(17) The larger nerve trunks of aganglionic bowel frequently contained myelinated axons and these have been observed within the myenteric plexus of normal rectum.
(18) In cases of Hirschsprung's disease with aganglionic segment confined to the rectum, even severe symptoms can subside considerably at some time or other usually before the age of 20.
(19) Aganglionosis is the result either of a defect in vagal neural crest migration or in the microenvironment over an extended area of the bowel and not just in the terminal aganglionic colon.
(20) In the control untreated tissues, 5-HT-like immunoreactive fibers were observed neither in the normoganglionic nor in the aganglionic regions.
Ganglionic
Definition:
(a.) Pertaining to, containing, or consisting of, ganglia or ganglion cells; as, a ganglionic artery; the ganglionic columns of the spinal cord.
Example Sentences:
(1) Following central retinal artery ligation, infarction of the retinal ganglion cells was reflected by a 97 per cent reduction in the radioactively labeled protein within the optic nerve.
(2) The Ca2+ channel current recorded under identical conditions in rat dorsal root ganglion neurones was less sensitive to blockade by PCP (IC50, 90 microM).
(3) A microdissection of the orbital nerves of the cat was made paying particular attention to the accessory ciliary ganglion.
(4) The diffuse reaction product seen in basement membranes of ganglion and nerve may also be artifact.
(5) No age differences were observed in DBH activity of any tissues examined or in the activities of any enzymes in the coeliac-mesenteric ganglion complex.
(6) The aim was to clarify the nature of their constituent cells, specifically the giant ganglion-like cells and spindle cells, and to discuss the implications for histogenesis.
(7) The death of retinal ganglion cells during development thus seems to serve 2 purposes: It provides for the quantitative matching of the ganglion cell population to the needs of its central projection fields, and, at the same time, it serves to selectively eliminate those cells whose axons project to inappropriate targets or to inappropriate regions within the correct target fields.
(8) Gangliogliomas are rare benign tumors of the central nervous system containing neoplastic ganglion and low grade glial cells.
(9) This suggests that many retinal ganglion cells continue to discharge in total darkness for long periods.
(10) The distribution and ultrastructure of lipopigments in the rat sympathetic, vagus and spinal ganglion neurons were studied in vivo and in vitro using fluorescence and electron microscopy.
(11) There is close correspondence between the two animals in terms of each of the identified cells or neuronal clusters in the ganglion, including the presence of the cell L10 (interneuron I) in A. brasiliana which makes synaptic connections comparable with those in A. californica.
(12) Four cases of a ganglion of the hip joint are reported.
(13) We postulate that an abnormality in retinal dopaminergic neurons, which are known to reduce light responsiveness of horizontal and ganglion cells, is the underlying pathophysiology of this clinical finding.
(14) Dorsal root ganglion (DRG) neurons cultured from neonatal rats contained high concentrations of protein kinase C (PKC).
(15) Hexamethonium, a ganglion blocker, and propranolol, a beta-adrenergic blocker, markedly inhibited the hyperglycemic response to stimulation of the lateral part of the PBD (LPBD).
(16) The results of the present experiments are consistent with the view that cyclic AMP may have a mediating role in the process of ganglionic transmission.
(17) PCP plus, 3,4-Diaminopyridine (3,4-DAP) decreased synaptic transmission block from post-ganglionic compound action potential (CAP) responses to supramaximal preganglionic stimulation.
(18) We suggest that the OH improved mainly because of the increase in MSA due to L-threo-DOPS, and that the drug may activate sympathetic outflow at a site proximal to the sympathetic ganglion.
