Endogenous heme oxygenase prevents impairment of cerebral vascular functions caused by seizures.


In newborn pigs, the mechanism of seizure-induced cerebral hyperemia involves carbon monoxide (CO), the vasodilator product of heme catabolism by heme oxygenase (HO). We hypothesized that seizures cause cerebral vascular dysfunction when HO activity is inhibited. With the use of cranial window techniques, we examined cerebral vascular responses to… (More)
