it is proposed that (a) the induction of hsp72 in hippocampal sectors correlates with their vulnerability to global ischemia (ca1 greater than hilus greater than ca3 greater than dentate gyrus); (b) the induction of hsp72 in hippocampal cells correlates with their vulnerability to global ischemia in that mild ischemia induced hsp72 only in neurons, moderate ischemia in neurons and glia, and severe ischemia only in capillary endothelial cells; (c) the failure to induce hsp72 in hippocampal neurons in 2 cases of 10 min ischemia may be related to severe injury causing disruption of protein synthesis in these cells. |
