FIG. 1.

Percent hyphal damage induced by PMNs from saline-treated mice (Untr PMN) or from mice treated with GM-CSF (GM-PMN) alone, POS alone, or the combination at an effector cell-to-target cell ratio of 5:1. Bars indicate means ± standard errors of the mean of eight experiments. The asterisks indicate statistical differences (P < 0.01) found by ANOVA with the Tukey posttest for multiple comparisons between the combination of PMNs from saline-treated mice and mice treated with POS and PMNs from either saline-treated mice or mice treated with POS alone and between the combination of PMNs from mice treated with GM-PMN and POS and PMNs from mice treated with either GM-PMN or POS alone.
