This study was designed to investigate the effects of caffeine intake on Ca and P metabolism in ovariectomized rats. For this purpose, the ovariectomized female rats weighing 230.8$\pm$3.5g were divided into four groups, eight rats each ; control, low caffeine(LC), medium caffeine(MC)and high caffeine(HC) groups. They were supplied for six weeks with the caffeine of 0mg, 66.8mg, 167mg and 334mg per kilogram of diet, respectively, and the results are summarized as follows. 1) There were no significant differences in feed intake, feed efficiency ratio and body weight change among all of experimental groups. But liver weight(both total weight and weight/body weight) was significantly decreased by caffeine in MC group. 2) The weight of tibia was decreased by caffeine intake in MC and HC groups. But the length, Ca and P content of tibia and femur was not changed in all of caffeine groups. 3) Ca, PTH and calcitonin levels in serum were not affected by caffeine. While, serum P level in HC group was significantly increased as compared with the control. 4) The fecal excretion of Ca and P tended to be higher in the caffeine groups, and as the result, the absorption rate, retention and retention rate of Ca and P tended to be decreased. It was noteworthy that P retention was significantly lowered in HC group as compared with LC group. The results showed that, when caffeine was taken by ovarietomized rats, the weight of tibia was decreased and the retention rate of Ca and P tended to be lowered. Therefore, too much intake of caffeine for women whose bone mineral density of tibia is decreased after postmenopause seems to accelerate the decrease of bone mineral density due to the negative effect on metabolism of Ca and P.

Purpose: We analyzed climacteric symptoms, bone mineral density (BMD), serum estradiol ($E_2$) and follicle stimulating hormone (FSH) to identify the health benefits of meridian massage in perimenopausal women. Methods: There were 16 women in the experimental group and 17 people in the control group. Meridian massage was performed for 4 weeks, 3 times a week for 20 minutes each session. The data were collected pre-treatment, posttreatment and 4 weeks after treatment. SPSS/WIN 11.5 was used for data analysis. Results: After meridian massage, there were significant differences in climacteric symptoms (U = 65.50, p = .011) and BMD (U = 65.50, p = .011) between the two groups. The E2 level showed a significant difference between the two groups pre- and posttreatment (U = 75.00, p = .028). FSH showed a significant increase when measured at 4 weeks after the treatment as compared with the amount when measured post-treatment within the control group (z = -2.249, p = .025), experimental group showed a stable change in FSH. but there was no significant difference between the groups. Conclusion: In this study, we confirmed the effects of Meridian massage in decreasing climacteric symptoms, inhibiting the decrease of BMD and stabilizing serum hormone in perimenopausal women. Therefore, it can be considered for use as a nursing intervention for health management in perimenopausal women.

This study was conducted to investigate the factors which are related to Bone Mineral Density(BMD) of female for prevention of osteoporosis. We measured the BMD of lumbar spine(L2-L4) and femoral neck in 4802 female, using dual energy X-ray absorptionmetry(DEXA; DPX-alpha. Lunar, U.S.A.). and then analysed the 9 factors-age group, body mass index(BMI), amount of smoking, drinking, exercise, sleep, and fast blood sugar-which are related to BMD of female. The following results were obtained : 1. In age group, T-score was the highest at 36－42(六七) years group in lumbar spine(L2-L4) and at 15－21(三七) years group in femoral neck. and then it was decreased rapidly after 43－49(七七) years group in both lumbar spine(L2-L4) and femoral neck. Therefore we concluded that T-score of female in lumbar spine(L2-L4) and femoral neck change according to age group in $\ll$Hwangjaenaekyong Somun; 黃帝內經 素問$\gg$. 2. In BMI, T-score of lumbar spine(L2-L4) and femoral neck were increased according to BMI increase. 3. In amount of drinking and smoking, T-score was highest in heavy groups(women who have drunk soju more than 4 bottles for a week) in both lumbar spine(L2-L4) and femoral neck. But there t was no significant difference in comparison according to age group. 4. In exercise, T-score was higher in exercising group than non exercising group. And it appeared that women who have taken proper exercise had higher T-score than women who have taken exercise daily. 5. T-score was higher in women who ordinarily sleep well in both lumbar spine(L2-L4) and femoral neck than sleep badly. And there was significant difference in 43-56 years group. 6. T-score was low in the group that exceed 110mg/dl in fast blood sugar. Conclusions : The age group in $\ll$Hwangjaenaekyong Somun; 黃帝內經 素問$\gg$ is related to BMD of women. And risk factors-BMI, exercise, sleep, fast blood sugar, thyroid disease-are related to BMD of women. Therefore we expect that this study will help for prevention of osteoporosis of women, and further study will be achieved.

