Table 1.

The concentration of thiobarbituric acid reactive substances (TBARS) in erythrocytes and blood plasma, and the activities of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) were determined in patients with difficult-to-heal skin wounds receiving hyperbaric oxygen (HBO) treatment.

Determined parameter HBO	Before procedure	After 1st HBO procedure	After 25th HBO procedure
TBARS er. (nmol MDA/g Hb)	25.36 ± 7.94	23.87 ± 7.57	25.11 ± 7.89
TBARS pl. (nmol MDA/mL)	0.57 ± 0.15	0.55 ± 0.15	0.51 ± 0.14
CAT (104IU/g Hb)	64.06 ± 10.47	62.14 ± 11.90	65.51 ± 6.59
SOD (U/g Hb)	626.49 ± 85.04	732.31 ± 88.74	732.31 ± 82.57
GPx (U/g Hb)	8.58 ± 4.10	7.40 ± 4.63	7.08 ± 4.00

TBARS er.: thiobarbituric acid reactive substances in erythrocytes; TBARS pl.: thiobarbituric acid reactive substances in plasma; CAT: catalase; SOD: superoxide dismutase, GPx: glutathione peroxidase. Results are expressed as Mean ± SD. No statistically significant differences.
