Objectives. To explore the effect of inorganic forms of magnesium (magnesium nitrate, magnesium sulfate, magnesium chloride) on the course of experimental ischemic stroke (II). Material and methods. The experimental ischemic stroke caused by the occlusion of two carotid arteries in Wistar rats was
Effects of nitrates NaNO(3), KNO(3), Mg(NO(3)) 2 on animals (Wistar rats) were studied on the basis of the experimental model of ischemic stroke induced by the occlusion of two carotid arteries. The animals were divided into two groups: the main group (n=60) and the control group (n=30). Three
OBJECTIVE
To perform an ecological study in an effort to generate questions concerning the preventive impact of various cardiovascular drugs on mortality from stroke and ischaemic heart disease (IHD) in the community, and to explore the association between sales of nitrates and mortality from stroke
Nitric oxide (NO) has multiple effects that may be beneficial in acute stroke, including lowering blood pressure, and promoting reperfusion and cytoprotection. Some forms of nitric oxide synthase inhibition (NOS-I) may also be beneficial. However, high concentrations of NO are likely to be toxic to
OBJECTIVE
To reveal a protective role of the nitrite/nitrate reductase system in NO- synthase (NOS) inhibition in ischemic stroke.
METHODS
An effect of the non-selective NOS inhibitor Nω-nitro-L-arginine (L-NNA) introduced in dose of 25 mg/kg and nitrates (КNO3, NaNO3, Mg(NO3)2, Ca(NO3) in doses of
OBJECTIVE
Nitric oxide, NO, is the key vasorelaxing agent produced by vascular endothelium. Stable end products of NO oxidation, nitrate and nitrite (NOx), are considered as markers of endothelial dysfunction associated with hypertension. Our goal was to compare NOx levels in patients with
Endothelium-derived nitric oxide is beneficial in experimental stroke. We assessed plasma NO levels in patients with acute stroke and their association with both severity and outcome. Plasma nitric oxide (NO), assessed as nitrate/nitrite (NOx), cyclic guanosine monophosphate (cGMP, second messenger
BACKGROUND
Nitric oxide has several effects that may be beneficial in ischaemic stroke and useful in the management of hypertension in acute stroke. Some forms of nitric oxide synthase inhibition may also be beneficial. However, high concentrations of nitric oxide are likely to be toxic to brain

To assess the association of nitrate use with cardiovascular events in patients with heart failure with preserved ejection fraction (HFpEF).Patient data were collected from the Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Stroke-prone spontaneously hypertensive rats (SHRSP) demonstrate impaired endothelium-dependent relaxation and often develop brain injuries. We investigated whether the regulatory mechanism for endothelial NOS (eNOS) phosphorylation and activation is altered in the cerebral cortex of SHRSP at a
The manganese-dependent superoxide dismutase (MnSOD) Ala16Val single nucleotide polymorphism (SNP) has shown to be associated to risk factors of vascular diseases. Brain-Derived Neurotrophic Factor (BDNF) plays an essential role in the plasticity and neuronal regeneration of the brain after vascular
OBJECTIVE
To investigate the role of Tc-MIBI gated SPECT imaging following the administration of low-dose dobutamine plus nitrate (LDD+nitrate) in the assessment of left ventricular function and the perfusion of hibernate myocardial tissue.
METHODS
The study group comprised 29 patients diagnosed as
