Isoflavones are naturally occurring plant chemicals belonging to the 'phytoestrogen' class. The isoflavones are strikingly similar in chemical structure to natural estrogens. The phenolic ring is a key structural element of most compounds that bind to estrogen receptors. Dietary components that recently have received attention for their action as phytoestrogens are soy isoflavones. Soy products are the most significant dietary sources of isoflavones. Recently It is concerned clinical nutrition of isoflavone that is driven by reason of alternative sources of exogenous estrogen are constantly being needed. Estrogen therapy after the menopause offers protection from cardiovascular disease, reduces the extent of osteoporosis and relieves menopausal symptoms. Exogenous estrogen treatment is a fear of possible increased risk of developing breast cancer and because of side effects. Daily intake of soybean or soy food can affirmative effect to disease occurrence, that is based on mechanical investigation, experimental results of animals and human. Research into isoflavone is going on various field to relieve hormone - dependent disease such as cancer, menopausal symptom, cardiovascular disease and osteoporosis. Isoflavone is plenty in soybean meal, soy by-product, but only limited information is available on isoflavone efficacy into animal husbandry. Thus we conducted three experiments to investigate the effects of dietary isoflavone on productivities, antioxidative responses and bone metabolism in poultry. Dietary supplementation of isoflavone resulted in preventing the lipid oxidation of plasma and egg yolk. Dietary isoflavone improved bone development in egg-type growing chicks and broilers in terms of tibial strength. It was suggested that the proper use of feed additives such as isoflavone might provide means of improving antioxidative effect, skeletal strength, egg and eggshell quality.
In the atherosclerotic subjects, arterial endothelial cell injury and plaque formation are suspected to be strong causable factors in developing acute coronary syndrome, and it was revealed that platelets have a very important role in this case. Women are exposed to atherosclerosis at a different degree after menopause or oral contraception. The purpose of this study was to determine the effects of endogenous and exogenous estrogen on the degree of platelet aggregation in platelet rich plasma(PRP) in twenty nonsmoking healthy Korean women for 12 weeks. The subjects were assigned to three groups: (1) eight women aged 49 to 60(yr) for the postmenopausel(Pst) group, (2) eight, aged 22 to 30(yr) for the premenopausa(Pre) group, (3) four, aged 23 to 30(yr) for the oral contraceptive (OC) group which used triphasic OC formulation. Fasting blood sample were obtained from the subjects, (1) once per 6 weeks in the Pst group, (2) every phase of the menstrual cycle in the Pre group, (3) each once during and after OC administration in the OC group. ADP, collagen and epinephrine were used as aggregating reagents, and platelet aggregation and time(Δt: time reaching to the maximum point of aggregation) in PRP were measured at the maximum point of aggregation in five minutes. All the data were adjusted for dietary effects, personality type and body mass index(BMI) by using analysis of covariation(ANCOVA). Platelet aggregation to ADP and collagen(MADP and MCOLL) were not significantly different among the three groups, and Δt to ADP and collagen(TADP and TCOLL) were not either. But maximum platelet aggregability and Δt to epinephrine(MEPIN and TEPIN) were significantly different among the three groups, and the OC group showed the lowest value (p<0.01). Maxtimum platelet aggregability and Δt during the menstrual cycle were not significantly different in the Pre group. Any other significant differences in the maximum platelet aggregability and Δt were found between oral contraception phase and washing out phase(menstruation) in the OC group. In results, maximum platelet aggregability and aggregation time to ADP and collagen seemed not to be affected by endogenous and exogenous estrogen, even though MEPIN and TEPIN showed significantly low in the OC group among the three groups.
