The present study examined the reproductive factors and food intake pattern which influence on the breast cancer risk in Daegu${\cdot}$Gyungbuk area. The case subjects were 103 patients newly diagnosed as breast cancer at Kyungpook National University Hospital. The control subjects were 159 healthy women selected by frequency matching of age and menopausal status in the same community. The survey was conducted by individual interviews using questionnaires which include general and reproductive characteristics, dietary habits, and food frequency. The odds ratios were calculated by using unconditional logistic regression after adjusting for confounding variables. The mean age of the subjects was 50 yrs, and mean body mass index was significantly high in the patient group than in the control. The patient group had a significantly higher familial history of breast cancer and a significantly shorter breast-feeding period compared to the control group. It has been found no significant relationship between extrinsic hormone use such as oral contraceptives or estrogen replacement therapy and breast cancer risk. In regard of food habits, a high preference for the cooking method of steaming rather than frying, panbroiling or roasting was significantly associated with lower relative risk of breast cancer. The higher intake frequencies of fruits for all subjects, and seaweeds only for postmenopausal subjects were related with a significantly lower relative risk of breast cancer. The results of the study suggest that the possible risk factors for the breast cancer occurrence include high BMI, family history, less breast feeding experience, preference for the cooking method of frying, and less consumption of fruits and seaweeds. This study provides an useful data for nutrition education to prevent breast cancer for the residents in Daegu${\cdot}$Gyungbuk area.

Purpose: Estradiol in the menstrual cycle and ovulation induction as an important test of currently national nuclear medicine laboratory in the normal patients and patients with infertility tests are being performed. For the diagnosis of menopause is an important test with follicle stimulating hormone (FSH) and Luteinizing hormone (LH). Currently participating in external quality control of the nation's hospitals that is 54 percent of 37 hospitals, 20 hospitals have been using A's reagent. The kit's test results are highly different from other kit comes with the test results of specimens have been found. And for the phenomenon is to study the problem. Materials and Methods: Estraiol test were referred to our hospital which results of samples as more than 100pg/ml 75 specimens measured by radioimmunoassay(RIA) test with company A company B company C company D Kit, Chemiluminescent assay (CMIA) to examine and compare to the results from april to August in 2010. Results: Kit for each manufacturing company as measured by the results obtained using the average value of the correlation coefficient (R2) and A company 0.8906 B 0.9527 C 0.9547 and D company correlation coefficient of 0.873 showed a good correlation that measuring the results of A company high concentrations when Company B Company C Company D with CMIA test concentrations measured low results that the two cases were discovered specimens. Conclusion: Most of the test results of 75 samples came up with a similar trend, but two cases were reported in the patients very differently. A company result reported higher than 700 pg/ml, while the rest of other test results report was approximately 10 pg/ml. The common point of two samples more than 50 years patients are estimated to be diagnosed with cancer in postmenopausal patients receiving treatment and levels of FSH were found to be greater than 50 mIU/ml. Did not identify the exact cause. I suggest if you are using A company kit that need to again check when Estradiol result and follicle stimulating hormone results is higher.

In this research, we have analyzed the impact factors on the bone mineral density thru the examination of bone density difference in the entire femur, femoral neck and lumbar of adult women before the menopause in accordance with the general features, lifestyle, eating habits, health and body composition. The survey was conducted among adult women before the menopause and older than 30 years based on the data of the National Health and Nutrition Examination Survey carried out in the 4th term (2008-2009) and 5th term (2010-2011) and we would like to provide the research results for the establishment of recommendations or guidelines for the treatment of adult women before the menopause with regard to the impact factors on the bone mineral density and for the development of health education materials for the accurate measurement of bone mineral density of young women in order to prevent the postmenopausal osteoporosis. With respect to the general features of adult women before the menopause, the bone mineral density was higher in the entire femur at age 40-44, femoral neck at 35-39, in high-school education level, in the earlier menarche group, without smoking experiences, with regular walking time and exercise frequency and with the habits of eating no hamburger or pizza. With regard to the body composition, the bone mineral density was higher in obesity and lower in underweight cases, higher among people with abdominal obesity and weight control experiences. In terms of total body fat ratio, total amount of fat and muscle, the bone mineral density got gradually increased from the 1st quarter (Q1) to the 4th quarter(Q4). The obesity, disease, total amount of fat and muscle were shown to be significantly related with the bone mineral density in this research and it is required for young women to keep the adequate weight and the normal BMI in order to increase the bone mineral density. For the prevention of osteoporosis, it is advised to keep the right habits including regular exercise and no smoking discipline from the growing period and achieve the maximum bone mass thru the control of proper weight from a young age.

