In an effort to review ultrastructural features of cells in the kidney of a male rat, transmission electron microscopy was used to study ultrathin sections.
One light cell in a collecting tubule contained a 2.3-microns long linear array of electron-dense asymmetric structures in a granular zone of greater electron density than the general cytoplasm. This inclusion body could be interpreted to consist of a parallel array of 100-150-nm x 24-nm electron-dense rodlets, or a parallel array of 100-150-nm x 67-nm tubules. The inclusion showed no association with any cell organelle. The origin, chemical nature, frequency of occurrence, and functional significance of this inclusion are unknown.
Although this inclusion body somewhat resembles previously described inclusions or granules, the differences in dimensions, frequency, and relation to other cell structures suggest it is a new observation.
为了观察雄性大鼠肾脏细胞的超微结构特征，采用透射电子显微镜对超薄切片进行研究。
在一条集合小管中的一个亮细胞内，在一个电子密度高于一般细胞质的颗粒区中，有一个长2.3微米的电子致密不对称结构的线性阵列。这个包涵体可以被解释为由100 - 150纳米×24纳米的电子致密小杆平行排列组成，或者由100 - 150纳米×67纳米的小管平行排列组成。该包涵体与任何细胞器均无关联。这种包涵体的起源、化学性质、出现频率及功能意义均未知。
尽管这种包涵体在一定程度上类似于先前描述的包涵体或颗粒，但在尺寸、频率以及与其他细胞结构的关系方面存在差异，这表明它是一项新的观察发现。