Purpose: The aim of this study was to observe the bony change in the OVX rat longitudinally and to study the alendronate effect. Materials and Methods: Eighteen Sprague-Dewley rats, eight-week old each, were randomly assigned into three groups: one of those sham-operated (N=4), the other two were OVX: saline-treated (N=7) and alendronate-treated group (N=7). The saline-treated group was administered with saline solution (0.1mL/100g) daily, while the alendronate-treated group was given alendronate (1mg/kg, Sigma-Aldrich Corp. Korea) daily. Micro-CT scannings of the lumbar were consecutively done at baseline, at 3-week intervals during 9 weeks. Two and three dimensional bony analysis were done. Bone mineral density (BMD) was measured with Piximus (GE Lunar Co. USA). The average values of these three methods were compared with each group. Results: After 6 weeks the BMD of the OVX group showed lower tendency than that of sham group. After 6 weeks many 3D parameters of micro-CT showed higher values in the OVX-alendronate group compared with the OVXsaline group. Most 2D bony parameters were higher in the OVX-alendronate group compared with the OVX-saline group at 9 weeks. Conclusion: This study showed low BMD of the OVX group after 6 weeks and showed the effect of alendronate on the BMD and bony structures of ovariectomized rats. This study also showed usefulness of in vivo micro-CT in monitoring individual bone changes over time.

In our study, osteoporosis was induced by ovariectomized in female Sprague-Daweley rats, and the prevention and treatment efficacy of the climacteric disease the postmenopausal Type I pattern was examined by using the experimental substance soybeans and arrowroot. After ovariectomy; the amount of estrogen was found to be reduced by 21.37$\%$ and it showed the tendency to be increased by 4.49$\%$ in T1 (extraction of soybeans group) and 7.62$\%$ in T2 (extraction of ferment soybeans group). The change of bone density, 14 weeks after ovariectomy in the femur, was decreased by 9.33$\%$ in N.C. group, and 5.46$\%$ in T3 (extraction of ferment arrowroot group). As pathological findings, the trabeculae of femur were detected to be abundant as normal and the frequency of the appearance of osteoclasts was very minimal. In the T3, the frequency of the appearance of the trabeculae of femur was increased to the level that could be distinguished. In regard to the accumulation of lipid in the bone marrow, the accumulation of lipid in the bone marrow was low as normal. However, in T3, the decrease to the level that could be distinguished was detected. In addition, in regard to the pathological findings of the uterus, normal uterine tissue findings were detected. In the T3, the minimal atrophy findings were detected. In conclusion, when the T3 was orally administered continuously for 14 weeks, it was thought that a certain proportion of the hormonal balance was maintained that functioned as a substance interfering the accumulation of fat, and it was considered to be of help in the treatment of not only osteoporosis Type I, but also for the prevention and treatment of various endocrinal diseases.

Estrogens are critical to the functioning and maintenance of a diverse array of tissues and physiological systems in mammals. The actions of estrogen on such classical targets as the reproductive tract, gonads, mamary tissue, and hypothalamic/pituitary axis have been well characterized. A role in nonreproductive tissues, such as maintenance of bone mineral density and cardiovascular health in woman, as has been described. There were ne significant differences in the average of body weights, testis weights, among the experimental groups. The lumen of rate testis began to dilate from the day 8 and continued to the 59 post-treatment. The average diameter of dilate of rate testis in ICI 182,780 treated group increased 2.3-fold compared to the control group. Epithelical cell height in the rate testis of the treated mice decreased all the time periods, compared to the control.
