Outline of Final Research Achievements	"Seifu,"is a traditional Chinese medicine therapy that promotes improved subcutaneous blood flow and is also used by people with poor circulation.This study hypothesized that "Seifu promotes subcutaneous blood flow and moisturizes the epidermal stratum corneum".We examined whether it is a nursing method that can contribute to maintaining the skin barrier function in winter. Method:In winter, 15 subjects performed skin care on both forearms for 10 minutes, and the stratum corneum moisture meter and laser blood flow meter were used to measure the unskinned areas of the forearms for 30 minutes , and compared with the cases without skin care. Results: There was no significant change in subcutaneous blood flow in either group, but the stratum corneum moisture content was significantly higher in the skin care group. Therefore, the relationship between blood flow and moisturization could not became clear. However, it was proven that skin care moisturizes the epidermal stratum corneum.
Free Research Field	基礎看護技術
Academic Significance and Societal Importance of the Research Achievements	皮下血流改善を促す漢方療法としての「整膚」が、冬期の皮膚バリア機能維持に貢献できる看護方法となり得るかを検証した。その結果、皮下血流量は、対照群・整膚群とも有意な変化を認めなかったが、角層水分量は、整膚群が有意な高値を示した。血流と保湿の関係は明らかとならなかったものの、整膚が表皮角層を保湿することが証明された。以上の結果から、整膚は、一定の手技獲得ができれば、日常場面でだれにでも行える技術であり、冬季の皮膚バリア機能維持に大きく貢献できる看護方法となることが明らかとなった。今後、そのメカニズムを解明していくことで、より確実な看護方法として、新たな看護技術の一つに加えることが可能と考える。
