Background: A stellate ganglion block (SGB) causes increased blood flow in the maxillofacial region, exhibiting the potential for regenerative effects in damaged tissue. The focus of this study was to understand the efficacy of SGB for regenerative effects against nerve damage. A rat model of the superior cervical ganglion block (SCGB) was created instead of SGB, and facial blood flow, as well as sympathetic nervous system function, were measured. Methods: A vertical incision was made on the left side of the neck of a Wistar rat, and a 5-mm resection of the superior cervical ganglion was performed at the back of the bifurcation of the internal and external branches of the left common carotid artery...

A stellate ganglion block (SGB) is a clinical sympathetic block which can inhibit the body systemic inflammatory response. However, whether and how SGB can attenuate the sepsis-induced acute lung injury remains unclear. Here, we evaluated the effect of SGB on sepsis-induced acute lung injury in rats. Ninety healthy Sprague Dawley (SD) male rats were divided into three groups: the sham operation group (S group), sepsis group (Sep group), and SGB group. The sepsis model rats were produced by cecum ligation and puncture (CLP), and blood samples were taken from the abdominal aorta of the rats at different time points for evaluating the concentration of TNF-α, IL-6, and IL-10 by enzyme-linked immunosorbent assay (ELISA)...

BACKGROUND: Sympathetic denervation exerts protective effects against ventricular arrhythmias (VAs) induced by acute myocardial infarction. The results of a previous study indicated that the distal part of the ligament of Marshall (LOMLSPV ) might be a sympathetic conduit between the left stellate ganglion (LSG) and the ventricles. The present study was designed to compare the effects between LSG and LOMLSPV ablation on ischemia-induced VAs. METHODS: Twenty-nine dogs were randomly divided into sham ablation group (group 1, n=9), LOMLSPV ablation group (group 2, n=10), and LSG ablation group (group 3, n=10)...

Stromal cells/telocytes (SCs/TCs) were recently described in the human adult trigeminal ganglion (TG). As some markers are equally expressed in SCs/TCs and endothelial cells, we hypothesized that a subset of the TG SCs/TCs is in fact represented by endothelial progenitor cells of a myelomonocytic origin. This study aimed to evaluate whether the interstitial cells of the human adult TG correlate with the myelomonocytic lineage. We used primary antibodies for c-erbB2/HER-2, CD31, nestin, CD10, CD117/c-kit, von Willebrand factor (vWF), CD34, Stro-1, CD146, α-smooth muscle actin (α-SMA), CD68, VEGFR-2 and cytokeratin 7 (CK7)...

Autonomic nervous system (ANS) has a crucial role of regulating cardiac function in the physiological state and contributes to the pathogenesis of arrhythmias in the diseased state. The cardiac neuraxis consists of multiple feedback loops consisting of efferent and afferent limbs, mediating neurotransmission to and from the heart. Efferent parasympathetic neurotransmission is mediated by the vagus nerve, while paravertebral sympathetic ganglia relay efferent sympathetic neurotransmission to the heart. The association between autonomic activity and ventricular arrhythmias (VAs) has been studied extensively in both experimental models and humans...

OBJECTIVE: Blood pressure elevation in response to transient renal nerve stimulation (RNS) has been used to determine the ablation target and endpoint of renal denervation. This study aimed to evaluate the safety of transient RNS in canines with normal or ischaemic hearts. METHODS: In ten normal (Group 1) and six healed myocardial infarction (HMI) (Group 2) canines, a large-tip catheter was inserted into the left or right renal artery to perform transient RNS. The left stellate ganglion neural activity (LSGNA) and ventricular electrophysiological parameters were measured at baseline and during transient RNS...

Synaptic plasticity is defined as the ability of synapses to change their strength of transmission. Plasticity of synaptic connections in the brain is a major focus of neuroscience research, as it is the primary mechanism underpinning learning and memory. Beyond the brain however, plasticity in peripheral neurons is less well understood, particularly in the neurons innervating the heart. The atria receive rich innervation from the autonomic branch of the peripheral nervous system. Sympathetic neurons are clustered in stellate and cervical ganglia alongside the spinal cord and extend fibers to the heart directly innervating the myocardium...

