Purpose: The aim of this study was to examine the effects of aroma hand massage on stress, fatigue, and sleep in sophomore nursing students. Methods: This study was a quasi-experimental design with a nonequivalent control group and a pre-post test was used. Thirty-seven sophomore nursing students were recruited. The experimental group (n=18) underwent 40 minutes aroma hand massage which was provided by the research assistant. The research assistant was trained with a video clip for aroma hand massage that was developed by Korea Aroma Association. Aroma oil contained lavender essential oil and sweet orange oil mixed with a jojoba oil base. The control group (n=19) did not receive any other treatments related aroma and massage. Results: Significant improvements were exhibited in scores for stress (t=-2.61, p=.013) and fatigue in the experimental group (t=-2.05, p=.047) compared to the control group. However, differences in sleep between two groups were not statistically significant (t=1.23, p=.277) between two groups. Conclusion: The results of this study suggest that aroma hand massage could be useful to decrease stress and fatigue levels for sophomore nursing students. Therefore, results of this study can be used as a basis of health care programs for reducing stress of nursing students.

The essential oil of Nardostachys jatamansi (Valerianaceae), which has been used for a long time in aroma therapy, was investigated after inhalation or oral administration for its analgesic effect, anticonvulsant action, hypnotic effect and in vitro inhibitory activity on monoamine oxidase. This fragrance oil showed a significant analgesic effect in the phenylquinone-induced .writhing test, suppressed the convulsion induced by pentylenetetrazole and lengthened the pentobarbital-induced sleeping time in a time-dependent manner after fragrance inhalation or dose-independently by oral administration. Its inhibitory activity on monoamine oxidase was remarkable, showing $49.4\%$ inhibition at a concentration of 5.0 mg/ml. Six new terpenes with seven known compounds were detected by our GC-MS analytical conditions used. As a result, the essential oil fragrance of Nardostachys jatamansi would be clinically useful for a sedative by either inhalation or oral administration.

This study examined the therapeutic effects of aromatherapy for the treatment of otitis externa in dogs. Eleven dogs with otitis externa were examined. The control group (5 dogs) was treated with susceptible antibiotics, and the experimental group (6 dogs) was treated with aroma-oil applied topically to the ear canal. The aroma-oil contained 10 ml sweet almond oil, 0.3 ml bergamot oil, 0.2 ml lavender oil, 0.1 ml tea tree oil and 0.1 ml roman chamomile oil. The blended aroma-oil (0.1 ml) was applied to the ear canal twice daily for 2 weeks. The authors examined the changes in the clinical signs, bacterial count in discharges, total WBC count and neutrophil/lymphocyte ratios in the two groups. The bacterial cell counts in the experimental group were significantly lower at one (p < 0.01) and two weeks (p < 0.05) after treatment than the control group. These results suggest that aromatherapy is an effective and practical treatment for otitis externa in dogs.
