Total peritoneal leukocytes 0 to 96 hours after peritoneal stimulation with thioglycollate. (-▪-)Plg(+/+), (-•-) Plg(+/−), and (-▴-)Plg(−/−). Unstimulated peritoneum is represented as t = 0. Values represent mean ± SEM. For Plg(+/+),Plg(+/−), and Plg(−/−) mice P = .003 at 72 hours poststimulation determined by one-way ANOVA
