Sinoaortic denervation produces sodium retention in Dahl salt-sensitive rats.
The role of the arterial baroafferent signals in sodium (Na) homeostasis was examined in salt-sensitive rats. Sodium balances, water balances, and systolic arterial pressure (SAP) were measured for 3 weeks in sinoaortic denervated (SAD) or sham denervated (Sham) Dahl salt-sensitive (S) and salt-resistant (R) rats fed a standard-salt diet (0.4% NaCl). In R rats, there was no significant differen...
متن کاملHemodynamic patterns during desynchronized sleep in intact cats and in cats with sinoaortic deafferentation.
In unanesthetized, unrestrained cats, placed in a sound-attenuated cage, stroke volume and cardiac output were continuously monitored by an electromagnetic flow transducer chronically implanted around the ascending aorta, arterial pressure was measured by means of a femoral catheter connected to a strain-gauge transducer, and heart rate by a cardiotachograph. Total resistance was computed by di...
متن کاملThe effects of gap junction modulators on the rhythmic contractions in aortas isolated from rats subjected with sinoaortic denervation.
Following sinoaortic denervation (SAD) rats present intense arterial pressure lability without sustained hypertension. This study aimed to verify the effects of heptanol (a putative gap-junction blocker) and tetraethylammonium (TEA, a putative gap-junction activator) on rhythmic contractions (RCs) and vascular reactivity in the aortas isolated from SAD and Sham-operated (SO) rats. Rhythmic cont...
