THE CHANGES IN THE PERIVENTRICULAR ZONE AND BRAIN CORTEX IN PRETERM NEWBORN WITH VERY LOW BIRTH WEIGHT AND EXTREME LOW BIRTH WEIGHT

The results of autopsy material of preterm newborns very low birth weight (VLBW) and extremely low birth weight (ELBW) brains are presented. In life the brains lesions were detected in the examined newborns with cranial ultrasound and MRI (intraventricular herminal hemorrhages/IVH and hypoxic — ischemic encephalopathy /HIE). In this researching were been using method of microscopy. Postmortem examination confirmed brain cell migration continues after birth in all examined newborns. This study have detailed the directions, positions, thickness cells migration columns. There were found that cells migration thickness and length depend on gestation age of preterm newborn with IVH and HIE. Besides we found the age morphologic differences in cell structures cerebral cortex in preterm newborns.
