1. A rare mediastinal occurrence of neuroblastoma in an adult: case report
ABSTRACT CONTEXT: Neuroblastoma is the most common extracranial malignant solid tumor that occurs during childhood. It arises from primitive cells and is seen in the adrenal medulla and sympathetic ganglia of the sympathetic nervous system. CASE REPORT: We present a rare case of a 40-year-old man who was diagnosed with the onset of neuroblastoma arising

2. Sympathetic glial cells and macrophages develop different responses to Trypanosoma cruzi infection or lipopolysaccharide stimulation
Nitric oxide (NO) participates in neuronal lesions in the digestive form of Chagas disease and the proximity of parasitised glial cells and neurons in damaged myenteric ganglia is a frequent finding. Glial cells have crucial roles in many neuropathological situations and are potential sources of NO. Here, we investigate peripheral glial cell response to Tryp

3. Estudo anátomo-funcional de glânglios da cadeia simpática torácica na hiperidrose primária / Anatomofunctional study of thoracic sympathetic chain ganglia in primary hyperhidrosis
Introdução: A hiperidrose primária (HP) é uma desordem que afeta negativamente a qualidade de vida de seus portadores. A fisiopatologia da HP não é bem compreendida e acredita-se que uma complexa disfunção do sistema nervoso simpático esteja relacionada com sua etiologia. A ressecção de um ou mais gânglios da cadeia simpática torácica constitui

4. Anandamide injected into the lateral ventricle of the brain inhibits submandibular salivary secretion by attenuating parasympathetic neurotransmission
Our objective was to determine the effect of arachidonylethanolamide (anandamide, AEA) injected intracerebroventricularly (icv) into the lateral ventricle of the rat brain on submandibular gland (SMG) salivary secretion. Parasympathetic decentralization (PSD) produced by cutting the chorda tympani nerve strongly inhibited methacholine (MC)-induced salivary s

5. Estudo da regeneração simpática pós simpaticotomia seletiva experimental (ramocotomia) / Study of sympathetic regeneration post experimental selective sympathicotomy (ramicotomy)
INTRODUCTION: Thoracic sympathectomy is the only definitive and efficient treatment for primary hyperhidrosis. The ramicotomy is a surgical procedure that is as efficient as conventional sympathectomy but more conservative, having less adverse effects then conventional sympathectomy. This procedure was abandoned on account of the high recurrence rate, attrib

6. O sistema nervoso periferico na doença de Machado-Joseph : aspectos clinicos e neurofisiologicos / Clinical and neurophysiological study of the peripheral nervous system um Machado-Joseph disease
Machado-Joseph disease or spinocerebellar ataxia 3 (SCA3/MJD) is the most frequent autosomal dominant ataxia in Brazil and caused by an unstable trinucleotide (CAG) repeat expansion in the 10th exon of the MJD1 gene on chromosome 14q. It is a chronic and debilitating neurologic disorder characterized by cerebellar ataxia, pyramidal dysfunction, dystonia, gaz

7. Targeted ablation of cardiac sympathetic neurons reduces resting, reflex and exercise-induced sympathetic activation in conscious rats
Cholera toxin B subunit conjugated to saporin (SAP, a ribosomal inactivating protein that binds to and inactivates ribosomes) was injected in both stellate ganglia to evaluate the physiological response to targeted ablation of cardiac sympathetic neurons. Resting cardiac sympathetic activity (cardiac sympathetic tonus), exercise-induced sympathetic activity

8. Immunochemical Demonstration of Increased Accumulation of Tyrosine Hydroxylase Protein in Sympathetic Ganglia and Adrenal Medulla Elicited by Reserpine
Chronic administration of reserpine to rats increases, in sympathetic ganglia and adrenal medulla, the activity of tyrosine hydroxylase (EC 1.14.3.x), the enzyme catalyzing the rate-limiting step in the biosynthesis of catecholamines. Immunochemical titration of the enzyme in both adrenal gland and innervated superior cervical ganglia demonstrates that enhan

9. Circadian rhythm of tyrosine hydroxylase induction by short-term cold stress: modulatory action of glucocorticoids in newborn and adult rats.
The trans-synaptic induction of tyrosine hydroxylase [tyrosine 3-monooxygenase; EC 1.14.16.2, L-tyrosine, tetrahydropteridine: oxygen oxidoreductase (3-hydroxylating)] in adrenal medulla and sympathetic ganglia by short-term (1-2 hr) cold stress (4 degrees) exhibits a circadian rhythm which seems to be causally related to the diurnal changes in adrenal gluco

10. Target-independent cholinergic differentiation in the rat sympathetic nervous system
Chemical coding in the sympathetic nervous system involves both noradrenergic and, for a minority of neurons, cholinergic neurotransmission. The expression of the cholinergic phenotype in the developing sympathetic nervous system was examined to determine if coding for cholinergic transmission occurs before or after innervation of peripheral target organs.

11. Synaptic and antidromic potentials of visceral neurones in ganglia of the lumbar sympathetic chain of the cat.
Intracellular recordings were obtained in vitro from two hundred and twenty post-ganglionic neurones of the fourth and fifth lumbar paravertebral ganglia of cats. Thirty-seven percent of neurones tested evoked antidromic responses during electrical stimulation of post-ganglionic fibres in the inferior lumbar splanchnic nerves. Twenty-seven percent of neurone

12. A peptide as a possible transmitter in sympathetic ganglia of the frog.
A search was made in sympathetic ganglia of the bullfrog for a noncholinergic, nonaminergic transmitter that is released by a distinct group of preganglionic axons. These initiate a late slow excitatory postsynaptic potential which lasts for many minutes. The most promising candidate for the role of transmitter is a peptide that resembles luteinizing hormone
