  • Osteoporosis is recognized as one of the major hormonal deficiency diseases, especially in menopausal women and the elderly. When estrogen is reduced in the body, local factors such as IL-1 $\beta$ and IL-6, which are known to be related with bone resorption, are increased and promote osteoclastogenesis, which is responsible for bone resorption. In the present study, we investigated whether glucosidic isoflavones (Isocal, PIII) extracted from Sophorae fructus affect the proliferation of osteoblasts and prevent osteoclastogenesis in vitro by attenuating upstream cytokines such as IL-1$\beta$ and IL-6 in a human osteoblastic cell line (MG-63) and in a primary osteoblastic culture from SD rat femurs. Interestingly, IL-1$\beta$ and IL-6 mRNA were significantly suppressed in osteoblast-like cells treated with 17$\beta$-estradiol (E2) and PIII when compared to positive control (SDB), and this suppression was more effective at $10^{-8}$% than at the highest concentration of $10^{-4}$%. In addition, these were confirmed in protein levels using ELISA assay. In the cell line, the cells showed that E2 was the most effective in osteoblastic proliferation over the whole range of concentration ($10^{-4}%-10^{-12}$%), even though PIII also showed the second greatest effectiveness at $10^{-8}$%. Nitric oxide (NO) was significantly (p<0.05) upregulated in PIII and E2 over the concentration range $10^{-6}% to 10^{-8}$% when compared to SDB, without showing any dose dependency. In bone marrow primary culture, we found by TRAP assay that PIII effectively suppressed osteoclastogenesis next to E2 in comparison with SDB and culture media (control). In conclusion, these results suggest that local bone-resorbing cytokines can be regulated by PIII at lower concentrations and that, therefore, PIII may preferentially induce anti-osteoporosis response by attenuating osteoclastic differentiation and by upregulating NO.

  • This investigation studied the effect of ovariectomy on the temporomandibular joint (TMJ) of rat. Forty female Sprauge-Dawley strain white rats, each weighing about 200grams were used and divided into two groups. The one group was performed ovariectomy, and the other was performed sham operation. Both group were killed at the intervals of 3 days, 1, 2, 4, and 8 weeks postoperatively, paraffin section were stained with H&E, MT and histomorphometric study of the TMJ was performed in a synchronous manner with an sham operated control group The result were as follows: 1. At 4 weeks after ovariectomy, an adhesion between the inferior surface of the articular disc and the condyle was observed in the central portion. At 8 weeks after ovariectomy, a focal thickening of the bone (osteophyte) was observed in anterior portion and there was a marked decrease in the trabecular bone in the posterior region. 2. The thickness of cartilage zone was increased at 2 weeks postopratively in the central portion, and decreased at 4 weeks postopratively in the posterior portion. The thickness of transitional zone was decreased at 1 week postoperatively in the anterior and proliferating zone was decreased postoperatively. The thickness of articular zone was decreased at 3 days postopratively in the anterior portion, and decreased at 1 week postoperatively in the central portion. From the above finding, we could conclue that estrogen deficiency in rats causes alteration of TMJ in marked early stage.

  • Estrogen deficiency in peri-and postmenopausal women results in variety of neurovegetative, psychic and somatic symptoms, and may contribute to severe diseases within the aged female population. Capsosiphon fulvecense (CF), green algae, loaded with large amount of proteins, calcium and ion. This seaweed is distributed in the Southern coast in Korea and widely throughout the world. Our objective was to investigate the effects of Capsosiphon fulvecense (CF) extract on serum lipid concentration and platelet aggregation in ovariectomized rats. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rats (Sham), ovariectomized control rats (OVX-Control), ovariectomized rats supplemented with CF at 50mg/kg bw/d (OVX-CF5O) and ovariectomized rats supplemented with CF at 200mg/kg bw/d (OVX-CF200). The serum triglyceride level was significantly decreased after supplemented with the CF extracts. The serum HDL-cholesterol level in the OVX-CF group was significantly higher than the level in the OVX-control group. The ability of platelet aggregation treated with CF extract (CF group) was $7\%$ less than OVX-control group. Taken these together, CF extract may be used to improve the quality of life in menopausal women.

  • Osteoporosis is prevalent in elderly women and it may cause dental implant failure. In particular, estrogen deficiency in postmenopausal women leads to higher rates of osteoporosis prevalence. Immune cell-mediated effects involving the development of osteoporosis have been studied previously; however, the role of IL-10-producing regulatory B (B10) cells in osteoporosis is largely unclear. Here, we examined the role of B10 cells in osteoporosis. C57BL/6 mice were subjected to ovariectomy (OVX). Fifteen weeks after OVX surgery, the first molar of the right maxillary was extracted, and twenty-four weeks after OVX surgery, serous progression of osteoporosis was observed in the alveolar bone. Moreover, the proportion of CD19+CD5+CD1dhigh regulatory B cells, B10, and CD4+CD25+FoxP3+ regulatory T cells from the spleen of OVX mice decreased during the progression of osteoporosis, compared to controls. In contrast to regulatory cells, IL-17-producing Th (Th17) cell levels were increased in OVX mice. Adoptive transfer of B10 cells to OVX mice led to a decrease in Th17 cell abundance and inhibited the development of osteoporosis in the alveolar bone from OVX mice. Thus, our results suggest that B10 cells may help suppress osteoporosis development.

