Objectives : BHH10 is traditional medicine herb used for enhancing body resistance against various diseases. The aim of this study was to identify BHH10 extract induces osteogenic activity in human osteoblast-like MC3T3-E1 cells. Methods : MC3T3-E1, pre-osteoblast cell line, were treated with BHH10 of various concentrations($0.1{\mu}g/mL$, $1{\mu}g/mL$, $10{\mu}g/mL$). And then, the effect of BHH10 on osteoblast differentiation was examined by alkaline phosphatase(ALP) activity, von Kossa staining and RT-PCR for osteoblast differentiation markers such as osteocalcin(OCN), osteopontin(OPN). Results : BHH10 had dose-dependent effect on the viability of osteoblastic cells, and dose-dependently increased alkaline phosphatase(ALP) activity. BHH10 markedly increased mRNA expression for OCN, OPN in MC3T3-E1 cells. Also, BHH10 significantly induced mineralization in the culture of MC3T3-E1 cells. Conclusions : In conclusion, these results propose that BHH10 can play an important role in osteoblastic bone formation, osteogenesis, and may possibly lead to the development of bone-forming drugs.

Objectives : The purpose of this study is to investigate the effects of Chowiseungcheng-tang extracts on the preadipocytes proliferation in 3T3-L1 cell line, lipolysis of adipocytes in rat's epididymal adipocytes and localized fat accumulation of porcine by extraction methods(alcohol and water). Methods : Diminish preadipocytes proliferation and promote lipolysis of adipocytes do primary role to reduce obesity. So, we used 3T3-L1 mouse embryo fibroblasts(preadipocytes) and rat epididymal adipocytes from Sprague-Dawley rats to investigate the effects of Chowiseungcheng-tang extracts on the preadipocytes proliferation, lipolysis of adipocytes. They were treated with 0.01, 0.1, $1.0mg/m{\ell}$ Chowiseungcheng-tang alcohol and water extracts. And for the purpose of investigating the effects of Chowiseungcheng-tang alcohol and water extracts on the localized fat accumulation, we injected 0.1, 1.0, $10.0mg/m{\ell}$ Chowiseungcheng-tang extracts to porcine fat tissues and observed histological changes of them. Results : Following results were obtained from the preadipocytes proliferation and lipolysis of adipocytes and histological investigation of fat tissues. 1. Chowiseungcheng-tang extracts suppressed preadipocytes proliferation on the high dosage(especially $1.0mg/m{\ell}$), and especially alcohol extracts had better effects. 2. The alcohol extracts of Chowiseungcheng-tang decreased the activity of glycerol-3-phosphate dehydrogenase (GPDH) on the concentrations of 0.1, $1.0mg/m{\ell}$. Alcohol extracts had better effects than water extracts. 3. Chowiseungcheng-tang extracts increased lipolysis of adipocytes on the concentrations of 0.1, $1.0mg/m{\ell}$, and especially on the concentration of $1.0mg/m{\ell}$ alcohol extract of Chowiseungcheng-tang had better effect. 4. The water extract of Chowiseungcheng-tang had significant activity to the destruction of porcine fat cell membranes only on the concentration of $10.0mg/m{\ell}$, but alcohol extracts of Chowiseungcheng-tang had it on all concentrations. Conclusions : The alcohol extracts of Chowiseungcheng-tang had much better effects on the preadipoeytes proliferaton, lipolysis of adipocytes and localized fat accumulation than water extracts.

As a preliminary study for the development of cancer-preventing functional food using Korean mistletoe, the cytotoxic effects of Korean mistletoe on between non-tumorigenic A3l cell and tumorigenic MSV cell derived from mouse 3T3 fibroblast cell line were investigated. While the raw extract, of which $ID_{50}$, value was $3.94\;{\mu}g/mL$, showed strong cytotoxic effect, its heat-treated extract was not cytotoxic up to $30\;{\mu}g/mL$. On the other hand, the heat-treated extract with law concentration showed an accelerative effect on the proliferation of non-tumorigenic A3l cell and an inhibitory effect on that of tumorigenic MSV cell. In addition, the influences of the addition of carbohydrates, such as galactose, lactose, glucose, mannose, fructose, sucrose and starch, to mistletoe extract were studied. There were not any significant changes with raw extract plus carbohydrate treatment, but the accelerative and inhibitory effects of heat-treated extract on each A3l and MSV cell were increased further by the treatment with sugars such as lactose, galactose, glucose, fructose. In order to investigate the changes of cytotoxicity of fermented Korean mistletoe according to fermentation periods, the raw and heat-treated extract were inoculated with Lactobacillus plantarum. During 1, 3, 5 and 7 fermentation days, the fermented raw mistletoe extract showed gradual accelerative effect on A31 cell proliferation without any changes of cytotoxicity on MSV cell. In case of the fermented heat-treated extract, however, the accelerative effect of heat-treated extract on A31 cell proliferation in early stage was disappeared during the fermentation.

