The aim of this study is to learn the effects of ST36 ST44 and ST25 ST36 electroacupuncture stimulation on high fat diet-induced obese mouse. The control group was provided with high fat diet without electroacupuncture stimulation, while the experimental group received a electroacupuncture stimulation on ST36 ST44 and ST25 ST36 with three frequencies (10Hz, 100Hz, 200Hz) for 5 times a week during five week periods with the high fat diet. We investigated the body weight, weight gain, and food intake. After the electroacupuncture stimulation, a significant inhibition of increase in weight was found in the experimental group compared with the high fat diet group. But there were no significant differences made by the change of acupoint combinations and frequencies. After the electroacupuncture stimulation, no significant change was found in the food intakes, but the weight gain a week was decreased compared with the high fat diet group. Electroacupuncture stimulation may be effective in treatments of obesity to high fat diet, But no significant difference was found between three frequencies.
BACKGROUND/OBJECTIVES: Soy isoflavones are structurally similar to estrogen and bind to estrogen receptors, suggesting that they exhibit estrogenic activities; therefore, they are referred to as phytoestrogens. Fermentation may affect the bioavailability of isoflavones altering soy isoflavone glycosides in the form of aglycones. Thus, this study investigated the effects of fermented soybeans by Rhizopus oligosporus on bone metabolism in both young rats as a pilot test and in ovariectomized (ovx) old rats as a model of menopause. MATERIALS/METHODS: In the pilot test, a total of 24 seven-week-old female Sprague-Dawley (SD) rats were fed one of three diets for a period of four weeks: casein, unfermented soybean product, or fermented soybean product by R. oligosporus. In the ovx rat model, 20-week-old SD rats weighing 260-290 g underwent either sham-operation (n = 10) or bilateral ovariectomy (n = 30) and were then fed the AIN-93M diet for one week. Thereafter, rats were fed sham-casein, ovx-casein, ovx-soybean, or ovx-fermented soybean diet for five weeks. After decapitation, femoral bones were isolated and preserved in 9% formalin for assessment of bone mineral density (BMD), bone mineral content (BMC), and bone-breaking strength (BBS). RESULTS: Ovx rats showed significantly increased weight gain and decreased uterine wet weight. Of particular interest, ovx rats fed fermented soybeans showed increased uterine wet weights compared to control rats. Fermented soybean diet caused a significant increase in plasma 17-${\beta}$ estradiol concentrations in young rats, and 17-${\beta}$ estradiol levels were enhanced in ovx rats to match those of sham-operated ones. Significantly lower femoral BMD and BMC were observed in ovx rats compared to sham-operated controls, whereas bone areas did not differ statistically among the groups. In addition, BBS tended to be increased in ovx rats fed soybeans and fermented soybeans. CONCLUSIONS: Supplementation of fermented soybeans could have preventive and therapeutic effects against osteoporosis in postmenopausal women.

The rapid growth of the Korean fashion industry has contributed greatly to the establishment of various fashion associations that have appeared since the 1960s. Seoul Fashion Week celebrated its 20th anniversary; there is now a crucial opportunity for the role of Korean fashion associations to the world's top five fashion collections. This study examines and compares the various roles of Korean fashion associations and the fashion associations of France, Italy, USA, and UK. Based on the comparison results, suggestions for the roles of Korean fashion associations are as follows. The following three roles are important in both Korean and foreign associations: stable operation of collections, the creation of various funds to support fashion designers, and foster new designers through linkage with the education programs for textiles and design. Mutual cooperation among various associations is essential to achieve future goals. The specific activities of foreign associations are highly suggestive for direction. In addition to the pursuit of members' rights, it is also desirable to conduct various social activities. It is necessary to create various events that ordinary citizens and students can enjoy in addition to achieving the goal of promoting and selling products at the Seoul Fashion Week. In order to overcome various difficult situations facing Korea and to prepare for a great leap forward for the fashion industry, Korean fashion associations should spare no effort to overcome mutually conflicting interests and understand other perspectives from a macro perspective.
