Orthoradiography of Heart and Aorta

چکیده
Apparatus and Technique.?The source of energy we employ for the X-ray tubes is a Snook High Tension Transformer. The orthoradiograph is Groedel's modification of the Levy-Dorn apparatus. The Snook apparatus, invented by Snook of Philadelphia, introduced by Dr Leonard into this country, and made by Newton of London, enables this work to be carried on with a minimum of difficulty. It consists of three parts :?The main current, a constant one, is converted into an alternating one by means of a motor

Vasorelaxatory Effect of Vitis vinifera Extract on Rat Aorta
Reports have shown the antioxidant, hypotensive, hypolipidemic and vasodilatory effects of grape (Vitis vinifera L.) seed extract. We have recently shown the relaxatory effect of grape leaf extract on rat uterus and reduction of frog heart rate and contractility. The aim of the present study was to investigate the relaxant effect of Vitis vinifera leaf hydroalcoholic extract (VLHE) on rat thora...

متن کاملThe effect of omega- 3 polyunsaturated fatty acids on endothelial tight junction occludin expression in rat aorta during lipopolysaccharide-induced inflammation
Objective(s): Occludin is essential for proper assembly of tight junctions (TJs) which regulate paracellular endothelial permeability. Omega-3 polyunsaturated fatty acids (Ω-3 PUFA) protect endothelial barrier function against injury. Materials and Methods: We examined anti-inflammatory effect of Ω-3 PUFA intake (30 mg/kg/day for 10 days) on expression and location of occludin in the aorta of ...
متن کاملChanges in vascular reactivity of the coronary artery and thoracic aorta in the delta sarcoglycan null mutant mice
Introduction: Mutations in the delta sarcoglycan gene (d-SG) cause limb-girdle muscular dystrophy type 2F with structural and functional alterations in cardiac, smooth and skeletal muscle. The objective of the present study was to improve information about changes in vascular reactivity of the thoracic aorta and the coronary artery in the perfused heart of the d-SG-null mutant mouse model. ...
