Abstract:
Objective To study the effect of intra arterial thrombolysis in combination with basic fibroblast growth factor (bFGF), and the protecting mechanism of the bFGF. Methods 50 male Wistar rats were subjected to middle cerebral artery occlusion (MACO) for 4 hours by a single fibrin rich clot. The rats were randomly assigned to the following two expremental groups: 1) treatment with urokinase alone; 2) treatment with urokinase and bFGF. The neurological deficits and the volume of lesions on MRI T2WI were observed at different periods after therapy. The expression of bax were analyzed by immunuohistochemical method at each time point. Results Bax expression increased at 3 hours after reperfusion, and reached the peak level at 12h reperfusion. At 6h after therapy, expression of bax ( P
