This study was conducted to investigate the effect of beef bone extracts on the organoleptic quality and fermentation of Baeck Kimchi. For this study, the organoleptic characteristics of Baeck Kimchi, with addition beef bone extracts were tested, and the changes in the fermentation factors, such as pH, acidity, reducing sugar and total microbial count, were observed during fermentation at 10$^{\circ}C$ and 20$^{\circ}C$. Greater amounts of lipids and soluble nitrogen were extracted to increasing the boiling time for the preparation of the beef bone extracts. However, 1% of the mixed beef bone extracts, prepared by boiling for 5, 7 and 9 hours, was the most acceptable for the Baeck Kimchi fermentation, as assessed from the results of sensory consumer tests. The beef bone extracts enhanced the umami taste of the unfermented Baeck Kimchi. The carbonated taste, sourness and fresh flavor of the fermented Baeck Kimchi were also enhanced. The fermentation rate was increased by the addition of beef bone extracts to Baeck Kimchi.

Yam extracts (Dioscorea batatas) have been reported to possess a variety of functions. However, studies on its osteogenic properties are limited. In this study, we investigated the effect of ethanol and water extracts on osteoblast proliferation and bone matrix protein synthesis, type I collagen and alkaline phosphatase (ALP), using osteoblastic MC3T3-E1 cell model. MC3T3-E1 cells were cultured with yam ethanol and water extracts (0~30 mg/L) within 39 days of osteoblast differentiation period. Cell proliferation was measured by MTT assay. Bone matrix proteins were assessed by the accumulation of type I collagen and ALP activity by staining the cell layers for matrix staining. Also, the secreted (media) matrix protein concentration (type I collagen) and enzyme activity (ALP) were measured colorimetrically. Yam ethanol and water extracts stimulated cell proliferation within the range of 15~30 mg/L at 15 day treatment. The accumulation of type I collagen in the extracellular matrix, as well as secreted collagen in the media, increased with increasing doses of yam ethanol (3~15 mg/L) and water (3~30 mg/L) extracts. ALP activity was not affected by yam ethanol extracts. Our results demonstrated that yam extracts stimulated osteoblast proliferation and enhanced the accumulation of the collagenous bone matrix protein type I collagen in the extracellular matrix. These results suggest that yam extracts may be a potential activator for bone formation by increasing osteoblast proliferation and increasing bone matrix protein type I collagen. Before confirming the osteogenic action of yam, further studies for clarifying how and whereby yam extracts can stimulate this ostegenesis action are required.

The preventive effects of Sophorae Fructus extracts (I: hot water extract and II: combination product using I) on bone loss in ovariectomized (OVX) rats were investigated. Sophorae Fructus extracts were orally administrated to OVX rats for 9 weeks. Ovariectomy caused the increase of body weight and deoxypyridinoline (Dpd: bone resorption marker) and decrease of calcium (Ca: bone formation marker) level in serum. Dpd level were significantly decreased and Ca levels were elevated at 9 weeks in Sophorae Fructus extracts administered groups after ovariectomy at a dose of 0.556 g/kg/day compared with control group. In administered groups, trabecular bone area (TBA) in the tibia and lumbar were also increased compared with control group in histomorphological analysis. The preventive or treatment effects of Sophorae Fructus extracts on bone loss in OVX rats appears to be due to suppression of bone turnover.

In this research, the genotoxic effects of Pinelliae Rhizoma (PR) extracts, one of famous herbal agents in Korean medicine were evaluated using the mouse micronucleus test. PR extracts was administered once a day for 2 continuous days by oral gavage to male ICR mice at doses of 2000, 1000, and 500 mg/kg. Cyclophosphamide was used as a known genotoxic agent in a positive control. The appearance of a micronucleus is used as an index for genotoxic potential. No PR extracts treatment-related abnormal clinical signs, body weight changes and mortalities were detected. Significant (p<0.01) increases of the numbers of polychromatic erythrocytes contain micronucleus in prepared bone marrow cells were detected in CPA and PR extracts 2000 mg/kg treated groups as compared with intact control, respectively. The results of intraperitoneal dose mouse bone marrow cell micronucleus test of PR extracts were positive in the present study. It is considered that there were no problems from cytotoxicity of PR extracts tested in this study because the polychromatic erythrocyte ratio was detected as > 0.42 in all tested groups.

Background: Breast cancer is the most common malignant disease in women. The patients with advanced breast cancer develop metastasis to bone. Bone metastasis and skeletal-related events by breast cancer are frequently associated with the invasiveness of breast cancer cells and osteoclasts-mediated bone resorption. Forsythia koreana is used in oriental traditional medicine to treat asthma, atopy, and allergic diseases. The aim of this study was to evaluate the inhibitory effects of F. koreana extracts on the invasion of breast cancer cells and bone resorption by osteoclasts. Methods: Cell viability was measured by an MTT assay and the migration and invasion of MDA-MB-231 cells were detected by a Boyden chamber assay. The formation of osteoclasts and pit was detected using tartrate-resistant acid phosphatase staining and calcium phosphate-coated plates, respectively. The activities of matrix metalloproteinases (MMPs) and cathepsin K were evaluated by gelatin zymography and a cathepsin K detection kit. Results: The fruit and leaf extracts of F. koreana significantly inhibited the invasion of MDA-MB-231 cells at noncytotoxic concentrations. The fruit extract of F. koreana reduced the transforming growth factor ${\beta}1-induced$ migration, invasion and MMPs activities of MDA-MB-231 cells. In addition, the fruit, branch, and leaf extracts of F. koreana also inhibited the receptor activator of nuclear factor kappa-B ligand-induced osteoclast formation and osteoclast-mediated bone-resorbing activity by reducing the activities of MMPs and cathepsin K. Conclusions: The extracts of F. koreana may possess the potential to inhibit the breast cancer-induced bone destruction through blocking invasion of breast cancer cells, osteoclastogenesis, and the activity of mature osteoclasts.

