In order to develop samultang with reduced side effects, modified samultang using omija was oral administered to rats with ovarian resection, and changes in evaluation indicators of functional efficacy in women's menopause were measured. In weight gain, relative weight of uterus and vagina, blood lipid-related indicators, and changes in blood estradiol, there was no statistically significant improvement effect in modified Samultang compared to the control group. However, the expression of estrogen receptor alpha and beta in intrauterine tissue tended to increase, and the expression of phosphorylated ERK, which is known to be involved in estrogen receptor signaling, showed a significant increase in activation in ERK and AKT. The expression amount of phosphorylation AKT was not significant, but showed an increasing tendency. Even though the test substance was administered in a relatively small dose, it is judged that the test substance modified Samultang has the ability to activate estrogen receptor. In the future, it is expected that it can be used as a useful natural mixture to show the efficacy of samultang with fewer gastrointestinal disorders.

Since the first radioimmunoassay (RIA) was developed in 1970s, many conventional RIAs and non-isotopic immunoassays (NIA) had been developed in which the degree of precision, accuracy, specificity and practicability have progressively increased. Recently ultrasensitive assay method at femtogram to determine testosterone in serum, saliva and feces is required for the study of sexual dysfunctions in male and female, monitoring the psychological stress and conditions, aging process such as menopause and partial androgen deficiency in aging male, the hormonal changes of small experimental animals etc. This review discussed the recentd evelopments of steroid assay methods, based upon the testosterone assay results of authors far 20 years, and the problems associated the assay set-up, the characterizations and applications of the established procedures, and desifls of assay, reliablity criteria, and the practical aspects of assay set-up and application, based upon the data of the authors. The present study demonstrates the general problems methods to be consider in order to set up the highly sensitive assay methods and to increase the assay quality and the necessity of assay quality control program. To improve the assay quality of each laboratory and to compare the assay results in homeland, the national QC programs should be organized.

To monitor the reproductive patterns of endangered common chimpanzee including annual reproductive cycle, amenorrhea, breeding season, and pregnancy diagnosis, Time-Resolved Fluorescence Immuno Assay (TR-FIA) was used to trace MRH (estradiol, progesterone, testosterone) and human chorionic gonadotropin (HCG). In result of this research, age was not the important factor in determining the reproduction capability in common chimpanzee; it was rather greatly influenced by the combination of various factors such as individual's fertilizing ability, presence of obstetrical diseases, the pattern of mating behavior, and the mental communication under the introduction of a mating partner. This research will play an important role in operating conservation project for common chimpanzees and can be extended also for shedding new light on understanding human menopause and obstetrical diseases.

Women have a greater incidence of coronary heart disease (CHD) after menopause. This relates to hormone imbalance-induced changes in known CHD risk factors, especially hyperlipidemia. The purpose of this study was to explore d1e differences in food consumption and food sources of nutrients in the Korean diet between postmenopausal women aged 50-74 years with normocholesterolemia(NC) and those with hypercholesterolemia(HC). Each subject was either classified as part of the NC group (n=39, serum total cholesterol con. ＜200 mg/$dl$) or the HC group (n=31, serum total cholesterol con. $\geq$240 mg/dl) based on the Guideline for Korean Hyperlipidemia.l Diet was assessed through a validated semi-quantitative food frequency questionnaire. Consumption of foods such as biscuits and/or crackers, squid and eggs was significantly (p＜0.05) higher in the HC group than in the NC group. On the other hand, consumption of potatoes/starches and carrots was significantly (p＜0.05) lower in the HC group than in the NC group. There was no significant difference between the two groups in terms of the consumption of legumes and legume products containing phytoestrogen and we could not find a relationship between legumes and legume products and serum cholesterol levels. Consumption of green tea tended to be lower in the HC group than in the NC group. Major sources of cholesterol, cholesterol-saturated index and vitamin A in the diets of the HC group consisted of foods high in cholesterol. Our results confirm that postmenopausal women with hypercholesterolemia in Korea tend to consume cholesterol-rich foods and dishes.

Purpose: Natural menopause resulting in the decline in endogenous estrogen concentrations is responsible for an increased risk of coronary heart disease in postmenopausal women. The purpose of the study was to examine the effects of a 6-month Tai Chi exercise program on cardiovascular risk factors and quality of life in post-menopausal women. Methods: A quasi-experimental design with pretest and posttest measures was used. The participants in the study, 29 women in the Tai Chi group and 31 in the control group, were enrolled for 6 months. Results: After 6 months of Tai Chi exercise, total cholesterol (M=213 to 185), LDL-cholesterol (M=135 to 128), and their 10 yr cardiovascular disease risk (M=2.62 to 2.27) had improved significantly for the Tai Chi participants compared to the control group. Total scores for quality of life along with the sub-dimensions of health perception and mental functioning were also significantly higher in the Tai Chi participants. Conclusion: Tai Chi exercise favorably affected cardiovascular health and quality of life in post-menopausal women after 6 months. Additional rigorous studies are needed to examine long term effects on the prevention of cardiovascular disease in this population.

