This study was performed to evaluate the effect of red-yeast-rice on blood lipids and also to investigated the relation of blood lipids, bone related hormones, and bone mineral density in overiectomized rats. Forty female rats (body weight $210\pm5$g) were divided into two groups. The rats in the first group were ovariectomized which the others received sham operation (SHAM). And then each rat group was further divided into control diet $(casein\;20\%)$ and red-yeast-rice powder supplemented $(0.1\%)$ diet group. All rats were fed on experimental diet and deionized water ad libitum for 9 weeks. Bone mineral density (BMD) and bone mineral content (BMC) were measured using PIXImus in spine and femur. Bone formation and bone resorption were measured by serum osteocalcin and urinary deoxypyridinoline (DPD) crosslinks value. Serum growth hormone, IGF-1 and calcitonin were analyzed using radioimmunoassay kits. The red-yeast-rice group had significantly lower the blood triglyceride concentration and had lower the blood total cholesterol concentration than casein group did in ovariectomized rats. And the red-yeast-rice group than casein group in ovariectomized rats. The red-yeast-rice group had significantly lower the atherogenic index than control group within the ovariectomized groups. In the experimental rats, serum total cholesterol concentration was negatively correlated with femur BMC and crosslink value. Crosslink value was negatively correlated with spine BMC and IGF-1. Osteocalcin concentration was negatively correlated with crosslink value. Growth hormone was negatively correlated with crosslink value and positively correlated with spine BMC. The findings of this study suggest that red-yeast-rices are beneficial for blood lipid in ovariectomized rats. And when considering a population-based public health approach to lowering cholesterol and bone loss, and preventing coronary heart disease and osteoporosis, the red-yeast-rice dietary supplement could provide a new approach for the maintenance of healthier cholesterol and bone.

This study was done to evaluate the effectiveness of dietary calcium level(a diet which met 100% or twice the calcium level in AIN-76 diet) on preventing bone loss in ovariectomized rats. Forty female Sprauge-Dawley rats(body weight 200$\pm$5g) were divided into two groups. One group were ovariectomized(Ovx) while the others received sham operation(Sham). Thereafter, each rat group was further divided into normal calcium diet(NCD, 0.52%) and high calcium diet(HCD, 1.04%) sub-groups. All rats were fed on experimental diet and deionized water ad libitum for 8 weeks. Urinary pyridinoline & creatinine and serum estradiol, luteinizing hormone, calcium, phosphate, total protein, albumin, alkaline phosphatase and osteocalcin were determined. There were no significant differences in serum calcium. total protein and albumin in the two groups(Ovx vs Sham) of rats. Ovariectomized rats had significantly lower estradiol than sham operated rats. There was a highly significant correlation between total bone mineral density(TBMD) and overall level of esteradiol(r=0.59, p<0.05). Total bone mineral density did not correlate significantly with ALP or osteocalcin, although a negative trend was evident. However, the rats fed high calcium diet had a lower crosslinks value and osteocalcine than the rats fed normal calcium diet. An increased rate of bone turnover is usually associated with a decrease in bone mass bexause bone formation at each remodeling site is never as great as resorption. Ovariectomized rats fed high calcium diet had a lower crosslink value and osteocalcin; it means high cacium diet decreased bone turnover rate. The findings from the present study demonstrated that bone loss due to ovarian hormonal deficiency can be partially prevented by a high calcium diet. Futhermore, these findings support the strategy of the use of a high calcium diet in the prevention of estrogen depletion bone loss (postmenopausal osteoporosis).

