The purpose of this study was to evaluate the Pathological Diagnosis associated with pSUV uptake of $^{18}F$-FDG PET/CT. We had enrolled 39 women that underwent $^{18}F$-FDG PET/CT before operative. We evaluated whether there was correlation between the pSUV of $^{18}F$-FDG PET/CT and prognostic factors. As a results, pSUV level increase according to tumor size but pSUV had no significant association with tumor size. pSUV of high histologic grade was higher than low histologic grade, and pSUV showed positive correlations with histologic grade. The ER and PR showed significant negative correlations with the pSUV of $^{18}F$-FDG PET/CT. Therefore, our results demonstrated that an correlation exists between pSUV and prognostic factors such as histologic grade, ER and PR.

The effects of $PGF2{\alpha}$ on the conception rate and the plasma levels of estradiol-$17{\beta}$ and progesterone of anestrus Cheju mares were investigated at the breeding and non-breeding seasons. The results obtained from this studies are as follows; 1. The durations of the estrus and diestrus after $PGF_2{\alpha}$ treatment persisted shorter than control cycle (p<0.05), but ovulation time was fast. 2. The levels of estradiol-$17{\beta}$ and progesteron before $PGF_2{\alpha}$ treatment showed 103.8pg/ml, 8.0ng/ml in breeding season and 72.8pg/ml, 4.7ng/ml in non-breeding season, respectively. 3. The levels of estradiol-$17{\beta}$ rose to 115.4~154.0pg/ml, and 90.8~27.0pg/ml from 2nd to 6th day after the treatment of $PGF_2{\alpha}$, in breeding and non-breeding seasons, respectively, while progesterone level dropped to 1ng/ml with the sign of estrus and at 8th day rose in breeding season (p<0.05). 4. Of thirty anestrus mares investigated for $PGF_2{\alpha}$ administration, 87.5% showed estrus on an average of 3.8 days after treatment and the conception rate was 62.5% in breeding season, but the estrus and conception rates dropped 40% and 20% in non-breeding season, respectively.

PURPOSE: Estrogen replacement therapy is indicated for the relief of hot flushes and urogenital atrophy, the prevention of osteoporosis and the reduction in risk of cardiovascular disease. The present study assessed by blood pressure, heart rate variability, and climacteric symptoms in menopausal women before treatment and at 1 month during estrogen replacement therapy. METHODS: The study sample consisted of 16 healthy menopausal women (range 49 to 59 years, mean : 53.4 years) attending menopausal clinics for the complaint of climateric symptoms at S. hospital in Chunchoen. They were all non-smokers and no patient had symptoms or evidence of cardiovascular disease. They took estrogen replacement therapy (conjugated estrogen 0.625 mg with or without medroxy progesteron 2.5mg) for 1 month. Blood pressure, heart rate variability(heart period and vagal tone) through ECG, and climacteric symptom were measured in all subjects before treatment and at 1 month during treatment. Climacteric symptom questionnaire which was developed by Neugarten et al.(1963) was modified with 20 items of question(Cronbach's alpha = 88 -.89). The data was collected from Sept. 1. 2000 to July. 30. 2001. RESULTS: There was no significant difference in mean systolic and diastolic pressure between the baseline and at 1 month during treatment. The mean heart period and vagal tone were slightly increased, but difference of mean heart period and vagal tone were not statistically significant between the baseline and at 1 month during treatment. The score of climacteric symptoms decreased significantly from the baseline after treatment. CONCLUSIONS: Even though, this study did not show that estrogen replacement therapy led decrease of blood pressure and increase heart rate variability, climacteric symptoms reduced much in all subjects after taking drugs. These results suggest that there is need to repeat study with long term period.

