[Free radical modification of proteins in brain structure of Sprague-Dawley rats and some behaviour indicators after prenatal stress].

We studied the influence of late prenatal stress on free radical oxidation processes in Sprague-Dawley rats cortex, striatum, hippocampus, hypothalamus proteins. It was shown that after prenatal stress most changes were observed in hypothalamus and hippocampus. It was shown that in hypothalamus spontaneous oxidation level increased, but level of induced oxidation decreased, the opposite changes were found in hippocampus.

[Free radical oxidation of lipids in the rat hypothalamus under stress after cortisol pretreatment].

Free radical oxidation of lipids in the rat hypothalamus after cortisol pretreatment weas investigated. Three-fold cortisol injection (25 mg/kg, once per day) resulted in significant decrease of average level of Schiffbases, the final products of lipid oxidation. Stress causes increase of average level of Schiff bases in the control animals (without cortisol pretreatment).

[Influence of prenatal stress on free radical oxidation lipids, both proteins and activity of superoxiddismutase in neurones and glial cells of the rat brain cortex].

Processes of free radical oxidation of protein, lipids, and activity of superoxiddismutase in neurons and glial cells of the rat brain cortex in ontogenesis and after prenatal stress. Irrespective of age, the level of free radical oxidation of lipids and proteins in neurons is higher in comparison with the glia. The same was found in the study of superoxiddismutase activity.
