Fig. 3. Electron microscope observation of heterophil ultrastructure in green sea turtles (Chelonia mydas) studied in Taiwan. All cells were stained with uranyl acetate and lead citrate. H: heterochromatin; U: euchromatin; I: first type of granules; II: second type of granules; M: mitochondria; R: rough-surfaced endoplasmic reticulum (RER). A: the first type of granules were generally homogeneous in electron density, and a second type of granules were more electron-dense, fewer in number and comparable to the first type of granules in size, B: the two types of granules distributed unevenly within the cytoplasm.
