't been made esp. in drama dances or creation dances as much as it is required. In the long run, it will become a turning point rapidly to improve the domestic dancing world if it begins to train not only professional dancers for production but dancers and choreographers.