Objectives : This study was performed to evaluate the effects of water extract of Cervi Parvum Cornu(CPC), Aconiti Lateralis Radix Preparata(ALR), and Yongbu-tang(YBT) on suppression of the receptor activator of nuclear factor kappa-B ligand(RANKL)-induced osteoclast differentiation and bone resorption. Methods : The effects of CPC, ALR, YBT extracts on osteoclast differentiation were determined by culture of bone marrow macrophage(BMM). The mRNA expression levels of the nuclear factor of activated T-cells cytoplasmic 1(NFATc1), c-Fos and tartrate-resistant acid phosphatase(TRAP) in BMMs were analyzed by reverse transcriptase polymerase chain reaction(RT-PCR). Similarly, the protein expression levels of NFATc1, c-Fos, mitogen-activated protein kinase(MAPK)s and ${\beta}$-actin in cell lysates were measured by western blotting. In addition, effects of CPC, ALR and YBT extracts were determined by means of Lipopolysaccharide(LPS)-induced bone-loss with mice. Results : CPC, ALR and YBT extracts showed remarkable inhibition on RANKL-induced osteoclast differentiation without cytotoxicity. CPC and ALR extracts significantly reduced the protein expression level of NFATc1. YBT extract significantly reduced the mRNA expression levels of c-Fos, NFATc1 and the protein expression levels of c-Fos, NFATc1, AKT, p38, c-Jun N-terminal kinase(JNK). Further, YBT extract suppressed degradation of$ I-{\kappa}B$. And ALR extract significantly restored the bone erosion by LPS treatment in mice. Conclusions : YBT extract showed more remarkable inhibition on osteoclast differentiation than CPC and ALR extracts in vitro. ALR extract showed remarkable inhibition on bone resorption in vivo. Thus, YBT extract can be a useful treatment for bone-loss diseases such as osteoporosis.

Interieukin 1${\beta}$ is a potent bone resorptive cytokine which mediates soft tissue destruction through the stimulatidn of prostaglandin production and the induction of collagenase. This constellation of activities suggests a role of IL-1${\beta}$ in the pathogenesis of periodontal disease. The purpose of this study was to evaluate the effects of herbal extracts on production and activity of IL-1${\beta}$. When LPS was added to cultured human blood monocytes, the effects of herbal extracts on the production of IL-1${\beta}$ was evaluate by thymocyte stimulation assay. When rHuIL-1${\beta}$ was added to cultured human gingival fibroblasts, the effects of herbal extracts on production of $PGE_2$ was evaluated by ELISA and when it was added to cultured mouse calvaria, the effects on bone resorption was estimated by .$^{45}Ca$-release bone resorption assay. The herbal extracts that had been used in this study were as follows; Asparagi Radix, Schzandrae Fractus, Zizyphi Fractus and Rhois Galla. The following results were obtained from this study. 1. All these extracts effectively inhibited the production of IL-1${\beta}$ on cultured human blood monocytes. 2. All these extracts effectively inibited the production of $PGE_2$ on cultured human gingival fibroblasts. 3. All these extracts did not effectively inhibit the bone resorption induced by rHulL-1${\beta}$ on cultured mouse calvaria.

Objective: Animal feed companies and researchers are currently embarking on quests for feed additives that could combat the pathogens while promoting growth as well as maintaining quality products. The current study aimed to evaluate the effects of onion extracts on growth performance, carcass quality, and bone morphometrics of broiler chickens. Methods: A total number of 200 one-day-old unsexed Ross 308 broiler chicks were assigned to 5 treatment groups, replicated 4 times. Each replicate (pens) held 10 chickens in a completely randomized design. The experimental diets were then randomly allotted to the pens which act as experimental units. The isoenergetic and isonitrogenous diets were formulated by including onion extracts at 0, 5, 10, 15, or 25 g/kg in a complete broiler diet. Feed intake, and body weight, were recorded then used to calculate feed conversion ratio. At the end of the experiment (42 days), four chickens from each pen were randomly selected for slaughter for carcass, bone morphology and sensory evaluation. Results: Results showed that onion extract supplementation did not affect (p>0.05) growth performances and meat sensory evaluation. However, there was a significantly increased (p<0.05) meat shear force in groups receiving onion extracts dietary treatments. Furthermore, onion extracts improved (p<0.05) bone morphology of broiler chickens in terms of weight, diameter, calcium, and phosphorous contents. Conclusion: In conclusion, onion extracts can be safely included in a commercial broiler diet as a growth promoter without causing adverse effects on growth performance traits and carcass quality in chickens. Onion extract supplementation improved tibia bone growth and strength in broiler chickens.
