This study was peformed to elucidate the effects of antler, red ginseng, safflower seed, ipriflavone and estrogen on ovariectomized rats. The rats were fed with Ca and P deficient diet for five weeks to induce osteoporosis. After this period, these animals were fed with normal for and treated every other day with antler(600mg/kg, PO), red ginseng(200mg/kg, PO), safflower(200mg/kg, PO), ipriflavone(80mg/kg, PO) and estrogene(400$\mu\textrm{g}$/kg, IM) for S weeks. During the treatment, the rats were examined for body, organ, femur and femur ash weights. And electron-microscopical examinations were also performed on femora. The results are summarized as follows : 1. The body weights of the antler, red ginseng, safflower, ipriflavone and estrogen-treated groups after five weeks of treatment, were 303.0$\pm$3.0g, 273.3$\pm$4.4g, 288.3$\pm$5.1g, 300.5$\pm$5.2g, 320.5$\pm$4.2g, respectively. They, except the red ginseng-treated group, were significantly higher than 278.4$\pm$2.7g of normal control group(P<0.05). And the body weight of non-treatment group was 29it.2$\pm$5.5g which was higher than that of control group, too. 2. The weights of left femur after five weeks of treatment were showed 0.83$\pm$0.2g by antler, 0.89$\pm$0.2g by red ginseng, 0.87$\pm$0.2g by safflower 0.83$\pm$0.1g by ipriflavone and 0.78$\pm$0.1g by estrogen-treated group. They were a little lower than 0.97$\pm$0.1g of normal control group. Non-treatment group showed 0.83$\pm$0.1g which was lower than that of control group but not significant. 3. The weights of ashed left femora after five weeks of treatment were showed 0.36$\pm$0.01g by antler, 0.40$\pm$0.01g by red ginseng, 0.41$\pm$0.01g by safflower, 0.36$\pm$0.01g by ipriflavone and 0.35$\pm$0.01g by estrogen-treated group. Those results were significantly lower than 0.43$\pm$0.01g of normal control group. And non-treatment group showed 0.29$\pm$0.01g of femoral ash which was significantly lower than that showed by control group(p<0.05). 4. The femoral Ca contents of the antler, red ginseng, safflower, ipriflavone and estrogen-treated rats were 19.6$\pm$0.7%, 17.8$\pm$1.1%, 18.8$\pm$0.9%, 18.0$\pm$1.1%, 15.3$\pm$1.1%, respectively, after five weeks of treatment. The femoral Ca contents of antler and safflower-treated groups were higher than that of control group which showed 18.2$\pm$0.9% of Ca The non-treatment group, showing 15.3$\pm$0.7%, had significantly lower content of Ca than normal group(p<0.05). 5. The weights of liver, spleen, and kidney in the osteoporosis-induced rats during the treatment with antler, red ginseng, safflower, jpriflavone and estrogen showed not significant changes. 6. The connections among the trabeculae of control group were maintained well, showing no bone loss. However, the connections among the trabeculae of non-treatment group were thinner than those of control group and were almost disconnected and the lacunae were found to be broadened. Antler and safflower-treated group showed only slight changes. The recovery rates were prominent in antler, safflower, estrogen-treated groups but they were insignificant in red ginseng and ipriflavone-treated groups.

This study investigates the progress of obesity in men from childhood to adulthood, by analyzing the measurement references from the 5th Size Korea. It also seeks to analyze the characteristics of obese figures through the comparison of body proportions to normal-weight people, to provide a basic reference for the development of new size categories and improved pattern grading. The age range is divided into three groups: children (2-7), teenagers (13-18), and adults (19-39). The results of research into the characteristics of body proportions of obese figures and the classification of different figure groups of obese people are as follows. The ratio between width and circumference for each part of the body was investigated according to body weight that was grouped into three different categories of low, normal, and obese body weights. The result demonstrated that in all the ranges of age, the obese groups had the lowest ratio between width and circumference in having a thick body shape. According to the results that compared the ratio of the circumference of each body part divided by the waist circumference, the obese group showed a low ratio that indicates that they have a bigger waist circumference than other parts of the body. Two factors are identified as contributing to obesity in analyzing the ratio of the circumference of body parts divided by waist circumference. Using the factor loadings of the upper and lower body obesity, a cluster analysis was carried out and three different categories of obesity were defined; lower body obesity, abdominal obesity, and upper body obesity. The obese groups of children and teenagers were mostly in body shape with lower obesity and abdominal obesity, whereas the adults group showed the obesity present in the upper body obesity that have fewer cases in lower body obesity.

