In previous studies, we found that endotracheal administration of beryllium oxide (BeO) produced cell-mediated immunity and granulomatous lung disease in strain 2 but not strain 13 guinea pigs. This report describes phenotypic and functional studies of bronchial lavage cells from both guinea pig strains after BeO exposure. In BeO-treated strain 2 animals, the percentage of T (ER+)3 lymphocytes was significantly (p less than 0.05) elevated above normal by 2 weeks after BeO exposure, while T lymphocytes were not increased in strain 13. Giant cells containing crystalline material in fused, coalesced phagolysosomes were observed in treated animals of both strains. BeO-exposed strain 2 alveolar macrophages (AM) demonstrated enhanced killing of Listeria monocytogenes and enhanced chemiluminescence, while AM of strain 13 had responses below controls. Findings support the presence of BeO-induced cellular immunologic activity in strain 2 animals and, on the other hand, suggest BeO toxicity to lavage cells in strain 13.
