In order to clarify the role of the vagus nerve in the secretion of gastric inhibitory polypeptide (GIP), experiments were performed on dogs. Response of plasma GIP to intraduodenal instillation of glucose was slightly lower in a group which received atropine, than in a group of normal dogs. The response of plasma GIP to intraduodenal glucose load was not different between vagotomized dogs and ...

To determine if electrical stimulation of autonomic nerves could excite nonadrenergic inhibitory motor pathways in the guinea pig respiratory system in vivo, we studied the effects of electrical stimulation of the cervical vagi and sympathetic nerve trunks on pressure changes (P(p)) within an isolated, fluid-filled cervical tracheal segment which reflected changes in trachealis muscle tone. We ...

BACKGROUND Stimulation of the vagus nerve has modulating, anti-inflammatory effects on the cellular immune response in the blood and the spleen, stabilizing brain function. Here, we aimed to investigate its potential effects on immune-to-brain communication focusing on neurophysiological readouts and leukocyte migration to the brain during severe sepsis-like endotoxemia. METHODS Systemic infl...

A 36-year-old woman presented with glossopharyngeal and vagus nerve palsy, which proved to be herpes zoster based on the high titers of Varicella zoster virus antibody in her serum. Thin-section T1-weighted images with contrast media demonstrated swelling and distinct contrast enhancement of the glossopharyngeal and vagus complex, mimicking a tumor. Following MR imaging, the size of the nerve c...

reported are a total of 81 microsurgical operations for cranial nerve root decompression comprising of 66 trigeminal, 10 facial, one vestibular, one vagus and three accessory nerve dysfunction syndromes from 1983 to 1990. almost all cases of trigeminal neuralgia (tng) secondary to vascular (59 cases) and minute mass (10 cases) compression, and those with hemifacial spasm (hfs) (nine out of 10 c...

Background: Stroke is the leading cause of adult death in China and worldwide, characterized by high morbidity, disability, mortality, recurrence economic burden, often to various functional impairments, such as motor impairment, sensory swallowing consciousness impairment cognitive impairment. Therefore, finding effective intervention methods currently a hot difficult issue stroke rehab...

BACKGROUND Although the pathogenesis of sudden infant death syndrome (SIDS) is not understood, one of the major hypotheses is that a subtle defect in respiratory circuitry is an important underlying factor. The vagus nerve is a critical component of respiratory control, but its neuroanatomic complexity has limited its investigation in human disease. METHODS Correlating developmental studies o...

We previously showed that specific angiotensin II (Ang II) binding sites are present in the canine nodose ganglion and peripheral vagus nerve, and that unilateral removal of the nodose ganglion results in loss of binding in the ipsilateral nucleus tractus solitarii and the dorsal motor nucleus of the vagus. An association of Ang II binding sites with both afferent and efferent vagal fibers is c...

PLATE 74. It has been shown by one of us (I) that the normal production of impulses in the region of the sino-auricular node is inhibited by stimulation of the right vagus nerve to a greater extent than by stimulation of the left. Earlier observations, which are fully discussed in that paper, had indeed indicated that such might prove to be the case ; but a clear demonstration of the prepondera...

Abstract Aims Vagus nerve injuries occur in up to 42% of patients following anti-reflux operations. Vagal may have a significant impact on patients’ quality life after benign Upper GI hiatal surgery, and go unrecognised. We aimed explore surgeons’ knowledge practice regarding consenting, identifying the vagus intraoperatively, managing injuries. Methods A pilot survey was distributed General Su...
