The present study, using immunohistochemical procedure, was carried out to determine the localization of immunostainable $\beta$-endorphin cells in the mouse ovarian tissues. Mature female mice were perfused with 4% neutral buffered paraformaldehyde under anesthesia and then frozen-sections were immunostained with anti $\beta$-endorphin antiserum according to ABC technique. Immunoreactive $\beta$-endorphin was found in the luteal cells of corpus lutea, but not in the thecal cells. More strong immunostaining signak were observed in large corpus luteum, in particular, the regressing luteal cells. Primary and secondary follicles did not show any immunoreactivity of $\beta$-endorphin, but granulosa cells lining the antral cavity of large antral follicles contained immunoreactive $\beta$-endorphin.

Objectives: In this research, the effect of Gyogam-dan (GGD) on depression and immunity were assessed in ovariectomized rats subjected to repetitive stress. GGD is the prescription consisting of Poria cocos and Cyperi Rhizoma. Methods: Ovariectomized rats were repeatedly stressed over a 2-week period. After GGD (100 or 400 mg/kg) were orally administered, Elevated Plus Maze (EPM) and forced swimming test (FST) were performed to evaluate depressive and anxiety response. As well, the change of corticosterone (CORT) and the change of interleukin-$1{\beta}$ (IL-$1{\beta}$) and interleukin-4 (IL-4) in blood serum and in brain were mesured. Results: 1. In the EPM, there were no statistically significant differences among the groups. 2. In the FST, immobility time significantly decreased in rats of each experiment group compared with the control group (p<0.01). 3. Serum CORT level were decreased in 400 mg GGD group (p<0.05). 4. On IL-$1{\beta}$ and IL-4 measurement in the serum and brain, there were not significant increase or decrease compared with the control group. Conclusions: These results suggest that GGD is effective to reduce depression-behavior in ovariectomized rats. However, GGD do not has significant efficacy to reduce anxiety-behavior in EPM test. Measurement of serum CORT level reveals significant decrease and it shows anti-depressant like effect. Results on immunity are not significant.

Objectives: Samul-tang and Rhizome of Cyperus rotundus L. have been frequently used in gynecologic disease. The purpose of the present study is to explore the behavioral and neurobiological effects of Samul-tanggahyangbuja (SGH) on ovariectomized rats and to form a basis for clinical treatment. Methods: Ovariectomized rats were repeatedly stressed for over 2 weeks. After orally medicated with SGH (200 or 400 mg/kg/day), the anxiety response was tested using the Elevated Plus Maze (EPM) in rats. The serum levels of estradiol and IL-4, and immunohistochemical changes of IL-4 in the Locus coeruleus (LC) and Paraventricular Nucleus (PVN) were measured. Results: 1. In the EPM, SGH 400 mg significantly increased time spent on the open arms and decreased time spent on the closed arms, compared with the control group (p<0.05). 2. SGH tended to increase numbers of crossings in the open and closed arms in the EPM. However, it did not reach statistical significance. 3. SGH significantly increased the serum levels of estradiol compared with the control group (p<0.05). 4. SGH 400 mg significantly increased the serum levels of IL-4 compared with the control group (p<0.05). 5. IL-4 immunoreactivity was reduced in the control group compared with the normal group (p<0.05). However, SGH groups (200 and 400 mg) did not produce any significant effects on levels of IL-4 in the LC and PVN. Conclusions: These results suggest that SGH possesses the anti-depressant and immuno-modulatory effects on ovariectomized rats.

The mammalian ovary is innervated by sympathetic and sensory neurons which contribute to regulating several aspects of ovarian function, including blood flow, steroidogenesis and follicular development. The existence of a neural connection between central neurons and the ovary has been rarely reported, but the mechanism underlying integration of ovarian activity to broader neuroendocrine responses has not been reported. We have now used a viral transneuronal tracing technique combined with a conventional retrograde labeling procedure of CT-HRP to demonstrate that oxytocin-producing neurons of the hypothalamus are synaptically connected to the ovary. Since ovarian activity is suppressed but the activity of oxytocin neurons is increased during breast feeding. Our finding that the oxytocinergic neural connection is likely to provide a direct transsynaptic mechanism by which the central nervous system maintains the state of infertility that accompanies lactation in mammals.

