From: The role of pro- and anti-inflammatory responses in silica-induced lung fibrosis
Lactate dehydrogenase (LDH) activity, total protein content and neutrophil numbers in bronchoalveolar lavage of Sprague-Dawley (SD) rats (A-C) and NMRI mice (D-F) after intratracheal instillation of saline or silica particles (2.5 or 25 mg/ g lung). Bars represent means +/- SEM of 5 to 7 animals. Significant differences between treated animals and controls: *P < 0.05, **P < 0.01, ***P < 0.001 (Student-Newman-Keuls multiple comparison test). Please note the different scales between mice and rats for LDH and neutrophils.
