The cellular localization of the molecular forms of acetylcholinesterase was explored in chick sympathetic neurons and in mouse T28 cells (neuroblastoma X sympathetic ganglion cell hybrids) using the reversible, poorly lipid-soluble inhibitor of acetylcholinesterase, BW284C51, to protect cell surface activity while inactivating cytoplasmic activity with DFP, an irreversible, lipid-soluble inhib...

The inputs from sympathetic ganglia have been known to be involved in the pathophysiology of various painful conditions such as complex regional pain syndrome, cancer pain of different origin, and coccygodynia. Sympathetic ganglia blocks are used to relieve patients who suffer from these conditions for over a century. Many numbers of local anesthetics such as bupivacaine or neurolytic agents su...

Retrograde tracing was used to determine the locations of sympathetic nerve cells whose axons project to the stomach, small intestine, caecum, proximal colon, distal colon and spleen of the guinea-pig. Projections from prevertebral ganglia were organotopically arranged within and between ganglia. The cranially located coeliac ganglion provided the major input to proximal gut regions; the distal...

Saguinus niger popularly known as Sauim, is a Brazilian North primate. Sympathetic chain investigation would support traumatic and/or cancer diagnosis which are little described in wild animals. The aim of this study was to describe the morphology and distribution of sympathetic chain in order to supply knowledge for neurocomparative research. Three female young animals that came death by natur...

Studies of the stellate ganglion and middle cervical ganglion indicate that sympathetic efferent nerve activity can be modified by peripheral excitatory inputs and that these neural connections may function as pathways for a peripheral reflex at the level of the thoracic sympathetic ganglia. This excitatory synaptic input could have a soma in either the central or the peripheral nervous system....

The primordia of the sympathetic trunk ganglia were traced on serial sections of 10 embryos at stage 13 (32 postovulatory days). It was found that in all embryos, these primordia were present in the thoracic level T4 to T9 and they appeared as scattered aggregates of cells lying dorsally and laterally to the dorsal aortae.

Dai and colleagues (Dai X, Galligan JJ, Watts SW, Fink GD, and Kreulen DL. Hypertension 43: 1048-1054, 2004) found that endothelin (ET) stimulated O2- production in sympathetic ganglion neurons in vitro by activating ET(B) receptors. The objective of the present study was to determine whether activation of ET(B) receptors in vivo elevates O2- levels in sympathetic ganglia. Because ET(B) recepto...

Local rates of glucose utilization in the superior cervical, cardiac, and coeliac ganglia were measured by means of the autoradiographic 2-deoxy-D-[14C]glucose method in male spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY), 32-34, 46-48, and 78-87 days old. Brain glucose utilization was examined in 78-87-day-old SHR and WKY. At 32-34 days (at which time mean arter...

The aim of the present study was to establish the origin of the motor, autonomic and sensory innervation of the L1-L2 segment of the porcine longissimus dorsi muscle (LDM), in order to provide morphological basis for further studies focusing on this neural pathway under experimental conditions, e.g. phototerapy and/or lateral electrical surface stimulation. To reach the goal of the study, multi...
