| Often the fractured platelike secretions and crystalloid forms were associated with refractile spherical particulate debris. |
| Viewed using phase microscopy, live cells will appear bright and refractile, whereas dead cells will appear somewhat larger and stained dark with eosin dye. |
| Numerous sheet-like refractile and strongly polarizable particles are present within the histiocytes. |
| Yeast cells can be mistaken for red blood cells since they have a double refractile wall which may simulate the donut appearance of red cells. |
| As the colony increases, the granular character becomes more marked, until it seems to be made up of highly refractile granules, like a mass of particles of glass. |
| Each ommatidium contains six to eight sensory receptors arranged under a cornea and refractile cone and is surrounded by pigment cells, which adjust the intensity of light. |
