1. Nitric oxide (NO)-mediated, endothelium-dependent vasodilator function in rat aortic smooth muscle was investigated in an in vitro model of endogenous vascular superoxide anion stress, generated by pretreatment with the Cu/Zn superoxide dismutase (SOD, EC 1.15.1.1) inhibitor, diethyldithiocarbamate (DETCA). 2. Contraction to noradrenaline (NA, 1 nM - 1(More)
We have developed a photometric microassay for the assessment of total antioxidant status in plasma at physiological pH and temperature and applied it to evaluate experimental oxidant stress in vivo associated with endothelial dysfunction in vitro. Rat plasma or l-ascorbic acid inhibited the peroxidase-mediated accumulation after 6 min at pH 7.4 and 37°C of(More)
Nitric oxide (NO)-mediated vasodilation induced by hyperinsulinaemia might involve an indirect action which promotes agonist-stimulated endothelial function. Our aim was to attempt to demonstrate such modulation of endothelium-dependent vasodilation by insulin in the rat isolated aorta. We found that vasodilation in response to acetylcholine, but not to(More)
Nested reverse transcription (RT)-PCR and SYBR Green real time PCR protocols for the intravitam detection of rabies virus genomic RNA were tested with clinical samples for the first time from rabies suspected animals (n=12). With SYBR Green real time PCR, five saliva samples were detected as positive, hence confirming that, for the sake of antemortem(More)
