[Changes in the oxidant-antioxidant system activity in patients with hepatic failure treated with hyperbaric oxygenation and actoprotectors]. / Izmenenie aktivnosti oksidantno-antioksidantnoi sistemy pod vliianiem giperbaricheskoi oksigenatsii i aktoprotektorov u bol'nykh s pechenochnoi nedostatochnost'iu.

Effects of hyperbaric oxygenation, bemitil, and solcoseryl used in preoperative treatment of patients with hepatic failure on the oxidant-antioxidant system are studied. Lipid peroxidation (LPO) was assessed from changes in the levels of malonic dialdehyde and diene conjugate and the antioxidant system from the number of SH-groups. Hyperbaric oxygenation led to activation of LPO processes. Bemitil decreased the intensity of LPO by extending the potentialities of the antioxidant system. Antioxidant properties of solcoseryl were not realized through the thiol buffer of the antioxidant system. Only a course of treatment with this drug brings about a stable effect.
