BACKGROUND Previous work on endothelial dysfunction in post-MI heart failure has shown conflicting results. AIM To analyze gender related alterations in NO-, PGI(2)- and EDHF-dependent endothelial function in the thoracic aorta 7 and 42 days after myocardial infarction (MI). METHODS AND RESULTS MI was induced by coronary artery ligation in female and(More)
The biological roles of nitric oxide (NO)-hemoglobin (Hb) derivatives are obscure. It is proposed that NO can function as an allosteric regulator of hemoglobin oxygen-binding properties. We aimed to estimate the effects of NO donors and NO-synthase substrate (L-arginine) on hemoglobin-oxygen affinity (HOA) in experiments in vitro with the various ratios(More)
The aim of the present study was to investigate the role of nitric oxide (NO) in the regulation of hemoglobin oxygen affinity (HOA) in the presence of different oxygen partial pressure. In this research the effect of NO donors on gas-transport, acid-base balance, HOA indexes, metHb, iron-nitrosylhemoglobin amounts, and total nitrite/nitrate concentration(More)
Peroxynitrite (ONOO-) besides its toxic possesses regulatory action that includes the modulation of oxygen binding properties of blood. The aim of this work was to estimate ONOO- effect on the haemoglobin oxygen affinity (HOA) in vitro in presence of different partial pressure of carbon dioxide (CO2). The ONOO- presence in venous blood in conditions of(More)
