Purpose: Aroma therapy is one modality of alternative medicine. It was well known to have an analgesic, antidepressive and anxiolytic effects. This study is designed to investigate the effect of aroma self hand massage on vital signs, pain, depression, anxiety and stress in breast cancer patients. Methods: 32 female patient over 20 years old were divided into two groups by a non-blinded randomized controlled method. Patient in the aroma group (n=15) massaged their hands twice a day using aroma oil by themselves in their home for 2 weeks. However, those in control group (n=17) had not received my intervention during the study periods. Pain intensity, state anxiety, depression and stress of subjects were evaluated three times (0, 1, 3 weeks) using Visual Analogue Scale (VAS, $0{\sim}10cm$), State Trait Anxiety Inventory (STAI), Beck Depression Inventory Scales (BDIS), Brief Encounter Psychosocial Instrument (BEPSI revised edition). Also the change of patients' accompanying symptoms after aroma massage were analyzed using a structured questionnaire. Results: Pain Intensity decreased in the aroma group compared with control group (VAS changes $-0.83{\pm}1.01\;vs\;0.38{\pm}0.86$, P=0.005). The numbers of accompanying symptoms (P=0.044), depression score (P=0.001) and anxiety score (P=0.008) were significantly decreased in the aroma group, while in control group they increased after 2 weeks. However, the stress score showed no significant changes in both groups ($0.05{\pm}0.85\;vs\;0.04{\pm}0.20$, P=0.1519). The depression, anxiety and stress score showed negative correlation with compliance of aroma massage, but statistically no significant. The systolic blood pressure was a little increased in aroma group ($4.53{\pm}14.43\;vs\;0.0{\pm}7.22$, P=0.026), but was not significant clinically. Patients in the aroma group complained of several symptoms such as headache (20%), paresthesia (6.75%) and nausea (6.7%). However, there were no drop-out patients for those side effects. Conclusion: Aroma self massage during two weeks in breast cancer patients alleviates the pain intensity, depression and anxiety significantly.

Previous studies have been conducted on domestic materials as a single extract. Research on complex mixtures for maximizing plant characteristics by individual extraction and potential interference with effects is insufficient. Therefore, this study confirmed the GC-MSD according to the extraction of essential oils for Agastache rugosa O. Kuntze(AR), Pinus densiflora Sieb. et Zuccarini(PD), Curcuma longa, Curcuma domestica(CC), Zingiber officinale Roscoe(ZR), Foeniculum vulgare Miller(FV), and Citrus medica L. var. sarcodactylis Swingle(CS). The cytotoxicity, antioxidant, and anti-inflammatory properties of the blending oil were confirmed to confirm its potential as a cosmetic material. As a result of analyzing GC-MSD aroma components, the main components were estragole of AR, à-Pinene for PD, Zingiberene for CC and ZR, Anethole from FV, and D-Limonene for CS. At a concentration of 100 uL/mL with no confirmed cytotoxicity, NO production was inhibited by 70.62%, DPPH radical scavenging activity was 64.03%, and ABTS radical scavenging activity was 89.55%. Through this, blended essential oil suggests the possibility of useful application as a raw material with antioxidant and anti-inflammatory effects in the cosmetic and food industries.

Sesame seeds were roasted for 30, 60, 90, and 120 min at different temperatures (100, 200, and $300^{\circ}C$) and extracted to investigate an adequate condition for producing the high quality sesame oil. Sesame seeds roasted at $200^{\circ}C$ for 90 min gave the high yield of oil. The oil contained the low content of brownish-black precipitates and exhibited an excellent organoleptic quality when judged by descriptive sensory analysis. Thirty one volatile flavor compounds, which are the largest number of volatiles among the oil samples prepared, were identified from the oil sample. The oil contained relatively high concentrations of furfurals (sweet candy-like flavor) and pyrazines (roasted-like flavor), that are considered as good contributors to sesame seed oil flavor, and low concentations of aldehydes $(C5{\sim}C10)$ and ketones, which are considerd as bad contributors (oxidized fat-like and painty-like flavors). These results suggest that the roasting condition of $200^{\circ}C$ for 90 min was the best for the oil production in terms of the overall aroma and taste quality under the test conditions (Received July 13, 1993; accepted November 4, 1993).
