(12) Later, the astroglial processes of regenerated glia limitans showed very infolded surfaces and numerous filaments inside of them.
(13) These studies suggest that certain perineuronal glia are transformed into reactive astrocytes in areas of ischemic neuronal necrosis, although current data are insufficient to determine if the transforming cells are astrocytes, light oligodendrocytes, or intermediate glia.
(14) Glia occupied 25% of the neuropil within 1 mm of the dorsal root-transplant interface, but only 6% of the neuropil 1-2 mm from the interface.
(15) In the presence of beta-alanine (10(-3) M), a substrate specific inhibitor of high-affinity GABA transport into glia, tritiated GABA was accumulated by a high-affinity uptake system into myenteric ganglia and a subpopulation of mucosal cells.
(16) It was of interest to determine whether this class of glia is essential to the normal cytoarchitectural development of the neural retina.
(17) Proliferation of glia cells and decrease of nerve cells were also noted.
(18) Diverse molecules rapidly traverse the periaxonal sheath and a fraction of them enters the axons from glia or the glia from axons.
(19) Both types of cells are closely associated with processes of radial ependymal glia cells, which perhaps orient their migratory pathways.
(20) In addition, during regeneration, optic nerve glia express large amounts of the 50 kDa cytoskeletal protein, which they ordinarily express at only minimal levels.
Neuroglia
Definition:
(n.) The delicate connective tissue framework which supports the nervous matter and blood vessels of the brain and spinal cord.
Example Sentences:
(1) In old animals, folic acid increased in neurons, neuroglia and some nerve cell processes; the folate enzyme was markedly decreased in neurons and increased neuroglia NADH2-cytochrom-C-reductase activity was strongly positive in nerve cells in young and old animals.
(2) Lesser staining was seen in neuroglia, ependymal, and choroidal cells.
(3) Vascular effects occur at lower dose levels but after a longer latent period than effects mediated through damage to neuroglia.
(4) Cerebella treated with cAMP antisera, however, showed immunoreactivity in Purkinje cells, granule cells, and Golgi cells in addition to neuroglia in cortex and deep nuclei.
(5) Intermediate structure may be either a connective tissue or neuroglia, or (seldom) other neuronal cells.
(6) Participation of Na,K-ATPase in the regulatory mechanisms of the neuron-neuroglia relations is discussed.
(7) The paper describes the histological pattern of 6 neurogenic tumors of the stomach in which all the elements of the nervous system have been found: ganglionic cells, neuroglia, and nerve stems.
(8) This has prompted us to study the drug effect on neuroglia cells in corpus callosum and gyrus cinguli.
(9) The data indicate that taurine is being released from excitable cells rather than neuroglia and may therefore have some neurotransmitter-like role in the cerebellum.
(10) The tissue of the CNS (central nervous system) is composed of neurons and neuroglia.
(11) The significance of these synapses is considered as part of a dynamic pattern of relations between neurons and neuroglia: transmission of a rapid message leading to an adjustment of the oligodendroglial cells to the functional changes of the neurons of which they are satellites.
(12) In addition to neuroglia, some endothelial cells were labeled after day 9.
(13) Drawings of gross and microscopic thalamic structures were made at 4 planes and computer-digitized to provide 7 measures: total thalamic area at planes A 7.5 and A 8.5; counts of neuroglia, small neurons (31-100 microns2) and large neurons (101-1000 microns2); area of neuroglia, small neurons and large neurons.
(14) Vascular neuroglia is composed of glycogen and mitochondria-laden, interlocked cells that form an open meshwork in the hemocoelic spaces of the brain.
(15) A morphological, karyometric, and quantitative study of cerebral neuroglia and endothelial cells of blood capillaries was done in cirrhotic and in hepatosplenic schistosomotic human autopsied cases.
(16) In addition, within the Alzheimer's brains studied, the nuclei of select neurons and a small number of microglia were also immunopositive for heparan sulfate glycosaminoglycan in contrast to controls, where nuclei and neuroglia were immuno-negative.
