Exacerbation of adverse cardiovascular effects of aircraft noise in an animal model of arterial hypertension

2020

Arterial hypertension is the most important risk factor for the development of cardiovascular disease. Recently, aircraft noise has been shown to be associated with elevated blood pressure, endothelial dysfunction, and oxidative stress. Here, we investigated the potential exacerbated cardiovascular effects of aircraft noise in combination with experimental arterial hypertension. C57BL/6J mice were infused with 0.5 mg/kg/d of angiotensin II for 7 days, exposed to aircraft noise for 7 days at a maximum sound pressure level of 85 dB(A) and a mean sound pressure level of 72 dB(A), or subjected to both stressors. Noise and angiotensin II increased blood pressure, endothelial dysfunction, oxidati…

LSC Abstract – Lung-derived prostacyclin (PGI) in endothelial dysfunction in db/db mice

2016

Aim: Increased risk of pulmonary hypertension and not clear response of pulmonary endothelium to diabetes were reasons to compare nitric oxide (NO) and PGI-dependent function in pulmonary and systemic circulation in diabetes type II. Methods: In fasted db mice (male, 20 weeks) we compared the function of pulmonary (isolated perfused lung-IPL) and aortic endothelium (wire myograph). It was supported by determination of nitrite(NO 2 - )/nitrate(NO 3 - ), PGI production, immunostaining (IMS) and western blot. Results: In diabetic IPL NO-dependent modulation of hypoxic pulmonary vasoconstriction was impaired but filtration coefficient increased; response to U46619 was enhanced; cumulative gener…

Mildronate, a Regulator of Energy Metabolism, Reduces Atherosclerosis in apoE/LDLR<sup>–/–</sup> Mice

2009

<i>Background/Aims:</i> Mildronate, an inhibitor of <i>L</i>-carnitine biosynthesis and transport, is used in clinics as a modulator of cellular energy metabolism and is a cardioprotective drug. <i>L</i>-Carnitine is a pivotal molecule in fatty acid oxidation pathways and its regulation in vasculature might be a promising approach for antiatherosclerotic treatment. This study was performed to evaluate the effects of mildronate treatment on the progression of atherosclerosis and the content of <i>L</i>-carnitine in the vascular wall. <i>Methods:</i> ApoE/LDLR<sup>–/–</sup> mice received mildronate at doses of 30 and 100 …
