Abstract

BACKGROUND: Spinal cord injury has been reported after perinatal asphyxia in full-term neonates.

OBJECTIVES: To examine the role of excessive nitric oxide production in perinatal spinal cord injury.

SUBJECTS AND METHODS: Tissue samples of 18 full-term neonates who died of hypoxic-ischemic encephalopathy were analyzed for the presence of nitrotyrosine (NT).

RESULTS: NT was demonstrated in 5 of these 18 neonates. In addition, activated caspase 3, a marker of apoptosis, and CD68, as a marker of inflammation, could be demonstrated in some infants.

CONCLUSIONS: excessive nitric oxide production and subsequent NT formation is seen in spinal cord tissue after severe perinatal asphyxia. This finding may be relevant for the development of neuroprotective strategies.
