Factors regulating the secretion of atrial natriuretic hormone (ANH) and arginine vasopressin (AVP) have not been elucidated fully. In several studies the release of these peptides has been studied by inducing both increased atrial pressure and atrial distension. A few studies employ cardiac
To investigate whether nitric oxide (NO) in the central nervous system is involved in the decrease in renal sympathetic nerve activity (RSNA) during acute cardiac tamponade in conscious rabbits, we examined the effect of 7-nitroindazole (7-NI), a selective inhibitor of neuronal nitric oxide synthase
1. Factors influencing the release of atrial natriuretic peptide (ANP) are not well understood. We chose a conscious euvolaemic canine model of cardiac tamponade to investigate the roles played by atrial blood pressure, transmural atrial pressure, atrial size, and arginine vasopressin (AVP) on ANP
OBJECTIVE
Jejunal nitric oxide (NO) formation is impaired during mucosal hypoperfusion. This study was undertaken to investigate whether this phenomenon could result from a restricted mucosal availability of NO-synthase substrates, ie, oxygen and/or L-arginine.
METHODS
Controlled study using