This research aims to test a new drug candidate based on a traditional medicinal herb, F1, an herbal extract obtained from Astragalus membranaceus and its main ingredient, 1-monolinolein that may have fewer side effects and less uterine hypertrophy. In vitro experiments, human osteoblast-like cell lines, MG-63 and Saos-2, were analyzed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and an alkaline phosphatase (ALP) assays. Mouse osteoclasts were induced through a calcium-deficient diet and inhibition effects were measured. In vivo experiments were done using ovariectomized (OVX) rats for 9 weeks. At necropsy, uterus weights were measured, trabecular bone area (TBA) of tibia and lumbar vertebra were measured bone histomorphology. In results, cell proliferation and ALP activity in Saos-2 by ether F1 or 1-monolinolein did not increased significantly compared to the control. The F1 inhibited osteoclast development ($IC_{25}=3.37{\times}10^{-5}$mg/mL) less than 17$\beta$-estradiol. The OVX rats administered F1 (2 mg/kg/day and 10 mg/kg/day) showed an increase in TBA of the tibia significantly (136.3${\pm}4.2% and 138.5{\pm}$10.3% of control). In conclusions, the herbal extract, F1 inhibited tibia and lumbar bone loss and did not cause uterine hypertrophy. However, 1-monolinolein, the main ingredient of the herbal extract, did not inhibit bone loss.

This study conducted a secondary analysis by using original data of performed by Korea Institute for Health and Social Affairs to determine factors affecting doctor's diagnosed disease-related mental health for the elderly aged over 65 years living in Korea. The survey was conducted in 2007 and it evaluated finally 720 cases by excluding cases with no answer or a wrong answer. The results were as follows. The proportion of the elderly who stress cognition was influenced when subjects were female and older, lower subjective health condition and osteoporosis, showed statistically significant difference. The proportion of the elderly who experience depression was influenced when subjects were older, had not health insurance or medical care, and lower subjective health condition, showed statistically significant difference. The proportion of the elderly who have suicide thoughts was influenced when subjects were female and higher educational background, lower subjective health condition, COPD(Chronic obstructive pulmonary disease), and diabetes mellitus, showed statistically significant difference. We knew that the relationship between diseases and depression in the elderly influenced on the depression about most of the diseases. Particularly, Depression and suicide had a high correlation. The results suggest that it should be necessary to systematic management of diseases in the depression treatment of the Elderly in Korea.

Background: The purpose of this study was to investigate the clinical and radiological outcomes of locking plate fixation with fibular strut allograft to manage unstable osteoporotic proximal humerus fractures. Methods: We retrospectively reviewed 15 patients who underwent open reduction and locking plate fixation with fibular strut allograft for osteoporotic proximal humerus fracture between July 2011 and June 2015. For functional evaluation, we evaluated visual analogue scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) shoulder score, and active range of motion. For radiological evaluation, shoulder true anteroposterior (AP) and AP in $20^{\circ}$ external rotation, as well as the axillary view were taken at two weeks, six weeks, three months, six months, and one year. And the neck-shaft angle was measured on the AP view in $20^{\circ}$ external rotation view. Results: At the one-year follow-up, mean VAS pain score and all shoulder scores, including ASES score and UCLA shoulder score, exhibited satisfactory clinical outcomes. All patients obtained bone union between three and six months post-procedure. Moreover, the mean immediate postoperative neck-shaft angle was $138^{\circ}{\pm}4^{\circ}$, and at one-year follow-up, the neck shaft angle was $137^{\circ}{\pm}5^{\circ}$. There was no significant difference between the preoperative and postoperative values (p=0.105). Conclusions: For the unstable two-part and three-part osteoporotic proximal humerus fractures with medial calcar comminution, the use of fibular strut allograft with locking plate fixation was effective in maintaining the initial status of reduction and exhibiting the satisfactory functional and radiological outcomes.

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.

