Outline of Final Research Achievements |
The detailed effects of anesthetics on angiogenesis have not yet been clarified. Angiogenesis is composed of some processes: the release of regulators as such vascular endothelial growth factor (VEGF), cell proliferation, migration, and tube formation. The aim of this study was to determine the effects of intravenous anesthetics on the release of VEGF, cell proliferation, cell migration and in vitro capillary tube formation. As the results, midazolam and diazepam but not propofol and ketamine significantly increased the release of VEGF in A10 cells in a dose dependent manner. Fifty μM of midazolam significantly impaired endothelial cell migration and in vitro capillary tube formation. Diazepam, propofol and ketamine did not show any enhancing or suppressive effects on cell proliferation, cell migration and capillary tube formation. Dexmedetomidine did not show any effects on cell proliferation and cell migration.
