title: Brain damage caused by ischemia: pathophysiological and pharmacological aspects.
abstract: The distribution of brain cell injury after ischemic challenge is remarkable because only discrete brain areas are damaged, whereas other structures exhibit a very high resistance (selective neuronal death). The calcium hypothesis, one of the hypotheses that has been formulated to explain this selective vulnerability, postulates that an increase in excitatory amino acid release and the large calcium influx during ischemia leads to insufficient energy production and to stimulation of lipases, proteases, and endonucleases. This paper reviews the experimental data concerning the relationship between cerebral blood flow, glucose consumption and hippocampal morphological damage. The neuroprotective effects of some drugs against ischemic damage have also been discussed.
