The fine structure of the stratified lamina fenestrata of the mouse glomerulus was described in detail in both transmission and scanning electron microscopy. We propose to name the extremely developed structure of the stratified lamina fenestrata as the alveolus endothelialis. It consists of numerous small irregular spaces partitioned by thin cytoplasmic processes. Individual spaces communicate with each other through the fenestra surrounded by the cytoplasmic partitions. This structure occurs not only on the basal lamina but also on the perikaryal portion of the endothelium. The constant appearance of the alveolus fenestratus without association of any pathological or degenerative changes suggests that this structure represents a certain general and fundamental feature of the fenestrated endothelial cell. Possible mechanisms for the genesis of this structure are briefly discussed.
利用透射电子显微镜和扫描电子显微镜对小鼠肾小球分层有孔板的精细结构进行了详细描述。我们建议将分层有孔板极度发达的结构命名为内皮肺泡。它由许多由薄细胞质突起分隔的小不规则空间组成。各个空间通过被细胞质分隔包围的窗孔相互连通。这种结构不仅出现在基膜上，也出现在内皮细胞的核周部分。无任何病理或退行性改变相关的有孔肺泡持续出现，表明这种结构代表了有孔内皮细胞的某种普遍和基本特征。本文简要讨论了这种结构的可能形成机制。
