The purpose of this study was to examine the effects of abdominal meridian massage with combination including capsaicin upon body composition and temperature of skin for 24 obese women. Twelve women were assigned to experiment group, twelve women to control group. The subjects participated in abdominal meridian massage for 6 weeks. The experiment group was conducted to do abdominal meridian massage with combination including capsaicin while the control group was conducted to do it with massage cream for 2 times in a week. The results of this study were as follows : Experiment group showed bigger tendency of decrease than control group in change of weight, BMI, fat mass, fat ratio and waist circumference. The average body weight decreased significantly by 2.45kg(p<.001) from the pretest level of 64.02kg to 61.57kg and the upper-waist circumference decreased significantly by 3.25cm(p<.001). Experiment group showed significant difference than control group in change of temperature of abdominal skin by 9.39%(p<.001) from the pretest level of 30.33℃ to 33.18℃. In conclusion, the abdominal meridian massage with combination including capsaicin had a positive effect on obese women's body composition, waist circumference and the temperature of abdominal skin and it can be applied as a nursing intervention to decrease the abdominal obesity.

목적: 본 연구는 수확시기별 단풍나무 추출물의 항산화 활성과 항균 활성을 비교하여, 생리활성이 높은 적정 수확시기 및 이용시기를 도출하고자 하였다. 방법: 단풍나무 잎을 수확 시기별로 추출한 후, 총 폴리페놀 함량, 총 플라보노이드 함량, DPPH radical 소거활성, 세포독성, 그리고 Staphylococcus aureus, Bacillus subtilis 그리고 Pseudomonas aeruginosa에 대해 항균 활성을 측정하였다. 결과: 단풍나무 추출물의 항산화 함량과 항산화 활성은 7월과 11월에 가장 높게 나타났다. RAW 264.7 세포에 대해서 7월과 11월의 시료 5-100 µg/mL 농도에서 높은 세포생존율을 나타냈다. 3종의 균주에 대한 항균 실험 결과, 시기별로 항균 활성에 차이를 나타냈다. 결론: 단풍나무 추출물은 항산화 함량, 항산화 활성 및 항균 활성에서 시기별 차이를 보였으며, 항산화능이 높은 7월과 11 월의 100 µg/mL 농도에서 높은 세포생존율을 보였다. 따라서 단풍나무 추출물을 천연 항산화제로서 활용할 경우 수확시기는 중요한 요소로 작용하는 것을 확인할 수 있었으며 7월과 11월이 최적의 수확 시기임을 확인하였다. Purpose: This study aimed to investigate the optimal collection time of Acer palmatum extract (APE) through anti-oxidant and anti-bacterial activities. Methods: We confirmed the anti-oxidant activity of APE by estimating the total polyphenol content, total flavonoid content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effect, and cell viability. In addition, we determined anti-bacterial activities against Staphylococcus aureus, Bacillus subtilis, and Pseudomonas aeruginosa during growth. Results: Anti-oxidant activities of APE peaked in July and November. RAW 264.7 displayed high cell viability in APE concentrations of 5–100 µg/mL in July and November. As a result of conducting anti-bacterial activities, seasonal variation of APE against three bacteria was exhibited. Conclusion: The anti-oxidant and anti-bacterial activities of APE showed seasonal variation, and high cell viability in July and November; therefore, consideration of the optimal seasonal collection time for Acer palmatum could be an important factor attributing to its natural antioxidant properties and the optimal collection time was confirmed especially to be in July and November.
