Lung lavage neutrophils and protein response in PTFE-fume adapted and non-adapted F-344 rats. Adapted rats were exposed for 3 days for 5 min. each day to PTFE fumes, followed on Day 4 by a 15-min. exposure. Non-adapted rats were sham-exposed on 3 days for 5 min. and PTFE-fume exposed for 15 min. on day 4. Control rats were sham-exposed on all days for the same duration. Mean particle size was ~20 nm at concentration of 5×105 part/cm3 (~50 μg/m3).
