Electron Microscopic Study of the Mast Cells of the Bat Stomach

Mask cells are distributed in the animal tissue, The bat subject has not been studied with the electron microscope, The material was fixed in 2.5% phosphate buffered glutaraldehyde for 24 hours at $4^{\circ}C$ and then post-fixed in phosphate buffered 1% osmium tetroxide for 2 hours at $4^{\circ}C$ and then the cleared tissues were embedded in Epon. The mast cell has numerous cytoplasmic processes projecting into the surrounding connective tissue. In general, the cytoplasmic granules showed ovoid, round, lunal or irregular shape, most of them were fine particulate substructure in texture. Especially, the granules was enclosed by the lamella structure.