Colostrum basic proteins (CBP) (MW 1$\sim$30 kDa) were isolated from bovine colostrum using a series of ultrafiltration processes and their effects on osteoblast cell proliferation and bone metabolism were investigated in cell line and animal models. Treatments with CBP (1, 10, 100 $\mu$g/mL) dose-dependently increased cell proliferation of osteoblastic MC3T3 cells. Alkaline phosphatase activity, a marker of osteoblastic phenotype, in the cells was also increased after treatments with CBP in a dose-dependent manner. Significant increases in bone density were observed in femur of ovariectomized rats which were fed a diet with 1% and 10% CBP, compared to rats fed a normal diet. These results suggest that CBP may increase bone mass and density and be useful for the prevention of bone-related diseases.

Ginseng root explants and calli induced from selected cell lines were cultured on modified Murashige and Skoog's media supplemented with different concentrations of organic or inorganic compounds and plant growth requlators to clarify the effects of chemical composition and plant growth regulators in the medium on the growth of ginseng calli and the production of ginseng saponin. For optimum growth of calli, the concentrations of 2, 4-D and sucrose were the range of 1 to 3 mg/${\ell}$l and 1 to $3\%,$ respectively. And it was clarified that sucrose, nitrogen, phosphate, calcium, magmesian plant growth regulators and their concentrations influcenced the relative biosynthesis of saponin in tissue cultures of Panax ginseng. The patterns of ginsenosides, pharmacologically useful component, were different among the cell lines and contents of ginsenosides were much higher in selected cell lines than in original cell line.

The Strain TFM-7, Which has an antitumor effect, was isolated from Kefir and identified based on analysis using the API 50 CHL kit and 265 rDNA sequencing. Strain TFM-7 was confirmed to belong to the genus Kluyveromyces. Analysis of the 265 rDNA nucleotide sequences found strain TFM-7 to be related to Kluyveromyces marxianus. NRRL Y-828IT. K. marxianus. TFM-7 was cultured with potato dektrose broth medium at $27^{\circ}C$ for 72 hr, and its inhibition effects on the proliferation of seven tumor cell lines and a normal cell line were assessed using the MTT assay. The antitumor effects and growth characteristics of K. marxianus TFM-7 were investigated during a culture period of 7 days. By the $3^{rd}\;day$, K. marxianus TFM-7 showed a dry cell weight 2.39 g/L, a pH of 4.39, an ethanol content of 0.89%, and an inhibition effect on the proliferation of seven tumor cell lines above 50%, except for A-549 tumor cell line. K. marxianus TFM-7 was the most effective at inhibiting the growth of Hep-2 cell line among all tumor cell lines tested. Growth inhibition of a normal cell line, NIH/3T3, was less than 35%, suggesting a decreased level of cytotoxicity toward normal cells. These results indicate that K. marxianus TFM-7 may have used as a yeast strain with antitumor activity.

Obesity is associated with an increased risk of many diseases including type 2 diabetes mellitus, hypertension, and hyperlipidemia. The flowers of Chrysanthemum boreale have been used as traditional medicines for the treatment of diseases such as obesity and type 2 diabetes mellitus. This study aimed to evaluate the effect of C. boreale Makino flower essential oil (CFEO) on adipocyte differentiation using preadipocyte cell line 3T3-L1. CFEO at concentrations between 0.1 and $5{\mu}g/ml$ did not affect 3T3-L1 cell viability. A CFEO concentration of between 0.1 and $1{\mu}g/ml$ significantly inhibited lipid accumulation during MDI-induced differentiation in 3T3-L1 cells in a dose-dependent manner, reaching a maximal level at $1{\mu}g/ml$ ($28.94{\pm}2.01%$; approximately 30% of control treated with MDI alone). Western blot analysis revealed that CFEO concentrations between 0.1 and $1{\mu}g/ml$ suppressed the activations of three adipogenic transcription factors in the MDI-stimulated 3T3-L1 cells: peroxisome proliferator-activated receptor ${\gamma}$; CCATT/enhancer binding protein ${\alpha}$; and sterol regulatory element binding protein-1. Moreover, the expressions of lipogenic enzymes, acetyl-CoA carboxylase, and fatty acid synthase were also inhibited by treatment with CFEO between 0.1 and $1{\mu}g/ml$. CFEO may therefore be a promising functional material for obesity prevention.
