[Effects of intravasal laser irradiation of blood on lipid peroxidation in patients with abdominal surgery].

Lipid peroxidation and the antioxidant system were studied in 36 patients with surgical diseases of the gastrointestinal tract. Time course of these parameters was studied in the postoperative period. Differences in lipid peroxidation during standard endovascular laser therapy were revealed, caused by the initial status of the antioxidant system. Combined use of endovascular laser irradiation of the blood and antioxidant therapy helped rule out the undesirable induction of free-radical processes in these patients.
