[Electron microscopic and cytointerferometric study of the cortical neurons from the 2d-generation progeny of preneurosensitized female rats].
A study was made of the sensorimotor cortex of the brain of the second generation offspring of preneurosensitized female rats. Vacuolization of the neurocyte nuclei, elevated lability of nuclear membranes, appearance of numerous dark neurons were discovered at all times of postnatal ontogenesis (from 2 to 90 days). At the same time ultrastructure of a considerable number of neurons was unchanged. The tendency toward normalization of cellular structures was noted by the 3d month. The one-month-old rats demonstrated a decrease in the content of protein substances in the nucleus and cytoplasm of the neurons as compared to normal. By the 3d month this indicator rose but did not reach the control level. It is concluded that neurosensitization of females before pregnancy affects the morphofunctional state of the neurons of the cerebral cortex in both first and second generation offspring, although the changes seen in the latter offspring are less marked, being compensated for with time.
