The purpose of this study is to compare and analyze the bone mineral content of women who went through osteoporotic menopause and that of women who are healthy. For the purpose, this researcher sampled some women and divided them into three groups. Group 1 consisted of women who were pre-menopausal and healthy, group 2, women who were post-menopausal and health and group 3, women who went through osteoporotic menopause. The researcher measured the bone density of all the subjects and compared its difference among the three groups. Then the researcher compared and analyzed the influences of bone density on the spine among women of each group or those of all the groups. Among all regions of the spine, that of most region was spongiosa which was ovally shaped. The researcher measured the bone mineral content of spongiosa which existed in a particular section of the spine between T12 and L4. Findings of the study can be summarized as follows. The older women were, the lower their bone density was. Especially, women who had osteoporosis were significantly lower in bone density than those who were healthy. In all women, except those of group 1, bone density more and more lowered as the measured region of the spine gradually moved from T12 to L4. From a statistical view, the bone density of the entire vertebral body could discriminate the groups 1, 2 and 3. But it was not possible to discriminate between the groups 2 and 3 only with the bone density of the most interested region as mentioned above.

The present study investigated the influence of thick cortical endplates on the ultrasonic properties of trabecular bone in a femur with a high fracture risk. Twelve trabecular bone samples were prepared from bovine femurs, and acrylic plates with thicknesses of 1.25, 1.80, and 2.75 mm were manufactured to simulate the cortical endplates using acrylic with a density and a sound speed similar to cortical bone. Although the thickness of the acrylic plates attached to the two sides of the trabecular bone increased, high correlations were observed between the speed of sound and the apparent bone density of the trabecular bone, with Pearson's correlation coefficients of 0.80-0.86. High correlations were also observed between the attenuation coefficient at 0.5 MHz and the apparent bone density of the trabecular bone, with Pearson's correlation coefficients of 0.84-0.91. These results suggest that the speed of sound and attenuation coefficient at a specific frequency measured in a femur with relatively thick cortical endplates compared to the calcaneus could be used as indices for predicting the bone mineral density of the femur.

The Purpose of this study was to conduct the effects of the 12-weeks health education and exercise programs on body compositions, bone density, and blood lipid, and health behavior among middle-aged and aged women in rural areas. The number of participants was 33 women at the age of 40-75 from March 5 to May 31 in 2012. For statistical analysis, descriptive statistics, paired t-test and ANCOVA were used with SPSS WIN 12.0. The results were summarized as followings. First, body weight, BMI and % body fat decreased significantly. Second, serum total cholesterol, triglyceride and LDL-cholesterol level decreased significantly. Third, Bone density increased significantly. Forth, Health behavior and attitude were significant factors in exercise, alcohol and smoking. Therefore, it is necessary to provide individual programs of intensive aerobic and muscle exercise over 3 months and the community will have to provide systematic management.

We investigated the effect of red ginseng extracts on blood biochemical parameters, bone density and bone inorganic components etc. and data were analyzed by one-way ANOVA and Post-Hoc Test. In the results of our study, the level of albumin and HDL, Ca, P, Mg, and estradiol in blood, and the content of Ca, P, ash in femur were significantly increased in red ginseng treated group than in OVX group, and the level of ALP, AST, ALT, blood glucose, total cholesterol, triglyceride, LDL, creatinine, osteocalcin, and N-terminal telopeptide were significantly decreased in red ginseng treated group than in OVX group (p < 0.01). From these results, we knew that within the normal level, red ginseng extracts improved liver and kidney function, component of glucose and lipid in blood, bone density, bone ash and inorganic components in femur, and index related with bone metabolism.

This study was conducted to investigate factors affecting the bone density of university students in the Seoul area. Data for food habits, and dietary and health-related behavior was obtained by self-administered questionnaires. BQI (bone quality index) of the subjects was measured by a Quantitative Ultrasound (QUS). The results are summarized as follows. The average height, weight, BMI and osteopenia percentage were 175.4cm, 69.3kg, 22.5 and 15.6% for male students, and 161.5cm, 55.9kg, 21.7 and 34.1%, for female students, respectively. The mean BQI of the subjects was 110.25 (range 60.7 ～ 176.8) in male students and 90.64 (range 52.9 ～ 137.5) in female students. Height and weight were significantly related with BQI in the female group but the relationship with BMI was not significantly related with bone density in either group. BQI was positively affected by nutrition supplement in the male student group. One-side eating, diet, and intake of milk and instant food were not significantly related with BQI in males or females. The results of this study revealed that desirable food habits, dietary behavior and health-related lifestyle may have a beneficial effect on bone density. There should be established a practically and systematically organized nutritional education on optimum body weight, good eating habits, weight bearing exercise and intakes of good quality nutrient for higher bone density level.

The purpose of this study is to provide preliminary data for bone disease prevention by examining the correlation between bone mineral density, and lifestyle and nutritional status of female shift workers, at general hospitals with an irregular life cycle. The subjects for this study were 232 female shift workers, over 30 years old, who worked at a general hospital more than 5 years. From the subjects, who understood the purpose of this study and decided to be participated, we measured serum albumin, total brotein, total cholesterol, hematocrit, hemoglobin, calcium, phosphorus from blood test, and obtained bone mineral density. To analyze the effectiveness of the variables for explanation power, we established the studied values as independent variables, bone minral density as a dependent variable. Exercise, the number of drinking, calcium, and phosphorus were selected as significant variables and the explanation power was 10.2%. The bone mineral density were significantly higher at the subjects who had exercise, higher calcium and phosphorus possession, and drank alcohol than the opposite cases. Regular exercise, and 1:1 intake of calcium and phosphorous were important to prevent osteoporosis for the subjects who were working three shifts which cause irregular lifestyle.

The purpose of this study was to investigate effect of resistance training on BMD and bone metabolism related markers in aging rats. Thirty male Spraugue-Daweley rats were divided into sedentary (CON; n=10 ) non-load resistance trained(NLRTG; n=10), and load resistance trained(LRTG; n=10) groups at the age of 64 weeks. The rats in the resistance training groups((NLRTG and LRTG) performed the tower climbing exercise 4 times a week. The LRTG groups were conditioned to climb a vertical ladder with weights appended to their tail 4 days/wk for 12 wks. After 12 weeks of exercise, serum osteocalcin, bone mineral density (BMD), breaking force, ash, Ca, and P in the femur were measured. After training, serum osteocalcin (OC) was significantly (p < 0.05) higher in both LRTG and NLRTG when compared to Control. Right femur BMD was significantly (p < 0.05) greater for LRTG when compared to both NLRTG and Control with no significant difference between NLRTG and Conrtol. The breaking force of femur was significantly (p < 0.05) greater for LRTG and NLRTG when compared to Control. The Ash, Ca, content of femur were significantly increased in resistance training groups than control group. These results suggest that the increase in bone mineral density induced by resistance training is mediated by changes in bone microarchitecture as well as training intensity and osteocalcin.
