Abstract:

AIM: To investigate the effects of sevoflurane-induced vascular protection by apolipoprotein A-1 mimetic D-4F during acute hyperglycemia.  METHODS:Thrty-two male C57BL/6J mice were randomly assigned to 4 groups (n=8). Control group(CON group), D-4Fgroup, acute hyperglycemia group(AHG group), dextrose 2 g/kg (intraperitoneal injection); AHG+D-4F group. Blood glucose, isometric aortic tension, nitric oxide (NO) were measured in mice in the absence or presence of sevoflurane(1.71%). Expressions of eNOS,p-eNOS,Cav-1 in arterioles were determined by Western blot.Superoxide generation species (ROS) were assessed in human umbilical vein endothelial cells (HUVEC) cultured in 5.5 or 20.0 mmol/L glucose with isoflurane (0.5 mmol/L) in the presence or absence of brefeldin A (BFA, 4 μg/mL) or D-4F (0.5 μg/mL). RESULTS: Vasodilation, phosphorylations, NO production of eNOS were decreased while Cav-1 expression was increased during acute hyperglycemia. D-4F increased endothelium-dependent vasodilation (P<0.01) while decreased Cav-1 expression and ROS production in HG+D-4F group after sevoflurane-induction.CONCLUSION: Polipoprotein A-1 mimetic D-4F can enhance sevoflurane-induced vascular protection, decrease Cav-1 expression and ROS production while increase NO production during acute hyperglycemia.

Key words: sevoflurane, vascular protection, D-4F, acute hyperglycemia, NO, ROS
