N2 - Insulin-like growth factor-1 (IGF-1) was applied topically on the brain surface of reperfused rat brain after 60 min of transient middle cerebral artery (MCA) occlusion. In contrast to the cases treated with vehicle, the infarct volume was greatly reduced at 24 h of reperfusion by the treatment with IGF-1. Immunohistochemical analysis in the MCA territory showed that the increase of cyclin-dependent kinase 5 (cdk5) was greatly reduced, and that the decrease of the critical regulatory subunit of cdk5, p35, was preserved with treatment of IGF-1. The present results suggest that IGF-1 has a significant effect on ameliorating brain injury after transient focal brain ischemia with affecting the expressions of cdk5 and its activator p35.
