Using [14C]iodoantipyrine, regional brainstem blood flow was measured in the rat 2 h after occlusion of the left anterior inferior cerebellar artery (AICA) and 30 min after occlusion of the left vertebral artery (VA). Two hours after occluding the left AICA, the mean +/- SEM value of blood flow in 6 animals in the right superior olive was 2.13 +/- 0.13 ml/g/min and in the left side, 1.13 +/- 0.11. Thirty minutes after occlusion of the left VA, there were no significant differences between the right and left sides. Blood flow changes were assessed in the hindbrain structures between the control group, 30 min after occlusion of the left VA and 2 h after occlusion of the left AICA. Changes observed in the blood flow in the hindbrain structures suggest that the extra volume of the blood flow might be concealed in the brainstem. However, whether the recovery of the blood flow rate indicates the recovery of the brainstem function remains unclear.
使用[14C]碘安替比林，在大鼠左侧小脑下前动脉（AICA）闭塞后2小时和左侧椎动脉（VA）闭塞后30分钟测量其脑干局部血流。左侧AICA闭塞2小时后，6只动物右侧上橄榄核的平均血流值±标准误为2.13±0.13毫升/克/分钟，左侧为1.13±0.11。左侧VA闭塞30分钟后，左右两侧无显著差异。评估了对照组、左侧VA闭塞30分钟后和左侧AICA闭塞2小时后脑干结构中的血流变化。在后脑结构中观察到的血流变化表明，额外的血流量可能隐藏在脑干中。然而，血流速度的恢复是否表明脑干功能的恢复仍不清楚。
