Baroreflex sensitivity modulates vasodepressor response to nitroprusside.
Baroreflex activity is a determinant of the homeostatic response to alteration in blood pressure. We examined the factors that determine the magnitude of the vasodepressor response to sequential incremental intravenous infusions of sodium nitroprusside (NP), 0.05 to 6.4 micrograms/kg/min, in eight male patients with essential hypertension. Each infusion level was of 10 minutes' duration. Change...
متن کاملNervous System Cardiac Baroreflex Sensitivity Is Not Correlated to Sympathetic Baroreflex Sensitivity Within Healthy, Young Humans
The purpose of this study was to evaluate the relationship between the cardiac and sympathetic baroreflex sensitivities within healthy, young humans. The sensitivities of the cardiac and sympathetic baroreflexes were compared in 53 normotensive individuals (28 men and 25 women; age: 24.0 0.9 years; body mass index: 24.0 0.3 cm/kg, mean SEM). Heart rate, arterial blood pressure, and peroneal mus...

The sensitivities of the cardiac and sympathetic baroreflexes were compared in 53 normotensive individuals (28 men and 25 women; age: 24.0 ± 0.9 years; body mass index: 24.0 ± 0.3 cm/kg², mean ± SEM).

متن کاملCardiovascular baroreflex sensitivity attenuates by cisplatin-induced toxicity in rats
Introduction: Cisplatin (CP) therapy may disturb cardiovascular system control. The objective of this study was to find baroreflex sensitivity (BRS) in CP-induced nephrotoxicity in rats. Materials and Methods: Eighteen male and female Wistar rats were randomly assigned to two groups treated with CP (2.5 mg/kg/day) and the vehicle, for five consecutive days, and then were subjected to surgical ...
متن کاملContribution of vascular and neural segments to baroreflex sensitivity in response to postural stress.
BACKGROUND/AIMS The baroreflex pathway has a vascular and a neural segment, both being modulated by variations in peripheral blood pressure (BP). Besides overall baroreceptor sensitivity (BRS), defined as the spectral relationship between changes in peripheral BP and R-R interval within the frequency band of 0.05-0.15 Hz, vascular and neural segment contributions to the overall BRS can be disti...
