幼龄皱纹盘鲍唾液腺和消化腺的超微结构与组织化学

Ultrastructure and Histochemistry of the Salivary and Digestive Glands of the Juvenile Abalone Haliotis discus hannai

以透射电镜观察和组织化学方法研究了 45日龄皱纹盘鲍的唾液腺和消化腺。唾液腺由粘液细胞和纤毛细胞组成 ,粘液细胞含发达的粗面内质网和大量的粘原颗粒 ,分泌中性和酸性混合粘多糖。消化腺由消化细胞和嗜碱性细胞组成 ,消化细胞呈现活跃的内吞和细胞内消化 ,并具蛋白酶和非特异性酯酶活性。嗜碱性细胞含发达的粗面内质网和大量含铁的折光小体 。

The salivary and digestive glands of 45 day\|old abalone Haliotis discus hannai Ino were examined with a transmission electron microscopic and histochemical techniques. The salivary gland consisted of mucous cells and ciliated cells. The mucous cells contained well\|developed rough endoplasmic reticulum and a number of mucous pro\|granules, and secreted neutral and acid mucopolysaccharide. The digestive gland consisted of digestive cells and basophilic cells. The digestive cells showed active endocytosis and intracellular digestion, and also proteinase and non\|specific esterase activity. There were well\|developed rough endoplasmic reticula and many rafractile spherules containing iron in the basophilic cells. The spherules had low electron density.