Objectives: The aim of this study is to find out the effects of dance movement therapy(DMT) on anxiety, depression, and life quality by applying DMT program to climacteric women. Methods: The subjects of the research are climacteric women between the ages of 45 and 55 who located in the city of oo in Chollabukdo. The program was conducted with the subjects of a total of 27 women less than one year after menopause, 14 in the experiment group and 13 in the comparison group, 90 minutes a session, once a week, for 15 weeks. Results: The results show that the points of anxiety and depression decreased significantly in the experiment group which participated in the DMT program (p<0.05). The points of life increased significantly in physical & mental wellbeing, competence, and stability (p<0.05). Vitality points increased, but not significantly. Conclusions: This means that DMT decreases anxiety and depression of climacteric women, has positive effects on life quality related to health, and can help increase physical, mental, and emotional wellbeing of climacteric women.

Although there is a growing interest in male menopause, a phenomenon associated with male hormone depletion, current kits using antibodies to quantify male hormones are expensive. In this study, we constructed an in vitro system for verifying the activity or concentration of male steroid hormones using a transcriptional activity test. A reporter plasmid, pGL2-Neo-ARE-AdE1BTATA, which reacts to testosterone, was constructed. In this plasmid, the ARE-AdE1bTATA sequences can be bounded by the testosterone - androgen receptor complex to express luciferase as a reporter. Then, a stable transfection was performed on the human prostate cancer cell line, LNcap-LN3. The constructed LNcap-LN3/pGL2-Neo-ARE-AdE1BTATA testosterone compound detection (TCD) system showed quantitatively proportional luciferase activities to concentrations of $10^{-13}$ to $10^{-8}M$ of standard testosterone. The established in vitro TCD system will contribute to the development of materials for health/functional foods and drugs as it will be possible to search en masse for testosterone-like or testosterone-inhibiting substances derived from natural materials.

Trigonella foenum-graceum L. (fenugreek) is a phytoestrogen, a nonsteroidal organic chemical compound from plants which has similar mechanism of action to sex hormone estradiol-$17{\beta}$. This study aims to assess the effectivity of fenugreek seeds extract on collagen type I alpha 1 (COL1A1) and collagen type III alpha 1 (COL3A1) which are both decreased in aging skin and become worsen after menopause. This in vitro experimental study used old human dermal fibroblast from leftover tissue of blepharoplasty on a postmenopausal woman (old HDF). As a control of the fenugreek's ability to trigger collagen production, we used fibroblast from preputium (young HDF). Subsequent to fibroblast isolation and culture, toxicity test was conducted on both old and young HDF by measuring cell viability on fenugreek extract with the concentration of 5 mg/mL to $1.2{\mu}g/mL$ which will be tested on both HDF to examine COL1A1 and COL3A1 using ELISA, compared to no treatment and 5 nM estradiol. Old HDF showed a 4 times slower proliferation compared to young HDF (p<0.05). Toxicity test revealed fenugreek concentration of $0.5-2{\mu}g/mL$ was non-toxic to both old and young HDF. The most significant fenugreek concentration to increase COL1A1 and COL3A1 secretion was $2{\mu}g/mL$ (p<0.05).

To determine the relationships between soybean food intake, dietary isoflavone intake, and osteoporosis incidence, questionnaire surveys, bone mineral density measurements, and dietary surveys by food record were performed with 19 postmenopausal women ($57.6{\pm}7.3$ yrs of age) in Daejeon city. The subjects were divided into two groups: an 'osteoporosis group' (OG, n=10) and a 'normal group' (NG, n=9). Mean age, height, and body weight were similar between the two groups but BMI was higher in OG than in NG. Mean age at menarche was not different between the two groups. However, mean number of childbirths was greater in OG than in NG and mean total period of lactation was shorter in OG. Mean exercise time per week was similar between the two groups, and mean time of sunlight exposure tended to be shorter in OG. Mean daily intake of calcium was lower in OG whereas sodium intake was higher in OG. Mean daily intakes of total soybean food (OG: $203.8{\pm}84.6\;g/d$, NG: $285.0{\pm}146.3\;g/d$) and total dietary isoflavone (OG: $29.1{\pm}14.3\;mg/d$, NG: $38.3{\pm}23.1\;mg/d$) were not different between the two groups. However, greater intakes of soybean food and dietary isoflavone were associated with higher bone mineral density, respectively. The above results indicate that osteoporosis incidence tends to be influenced by BMI, maternal factors, dietary nutrient intakes, soybean food intakes, and dietary isoflavone intakes in postmenopausal women; although no significant differences in soybean food and dietary isoflavone intake were found between the two groups. This tendency implies that greater intakes of soybean food and dietary isoflavone lead to lower incidence of osteoporosis in postmenopausal women.
