Figure 4From: β2-adrenergic stress evaluation of coronary endothelial-dependent vasodilator function in mice using 11C-acetate micro-PET imaging of myocardial blood flow and oxidative metabolismHemodynamics and myocardial blood flow index (MBFi) response to adrenergic stress agents norepinephrine (NE) and salbutamol (SB) with and without NOS inhibition. Normal controls are compared to NOS inhibition (L-NAME pretreatment), and endothelial nitric oxide synthase knockout mice (eNOS knockout). NE-stress (green), SB-stress (high dose, dark blue; low dose, light blue). *p < 0.05 vs. NE Control.Back to article page
