Abstract:Objective: To investigate the neuroprotective effects of bFGF (basic fibroblast growth factor) via intranasal administration for ischemic neurons of brain. Methods: The transient focal cerebral ischemia-reperfusion model of adult male SD rats was established with a method of line-plugging to the external carotid artery. Twenty-four hours after the reperfusion, behavioral test (neurologic deficit scoring) was carried out to evaluate the neurological deficiency. The neuroprotective effects of bFGF via intranasal administration to the model rats were evaluated with neurologic deficit score, infarct volume, histology and immunohistochemistry staining. Results: The transient focal cerebral ischemia-reperfusion model were established successfully. Comparing with the ischemia-reperfusion group, the level of infarction volume was significantly decreased (P<0.05), the number of nerve cells were increased and the expression of p-Akt positive cells were significantly up-regulated via intranasal administration of bFGF group. Conclusion: By the new pathway of nasal administration, bFGF can decrease the infarction volume and protect neurons from cerebral ischemic injury.