This study was performed to investigate the morphological and structural changes of bone tissues and the effects of irradiation on the mandibular bodies of rats which were fed low calcium diets. In order to carry out this experiment, 160 seven-week old Sprague-Dawley strain rats weighing about 150 gm were selected and equally divided into one normal diet group of 80 rats and one low calcium diet group with the remainder. These groups were then subdivided into two groups, 40 were assigned rats for each subdivided group, exposed to radiation. The Group 1 was composed of forty non-irradiated rats with normal diet, Group 2 of forty irradiated rats with normal diet, Group 3 forty non-irradiated rats with low calcium diet, and Group 4 forty irradiated rats with low calcium diet. The two irradiation groups received a single dose of 20 Gy on the jaw area only and irradiated with a cobalt-50 teletherapy unit. The rats with normal and low calcium diet groups were serially terminated by ten on the 3rd, the 7th, the 14th, and the 21st day after irradiation. After termination, both sides of the dead rats mandible were removed and fixed with 10% neutral formalin. The bone density of mandibular body was measured by use of bone mineral densitometer(Model DPX -alpha, Lunar Corp., U.SA). Triga Mark ill nuclear reactor in Korea Atomic Research Institute was used for neutron activation and then calcium contents of mandibular body were measured by using a 4096 multichannel analyzer (EG and G ORTEC 919 MCA, U.SA). Also the mandibular body was radiographed with a soft X-ray apparatus(Hitex Co., Ltd., Japan). Thereafter, the obtained microradiograms were observed by a light microscope and were used for the morphometric analysis using a image analyzer(Leco 2001 System, Leco Co., Canada). The morphometric analysis was performed for parameters such as the total area, the bone area, the inner and outer perimeters of the bone. The obtained results were as follows: 1. In the morphometric analysis, total area and outer perimeter of the mandibular bodies of Group 3 were a little smaller than that of Group 1. The mean bone width and bone area were much smaller than that of Group 1 and the inner perimeter of Group 3 was much longer than that of Group 1. The total area and outer perimeter of Group 2 and Group 4 showed little difference. The mean bone width and bone area of Group 4 were smaller than that of Group 2 and the inner perimeter of Group 4 was longer than that of Group 2. 2. The remarkable decreases of the number and thickness of trabeculae and also the resorption of endosteal surface of cortical bone could be seen in the microradiogram of Group 3, Group 4 since the 3rd day of experiment. On the 21st day of experiment, the above findings could be more clearly seen in Group 4 than in Group 3. 3. The bone mineral density of Group 3 was lesser than that of Group 1 and the bone mineral density of Group 4 was lesser than that of Group 2 on the 7th, 14th, 21st days. The irradiation caused the bone mineral density to be decreased regardless of diet. In the case of Groups with low calcium diet, the bone mineral density was much decreased on the 21st day than on the 3rd day of experiment. 4. The calcium content in mandible of Group 3 was smaller than that of Group 1 throughout the experiment. roup 4 showed the least amount of calcium content. The irradiation caused the calcium content to be decreased regardless of diet. In the case of Groups with low calcium diet, the calcium content was much decreased on the 21st day than on the 3rd day of experiment. In conclusion, the present study demonstrated that morphological changs and decrease of bone mass due to resorption of bone by low calcium diet, and that the resorption of bone could be found in the spongeous bone and endosteal surface of cortical bone. So the problem of resorption of bone must be considered when the old and the postmenopausal women are taken radiotherapy because the irradiation seems to be accelerated the resorption of osteoporotic bone.

Non-alcoholic fatty liver disease accompanies the rise in the prevalence of obesity, diabetes and the tendency toward high-fat dietary habits. Specifically, the higher prevalence of non-alcoholic fatty liver disease in men and postmenopausal women seems to be caused by the protective effects of estrogen against liver fibrosis, or lack thereof. There are no effective preventive therapies for liver diseases because the mechanisms underlying the progression of fatty liver diseases to chronic liver diseases and the protective effects of estrogen against fibrogenesis remain unclear. Recently, it has been reported that the hedgehog signaling pathway plays an important role in the progression of chronic liver diseases. Hedgehog, a morphogen regulating embryonic liver development, is expressed in injured livers but not in adult healthy livers. The level of hedgehog expression parallels the stages of liver diseases. Hedgehog induces myofibroblast activation and hepatic progenitor cell proliferation and leads to excessive liver fibrosis, whereas estrogen inhibits the activation of hepatic stellate cells to myofibroblasts and prevents liver fibrosis. Although the mechanism underlying the opposing actions of hedgehog and estrogen on liver fibrosis remain unclear, the suppressive effects of estrogen on the expression of osteopontin, a profibrogenic extracellular matrix protein and cytokine, and the inductive effects of hedgehog on osteopontin transcription suggest that estrogen and hedgehog are associated with liver fibrosis regulation. Therefore, further research on the estrogen-mediated regulatory mechanisms underlying the hedgehog-signaling pathway can identify the mechanism underlying liver fibrogenesis and contribute to developing therapies for preventing the progression of fibrosis to chronic liver diseases.