Osteoclasts play a critical role in bone-related diseases such as osteoporosis and rheumatoid arthritis by resorbing the bone. Recently, natural products from plants have been extensively studied as therapeutic drugs to treat and prevent various diseases. Here, we examined the effects of rhizoma arisaematis on ostoclast differentiation and bone resorption. We showed that rhizoma arisaematis significantly suppressed receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation in bone marrow-derived macrophages (BMMs) in a dose dependent manner but have little or no effect on the cytotoxicity of BMMs and RAW264.7 cells. We found that rhizoma arisaematis iarrow-ed the RANKL-induced c-Fos and nuclear factor of activated T cells (NFAT)c1, which is a master regulator of osteoclast differentiation. Furthermore, rhizoma arisaematis suppressed the mRNA expression of tartrate resistant-acid phosphatase and cathepsin K iaduced by RANKL in BMMs. in y chanistic studies, rhizoma arisaematis considerably iarrow-ed I-${\kappa}B$ degradation, which is a negative regulator of NF-${\kappa}B$, but iaduced the phosphderlation of p-38, ERK, and JNK.MMlso, we found that rhizoma arisaematis significantly iarrow-ed osteoclastic bone resorption. Taken tarether, our results suggest that rhizoma arisaematis suppresses osteoclast differentiation through down-regulatd the mRANKL-induced c-Fos and NFATc1 expression and iarrow-s bone resorption.

PURPOSE: Estrogen replacement therapy is indicated for the relief of hot flushes and urogenital atrophy, the prevention of osteoporosis and the reduction in risk of cardiovascular disease. The present study assessed by blood pressure, heart rate variability, and climacteric symptoms in menopausal women before treatment and at 1 month during estrogen replacement therapy. METHODS: The study sample consisted of 16 healthy menopausal women (range 49 to 59 years, mean : 53.4 years) attending menopausal clinics for the complaint of climateric symptoms at S. hospital in Chunchoen. They were all non-smokers and no patient had symptoms or evidence of cardiovascular disease. They took estrogen replacement therapy (conjugated estrogen 0.625 mg with or without medroxy progesteron 2.5mg) for 1 month. Blood pressure, heart rate variability(heart period and vagal tone) through ECG, and climacteric symptom were measured in all subjects before treatment and at 1 month during treatment. Climacteric symptom questionnaire which was developed by Neugarten et al.(1963) was modified with 20 items of question(Cronbach's alpha = 88 -.89). The data was collected from Sept. 1. 2000 to July. 30. 2001. RESULTS: There was no significant difference in mean systolic and diastolic pressure between the baseline and at 1 month during treatment. The mean heart period and vagal tone were slightly increased, but difference of mean heart period and vagal tone were not statistically significant between the baseline and at 1 month during treatment. The score of climacteric symptoms decreased significantly from the baseline after treatment. CONCLUSIONS: Even though, this study did not show that estrogen replacement therapy led decrease of blood pressure and increase heart rate variability, climacteric symptoms reduced much in all subjects after taking drugs. These results suggest that there is need to repeat study with long term period.

Sexual health education for the patients is an independent function as well as a professional responsibility of nurses. Education should be based on the needs of patients in order to be successful and effective. Therefore nurses must identify sexual health education needs of their patients. A sexual health education protocol for hysterectomy patients was developed by the researcher for this study and included physiosexual and psychosexual topics as well as the topic of sexual interaction. The subject pool was composed of 108 post op total hysterectomy patients who had undergone doing a hysterectomy 5 to 10 days previously at 5 hospitals located in the Seoul and Kyunggi-do area from July 23 to September 30, 2001. The questionnaire was composed of 60 items on sexual health education and used a Likert-type 4-point scale. Internal consistency of this questionnaire in this study was cronbach's $\alpha$=.9495 for sexual health educational needs. For data analysis, the study executed a t-test, ANOVA, and Duncan's Test, in accordance with the purpose of the study using SPSS/PC Win 10.0. The results were as follows: The need for education was highest in the psychosexual area (3.38 point) with education related to sexual interaction the lowest (3.20 point). Osteoporosis (3.75 point) was ranked overall as the highest area of educational need. The degree of educational need varied in correlation with other characteristics of the patients including age, status of marriage, duration of marriage, religion, academic career, monthly income, occupation, the number of children age of menarche, menstruation, other diseases except gynecological disease, previous genital organ operation experience, disease discovery method, pre-explanation for the hysterectomy, average sexual intercourse frequency, how to acquire sexual health information and previous sexual health education (p<.05). In conclusion, the degree of sexual health education needs of hysterectomy patients was very high. Therefore, sexual health educational programs planned according to characteristics of the participating women is necessary.
