The ultrastructure of the pinealocytes of the golden mole (Amblysomus hottentotus), a blind subterranean mammal living in complete darkness, was examined and compared with that of pinealocytes of other mammals. On the basis of the presence of granular vesicles and glycogen granules, only one population of pinealocytes was found. Large mitochondria, ribosomes, lipid inclusions and scarce lysosomes were observed in the perikaryon. Numerous glycogen granules, often forming typical accumulations, were frequently found to be associated with typical vacuoles. An extraordinary large number of granular vesicles is characteristic of the golden mole pinealocyte. Phenomena of excretion of compound(s) stored in the granular vesicles were identified. Morphologically this is characterized by dissociation of its granular core in situ while its limiting membrane is preserved. The physiological significance of the secretory process characterized by the formation of these granular vesicles is discussed.
对生活在完全黑暗环境中的盲穴居哺乳动物金毛鼹（Amblysomus hottentotus）松果体细胞的超微结构进行了检查，并与其他哺乳动物的松果体细胞进行了比较。基于颗粒小泡和糖原颗粒的存在，仅发现了一群松果体细胞。在核周观察到大型线粒体、核糖体、脂质内含物和稀少的溶酶体。经常发现大量糖原颗粒，常形成典型的聚集物，并与典型的液泡相关。金毛鼹松果体细胞的特征是有大量颗粒小泡。鉴定了储存在颗粒小泡中的化合物的排泄现象。在形态学上，其特征是颗粒核心在原位解离，而其界膜保留。讨论了以这些颗粒小泡形成为特征的分泌过程的生理意义。
