Zusammenfassung:Citicoline sodium (cytidine-5'-diphosphocholine) has been shown previously to reduce ischemic injury in focal central nervous system models. Intracerebral hemorrhage (ICH) appears to be associated with an area of edema and ischemic injury surrounding the hematoma that may be reduced by neuroprotective therapy. The present study was designed to test whether treatment with citicoline reduces ischemic injury and improves functional neurological outcome in an experimental model of ICH. In 68 Swiss albino mice (26 to 36 g), ICH was induced by collagenase injection into the caudate nucleus. Animals were randomized to receive either: citicoline 500 mg/kg or saline IP prior to collagenase and at 24 and 48 hours. Animals were rated on a 28-point neurological scale and sacrificed at 54 hours. The brains were sectioned, and the volume of hematoma, total lesion, and surrounding ischemic injury was determined. In terms of functional outcome, animals treated with citicoline had improved neurological outcome scores compared with placebo-treated animals: 10.4+/-2.0 versus 12.1+/-2.4 (P
