The Effect of Incomplete Fixation of Elastin on the Appearance of Pulmonary Alveoli
Journal of Biomechanical Engineering, 1982Pulmonary alveolar geometry in histological sections prepared by quick-freezing the lung, with freeze-substitution of ice, fixation of the dry lung with osmium tetroxide in nonaqueous and nonpolar solvent and celloidin embedding is remarkably different from the geometry seen in preparations made by instilling aqueous aldehyde or osmium tetroxide ...

Distribution of Inhaled Metal Oxide Particles in Pulmonary Alveoli
Archives of Internal Medicine, 1971The phagocytic response of alveolar cells is a significant factor in determining the pulmonary distribution and fate of inhaled, insoluble particles. The type I alveolar epithelium and alveolar macrophage readily phagocytized inhaled nickel monoxide and chromic oxide particles with 80% and 91%, respectively, of alveolar deposits being found in ...

Formation of Pulmonary Alveoli and Gas-Exchange Surface Area: Quantitation and Regulation
Annual Review of Physiology, 1996New morphometric procedures allow selection of alveoli for analysis in an unbiased manner and then to determine the volume of individual alveoli. The latter, together with the easily measured lung volume, allows the calculation of alveolar number. These new techniques have greatly increased the rigor of the study of the formation of alveoli and the ...

Effects of Ozone on Cell Renewal in Pulmonary Alveoli of Aging Mice
Archives of Environmental Health: An International Journal, 1971Groups of aging male mice were exposed to different concentrations of ozone (O3) for six hours. Following exposure, the animals were killed at intervals of 1, 24, 48, and 72 hours. Prior to killing, cells synthesizing DNA were labeled with tritiated thymidine.

Invited Review: Pulmonary alveoli: formation, the “call for oxygen,” and other regulators
American Journal of Physiology-Lung Cellular and Molecular Physiology, 2002The lung's only known essential function is to provide sufficient alveolar surface to meet the organism's need for oxygen and elimination of CO2. The importance of the magnitude of alveolar surface area (Sa) to O2uptake (V˙o2) is supported by the presence among mammals of a direct linear relationship between Sa and V˙o2.
