Effects of docosahexaenoic acid (DHA) treatment of neutrophils on pneumolysin-mediated influx of Ca²⁺

System	Amount of cell-associated 45Ca2+ (pmoles/107 cells/5 min)
Neutrophils only	180 ± 10
Neutrophils + 5 µg/ml DHA	224 ± 19
Neutrophils + 8·37 ng/ml pneumolysin	2406 ± 50*
Neutrophils + DHA + pneumolysin	332 ± 23

The results are expressed as the mean values ± s.e.m. of a single representative experiment (3 in the series) with 6 replicates for each system.

^*P < 0·05 for comparison with each of the other systems.
