Objectives: Literature has shown that micro-organisms contaminate gutta percha (GP) during storage and manipulation. Till date herbal extracts are not explored as an alternative medicament for pre-operative chairside disinfection of GP cones. The purpose of our study was to evaluate the antimicrobial activity and efficacy of lemon grass oil (LG), basil oil (BO), and obicure tea extract (OT) in disinfecting GP cones before obturation. Materials and Methods: Agar diffusion method was used to evaluate the antimicrobial efficacy of LG, BO, OT, and sodium hypochlorite (control) against common contaminants, namely, Enterococcus faecalis, Staphylococcus aureus, and Candida albicans. One hundred and twenty GP cones were contaminated and cut into 2. First half was placed in the broth and incubated; whereas the second was treated with herbal extracts for 1 minute and then incubated for 24 hours in the broth. Any inhibition in bacterial growth was noted with presence/absence of turbidity. Two-way analysis of variance and ${\chi}^2$ test were used to assess the effectiveness of herbal extracts to decontaminate GP. Results: LG showed the highest inhibition zones ($29.9{\pm}6.9mm$) for all tested organisms, followed by OT extract ($16.3{\pm}1.8mm$), sodium hypochlorite ($16.0{\pm}1.6mm$), and BO ($14.5{\pm}5.3mm$). Statistically significant difference was observed between LG and other herbal extracts (p < 0.05). Conclusions: All extracts proved to be potential rapid chairside disinfectants of GP cones with LG showing the highest antimicrobial activity.

This study is performed to investigate the effects of citrus essential oils on melanin production in B16 melanoma cells. Five kinds of citrus essential oils (Bergamot, Grapefruit, Lemon, Mandarin, Petigrain) did not have any influence on DPPH radical scavenger activity, cell growth and cytotoxicity in B16 melanoma cells. Both mandarin and petigrain essential oils dose-dependently inhibited purified tyrosinase activity, but bergamot did not. In 1$\mu$M MSH-stimulated B16 melanoma cells, all of 5 citrus essential oils inhibited melanin production in a dose dependent manner. From the above results, it is possible that citrus essential oils may be developed to be an anti-melanogenesis agent on the basis of their inhibitory effect on MSH-induced melanin production.

This study was conducted to investigate the effect on Brain Quotient from inhalation of blended oils. The subjects of the study were 64 people aged 20 to 59 years, with 32 in the experimental group and 32 in the control group. Blended oil with six aromas (Lavender, Bergamot, Mandarin, Lemon, Cedarwood, Roman Chamomile) was given to the experimental group, and Jojoba oil was given to the control group, for 30 minutes. Before and after the experiment, BQ tests (SRQ, BRQ, ATQ, ACQ, EQ, ASQ, CQ, and BQ) from the experimental group and the control group were compared and analyzed using a brain-training machine (NeuroHarmony S). There was a significant difference between the experimental group and the control group in three out of the eight tests analyzed ATQ (p<.05), ACQ (p<.05), BQ (p<.05). In other words, aromatherapy improves concentration and memory by increasing attention, and helps to maintain mental activity, thinking ability, and behavioral balance. BQ also represents a comprehensive brain function, and aromatherapy is a good way to maintain human mental and physical health.

Purpose: This study was aimed to evaluate the effect of blending oils on atopic dermatitis (AD) model of NC/Nga mice. Methods: Adult NC/Nga mice were assigned to 1 of 3 groups: control group (C, n=8), experimental group [AD-induced group, blending oil-treated group (E=8, 8)]. Mice in the E group were given a treatment of blending oils such as Lavender, Rosemary and Lemon Balm (LRL) for 2 sessions (every day) for 6 days. Results: The AD-induced mice with LRL blending oils treatment showed a significant decrease in epidermal thickness, number of mast cells and degranulation, expression of TNF-${\alpha}$ and scoring of sensual assessment. Conclusion: LRL blending oils may be a putative resource for the cure of or treatment of AD by the diminution of AD-pathological factors such as the epidermal thickness, the number of mast cells and degranulation as well as the expression of TNF-${\alpha}$.

