Objectives Osteoporosis is a common disease in adults with prevalence rate of more than 40%, and occurs more to female than to male. The purpose of this study is to identify the effect of Bia-hwan ($F{\acute{e}}i{\acute{e}}r$-$w{\acute{a}}n$) on the osteoporosis of ovariectomized rats. Methods 24 female rats were randomly assigned to a SHAM group, a control group, and a BAH group. Ovaries of the control group and the BAH group were extracted. After than, general animal feed were given to the SHAM group and the control group, animal feed contained BAH were given to the BAH group through mouths of them. After 8 weeks, rats were sacrificed and their weight, calcium, phosphorus, estradiol, total-cholesterol, triglyceride, ALP, albumin, AST, ALT, the weight of femur and tibia ash per body ratio, both area and thickness of trabecular bone, the area of osteoblast and the number of osteoclast were measured. Results The level of calcium, phosphorus, AST in the serum of the BAH group increased significantly compared to the control group. There was no significant difference between the control group and the BAH group in the level of estradiol, total-cholesterol, triglyceride, ALP, albumin, and ALT in the serum. There was no significant difference between the control group and the BAH group in the weight of femur and tibia ash per body ratio. The thickness of trabecular of the BAH group increased significantly compared to the control group, but there was no significant difference in the trabecular area. The area of osteoblast and the number of osteoclast of the BAH group decreased significantly compared to the control group. Conclusions From the results of the above study, oral intake of BAH can inhibit the decrease of calcium, phosphorus in blood and prevent the thinning process of the trabecular by suppressing activation of osteoclast. Thus, BAH may have effects on the treatment and prevention of osteoporosis.

Calcium is the most abundant stored mineral in the human body and is especially vital for bone health; thus, calcium deficiency can cause bone-related diseases, such as osteopenia and osteoporosis. However, a high concentration of serum calcium, which is commonly known as hypercalcemia, can also lead to weakened bones and, in severe cases, osteosarcoma. Therefore, it is necessary to maintain the concentration of calcium that is appropriate for bone biology. In the present study, we aimed to elucidate the effects of high concentration of calcium, approximately 2 folds the normal calcium level, on osteoblast differentiation. The CaCl2 treatment showed dose-dependent suppression of the alkaline phosphatase activity and mineralized nodule formation. Calcium showed cytotoxicity at an extremely high concentration, but a moderately high concentration of calcium that results in inhibitory effects to osteoblast differentiation showed no signs of cytotoxicity. We also confirmed that the CaCl2 treatment repressed the mRNA expression and protein abundance of various osteogenic genes and transcriptional factors. Considered together, these results indicate that a high concentration of calcium negatively regulates the osteoblast differentiation of C2C12 cells.

Background: Identifying and managing osteoporosis among cancer survivors is an important issue, yet little is known about the bone health of cancer survivors in Korea. This study was designed to measure the prevalence of osteoporosis and to assess related factors among Korean cancer survivors. Materials and Methods: This study was designed as a cross-sectional analysis. Data were obtained from dual energy X-ray absorptiometry measurement of the lumbar vertebrae and femoral neck, and from standardized questionnaires among 556 cancer survivors and 17,623 non-cancer controls who participated in the Fourth and Fifth Korea National Health and Nutrition Examination Surveys (2008-2011). We calculated adjusted proportions of osteoporosis in non-cancer controls vs. cancer survivors, and we performed multivariate logistic regression analysis. Results: The prevalence of osteoporosis among cancer survivors was significant higher than that of the non-cancer controls after adjusting for related factors. Furthermore, osteoporosis among cancer survivors was higher in elderly subjects (60-69 years : adjusted odds ratio (aOR) 3.04, 95% CI : 1.16-8.00, ${\geq}70$ years : aOR 6.60, 95% CI 2.20-19.79), in female cancer survivors (aOR: 7.03, 95% CI: 1.88-26.28), and in a group with lower monthly income (aOR: 3.38, 95% CI: 1.31-8.71). In male cancer survivors, underweight and lower calcium intake were risk factors. Conclusions: These data suggest that the osteoporosis among cancer survivors varies according to non-oncologic and oncologic factors. Effective screening should be applied, and a sufficient and comprehensive management should be matched to individual cancer survivors early after cancer treatment.

