Purpose: The purpose of this study was to investigate the degree of the gender role identity and quality of life of women applying hormone replacement therapy with hysterectomy and to identify the relation among these variables. Methods: The subjects were 121 outpatients applying hormone replacement therapy with hysterectomy at a university hospital in Busan province. The data were collected using self-reported questionnaire and medical record, from September to October 2008. Results: There were statistically significant differences in the degree of quality of life according to the age, educational level, occupation, family economic status, Body Mass Index (BMI), menopause state, duration to restarting intercourse from hysterectomy, discomfort from intercourse, satisfaction from intercourse and duration, sources, and formulation of hormone replacement therapy (HRT). The femininity identity group occupied the largest proportion (31.4%), and then the masculinity identity group (28.1%), the undifferentiated identity group (26.4%), and finally the androgyny identity group (14.1%). There was a positive correlation between femininity and quality of life (r=.276, p=.002). Conclusion: These results indicate that HRT helps the women's sense of loss caused by hysterectomy to be reduced, the postmenopausal symptom after hysterectomy to be relieved and the quality of life to be improved.

Purpose: This study aimed to identify factors influencing quality of life in post-menopausal women. Methods: The participants were 194 post-menopausal women who visited a women's clinic in Changwon, Korea from July 1 to August 31, 2018, and completed questionnaires containing items on menopausal symptoms, marital intimacy, current menopausal hormone therapy (MHT), and quality of life. Collected data were analyzed by descriptive statistics, the independent t-test, Pearson correlation coefficients, and multiple regression using SPSS for Windows version 23.0. Results: Quality of life had a significant negative correlation with menopausal symptoms (r=-.40, p<.001), and a significant positive correlation with marital intimacy (r=.54, p<.001). The factors influencing the quality of life of post-menopausal women were current MHT (t=6.32, p<.001), marital intimacy (t=4.94, p<.001), monthly family income (t=4.78, p<.001), menopausal symptoms (t=-4.37, p<.001), and education level (t=3.66, p<.001). These variables had an explanatory power of 59.2% for quality of life in post-menopausal women. Conclusion: In order to improve the quality of life of post-menopausal women, nursing interventions are needed to help menopausal women choose appropriate MHT, alleviate menopausal symptoms, and increase marital intimacy. Interventions should also be prioritized for women of a low educational level and with a low income in consideration of their health problems.

Objective: To investigate assisted reproductive technology (ART) outcomes in women with WHO class I anovulation compared with control group. Design: Retrospective case-control study. Methods: Twenty-three infertile women with hypogonadotropic hypogonadism (H-H) who undertook ART procedure from August 2003 to January 2009 were enrolled in this study. A total of 59 cycles (H-H group) were included; Intra-uterine insemination with super-ovulation (SO-IUI, 32 cycles), in vitro fertilization with fresh embryo transfer (IVF-ET, 18 cycles) and subsequent frozenthawed embryo transfer (FET, 9 cycles). Age and BMI matched 146 cycles of infertile women were collected as control group; 64 cycles of unexplained infertile women for SO-IUI and 54 cycles of IVF-ET and 28 cycles of FET with tubal factor. We compared ART and pregnancy outcomes such as clinical pregnancy rate (CPR), clinical abortion rate (CAR), and live birth rate (LBR) between the two groups. Results: There was no difference in the mean age ($32.7{\pm}3.3$ vs. $32.6{\pm}2.7$ yrs) and BMI ($21.0{\pm}3.1$ vs. $20.8{\pm}3.1kg/m^2$) between two groups. Mean levels of basal LH, FSH, and $E_2$ in H-H group were $0.62{\pm}0.35$ mIU/ml, $2.60{\pm}2.30$ mIU/ml and $10.1{\pm}8.2$ pg/ml, respectively. For ovarian stimulation, H-H group needed higher total amount of gonadotropin injected and longer duration for ovarian stimulation (p<0.001). In SO-IUI cycles, there was no significant difference of CPR, CAR, and LBR between the two groups. In IVF-ET treatment, H-H group presented higher mean $E_2$ level on hCG day ($3104.8{\pm}1020.2$ pg/ml vs. $1878.3{\pm}1197.7$ pg/ml, p<0.001) with lower CPR (16.7 vs. 37.0%, p=0.11) and LBR (5.6 vs. 33.3%, p=0.02) and higher CAR (66.7 vs. 10.0%, p=0.02) compared with the control group. However, subsequent FET cycles showed no significant difference of CPR, CAR, and LBR between the two groups. Conclusion: H-H patients need higher dosage of gonadotropin and longer duration for ovarian stimulation compared with the control groups. Significantly poor pregnancy outcomes in IVF-ET cycles of H-H group may be due to detrimental endometrial factors caused by higher $E_2$ level and the absence of previous hormonal exposure on endometrium.

