Concentrations of the polymorphonuclear leucocytes (PMN) mobilizer granulocyte colony-stimulating factor (G-CSF) in the supernatants of the lung homogenates were determined by enzyme-linked immunosorbent assay (ELISA). G-CSF concentrations were increased significantly in the small beads (SB) group at day 1 compared to the large beads (LB) group (P < 0·0001). No statistically significant differences were observed at other time-points.
