The purpose of this study was to explore the psychoneuroimmunologic effect of aromatherapy massage and to compare the effect with that of massage. This study is designed as a nonequivalent control group pretest-posttest quasi-experimental study and each twenty postpartum mothers volunteered the experimental group and control group. For experimental group, researcher used massage with 2% Jojova oil mixed with Lavender and Rosemary oil (Bush Boake Allen Inc., USA) for 20 minutes, whereas for control group Jojova oil was used as luburicant for massage. Skin temperature was measured with YSI Tele-thermometer(Simpson electric Co., USA) and the concentration of IgA in salivary was analyzed by immunoturbididimetric assay(Cobas INTEGRA, Roche, Swiss) at pre and post test. Also at this time fatigue were measured by Rhoten Fatigue Scale through self-report. The data were analyzed using SAS and hypothesis was tested with unpaired t-test. The results were as follows : 1) Score of fatigue decreased significantly after use of aromatherapy massage. 2) Skin temperature increased significantly after use of aromatherapy massage. 3) Concentration of salivary IgA increased significantly after use of aromatherapy massage. In conclusion, from the standpoint of psychoneuroimmunologic view, the results suggest that aromatherapy massage have greater effect compared with massage and can be effective nursing intervention to enhance relaxation of mind and body in the postpartum mothers.

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.

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.

Citrus essential oil were extracted from citron peel of cultivated in Gohong (CCP) using environmentally friendly supercritical carbon dioxide method. Antioxidant activity and aroma composition of the essential oils extracted by the SC-$CO_2$ method were evaluated by comparing with those extracted by organic solvent method. Fatty acid composition, DPPH scavenging, and antioxidant activity of the oils obtained by different extraction condition of SC-$CO_2$ method were investigated and their antioxidant activities were compared with commercially available lavender, eucalyptus and tea tree oils. As the results, linoleic acid was most abundantly found from CCP oil extracted by the SC-$CO_2$ method and cis-11,144-eicosadienoic acids was second abundantly found. Radical scavenging ability of DPPH was 98% when the concentration of CCP oil was 50 mg/mL. This scavenging ability increased with the increase of oil concentration. On the other hand, flavonoids content (84 mg/100g) of the CCP oil extracted by the SC-$CO_2$ method was slightly higher than that (75 mg/100g) by hexane extraction. The results, obtained from CCP oil by GC-MS, indicated that, among 66 components, the content of terpenes was 55.8% and limonene was 27.3%.

Purpose: This study was an experimental study to compare the inhalation effects of aroma essential oil on the quality of sleep (QOS) for shift nurses after working nights. Methods: The participants were 60 healthy adults who didn't have any disease. As an experimental treatment, the participants in the experimental group were asked to inhale essential oil for 3 minutes at a distance of approximately 10 cm from their nose and then they were asked to sleep with the aroma stone beside their head (within a 30 cm distance). QOS were measured four times on Pretest, Day 1, Day 2, and Day 3 after they slept. To measure QOS, Perceived QOS (Numeric Rating Scale), the Verran & Synder-Halpern (VSH) Sleep Scale were used, and number of awakenings (NoA) was measured by Actigraph. Results: There were no significant differences in the homogeneity tests for general characteristics and dependent variables prior to the experiments, except for VSH of subjective sleep quality. Also, there was no significant interaction between group and time. The VSH of the experimental group was higher than the control group (F=6.39, p=.002). The NoA between the experimental group and the control group was significantly different after experimental treatment 3rd day (F=13.35, p=.001). Conclusion: The findings show that the inhalation of aroma essential oil had effects to increase the quality of sleep. Therefore, the inhalation of aroma essential oil could be applied to general nursing interventions to improve the quality of sleep.

This study was conducted to investigate the effect of aromatherapy on the autonomic nervous system by the inhalation. The subjects of the study were 64 people aged 20 and under 59 years old, 32 in the experimental group and 32 in the control group. Blending oil with Six aroma(Lavender, Bergamot, Mandarin, Lemon, Cedarwood, Roman Chamomile) was applied to the experimental group, and Jojoba oil was applied to the control group for 30min. Before and after the experiment, HRV(TP, VLF, LF, HF, LF/HF) of the experimental group and the control group were compared and analyzed using pulse wave mesuring instrument(uBioClip v70). There was a significant difference between the experimental group and the control group in 3 out of 5 items analyzed TP(p<.05), LF(p<.05), HF(p<.01). In other words, aromatherapy increases the total activity of the autonomic nervous system by enhancing the TP, increases the activity of the sympathetic and parasympathetic nerves, promotes the activity of the heart, Facilitate the activity of the heart. Therefore, if aromatherapy is used steadily in everyday life, it will enable healthy life by positively affecting the autonomic nervous system response.

Purpose: The purpose of this study was to investigate the effect of aromatherapy on pain, depression, and feelings of satisfaction in life of arthritis patients. Method: This study used a quasi-experimental design with a non-equivalent control group, pre-and post-test. The sample consisted of 40 patients, enrolled in the Rheumatics Center, Kangnam St. Mary's Hospital, South Korea. The essential oils used were lavender, marjoram, eucalyptus, rosemary, and peppermint blended in proportions of 2:1:2:1:1. They were mixed with a carrier oil composed of almond (45%), apricot(45%), and jojoba oil(10%) and they were diluted to 1.5% after blending. The data were analyzed using an 2-test, Fisher's exact test, t-test and paired t-test. Result: Aromatherapy significantly decreased both the pain score and the depression score of the experimental group compared with the control group. However, aromatherapy didn't increase the feeling of satisfaction in life of the experimental group compared with the control group. Conclusion: The result of this study clearly shows that aromatherapy has major effects on decreasing pain and depression levels. Based on our experiment's findings, we suggest that aromatherapy can be a useful nursing intervention for arthritis patients.

Purpose: The purpose of this study is to determine effects of aromatherapy on the activity and balance of autonomic nervous system and on physical resistance to stress. Methods: This research is a primitive experimental design which attempts to analyze aromatherapy EKG monitoring on real-time basis. Lavender & Chamomile, each 30 drops, were blended with 100ml Sweet Almond oil. Subjects was laid relaxed, and had insides of his wrists and ankles attached with electrodes for EKG. Right after applied with essential oil onto his philtrum and parotid, started on EKG monitoring. Results: The activities of parasympathetic and sympathetic nerve were changed as time elapsed, with significant differences(p=.000). In multiple comparison, the value was significantly different(p<.05).The balance of autonomic nerve was changed, becoming close to the normal level in accord with applicable international standards(1.5)(p=.011). In multiple comparison, the value showed a significant difference(p<.05). Physical resistance to stress increased with the passage of time, but not statistically significant. Conclusions: This suggests that aromatherapy can be used as a nursing intervention which aims at alleviating symptoms related to the imbalance of autonomic nerve system such as headache, hot flashes, irregular heartbeat, nervousness, depression and anxiety.
