RESUMO
Objective To investigate the expressions of Slit2 and Nogo-A in the ipsilateral hippocampus after cerebral hemorrhage in rats.Methods A total of 64 adult Sprague-Dawley (SD) rats was randomly divided into control and model groups.Collagenase Ⅶ was used to induce cerebral hemorrhage model.Immunohistochemistry was used to detect the expressions of Slit2 and Nogo-A in hippocampus at the cerebral hemorrhage side at the time points (24 h,7 d,14 d,and 21 d).Results Compared to the control group,the expressions of Slit2 and Nogo-A were significantly enhanced in model group (P ＜0.01),with the highest level at the 7 d.Conclutions Cerebral hemorrhage can significantly enhance expressions of Slit2 and Nogo-A with a positive correlation of Slit2 and Nogo-A,which might have an important effect on the recovery of brain injury.
