A neuromorphological analysis of the motor area of the cerebral cortex in rat pups subjected to prenatal exposure to normal and pathological blood serum]

Morphological quantitative and qualitative analysis of the pyramidal neurones in the motor cortex of rat puppies after administration of the blood serum from human donors with central motor disorders reveals the dependence of the quality and quantity of neurones from the effect of corresponding blood sera. Pathologic blood serum decreases the number and induces degradation of dendritic organization of the pyramidal neurones. The effect of the blood sera on quantitative and qualitative properties of the pyramidal neurones in rat puppies depends on the age of donor infants with central motor disorders. Blood serum from newborn babies with motor dysfunctions significantly decreases the number of labeled pyramidal neurones and results in degradation of dendritic organization, whereas sera from 11-13-year infants only insignificantly affect these characteristics.
