Objectives : This study was conducted to investigate how Bone Mineral Density(BMD) and bone mass index(BMI) differ according to classification of blood pressure which JNC 7(The seventh report of the joint national committee on prevention, detection, evaluation and treatment of high blood pressure) indicated. Methods : We measured BMD and BMI of lumbar spine($L_2-L_4$) and femoral neck of 9816 people, and then we analyzed them according to classification of blood pressure. Results : The number of prehypertension group was the most, and Stage 2 hypertension group was the least. As the hypertension was increasing, BMD of lumbar and femoral neck were decreasing, and BMI was increasing. In men, as the blood pressure was increasing, BMI was increasing. But the BMD was irrelevant. In women, the distribution was similar to the total. Conclusions : As the hypertension was increasing, BMI was increasing and BMD was decreasing. And it was more remarkable in women.

Objective : To identify the risk factors for postmenopausal osteoporosis in Korea Materials and methods : Bone mineral density (BMD) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry in 808 apparently normal postmenopausal Korean women. Questions about life style, demographic parameters, medical history and social habits etc. were asked on these women; 2ll women with normal bone mineral density, and 597 women with osteopenia or osteoporosis. Results 'Age of >50 years, low body mass index (BMI; <18.5 kg/m2), long duration of menopause(>10 years), and previous history of fracture were associated with increased prevalence of osteopenia or osteoporosis. Women without the outside activity also showed a higher frequency of low bone mass, Risk for osteopenia or osteoporosis was low in women with high BMI (>23 kg/m2) and women with job. The prevalence of low bone mass appeared to be independent of the following parameters: socioeconomic status, familial history, smoking, drinking, exercise, previous use of oral contraceptive, coffee or milk consumption, and degree of sunlight exposure. Conclusion 'Age, BMI, duration of menopause, previous history of fracture and degree of outside activity are the risk factors for postmenopausal osteoporosis in Korea.

Purpose: This study was performed to assess the relationships among bone mineral density, dietary habits, life styles and anthropometric measurements in young women. Subjects included 229 female college students in Seoul and Kyunggi province. Method: The subjects were asked about dietary habits and life styles using questionnaire. A sampel of 229 young women was assessed anthropometric measurements and bone mineral density on calcaneous using quantitative ultrasound. Result: The percentages of the osteoporosis(T-score<-2.5), osteopenia(-2.5${\leq}$T-score<-1.0), and normal(T-score${\geq}$-1.0) groups were 1.75%, 13.53% and 84.71%, respectively. Weight, soft lean mass, and BMI were positively related with T-score and Z-score. But height was negative related with SOS(Speed of sounds). Conclusion: This study confirmed that one of the most effective ways to minimize bone mineral density less in young women is to maintain an adequate body weight, soft lean mass, and BMI. And the young women were recommended do not one-side eating, daily intakes of milk products, perform daily physical exercise, and do not drink coke or soft drinks for the bone health.

Objectives : To investigate the factors affecting bone mineral density in across stratified postmenopausal ages. Methods : Data from 1,698 subjects who completed the 2010-2011 National Health and Nutrition Survey were analyzed using SPSS Statistics 21.0 The $x^2$ test and one way (ANOVA) were used to verify the relationship between general characteristics and health behaviors and the prevalence of osteoporosis. Logistic regression analysis was used to verify the factors Influencing bone mineral density. Results : The bone mineral density distribution was the highest among those with osteopenia, with proportions of 21.8% in healthy subjects, 58.1% in osteopenia, and 20.0% in those with osteoporosis. The distribution of osteoporosis by age group was 5.2% among subjects in their 50s, 15.4% among those in their 60s, and 42.4% among those in their 70s. In multivariate logistic regression analysis, the prevalence of osteoporosis according to ages was significantly correlated with age, educational level, body mass index(BMI), and parity 4 of more than 1-2 babies. Conclusions : Although age is an uncontrollable factor in the prevention of osteoporosis, educational level and BMI are correctable factors to maintain bone mineral density. There is a need to maintain healthy BMI and expand osteoporosis prevention education.

