Abstract

Abstract

The mast cells in hindgut, head kidney and spleen of H apalogenys nitens were investigated by using transmission electron micro scopy.The results showed that mast cells possessing cytoplasmic processes or surface folds were found in all the organs studied, but were especially abundant in hindgut and head kidney.The mast cells perhaps could be classified into two major subtypes by the special substructures of their characteristic cytoplasmic granules and referred to as type Ⅰ and type Ⅱ mast cells.The cytoplasmic granules with tiny particulate substructure were characteristic of the type Ⅰ mast cells, which distributed mainly in the lamina propria and submucosa layers of the hindgut and in the connective tissues of the head kidney.And the type Ⅱ mast cells locating only in the connective tissues of the head kidney and spleen were characterized by their cytoplasmic granules exhibiting a variety of crystalline substructural patterns, such as whorl, thread, honeycomb, particulate, amorphism, and mixture of these substructural patterns.The degranulation was also found in the two subtypes of mast cells.Our results demonst rate that numerous mast cells containing characteristic cytoplasmic granules with delicate special substructures are present in hindgut, head kidney and spleen of H apalogenys nitens.
