Table 1

Statistical comparison of oxidative and antioxidant parameters in the on-pump group in the preoperative, peroperative, and postoperative periods.

Parameters	Preoperative period	Peroperative period	Postoperative period
MDA (nmol/ml)	2.61 ± 0.15^a	3.48 ± 0.21^b	2.28 ± 0.13^a
GSH (μmol/g Hb)	1.44 ± 0.17^a	1.57 ± 0.19^ab	1.93 ± 0.20^b
CAT (k/g Hb)	23.22 ± 2.72^ab	30.11 ± 2.90^a	23.58 ± 3.38^b
SOD (U/g Hb)	31.57 ± 1.61^a	34.33 ± 1.71^a	41.04 ± 2.11^b

Letters a and b show statistically different groups.
