Cell differentials of peritoneal leukocytes 0 to 96 hours after peritoneal stimulation with thioglycollate as determined by Wright stain. (A) Peritoneal neutrophils; (B) peritoneal macrophages; (-▪-) Plg(+/+), (-•-) Plg(+/−), and (-▴-) Plg(−/−). Unstimulated peritoneum is represented as t = 0. Values represent mean ± SEM. Using one-way ANOVA, P = NS for neutrophils at 6 hours poststimulation andP < .001 for macrophages at 72 hours poststimulation forPlg(+/+), Plg(+/−), and Plg(−/−) mice.
