This study was conducted to examine the effects of eggshell membrane hydrolysates (ESMH) on the anti-inflammatory, anti-wrinkle, anti-microbial activity, and moisture-protection for cosmetic use. Whole ESMH (before fractionation), and fraction I (>10 kDa), fraction II (3-10 kDa), and fraction III (<3 kDa) of the hydrolysates were assessed in this experiment. As lipopolysaccharide (LPS) and IFN-${\gamma}$ caused the inflammation on Raw264.7 cell, whole ESMH and fraction I showed to be effective in inhibiting the induction of cell inflammation depending on the concentration, and also showed outstanding effect to suppress the skin inflammation. Fraction I inhibited collagenase and elastase activities to a greater extent than the other fractions, while all fractions had antibiotic effects at concentrations of 10 mg/disc and 20 mg/disc. In addition, it showed the moisture protection effects of skin on the holding amount and losing amount of moisture in upper-inner arm of the human body with a relatively low loss rate in skin, which confirmed that the hydrolyzed fractions of ESM helps to form the superior protective layer of moisture. It was concluded that ESMH fractions with different molecular weights, especially the 10 kDa fraction, have anti-lipopolysaccharide, anti-IFN-${\gamma}$-induced inflammation, anti-collagenase and elastase activities, and thus can be used as a cosmetic agent to protect skin.

Carnosol is a phenolic diterpene phytochemical found in rosemary and sage with reported anti-microbial, anti-oxidant, anti-inflammatory, and anti-carcinogenic activities. This study aimed to investigate the effect of carnosol on the lineage commitment of mouse bone marrow-derived mesenchymal stem cells (mBMSCs) into osteoblasts and adipocytes. Interestingly, carnosol stimulated the early commitment of mBMSCs into osteoblasts in dose-dependent manner as demonstrated by increased levels of alkaline phosphatase activity and Alizarin red staining for matrix mineralization. On the other hand, carnosol significantly suppressed adipogenesis of mBMSCs and downregulated both early and late markers of adipogenesis. Carnosol showed to induce osteogenesis in a mechanism mediated by activating BMP signaling pathway and subsequently upregulating the expression of BMPs downstream osteogenic target genes. In this context, treatment of mBMSCs with LDN-193189, BMPR1 selective inhibitor showed to abolish the stimulatory effect of carnosol on BMP2-induced osteogenesis. In conclusion, our data identified carnosol as a novel osteoanabolic phytochemical that can promote the differentiation of mBMSCs into osteoblasts versus adipocytes by activating BMP-signaling.

To evaluate the possibility as a natural preservative of Cornus officinalis seed extracts, we investigated the anti-microbial activity and preservation effect of cosmetics. Cornus officinalis seed extracted with 1,3-Butylene Glycol(1,3-BG) and Ethanol(EtOH). As a result, Cornus officinalis seed extracts showed anti-microbial activity at Staphylococcus aureus, Staphylococcus epidermidis, Propionibacterium acnes and Cornus officinalis seed 1,3-BG extracts(COS-A) showed $26.7{\pm}4.0mm$ clear zone at the $1000.0{\mu}l/ml$. Minimum inhibitory concentration of S. epidermidis was observed at Cornus officinalis seed EtOH extracts(COS-B) $25.0{\mu}l/ml$. The result of challenge test for preservation effect on cosmetics, S. aureus and S. epidermidis was 100% eliminated from emulsion containing COS-A and COS-B after 7 days. These results suggest that Cornus officinalis seed extracts may have possibility as the natural preservative instead of synthetic perservative on cosmetics.