BACKGROUND/OBJECTIVES: Women's bone health status is closely related with environmental factors and lifestyle factors. The purpose of this study is to evaluate the dietary risks of osteoporosis and osteopenia for Korean postmenopausal women. SUBJECTS/METHODS: The data from 1,433 subjects from the 2010 KNHANES were used and divided into three groups: normal, osteopenia, and osteoporosis group using bone mineral density (BMD). Nutrient intakes and food intake frequency were evaluated. Logistic regression analysis was applied to determine the odds ratios for osteoporosis and osteopenia. RESULTS: The RNI percentage of each nutrient and food intake frequency from 12 food groups decreased as bone mineral density status deteriorated. Risk for osteoporosis of low calcium (Ca) intake, under the EAR, showed an odds ratio of 2.13(95% CI; 1.26-3.61, P < 0.05). Higher intake frequency showed preventive effect from osteoporosis compared to lower intake frequency in such food group as dairy products (ORs 0.40, CI 0.21-0.75), beans (ORs 0.49, CI 0.29-0.83), seaweeds (ORs 0.55, CI 0.32-0.94), fish (ORs 0.56, CI 0.32-0.98), and fruits (ORs 0.42, CI 0.23-0.79) after adjusting for age. CONCLUSION: To prevent osteoporosis in later life, sufficient Ca intake and more frequent intakes of foods containing Ca such as dairy products, beans, fish, seaweeds, and fruits, which help in Ca absorption, should be stressed for Korean postmenopausal women.

It is controversial whether low calcium intake, commonly associated with osteoporosis, results in calcium accumulation in soft tissues. This study was conducted to investigate the effects of low calcium (Ca) and oxalate (ox) intake on soft-tissue Ca deposits and bone metabolism in ovariectomized (ovx) rats. Eight week old female Sprague-Dawley rats were ovariectomized and divided into four groups. The rats were fed experimental diets containing low (0.1%, w/w) or normal (0.5%, w/w) Ca with or without sodium oxalate (1%, w/w); Sham/NCa, Ovx/NCa, Ovx/LCa, Ovx/NCa-ox, Ovx/LCa-ox for 6 weeks. All ovx rats showed a remarkable increase in body and tissue weight, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, blood urea nitrogen, alkaline phosphatase, and decreases in weight, ash, and Ca contents, as well as bone breaking force compared to those in sham rats. Serum Ca concentration was not significantly affected by dietary Ca levels or ox intake. Kidney Ca, ox acid content, and microscopic Ca deposition increased remarkably in the Ovx/LCa-ox group compared to those in the other groups. Ca content in the spleen and aorta also increased significantly, but the weight contents, Ca, bone breaking force, and Ca and oxalic acid in feces decreased significantly in the Ovx/LCa-ox group. Serum parathyroid hormone levels were not significantly different among the groups. These results indicate that low Ca intake decreased bone mineral content and increased Ca deposits in soft tissues, which was aggravated by ox intake in ovx rats. Thus, high ox intake may result in a kidney disorder in patients with osteoporosis who eat a low Ca diet.

Objectives : This study was undertaken to investigate the effects of Amydae Carapax (AC) on parameter related to bone metabolism in ovariectomized rats. Methods : We measured alkaline phosphatase activity and contents of estrogen, calcium, hydroxyproline, osteocalcin, calcitonin and parathyroid hormone after the ovariectomized rats were treated with AC for 30 days. Results : Serum estrogen, calcium and calcitonin contents in ovariectomized rats significantly decreased, but increased after AC treatment. [Significant increase of serum alkaline phosphatase activity, parathyroid hormone activity and osteocalcin content in ovariectomized rats was remarkably decreased by AC treatment. Increase of urinary calcium and hydroxyproline content in ovariectomized rats was decreased by AC treatment.] Conclusions : These results shows that AC has the ability to counteract abnormal calcium metabolic processes due to sex hormone inequality, promoting bone absorption and inhibiting bone formation.

Osteoporosis is defined as a pathologic condition in which there occurs no change in the chemical composition of the bone, while bone resorption is abnormally increased. This compares with osteogenesis, which leads to a decrease in the amount of bone. Though many varieties of therapies have been tried, no fully effective method has been found. Korean red ginseng is an important variety of Korean ginsengs and many studies have been performed to investigate its effectiveness. But there has been no report on red ginseng's effects on osteoporosis. The purpose of this study was to determine the clinical effects of Korean red ginseng on postmenopausal osteoporosis patients. The study was designed as a double-blind study. Group I consisted of 30 postmenopausal osteoporosis patients who were administered red ginseng extracts and 15 patients who were administered maltose capsules, were included in group II. The following results were obtained after one-year administration to both groups. 1. There were no significant differences in the degree of wedging, number of compression fractures in the vertebral body, trabeculations, and Cobb's angles between the experimental and control groups. 2. Even though bone mineral density increased in the lumbar spine, and decreased in the femur, there was no significant statistical difference. 3. The serum levels of parathyroid hormone (PTH), calcium, phosphate, and alkaline phosphates showed no difference between the two groups regardless of treatment. 4. Urine Deoxy-pyridinoline (DPYD) decreased in the red ginseng group while it increased in the maltose group, but statistically there was no significant difference between the two groups. 5. The clinical presentations showed no significant differences using Visual Analog Scale. 6. The specific complications related with the long-term use of red ginseng did not occur in all patients. In conclusion, there were no statistically significant differences in clinical presentations, biochemical, and radiological studies between the red gins eng and maltose groups. No definite effectiveness of red ginseng on patients with osteoporosis was found.
