Purpose: The purpose of this study was to verify the effect of aromatherapy program on lowering body mass index and serum estrogen in obese post-menopause women. Method: One group Pretest-posttest experimental design was used. All subjects received intervention of aromatherapy program. The participants used 3% grapefruit oil, cypress and three other kinds of oil. BMI and Serum estrogen level of the participants' were measured by ZEUS 9.9(Resource Medical, 2004) and PACKARD Gamma Counter-Cobra II RI Manual(USA, 1997) before and after interventions being applied at the P. hospital. Data were analyzed by paired t-test using the SPSS/PC+Win 12 Version. Result: The level of serum estrogen and BMI of the participants were significantly decreased after aromathetapy program. Conclusion: These results suggest that the effect of aromatheapy program could be utilized as an effective intervention to reduce BMI and serum estrogen level in obese post-menopause women.

Supplementation of serum and estrogen in in vitro maturation(IVM) medium was shown to improve embryo development and quality in several species. This study investigates the effect of ovarian estrus stage on canine oocyte quality and supplementation of medium with canine serum or estrogen on IVM of canine oocytes. As results, in experimental 1, IVM oocytes collected from follicular stage ovaries to MII stages($10.2{\pm}1.5%$) was higher (p<0.05) with 10% canine estrus stage serum than control($1.3{\pm}1.6%$), anoestrus stage serum($4.0{\pm}1.6%$), luteal stage serum($2.7{\pm}1.7%$) and 10% FBS($1.3{\pm}1.6$). In experimental 2, 10% canine estrus stage serum supplementation has highest maturation rate to MII stages($10.0{\pm}1.8%$) and there were significant differences(P<0.05) with another treatment in follicular stages group. In order to investigate the synergic effect of estrous serum and estrogen supplementation, different estrous stage groups of oocytes were cultured with 2 ug/ml estrogen plus various concentrations of different reproductive stage serum and FBS(experimental 3). As results, the rate of maturation to metaphase II(MII) stage was significantly higher(p<0.05) in oocytes from the follicular stage supplemented with estrogen and 10% canine estrus stage serum(11.5%) compared to the other groups(6.0 - 8.8%). The present study was demonstrated that canine serum and the estrus cycle of the bitch affect the meiotic competence of oocytes. Hormonal influences within the follicle may be one of the factors responsible for the greater proportion of maturation of oocyte to MII from bitches at the follicular phase.

Effect of Gamisamul-tang(GS) on body weight, uterine weight, splenial weight, serum and estrogen receptor-α (ER-α) in kidney were investigated in ovariectomized(OVX) rats. Female Sprague -Dawley rats with a body weight of 220 g were undergone ovariectomy or sham operation. The ovariectomy caused significant decrease in serum levels of HDL-cholesterol and in uterine weight compared to those of sham-operated animals. while caused significant increase in serum levels of total cholesterol, LDL-cholesterol, triglyceride, body weight and in splenial weight. In contrast, administration of OVX rats with the GS significantly elevated serum levels of HDL-cholesterol and uterine weight, but significantly depressed serum levels of total cholesterol, LDL-cholesterol, triglyceride, body weight and in splenial weight. ER-α localized in the kidney vessel endothelial cells and its expression was increased by ovariectomy and decreased by administration of OVX rats with the GS. Our results suggest that a possible protective effect of as against hyperlipidemia in postmenopausal cardiovascular disease and as increase the estrogen-estrogen receptor romp/ex in the kidney vessel endothelial cells.

This study was trying to find what physical changes occurred to albumin when it reacted with estrogen and other ligands. Each concentration of human serum albumin with 100$\mu$l estradiol reacted at the highest binding capacity of 280nm. In addition, 1 hr of reaction time showed the highest binding rate. Conformational changes in human serum albumin with dietylstillbesterol and N-ethyl-maleimide produced strong binding capacities. The changes were immediate and they did not increase or decrease over time. Effects of human serum albumin with estriol induced no interaction each other. The binding capacity of human serum albumin with vitamin D$_2$was lower than estradiol. and the highest binding rate showed 1 hr of reaction time. Vitamin D$_2$ was very similar to the binding capacity of estradiol.

