Objectives: The epidemiological characteristics of breast cancer incidence by age group in Korean women are unique. This systematic review aimed to investigate the association between hormone replacement therapy (HRT) and breast cancer risk in Korean women. Methods: We searched electronic databases such as KoreaMed, KMbase, KISS, and RISS4U as well as PubMed for publications on Korean breast cancer patients. We also conducted manual searching based on references and citations in potential papers. All of the analytically epidemiologic studies that obtained individual data on HRT exposure and breast cancer occurrence in Korean women were selected. We restricted the inclusion of case-control studies to those that included age-matched controls. Estimates of summary odds ratio (SOR) with 95% confidence intervals (CIs) were calculated using random effect models. Results: One cohort and five case-control studies were finally selected. Based on the heterogeneity that existed among the six studies (I-squared=70.2%), a random effect model was applied. The summary effect size of HRT history from the six articles indicated no statistical significance in breast cancer risk (SOR, 0.983; 95% CI, 0.620 to 1.556). Conclusions: These facts support no significant effect of HRT history in the risk of breast cancer in Korean women. It is necessary to conduct a pooled analysis.

Purpose: To identify factors influencing women's intention to take hormone replacement therapy(HRT). Method: A cross-sectional survey design was utilized. A total of 116 married women aged 40 to 60 were recruited from women's groups in communities. They completed a structured questionnaire containing demographic characteristics, Orientation to Life Questionnaire, Menopausal Symptom Checklist, Health Belief of Korean Adult, Sexrole Idea of Kim, Dong-il, chronic illnesses, and a single item measuring marital satisfaction. Result: Thirteen percents of the women were currently taking HRT and 28.4% had intention to take HRT. Education, sense of coherence, and sex role attitude were related to women's susceptibility to menopause. Hysterectomy status and the level of sense of coherence explained women's perception of seriousness regarding menopause. In addition, chronic health conditions accounted for the variances of benefits and barriers to HRT. Factors influencing women's intention to take HRT were education, menopausal symptoms, and perceived benefits of HRT. Conclusion: Women's chronic health conditions, psychosocial characteristics as well as menopausal discomforts were associated with women's choice regarding HRT. Other factors related to decision making process of women's health seeking behaviors need to be explored.

Purpose: The purpose of this study was to examine the effects of Koryo Hand Therapy (KHT) on menopausal symptoms and hormone levels (Follicle Stimulating Hormone [FSH], Luteinizing Hormone [LH], and estradiol [$E_2$]) in climacteric women. Methods: The research design was a nonequivalent control group pretest-posttest design. Data were collected from November 28, 2005 to February 28, 2006. The 45 participants were assigned to either the experimental group (23) or control group (22). KHT was applied three times a week, for a total of 8 weeks to the women in the experimental group. Results: There was a statistically significant decrease in menopausal symptoms (F=42.49, p=.000), FSH level (F=26.98, p=.000) and LH level (F=5.31, p=.026) between the experimental and control groups. There was an increase of the estradiol level in the experimental group but the difference between the two groups was not statistically significant. Conclusion: KHT can be applied as a supportive nursing intervention to climacteric women. KHT is expected to be a complementary alternative intervention for health management of the climacteric women.

The purpose of this study was to investigate the effect of somatotype on the $VO_2max$ and hormone (adrenaline and noradrenaline) during treadmill walking. Forty healthy men participated and were randomized to four groups: Male 1 (M1) group, Male 2 (M2) group, Male 3 (M3) group, and Male 4 (M4) group. M4 group is the largest body type, and M1 group is the smaller the body type. Participants walked at a speed of 3.5 km/h for five minutes at an incline angle of $0^{\circ}$, $5^{\circ}$, and $10^{\circ}$ in the treadmill. Maximum oxygen consumption and hormone (adrenaline and noradrenaline) were measured. In the results, $VO_2max$ has significantly increased according to the degree of the treadmill inclination, and M4 group (larger body type) consumed more oxygen than the M1 group (smaller body type). In the hormone, there was a significant increase in adrenaline concentration after walking in all groups, and there was a significant difference in M1-M4, M2-M4 and M3-M4. The noradrenaline concentration significantly increased after treadmill gait in all groups, and there was no significant difference in noradrenaline between groups. This study suggests that the larger body type consumes more oxygen during walking, and treadmill walking contributes to an increase in the concentration of adrenaline and noradrenaline.

