Abstract:
Objective To investigate the effect of GM 1 on vasospasm after subarachnoid hemorrhage.Methods Twenty-five wistar rats receiving intracisternal injection of 0.15 ml autologous nonheparinized blood or 0.15 ml saline two times were divided into five groups as follows: control group, cerebral vasospasm (CVS) group, Nimodipine group, GM 1 therapy group and GM 1 prevent group. The cortical regional cerebral blood flow (rCBF) was measured by hydrogenate clearance method at 0, 0.5, 1, 3 and 6h respectively. After perfusion and fixation, capillary vessels in temporal lobe cortex were labeled with anti-factor Ⅷ and observed by microvascular graphic analysis. Results (1) Compared with control group, rCBFs in CVS group, Nimodipine group and GM 1 therapy group were apparently decreased after second intracisternal blood injection (all P
