The
refractile lithocytes are roughly spheroidal with a diameter of about 10 [micro]m and a calculated cellular volume of about 525 [micro][m.sup.3] in both larvae and adults.
Cytology findings consist of fat droplets containing radially arranged
refractile needle-shaped crystals in a background of inflammatory cells, including lymphocytes, histiocytes, and multinucleated giant cells, with or without calcifications.
Microscopic examinations showed fresh hAECs as large,
refractile round cells with great capacity to adhere to the plastic surfaces.
Numerous fungi in the form of spores and
refractile nonseptate hyphae were seen (Figures 5).
On microscopic examination of negatively stained smears all oocysts appeared as unstained, strongly
refractile, and round to oval structures against dark coloured background.
Monolayers treated with high concentrations of extracts exhibited holes formation with retraction of cells even attached and generated round cells grouped and
refractile intracytoplasmic granulations, in addition to cell detachment.
Under the microscope, the colorless live cells looked small, round, and
refractile while the nonliving cells appeared swollen, big, and dark blue.
As shown in Figure 2(a), when DU145 cells were treated with CXCL12, the percentage of spread cells decreased significantly and
refractile morphological changes and cell detachment were noticed; while some cells appeared round, other cells became elongated and spindle-shaped, resembling mesenchymal cells (Figure 3(a)).
The kinetoplast was a small
refractile, stained densely blue-violet and situated next to the basal body.
It can, very rarely, produce a retinopathy characterised by bilateral fine intraretinal
refractile opacities, hypopigmented lesions at the level of the RPE, and macular oedema (Figure 9, page 34).
Some of the cells showed
refractile perinuclear cytoplasmic round bodies.
