The Ultrastructure of Tongue Mast Cells in Bombina orientalis


This study was carried out to observe the ultrastructure of tongue mast cells in frog, Bombina orientalis. In the light microscopy, mast cells were round, oval, spindle-like and irregular shape and occasionally had one or more tail-like long cytoplasmic processes. Mast cells had many red granules stained with toluidine blue in the cytoplasm. In the electron microscopy, mast cells had membrane-bounded granules and poorly developed organelles. The granules were composed of two parts, low and dense electron density. In high magnification the dense part in the middle region of granule had honey comb-like crystalline structure.