Purpose: To evaluate physical characteristics, lifestyle related to bone-health, and bone mineral density (BMD) in mothers and their daughters and to determine the predictors of BMD. Method: BMDs at the forearm, lumbar spine, and femur were measured in 101 healthy, mother-daughter pairs by dual energy X-ray absorptiometry. Mother-daughter differences between general characteristics, means for BMDs were assessed by ${\chi}^2$-test, t-tests. Multiple regression analyses were used to identify predictors of BMD in each group. Results: Mothers had significantly higher BMD than their daughters at forearm, lumbar spine, and femur. The predictors of mothers' BMDs were body weight, body mass index (BMI) and percentage body fat, explaining 5.1~31.6% of the variation in BMDs. BMI, percentage body fat and their mother's BMD of the corresponding site bone were predictors in daughters, explaining 17.5~31.6% of the variations in BMDs. Conclusion: These results indicate the importance of weight on bone that the BMDs seems to be related to fat free mass both in young-adult daughters and in middle aged mothers. These also suggest the importance ofintervention for the development of BMD in daughter of mother with low BMD.

Soy isoflavones have been suggested to improve bone loss and lipid profile in postmenopausal women and ovariectomized rats. In present study, we investigated the hypothesis that consumption of soybean, mung bean, cowpea and azuki bean has a beneficial effect on lipid profile which associates with bone mass in ovariectomized rats. Forty two female Sprague-Dawley rats were either sham-operated (Sham) or surgically ovariectomized (OVX). Sham and OVX groups were fed a regular AIN-93M diet, but ovariectomized rats with soybean (OS), mung bean (OM), cowpea (OC) or adzuki bean (OA) were fed AIN-93M diet replacing 35% of corn starch with powdered OS, OM, OC or OA for 10 weeks. Total- and LDL-cholesterol concentrations were significantly lower in Sham and OC groups than other OVX groups. There was significant negative association between total cholesterol concentration and bone mineral density (BMD) of tibia in only OC group. In conclusion, total-cholesterol concentration was significantly and negatively correlated with BMD in rats consumed cowpea, suggesting that the reduced cholesterol concentration may have a beneficial effect on bone mass.

We identified osteoclast-derived SLIT3 as a new coupling factor using fractionated secretomics. Coupling links bone resorption to bone formation. SLIT3 stimulated the recruitment and proliferation of osteoblasts into bone remodeling sites via activation of ${\beta}-catenin$. Autocrine signaling by SLIT3 also inhibited bone resorption by suppressing the fusion and differentiation of pre-osteoclasts. All mice lacking Slit3 or its receptor Robo1 showed an osteopenic phenotype with low bone formation and high bone resorption. A small truncated recombinant SLIT3 protein increased bone mass in an osteopenic mouse model. These results suggest that SLIT3 is a novel therapeutic target in metabolic bone diseases.

Bone scan is one of the most frequently peformed studios in nuclear medicine. In bone scan, the amount of radiolsotope taken up by lesion depends primarily on the local rate of bone turnover rather than on the bone mass. Bone scan is extremely sensitive for defecting bony abnormalities. However, abnormalities that appear on bone scan may not always represent disease. The normal scan appearances may be affected not only by skeletal physiology and anatomy but also by a variety of technical factors which can influence image quality. Many normal variants and artifacts may appear on bone scan. They could simulate a pathologic process and could mislead into the wrong diagnostic interpretation. Therefore, their recognition is necessary to avoid misdiagnosis. A nuclear medicine physician should be aware of variable appearance of the normal variants and artifacts on bone scan. In this article, a variety of normal variants and artifacts mimicking real pathologic lesion in bone scan interpretation are discussed and illustrated.

The case report of migrating ingested fish bone presenting as an unresolving inflamed neck mass is rare. The diagnosis must be suspected in a patient with an unresolving inflamed cutaneous lesion, especially one with a punctum, the tenderness of the lesion elicited on swallowing and the presence of a palpable subcutaneous neck mass. In such a patient, a history of recent foreign body ingestion must be actively sought. An accurate early diagnosis of this easily treatable condition is desirable because it could avert unnecessary delays, inconveniences, anxiety, costs, and surgery. The authors experienced a case of lateral neck mass resulting from the migration of a fish bone which was successfully removed by surgical exploration and made a report with a review of literature.