  • Estrogen deficiency in peri- and postmenopausal women results in variety of neurovegetative, psychic and somatic symptoms, and may contribute to severe diseases within the aged female population. Ecklonia stolonifera (ES) is an edible brown algae traditionally used in fishery towns in Far East Asia. This study was performed to investigate the effects of ES extracts on blood flow and serum lipid concentration in ovariectomized rats. Weight-matched female Sprague-Dawley strain rats were assigned to four groups. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-CON), ovariectomized rats supplemented with ES extract at 50 mg/kg bw/day (OVX-ES50) and ovariectomized rats supplemented with ES extract at 200 mg/kg bw/day (OVX-ES200). Serum total cholesterol and triglyceride contents decreased in the sham group compared to the OVX-CON group. Six weeks feeding of ES extract resulted in a significant (p<0.05) lowering of serum triglyceride and a lowering tendency of total cholesterol level. The level of Hdl-cholesterol in serum increased by supplementation of ES extracts at 50 mg/kg and 200 mg/kg bw/day (p<0.05). Blood passage time of the ES extracts-supplemented group was higher than the OVX-CON group. The ability of platelet aggregation of groups treated with ES extracts was less than that of the OVX-CON group. These results suggest that the beneficial effects of ES extract may be used to possibly improve on the metabolic syndrome of menopausal women.

  • This study was conducted to evaluate suppressive effects of black rice aleurone layer extract (BRE) on body fat, serum lipid, and hormone levels in ovariectomized rats. The rats were divided into five groups (n=8/group): sham operated group (S); ovariectomized control group (OVX); ovariectomized group treated with isoflavone 10 mg/kg B.W. (IF); ovariectomized group treated with BRE 30 or 90mg/kg B.W. (BRE-30 or -90). High fat diet (45% calories from fat) was fed to all rats for 12 weeks. Body weight gain, body fat weight, and adiposity index increased in the OVX group, but they significantly decreased in IF or BRE supplementation. Serum triacylglycerol and leptin levels decreased in BRE groups while serum adiponectin level significantly increased compared to that of the OVX group. Hepatic total lipid, triglyceride, and cholesterol levels increased in the OVX group, but they decreased in BRE supplementation (p>0.05). These data suggest that black rice aleurone layer may be a useful food source to decrease obesity and its related diseases by modulating lipid metabolism in estrogen-deficiency model.

  • Phytoestrogens derived from plants and foods, which are diphenolic compounds with structural similarities to natural and synthetic estrogens, have been shown to estrogenic and antiestrogenic actions. Particularly, recent study revealed that phenolic compounds in safflower seed, such as serotonin derivatives, lignans and flavonoids, could be acted as phytoestrogens. Safflower (Carthamus tinctorius L.) seed extract (SID C.SE), therefore, are receiving a renewed interest as potential therapeutic source against skin wrinkles induced by estrogen deficiency. This study was conducted to investigate the anti-wrinkle effect of SID C.SE on normal human fibroblasts through the expression of type I procollagen and UVA-induced MMP-1 in vitro. The SID C.SE increased the type I procollagen expression, comparable to trans-retinol and reduced UVA-induced MMP-1 expression in a dose-dependent manner. The clinical study indicated that cream group treated with $0.1\%$ SID C.SE significantly reduced a skin wrinkles, as compared with a control (non-treated cream group) (p<0.05). These results suggest that the safflower seed extract may be useful as potential source of anti-wrinkle cosmetics.

  • Objective: The aim of this study was to investigate microRNAs (miRNAs) related to follicle-stimulating hormone (FSH) responsiveness using miRNA microarrays and to identify their target genes to determine the molecular regulatory pathways involved in FSH signaling in KGN cells. Methods: To change the cellular responsiveness to FSH, KGN cells were treated with FSH receptor (FSHR)-specific small interfering RNA (siRNA) followed by FSH. miRNA expression profiles were determined through miRNA microarray analysis. Potential target genes of selected miRNAs were predicted using bioinformatics tools, and their regulatory function was confirmed in KGN cells. Results: We found that six miRNAs (miR-1261, miR-130a-3p, miR-329-3p, miR-185-5p, miR-144-5p and miR-4463) were differentially expressed after FSHR siRNA treatment in KGN cells. Through a bioinformatics analysis, we showed that these miRNAs were predicted to regulate a large number of genes, which we narrowed down to cytochrome P450 family 19 subfamily A member 1 (CYP19A1) and estrogen receptor alpha (ESR1) as the main targets for miR-4463. Functional analysis revealed that miR-4463 is a regulatory factor for aromatase expression and function in KGN cells. Conclusion: In this study, we identified differentially expressed miRNAs related to FSH responsiveness. In particular, upregulation of miR-4463 expression by FSHR deficiency in human granulosa cells impaired 17β-estradiol synthesis by targeting CYP19A1 and ESR1. Therefore, our data might provide novel candidates for molecular biomarkers for use in research into poor responders.
