猪肾集合小管的细胞构筑及超微结构

The Cellular Architectures and Ultrastructures of Pig Kidney Collecting Duct

目的 对猪肾集合小管的细胞组成以及超微结构进行研究。方法 应用光镜、电镜技术。结果 集合小管是由主细胞和闰细胞组成。主细胞随着集合小管向髓质内带移行过程中超微结构发生了变化。闰细胞的特点是基质密度高 ,线粒体发达。闰细胞有两种类型 ,即A型和B型。本文对这两种类型闰细胞的分布及超微结构进行了描述。

Objective To study the cellular components and ultrastructures of pig kidney collecting duct. Methods Light and Electron Microscopy were used in this study. Results The results provide the facts that collecting duct consists of principal cells and intercalated cells. The principal cells were changed in their ultrastructures when their locations were changed along the medullary ray. Intercalated cells, as the predominant component, could be divided into two types,type A and type B, according to their ultrastructural differences. They could be observed in the collecting ducts in IC ,OC and OM. Conclusions The cellular components and ultrastructures of pig kidney collecting duct were nearly same as that of human kidney collecting duct.
