Fig. 2. (  A ) Representative pattern of thrombin in the plasma of a patient operated on for abdominal aortic aneurysm repair before (bas. = baseline) and at 6, 12, 24, and 36 h after surgery. Images were obtained from the two-dimensional electrophoresis gels using a pH range of 3 to 10. (  B ) Representative Western blots for thrombin performed in plasma samples obtained before (bas. = baseline) and 6, 12, 24 and 36 h after abdominal aortic aneurysm surgery (AAA) or abdominal surgery (AS). (  C ) Densitometric assay of Western blots performed in plasma from AAA (  filled circles ) and AS patients (  empty circles ).
