The Ultrastructure of Mouse Lung: The Alveolar Macrophage
Free alveolar macrophages of normal mouse lung have been studied in the electron microscope. The tissue was obtained from several young adult white mice. One other animal was instilled intranasally with diluted India ink 1(1/2) hours prior to the removal of the lung. Thin sections of the osmium-fixed, methacrylate-embedded tissue were examined either in an RCA EMU 2 electron microscope or in a ...
متن کاملThe Ultrastructure of Mouse Lung
The fine structure of the alveolar basement membrane of mouse lung was discussed on the basis of three electron micrographs. The basement membrane, i.e., the intercellular layer between endothelium and alveolar epithelium, was found to be of variable width. In its thin parts it appeared rather homogeneous, and did not reveal well defined layers of fibrils. In its thicker portions, some of which...
متن کاملThe Ultrastructure of Mouse Lung General Architecture of Capillary and Alveolar Walls
The general architecture of capillary and alveolar walls of the mouse lung was studied by means of the electron microscope. In order to minimize tissue damage and to improve the cutting properties of embeddings, several modifications in the tissue processing methods were adopted. These modifications were: fixation by infusion, a prolonged time of dehydration, of impregnation, and of polymerizat...
متن کاملThe Effects of Amiodarone of Rabbit Lung Alveolar Cells
Purpose: The effects of Amiodarone on lung tissue and morphologic changes of alveolar cells. Materials and Methods: in this study, we used 21 mature male rabbits and they were divided into control and two experimental groups. Daily 80 mg/kg amiodarone was injected intra peritoneally to the experimental animals for one or two weeks. The control group received normal saline the same dose as amio...
متن کاملUltrastructure of intercellular junctions in the freeze fractured alveolar-capillary membrane of mouse lung.
I ntercellular junctions are specialized regions of contact between the apposed membranes of adjacent cells, which allow cells to interact with each other, and to form structures of higher order. While at least 4 different types of intercellular junctions have been recognized in mammalian tissues,1 in the case of the alveolar-capillary membrane we shall be concerned with only 2 types: the tight...