Objectives: This study was performed to investigate the effects of overestimation of their own body shape on weight control behaviors, mental condition, physical activity, dietary behavior, health-related quality of life, and nutritional status among young Korean females. Methods: A total of 1,514 women aged 20-39 years who are not pregnant and lactating among those who participated in the Fifth Korea National Health and Nutrition Examination Survey (2010~2011), were analyzed and grouped into underestimation (n=120), normal estimation (NE, n=840), and overestimation (OE, n=554), based on their body perception compared to actual percent ideal body weights. Variables were compared between OE group and NE group. Results: The subjects in OE group were significantly younger (29.5 vs. 30.5 years, respectively p < 0.05) and had lower body mass index (20.9 vs. 22.2 respectively, p < 0.01), health-related quality of life measured by EQ-5D (EuroQol-5 Dimension)(0.97 vs. 0.98 respectively, p < 0.05), nutrition adequacy ratio (NAR) of protein (0.91 vs. 0.93 respectively, p < 0.05), phosphorous (0.93 vs. 0.96 respectively, p < 0.05), and iron (0.70 vs. 0.75 respectively, p < 0.01), and index of nutrition quality (INQ) of iron (0.84 vs. 0.89 respectively, p < 0.05) compared to those in the NE group. The results of logistic regression showed that unmarried status (OR 1.32; 1.01~1.72) and severely underweight/underweight status (OR 1.94; 1.01~3.75)/(OR 1.81; 1.34~2.45) were significantly related to the probability of overestimation by the subjects. Significantly more women in OE group practiced fasting, skipping meals, and taking prescribed pills to lose body weights and had skipped breakfast compared to those in the NE group. Conclusions: The results of this study suggested that the Korean young women's distorted perception of own body shape may be associated with undesirable weight control behavior, low quality of life, and lower nutritional status. Therefore, nutrition education for this group should include information on correct body shape perception and its importance.

The present study was conducted to estimate production performances, heritabilities, and genetic and phenotypic correlations on several economic traits in Korean native chicken. Data analyzed were the records of 1,096 pullets produced from 180 dams and 26 sires of Korean native chicken from April 19,1994 to February 26, 1995. Results obtained are surnmarized as follows: 1. The body weights(X${\pm}$SD) at 2, 8, 14 and 20 weeks of age were 114${\pm}$13, 690${\pm}$114, 1,163${\pm}$238, and 1,687${\pm}$349g, respectively. The age at first egg was 165.95${\pm}$14.54 days, and the number of eggs produced by 300 days of age were 70.78i23.47. The egg weights of the first egg and at 300 days of age were 37.88${\pm}$3.73 and 50.97${\pm}$3.69 g, respectively. 2. The heritability estimates of body weight based on the variance of sires, dams and combined components were 0.149, 0.298, and 0.224 at 8 weeks of age: 0.162, 0.220, and 0.192 at 20 weeks of age, respectively. 3. The heritability estimates of egg production traits based on the variance of sires, dams, and combined components were 0.232, 0.504, and 0.368 for age at first egg; 0.113, 0.172, and 0.143 for number of egg production by 300 days of age: 0.174, 0.352, and 0.236 for egg weight at 300 days of age, respectively. 4. The genetic correlation coefficients of some economic traits were as follows: between body weight and age at first egg, -0.354~-0.048; between body weight and number of egg production, -0.279~ -0.002; between body weight and egg weight, 0.338~0.977; between age at first egg and number of egg production, -0.791; between age at first egg and egg weight, 0.009~0.178; between number of egg production and egg weight, -0.572~ -0.256, respectively. 5.

This study was conducted to investigate the 2 week-oral toxicity of Paecilomyces sinclairii in Sprague-Dawley rats. P. sinclairii was daily administered to male and female rats for 2 weeks with different dose levels (0, 0.008, 0.04, 0.2, 1 and 5 g/kg). There were no clinical signs compared with control group, but a slight increase of white blood cell (WBC) was observed in the males rats receiving all dose levels of P. sinclairii. In biohematological analysis, the levels of glucose and cholesterol in the blood were decreased slightly in the males and females rats at doses of 0.008 or 1 g/ kg. At the all dose groups, there were no significant changes in the body weights, but autopsy findings of all organs showed reduced weights in the thymus of males in the high dose groups of 1 g/ kg and 5 g/kg. These results indicate that P. sinclairii does not induce any significant toxic effect on Sprague-Dawley rats treated for 2 weeks, but the reduced weights of thymus in males may require a further long-term investigation.

