Low concentrations of NEI do not affect the recruitment of WBCs into the wound chambers.

WBCs in the chambers were counted at 24 hours and expressed as ratios of inhibitor-treated to solvent-treated chambers. A ratio of 1 indicates an equal number of leukocytes in the solvent and NEI chambers. Low NEI concentrations (0.10 and 0.25 mM), but not higher concentrations (0.5, 1.0, and 2.0 mM), maintained an equal WBC count in a pair-wise comparison between the solvent and NEI chambers (n = 2-7, except for the 2.0 mM data-point, which represents only one experiment). Error bars represent SEM.
