OBJECTIVE To date, the contribution of basal atrial natriuretic peptide (ANP) levels to resting vascular function in humans is unknown. In the present study we sought to investigate the role of ANP in regulating regional vascular volume and venous tone in healthy subjects. METHODS AND RESULTS We used radionuclide plethysmography to examine the effects of ANP and the ANP-receptor antagonist A7...
UNLABELLED Advanced age is associated with a decreased leg blood flow and reduced physical activity. Endothelin (ET-1), a powerful vasoconstrictor, may play a role in the increased leg vascular tone in older men. objectives: to assess the ET-1-mediated vascular tone in the legs of healthy sedentary older men, both before and after 8 wk of exercise training. methods: in 8 younger subjects (19-50...
The purpose of this paper is to present reported findings of the effects of ovarian steroids on vascular tone. The medical literature was reviewed for relevant contributions.
