The summary of a study of efficacy of Rose essential oil and Lavender essential oil against skin-inflammation caused to surfactant is as follows. As a result of protein analysis, although Rose essential oil and Lavender essential oil stimulates skin, there is no much alteration of protein. The alteration of protein's bend to be under part of 43Kd is appeared in the group treated Rose essential oil and Lavender essential oil. The stratum of the group treated by surfactant is more, the stratum of the group treated by surfactant is more thick. As the observed result of alteration of basal layer, it is seen that the group treated Rose essential oil and Lavender essential oil takes the shape of cell layer constant, and the group treated Rose essential oil is made the basal cell layer of normal structure than that of Lavender essential oil. As the observed result of alteration of Mast cell group treated by Rose essential oil and Lavender essential oil for 3 weeks Luna's stain(${\times}20$), (${\times}100$), it is observed that the damaged group treated by Lavender essential oil is numerous in alteration of mast cell's number, and Mast cell's size is larger than the damaged group.

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.

This quasi-experimental study was to explore the effects of back massage with Lavender essence oil on the stress response of the ICU nurses. Method: Twenty nurses were selected as an experimental group and twenty nurses were in the control group. Lavender essence oil mixed with Jojova carrier oil was used to massage the neck, shoulder, back, and low back. Massage was done three times a week for 20 minutes for 2 weeks by the massage therapist. The stress response was measured with a subjective stress score, Cortisol and IgA level in saliva. The cortisol level in saliva was analyzed by an radioimmunoassay before and after back massage. The level of IgA in saliva was analyzed by an immunoturbidimeter assay and subjective stress scores was measured by Visual Analogue Scale. The data was analyzed using SPSS 8.0 and the hypotheses were tested by ANCOVA and the Pearson coefficient correlation. Result: 1) Score of subjective stress decreased significantly after the use of back massage with Lavender essence oil. 2) Level of Cortisol in saliva did not change significantly after the use of back massage with Lavender essence oil. 3) Level of IgA in saliva increased significantly after the use of back massage with Lavender essence oil. 4) After the use of back massage with Lavender essence oil, there was significant negative correlation between subjective stress and level of IgA in saliva. Conclusion: Back massage with Lavender essence oil is an effective intervention to reduce the stress response in the ICU nurses.

The summary of a study of efficacy of Rose essential oil and Lavender essential oil against physiologic active change s of skin caused to surfactant is as follows. 1. In feed intake efficiency, there is more significant difference than control group, and then in water intake, there are significant differences between each group. It is presented that the water intake efficiency ratio of the group treated by Rose essential oil and Lavender essential oil is higher than all of groups to be participated in experiment. And then, the reason that the group treated Lavender essential oil is lower than any other group is needed water intake to be caused by stress. 2. As the result of serum analysis, in atherosclerotic index(A.I), the cholesterol of control group is higher than that of the group treated. As HDL cholesterol is activated, the dan1aged group is higher than control group, in LDL cholesterol the control group is higher. It is seen that the damaged group of the quantity of HDL cholesterol is lower frequently in A.I. This fact is presented that HDL cholesterol that cholesterol is exhausted is changed, because of the dan1aged group that replacement is activated. 3. As the observed result of alteration of sebaceous glands, it is appeared that the demage of sebaceous glands is destroyed in the damaged group. It is observed that epidermis of the group applied by Rose essential oil after treated surfactant is dry, secretion of phenomenon of water and sebum is appeared more. It is observed that the epidermis recovery of the group applied by Lavender essential oil after treated surfactant is insufficient. And then it is seen that stratum corneum is recovered and the quantity of sebum secretion is decreased. 4. As the observed result of alteration of Mast cell group treated by Rose essential oil and Lavender essential oil for 3 weeks Luna's stain(${\times}100$), it is observed that the damaged group treated by Lavender essential oil is numerous in alteration of mast cell's number and Mast cell's size is larger than the dan1aged group. It is presented that the Mast cell's number and Mast cell's size is larger than the damaged group, the Mast cell's size and quantity of the group treated by Rose essential oil and Lavender essential oil is decreased more.

Objectives: The main objectives of this study were to verify the antibacterial activity of two essential oils, lavender and peppermint, against dental caries and to review their synergistic effect when used in combination. Our results provide basic data for the evaluation of the use of these two substances towards the prevention and cure of dental caries. Methods: The sample solutions of lavender and peppermint oils were prepared in three different concentrations (30%, 50%, and 70% (v/v)) by diluting them with third-distilled water and Tween 20. Streptococcus mutans was selected as the bacterial species for testing. The disk diffusion method was used to measure the antibacterial activity of the sample solutions. For generating growth curves and measuring the number of clusters of the bacterial, the liquid medium-dilution method was used; the absorbance of the medium was measured at 600 nm after 3, 6, 12 and 24 hours. Results: When the antibacterial activity of the oils was tested via the disk diffusion method, the activity improved with increasing concentrations of all the sample solutions of peppermint, lavender, and the blend, but there was no significant difference between them with respect to the type of oil. In the growth curves of S. mutans, growth inhibition was observed after 12 hours. The inhibitory effect of 30% lavender oil on growth was 64.9% and 80.1% after 12 and 24 hours of treatment, respectively whereas that of peppermint oil was 71.3% and 80.1% after 12 and 24 hours of treatment, respectively. The inhibitory effect of the blended oil was 71.9% and 81.0% after 12 and 24 hours of treatment, respectively. Conclusions: Further research is still required in order to determine the efficacy of lavender and peppermint oils, as well as other essential oils, for wider use in preventing dental caries.

Purpose: The purpose of this study was to evaluate the effects of essential oil on oxidative stress, immunity, and skin condition in atopic dermatitis (AD) induced mice. Methods: This study was a $3{\times}3$ factorial design. Factors were oil type (Lavender, Thyme, and 2:1 mixture of lavender and thyme oil [blending oil]) and treatment period (0 day, 7 days, and 21 days). The samples were 45 mice with AD and randomly assigned to nine groups of five mice per group. The dependent variables such as superoxide radical, IgE, degranulated mast cells, and epidermal thickness were measured. Data were collected from February to April in 2014. Descriptive statistics, One-way ANOVA, Two-way ANOVA, and Tukey's HSD test were performed using the SPSS WIN 20.0 program. Results: Dependent variables were not statistically significantly different by the three oil types (p >.05). Essential oils such as lavender, thyme, and blending oil were all effective in reducing AD symptoms and especially 2:1 blending oil were most effective. There were statistically significant differences by the three treatment periods in all dependent variables (p <.001). There were statistically significant interactions between oil types and treatment periods in all dependent variables (p <.01). For decreasing superoxide radical, degranulated mast cells, and epidermal thickness, 2:1 mixed oil should be applied for at least 21 days. Otherwise to reduce IgE, 2:1 mixed oil should be used for at least 7 days. Conclusion: These findings provide bases for developing effective interventions for AD patients to manage their AD symptoms.
