The Novel 5-Lipoxygenase Inhibitor ABT-761 Attenuates Cerebral Vasospasm in a Rabbit Model of Subarachnoid Hemorrhage

Marcos Barbosa, Adam Stephen Arthur, R. Hunter Louis, Timothy L. Macdonald et autres

OBJECTIVE: Eicosanoids have been implicated in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage (SAH). Leukotrienes, 5-hydroxyperoxyeicosatetraenoic acid, and 5-hydroxyeicosatetraenoic acid are part of this group of substances, resulting from the 5-lipoxygenase activity on arachidonic acid metabolism. This study examined the effects …
