Abstract
Abstract—We studied the dynamics of changes in the content of neuron specific enolase (NSE, EC 4.2.1.11) in the hippocampus, cortex, cerebellum and blood serum of rats at 5th, 10th, and 30th days of postnatal development. It was shown that during the first month of life the content of NSE increases several-fold in all the structures studied, both after hypoxia and in the animals not exposed to hypoxia. It was established that prenatal hypoxia on the 14th day of embryonic development leads to significant changes in the NSE content in all the brain structures studied. In the blood serum, the content of this enzyme is higher in comparison with the control group on the 5th, 10th, and 30th postnatal days in experimental animals. Thus, the lack of oxygen affects the content of this enzyme in both the brain structures and in blood serum of rats, which makes it possible to judge the survival of neurons under conditions of prenatal hypoxia, and also suggests that this index may be used as a marker of fetal CNS disturbance after hypoxia during prenatal development.
