[Various characteristics of morphological changes in the brain in newborn infants with intrauterine and perinatal damage of the central nervous system].

Pathomorphological examination of the brain was carried out in 8 infants with severe forms of perinatal encephalopathy who died on the 17-th-25th day of life from intercurrent diseases. The investigation revealed a combination of circulatory disorders, dystrophic changes in neurons, fibers, and glia as well as focal productive inflammation of the medulla (predominantly in the area of lateral ventricle walls). An original technique was developed for the determination of the volumetric density of Betz's cells. It was elucidated that the number of Betz's cells in newborns with severe forms of perinatal encephalopathy was considerably lower as compared to age-matched infants without any signs of central nervous system impairment.
