Blood was drawn from the abdominal aorta at the end of arteriovenous shunt test period and anticoagulated with indomethacin-EDTA-Na₂. Plasma samples were prepared by centrifugation and analyzed by radioimmunoassay. Data are expressed as mean±SEM (each group, n = 10). ^# P<0.05, ^## P<0.01 compared with normal group, *P<0.05, **P<0.01, ***P<0.001 compared with thrombotic control group.