The present study aimed to evaluate the effect of Dendropanax morbifera (DM) extract on postmenopausal syndrome and to develop DM extract as an alternative for hormonal therapy. The following seven groups of rats; normal control (sham), ovariectomized (OVX) control, Punica granatum (PG)-treated group (770 mg/kg), estradiol treated group (0.5 mg/kg), and three DM-treated groups (200, 500, 1000 mg/kg) were compared. Indicated compounds were administrated once a day for eight weeks. To evaluate the estrogenic effect of DM extract, western blot analysis was performed on the liver tissue to confirm the expression of estrogen receptor ($ER-{\alpha}$, $ER-{\beta}$). Our analysis showed that after DM administration, collagen cross-linked C-telopeptide (CTX) value decreased while $ER-{\alpha}$ protein expression increased in a dose-dependent manner through the MAPK/ERK pathway in OVX rats. These results suggest that Dendropanax morbifera exerts estrogenic effect by inducing estrogen receptor expression and activating MAPK/ERK pathway.

Women who undergo natural menopause transition have increased numbers of risk factors relating to metabolic syndrome due to estrogen deficiency. This study was conducted to investigate the effect of Superhongmi bran extract on metabolic syndrome improvement in menopausal women. Thirty women, who participated in a randomized, double-blind, placebo-controlled trial, were assigned to placebo-control (n=15) or Superhongmi bran extract (n=15) groups and were asked to consume two tablets (350 mg per extract per tablet) per day. After 12 weeks, weight, body mass index (BMI), plasma triglyceride (TG) levels, and total cholesterol (TC) levels were significantly decreased, whereas HDL-cholesterol (HDL-C), apolipoprotein A1 (ApoA1), adiponectin, superoxide dismutase 1 (SOD1), and GSH (glutathione) concentrations were significantly increased in the Superhongmi bran extract group. Moreover, $17{\beta}-estradiol$, and progesterone levels in the Superhongmi group were significantly higher than those in the placebo-control group. These results suggest that Superhongmi bran extract alleviates metabolic symptom in menopausal women.

Biomechanical reactions of tooth movement are the combination of bone formation and resorption, in which many paracrine factors are involved. The sex hormone is one of the paracrine factors and the sex hormonal level of an adult female vanes according to the body condition, e.g. mensturation, pregnancy, postmenopause, etc. Although the exact mechanism is not clarified yet, estrogen and progesterone are known to regulate the function of osteoblast. Again osteoblast is reported to affect the function of osteoclast. The purpose of this study is to determine the influence of the female sex hormone, estrogen and progesterone, on the cell proliferation and activity of HOS and ROS17/2.8 cell line. The observed results were as follows. 1. Estrogen inhibited HOS cell proliferation and promoted ROS17/2.8 cell proliferation. 2. Estrogen increased the activity of alkaline phosphatase of HOS cell and reduced the activity of alkaline phosphatase of ROS17/2.8 cell. 3. Progesterone inhibited the proliferation of HOS and ROS17/2.8 cell, but had no influence on the activity of alkaline phosphatase. 4. Estrogen and progeterone did not have any particular effects on the activity of super oxide, nitric oxide and gelatinase of HOS and ROS17/2.8 cell.