Background: Pattern identification is a unique diagnostic method of traditional Oriental medicine that has recently been the target of questionnaire-based research. Sasang (four-types) constitutional medicine (SCM) is a practice in traditional Korean medicine that seeks to promote objectivity in diagnostics. This paper attempts to illuminate the relationship between constitutions and the pathogenic factors of pattern identification through questionnaires completed by menopausal women about their symptoms. Methods: From March to October 2012, we examined 291 women from the general population, with ages ranging from 40 to 60 years, applying the Kupperman index, the Menopause-Specific Quality of Life Questionnaire (MENQOL), pattern identification based on the Diagnosis System of Oriental Medicine (DSOM), and SCM. We then analyzed the relationship between constitutional type and pathogenic factors. Results: No significant differences were found in the scores of either the Kupperman index or MENQOL questionnaire in relation to constitutional type. However, in a statistical analysis correlating the DSOM pathogenic factor scores (PFS) with the scores of the Kupperman index and MENQOL vasomotor subscale, heat showed a significant positive correlation with SoYang type (SY) and TaeEum type (TE), but not SoEum type (SE), while insufficiency of yin and insufficiency of yang, as well as blood deficiency, showed a significant positive correlation with the TE and SE types. Conclusion: The pathogenic factors in the menopausal symptoms of middle-aged women, specifically the prominent menopausal symptom of facial flushing, differed significantly according to constitutional type.
Purpose: This study was conducted to identify factors related to osteoporosis prevalence in postmenopausal women. Methods: This study was a secondary analysis research using data from the Eighth Korea National Health and Nutrition Examination Survey (KNHANES VIII-1), 2019, which were downloaded from the KNHANES website. The subjects of this study were 1,791 postmenopausal women who participated in the KNHANES VIII-1, 2019. Data analysis was performed using the IBM SPSS 21.0 program and complex sample design analysis was performed considering factors such as weight, cluster, and strata. Results: Osteoporosis prevalence of in postmenopausal women was 17.5%. Factors related to osteoporosis prevalence were age (65~74 years old, ≥75 years old), house income (low), household type (one-person household), postmenopausal period (10~19 years), drinking (non-drinking). Conclusion: Interventions for osteoporosis prevention and management in postmenopausal women need to focus on women less than 10 years after menopause and one-person household women. Furthermore, it is necessary to expand bone density testing for the early detection of osteoporosis in postmenopausal women.

Purpose: To investigate the prognostic factors and effectiveness of postoperative radiotherapy alone for endometrial carcinoma. Materials and Methods: Sixty four patients with stage I-III endometrial cancer (EC) treated with postoperative radiotherapy alone between January 1989 and December 2008 at the Keimyung University Dongsan Medical Center were chosen for the present study. Typically, total hysterectomy, salpingo-oophorectomy and lymphadenectomy were performed on the patient's pelvis. Total dose from 50.4 Gy to 63 Gy was irradiated at pelvis or extended field. Thirteen patients were treated with Co-60 or Ir-192 intracavitary radiotherapy. Follow-up periods were from 7 to 270 months, with a median of 56 months. Results: Five year overall survival (OS) rate was 58.7%, respectively. Five year disease-free survival (DFS) rate was 59.2%, respectively. In univariate analysis for OS and DFS, stage, menopausal age, type of operation, serosal invasion, and lymph node involvement were found to be statistically significant. Histologic type was marginally significant. In multivariate analysis for OS and DFS, stage, types of operation, histologic type were also found to be statistically significant. Treatment failure occurred in 14 patients. The main pattern of failure was found to be distant metastasis. Time to distant metastasis was from 3 to 86 months (median, 12 months). There were no grade 3 or 4 complications. Conclusion: Stage, types of operation, and histologic type could be the predictive prognostic factors in patients. We contemplated postoperative radiation as effective and safe treatment method for EC. Additional treatment would be needed to reduce distant metastasis.
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).

