This study used a postnatal day 5 rat model of GMH to explore immune response, brain injury, and neurobehavioral changes after hemorrhagic injury. The results showed that CD45\n                    <jats:sup>high<\/jats:sup>\n                    \/CD11b\n                    <jats:sup>+<\/jats:sup>\n                    immune cells increased in the brain after GMH and were accompanied by increased macrophage-related chemokine\/cytokines and inflammatory mediators. Hematoma formed as early as 2\u2009h after injection of collagenase VII and white matter injury appeared not only in the external capsule and hippocampus, but also in the thalamus. In addition, GMH caused abnormal motor function as revealed by gait analysis, and locomotor hyperactivity in the elevated plus maze, though no other obvious anxiety or recognition\/memory function changes were noted when examined by the open field test and novel object recognition test. The animal model used here partially reproduces the GMH-induced brain injury and motor dysfunction seen in human neonates and therefore can be used as a valid tool in experimental studies for the development of effective therapeutic strategies for GMH-induced brain injury.\n
