The role of postabsorptive mechanisms in long-term control of drinking behavior, Na+ balance, and arterial pressure was examined in Dahl salt-sensitive (DS) and salt-resistant (DR) rats. NaCl (0.15 M) was infused (0.5 ml/h) into either the inferior vena cava (IVC) or the portal vein (PV) for 7 days, and then 1.5 M NaCl was infused for 10 days. During 1.5 M(More)
Using a computer assisted telemetric system, we have re-examined the effect of sino-aortic denervation (SAD) on the changes in arterial blood pressure (AP) and heart rate (HR) during sleep in the rat suitably recovered from the operation. Eight 1 hourly polygraphic recordings were performed 4 weeks after the initial SAD surgery. In the SAD rats, the(More)
