Purpose : To investigate the effects of the lavender, lemon and eucalyptus oil mixture on the atopy dermatitis skin lesions induced on NC/Nga Mice by dinitrochlorobenzene (DNCB). Material and Method : For this purpose, we fabricated the oil mixture blending three essential oils (lavender, lemon, eucalyptus : ELL) with one carrier oil (jojoba) and apply it on the atopic dermatitis skin lesions of NC/Nga Mice. Atopic dermatitis in NC/Nga Mice was induced by DNCB treatment on the dorsal skin of mice for 8 weeks. The mixture of ratio of each essential oil drop was 1 (eucalyptus) : 2 (lemon) : 2 (lavender) and this mixture was blended with jojoba oil 50ml (0.025%). The ELL-ointment was supplied for 8 weeks. We evaluated the effects of ELL on cell viability of mouse lung fibroblast, clinical skin features and severity, the level of serum Immunoglobulin (Ig) E & Ig G1, Interleukin (IL)-4, IL-13 and Interferon (IFN)-$\gamma$. Results : ELL showed safety on the cell viability of mouse lung fibroblast compared with control group. The cell viability was measured by SRB method. The effects of ELL on clinical skin features and severity in DNCB-induced dermatitis model of NC/Nga mice was significant compared with control group. EEL also showed significant effects on clinical symptom score compared with control group. Serum IgE & IgG1 level and development of atopy dermatitis skin lesions were evaluated. Serum IgE & IgG1 production was significantly down-regulated in EEL group compared with control group. ELL also down-regulated the levels of IL-4 and IL-13, and up-regulated the level of IFN-$\gamma$ compared with control group significantly. Conclusion : ELL was effective on atopy dermatitis by modulating Th2 related factors.

This study was to suggest the method for wrinkle improvement using Mugil cephalus extract. In order to evaluate the cosmetic product made of M. cephalus extract, the experiments were conducted with subjects and skin states for 4 weeks. Effect of cosmetics containing M. cephalus extract on the water holding capacity and evaporation of the women skin were investigated. The water holding capacity was increased after 1 h of application. But after 2 h, it was decreased. In the case of the water evaporation, it was increased with the increase of time. On the clinical trial, it was also found that water, oil, and rough level on the women skin were increased and wrinkles were improved. Side effects were also not detected during the application and treatment of cosmetics. Based on this result, the application of M. cephalus extract had positive effects on the improvement of wrinkles and skin in women.

In this study we applied the NAG obtained by the deacetylation of chitin extracted from the shells of crabs and shrimp as cosmetic ingredient. In order to compare NAG with GLC we identified the influence of cytotoxicity, anti-inflammatory, melanin biosynthesis formation inhibition on skin cell, and we measured the effects of the change of melanin and red spots. The results show that there was not any attentive cytotoxicity on the Raw 264.7 cell and B16F10 cell, and NO formation anti-inflammatory hindrance effect induced from Raw 264.7 by LPS was slight, and NAG suppressed the increase of melanin generation concentration-dependently after we induced the melanin generation with ${\alpha}$-MSH on B16F10 and measured the melanin biosynthesis inhibition. From this result, we identified the applicability of the cosmetics containing NAG as functional cosmetic for enhancing skin-lightening because when cream containing NAG was applied to skin the index of melanin red spots showed statistically meaningful changes.

In this study, the backs with a hair cut of 6-week-old healthy ICR male mice were once exposed to a dose of $400\;mJ/cm^2$ UVB. An acute dermal inflammation was observed, and the certified 100% pure and natural lavender essential oil were applied to the UVB-exposed mice skin twice a day. It was observed that the mice exposed to UVB resulted in an acute inflammation, and when treated with lavender oil the degree of inflammation was much alleviated, and the inflamed skins of both the control and lavender oil-treatment groups were cured almost completely after 6 days of the UVB exposure. At 24 hours after UVB exposure, the epidermal keratinocytes in the control group showed a cell-membrane damage with the destruction of intercellular junctions, agglutination of tonofilaments within the cytoplasm and nucleus damage, while the lavender oil-treatment group had much less cell damage than the control group. While the control group showed a significant increase (p<0.05) in the activity of XO up to 144 hours, the lavender oil-treatment group did not show any significant increase except for 48 hours after the UVB exposure. Both the control and lavender essential oil-treatment groups had a significant decrease in the activities of CAT and SOD up to 96 hours. Particularly, the CAT activity was significantly lower(p<0.05) in the lavender oil-treatment group than the control group up to 48 hours, and higher than the control group at and after 96 hours. The GST activity was significantly decreased in both the control and lavender oil-treatment groups up to 96 hours after the UVB exposure except for the control group at 24 hours, and that of the lavender oil-treatment group was higher than the control group at and after 96 hours. Therefore, it is assumed that the application of the lavender oil to the ultraviolet-damaged mice skin can be effective in treatment for the damaged skin.

To evaluate the physiological significance of xanthine oxidase (XO) in rat skin, the activity of XO (type O) in skin was compared with that of small intestine or liver. Concomitantly, XO activities in some partial portions (scalp, leg, dorsal and ventral part) of skin were determined and then compared with each partial portion. XO activity of skin was lower than that of small intestine and rather higher than that of liver. Furthermore, the activity of XO in skin, after clipping of hairs and then in 5 days, was more increased than that of rat which was clipped before having been sacrificed. As for activities of free radical scavenging system (GPx, GST, SOD), skin is lower than liver and small intestine. Although it is hewn that the oxygen free radical generated by XO system lead to injurious effect on the cell, the XO activity of ventral part which is to be less exposed to xenobiotics and biological agents was the lowest among those of ventral, dorsal, leg and scalp parts in skin. In conclusion, it may be hypothesized that XO system in skin act on defence mechanism.

Wood vinegar is well known as a softening agent affecting on the stratum corneum that is easy to penetrate into the skin. In this study, we prepared mixed ursolic acid hydrogel with wood vinegar(1, 2, 5%) as a penetration enhancer. The accumulation of ursolic acid in the skin from hydrogels was evaluated in vitro hairless mouse skin and skin moisturizing effect of them was evaluated using the corneometer and the tewermeter. And the role of stratum corneum as a protective barrier was evaluated as well. The hydrogels were retained about 40% of water retention capacity 2hrs and had better effect on the stripped skin than full-thickness skin. The accumulation of ursolic acid through stripped skin from hydrogels with wood vinegar was not change compared to normal skin, which indicated the action site of wood vinegar and the accumulation site of ursolic acid would be stratum corneum. From these result, we could find wood vinegar seems to be a good enhancer for active materials with anti-wrinkle and anti aging effect such as ursolic acid, and can be a developed topical delivery system maintaining excellent water retention capacity.
