The whorls of rough endoplasmic reticulum (rER) in the exocrine pancreatic cells of starved newts and clawed toads were examined by a freeze-fracture technique. The whorl appeared to be roughly ovoidal in shape and composed of tightly packed, narrow cisternae arranged like the layers of an onion. The clusters of interdigitating projections of the cisternal membranes were located at several places on the whorl. Some of these projections extended to the vesicular rER around the whorl. The fenestra-like, raised or hollowed craters were seldom seen on the fractured membrane faces of the whorls in the exocrine pancreatic cells of the starved newts.
采用冷冻蚀刻技术对饥饿蝾螈和爪蟾外分泌胰腺细胞中的粗面内质网（rER）的涡状结构进行了研究。该涡状结构呈大致卵形，由紧密排列的狭窄池组成，排列方式类似洋葱的层状结构。池膜相互交错的突起簇位于涡状结构的多个位置。其中一些突起延伸至涡状结构周围的泡状粗面内质网。在饥饿蝾螈外分泌胰腺细胞的涡状结构的断裂膜面上很少见到窗孔样、凸起或凹陷的坑。