The effects of Lycii fructus and Lycii folium on osteoporosis and serum cholesterol levels were tested in ovariectomized (OVX) rats. Twenty-four female Sprague-Dawley rats were divided into four groups: Sham group (sham-operated), Control group (OVX, ovariectomized model), LCF group (Ovx+Lycii fructus extract), and LCL group (OVX+Lycium folium extract). After 8 weeks, the OVX ($330{\pm}5.39$ g), LCF ($315{\pm}2.99$ g), and LCL ($318{\pm}2.06$ g) groups showed increased body weight compared with sham group ($281{\pm}1.71$ g). The levels of serum osteocalcin (OC) also increased in the LCF ($444.6{\pm}26.9$ ng/mL) and LCL ($407{\pm}18.9$ ng/mL) groups compared with the OVX group ($107{\pm}3.52$ ng/mL). The activities of serum alkaline phosphatase (ALP) increased in the LCF ($108{\pm}2.7$ U/L) and LCL ($407{\pm}18.9$ ng/mL) groups compared with the OVX group ($95{\pm}2.9$ U/L). Stereomicroscopy found that the low bone density that developed in the OVX group was significantly reversed in the LCF and LCL groups after 8 weeks. We also obtained molecular-based in vivo evidence that supports a mechanism of action involving novel estrogen receptor ($ER{\alpha}$) modulator in the uterus. We found that expression of ER${\alpha}$ mRNA in the OVX rat uterus was elevated by Lycium chinense. These results suggest that Lycii fructus and Lycii folium administered to rats during 8 weeks after oophorectomy may partially recover postmenopausal osteoporosis or delay the progression of osteoporotic changes.

In this study, the effect of Goheung pomegranate extract on postmenopausal syndrome was evaluated both in vitro and in vivo in ovariectomized Sprague-Dawly (SD) rats. Sixty female SD rats were divided into six groups: sham, sham operation and distilled water; OVX, ovariectomized and distilled water; PE1, ovariectomized and pomegranate concentrate (0.75 mL/twice/d); PE2, ovariectomized and pomegranate concentrate (1.5 mL/twice/d); PE3, ovariectomized and pomegranate concentrate (2.2 mL/twice/d); and CE, ovariectomized and commercial pomegranate concentrate (2.2 mL/twice/d). Percent bone volume (bone volume/tissue volume) and trabecular thickness (Tb.Th) improved in a dose-independent manner in PE1, 2, and 3. Especially, bone mineral density was significantly improved in PE3 (P<0.05) compared to OVX. Pomegranate extract reduced body weight and visceral fat mass. High density lipoprotein cholesterol (HDL-C) level slightly increased in a dose-independent manner in the experimental group. In addition, HDL-C/total cholesterol level of PE3 significantly increased (P<0.05) compared with OVX. These results show that pomegranate concentrate improved blood lipid levels and bone metabolism in ovariectomized rats. Therefore, Goheung pomegranate concentrates are expected to improve cardiovascular and bone-related diseases in menopausal women.

The present study was carried out in order to investigate the effects of antler extract on hormone concentration, Ca, P and alkaline phosphatase (ALP) levels in ovariectomized rats. Rats were ovariectomized bilaterally and were fed up with Ca- and P-free diet in order to induce osteoporosis. Osteoporosis was determined by the extent of density of bone mineral and lowering the concentrations of serum Ca and P. Male or female antler extract were administrated for 5 weeks to elucidate the protective and therapeutic effects for osteoporosis. The serum concentrations of estradiol, progesterone, calcitonin, osteocalcin, Ca and P, and the activities of ALP of ovariectomized rats were examined for 5 weeks. 1. After administration of female or male antler extract to osteoporosis-induced rats at the doses of 625 mg/kg and 1,250 mg/kg, respectively, the levels of the serum estradiol of the ovariectomized rat significantly decreased from 40.50$\pm$3.34 pg/$m\ell$ to 20.80$\pm$1.86 pg/$m\ell$ for 5 weeks, the levels of serum estradiol were a signigicant lower than those of control group (49.50$\pm$2.70~50.80$\pm$3.l3 pg/$m\ell$). 2. After administration of female or male antler extract to osteoporosis-induced rats at the doses of 625 mg/kg and 1,250 mg/kg, respectively, the levels of serum progesterone were didn't show significant differences. 3. After administration of female or male antler extract to osteoporosis-induced rats at the doses of 625 mg/kg and 1,250 mg/kg, respectively, the levels of serum calcitonin were a little higher than those of control group (0.64$\pm$0.03 ~0.68$\pm$0.04 pg/$m\ell$). 4. After administration of female or male antler extract to osteoporosis-induced rats at the doses of 625 mg/kg and 1,250 mg/kg, respectively, the levels of serum osteocalcin were little higher than those of control groups (0.28$\pm$0.02~0.31$\pm$0.02 ng/$m\ell$). In addition, the levels of serum osteocalcin of female antler extract administered group were little higher than those of male antler extract administered group. 5. The levels of serum Ca and P in osteoporosisinduced rats, administered with male or female antler extract, were little higher than those of control group. However, the levels of serum Ca and P in ovariectomized rats were significantly higher than those of control group (p＜0.05). 6. After administration of female or male antler extract to osteoporosis-induced rats, the activities of serum ALP increased compared with those of normal control group. There were significant differences between the serum ALP activities of FA 1,250 and 625 groups (p＜0.05). These findings suggest a possible protective and therapeutic effects of female or male antler extract against bone loss in ovariectomized rats, associated with a significant increase of serum estradiol level.