In the mammalian ovary the follicular fluid contains proteins and peptides which play an important role in growth, development and maturation of oocytes. The gonadotropins and some other factors work synergistically and regulate ovarian functions. In the present study the effect of follicular fluid proteins (FFP) and gonadotropins on progesterone secretion by granulosa cells (GC) from buffalo ovary, was investigated during culture. The follicular fluid was collected from small (<5 mm), and medium (5-8 mm) follicles obtained from buffalo ovaries. The follicular fluid from medium follicles was fractionated with ammonium sulphate at 80% saturation. The precipitated protein fraction was further resolved in to minor (peaks I, III) and major (peak II) proteins using gel filtration (Sephadex G-200). The FFP from small follicles and major FFP (peak II) at a dose of 200 $\mu$g/well, significantly stimulated progesterone secretion by pooled GC (3${\times}10^{5}$ cells/2 ml medium/well). The minor FFP did not show any stimulatory effect. There was a significant increase in progesterone secretion by pooled GC in presence of FFP and LH (10 ng/well), however, FSH (20 ng/well) with FFP exhibited an inhibitory effect. The major FFP and gonadotropins were also studied for their effect on progesterone production by GC isolated from medium and large size follicles. The GC from medium follicles were more responsive to FSH and FFP whereas GC from large follicles exhibited enhanced progesterone secretion with LH and FFP. These results indicated that FFP have their own stimulatory effect and also act synergistically with gonadotropins. The significantly different response shown by GC, for steroid hormone secretion, is based on their stage of growth and differentiation. The purification and characterization of such steroidogenic proteins may help in elucidating their role in growth and differentiation of granulosa cells.

Recent industrial society has human widely exposed to PAHs that are comming from the incomplete combustion of organic material as widerspread environmetal contaminants. Biological activities of PAHs are not known although PAHs are considered as carcinogens. PAHs in the mammalian cells affect CYP1A1 gene expression as well as other phase II drug metabolizing enzymes as UDPGT, NMOR etc. The mechanism of action of PAHs has been studied extensively, however it is not clear how PAHs turn on CYP1A1 in human breast cancer. Our labolatory have been studied the effect of PAHs in the human breast cancer cell lind MCF7. In this study, we examined the ZR-75-1 human breast cancer cells as a new system to evaluate bioactivity of PAHs. ZR-75-1 human breast cancer cell line has been estabilished from the breast cnacer patient, has estrogen receptors and progesteron receptors. We have been able to estbilish long term culture system of this cells then used for the study to observe the effect of PAHs. We demonstrate that PAHs induced the transcription of an aryl hydrocarbon-responsive reporter vector containing the CYP1A1 promoter and 7-ethoxyresolufin O-deethylase(EROD) activity of CYP1A1 enzyme in a concentration-dependant manner. RT-PCR analysises indicated that PAHs significantly up-regulate the constitutive level of CYP1A1 mRNA. Apparently, ZR-75-1 cells have Aryl hydrocarbon recetors, therefore it would be good experimental tool to study the cross-talk between PAHs and steroid actions.

Objectives: The present study is carried out to review the efficacy of Korean, Oriental medicine on premenstrual syndrome. Methods: We searched for 7 internet worldwide databases in order to find the studies with the keywords of 'premenstrual syndrome', 'premenstrual syndrome & Oriental medicine', 'premenstrual syndrome & traditional Chinese medicine' and 'premenstrual syndrome & herbal medicine' from 2009 to 2019. after selecting studies based on own criteria, total 8 studies are finally included. the studies were assessed with the Cochrane risk of bias criteria and reviewed systematically. Results: After intervention, cured patient rate in test groups in all of studies were significantly higher than rate in control group. there were significant decrease in headache, anorexia, dry mouth, breast mass, mastodynia, agitation, irascibility, edema, dizziness, fever, anhedonia, depression, inability to sleep, profuse dreaming with herbal medicinal intervention. 3 of those studies checked hormonal level. Estradiol (E2) and Progesteron (P) changed significantly in 2 of studies. Prolactin (PRL) in 1 study decreased significantly. FSH (Follicle stimulating hormone) and LH (Luteinizing hormone) had no significant decrease in 1 study. Conclusions: This review suggests that herbal medicine on premenstrual syndrome is effective without serious adverse effects. however, since unclear risk of bias, the result of this study should be considered carefully. further clinical trials should be carried out in order to academical clinical progress regarding treatment of premenstrual syndrome.

