The ultrastructure of annulate lamellae in the pancreatic exocrine cells of rats starved for 3-42 days was studied. Annulate lamellae were rarely encountered in the pancreatic exocrine cells of control rats, but their incidence and size of stack was increased in those of starved rats depending on the duration of starvation, despite marked ultrastructural changes in these cells. Annulate lamellae were located in the para- or infranuclear cytoplasm of the cells and most of them were continuous with the relative normal rough endoplasmic reticulum. A close apposition in parallel was often found between the annulate lamellae and the outer nuclear envelope and occasionally pores in line with those of the nuclear membrane were observed in the lamellae of rough endoplasmic reticulum in 35- and 42-day-starved rats. An unequivocal continuity between the annulate lamellae and the nucleus and/or rough endoplasmic reticulum in pancreatic exocrine cells might be related to their origin and function.
对饥饿3 - 42天大鼠胰腺外分泌细胞中环孔板层的超微结构进行了研究。在对照大鼠的胰腺外分泌细胞中很少见到环孔板层，但在饥饿大鼠的细胞中，其发生率和堆叠大小随饥饿时间延长而增加，尽管这些细胞有明显的超微结构变化。环孔板层位于细胞的核旁或核下细胞质中，大多数与相对正常的粗面内质网相连。在35天和42天饥饿大鼠的粗面内质网板层中，常发现环孔板层与外核膜平行紧密相邻，偶尔还观察到与核膜孔一致的孔。胰腺外分泌细胞中环孔板层与细胞核和/或粗面内质网之间明确的连续性可能与其起源和功能有关。
