Effect of physiological mechanical perturbations on intact human myocardial repolarization. (1/69)

OBJECTIVE: The objective of this study was to investigate the relationship between acute decreases in right ventricular volume during Valsalva strain (with resultant changes in autonomic neural tone) and measures of local endocardial repolarization time independent of heart rate and autonomic neural tone. METHODS: Patients implanted with a stimulus to T wave (Stim-T) sensing pacemaker specially adapted to output a validate measure of beat to beat local repolarization (n = 9) performed Valsalva manoeuvers (40 mmHg for 15 s) while paced at a cycle length of 500 ms. Stim-T intervals were measured before and after autonomic blockade (Block: 0.03 mg/kg i.v. atropine +/- 0.15 mg/kg propranolol). Right ventricular end diastolic volume was estimated by simultaneous 2D-echocardiography. RESULTS: Without autonomic blockade, compared to baseline, repolarization significantly prolonged during Valsalva strain (1.1 +/- 0.7%) and shortened during release (-1.4 +/- 1.0%). After block, strain related repolarization prolongation was also observed (1.0 +/- 0.6%), with significantly less release related repolarization shortening (-0.8 +/- 0.8%) compared to pre-block (P < 0.05). Right ventricular end diastolic volume decreased during strain by 11 +/- 10 and 9 +/- 16% from baseline, pre- and post-block respectively (P < 0.05). CONCLUSION: In a chronically instrumented human model, an acute physiologic volume reduction modestly prolongs right ventricular repolarization independent of changes in rate or autonomic tone.  (+info)

Human ejaculatory duct: parameters of smooth muscle motor activity and modulatory role of autonomic drugs. (2/69)

The contractile behaviour and effects of several autonomic drugs on the motor activity of human isolated ejaculatory ducts were investigated. Ejaculatory ducts exhibited spontaneous contractions characterised by an amplitude of 2.35 +/- 0.28 mN, a duration of 62. 9 +/- 3.72 s and a frequency of 0.64 +/- 0.014 waves min-1. Acetylcholine (10-5-10-4 m) induced a slight increase in basal tone and in the frequency of the contraction waves. These effects were suppressed by atropine (10-4 m). Noradrenaline (norepinephrine) increased the basal tone and frequency of spontaneous contractions in a dose-dependent manner. These responses were competitively inhibited by HEAT, a selective a1-adrenoceptor antagonist. These preliminary functional findings, indicating the presence of spontaneous motor activity of human ejaculatory ducts and its possible control by adrenergic agonists, suggests a physiological role for human ejaculatory duct in the propulsion of semen from the seminal vesicle towards the urethra.  (+info)

Heterogenous nature of flow-mediated dilatation in human conduit arteries in vivo: relevance to endothelial dysfunction in hypercholesterolemia. (3/69)

Flow-mediated dilatation (FMD) of conduit arteries is dependent on an intact endothelium, although the mechanisms are not fully understood. Using high-resolution ultrasound, we examined the role of endothelial mediators in radial artery dilatation in response to transient (short period of reactive hyperemia) and sustained (prolonged period of reactive hyperemia, hand warming, or an incremental infusion of acetylcholine into the distal radial artery) hyperemia. After short episodes of reactive hyperemia, FMD was abolished by local infusion of the nitric oxide synthesis inhibitor N:(G)monomethyl-L-arginine (5.3+/-1.2% versus 0.7+/-0.7%, P:<0.001). In contrast, basal vessel diameter and dilatation after prolonged episodes of reactive hyperemia, hand warming, and distal infusion of acetylcholine were not attenuated by nitric oxide synthesis inhibition. Inhibition of cyclooxygenase or local autonomic nervous system blockade also had no effect on FMD. Patients with hypercholesterolemia exhibited reduced FMD in response to transient hyperemia, but the response to sustained hyperemia was normal. These data suggest heterogeneity of endothelial responses to blood flow that are dependent on the characteristics of the flow stimulus. Dilatation after brief episodes of hyperemia is mediated by release of nitric oxide, whereas dilatation during sustained hyperemia is unaffected by NO synthesis inhibition. Hypercholesterolemia seems to differentially affect these pathways with impairment of the nitric oxide-dependent pathway and preservation of non nitric oxide-mediated dilatation to sustained flow stimuli.  (+info)

Inhibition of salivary secretion by lipopolysaccharide: possible role of prostaglandins. (4/69)

Inducible (calcium-independent) nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) are important in the regulation of the function of different organs during infection. A single dose of lipopolysaccharide (LPS; 5 mg/kg ip) within 6 h increased NOS activity (20%) and prostaglandin E (PGE) content (100%) in submandibular glands (SMG) and blocked stimulated salivary secretion in adult male rats. The administration of an iNOS synthesis inhibitor, aminoguanidine (AG), with LPS decreased NOS activity and PGE content. Furthermore, the administration of meloxicam (MLX), an inhibitor of COX-2, blocked the increase in PGE and the production of NO. The incubation of slices of SMG in the presence of 3-morpholinosydnonimine, a donor of NO, increased the release of PGE highly significantly. The incubation of SMG in the presence of a PGE(1) analog (alprostadil) increased the production of NO. These results indicate that LPS activates NOS, leading to NO release, which activates COX, generating PGEs that act back to further activate NOS, causing further generation of PGEs by activation of COX. Because the alprostadil administration inhibited stimulated salivation, LPS-induced inhibition of salivation appears to be caused by increased PGE production. Diminished salivary secretion produces poor oral health; thus the use of COX-2 inhibitors to counteract the effects of inhibited salivation should be considered.  (+info)

