Reparative changes in the sensorimotor cortex of the offspring in moderate prenatal alcoholism]

Sensorimotor cortex of 21-, 30-, 60-day-old offspring given prenatally moderate alcohol (2 g/kg) manifested signs of compensatory type: double nerve and glial cells, open capillaries, nearby nerve and glial cell bodies with basal membrane of capillaries. Intracellular reparative processes in dystrophic neurons were observed: nuclear activation, hyperplasia of cytoplasmic organelles, hypertrophy of some of them. Reparative processes are more distinct in 30-day-old rat offspring In 60-day-old offspring a polymorphic pattern of cortical synapses ultrastructure was found. However, dystrophic changes of neurons and interneuronal connections still remain.
