Figure 1.

Patients have lower monocytic TM expression in combination with higher monocytic apoptosis and plasma eotaxin-2 level after surgery. A. Blood samples were collected at preincision and 24 hours after the commencement of CPB. Membrane TM expression and annexin V expression on monocytes were analyzed with flow cytometry. B. According to the tendency toward TM expression and the apoptosis situation, we distributed the patients with more than a 2-fold increase in annexin V into group 1 (11 patients) and the others into group 2 (7 patients). The bar graph shows the expression ratio (% before surgery) of TM and annexin V in group 1 (■) and group 2 (□). C. Changes in plasma concentrations of eotaxin-2 in patients who had undergone CABG. Data are presented as the means ± SEM; *P<0.05 was considered significant.
