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.

Osteoporosis is characterized by bone loss and mobidity with osteoporotic fracture. This study was performed to evaluate the effect of on the bone mass and its related factors in estrogen-deficient animal model. The model rats of osteoporsis showed a significant decrease in bone density, bone ash density, calcium content of femur bone. At the 14th day after ovariectomy-surgery, rats were administered with DBE, extract of Dioscorea batatas, per orally, and continued for 10 weeks. And osteoporosis related parameters were determined to investigate the effect of DBE. Osteoporetic rats showed lower serum estrogen level, higher body weight than normal rats, and showed atrophy of uterine horns. DBE showed inhibitory effect on bone loss in osteoporetic condition, and reduced the increase of ALP activity and osteocalcin level in serum, and reduced the increase of OH-proline level in urine. But, DBE had no effect on cell proliferation and ALP activity in rat calvarial cell culture.

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.

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.

This study was designed to investigate the effects of dietary calcium. serum estrogen level and physical activity on the bone status of 116 healthy elderly women living in urban area. Current calcium intake was assessed by convenient method(refered to as Ca intake) and calcium containing food frequency method(refered to as Ca index) Daily activity record was used for the estimation of physical activity level, and serum estrogen level was measured from fasting blood of subjects. The rate of bone resorption was evaluated by the determination of hydroxyproline(Hpr) in fasting urine with correction for creatinine excretion. The results of this study are summarized as follows : 1) Average daily Ca intake of subjects was 621.4$\pm$155.8mg, which is above the Korean recommended dietary allowances. However 44.8% of the subjects consumed Ca below RDA level. Ca index score was significantly correlated with the bone status(P<0.05), Ca intake did not show significant correlation with the bone status although a positive trend of influence was evident. 2) Average serum estrogen level of subjects was 18.7$\pm$9.8pg Contrary to our anticipation. estrogen level did not show any significant relation to age and bone status. 3) Daily physical activity was classified into four categories by activity intensity : sedentary. moderate, active and severe. The average physical activity of subjects belong to moderate level. and the bone status was significantly related to the physical activity(P<0.01) 4) Among other influential factors such as age, pocket-money. family type. drinking, smoking and BMI, there was a significant difference between bone status and BMI(P<0.05). 5) Multiple regression analysis of variables showed that physical activity has greater effect than other variables when the entire subjects were taken into account. However. eliminating the subjects whose bone status rated as excellent(Hpr/cr<0.009), Ca index showed higher correlation than physical activity. These results have demonstrated that dietary calcium intake is the primary important factor for keeping good bone health and that bone status of subjects with a sufficient calcium intake is affected by various factors such as physical activity, age, smoking. BMI and others.

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.

Objectives : To investigate the effect of Taxilli Ramulus (TR) extract on bone metabolism of ethanol-treated animal model. Methods : The changes of serum calcium, calcitonin, estrogen level, a1ka1ine phosphatase activity, osteocalcin, parathyroid hormone content and urine calcium level were observed with ethanol treatment for 60 days. The results were compared with an ethanol- TR extract double treatment group. Results : We observed increment of serum osteocalcin, parathyroid hormone content, alkaline phosphatase activity and urine calcium level by chronic ethanol feed and they were recovered to near normal level with Taxilli Ramulus extract treatment. Weight gain, serum calcium level, calcitonin and estrogen content were remarkably reduced with ethanol treatment and their levels were normalized by Taxilli Ramulus extract. Conclusions : These results showed that Taxilli Ramulus extract have the ability to recover to normal in the body an abnormal calcium metabolism process due to external factors. These results suggested that Taxilli Ramulus extract have preventive effects on calcium concentration loss and osteoporosis.

Objectives: Taraxaci Herba (TH) have been used in oriental medicine for many centuries as a heat-clearing, detoxifying and stimulating milk secretion drug. Therefore, the purpose of this study was to investigate the effects of TH on the sex hormone changes and lipid metabolism in the experimental model. Methods: The experimental model of menopause was induced by bilateral ovariectomy in rats. We used TH extract with freeze-dried and $200{\pm}20g$ female Sprague-dawley rats for this Study. The level of serum total cholesterol, serum triglyceride, serum HDL-cholesterol, serum total estrogen, serum progesterone, serum follicle stimulating hormone (FSH), and body weight were measured. Results: The results of this study were obtained as follows; 1. Sample A and Sample B significantly decreased body weight and level of serum total cholesterol, and significantly increased level of serum total estrogen as compared with control group. 2. Sample A decreased level of serum triglyceride, and was increased level of HDL-cholesterol, serum progesterone, serum FSH as compared with control group. 3. Sample B significantly increased level of HDL-cholesterol, serum FSH as compared with control group. 4. Sample B decreased level of serum triglyceride, and was increased level of serum progesterone as compared with control group. Conclusions: These results suggest that TH could be applied effectively on the treatment of menopausal syndrome.

To investigate the effect of estrogen and dietary protein level on Ca metabolism, female rats were undergone ovariectomy or sham-operation. Ovariectomized rate were divided into either estrogen-or vehicle-treated groups. Each treatment group was again divided into 40%-casein(H) or 10%-casein(L) diet groups. All experimental diets contained 0.2% Ca, 0.4% P and fed to rats for 8 weeks. Apparant Ca absorption and Ca balance were not affected by dietary protein level and ovariectomy, however they were increased by estrogen injection and this effect was even higher in low protein groups. Urinary Ca excretion were higher in high protein groups. GFR was not affected by dietary protein level, ovariectomy, or by estrogen injection. Urinary protein excretion was higher in high protein groups, which implies that the kidney funtion was deteriorated by high protein diet, and this may account partly for the higher urinary Ca in high protein groups. Ovariectomy or estrogen treatment had no effect on urinary protein excretion. Urinary hydroxyproline was higher in ovariectomized rats and increased in high protein grous. Elevated value of ovarictomized rats was lowered by estrogen injection, especially in low protein group. Alkaline phosphatase tended to increase in ovariectomized groups and lowered with estrogen treatment, but this difference was not statistically significant. Serum PTH was not affected by ovariectomy and dietary protein level. Therefore the increased hydroxproline excretion does not seem to be attributed to PTH. Dietary protein level, ovariectomy and estrogen treatment did not affect the weights and components of femur, scapular, and 4th vertebra. Ash/wt ratio of femur was, however, lower in ovariectomized rats and increased with estrogen treatment. Therefore, among the bones studied, femur seemed to be the most vulnerable. The results of this study shows that estrogen treatment may alleviate or reduce bone loss in postmenopausal women somewhat, especially for those people with low protein diet.
