Angiotensin-converting enzyme inhibitors have beneficial effects that are presumably mediated by decreased angiotensin II (ANG II) production. In this study, we measure for the first time ANG I and ANG II levels in the interstitial fluid (ISF) space

A 13 amino acid peptide from the calf muscle acetylcholine receptor has been previously shown to bind both snake neurotoxins and acetylcholine. In the experiments reported here a modified complementary peptide (cAChR) derived from that acetylcholine

Increased use of cocaine has increased the incidence of sudden cardiac death concomitantly, likely due to life-threatening arrhythmias and/or myocardial ischemia. The effects of cocaine on regulation of the heart and circulation by the autonomic nerv

Efferent sympathetic activities were simultaneously recorded from two thoracic cardiac nerves in 33 chloralose-anesthetized dogs. Efferent innervation patterns were determined by electrical stimulation prior to recording in each animal. One of the ne

This report outlines a sample configuration of a system which records, stores and analyses, graphically and statistically, neurophysiological and cardiovascular recordings during an experiment. The system is composed of sensitive physiological amplif

This study tested the hypothesis that exogenous infusion of angiotensin II (ANG II) leads to the release of catecholamines [norepinephrine (NE) and epinephrine (EPI)] into the cardiac interstitial fluid (ISF) space of dogs with adrenals intact (AI) (

Background —We have previously demonstrated that angiotensin II (Ang II) levels in the interstitial fluid (ISF) space of the heart are higher than in the blood plasma and do not change after systemic infusion of Ang I. In this study, we assess the

Angiotensin-converting enzyme (ACE) inhibitors (I) have beneficial effects that are presumably mediated by decreased angiotensin II (ANG II) production. However, in vitro assays in human heart extracts have demonstrated that > 75% of ANG II-forming e

Although high thoracic left sympathectomy via an anterior surgical approach is a highly efficacious treatment for refractory ventricular arrhythmias in patients with the long QT syndrome, the degree of sympathetic denervation has been variable, succe

Abstract To clarify the role of Na + i , pH i , and high-energy phosphate (HEP) levels in the initiation and maintenance of ischemia-induced ventricular fibrillation (VF), interleaved 23 Na and 31 P nuclear magnetic resonance spectra were collected o