As part of our current work to discover structurally and/or biologically novel compounds from Korean wild mushrooms, we isolated five ergostane-type steroids (1-5) from the fruiting bodies of Xerula furfuracea via repeated column chromatographic separations and HPLC purification. The chemical structures of the isolated steroids were shown to be (22E,24R)-24-methylcholesta-4,22-diene-3,6-dione (1), ergosta-7,22-diene-3β,5α,6β-triol (2), ergosta-7,22-diene-3β,5α,6β,9α-tetraol (3), (22E,24R)-5α,8α-epidioxyergosta-6,22-diene-3β-ol-3-O-β-D-glucopyranoside (4), and (22E,24R)-5α,8α-epidioxyergosta-6,9,22-triene-3β-ol-3-O-β-D-glucopyranoside (5)based on comparison of the data regarding their spectroscopic and physical properties with those of previous studies. Notably, this is the first report on the presence of the identified steroids (1-5) in this mushroom. We tested compounds 1-5 to determine their effects on adipogenesis and osteogenesis in the mouse mesenchymal stem cell line C3H10T1/2 and found that compounds 4 and 5 suppressed the differentiation of stem cells into adipocytes. Notably, in addition to its suppressive effect on adipogenesis, compound 5 was also shown to promote the osteogenic differentiation of stem cells. These findings demonstrate that the bioactive compounds isolated might be effective for the treatment of menopause-associated syndromes, such as osteoporosis and obesity, as the isolated compounds were shown to suppress adipogenesis and/or promote osteogenesis of stem cells.
Purpose: The purpose of this study is to identify the factors that influence HRQOL for married working women. Methods: The subjects of the study were 577 full-time working married women living in five province. The data were collected using a structured questionnaire, from April to September 2006. Results: As for the general characteristics, there was a statistically significant difference in the level of HRQOL(total) according to age, education, menopause, family income, leisure activities, residence, duration of marriage, number of children, firstborn age, household duties of husband, job, career, type of work, women's income, and purpose of working. The level of HRQOL showed a statistically significant difference according to BMI and behavioral factors except for caffeine intake and follow up health screening. The HRQOL were significantly correlated with depression, marital satisfaction and job satisfaction. The multiple regression analysis showed that the HRQOL were significantly predicted by depression, marital satisfaction, education, regular exercise, daily working hours and job satisfaction. These variables explained 48.5% of the variance of HRQOL. Depression was the main predictor of HRQOL. Conclusion: It could be concluded that nursing intervention to reduce depression should be developed to promote the HRQOL for married working women.
The purpose of this study was to analyze consumption patterns of health functional foods (HFF) according to climacteric symptoms. Subjects were 450 middle-aged women divided into four groups by Kupperman's index. This study collected all information by self-administrated questionnaires. Higher Kupperman's index was associated with higher Menopause-specific quality of life questionnaire (MENQOL) (P<0.001) and current smoker ratio (P<0.01) as well as lower monthly income (P<0.05). Exactly 28.4% of subjects showed negative responses to effectiveness of HFF. The average number of HFF intake per person was 2.01. The main reason for consumption of HFF was treatment or prevention of disease (33.6%). The information source for buying HFF was family or relatives (40.0%). The main types of HFF were vitamins (28.2%), omega-3 fatty acid (18.6%) and red ginseng (17.3%). The intake ratio of individual approval type (Cynanchum extract and Angeli extract) was significantly higher in subjects with high Kupperman's index (P<0.001). In conclusion, these results can be used as basic data that reflect middle-aged women's needs for HFF intake according to climacteric symptoms.
Purpose: This study was conducted to ascertain the effectiveness of forest healing therapy by analyzing researches on forest healing therapy applied to Korean adults and to confirm that forest healing therapy can be used as a therapeutic intervention program for elderly nursing or rehabilitation nursing. Methods: We searched 972 research papers on forest therapy applied to Korean adults. We reviewed appropriate 25 research papers with experimental design among them in the final analysis. Results: Forest healing therapy had physiological and psychosocial effects. First of all, it showed physiological effects to reduce stress index such as heart rate variation. Forest therapy also improved melatonin level in blood of middle-aged women with menopause and increased alpha wave in electroencephalogram and decreased lipid level and superoxide dismutase in blood. Second, forest healing therapy showed psychosocial effects to reduce depression and to improve mental health. But the effects appeared differently depending on the implementing type, period of forest healing therapy, and the professionalism of therapists. Therefore, if forest healing therapy would be applied to nursing, it should be based on its key principle, in other words, its principle of action-interaction-response of forest healing therapy. Conclusion: The results of this study could be used to develop a forest healing program as an intervention of nursing.
