Vasomotor regulation in patients with multiple system atrophy
Journal of Neural Transmission, 2016To investigate the vasomotor regulation in multiple system atrophy (MSA), we simultaneously recorded muscle sympathetic nerve activity (MSNA), heart rate, and blood pressure in 14 MSA patients without syncope and 18 healthy subjects. Resting MSNA bursts were significantly less frequent in MSA patients than healthy subjects (p

Autonomic Nervous System Evaluation of Patients With Vasomotor Rhinitis
The Laryngoscope, 2000AbstractObjective To demonstrate the utility of quantitative neurological laboratory testing of autonomic nervous system dysfunction and to apply this methodology to further study the relation of chronic vasomotor (nonallergic) rhinitis to the autonomic nervous system.Methods It has been suspected that vasomotor rhinitis is due either to a hyperactive ...

THE VASOMOTOR SYSTEM OF THE PULP.
Journal of the American Medical Association, 1903In 1733 Stephen Hales 1 first published the idea that small arteries changed their caliber. He devised the following ingenious experiment: Tying a brass tube into the aorta of a dog and employing a head pressure equal to the normal aortic tension he injected water and measured the outflow per minute from the divided vessels of the intestines.

Systemic vasomotor interaction between nicardipine and hypocapnic alkalosis in man
Intensive Care Medicine, 1992The effects of hypocapnic alkalosis on the vasodilating action of nicardipine were studied in 6 patients after cerebral arterial aneurysm surgery. Each patient served as his/her own control during the 6 steps of the study. T0: baseline; T1: hypocapnic alkalosis alone (PaCO2: 3.5 kPa); T2: hypocapnic alkalosis and bolus injection of nicardipine (30 ...

Differential Responsivity of the Vasomotor Response System to a “Novel” Stressor
Headache: The Journal of Head and Face Pain, 1986SYNOPSIS Bilateral blood volume pulse (BVP) recordings from the frontotemporal artery were obtained from a migraineur and eight non‐migraineurs prior to and following the presentation of a novel laboratory stressor ‐ the consumption of ice water.

Acetaminophen increases pulmonary and systemic vasomotor tone in the newborn rat
Pediatric Research, 2019Acetaminophen is widely prescribed to both neonates and young children for a variety of reasons. In adults, therapeutic usage of acetaminophen induces systemic arterial pressure changes and exposure to high doses promotes tissue toxicity. The pulmonary vascular effects of acetaminophen at any age are unknown.

Control of Systemic and Pulmonary Vasomotor Tone Before and After Birth
1972The last decade has witnessed a striking increase in our knowledge regarding the dynamics of fetal and neonatal circulation. Information has been gathered which has shed light on the various factors that control systemic and pulmonary vascular tones during intrauterine life and the transitional changes that occur at birth. Of considerable importance in

Control of pulmonary and systemic vasomotor tone in the fetus and neonate
American Journal of Obstetrics and Gynecology, 1970Abstract The factors that control the pulmonary and systemic vasomotor tones of the fetus and neonate have been reviewed. In addition, data on the effects of mechanical expansion of the alveoli as well as on those of acid and base infusions on polmonary and systemic hemodynamics in the fetal and neonatal lamb have been presented.

Beyond vasodilatation: non-vasomotor roles of epoxyeicosatrienoic acids in the cardiovascular system
Trends in Pharmacological Sciences, 2007Epoxyeicosatrienoic acids (EETs), derived from arachidonic acid by cytochrome P450 epoxygenases, are potent vasodilators that function as endothelium-derived hyperpolarizing factors in some vascular beds. EETs are rapidly metabolized by soluble epoxide hydrolase to form dihydroxyeicosatrienoic acids (DHETs).

Systemic acidosis after controlled hypotension activates catechol activity in the vasomotor center
Journal of Applied Physiology, 1994Activation of the catechol metabolism, assessed with in vivo voltammetry, in the vasopressor area of the vasomotor center was investigated during systemic acidosis occurring after controlled hypotension. Rats anesthetized with halothane were mechanically ventilated.
