Abstract | The relationship between alveolar macrophages and spheroid alveolar epithelial cells was studied with the electron microscope after injection of squid-ink solution into the trachea of the mouse. At 20 hours after injection of squid-ink solution slight degeneration was evident in alveolar macrophages with sepia-melanin particles being phagocytized with partial digestion by lysosmes. Furthermore, hardly any changes were seen in mitochondria and inclusion bodies of the spheroid alveolar epithelial cells. In contrast, at one week after injection of squid-ink solution, almost all alveolar macrophages were degenerated with destruction of the ectoplasm in which the ingested sepia-melanin particles were digested by lysosomes into fine particles, and the mitochondria of spheroid alveolar epithelial cells were degenerated and the inclusion bodies were hardly formed. At three weeks after injection of squid-ink solution, alveolar macrophages as well as speroid alveolar epithelial cells showed almost complete recovery of functional structure. As the phagocyte in the alveolar space, neutrophile leucocytes were also observed in addition to the so-called alveolar macrophage. |
