Objectives : The application of DNCB (1-chloro-2,4-dinitrochlorobenzene) can cause cellular immunity allergic reaction such as erythema or edema on NC/Nga mice and combinational function of cells participating in immunity increase inflammatory mediator. In this study, the effects of cypress essential oil on NC/Nga mice have been assessed. Methods : Male SPF NC/Nga mice aged 8 weeks have been used for atopic dermatitis induction skin. 1% DNCB was applied on ears and backs of which hair was removed using clipper on $1^{st}$ day and 0.4% DNCB was applied three times a week for 3 weeks. In this study, cypress essential oil has been treated 1 time a day for 3 weeks after application of DNCB to induce atopic dermatitis on skin for further experiments. Results : This study shows that inhalation or application of cypress essential oil reduced edema in ears and the thickness of epidermis induced by DNCB treatment. And it can be known that treatment of cypress essential oil inhibited mast cell proliferation and reduced IgE level similar to that of the negative control especially when cypress essential oil was inhaled by the mice. Synthetic oil showed the effects lower than those of cypress essential oil. Conclusions : Inhalation or direct application of cypress essential oil on skin reduced IgE level in blood and prohibits the proliferation of mast cell, from which it can be known that cypress essential oil can be effectively used to reduce the symptoms of atopic dermatitis.

수목에 스트레스를 가하여 정유를 증수할 목적으로 화학적 스트레스 자극제 5종과 생물적 스트레스 자극제 4종을 선발하여 실험을 실시하였다. 우선 정상적인 수목의 정유함량은 편백 2% 전후, 화백 1.6%, 소나무 0.4%, 잣나무 0.7%였으며, 상기 수종들은 모두 7월에 최대의 정유함량을 기록하였다. 또한 9종의 스트레스 자극제 처리 6개월 후 잎의 정유함량을 측정한 결과, 스트레스 자극제 처리에 의해 대체로 정류함량은 높아지는 경향을 보이고 있으나 자극제의 종류에 따라 변화가 없거나 또는 감소하는 경우도 있었다. 정유 증수효과에 영향을 미치는 수종별 최적 스트레스 자극제로 소나무는 치마버섯(SCC), 잣나무는 과산화수소수, 편백은 치마버섯(SCC), 화백은 ${\beta}-pyridone$이 선발되었으며, 특히 과산화수소와 ${\beta}-pyridone$은 공시한 4수종에 광범위하게 효과를 나타내는 스트레스 자극제였다. 그러나 뽕나무버섯(ARM)과 소나무잔나비버섯(FOP)의 잣나무 처리군 및 치마버섯(SCC)의 화백 처리군에서는 오히려 정유함량을 감소시켰다.

Objectives : Increasing evidence supports the biological and pharmacological activities of essential oils on the central nervous system such as pain, anxiety, attention, arousal, relaxation, sedation and learning and memory. The purpose of present work is to investigate the protective effect and molecular mechanism of cypress essential oil (CEO) against scopolamine (SCO)-induced cognitive impairments in C57BL/6 mice. Methods : A series of behavior tests such as Morris water maze, passive avoidance, and fear conditioning tests were conducted to monitor learning and memory functions. Immunoblotting and RT-PCR were also performed in the hippocampal tissue to determine the underlying mechanism of CEO. Results : SCO induced cognitive impairments as assessed by decreased step-through latency in passive avoidance test, relatively low freezing time in fear conditioning test, and increased time spent to find the hidden platform in Morris water maze test. Conversely, CEO inhalation significantly reversed the SCO-induced cognitive impairments in C57BL/6 mice comparable to control levels. To elucidate the molecular mechanisms of memory enhancing effect of CEO we have examined the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus. CEO effectively elevated the protein as well as mRNA expression of BDNF via activation of cAMP response element binding protein (CREB). Conclusions : Our findings suggest that CEO inhalation effectively restored the SCO-impaired cognitive functions in C56BL/6 mice. This learning and memory enhancing effect of CEO was partly mediated by up-regulation of BDNF via activation of CREB.

This study investigated the stimulative or sedative effects of inhaling fragrant essential oils (EOs) by using a forced swimming test (FST) with mice. This behavioral test is commonly used to measure the effects of antidepressant drugs. The inhalation by mice of EOs, such as ginger oil (p<0.05), thyme oil (p<0.05), peppermint oil (p<0.05), and cypress oil (p<0.01) resulted in 5% to 22% reduction of immobility. The same results were achieved when over-agitation was artificially induced in the mice by an intraperitoneal injection of caffeine (a psycho-stimulant). In contrast, inhalation of some EOs by the mice resulted in increased immobility. To evaluate more correctly the sedative effects of EOs, the immobility of over-agitated mice induced with caffeine was ascertained after the inhalation of various EOs. Inhalation of lavender oil (p<0.01) and hyssop oil (p<0.01) increased the immobile state in mice that were treated with caffeine. The results of this study indicate that the inhalation of essential oils may induce stimulative or sedative effects in mice.

Objective: In this study, we tried to investigate the antimicrobial activity of natural herbaceous plant-derived essential oils against oral disease-causing bacterial strains and establish the scientific evidences to apply them to the dentifrice, mouthwash, and other uses. Methods: We used the disk diffusion method with 23 types of 100% natural essential oils to verify the antimicrobial effect against Streptococcus mutans, Porphyromonas gingivalis, and Lactobacillus rhamnosus. After adhering to the surface of the plate culture medium, $20{\mu}l$ of the essential oil was prepared, and the diameter of the transparent ring was measured after incubation for 24 hours. All the experiments were repeated three times. Results: Among 23 types of oils, 13 were effective against all three strains: myrrh, ginger, basil, carrot seed, tea tree, patchouli, ylang ylang, cypress, lemongrass, cinnamon, peppermint, lavender, and eucalryptus. Seventeen oils were effective against S. mutans, and myrrh, basil, and carrot seed showed high antimicrobial activity. Eighteen oils were effective against P. gingivalis, and tea tree, carrot seed, and cinnamons showed high antimicrobial activity. Sixteen oils were effective against L. rhamnosus, and carrot seed and peppermint cinnamon showed high antimicrobial activity. Conclusion: Consequently, 13 essential oils showed the antimicrobial activity against three bacterial strains, which indicates these essential oils might be used as the effective materials to suppress the growth of oral-disease inducing microorganisms. Moreover, essential oils that have been analyzed activities in this study will be mixed up within the constant range and analyzed their antimicrobial effects to examine the synergistic activity among them.
