Effect of nifedipine on arterial pressure lability of sino-aortic deafferentated rats.


Sino-aortic deafferentation (SAD) in rats produces arterial pressure lability (APL) whose mechanisms are not completely understood. In the present study we infused nifedipine (500 micrograms kg-1 min-1) for 30 min into sham-operated and acute SAD rats (24 h) and the changes in mean arterial pressure (MAP) and APL were measured during this period by a… (More)
