Protection of rat hippocampus against ischemic neuronal damage by pretreatment with sublethal ischemia.

Abstract

We examined whether preconditioning with sublethal ischemia protects against neuronal damage following subsequent lethal ischemic insults. Forebrain ischemia for 3 min in Wistar rats increased heat shock protein-70 immunoreactivity in the hippocampal CA1 subfield but produced no neuronal damage. Preconditioning with 3 min of ischemia followed by 3 days of reperfusion protected against hippocampal CA1 neuronal damage following 6 and 8 min of ischemia but not damage after 10 min of ischemia. The result strongly suggests that stress response induced by sublethal ischemia protects against ischemic brain damage.