OBJECTIVE: The potential for brown adipose tissue (BAT) to be targeted as a therapeutic option to combat obesity has been heightened by the discovery of a brown-like form of inducible "beige" adipose tissue in white fat which has overlapping structural and functional properties to "classical" BAT. The likelihood that both beige and brown fat are recruited functionally by neural mechanisms, taken together with the lack of a detailed understanding of the nature of changes in the nervous system when white adipose tissue (WAT) is transformed to brown, provides the impetus for this study...

Spinal cord injury (SCI) resulting in tetraplegia is a devastating, life-changing insult causing paralysis and sensory impairment as well as distinct autonomic dysfunction that triggers compromised cardiovascular, bowel, bladder and sexual activity. Life becomes a battle for independence as even routine bodily functions and the smallest activity of daily living become a major challenge. Accordingly, there is a critical need for a chronic pre-clinical model of tetraplegia. This report addresses this critical need by comparing, for the first time, resting, reflex and stress-induced cardiovascular, autonomic and hormonal responses each week for 4 weeks in 12 sham-operated intact rats and 12 rats with chronic, complete C6-7 spinal cord transection...

Chronic lead exposure causes peripheral sympathetic nerve stimulation, including increased blood pressure and heart rate. Purinergic receptors are involved in the sympathoexcitatory response induced by myocardial ischemia injury. However, whether P2X4 receptor participates in sympathoexcitatory response induced by chronic lead exposure and the possible mechanisms are still unknown. The aim of this study was to explore the change of the sympathoexcitatory response induced by chronic lead exposure via the P2X4 receptor in the stellate ganglion (SG)...

We report a patient with refractory electrical storm after coronary artery bypass grafting who was successfully treated with thoracoscopic sympathectomy. Cardiac arrest with ventricular tachycardia occurred on postoperative day 2, and the patient required emergency support with venoarterial extracorporeal membrane oxygenation. Frequent episodes of ventricular tachycardia prevented cardiac recovery and weaning from mechanical circulatory support. A percutaneous left stellate ganglion block initially demonstrated successful prevention of ventricular tachycardia, and definitive sympathetic denervation was achieved by a left thoracoscopic sympathectomy...

In Parkinson's disease (PD) there is widespread accumulation in the brain of abnormal α-synuclein aggregates forming intraneuronal Lewy bodies (LB). It is now well established that LB-type α-synuclein aggregates also occur in the peripheral autonomic nervous system in PD, from where it has been speculated they may progressively spread to the central nervous system through synaptically-connected brain networks and reach the substantia nigra to trigger herein dopaminergic dysfunction/degeneration and subsequent parkinsonism...

BACKGROUND: Complex regional pain syndrome (CRPS) is frequently diagnosed in patients recovering from surgery or injury. The symptoms and signs included in consensus diagnostic criteria for CRPS are expected after injury. Categorizing symptoms and signs that occur on a continuum as disproportionate or not is subjective and prone to bias. Psychiatrists and psychologists do not diagnose CRPS and instead measure and treat anxiety and catastrophic thinking on its continuum. Given the expected variation in subjective diagnoses such as CRPS, this study addresses factors associated with use of this diagnosis and how it influences care...

OBJECTIVE: The relationship between the autonomic nervous system (ANS) modulation of the sinus node and heart rate variability has been extensively investigated. The current study sought to evaluate, in an animal experimental model of pacing-induced tachycardia congestive heart failure (CHF), a possible ANS influence on the P wave duration and PR interval oscillations. APPROACH: Short-term (5 min) time and frequency domain analysis has been obtained in six dogs for the following electrocardiographic intervals: P wave duration (P), from the onset to peak of P wave (P p ), from the onset of P wave to the q onset (PR) and from the end of P wave to the onset of q wave (P e R)...