This study was conducted to find out the effects of estrogen and progesterone on body weight, uterine weight and serum prolactin levels on the growing female rats which were ovariectomized. For this purpose, 125 heads of rats (Wistar-Imamichi strain), 28 days old, were devided into 5 groups; OVariectomy(Ovx.), ovariectomy treated with estrogen(Ovx.+Est.), ovariectomy treated with progesterone(Ovx.+Prog.), ovariectomy treated with estrogen and progesterone(Ovx.+Est.+Prog.) and control group. Twenty-five heads of rats were arranged to each group, and changes of body weights were weekly checked. On the other hand, every 5 heads of rats in each group were sacrificed at 1, 2, 3, 4 and 5 weeks after treatments with time elapse for measuring concentrations of serum prolactin and for investigating the weights of ulterus. Prolactin concentrations in the serum were analyzed by radioimmunoassay. The results obtained are as follows; 1. The body weights were increased slightly in Ovx. in comparison with Ovx.+Prog., Ovx.+Est.+Prog., Ovx.+Est. and control groups, but there were not significant among the compared groups at all observation times. 2. The uterine weights in all treatment groups were decreased significantly (P<0.01) compared with control groups at all observation times. But the weights in Ovx. and Ovx.+Prog. groups were lower than those in Ovx.+Est. and Ovx.+Est.+Prog.. 3. Serum prolactin concentrations were increased slightly in control group in comparison with other groups at 1 and 2 weeks increased slightly in control group in comparison with other groups at 1 and 2 weeks after treatment. But compared with control group, the concentrations Ovx.+Est. and Ovx.+Est.+Prog. were high level, and those in other groups were low level in the order of Ovx. and Ovx.+Prog. groups at 3, 4 and 5 weeks after treatment. There were not significant among the compared groups at all observation times. 4. The results obtained in this study suggest that when ovariectomized rats receive 1$\mu$g estrogen and 3mg progesterone daily, that had no effect on body weight and serum prolactin concentrations while significantly effect on the weight of uterus.

It has been suggested that dietary fat increases the risk of breast cancer by elevating serum estrogen concentrations. However, studies on a relationship between fat intake and breast cancer risk have shown contradictory results, possibly because the levels of fat intake in study populations were too high to observe differences. Also, the effect of other dietary factors may present. The present study was performed to investigate the relationship between diet and estrogen metabolism in premenopausal women whose usual fat intake is relatively low compared to their western counterparts. Twenty lacto-ovo vegetarians (LOV) and twenty omnivores participated in the study. Three day food records including a Saturday or a Sunday were used to estimate nutrient intake. Serum lipids, estradiol, sex-hormone binding globulin, and urinary estradiol were measured. Study results showed $24.8\%$ and $20.9\%$ of energy intake were provided from fat in omnivorous and LOV subjects, respectively. Serum and urinary levels of estradiol were two times higher in omnivores. Fat intake was not related to either serum estradiol nor urinary estradiol when the Spearman correlation coefficient analysis was performed. Carbohydrate, total dietary fiber and soluble dietary fiber intakes were negatively related to serum estradiol concentration. Legumes, vegetables and fruit consumption showed significantly negative relationships with both serum and urinary estradiol concentrations. These results indicate lower estrogen availability may be associated with plant food­based diets in premenopausal women whose usual diets contain less than $25\%$ of energy as fat.

Objectives: This study was conducted to evaluate the effects of Pueraria lobata (PL) extract on obesity related hormones in rats with estrogen deficiency. Methods: The experiments were performed with the use of ovariectomized rats as estrogen-deficient obesity rat model. They were grouped Normal (sham operation group), Control (ovariectomy group), 50 mg/kg PL (ovariectomy group＋50 mg/kg of PL), 100 mg/kg PL (ovariectomy group＋100 mg/kg of PL), 200 mg/kg PL (ovariectomy group＋200 mg/kg of PL). PL extract was orally administered for 8 weeks once a day. Body weights and serum levels of hormones, such as leptin, estradiol, cholecystokinin (CCK), ghrelin, and adiponectin were estimated by ELISA. Results: PL extract significantly decreased body weight, the serum levels of leptin in estrogen-deficient obesity rats. PL extract significantly increased the serum levels of estradiol and CCK. However, PL extract did not directly effect on the levels of ghrelin and adiponectin in estrogen-deficient obesity rats. Conclusions: It is concluded that PL extract reduced body weight, and regulate the hormones related to energy metabolism. PL extract decreased the serum levels of leptin. PL extract increased the serum levels of estradiol and CCK. These results indicate that PL might have potentials for treatment of obesity and complications during the menopause caused by estrogen-deficiency.