Survival data, prognostic factors, and patterns of failure were retrospectively analyzed for a total of 76 patients with adenocarcinoma of the uterine cervix treated between January 1981 and December 1987, which represents $4.1\%$ of all primary cervical carcinomas treated, at Department of Radiation Oncology, Yensei Cancer Center, Yonsei University College of Medicine. The mean age of the patients was 49 years (range, $27\~79$ years) and the peak incidence was in the group 50 to 59 years of age. More half of the patients were postmenopausal (46/76= $60.5\%$). Most patients ($76\%$) had abnormal vaginal bleeding either alone or in combination with other symptoms. The proportion of stage IIb was $43.4\%$. There were 4 major histologic subtypes: pure adenocarcinoma (48/76=$63.2\%$), adenosquamous carcinoma (20/76=$26.3\%$), papillary (5/76=$6.6\%$) and clear cell carcinoma (3/76=$3.9\%$). Of the many clinicopathologic variables evaluated for prognosis, the most significant prognostic factors were stage of disease and the size of tumor. The overall 5-year survival rate was $68\%$, and the 5-year survival rates for stage Ib, II and III were $90\%,\;66\%\;and\;54\%$, respectively. Control of pelvic tumors was achieved in $93.8\%,\;90.2\%\;and\;50.0\%$ of cases of stage Ib, II and III disease, respectively. In present study, treatment modalities (radiation therapy alone/combined operative and radiation therapy) did not affect the local control of tumor and the survival.

The phytochemical compounds of Pueraria, a medicinally important leguminous plant, include various isoflavones that have weak estrogenic activity and a potential role in preventing chronic disease, cancer, osteoporosis, and postmenopausal syndrome. However, the major isoflavones are derivatives of puerarin and occur mainly as unabsorbable and biologically inactive glycosides. The bioavailability of the glucosides can be increased by hydrolysis of the sugar moiety using ${\beta}$-glucosidase. In this study, we investigated the antioxidant effects of a Pueraria extract after fermentation by Lactobacillus rhamnosus BHN-LAB 76. The L. rhamnosus BHN-LAB 76 strain was inoculated into Pueraria powder and fermented at $37^{\circ}C$ for 72 hr. The total polyphenol content of the Pueraria extract increased by about 134% and the total flavonoid content increased around 110% after fermentation with L. rhamnosus BHN-LAB 76 when compared to a non-fermented Pueraria extract. Superoxide dismutase-like activities, DPPH radical scavenging, and ABTS radical scavenging increased by approximately 213%, 190%, and 107%, respectively, in the fermented Pueraria extract compared to the non-fermented Pueraria extract. Fermentation of Pueraria extracts with L. rhamnosus BHN-LAB 76 is therefore possible and can effectively increase the antioxidant effects. These results can be applied to the development of improved foods and cosmetic materials.

Purpose: The object of this study was to observe the anti-climacterium activity of Gagamguibiondam-tang (GGOT) on ovariectomized (OVX) rats, a well-documented rodent models resembles with women postmenopausal climacterium symptoms, as including cardiovascular diseases, obesity, hyperlipidemia, osteoporosis, organ steatosis and mental disorders. Methods: In this study, anti-climacteric effects were evaluated separated into three categories; 1) anti-obese, 2) anti-uterine atrophy and 3) anti-osteoporotic effects. Five groups were used (8 rats in each group); sham control, OVX control, GGOT 500, 250 and 125 mg/kg administered groups. Twenty-eight days after bilateral OVX surgery, GGOT were orally administered, once a day for 84 days, and then the changes on the body weight and gain during experimental periods, serum estradiol levels, abdominal fat pad and uterus weights with histopathology of abdominal fat pads (total thickness and mean adipocyte diameters) and uterus (total, epithelial and mucosal thickness, percentages of uterine gland regions) for anti-obese and estrogenic effects. In addition, femur, tibia and fourth or fifth lumbar vertebrae (L4 or L5) wet, dry and ash weights, mineral density (BMD), bone strength (failure load), serum osteocalcin and bone specific alkaline phosphatase (bALP) contents, histological and histomorphometrical analyses - bone mass and structure with bone resorption, were monitored for anti-osteoporosis activity. Results: As a result of OVX, noticeable increases of body weight and gains, food and water consumption, weights of abdominal fat pad deposited in dorsal abdominal cavity, serum osteocalcin levels were demonstrated in this experiment with decrease of uterus, femur, tibia and L5 weights, serum bALP and estradiol levels. In addition, marked hypertrophic changes of adipocytes located in deposited abdominal fat pads, uterine disused atrophic changes, decreases of bone mass and structures of femur, tibia and L4 were also observed in OVX control rats with dramatic increases of bone resorption markers, the Ocn and OS/BS at histopathological and histomorphometrical analysis in this study as compared with sham-operated control rats, suggesting the estrogen-deficient climacterium symptoms - obese and osteoporosis were induced by OVX, respectively. However, these estrogen-deficient climacterium symptoms induced by bilateral OVX in rats were significantly inhibited by 84 days of continuous oral treatment of GGOT 500, 250 and 125 mg/kg, respectively. Especially, GGOT 500, 250 and 125 mg/kg showed clear dose-dependent inhibitory activities on the OVX-induced climacterium signs. Conclusion: The results suggest that oral administration of GGOT 500, 250 and 125 mg/kg has clear dose-dependent favorable anti-climacterium effects - estrogenic, anti-obese and anti-osteoporotic activities in OVX rats in this experiment.
