| Method |
Abstract: "Resident AM [Alveolar Macrophage] from CD rats, Syrian golden hamsters, cynomolgus monkeys, and nonsmoking, healthy human volunteers were harvested by standard bronchoalveolar lavage procedures. Morphometric analysis of alveolar macrophage was performed using a flow cytometer that generates volume signals based on the Coulter-type measurement of electrical resistance." |

Abstract: "Comparatively, the AM [Alveolar Macrophage] from monkeys (15.3 ± 0.5 µm, n = 7) and human volunteers (21.2 ± 0.3 µm, n = 10) were larger than those from rats and hamsters." P.1262 middle column bottom paragraph: "Table 2 summarizes the morphometric data obtained by selective Coulter-type flow cytometric analysis of unfixed cells in suspension. The cell sizes of hamster and rat AM were not statistically different from each other. Comparatively, the AM from monkeys and nonsmoking, healthy human volunteers were significantly larger (p<0.05) than those from rats and hamsters. The AM from human volunteers were significantly larger (p<0.05) than those from all other species studied, corresponding to a roughly 4-fold larger cell volume of human AM compared to hamster and rat AM." |