Globally, esophageal cancer is the seventh most common cancer, and the male-to-female ratio in esophageal adenocarcinoma (EAC) is significantly imbalanced at 4:1 to 8:1. Obesity, reflux, and smoking are known risk factors for this sex difference; however, fully explaining this remains challenging. Studies have investigated the link between exogenous sex hormones and esophageal cancer occurrence. A meta-analysis revealed a lower risk of EAC in female who had undergone hormone replacement therapy. Androgen-deprivation therapy in patients with prostate cancer was associated with a decreased risk of EAC. Tissue-based studies have reported varied results regarding the relationship between estrogen receptor expression and survival in female patients with esophageal squamous cell carcinoma (ESCC). Circulating hormone studies have suggested that higher testosterone and luteinizing hormone levels decreased EAC risk in men, and free testosterone was inversely correlated in female with ESCC. However, a high androgen-estrogen ratio in male patients with EAC was linked to increased odds of EAC. Sex hormones influence carcinogenesis, affecting cell proliferation, differentiation, metabolism, inflammation, and cell death. The studies were limited by the small sample size and varying hormone measurement methods; thus, future studies with definitive conclusions on the association between esophageal cancer and sex hormones are warranted.

Menopausal women experience urogenitory and vasomotor symptoms with increased risk of osteoporosis and cardiovascular diseases, which can be reduced by hormone replacement therapy. However unopposed estrogen therapy has been associated with an increased risk of endometrial hypeiplasia or cancer. The objectives of this study were to compare effects of continuous vs. sequential hormone replacement therapy (HRT) on lipid profile, bone mineral density and menopausal symptoms of postmenopausal women and to assess how they perceive the menopause and HRT culturally. In this retrospective study, women in menopause longer than 6 months, normal in the mam-mogram and Papanicolaou smear, cholesterol level lower than 190 mg/dL or triglyceride level lower 4han 500 mg/dL were treated with Srogen (conjugated equine estrogen 0.625 mg tablet) and Provera (medroxyprogesterone acetate 2.5 mg tablet) for continuous treatment(CT) or Cycloprogynova (Estradiol valerate 2 mg and Norgestrel 0.5 mg complex tablet) for sequential treatment(ST). They were evaluated for lipid profile, bone mineral density, menopausal symptoms, side effects and their perception of menopause and HRT. As results, total sixty-seven patients out of ninety-four enrollees were included in final analysis (33 in continuous therapy, 34 in sequential therapy). There were significant decrease in total cholesterol ($15.04\pm3.17$, p=0.0001), LDL ($19.72\pm3.27$, p=0.0001), and increase in HDL ($5.89\pm1.63$, p=0.0001). Bone minora) density increased significantly with HRT ($0.02\pm0.11$, p=0.0001). But, there were no significant differences in change of lipid profile between continuous and sequential therapy: Total cholesterol, $13.12\pm4.7\;vs.\;16.91\pm4.3;\;LDL\;20.53\pm4.1\;vs.\;18.93\pm5.12:HDL\;7.15\pm2.3\;vs.\;4.67\pm2.2,\;p>0.05$. Incidences of flush reduced from $75\%\;(CT)\;to\;3.13\%\;and\;71.88\%\;(ST)\;to\;9.35\%$. The change of endometrium and breast were found 3 (CT) and 5 (ST) women, respectively. Most of women recognized that HRT is necessary $(70\%)$ for postmenopausal period but did not understand well the cardiovascular protective effect. In conclusion, hormone replacement therapy was effective in improving lipid profile, bone mineral density and menopausal symptoms in both continuous and sequential treatments with similar efficacy.

