... baroreceptor reflex was increased during orthostatic stress and whether failure to develop this increase was associated with poor orthostatic tolerance. Three groups of subjects were studied: asymptomatic controls; patients investigated for suspected posturally related syncope but who had normal responses...

...-containing solution resulted in falls of blood pressure and heart rate in both rats and cats. 3. A more precise application of substance P to the first synapse of the baroreceptor reflex by micro-injection into defined areas of the nucleus of the solitary tract also led to an activation of the baroreceptor...

.... The central pressor actions of substance P could be markedly attenuated. by intracerebroventricular pretreatment with the derivative of γ-aminobutyric acid, baclofen. 5. We conclude that the baroreceptor reflex is disturbed in spontaneously hypertensive rats. Substance P may contribute to the pathogenesis...

...J. V. Jones; J. S. Floras 1. The time course of changes in baroreceptor reflex sensitivity during the development of renovascular hypertension was studied in male Wistar rats in which the left renal arteries were constricted by silver wire clips of 0.18 mm internal diameter. 2. Groups of animals...

...J. D. Marker; T. S. Miles; G. C. Scroop 1. The effects of vascular infusions of acetylcholine, angiotensin II, noradrenaline and prostaglandin F 2α on the baroreceptor reflex were studied in the anaesthetized greyhound. 2. Vertebral artery infusions of low doses of angiotensin II...
