原始语种摘要: Abstract(#br)Insulin resistance has been proposed to play a pivotal role in vasoconstriction due to increased oxidative stress. Hyperthyroidism would amplify cardiovascular disease risk in diabetic patients, though thyroid hormone advance vascular relaxation and reduce vascular contraction by virtue of NO production in vascular smooth muscle cells (VSMCs). Thus, we aimed to investigate the vascular tone and its underlying mechanism in insulin resistance accompanied by hyperthyroidism. Vascular reactivity studies showed that endothelium-denuded thoracic aortic rings from rats fed with high-fat high-sucrose (HFHS) diet and L-T 4 (HFHS+L-T 4 ) exhibited a stronger contractile response to noradrenaline than HFHS rats, which was reversed by L-NAME and GSH. Furthermore, rat thoracic aortic...
