Abstract
Three considerations, taken together, make research on the treatment of brain ischemia seem eminently worthwhile: (a) during ischemia, tissue destined for infarction is usually receiving an appreciable fraction of the minimum blood flow required for cell survival [7, 10, 13]; (b) the time to irreversibility is considerably longer than previously thought and may be measured in terms of half hours or hours [6, 8]; (c) restoration of circulation usually can be anticipated within hours or days as a result of clot lysis or collateral enlargement. Aggressive measures to forestall cell death may therefore be justified.
