An anatomic study of the vagus nerves in their thoracic course below the pulmonary plexus, and in their distribution to the stomach has been made in 50 cadavers. Because of the recent increase in interest in the relationship of the vagus nerves to peptic ulcer, tlie literature was reviewed and revealed relatively few detailed descriptions of the anatomy of the nerves in this area and difference...

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 o...

Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography (PET/CT)imaging with 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly d...

INTRODUCTION Inflammation plays a major role in the multifactorial process of trauma associated coagulopathy. The vagus nerve regulates the cholinergic anti-inflammatory pathway. We hypothesized that efferent vagus nerve stimulation (VNS) can improve coagulopathy by modulating the inflammatory response to hemorrhage. METHODS Wistar rats (n = 24) were divided in 3 groups: Group (G1) Sham hemor...

EDITORIAL SYNOPSiS A study of the response of the ileocaeco-colic sphincter2 of the cat and dog to sympathomimetic and parasympathomimetic drugs and to stimulation of the autonomic nerves is reported. The response to drugs in vivo is identical with that previously noted in vitro, namely, contraction of the sphincter by adrenaline, noradrenaline, and acetylcholine, and relaxation by isoprenaline...

Vocal fold paralysis may occur for a wide range of reasons, from cardiac chamber enlargement, intoxication by chemical products, and mediastinal, neck, lung and intracranial tumors. Given the vast array of possibilities and the various points where the vagus and recurrent laryngeal nerves (the latter is a branch of the first and innervates most laryngeal intrinsic muscles) may be injured, often...

It has been generally held in the past that the innervation of the coronary vessels of the mammal is peculiar with respect to the systemic blood vessels in that the parasympathetics, the vagi, were considered to be coronary vasoconstrictors and the sympathetic nerves, primarily coronary vasodilators. The evidence for this comes largely from work reported by Wiggers (l), Anrep and Segall (Z), Ho...

THERE appears to be general agreement that in the mammalian heart vagal stimulation has no effect on ventricular contractility. This was demonstrated by Drury2 who used the myocardiograph of Cushny and was confirmed by optical determination of the intraventricular pressure of the artificially driven heart; when a cardiac alternans existed and weak faradic stimulation of the cardiac sympathetic ...

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 ...
