TEK and endothelial dysfunction: We have shown that only two representatives of this group, Angiolin and Tiotriazoline, are capable of exerting a complete effect on the indicators of endothelial dysfunction after PH (with a decrease in sEPCR against an increase in Tie-2, VEGF-B, and Cu/ZnSOD, GPX), which perform protective functions and antioxidative functions.
