Effects of vitamin C treatment on collar-induced intimal thickening
Vitamin C has efficient antioxidant properties and is involved in important physiological processes such as collagen synthesis. As such, vitamin C deficiency leads to serious complications, including vascular diseases. The aim of this study was to investigate the effects of vitamin C treatment on collar-induced intimal thickening. Rabbits were fed a normocholesterolemic diet and a non-occlusive...
متن کاملRole of polymorphonuclear leukocytes in collar-induced intimal thickening in the rabbit carotid artery.
In this study, the involvement of polymorphonuclear leukocytes (PMNs) in the development of intimal thickening was investigated. A fibromuscular intima was induced by placing a silicone collar around the rabbit carotid artery for 3 days or 2 weeks; the contralateral artery was sham operated. Rabbits received placebo treatments (groups 1 and 3), granulocyte-colony stimulating factor (group 2; G-...
متن کاملProtection by shear stress from collar-induced intimal thickening: role of nitric oxide.
Nitric oxide (NO) has potent relaxant and antiproliferative effects on vascular smooth muscle cells, which may represent an important antiatherosclerotic mechanism. Since one of the major stimuli for NO release is flow-related shear stress, we have investigated (1) the effect of increased shear stress on neointimal formation induced in the rabbit carotid artery by enclosing the vessel in a nonc...
متن کاملMechanisms and prevention of intimal thickening of the autogenous vein grafts--possible involvement of nitric oxide--.
Platelet thrombosis, intimal hyperplasia, and the progression of atherosclerosis are the most important factors determining the patency of vein grafts for arterial occlusive disease. Interactions between aggregating platelets and the vessel wall play an important role in all of these processes. The endothelium modulates the underlying vascular smooth muscle by releasing nitric oxide (NO), a pot...
متن کاملChanges in the caldesmon isoform content and intimal thickening in the rabbit carotid artery induced by a silicone elastomer collar.
The presence of a silicone elastomer collar around one carotid artery of a rabbit induces thickening of the tunica intima. We used immunoblotting to study quantitatively changes in the isoforms of caldesmon, a protein implicated in the regulation of contractility in smooth muscle, while also monitoring the histological changes during 28 days after collaring. Control rabbit carotid arteries (n =...