The aim of this research is to grasp the relation between lumbago incidence rate and research hypothesis in the effects of sex life of the middle-aged couples in Taejon area upon lumbago. And so, this writer had questionaired the 400 middle-aged couples in five gus, Taejon megalopolis -Jung-gu, Seo-gu, Dong-gu, Yuseong-gu, and Taedeok-gu - from April 21, 1998 to May 10, 1998. Of them, total 209 question papers were drawn back; male 102, female 107. Analysis of the data is as follows. 1. 145(69.37%) subjects of total 209 had experience in lumbago after their sexual lives. 2. In the number of sex life a week, one or two times of lumbago incidence rate were the most rate as 41.55% and each other had a statistically significant relation (P 0.01). 3. In age and lumbago incidence rate, their thirties was 37.75% and each other had a significant relation (P 0.05). 4. In weight and lumbago incidence rate, the level of $50kg{\sim}60kg$ was highest and each other didn't have a significant relation (P 0.05). 5. In the mean time of sexual life, the period of $11{\sim}20$ minutes was 29.47% and each other had a significant relation (P 0.01). 6. In week time zone of sexual life and lumbago incidence rate, midnight was the highest rate, 36.23% and each other didn't have a significant relation (P 0.05). 7. In the lumbago incidence rate according to bedroom structure of sexual life, a bed was 38.17% and each other had a significant relation (P 0.05). 8. In the lumbago incidence rate according to sexual posture, a normal position showed the highest rate, 46.12% and each other didn't have a significant relation (P 0.05). Putting the abovesaid results together, lumbago has relation to the number of sex life a week, age, the mean time of sexual life, and bedroom structure of sexual life. Therefore, it is thought that it is necessary that middle-aged couples periodically study the educational programs to make an education for lumbago prevention, etc. the key points.
This study was conducted to determine factors affecting detection threshold and the optimally-preferred concentration for sweet taste, since investigation into factors decreasing sensitivity or increasing preference for sweet taste is important to prevent overconsumption of simple sugar. Subjects were 70 first-grade middle school students in the Gyeonggi-Do. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly were determined by sensory evaluation. A self-administered questionnaire was used to obtain the information regarding health-related lifestyle practices, dietary habits, preference for and eating frequency of Westernized foods and frequencies of eating foods other than home-made. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly of the subjects were 0.204% and 14.44%, respectively. Subjects who exercise less (< 30 minutes/week except PE class), skipping meals (${\geq}$ 3/week), type of breakfast rather than traditional Korean meal and frequent eating out and buying foods from school tuck-shop tended to have higher sweet taste threshold. There was significant positive correlation between the sucrose threshold concentration and fried chicken preference or eating frequency of hamburger. Those who exercise less (< 30 minutes/week except PE class) did have significantly higher optimally-preferred sweetness of omija jelly, which tended to be higher in the subjects who had more (${\geq}$ 4 out of 10) behavioral or psychological stress symptoms and who had early getting-up time (before 7 am). There was significant positive correlations between the optimally-preferred sweetness of omija jelly and pizza preference, instant noodle eating frequency or sum of eating frequencies of five fast foods. From the results of this study, it was suggested that middle school students should make efforts to stop skipping meals, exercise more, eat Korean traditional breakfast and reduce the frequencies of eating out and using instant/fast foods in order to prevent overconsumption simple sugar.
The negative impacts of roads on wildlife mortality have been well documented, and one of the most significant impact is wildlife-vehicle collisions (WVCs) in most countries throughout the world. While road impacts on wildlife are a truly global concern with a large socio-economic cost, few researches in Korea have been quantified road-kill occurrence on highways or identified extensively seasonal and geographic patterns of this phenomenon. Therefore, we analyzed highway mortality of wild mammals in Korea using database from five years of nation-wide data on WVCs, and estimated road-kill density by standardizing on per km and per $10^3$ vehicle basis. During 2008 through 2012, a total of 10,940 wildlifes were reported killed on highways, with an average of 2,188 cases per year. There were 2,376 road-kills in 2012, and this equates to 0.01 road-kills per km per week or one road-kill every 88.5 km per week. For time of day, road-kills occurred more frequently in the early morning (05:00-08:00, 38.3%), and day of week did not have a significant influence in any individual year. The road-kill was highest in the spring (March- May, 33.0%) and least in the winter (December-February, 16.1%), and the most frequently killed native species were of Korean water deer (79.7%), raccoon dog (12.7%), Korean hare (3.1%), and leopard cat (1.2%). The overall standardized kill-rate (number/10 km/1,000 vehicles/month) in 2012 was 0.057 with highest on Dangjinyeongdeok highway (0.476), followed by Yeongdong (0.274), Sooncheonwanju (0.233), Iksanpohang (0.187), and Joongang (0.150). This study highlights that the frequency of WVCs are prevalent throughout the highways in Korea. Further work is needed to determine whether such a level of mortality is sustainable from an ecological point of view.
