Chronic one-kidney hypertension in rabbits. II. Evidence for a new factor.

abstract：:The migration of medial smooth muscle cells (SMCs) into the intima is proposed to be an important process of intimal thickening in atherosclerotic lesions. The present study examined the possible effect of a novel endothelium-derived relaxing peptide, C-type natriuretic peptide (CNP), on oxidized low-density lipoprote...