To screen the effective materials for hair loss treatment, several natural extracts were tested using in vivo and in vitro test models. Firstly, all test materials were applicated onto the back skin of C57BL／6 mouse and then hair growth promoting effect was measured using hair growth index. As a result, Prunus mume, black bean, Brassica campestris subsp. black sesame and Rubi Fructus showed potent hair growth promoting effect, ranking as 1.5-2.0 of hair growth index. However, there were no plant extracts, which have remarkable potential of growth promotion of human hair dermal papilla cells cultured in vitro. In the experiments of 5${\alpha}$-reductase type Ⅱ inhibition assay, Prunus mume, Eriobotryae Folium showed effective potential to inhibit the activity of 5${\alpha}$-reductase type Ⅱ. To investigate the possible involvement of the effect of several plant extracts on the gene expression of growth factors in human hair dermal papilla cells, RT - PCR analyses were performed. However, there were no plant extracts, which have profound effect on the gene expression of several growth factors such as IGF-I, KGF, HGF and VEGF in the dermal papilla cells. Another tests for inhibition of microbial such as P. acne were also carried out to find whether these plant extracts have anti -microbial activities. Rubi Fructus showed anti -microbial effects on Propionibacterium acnes, which is believed as a pathogen of acne. Together, these results showed several plant extracts can be used for hair growth promotion.

The immune system is not fully developed in human neonates and infants; breastfeeding is important in this stage as the bioactive components of human breast milk are known to have anti-microbial, anti-inflammatory, and immunomodulatory effects, and can therefore contribute to an infant's immunity against allergies, asthma, autoimmune diseases, and inflammatory bowel disease. Herein, the positive effect on the immune system by human colostrum and milk are reviewed.

When the symptom of periapical infection is not released by mechanical instrumentation. anti-microbial agents including antibiosis become necessary in order to remove microorganisms from the root canal. Since anti-microbial agents of natural origins are currently popular, more natural remedies are being sought out. As it turns out, it is well known isothiocyanates (ITCs) in horseradish root extract have anti-microbial activity from many studies. In this research, anti-microbial effects of horseradish root extract and chlorhexidine, a typical anti-microbial agent, were investigated and compared against two kinds of obligate anaerobes. Fusobacterium nucleatum and Prevotella nigrescens, that are often discovered in infected root canal, and Clostridium perfringens, which is resistant to antibiotics and frequently used as a control strain for antibacterial studies 1. The MIC and MBC of horseradish root extract were ranged from 87 to 470 ppm and from 156 to 625 ppm against three kinds of obligate anaerobes, respectively. Horseradish root extract showed the strongest anti-bacterial activity (MBC, 156 ppm) against F. nucleatum and also showed anti-bacterial activity against antibiotic resistant obligate anaerobes. C. perfringens. 2. The MIC and MBC of chlorhexidine were ranged from 3.12 to 6.25 ppm and 10.94 ppm against three kinds of obligate anaerobes, respectively. 3. The MIC with 87-470 ppm of horseradish root exact has the same growth inhibiting effect as the one of 3.12-6.25 ppm of chlorhexidine. Likewise, the MBC with 156-625 ppm of horseradish has the similar bactericidal effect as 10.94 ppm of chlorhexidine.

Herbal mixture water extract of (Chrysanthemum morifolium, Portulaca oleracea, Sanguisorba officinalis, Sophora flavescens, Phellodendron amurense, Cnidium monnieri) which exhibit several beneficial effects including acne and skin diseases, was tested for anti-microbial activity and anti-inflammation effects. The herbal mixture extract showed antimicrobial activity against Stapylococcus epidermis, and Propionibacterium acne. The growth of Stapylococcus epidermis, and Propionibacterium acne was inhibited completely by addition of 1.0% of the extract. Also in the present study we examined the mixture extract on compound 48/80 induced allergy and LPS induced cyclooxygenase-2(COX-2) gene expression in RAW 264.7 macrophage. The results indicated the ear swelling and histamine release induced by compound 48/80 were dose-dependently reduced, ranging 28-60%, and 48-72% , respectively. Furthermore the extract inhibited the expression of LPS-induced COX-2 proteins and mRNAs without an appreciable cytotoxic effects on RAW 264.7 cells. The LPS-induced cytokine gene expression including IL-$1{\beta}$, TNF-$\alpha$, and IL-6 were dose-dependently suppressed by the mixture extract. Based on these results, it is concluded that the herbal mixture water extract can be applied to the acne and skin diseases therapy.
