Fluorescent Identification of Sympathetic Ganglia During Thoracoscopy

Imaging neural crest cell dynamics during formation of dorsal root ganglia and sympathetic ganglia.

The neural crest is a migratory population of cells that produces many diverse structures within the embryo. Trunk neural crest cells give rise to such structures as the dorsal root ganglia (DRG) and sympathetic ganglia (SG), which form in a metameric pattern along the anterior-posterior axis of the embryo. While static analyses have provided invaluable information concerning the development of...

Modulation of Synaptic Amplification in Sympathetic Ganglia

Clinical Identification of the Vertebral Level at Which the Lumbar Sympathetic Ganglia Aggregate.

BACKGROUND The location and the number of lumbar sympathetic ganglia (LSG) vary between individuals. The aim of this study was to determine the appropriate level for a lumbar sympathetic ganglion block (LSGB), corresponding to the level at which the LSG principally aggregate. METHODS Seventy-four consecutive subjects, including 31 women and 31 men, underwent LSGB either on the left (n = 31) o...

Slow synaptic transmission in frog sympathetic ganglia.

Bullfrog ganglia contain two classes of neurone, B and C cells, which receive different inputs and exhibit different slow synaptic potentials. B cells, to which most effort has been directed, possess slow and late slow EPSPs. The sEPSP reflects a muscarinic action of acetylcholine released from boutons on B cells, whereas the late sEPSP is caused by a peptide (similar to teleost LHRH) released ...

Hazards of carbon dioxide insufflation during thoracoscopy.

Hazards of carbon dioxide insufflation during thoracoscopy Editor,—I read with interest the review article on the anaesthetic implications of thoracoscopic sympathectomy. 1 When endobronchial anaesthesia is used, carbon dioxide may be insufflated only initially into the ipsilateral pleural space to augment lung collapse. In contrast , when a tracheal tube is used, carbon dioxide is insufflated ...
