Effects of CGUFP exposure on pulmonary inflammation. (A) BALFs were collected and cell differentials obtained. *p < 0.05, **p < 0.01, and ***p < 0.001. (B) Lymphocyte populations in the lungs of rats exposed to CGUFP were quantified by flow cytometry using antibodies specific for the indicated cells after gating on lymphocytes (CD4 and CD8) or non-lymphocytes (DC). Mac indicates macrophages; Neu: neutrophils; Lym: lymphocytes; Eos: eosinophils. n = 4-6 animals/group. *p < 0.05 vs. air and #p < 0.05 vs DCB50.
