[The function of the oxidant-antioxidant system in patients with laryngeal cancer].

Lipid peroxidation and antioxidant system were studied at hospital admission, on postoperative day 1, 3 weeks and half a year after surgery in 86 patients with different stages of laryngeal cancer. A correlation is stated between lipid peroxidation disturbances and the defects in the protective antioxidant system. Low-frequency laser irradiation of autoblood produced a clinically beneficial effect and stabilized biochemically the relations between lipid peroxidation and antioxidant systems.
