title: [Prognostic value of the parameters of free radical oxidation in traumatic brain injury].
abstract: The dynamics of lipoperoxides content and activity of antioxidant (glutathione peroxidase, superoxide dismutase, catalase) and prooxidant (xanthine oxidase) enzymes were investigated in the blood and cerebrospinal fluid of patients with traumatic brain injury of various severity depending on the left- or right-hemisphere localization of injuries. Reciprocal relationship between lipid peroxidation and oxidative modification of proteins from first to 14th day, increase of the level of total antioxidant activity, accompanied with the growth of GP and catalase activity, against the background of decrease in SOD activity from 1 to 7 day have been revealed. Were set lower "average" content of lipid peroxides in the blood and cerebrospinal fluid of patients with the subsequent development of lethal results in compare with cases of favorable outcomes, decrease of geptanofilic lipid peroxides in serum below the reference level, as well as the reduction of antioxidant activity in the blood and cerebrospinal fluid, associated with a sharp falling in superoxide dismutase activity and a significant increase of xanthine oxidase activity, which preceded the lethal results.
