From: Early endothelial dysfunction in cholesterol-fed rabbits: a non-invasive in vivo ultrasound study.
Relaxation to acetylcholine (ACh) and to sodium nitroprusside (SNP) of abdominal (panels A and C) and thoracic (panels B and D) aortic rings from rabbits fed or not with a cholesterol diet for 2 or 8 weeks Aortic rings were exposed to cumulative doses of the indicated agent. Values are presented as percentage of relaxation relative to a phenylephrine precontraction (1 μM). Values are expressed as mean ± SEM (n = 8). *P < 0.05 vs Week 0.
