[Free-radical and neuroimmune processes in primary and repeated craniocerebral trauma (in an experiment)].
The impact of primary and repeated brain injury (BI) (moderate contusion of the brain) on changes of pro- and antioxidative processes in the brain and blood, as well as on the body's neuroimmune responses during 30 days following injury were studied in an experiment on albino rats. The changes in the rate of lipid peroxidation (LPO) were shown to be significantly higher in repeated BI than in primary one. There was no correlation between the changes in the rate of LPO in the blood and in the brain tissue. Immune disorders, namely: the proliferative activity of T and B lymphocytes were slightly milder than in primary BI while in repeated BI, neurosensitization was detectable earlier, which was more pronounced. Thus, goal-oriented correction of free radical processes should be made in the brain and of neuroimmune disorders in BI.
