    The effects of calcium channel blockers are not related to their chemical structure in the collar model of the rabbit
    (Cambridge Med Publ, 2007) Yasa, M.; Kerry, Z.; Reel, B.; Anacak, G. Yetik; Ertuna, E.; Ozer, A.
    Placing a silicone collar around the rabbit carotid artery induces intimal thickening, an early stage in atherosclerosis and restenosis. We investigated whether treatment with oral pranidipine, a new potent, long lasting dihydropyridine calcium channel blocker (CCB), inhibited collar-induced intimal thickening in addition to the changes in vascular reactivity usually observed in this model. Pranidipine treatment did not inhibit collar-induced intimal thickening. Placing the collar around the carotid artery resulted in the characteristic changes in vascular reactivity, such as increased sensitivity to 5-hydroxytryptamine. Treatment with N-omega-nitro-L-arginine (100 mu M) and pranidipine, however, did not affect collarinduced changes in vascular reactivity. From results of this and previous studies, we conclude that pranidipine does not prevent collar-induced intimal thickening or collar-induced changes in vascular reactivity. Not all CCBs prevent collarinduced intimal thickening, suggesting that the effects of these agents are not related to their chemical structure and/or their calcium channel-blocking actions.

Telomeric restriction analysis of vascular smooth muscle cells following balloon angioplasty in rabbits. J Physiol Biochem, 65 (3), 243-250, 2009. Intimal hyperplasia due to smooth muscle cell proliferation and migration has been reported to be responsible for the pathogenesis of atherosclerosis and restenosis, manifested following balloon angioplasty. In this study, we employed the balloon angioplasty model to study telomere length regulation in proliferating vascular smooth muscle cells. Our results showed that balloon angioplasty in iliac arteries resulted in intimal hyperplasia due to proliferation of the smooth muscle cells and small size telomeric restrictional fragments were evident in injured arteries.
