We examined whether mild brain hypothermia during pretreatment with sublethal 2-min ischemia affected the tolerance to subsequent lethal 5-min ischemia. The neuronal densities in the hippocampal CA1 sector of gerbils preconditioned at mild brain hypothermia (32% of normal) were significantly lower than those in gerbils preconditioned at brain normothermia (70% of normal). 72-kDa heat-shock protein immunoreactivity in the CA1 sector preconditioned at mild hypothermia was reduced. These results suggest that mild brain hypothermia during pretreatment with sublethal ischemia reduces the tolerance to subsequent lethal ischemia.

D007036 Hypothermia, Induced Abnormally low BODY TEMPERATURE that is intentionally induced in warm-blooded animals by artificial means. In humans, mild or moderate hypothermia has been used to reduce tissue damages, particularly after cardiac or spinal cord injuries and during subsequent surgeries.

D006624 Hippocampus A curved elevation of GRAY MATTER extending the entire length of the floor of the TEMPORAL HORN of the LATERAL VENTRICLE (see also TEMPORAL LOBE). The hippocampus proper, subiculum, and DENTATE GYRUS constitute the hippocampal formation. Sometimes authors include the ENTORHINAL CORTEX in the hippocampal formation.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
