The Phosphorylation of Focal Adhesion kinase in The Restenosis of Rat's Vein Graft:Modulation by Olmesartan / 中华高血压杂志

ABSTRACT

Objective To study the expression and phosphorylation of focal adhesion kinase(FAK) in rat's au- tologous vein graft and the olmesartan modulating effect.Methods Autologous external jugular veins were grafted to common carotid arteries in 40 male Sprague Dawley rats.After surgery,rats were randomly assigned to the fol- lowing groups:sham;control;olmesartan treatment(10mg/kg.d by gavage);or physiological saline.The intimal thickness,the I/M in vein grafts was quantitated by HE stain.The expression and phosphorylation of focal adhe- sion kinase were assessed by Western-blotting,PCNA and ?-smooth muscle actin were measured by immunohisto- chemistry.Results Neointimal hyperplasia in control group was characterized by significantly increased intimal thickeness I/M(P
