Abstract
Intracerebral hemorrhage (ICH) is a devastating subtype of stroke that is associated with high morbidity and mortality. However, up to now, there are no effective prevention methods or specific therapies to improve its clinical outcomes. Herein, we explore preliminarily the efficacy of crocin, a carotenoid extracted from the stigma of saffron known for its anti-oxidation and free radical scavenging activities, in a mouse ICH model induced with collagenase infusion. Crocin or saline was administrated 6 hours after ICH and then every 12 hours for up to 7 days. Neurological scores were examined on days 1, 3, and 7 after ICH. Mice were sacrificed after1, 3, and 7 days of crocin treatment for examination of histology and immunohistochemistry. The results showed that oral administration of crocin attenuated the neurological deficits and reduced the myelin loss, neuron degeneration, iron deposition, reactive oxygen species (ROS) production and heme oxygenase-1 (HO-1) expression in the early stage of ICH, making it potential to be an ideal candidate for medical therapy of ICH in clinic.
