| Outline of Final Research Achievements |
In cardiovascular surgeries undergoing with cardiopulmonary bypass (CPB), it has been shown that platelet activity is temporarily reduced after weaning from CPB, which is one cause of postoperative bleeding.However,the molecular biological mechanisms are still largely unknown. In this study, we conducted research based on the hypothesis that small RNA called microRNA is associated with platelet dysfunction after CPB.
As a result, it was suggested that the expression of some microRNAs in platelets after CPB up-regulated and this may cause the down-regulation of the expression of platelet membrane proteins related to hemostasis.

| Academic Significance and Societal Importance of the Research Achievements |
人工心肺離脱後の血小板機能低下の分子生物学的なメカニズムがmicroRNAレベルで引き起こされている可能性を示唆したことが本研究の学術的意義であると考えられる。また、本研究の社会的意義として、それらのmicroRNAをターゲットにした治療法に展開できる可能性を有していることが挙げられる。
