Neurohumoral control of colonic motility in the rabbit

open access: yes, 1983
Colonic motility was examined in the proximal (taeniated) and distal (nontaeniated) colon of New Zealand White rabbits. Colonic myoelectric and contractile activities were recorded by bipolar electrodes and extraluminal strain gauges sewn on the ...

Role of sympathetic innervation in the feline continence process under natural filling conditions

open access: yes, 1992
1. The effect of the sympathetic innervation on the bladder detrusor muscle was assessed in pentobarbitone-anesthetized cats by measuring the changes in bladder wall tension that occurred during sympathetic ganglion blockade after filling the bladder at

Circulating Catecholamines Modulate Ischemic Brain Damage

open access: yes, 1986
In search of factors influencing the outcome of an ischemic insult, we induced 10 min of forebrain ischemia in rats and assessed neuronal necrosis by quantitative histopathology after 1 week of recovery.

Local sympathetic function in human skeletal muscle and adipose tissue assessed by microdialysis.

open access: yes, 2002
Item does not contain fulltextBACKGROUND: In response to stressors and pathophysiologic conditions, sympathetic neuronal outflows can change heterogeneously among body organs and tissues. This study examined the validity of microdialysis and measurements

Spinophilin regulates central angiotensin II-mediated effect on blood pressure

open access: yes, 2011
Central angiotensin II (AngII) plays an important role in the regulation of the sympathetic nervous system. The underlining molecular mechanisms are largely unknown. Spinophilin (SPL) is a regulator of G protein-coupled receptor signaling.

Cerebrovascular CO2 reactivity in normotensive and hypertensive man.

open access: yes, 1976
Cerebrovascular reactivity to CO2 inhalation and voluntary hyperventilation was studied in seven normotensive subjects and nine hypertensive patients without clinical or angiographical signs of arteriosclerosis.

Changes in cortical impedance and EEG activity induced by profound hypotension

open access: yes, 1975
Fourteen late juvenile monkeys were subjected to a single 30-min episodes of markedhypotension using an infusion of trimethaphan. Afterward, blood pressure was rapidly restored to and maintained at preinsult levels with an intravenous drip of ...

Heterogeneity of autonomic regulation in hypertension and neurovascular contact

open access: yes, 2002
OBJECTIVE: Brainstem neurovascular contact (NVC) may interfere with central autonomic regulation and contribute to essential hypertension. We have previously shown that patients with autosomal-dominant hypertension, brachydactyly, and NVC feature extreme

Relaxant effect of capsaicin in the rat gastric fundus

open access: yes, 1991
The effect of capsaicin was studied in precontracted longitudinal muscle strips of the rat gastric fundus. Capsaicin induced a relaxation in the concentration range 10(-7)-10(-6) M. The relaxation induced by 10(-6) M capsaicin was completely prevented by

Brain blood flow autoregulation and metabolism during halothane anesthesia in monkeys

open access: yes, 1977
Past studies suggest that halothane causes cerebrovascular dilatation and increased cerebral blood flow (CBF); these properties may be relevant to its use for neurosurgical procedures.
