Outline of Final Research Achievements

The current study was conducted to evaluate the relationship between memory disturbance and endothelial dysfunction in the adolescent mice undergoing the volatile anesthetic sevoflurane inhalation. In the model with memory disturbance, we found that the endothelium-dependent relaxation of the mice aorta was significantly impaired, whereas the action mechanisms have been unclear. Further studies will require to verify them.

Academic Significance and Societal Importance of the Research Achievements

本研究で明らかにされた揮発性麻酔薬セボフルランによる恐怖記憶定着モデル動物での血管内皮機能障害は、臨床麻酔の現場で恐怖を強く感じた個体で血管の機能が異常をきたす可能性を示唆するものである。すなわち、精神ストレスと心血管障害との因果関係の一部を明らかにした点で意義があると考えられる。
