Leukocytes play a role in elevation of in-circuit pressure. (A) Whole blood or PRP stored for 7 days was administered to the circuit and then 5 U/mL of unfractionated heparin was administered at 15 minutes. In-circuit pressure was monitored for 60 minutes. N = 6 per group. (B) The paired t-test was used to analyze the difference in the area under the curve (AUC) between whole blood and PRP. N = 6 per group. *p < 0.05. (C) Relative numbers of erythrocytes (RBC), leukocytes (WBC), and platelets (PLT) to the initial numbers in whole blood are shown. N = 3 per group. (D) The filter was removed at 60 minutes and analyzed by immunofluorescence. Fibrin(ogen) was labeled in red and DNA was labeled in blue. Representative images of the whole filter (scale bars: 10 mm) and the magnified view (scale bars: 50 μm) are shown.
