Fig. 1. Ratio of adhesion molecule expression on leukocytes from salvaged wound blood (SWB) related to venous blood (VB). Expression of L-selectin (CD62L; A ), CD18 (B ), and CD11b (C ) determined from flow cytometric analysis of 10,000 events/sample as overall expression on all leukocytes (Leukocytes) and as expression on neutrophil (PMN) or monocyte (MO) subpopulations. Leukocyte subpopulations were identified by light scatter properties and expression of CD14. Ratios (SWB/VB) are presented as medians, 25–75%, and 90% confidence intervals and outliers of 25 independent experiments (* P < 0.05; Wilcoxon signed rank test, Bonferroni–Holm correction).
