| Abstract: | Genesis and function through histo and cytology and cyto-chemistry are researched in midgut gland of Penaeus chinensis at larval stage. The results show that 2 pairs of midgut gland diverticula protrude from the midgut at N4--5, of which the first one degenerates gradually and disappears at M3, while the second one would develop into the midgut gland in adult. The midgut gland cell differentiation occurs at Z2. There are 4 types of cells, i. e., embryonic cell (E-cell), fibrillar cell (F-cell), blister cell (B-cell) and resorptive cell(R-cell). The epithelial cells of gland show no difference during larval development. The proportion of nucleus and cytoplasm in E-cell is high, but organelles are not rich. E-cell has obvious ability of division. In F-cells plenty of rough endoplasmic reticulum and zymogen can be observed. And in F-cell there is ACP activity at microvilli obviousely. On the top of B-cell, pinocytotic phenomenon can be observed distinctly, and there exist some small vesicles and large digestive ones. Because of different physiological states in the cells, ACP activities occur at different sites obviously. The early R-cells are very rich in mitochondria and smooth endoplasmic reticulum with plenty of fatty granular and glycogen. |
