Quantification of baroreceptor influence on arterial pressure changes seen in primary angiotension-induced hypertension in dogs.
We studied the role of the sino-aortic baroreceptors in the gradual development of hypertension induced by prolonged administration of small amounts of angiotensin II (A II) in intact dogs and dogs with denervated sino-aortic baroreceptors. Short-term 1-hour infusions of A II(1.0-100 ng/kg per min) showed that conscious denervated dogs had twice the pressor sensitivity of intact dogs. Long-term...

15 صفحه اولChronology of blood pressure changes in renal hypertension induced by solid plexiglass clips in the rat
The objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. Saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. Rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...
متن کاملEffect of carotid or aortic baroreceptor denervation on arterial pressure during hemorrhage in conscious dogs.
We studied the effect of chronically denervating aortic baroreceptors (ABR; n = 6) or carotid baroreceptors (CBR; n = 7) on mean arterial pressure (MAP) and heart rate (HR) responses to hemorrhage in the dog. Neither denervation had a significant effect on basal MAP, the variability (standard deviation) of MAP, or resting HR. However, the breakpoint of MAP (defined as the volume of blood remove...