We evaluated the benign prostatic hyperplasia (BPH) with Yacon pill, the preparation composed of Smallanthus sonchifolius, Torilis japonica and Acorus gramineus. A total of 45 rats were divided into five groups. One group was used as a control and the other groups received subcutaneous injections of testosterone for 4 weeks to induce BPH. Yacon pill extract (200 or 400 mg/kg) was administered daily for 4 weeks to two groups by oral gavage concurrently with testosterone. The rats euthanized, the prostate and body weights were recorded, and tissues were subjected to hormone assay. In addition, we investigated proliferating cell nuclear antigen (PCNA) expression in the prostate using immunoblotting. Rats with BPH showed significantly increased prostate weights, increased dihydrotestosterone (DHT) levels in the serum and increased PCNA expression in the prostate; however, Yacon pill extracts treated rats showed significant reduction of prostate weights, DHT levels and PCNA expression compared with the BPH group. Conclusively, Yacon pill showed the possibility as ameliorable agents of BPH symptoms.

Objective: This study was undertaken to investigate the effects of Mori folium on insulin resistance and adipose tissue inflammation in an experimental mouse model of obesity.Methods: Obesity was induced in C57BL/6 mice by feeding them a high-fat diet. The mice were divided into four groups (n=6): a normal diet, high-fat diet, high-fat diet with 40 mg of Mori folium, and high-fat diet with 800 mg of Mori folium groups. After 13 wk, the body weights, fasting blood glucose and fasting serum insulin levels, insulin resistance (homeostatic model assessment) levels, oral glucose tolerance test levels, epididymal fat and liver weights, and gene expression of tumor necrosis factor-α, interleukin-6, and interferon-γ were measured. In addition, adipose tissue macrophages were analyzed by fluorescence-activated cell sorting.Results: Mori folium significantly reduced blood glucose levels, oral glucose tolerance levels, and liver weights. It also reduced adipose tissue macrophage numbers and tumor necrosis factor receptor-α gene expression.Conclusions: These results show that Mori folium has insulin resistance reduction and anti-inflammatory effects in an experimental mouse model of obesity.

The purpose of this study was to compare the anthropometry and nutrition knowledge, food behaviour and lifestyle of women college students with different obesity indexes. The subjects were 251 women college students who were randomly selected from Kunsan National University. The height, body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were measured, and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their Body Mass Index (BMI) : underweight, normal weight and overweight. The results were as follows. Their body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were significantly higher in the overweight subjects when compared to the underweight or normal weight subjects. Standard of living, self-recognition of health status and duration of exercise were significantly correlated with their BMIs. Self-satisfaction with body weight decreased as the BMI increased. Most subjects had poor habits such as skipping meals and lack of exercises. The overweight and the underweight groups skipped meals more frequently than the normal weight group. There were no significant differences in the scores on the nutritional knowledge and the dietary behaviour of the subjects with different BMIs. Therefore, proper nutritional education on regular meals and intervention are required if women college students are to have normal weights and healthy lifestyles.

The effect of alteration of light-darkness cycle on the protein metabolism was studied in the rat. The light-darkness cycle was altered either every 3 or 9 days, and animals consumed diets containing 8 or 25% casein. The results were summarized as follows : 1) Food consumptions and body weight gains of the 25% casein groups were higher than those of the 8% casein groups, and, among the animals consumed 25% casein diet, the light-darkness cycle altered group had lower food consumption and body weight gain than the unaltered group. 2) Weights of liver and adrenal gland per l00g body weight were not different with the dietary protein levels, but, at the end of experimental period, the 8% casein diet group of which light-darkness cycle altered every 9 days had the smallest liver weight and the largest adrenal gland weight. 3) Liver nitrogen and plasma protein concentrations of the 25% casein groups were slightly higher than those of the 8% casein groups. 4) Percentages of nitrogen retention of the 25% casein groups at period III were slightly lower in the light-darknerr cycle altered animals than that of the unaltered group.