Cytochrome P450 aromatase is the enzyme responsible for biosynthesis of female sex hormone(estrogen) and 19-nortestosterone(nandrolone), a unique steroid hormone endogenously synthesized in the pig. By use of RT-PCR coupled with DHPLC technique (WAVE analysis), expression pattern of isoforms of porcine cytochrome P450 aromatase gene was investigated. Relatively higher expression of aromatase mRNA was observed in testis than in ovary and this result accounted for the previous findings of higher blood estrogen level in male compared with female in this species. The result from the DHPLC demonstrated that PCR amplified DNA fragments of ovary and testis tissues. using unique PCR primers for all three types of aromatase genes, were different from those of type II and ill genes. Further nucleotide sequence analyses of the plasmid clones containing the PCR products revealed that nucleotide sequences of all clones were identical to type I aromatase gene(ovary type). Thus, the result from the present study indicates that the ovary and testis express the same type of aromatase gene. Therefore, the efficacy of DHPLC techniques used for this study helped us to analyze tissue-specific expression of isoform of genes containing the nucleotide sequences with high homology.

The purpose of this study was to investigate the estrogen-like activities of eight oriental medicines, including red ginseng, fenugreek, and dandelion. Hot water and ethanol extracts were prepared from Cervus nippon temminck (Nokgaksang), Cynanchum wilfordii (Baeksuo), Lespedeza cuneata (Yagwanmun), Panax ginseng (red ginseng), Smilax china (Toryeong), Taraxacum platycarpum (Mindeulre, dandelion), Tribulus terresteis (Namgase), and Trigonella foenum-graecum (Horopa, fenugreek). Then, estrogen-like activities were verified by the in vitro transcriptional activity assay. The extracts showing estrogen-like activities were red ginseng, Baeksuo, fenugreek, Yagwanmun, and dandelion in the ethanol extracts, and red ginseng, fenugreek, and Baeksuo in the hydrothermal extracts. Red ginseng extract showed a higher activity than the standard $10^{-8}M$ $17{\beta}$-estradiol in both the hydrothermal and ethanol extract at $500{\mu}g/ml$, while the $50{\mu}g/ml$ of the red ginseng ethanol extract and the $500{\mu}g/ml$ of the Baeksuo hydrothermal extract showed estradiol activities between $10^{-9}$ and $10^{-8}M$ $17{\beta}$-estradiol. This shows that it would be possible to contribute to the development of functional materials using red ginseng, Baeksuo, fenugreek, and dandelion.

Sella turcica contains pituitary gland that has influence on craniofacial growth. So, if the volume of sella turcica correlate to the function of Pituitary gland, we can assume that the volume of sella turcica in skeletal Class III patients has some difference to that of normal occlusion group. The purpose of this study was to evaluate the difference of shape and volume of sella turcica between normal occlusion group and Class III patients. The shape of sella turcica was Classified by Inaba method and the volume of sella turcica was measured in lateral and P-A cephalograms by Di Chiro method. To find out the possibility of the volume of sella turcica as diagnostic aid to predict Class III growth pattern, the correlation coefficients between the volume of sella and cephalometric variables were calculated. The results were as follows. 1. The volume of sella turcica in Class III patients is larger than that of normal occlusion groups 2. The volume of sella turcica in female was larger than that of male in Class III patients 3. The volume of sella turcica has close correlation with APDI, ANB, SNA, SNB, ODI, gonial angle, post. cranial base length 4. Sella Index (volume of sella / ant. cranial base length) can be a more accurate indicator that represent Class III growth pattern than volume of sella itself. 5. The morphologic pattern of sella turcica had no significant difference between two groups.
