Baroreceptor reflex function.
THE IMPORTANCE of the baroreceptor reflex is to stabilize perfusion pressure in the face of disturbances of circulatory homeostasis. This is achieved by a number of neuronal (8, 29, 37, 48) and humoral (37, 45, 46) regulatory adjustments. These adjustments are initiated by a change in the pressure load at specialized pressure sensors located at the aortic arch and the carotid sinuses. Especiall...
متن کاملNonlinearities of the human carotid baroreceptor-cardiac reflex.
Carotid baroreceptors of nine healthy young men and women were stretched or compressed with neck suction or pressure, before and after beta-adrenergic and cholinergic blockade, to evaluate several nonlinearities of sinus node baroreflex responses. Sinus node inhibition was related linearly to the intensity of brief baroreceptor stimuli over a range extending from carotid-distending pressures of...
متن کاملIL-6 microinjected in the nucleus tractus solitarii attenuates cardiac baroreceptor reflex function in rats.
Recent gene array and molecular studies have suggested that an abnormal gene expression profile of interleukin-6 (IL-6) in the nucleus tractus solitarii (NTS), a pivotal region for regulating arterial pressure, may be related to the development of neurogenic hypertension. However, the precise functional role of IL-6 in the NTS remains unknown. In the present study, we have tested whether IL-6 a...

متن کاملArterial baroreceptor reflex function in borderline hypertensive rats.
With increased dietary NaCl intake (8% NaCl), the borderline hypertensive rat develops hypertension, thus expressing the phenotype of the spontaneously hypertensive parent. Since arterial baroreceptor reflex function is impaired in the spontaneously hypertensive parent, it was the objective of this study to examine arterial baroreceptor reflex function in the borderline hypertensive rat made hy...
