Objectives : This study was designed to protect effect on atherosclerosis through regulation of low density lipoprotein(LDL) by 70 % ethanol extract Ganoderma lucidum (GL) in LDL receptor knockout mouse (LDLr ko mice) fed Western diet.Methods : The LDLr ko mice were divided into 3 groups ; Control, GL100, and GL300. After grouping, LDLr ko mice were fed Western diet. The GL (100 or 300 mg/kg body weight/day, p.o.) was administered every day for 8 weeks. The body weight and food intake were measured every day. The changes in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, triglyceride (TG), total cholesterol (TC), and high-density lipoprotein (HDL) in serum were analyzed after experiment.Results : The LDLr ko mice fed Western diet were increased body weight gain and blood biochemistry parameters such as ALT, AST, TG, TC, and LDL. However GL300 group significantly reduced the body weight. Also TG, TC, and LDL level did not increase. The levels of ALT, AST, HDL were not changed. Also, LDLr ko mice model liver were observed lipid drop, but GL groups did not appear. Futhermore, histological analysis of GL groups aorta tissue were similar to NOR groups.Conclusions : We confirmed that whether GL administration is protect atherosclerosis or not. As the results, blood biochemistry and histological analysis did not changed much in GL administration groups. This study provides scientific evidence that GL protect the atherosclerosis through the reduction of LDL cholesterol. Therefore GL has potential medicine inhibition of atherosclerosis.

Purpose: Blow out fracture resulting from facial trauma is of high frequency among facial bone fractures, and can cause severe complications. So, proper management and close observation after operation are needed. So far, Computed tomography has been the best choice in the evalution following orbit wall reconstruction. However, cost - effectiveness, accessibility to patients and hazard of radiation exposure of computed tomography require supplementary measure for the evaluation following orbit wall reconstruction. This study was performed to describe the effectiveness of ultrasonography in the evalution following orbit wall reconstruction. Methods: A retrospective study was performed on 40 patients who underwent orbit wall reconstruction from June, 2008 to July, 2008. The patients' ages ranged from 13 to 65 years (mean 27.5 years), and this group was compsoed of 27 male and 13 female patients. The follow up period ranged from 2 weeks to 28 weeks (mean 11weeks). Preoperatively, all fractures were diagnosed using computed tomography. Ultrasonography for all cases, and computed tomography for 2 cases were performed for evaluation following orbit wall reconstruction. Results: Reduction of herniated orbital soft tissue and orbit implant was identified by using ultrasonography in 38 cases out of 40 cases. In other cases which we could not identify the orbit implant, computed tomography was performed. Con clusion: Compared to computed tomography, ultrasonography is simple, inexpensive and convenient method. Ultrasonography can be used as supplementary measure to computed tomography in the evaluation following orbit wall reconstruction for elective patients.

The purpose of present study was to examine how each clothes colors on the basis of 5YR 7/3 face color affect clothes colors images as follows : (1) what general consciousness of clothes colors in, (2) how the impression of the harmony of 5YR 7/3 face color and clothes colors is, (3) when we divide clothes colors according to the property of colors- chromatic color and achromatic color, cool color.neutral color.warm color, in tone, in color colume- if there is the difference of visual evaluation, (4) image analysis of 45 clothes colors with the view of each kind of adjectives. The result of this study is as the following: 1. As a result of the analysis of general consciousness on clothes colors, when subjects chose clothes, they most considered colors and they also considered their face colors. They would choose the color of clothes, which were becoming to their having clothes colors or their face colors when they bought clothes. 2. The impressions of coordination of 5YR 7/3 face color and clothes colors consisted of three dimensions - evaluation, activity and harmony. 3. It was known that as a result of the analysis of visual evalutional differences according to dividing the clothes colors by property of colors, there were such notable differences that they might effect the coordination images of face color and clothes colors differently. 4. After arranging 45 clothes colors on the graphs in 17 adjectives, gethering them thogether in each dimension and as the result of the analysis in the evaluation dimension, estimation of yellow, light green column were low and that of achromatic colors were high. That is, it was known that the evalution dimension was concerned with hue of the color properties. In activity dimension, there were different image according to each adjectives. That is, it was known that the evalution dimension was concerned with hue of the color properties. In activity dimension, there were different image according to each adjectives. That is, it was known that the activity demension was concerned with value and chroma of the color properties. In harmony dimension, achromatic columm was high and yellow, green yellow, vivid green columm were low in harmony. That is, it was known that the harmony demension was concerned with hue of the color properties.
