Nuclei of the Schwann cells were heterochromatic and pyknotic with prominent cytoplasmic eosinophilia.
10 fields for each section were investigated and counted for total cells in field and cells that show degenerative signs such as pyknotic nuclei for cerebral cortex and hippocampus and flattened atrophied cells in substantia nigra.
Some of their nuclei were pyknotic: a crescent-shaped chromatin and cytoplasm material was distinguished as being of a characteristic feature of apoptosis (Fig.
In the submandibular glands, changes in the atrophic sinuses, from serous acinus and pyknotic nuclei, were significant in some gland epithelial cells.
Nucleated superficial cells and anucleate superficial cells presented a polygonal shape, with presence of an intact or pyknotic nucleus in the latter.
Sections from STZ-diabetic mice displayed damaged islets, represented by cytoplasmic vacuolations, pyknotic nuclei and atrophied islets of Langerhans (Figure 6B).
In addition to the chromatin condensation that was shown in almost all cells exposed to the agent, a pyknotic nucleus formation was detected and the micronuclei of the treated cells were raised in number (Figure 2b).
In Group II, the lesions were mild and were only observed in the cerebellum and frontal and parietal cortexes, and the lesions consisted of neuronal necrosis as evidenced by the presence of small cell bodies with an eosinophilic and angular cytoplasm and pyknotic nucleus.
Liver sections in the CP-treated group showed periportal leucocyte infiltration, dilation in sinusoidal space (thick black arrow), focal necrosis with pyknotic nuclei, hepatocyte vacuolation, hyperplasia in Kuppfer cells (narrow black arrow), congestion, granulomatous formation (thick black arrow), and hemorrhage in the central vein (narrow white arrow) (C).
The surviving cells after 48 h were senescent with pyknotic cell nuclei (Figure 1).
Ductular epithelium was segmentally denuded and necrotic, characterized by hypereosinophilic cytoplasm with pyknotic to karyorrhectic nuclei.
