Many studies revealed the neuroprotective, cardioprotective, and chemopreventive actions of dietary flavonoids. The plausible mechanistic interpretation of the various effects of flavonoids was concentrated on the anti-oxidant or free radical-scavenging properties of these phytochernicals, both in model systems and under in vivo conditions. While there has been a major focus on the anti-oxidant properties. there is an emerging view that flavonoids and their in vivo metabolites. do not act as conventional hydrogen-donating anti-oxidants. but they may exert regulatory functions in cells through actions at protein kinase or lipid kinase signaling pathways. Flavonoids and more recently their metabolites. have been reported to act at phosphoinositide 3-kinase(PI 3-kinase). Akt/protein kinase B(Akt/PKB), protein kinase C (PKC), mitogen activated protein kinase(MAP kinase), and various tyrosine kinases signaling cascades. Inhibitory or stimulatory actions at these pathways are likely to affect cellular function profoundly by altering the phosphorylation state of target molecules and by modulating gene expression. A clear understanding of the mechanisms of action of flavonoids, either as anti-oxidants or modulators of cellular signaling pathways, and the influence of their metabolism on these properties are key to the evaluation of these potent biomolecules as anti-cancer agents, cardio-protectants, and inhibitors of neurodegeneration.

Mature articular cartilage is an aneural, avascular, and alymphatic specialized form of tissue 1, 2. 6, 9, 12, 14, 15, 16, 20, 25, :0). The initial degeneration of articular cartilage may occur spontaneously with normal wear and tear in aging cartilage, or it may occur in articular cartilage that has been damaged by the local conditions, such as injury or synovectomy. It is the purpose of this report to study the ultrastructural and light microscopical appearance of the articular cartilage after synovectomy and cutting the cruciate ligaments of rabbits. Thirty young rabbits each weighing about 2.0kg were used for the experimental study and the animals were sacrificed at time intervals of 3, 7,14.28, and 42 days respectively after the synovectomy or cutting the cruciate ligaments. The tissue were decalcified and prepared by standard paraffin embedding procedure and stained with hematoxylin and eosin for histologic observation. For electron microscopy, the specimen fixed in 4% glutaraldehyde for 4 hours and postfixed for 2 hours at 4°C with 1% osmium tetraoxide in 0. 1 M phosphate buffer with pH 7.426). All tissues were dehydrated in graded alcohol and embedded in Epon 812 according to standard procedures. They were cut into section of 500 ? with a glass knife. The sections were mounted on copper grids, stained with uranyl acetate and lead hydroxide and observed with the Hitachi 11-E Electron Microscope. The results of the light and electron microscopic findings are as follows; 1. The degeneratve changes of the articular cartilage were appeared after 7 days and became increasingly severe in later samples in the groups of synovectomy. But the degenerative changes of the articular cartilage obtained 6 weeks after synovectomy in light microscope were not severe. 2. The degenerative changes of the articular cartilage were appeared after 7 days and became increasingly severe in later samples in the group of the cutting the cruciate ligaments. 3. By the electron microscopic findings, the degenerative changes of the articular cartilage were appeared after 1 week and continued steadily up to 6 weeks in the group of synovectomy. And the degenerative changes of the articular cartilage in the group of the cutting the cruciate ligaments were severe in degree comparing to the group of synovectomy.

MRI 아티팩트의 제거에 관한 연구

In this study, we present, an algorithm for canceling MRI artifacts due to some translational motion in patient’s head part. Assuming that the head part moves up and down due to patient's breathing which often makes problems during MRI imaging, rigid translational motions are treated here. Unlike the conventional iterative phase retrieval algorithm in which there is no guarantee for the convergence, this method is based on the MRI imaging process and the analysis of image property. A new constraint condition with which the image component and the motion component in the MRI signal can be separated by a simple algebraic operation is extracted After the x(read out) directional Fourier transformation of MRI signal is taken the y(phase encoding) directional spectrum phasing value is just an algebraic sum of the image component and the motion component. Meanwhile, at it is known that the density of subcutaneous fat area is almost uniform in the head tomographs, the density distribution along an y directional line on this fat area is regarded as symmetric shape. If the density function is symmetric, the phase of spectrum changes linearly with the position. Hence, the departure component methods, the motions in the x direction and the y direction are treated simultaneously. However, the x and the y directional motion is canceled by each different algorithm in two steps because the features of x and y directional motions are different from each other in this method. The x directional motion is estimated by detecting the edge boundary between the non-zero area and the zero area of the spectrum and is canceled by shifting the spectrum in inverse direction. The y directional motion is canceled by using the constraint condition which separates the true image component and the motion component. Finally, the effectiveness of this algorithm is shown by using a phantom image with simulated motion.

The purpose of this study is to know what is the efficient exercise and to determine the most efficient exercise in lumbar flexibility. Therefore, in this experiment, three hip joint flexion exercises were carried out in order to see which improves the most in lumbar flexibility. The test was carried out with E university students divided in three groups, Group A: hip flexion and knee extension with supine, Group B: hip flexion and knee flexion with supine and Group C: hip flexion and knee extension with sitting- each group consisted of 13 people and everyone participated in doing the warming-up exercise, main exercise and cool-down exercise which lasted about 20 minutes and this program was done 5 times a week during the period of 6 weeks. To find out the results, we did the sit and reach test using T.K.K.4308B of Japan. We measured the results once a week and in total 8 times including initial and last measurement. The result of this study showed that each exercise method applied in each group contributed in improving lumbar flexibility. The following results show the improvement in lumbar flexibility. According to this study, Group C(T=-14.305, P=.000) had the highest degree of flexibility improvement followed by Group A(T=-10.343, P=.000) and then Group B(T=-12.012,P=.000). This study showed that the hip joint flexion exercise of these three groups have a positive effect on lumbar flexibility improvement. Furthermore, it has been proved from the study that the best among the three methods in increasing the lumbar flexibility is the exercise done by Group C.The purpose of this study is to verify the difference of effect between group and period in order to find out effect on lumbar flexibility of treatment modality(stretching, heat - stretching) and period. The subject was chosen from the mild physically normal person who range from 20 to 40 years old without any neurological problem. 본 연구는 대학생들을 대상으로 유연성 향상을 위한 여러 가지 방법 중 임상에서 주로 사용되어지는 고관절 굴곡 운동 방법을 3가지로 나누어 6주간 실시한 후 앉아 윗몸 앞으로 굽히기(Sit-and-Reach Test)로 측정 비교하여 어느 운동이 허리 유연성에 더 많은 영향을 주는지를 알아보고, 그 효과의 차이를 살펴보는데 목적이 있다. 총 39명의 대학생을 대상으로 13명씩 세 그룹으로 나누어 6주간 실험을 실시하였으며 측정방법으로는 좌 전굴 측정계를 사용하여 운동전과 운동 후의 허리 유연성 변화를 분석한 결과 다음과 같은 결론을 얻었다. 1. 각 그룹에 적용된 각각의 운동 방법 모두 피 실험자들의 유연성 향상에 기여를 한다. 2. 세 그룹의 유연성 향상의 정도가 차이가 있고 유연성 향상 정도는 C그룹, A그룹, B그룹 순으로 향상 되었다. 이상의 결론을 종합해 보면 세 그룹의 고관절 굴곡운동은 허리유연성 향상에 긍정적인 영향을 미쳤으며 그 중 그룹 C의 Hip flexion and knee extension with sitting방법이 허리 유연성을 증가시키는데 가장 큰 효과를 보였다.
