Osteoporosis is a systemic skeletal disease caused by low bone mass and the decrease of bone density in the microstructure of trabecular bone. Drug therapy(PTH Parathyroid hormone) may increase the trabecular thickness and thus bone strength. Vertebroplasty is a minimally invasive surgery foy the treatment of osteoporotic vertebral compression fracture. This Procedure includes Puncturing vertebrae and filling with Polymethylmethacrylate(PMMA). Although altering recommended monomer-to-Powder ratio affects material properties of bone cement, clinicians commonly alter the mixture ratio to decrease viscosity and increase the working time. The Purposes of this study were to analyze the effect of 4he monomer-to-powder ratio on the mechanical characteristics of trabecular. In this paper, the finite element model of human vertebral trabecualr bone was developed by modified Voronoi diagram, to analyze the relative effect of hormone therapy and vertebroplasty at the treatment of osteoporotic vertebrae. Trabeuclar bone models for vertebroplasty with varied monomer-to-Powder ratio(0.40∼1.07 ㎖/g) were analyzed. Effective modulus and strength of bone cement-treated models were approximately 60% of those of intact models and these are almost twice the values of hormone-treated models. The bone cement models with the ratio of 0.53㎖/g have the maximum modulus and strength. For the ratio of 1.07㎖/g, the modulus and strength were minimum(42% and 49% respectively) but these were greater than those for drug therapy. This study shows that bone cement treatment is more effective than drug therapy. It is found that in vertebroplasty, using a monomer-to-powder ratio different from that recommended by manufacturer nay significantly not only reduce the cement's material Properties but also deteriorate the mechanical characteristics of osteoporotic vertebrae.

Purpose : The objective of this study was to evaluate the effects and adverse side-effects of growth hormone (GH) therapy in children with Prader-Willi syndrome (PWS). Methods : Forty-one patients who had been treated with GH for more than two years (24 boys and 17 girls, mean age $7.3{\pm}3.3$ years during treatment initiation) were enrolled for this study. Results : After 2 years of GH therapy, the height and weight standard deviation scores (SDS) increased significantly ($-1.19{\pm}1.37$ vs. $-0.02{\pm}1.45$, and $1.02{\pm}2.42$ vs. $1.63{\pm}2.22$, P<0.002); however the percentage body fat decreased ($44.6{\pm}9.9%$ vs. $38.1{\pm}10.5%$, P<0.001). Further, no change was observed in the thyroid and serum glucose levels, but the total cholesterol level decreased. GH therapy did not impact glucose control in the patients with diabetes. The most common adverse effects of GH therapy were the progression of scoliosis and adenoid hypertrophy. Conclusion : GH therapy improved the height SDS and body composition in patients with PWS. However, GH should be used with caution in patients with scoliosis and adenoid hypertrophy.

For the evaluation of hormonal control of spermiation in fish, a method to quanify the spermiation response or mature Rhynchocypris oxycephalus (Sauvage and Dabry) to hormonal therapy is described. Spermatocrit was determined after 7 min centrifugation at 18,000 $\times$ｇ and sperm density was estimated by a standard hemocytormer method. Sperm density can be predicted from spermatocrit since their relationship is linear as described by the regression equation, Y=3.68X-27,18 ($R^2$=0.82, N=50), where Y is spermatocrit and X is sperm density. Milt production by mature R. oxycephalus was highest at 24 h after injection of 1,000 IU human chorionic gonadotropin (HCG) and 50 $\mu\textrm{g}$ luteinizing hormone-releasing hormone analogue (LHRHa) per kg body weight. Increased milt production coincided with low spermotocrit and sperm density levels. These results demonstrate that spermition in mature R. oxycephalus can be reliably evaluated by a spermatocrit method and that HCG and LHRHa are effecove in stimulating of spermiation in this species.

Objectives: The purpose of this health promotion project for Korean medicine is to promote the health of climacteric women in Boeun-gun. Methods: During the project, pressure needle acupuncture treatment, herbal medicine treatment, meditation pore therapy, and health education were conducted. To evaluate the results, basic health surveys (body height, body composition test, blood pressure etc.), female hormone tests, Kupperman's index (KI), Menopause-specific quality of life questionnaire (MENQOL), and Perceived stress scales (PSS) were conducted. Results: No significant change was observed in the body composition test and blood pressure after the project. Follicle stimulating hormone (FSH) was significantly increased after the project, but Luteinizing Hormone (LH) and total estrogen levels were not significantly changed. KI and MENQOL scores significantly decreased after the project, and significantly decreased in 4 out of 11 items of KI and 3 out of 4 domains of MEMQOL. No significant change was observed in the PSS score after the project. Conclusions: From the results of this project, it can be seen that the Korean medicine health promotion project can help alleviate symptoms of climacteric syndrome and postmenopausal syndrome.

