Abstract:
Using fluorescent differential display and quantitative reverse-PCR, we found in the rat vasospasm model that heme oxygenase-1 messenger RNA was induced in basilar artery. Intracistemal injection of antisense OH-1 oligodeoxynucleotide significantly reduced HO-1 mRNA and HO-1 protein levels and enhanced angiographic vasospasm. Thus, we demonstrate that HO-1 induction may play a important role in the resolution of delayed vasospasm after subarachnoid hemorrhage.