In the present study, the correlation between subjective assessment and EEG for essential odors were investigated quantitatively. EEG signals were measured from 19 electrodes according to the International 10-20 system (Fp1, Fp2, F3/4, F7/8, Fz, C3/4, Cz, P3/4, Pz, T3/4, T5/6, O1/2) from 8 healthy males subjects for four odor(Rose oil bulgarian, Lemon oil misitano, jasmin abs, Laverder oil france (KIMEX co. Ltd) conditions. The result of the subjective assessment shows the most pleasant odor for each subject. and the power spectrum of ${\alpha}/({\alpha}+{\beta})$ of EEG signals from the most pleasant odor was compared with those from the control condition, which has no odor at all. Power spectrum of ${\alpha}/({\alpha}+{\beta})$ of EEG from the most pleasant odor was increased significantly at T4, T6 compared to the control condition. This result implies that the parameter, power spectrum of ${\alpha}/({\alpha}+{\beta})$, could be an important index for signifying the levels of pleasantness for odors.

본 연구는 쾌하고 안정의 감성을 유발하는 향과 상대적으로 쾌도가 작고 각성의 감성을 유발하는 향이 스트레스 자극 후에 안정 상태로의 회복에 미치는 영향을 관찰하고자 하였다. 사용된 향은 100%의 Rose oil bulgarian, Lemon oil misitano, Jasmin abs., Lavender oil france (KIMEX co. Ltd)의 네 가지이고 자율신경계의 반응은 심전도, 피부저항의 생리신호로 측정하였다. 스트레스의 유발은 단계적으로 난이도를 증가시키면서 덧셈의 연산 결과가 옳은지 틀린지를 검증하게 하였다. 실험과정은 처음의 안정 상태를 3분간 측정하였고, 2분의 계산 부하가 주어졌고 다시 3분간의 회복 상태를 측정하였다. 3분간의 회복 과정 측정 시 향을 제시하지 않은 상태를 통제 집단으로 하여 각각의 향을 제시했을 때의 상태와 비교하였다. 주관적 평가에서 상대적으로 레몬과 라벤더 향은 긍정과 이완 감성을, 자스민과 장미는 부정과 긴장 감성을 유발하는 향이라고 피험자들은 대답하였고 이것은 생리신호의 분석결과 스트레스 자극 유발 후 안정상태로의 회복이 향을 제시하지 않은 상태와 비교해서 레몬과 라벤더 향을 제시했을 때 빨라지고, 장미향을 제시했을 때 느려진다는 사실과 어느 정도 일치한다. 그러므로 비록 예비 실험이기는 하지만 본 연구에서는 스트레스에 의해 유발된 교감신경계 활성화의 회복을 촉진시키거나 또는 더디게 하는 향의 심리적 효과를 자율신경계의 반응으로서 검증할 수 있었다.

To enhance the control efficacy against cockroaches in dwelling space, repellent ("Push") was set down on one comer and a poison bait including attractant ("Pull") was on the opposite side. And we tested the control efficacy of Push-Pull strategy by behavior-stimuli of cockroaches. In a mini-field test, German cockroach males primarily chose shelters nearest to the attractant-treated surfaces and farthest from the repellent-treated surfaces. The consumption of food or bait was also highest from food nearest to the preferred shelters by push-pull effect. We evaluated the push-pull insecticidal efficacies of five essential oils belong to Citrus plant, namely, grapefruit, lemon, lime, orange, and petitgrain. The combined push-pull treatments appeared to be faster and higher insecticidal effects than single (pull) treatment, and the repellent efficacy of Citrus oils was in the order of grapefruit > lemon > lime > orange > petitgrain. Therefore, we propose the effective control of the german cockroach using Citrus oils as repellents and push-pull method into a limited area.
