| Outline of Final Research Achievements |
Microbubbles, which are very small air bubbles with diameters of less than several tens of micrometers, have chemical and physical properties are different from those of ordinary bubbles. In the present study, the stress-coping effect is investigated by using microbubble bathing. It is revealed that mice given microbubble bathing stress produce three types of humoral lipids for coping the stress. Furthermore, it is confirmed that healthy volunteers were given microbubble bathing stress in their lower legs, and the agaptogenic humoral lipid coping with mental damage was produced. The results of this study revealed that mice given a microbubble bath were affected by the ζ-potential of the microbubbles, where bubbles with a high ζ-potential effectively produced the behavioral adaptogenic glycolipid.

| Academic Significance and Societal Importance of the Research Achievements |
微細気泡(マイクロバブル)は、生物・植物の成長を促進させ、人体にリラックス効果を及ぼすとされていたが、その学術的な側面は未解明であった。マイクロバブルの利用を考えた際、近年研究が進んでいる超音波造影剤や患部にのみ必要量の薬物を送る選択的薬物伝送システムのような血管内に気泡を投入するのではなく、温浴により人体外部からマイクロバブルを使用すれば、血管内に気泡を注入する場合に比べ、一桁大きい数十μm 程度の気泡径で利用できるため気泡生成コストの低減も可能となる。本研究の成果により、マイクロバブル浴による効果を、将来のうつ治療という医学分野への応用、健康維持・増進に役立てられる可能性が示唆された。
