Fig. 4From: Sera from severe trauma patients with pneumonia and without infectious complications have differential effects on neutrophil biologyOxidative burst activity of neutrophils after their incubation with serum samples from major trauma patients (TP). Serum samples were obtained from TP (n = 18, all). TP were grouped to no inf. without pneumonia (n = 9) or inf. group with pneumonia (n = 9). Samples were obtained at admission to emergency department (ED), a day prior pneumonia diagnosis (1 d prior inf) or at the day of diagnosis (1 d prior inf). Samples from the equal post-injury days in the corresponding no inf. group were used. Neutrophils were isolated from healthy volunteers (HV, n = 9). Oxidative burst activity of neutrophils after their incubation with TP’s serum (20% in culture medium) or control without serum addition (ctrl) for two hours was determined by flow cytometry. Data are represented as mean ± SEM. p < 0.05 *: vs. ctrl, #: no inf. vs. corresponding inf. groupBack to article page
