Production of cytokines and chemokines caused by PHMG-P instillation in the mouse lung. Lung homogenates from vehicle-exposed mice or PHMG-P-treated mice at 7, 14 and 28 days after exposure were collected, and the concentrations of IL-6, TNF-α, CCL2 and CXCL1 in supernatants were determined by ELISA. Vehicle-treated (N = 3), PHMG-P-treated groups (N = 5) mice. (*P<0.05; **P<0.01)
