Long-term stop-exposure inhalation study: lung inflammation markers in BALF. Rats were exposed for 13 weeks to AM or LA and evaluated at 1 day, 1, 3, and 18 months post-exposure. Values in legend represent target mass concentrations (mg/m3). Results show means ± SE of BALF macrophages, neutrophils, and lymphocytes, and concentrations of protein, LDH, and ALP (Alk Phos) in BALF supernatant (n = 8 rats/group). P < 0.05 †vs. all other groups; * vs. air control; # vs. LA 1.0; ‡ vs. AM 3.3; § vs. LA 3.3
