| Summary: | The impact of massive blood loss on cerebral blood flow-function relationships was studied in rats in the postis-chemic period. Anxiety was examined in the raised cross-shaped labyrinth. Cerebral blood flow was registered by a laser Doppler flowmeter. One-hour massive blood flow substantially increased the level of anxiety in 75% of the rats following 7 and 20 days. There were no significant behavior changes in 25% of the animals. Experimental animals with preserved behavioral parameters showed cerebral blood flow resistance to ischemia and reperfusion while rats with increased anxiety were found to have delayed postischemic hypoperfusion. Thus, a relationship was found between the behavior of the rats and the resistance of cerebral blood flow to ischemia and reperfusion. |
