We introduced the term massive submucosal ganglia to refer to submucosal ganglia containing at least 20 perikarya
in 1 histologic section.
(1971) Lipid composition of nerve cell perikarya
. Brain Res.
In addition, argyrophilic tangles were observed in perikarya
and proximal neurites of neurons as far distal as the lumbar and sacral cord areas (42).
We determined by stereological methods the relation surface/volume (Sv) and the volumetric density (Vv= total surface area / surface of perikarya
circumscribed in every field) (Weibel and Gomez, 1962; Weibel, 1979; Mandarimde-Lacerda, 1998,1999).
Coen, "Brainstem projections to the medial preoptic region containing the luteinizing hormone-releasing hormone perikarya
in the rat.
It decreased during the night and was accompanied by increase in the area of AVP perikarya
but not by changes in the number of synapses .
Abnormally phosphorylated NFs accumulate in the perikarya
and the phospho-NF aggregates can thus become cytotoxic by the enduring impairment of axonal transport of NFs [226, 227].
The cytoplasm of the perikarya
, as described by Bullock and Horridge (1965), is so scanty it is difficult to visualize in ordinary preparations.
In particular, a MAT concentration of Cd supplied damaged external pyramidal neuron, as exhibited by a typically argyrophilic dark neuronal perikarya
and often by a shrunken and folded appearance compared with little or no damage in controls (Figure 2d,h).
A single brain showed subtle A[Beta] punctate aggregates in the neuronal perikarya
in the absence of extracellular deposits of A[Beta].
The present study was therefore designed to define chemical expression of somatostatin in the sympathetic perikarya
innervating the porcine stomach prepyloric area in the physiological state, during acetylsalicylic-acid-induced gastritis and experimentally induced hyperacidity and following partial stomach resection.
All MAP-2 immunoreactive processes that emerged from the cell perikarya
(first level processes) were not considered in the discrimination procedures so that axons and axon hillock were not included in the measurements.