The purpose of this study is to investigate the effects of thyroid hormone on the left ventricular(LV) volume arid function in man with untreated hyperthyroidism and to determine the effects of successful therapy for thyrotoxicosis on the ventricular pathophysiology. In the present study, equilibrium radionuclide cardiac angiography was performed and LV volume index, ejection phase indexes of LV performance, serum thyroid hormone levels and other hemodynamic parameters were measured in 28 normal subjects and 39 patients with hyperthyroidism before treatment and again every 4 weeks for the first 2 months after the initiation of effective therapy. The results obtained were as follows; 1) In the untreated hyperthyroid state heart rate, blood volume, cardiac index and stroke volume index($97{\pm}14$ beats/min, $73.5{\pm}11.8ml/kg,\;6.9{\pm}1.4\;l/min/m^2$ and $77.6{\pm}13.8ml/m^2$, respectively) were increased significantly compared to those in normal control($74{\pm}12beats/min$, $66.6{\pm}14.8ml/kg,\;3.8{\pm}1.2\;l/min/m^2$ and $56.6{\pm}13.2ml/m^2$ respectively). $(Mean{\pm}SD)$ 2) There was a significant increase in LV end-diastolic volume index in patients with hyperthyroidism ($30.5{\pm}7.5$ for hyperthyroid group compared to a normal control of $22.2{\pm}6.5$; p<0.001), whereas end-systolic volume index remained unchanged $9.6{\pm}3.6\;and\;8.8{\pm}3.3$ respectively).3) In patients with hyperthyroidism, LV ejection fraction was $70.0{\pm}5.6%$, fractional shortening $32.9{\pm}5.1%$, mean velocity of circumferential fiber shortening(mean Vcf) $1.34{\pm}0.31$ circ/sec and maximum ejection rate $3.47{\pm}0.80$. All the ejection phase indexes were significantly greater than those in normal control($65.2{\pm}5.7%,\;28.8{\pm}3.2%,\;0.88{\pm}0.37$ circ/see and $2.27{\pm}0.50$, respectively; p<0.001). 4) Effective therapy produced significant decrease in all the values of serum thyroid hormone concentrations(p<0.00l), hemodynamic parameters(p<0.001), end-diastolic volume index(p<0.01) and ejection phase indexes of LV contractility in patients with hyperthyroidism and after one to two months, when the patients were euthyroid, these measurements were in the range of normal. 5) A significant linear correlation between mean Vcf and serum thyroxine level(r=0.63, p<0.001) as well as between mean Vcf and serum triiodothyronine level(r=0.62, p<0.001) was found. The lesser degree of correlation was also noted between other ejection phase indexes and serum thyroid hormone concentrations. The results indicate that the major effects of excess thyroid hormone on the LV in human beings with hyperthyroidism are an enhancement of LV function and an increase in LV enddiastolic volume and that these effects cause predictable reversible cardiac alteration which are changed dramatically and immediately after effective therapy.

Objectives: After the discontinuance of the Women's Health Initiative (WHI)clinical trial in the U.S. in July 2002, I thought that the domestic medical field would come to a crisis in hormonal treatment for perimenopausal and postmenopausal women. However, the domestic condition of HRT has barely changed. This study was designed to investigate world research trends in HRT and bring forward the response of the Traditional Korean Medicine (TKM) Research Group. Methods: I investigated recent domestic ;md world research trends about HRT and climacteric syndrome. Based on this analysis, I predicted western medical research trends and direction for HRT and medical care of perimenopausal and postmenopausal women. Results and Conclusions: I propose that we (TKM Research Group) have to explain the side effects of HRT for postmenopausal women and try to suggest complementary therapy for it. For that aim, the Association of Korean Medicine's effort is very important, as well as personal practitioner's actions.
