Functional and biochemical criteria for investigation of brain development disorders

Abstract

Functional state and creatine kinase (CK) activity in the amniotic fluid and blood of anencephalic fetuses was studied in the second trimester of pregnancy with the following pathomorphological investigation of the state of their CNS to reveal possible markers of development disorders. The extent of neurological disorders in newborn infants was retrospectively compared with data from functional studies of components of a biophysical profile (motor-cardiac reflex, heart rhythm oscillations, respiratory movements) and with CK activity in the amniotic fluid and blood of fetuses with hemolytic disease and fetuses of diabetic mothers and normal mothers in the third trimester of pregnancy. The results revealed informative indices of fetal CNS developmental disorders in the prenatal period that are of importance for predicting a prognosis of the extent of neurological disorders in newborn infants. These results will allow the establishment of criteria for evaluation of fetuses to reveal possible disorders in the formation of the CNS.