Purpose: Scutellaria baicalensis is a herb which has effect of eliminating heat, drying dampness, purging away fire, detoxicating. Clinically, has been used to remove fever and control of inflammation. We have studied in series to investigate the effective traditional oriental medicines of treatment for endometriosis. In this study, the effects of Scutellaria baicalensis administrated orally or rectally on surgically induced endometriosis in rat were investigated. Methods: The endometrial tissues of rats were autografted to their small intestine. Rats with surgically induced endometriosis were administered with Scutellaria baicalensis extracts for 40 days orally or rectally. We observed the tissue size of ectopic uterine implants at the mesenteric with the naked eye and examined the concentration of estradiol, progesterone, $TNF-{\alpha}$ and IL-2, IL-4, IL-6 and IL-10 in serum. Also, we inquired which was more effective between oral administration groups and rectal administration groups. Results: The size of ectopic uterine implants of orally or rectally treated groups was much smaller than those of control groups. The concentrations of estradiol, progesterone, $TNF-{\alpha}$, IL-2 and IL-6 were significantly decreased in oral administration experimental group compared with the control group. The concentrations of progesteron, $TNF-{\alpha}$, IL-2 and IL-6 were significantly decreased in rectal administration experimental group compared with the control group. The efficiency of oral administration group was better than that of rectal administration group at the serum concentration of estradiol and IL-4. Conclusion: Our data suggest that Scutellaria baicalensis inhibit the inflammation induced from ectopic uterine implants at the mesenteric wall and inhibit the growth of ectopic uterine implants. Judging from the above results, it can be suggested that Scutellaria. baicalensis should be a useful agent for inhibiting the inflammation induced from ectopic uterine implants and the proliferation of endometriosis. Maybe, oral administration of Scutellaria baicalensis is more effective than rectal administration.

This study was conducted to investigate the effects of unilateral ovariectomy on the weight of the remaining ovary, the change of number of ovarian follicle, number of corpus luteum and serum progesterone level. Sixty Sprague-Dawley female rats, 23$\pm$2 days old, were divided into 2 groups (control and unilaterally ovariectomized goup) with 30 heads per groups. Each group was again subdivided into 6 groups according to 6 experimental periods; Day 4, 8, 12, 16, 20 and 24 after uniteral ovariectomy. Five arts at every 4 day intervals were sacrificed for the measuring of ovarian weight and for quantitative histologic examination of ovary and at the same time, blood samples were taken for the determination of serum progesterone level of radioimmunoassy. The results obtained were as follows: During the experimental periods, a significant hypertrophy occured in the remaining ovary of unilaterally ovariectomized group from day 16 after operation. The average ovarian weight of control group at day 16 was 21.0$\pm$1.7mg, which is samller than that of unilaterally ovariectomized group weighing 50.5$\pm$8.4mg(P<0.01). The ovarian weight of the unilaterally ovariectomized rats at day 20 and day 24 was 75.9$\pm$2.2 mg and 63.3$\pm$7.0 mg, which is heavier than those of control group; 29.1$\pm$2.3 and 26.3$\pm$1.7 mg(P<0.01 and P<0.01). 2. A same degree of ovarian follicle development was observed in the unilaterally ovariectomized group. Following unilateral ovariectomy and there was no change in total number of follicles larger than 130$\mu$ during the period from day 4 till day 24 after operation. 3. Although the size fo ovarian follicle did not significantly change between two groups from day 4 till day 16, the size of vesicular follicle in unilaterally ovariectomized group (406.3$\pm$26.2$\mu$) was significantly greater as compared to that of control group (323.8$\pm$19.3$\mu$)(P<0.05). 4. Corpus luteum in unilaterally ovariectomized and control group began to a, pp.ar from day 16 after operation and then the number of corpus luteum slightly increased. The number of corpus luteum in unilaterally ovariectomized group at day 24 ws remarkably increased (13.7$\pm$1.41) than that of control (5.2$\pm$2.01)(P<0.01). 5. Serum progesterone levels in unilaterally ovariectomized group were slightly higher than those of control but there were no significant difference between treatment groups.