After infection of male mice with the plerocercoids (spargana) of Spirometra mansoni, serum levels of estrogen and testicular weight were analyzed by enzyme-linked immunosorbent assay (ELISA) and weighing machine, respectively. The serum level of estrogen increased progressively in infected mice compared with normal controls, whereas the testicular weight of infected mice decreased significantly (P < 0.05). These results suggest that certain substances from spargana change the steroid hormone metabolisms in the host by unknown pathways, and chronic infection may contribute to change of the function of steroid hormone target organ, i.e., testis, in male mice.

The effect of calcium gluconate on estrogen (estradiol) serum level as well as follicle stimulating hormone level was studied. Our results revealed that oral administration of calcium gluconate (100 mg/kg body wight) to adult non-pregnant female rabbits caused a significant increase of serum levels of estradiol and follicle stimulating hormone. On the other hand, oral contraceptive (Norminest tablets) decreased significantly follicle stimulating hormone serum level, while combined administration of calcium gluconate and oral contraceptive caused significant increase of serum level of follicle stimulating hormone compared with control values. Also, concurrent administration of calcium gluconate and Norminest tablet increased significantly the rate of conception compared with group recieved Norminest tablets only. These results indicated that combined administration of calcium and oral contraceptives must be cautiously.

To determine the effects of endogenous and exogenous strogen on serum lipid levels, twenty nonsmoking healthy Korean women were participated in this experiment for 12 weeks. They were assigned to three groups : (1) eight women aged 22 to 30(yr) for the premenopausal(Pre) group, (2) eight, aged 49 to 60(yr) for the postmenoparusal(Pst) group, (3) four, aged 23 to 30(yr) for the oral contraceptive(OC) group which used triphasic OC formulation. Fasting blood samples representing every phase of the hormonal levels were obtained from the subjects of the Pre and the OC group. From the subjects of the Pst group, fasting blood samples were obtained once per three weeks for 12 weeks. All the serum data were adjusted for dietary effects, exercise, personality type and body mass index(BMI) by using analysis of covariation(ANCOVA). Serum lipid levels of the three groups were significantly different. While serum levels of triglycerides(TG)(p<0.0001), low density lipoprotein-chloesterol(LDL-C)/high density liporotein-cholesterol(HDL-C) ratio (LDC-C/HDL-C)(P<0.01) and total cholesterol (TC)/HDL-C ratio (TC/HDL-C)(P<0.001) were significatnly high in the Pst group, serum HDL-C(P0.001) level was significantly high in the Pre group. The OC group showed significantly low serum TC(P<0.0001) and LDL-C(P<0.0001) levels. There was no signidicant difference in the fluictuation of serum lipid levels during the menstrual cycle of the Pre group. However, in the OC group, serum TG level was significantly increased at phase 2(P<0.05) where exogenous estrogen administration was highest. Even though other serum lipid levels of the OC group were not significantly fluctuated according to the exogenous estrogen administration, there was a trend of increased levels of serum TC, LDL-C, LDL-C/HDL-C and TC/HDL-C and decreased level of HDL-C during the menstruation period. Also, serum TC level was high(P<0.005) and serum TG level was low (P<0.005) at the baseline of the OC group compared with the periods of OC administration. When screening and counseling the female population at risk for coronary heart disease(CHD), the result of this study suggest that in may be desirable to divide the population into several groups according to their personal physiological characteristics, such as age, OC administration, menstrual cycle and menopause, as well as general risk factors for CHD.
