Nitric oxide and prostacyclin in ultrasonic vasodilatation of the canine internal mammary artery

Radial artery as graft for coronary artery bypass surgery: Advantages and disadvantages for its usage focused on structural and biological characteristics

“…Hence, the pedicled technique is simultaneously easy to learn and appropriate to minimize irritation to the conduit [35]. In addition, Maruo et al [117] demonstrated in vitro arterial dilation in response to ultrasonic stimulation, because of an endothelium-dependent release of nitric oxide and prostacyclin. The gold standard to prevent RA spasm is systemic administration of diltiazem, in combination with topical spray of papaverine [118] and the intraluminal injection of warm arterial blood including papaverine [24,35,118,119].…”

Ultrasound Modulates Skeletal Muscle Cytokine Levels in Rats with Heart Failure

“…TU was found to modulate various biological processes in tissue cultures and animal models; for example, it decreased concentrations of the pro-inflammatory cytokines TNF-a and IL-6 in vitro (Li et al 2003). Really, therapeutic ultrasound enhanced angiogenesis and production vascular endothelial growth factor (Reher et al 1999;Young and Dyson 1990), vasodilation (Maruo et al 2004) and nitric oxide (NO) generation by endothelial shear stress caused by ultrasonication (Iida et al 2006). Furthermore, TU therapy protects muscle against oxidative stress (Freitas et al 2007) and improves the state of ischemia-reperfusion (Bertuglia 2007).…”

Ondas ultra-sônicas de alta freqüência causam disfunção endotelial em artérias coronárias caninas epicárdicas

“…Also, experimental canine internal artery sonication induces vasorelaxation almost completely by time-dependent endothelial nitric oxide and prostacyclin release, which appears unrelated to tissue heating or endothelial architectural disruption [22].…”
