“…In order to evaluate the theory of atherogenesis from cholesterol, Clarkson and Newburgh (1926) fed rabbits a of several processes of vascular lesion such as mechanical damage; hypercholesterolemia; atherosclerosis; and systemic hypertension 13 . In addition, vascular endothelial relaxation in response to acetylcholine is decreased, thus leading to vasoconstriction and reduced blood flow, as demonstrated by Sun et al 14 in cholesterol-fed rabbits, since this decreased vasodilation may be caused by the presence of lipid plaques in the aorta.…”
