This finding suggests that infarction at its acute stage gives rise to an increased release of <jats:italic>\u03b2<\/jats:italic>-endorphin. Such a mechanism is consistent with the possibility that the reported therapeutic effect of naloxone in cerebral ischemic lesions may result in part from the antagonism of the centrally released
