Values are . Statistically significant differences were revealed in relation to measurement I in the US-treated healthy controls (, ). Measurement I: before the treatment; measurement II: 30 min after the treatment; measurement III: 24 hours after the treatment; TBARSpl/er: thiobarbituric acid reactive substances in plasma (10–1 nmol MDA/mL plasma)/erythrocytes (nmol MDA/g Hb); MDA: malondialdehyde; Hb: haemoglobin; SOD: superoxide dismutase (10 U/g Hb); GPx: glutathione peroxidase (U/g Hb); CAT: catalase (IU/g Hb); AcP: acid phosphatase (10–3 nmol 4-NP/mg protein/min); 4-NP: 4-nitrophenol; ASA: arylsulfatase (10–3 nmol 4-NC/mg protein/min); 4-NC: 4-nitrocatechol; CTS D: cathepsin D (10–2 nmol TYR/mg protein/min); TYR: tyrosine; AAT: α1-antitrypsin (10–1 mg TR/mL serum); TR: trypsin.
