Figure 7.
Endothelium-independent vasodilation in SAT and VAT isolated arterioles. The intraluminal diameter of SAT (A) and VAT (B) isolated arterioles was measured in response to increasing concentrations of SNP (10−9−10−4 M) in obese subjects (n = 40) and non-obese controls (n = 40). The absolute difference in SNP-induced vasodilation between Hcy-preconditioned and unconditioned SAT (C) and VAT (D) arterioles in obese subjects (n = 10) and non-obese controls (n = 10). All measurements are presented as means ± standard error (SE).