Objectives : This study was designed to examine the effects of hyperbaric oxygen therapy on cerebral infarction. Methods : Fifty-five patients with acute or subacute cerebral infarction were classified into two groups, the study group and control group. The study group was treated by hyperbaric oxygen therapy(HBOT) for 2 weeks(5 times/week) and the control group wasn't treated by HBOT. We compared the score of National Institutes of Health Scale(NIHSS scale) between two groups. We subdivided the study group by TOAST classification and onset stage, and compared the results. All of this data was analyzed by statistical method. Results : The study group patients who were treated by hyperbaric oxygen therapy saw more improvement than the control group patients in NIHSS score, and there was significant consideration. Among the study group patients, we saw more improvement during the first week period than in the course of the second week, and there was significant consideration. Conclusion : These results suggest that hyperbaric oxygen therapy(HBOT) could be a useful medical treatment to treat cerebral infarction. Further studies are needed on more cases to make sure that hyperbaric oxygen therapy (HBOT) is surely effective for cerebral infarction.
Cleaving host immunoglobulins is a well known mechanism of evading host immune reactions exploited by helminth parasites, Secreted cysteine proteases of helminth are a part of enzymes cleaving host IgG. Porogonimw westemani produces at least six different species of the cysteine protease in its developmental stages. This study was undertaken to evaluate comparatively the activities against human IgG by the different enzymes. When the metacercariae, which secrete 27 and 28 kDa cysteine proteases, were incubated in human IgG solution, IgG was degraded at its hinge region. Further incubation resulted complete hydrolysis. From 4-week and 7-week old juveniles and 16-week old adults of p. westemani, five different enzymes at 15, 17. 27 28 and 53 kDa have been purified, if the enzyme with the same molecular mass is regarded to be identical. In cleaving human IgG, each cysteine protease exhibited decreasing activities with age.
Compensatory growth of juvenile olive flounder Paralichthys olivaceus fed different diets with different feeding regime was compared. Four hundred fifty fish (twenty five fish per tank) were randomly distributed into 18 of 180 L flow-through tanks. Six treatments were prepared: fish were hand-fed with the control (C) diet to satiation twice a day, six days a week, for 8 weeks (C-8W treatment); and other groups of fish were starved for 2 weeks and then fed with the C, high protein (HP), high carbohydrate (HC), high lipid (HL), and combined protein, carbohydrate and lipid (CPCL) diets to satiation twice a day, six days a week, for 6 weeks, referred to as C-6W, HP-6W, HC-6W, HL-6W, and CPCL-6W treatments, respectively. Final body weight of fish in HP-6W treatment was higher than that of fish in C-6W, but not different from that of fish in C-8W, HC-6W, HL-6W and CPCL-6W treatments. Specific growth rate of fish in HP-6W treatment was higher than that of fish in all other treatments except for fish in CPCL-6W treatment. Feeding rate of fish in C-8W treatment was higher than that of fish in HP-6W, HC-6W, HL-6W and CPCL-6W treatments, but not different from that of fish in C-6W treatment. In addition, feeding rate of fish in C-6W treatment was higher than that of fish in HP-6W, HL-6W and CPCL-6W treatments. Feed and protein efficiency ratios of fish in HP-6W, HC-6W, HL-6W and CPCL-6W treatments were higher than those of fish in C-6W treatment. None of moisture, crude protein and ash content of the whole body of fish excluding the liver was different among treatments. Dietary supplementation of protein, carbohydrate, lipid and their combination could improve compensatory growth of fish when fish were fed for 6 weeks after 2-week feed deprivation; especially, supplementation of dietary protein was the most effective to improve compensatory growth of fish.
Purpose: This study was designed to evaluate whether magnetic resonance imaging (MRI) is appropriate for detecting early changes in the mandibular bone marrow and pulp tissue of rats after high-dose irradiation. Materials and Methods: The right mandibles of Sprague-Dawley rats were irradiated with 10 Gy (Group 1, n=5) and 20 Gy (Group 2, n=5). Five non-irradiated animals were used as controls. The MR images of rat mandibles were obtained before irradiation and once a week until week 4 after irradiation. From the MR images, the signal intensity (SI) of the mandibular bone marrow and pulp tissue of the incisor was interpreted. The MR images were compared with the histopathologic findings. Results: The SI of the mandibular bone marrow had decreased on T2-weighted MR images. There was little difference between Groups 1 and 2. The SI of the irradiated groups appeared to be lower than that of the control group. The histopathologic findings showed that the trabecular bone in the irradiated group had increased. The SI of the irradiated pulp tissue had decreased on T2-weighted MR images. However, the SI of the MR images in Group 2 was high in the atrophic pulp of the incisor apex at week 2 after irradiation. Conclusion: These patterns seen on MRI in rat bone marrow and pulp tissue were consistent with histopathologic findings. They may be useful to assess radiogenic sclerotic changes in rat mandibular bone marrow.
