Biochemical parameters of prooxidant status in patients before surgery.

Indicators/Groups TBA-reactive products P Diene conjugates P 8-isoprostane P value
Control (n = 20) 3.58 ± 0.44 P1 = 0.000 1.74 ± 0.22 P1 = 0.000 2.08 ± 0.48 P1 = 0.000
With necrosis of the small intestine (n = 27) 7.12 ± 0.87 P2 = 0.000 3.95 ± 0.52 P2 = 0.000 4.95 ± 0.67 P2 = 0.000
Without necrosis of the small intestine (n = 44) 6.78 ± 0.71 P3 = 0.078 3.46 ± 0.61 P3 = 0.005 4.51 ± 0.78 P3 = 0.004
Survivors (n = 59) 6.37 ± 0.71 P4 = 0.001 3.53 ± 0.43 P4 = 0.000 4.42 ± 0.52 P4 = 0.013
Non-survivors (n = 12) 7.39 ± 0.99 4.2 ± 0.26 4.88 ± 0.77

TBA = thiobarbituric acid; DC = diene conjugates; Note: P1 – reliable between control and strangulation; P2 – reliable between control and obturation; P3 – reliable between strangulation and obturation; P4 – reliable between survivors and non-survivors.