Background: Reproductive cancers are those that affect the human organs that are involved in producing offspring. An attempt is made in the present communication to assess the magnitude and pattern of reproductive cancers, including their treatment modalities, in India. The cancer incidence data related to reproductive cancers collected by five population-based urban registries, namely Bangalore, Bhopal, Chennai, Delhi and Mumbai, for the years 2006-08 were utilized. The reproductive cancers among females constituted around 25% of the total and around 9% among males. Among females, the three major contributors were cervix (55.5%), ovary (26.1%) and corpus uteri (12.4%). Similarly among males, the three major contributors were prostate (77.6%), penis (11.6%) and testis (10.5%). For females, the AAR of reproductive cancers varied between 30.5 in the registry of Mumbai to 37.3 in the registry of Delhi. In males, it ranged between 6.5 in the registry of Bhopal to 14.7 in the registry of Delhi. For both males and females, the individual reproductive cancer sites showed increasing trends with age. The leading treatment provided was: radio-therapy in combination with chemo-therapy for cancers of cervix (48.3%) and vagina (43.9%); surgery in combination with chemo-therapy (54.9%) for ovarian cancer; and surgery in combination with radio-therapy for the cancers of the corpus uteri (39.8%). In males, the leading treatment provided was hormone-therapy for prostate cancer (39.6%), surgery for penile cancer (81.3%) and surgery in combination with chemo-therapy for cancer of the testis (57.6%).

Breast cancer primary prevention is a high research priority due to the high psychological and economic costs. The disease is a multistep process and several risk factors have been recognized. Over the past three decades numerous studies have investigated the association of lifestyle with breast cancer, showing independent effects of various factors. We report here a summary of the present state of knowledge on the role of lifestyle patterns, such as physical activity, diet, smoking, hormone therapy, and experience of psychological stress in the modulation of breast cancer in women, and discuss commonly accepted biological mechanisms hypothesized as responsible for the associations. The findings indicate that regular physical activity of moderate to vigorous intensity is probably linked with the decreased breast cancer risk among postmenopausal females and suggestive for a decrease of the risk in premenopausal women. In contrast, the consumption of high-fat diet, alcohol intake, and use of combined estrogen and synthetic progestagen hormonal therapy may increase the risk. Epidemiological findings dealing with a role of smoking and experience of psychological stress are conflicting.

Isoflavones are reported to playa role in menopausal women as a phytoestrogen, which can replace estradiols in hormone replacement therapy (HRT). Recently; due to the risk of breast cancer by HRT, phytoestrogens (e.g. isoflavones) have been focused as an alternative therapy in menopause. In the study, we investigated whether isoflavones derived from Sophorae fructus (SISO) have more benefit than that of soybean isoflavones in estrogen deficient rats. We found that SISO effectively controled $H_2O_2$ comparing with the baseline (p<0.01 vs. post value of OVX-Cont), and the blood sugar and weight were also controlled with decreasing patterns. Additionally, in LDH assay for cytoprotective effect in Neuro-2a cell line, SISO protected cells from the damage by SNAP (p<0.05). In conclusion, SISO may have more beneficial effect in enhancing the menopausal signs than that of soybean isoflavones and the cytoprotective effect in neuron cells suggests that SISO can play a certain role in neuroprotection after menopause.

This retrospective study aimed to investigate whether there was a difference in the success rate of removal of residual thyroid tissue in patients with the same cutoff serum thyroglobulin (Tg) value-measured 2 weeks after thyroid hormone withdrawal (THW)-for different radioactive iodine (RAI) activities. We identified 132 patients with papillary thyroid cancer who were treated with total thyroidectomy and RAI therapy to evaluate the efficacy of three radioactivities of I-131: 1,110, 3,700, and 5,550 MBq. Serum Tg testing was performed 1 week before RAI treatment and 2 weeks after THW (pre-Tg); the cutoff pre-Tg level was below 10 ng/mL. Stimulated Tg levels were measured on the day of I-131 administration (off-Tg). After 6 months of treatment, we compared the groups for complete ablation, defined as no uptake on a diagnostic I-131 scan, stimulated Tg level of <1.0 ng/mL, and Tg antibody level of <100 ng/mL. Ninety-five patients (72.0%) achieved complete ablation, with 57.1% (8/14), 78.2% (68/87), and 61.3% (19/31) in the 1,110 MBq, 3,700 MBq, and 5,550 MBq groups, respectively. There was no significant difference in the complete ablation rates between the three groups. In the multivariate analysis, the off-Tg level was a significant predictor of complete ablation. RAI therapy with low radioactivity (1,110 MBq) seemed sufficient for ablation in patients with papillary thyroid cancer with a pre-Tg level below 10 ng/mL. The off-Tg level is a promising and useful predictor of complete ablation after initial RAI therapy.
