长蛸唾液腺和消化腺的组织学与组织化学研究

HISTOLOGICAL AND HISTOCHEMICAL STUDIES ON SALIVARY GLANDS AND DIGESTIVE GLANDS OF Octopus variabilis SASAKI

以组织学和组织化学方法 ,研究了长蛸的唾液腺和消化腺。前唾液腺腺细胞含团状糖蛋白性质的分泌颗粒。后唾液腺有两种腺管 ,I型腺管由I型腺细胞和黏液细胞组成。I型腺细胞含团状分泌颗粒及丰富的RNA ,具脂酶活性;黏液细胞分泌酸性黏多糖。II型腺管的腺细胞内含一桃形丝状物。肝细胞含大量的分泌颗粒 ,呈现强的蛋白酶及弱的非特异性酯酶和脂酶活性。胰脏腺细胞呈非特异性酯酶和弱的蛋白酶和脂酶活性。

The salivary glands and the digestive glands were studied with histological and histochemical methods. The gland cells of the anterior salivary glands contain secretory granules in groups which are proteoglycan. There are two kinds of tubules in the posterios salivary glands, the tubule I consists of gland cell I and mucous cells. The gland cell I contains secretory granules in groups and abundant RNA, and shows lipase activity. The mucous cells secrete acid mucopolysaccharides. Each gland cell of the tubule Ⅱ contains a peach like body. The liver cells are piled up secretory granules, and show activity of strong proteinase, weak non specific esterase and lipase. The pancreas cells show activity of non specific esterase, weak proteinase and lipase.
