Intracerebral hemorrhage (ICH) is a devastating form of stroke. Misoprostol, a synthetic prostaglandin E1 (PGE1) analog and PGE2 receptor agonist, has shown protection against cerebral ischemia. In this study, we tested the efficacy of misoprostol in the 12-month-old mice subjected to 1 of 2 complementary ICH models, the collagenase model (primary study)(More)
Inflammatory responses mediated by prostaglandins such as PGE2 may contribute to secondary brain injury after intracerebral hemorrhage (ICH). However, the cell-specific signaling by PGE2 receptor EP2 differs depending on whether the neuropathic insult is acute or chronic. Using genetic and pharmacologic approaches, we investigated the role of EP2 receptor(More)
In this study, we examined the effect of progesterone on histopathologic and functional outcomes of intracerebral hemorrhage (ICH) in 10- to 12-month-old mice. Progesterone or vehicle was administered by intraperitoneal injection 1 hour after collagenase-induced ICH and then by subcutaneous injections at 6, 24, and 48 hours. Oxidative and nitrosative stress(More)