Effects of autonomic blockers on linear and nonlinear indexes of blood pressure and heart rate in SHR. (5/69)

Recent results in normotensive Wistar-Kyoto (WKY) rats show that nonlinear method may be more specific to quantify sympathetic and parasympathetic activities than the low (LF) and high frequencies (HF) spectral powers of blood pressure (BP) and R-R interval (RR). The present study extends this conclusion to spontaneously hypertensive rats (SHR). Blood pressure was recorded for 30 min before and after intravenous injection of saline, hexamethonium, atropine, atenolol, or prazosin. Mean level, standard deviation (SD), spectral LF and HF components, and three nonlinear indexes (percentage of recurrence, percentage of determinism, and length index of the recurrence plot method) were used to analyze the BP and RR signals. In conscious SHR, sympathetic but not parasympathetic blockade reduced BP level and LF-BP, and increased nonlinear indexes of BP. RR increased after beta-sympathetic and ganglionic blockade, decreased after parasympathetic blockade, and remained unchanged after alpha(1)-sympathetic blockade. SD-RR decreased after ganglionic and alpha(1) blockade, whereas HF-RR increased after beta-sympathetic blockade. The effects on nonlinear indexes of RR are clear and consistent: only alpha(1)-blockade increased the indexes. Our nonlinear indexes may be useful to investigate cardiovascular functions in normotension and hypertension.  (+info)

Innervation both of peri-orbital structures and of the heart by the cervical sympathetic nerves in mouse, rat, guinea-pig, rabbit and cat. (6/69)

1 In anaesthetized rats electrical stimulation of the intact cervical sympathetic nerve produced frequency-dependent lower eyelid contractions and tachycardia. 2 The tachycardia was caused by excitation of efferent fibres since it was equally evident in the pithed rat preparation, and the right nerve was more effective than the left. By contrast, no differences were seen between the responses to right and left vagal stimulation in either rats or rabbits. 3 Guanethidine inhibited both cardiac and eyelid responses, propranolol only the former and phentolamine only the latter, therby revealing the adrenergic nature of the nerves. Hexamethonium caused partial inhibition and the block was intensified by atropine. 4 The inferior eyelid of mice, guinea-pigs and rabbits as well as the nictitating membrane of rabbits and cats were contracted by cervical sympathetic nerve stimulation. In these species too, tachycardia occurred; this was more pronounced with the right than the left sympathetic nerve. The order of cardiac responsiveness was mouse greater than rat greater than guinea-pig greater than rabbit greater than cat. 5 In guinea-pigs histamine-induced bronchoconstriction was reduced by cervical sympathetic nerve stimulation. 6 That discrete cardiac pathways exist in the cervical sympathetic nerves is suggested by the reproducibility of the effects within any one species. The accessibility of the nerves greatly simplifies the examination of drugs in vivo on two different structures innervated by the sympathetic nervous system.  (+info)

The autonomic nervous system and the bladder during spinal shock--an experimental study. (7/69)

During experimental spinal shock, the urethral muscle responded to drugs earlier than the detrusor muscle. Stimulation with parasympathomimetic drugs caused some rise in intravesical pressure, but an unexpected and much greater rise of intraurethral pressure. Bladder evacuation was achieved with the Crede manoeuvre during spinal shock with the combined effect of alpha adrenergic blockade and beta adrenergic stimulation.  (+info)

Electrophysiology and arrhythmogenic activity of single cardiomyocytes from canine superior vena cava. (8/69)

BACKGROUND: The superior vena cava (SVC) has been proved to be a focal point in the initiation of paroxysmal atrial fibrillation. The autonomic nervous system plays an important role in the genesis of atrial fibrillation. However, the arrhythmogenic potentials of SVC and its responses to autonomic agents are not clear. The purpose of this study was to isolate single SVC cardiomyocytes and to investigate their electrophysiological characteristics, as well as the direct effects of autonomic agents. METHODS AND RESULTS: Canine SVC cardiomyocytes were isolated by perfusion with digestive enzymes. The action potentials and ionic currents were investigated in single SVC cardiomyocytes using the whole-cell clamp technique. Dissociation of the SVC yielded rod-shaped single cardiomyocytes with (n=74, 51%) or without (n=71, 49%) pacemaker activities. There were similar densities of inward Ca2+, delayed rectifier K+, transient inward, inward rectifier K+, and pacemaker currents between SVC cardiomyocytes with and without pacemaker activity. SVC cardiomyocytes with pacemaker activity have, however, greater transient outward currents than those without pacemaker activity. In SVC cardiomyocytes, acetylcholine (5.5 micromol/L) abolished the spontaneous activities, but isoproterenol (10 nmol/L), atropine (10 micromol/L), and phenylephrine (10 micromol/L) accelerated the spontaneous activity and induced the occurrences of early or delayed afterdepolarizations. CONCLUSIONS: These findings suggest that SVC cardiomyocytes have distinct action potentials and ionic current profiles that may be responsible for the arrhythmogenic activity of the SVC.  (+info)

I'm sorry for any confusion, but "autonomic agents" is not a medical term or concept that has a specific definition in the field of medicine. The term "autonomic" refers to the part of the nervous system that regulates involuntary physiological functions, such as heart rate, digestion, and respiratory rate. The term "agents," on the other hand, is often used in computer science and artificial intelligence to refer to software entities that can act on behalf of a user or another entity.

Therefore, "autonomic agents" might refer to software programs that are designed to regulate physiological functions autonomously, but this would be more related to the field of biomedical engineering or artificial intelligence than to medicine itself. If you have more context or information about where you encountered this term, I may be able to provide a more specific answer.
