摘　　要：应用常规电镜技术对10只大鼠的附睾进行了超微结构观察。附睾上皮各型细胞的超微结构除主细胞外均无明显的节段性区别。各段主细胞均具有分泌细胞和吸收细胞的超微结构特征。但近段附睾的主细胞偏重呈现吸收细胞的特点,而远段主细胞则偏重显示分泌细胞的特征。此外,发现在有的晕细胞外面包绕一个具长突的细胞。于附睾尾段少数亮细胞的基部见到类结晶体结构。管周组织内发现存在有窗孔毛细血管。本文对上述有关结构的意义作了简单的讨论。By the routine electron microscopy the ultrastructure of the epididymis of 10 rats is studied.Except the principal cells,there is no significant difference in the ultrastructure of the other cell types of the epididymal epithelium between segments.The principal cell shows the ultrastructural characteristics of secretion and absorption.However,the ultrastructural characteristics of the principal cells in the proximal epididymvs show more tendency to absorbent and that in the distal epididymis show more tendency to secretory.Further-more it is observed that some halo cells are surrounded by small cells which possess long processes.Some or a few number of clear cells in the caudal epididymis contain some crystaloid inclusions in their basal cytoplasm.The presence of the fenestrated capillary in the peritubular tissue is also found.The meaning of the ultrastructures mentioned above is discussed.
