Abstract
The objective was to explain the discrepancy in the development of hypoxic ischemic brain injury (HIE) in some asphyxiated newborns rather than others. Forty newborns were classified according to their cerebrospinal neuron-specific-enolase (CSF-NSE) levels on their 5th-day of life; group 1 with low-NSE ( n = 25). The remaining 15 newborns had high-NSE and were further divided into a group with no HIE ( n = 10, group 2) and another with HIE ( n = 5, group 3). CSF-NSE, totalhydroperoxide (TH), biological-antioxidant-potentials (BAPs), 12 cytokines and Erythropoietin (EPO) were measured. The TH/BAP gave the oxidative-stress-index (OSI). The BAPs of serial dilutions of three types of EPO were tested. CSF-NSE and TH and mean OSIs were higher in group 3. IL-8 and mean BAPs were higher in group 2 than in group 1. EPO was less detected in group 3. Serial EPO dilutions correlated with their BAPs. Compensatory antioxidants and IL-8 elevation could be protective of perinatal asphyxic brain injury. Antioxidative effect of EPO could be neuroprotective. [ABSTRACT FROM AUTHOR]
