Nerve endings in human sympathetic ganglia
American Journal of Anatomy, 1981AbstractForty‐eight human sympathetic ganglia from 22 sympathectomies were examined ultrastructurally after one of three different fixations: (1) glutaraldehyde + osmium tetroxide, (2) glutaraldehyde + potassium dichromate + osmium tetroxide, or (3) potassium permanganate.Three different kinds of synapsing nerve ending could be identified after all ...

γ-Aminobutyric Acid Uptake by Sympathetic Ganglia
Nature New Biology, 1972EXOGENOUS γ-aminobutyric acid (GABA) accumulates against a concentration gradient in isolated mammalian nervous tissue1–3 and mixes with GABA stored in the tissue4. Thus, neurones which use GABA as an inhibitory transmitter might be identified by locating sites of accumulation of radioactively-labelled GABA using autoradiography5–7, assuming that ...

Neural—immune interactions in sympathetic ganglia
Trends in Neurosciences, 1993Effects of immune cytokines on neuronal gene expression have recently been examined in cultured superior cervical (sympathetic) ganglia, a widely used model system for the study of neurotransmitter plasticity. Following deafferentation and explantation into culture, interleukin-1 causes an up-regulation of the neuropeptide substance P as well as of ...

Late Discharges in Dog's Sympathetic Ganglia
Canadian Journal of Physiology and Pharmacology, 1972In the dog a preganglionic stimulation at a high stimulus frequency for 10–15 s elicited a two-wave response, early and late responses in the perfused ear (vasoconstriction), as well as early and late contractions in the nictitating membrane. Both the late contraction and the late response could be aborted by cooling the superior cervical ganglion ...

Neuropathology of human sympathetic autonomic ganglia
Microscopy Research and Technique, 1996The neuropathologic alterations which underlie autonomic nervous system dysfunction in aging and in a variety of diseases have been systematically examined in the sympathetic ganglia of a series of 347 autopsied adults and in a review of previously published studies.
