| Outline of Final Research Achievements |
Several clinical studies have indicated that serotonin re-uptake inhibitor administration after acute ischemic stroke can improve clinical recovery. Fluoxetine (FLX: one of the serotonin re-uptake inhibitor) has several mechanisms which contribute to relieve the ischemic brain damage. The goal of this study is to evaluate the neuroprotective effect of FLX for a long observation period after cardiac arrest and cardiopulmonary resuscitation in mice. Fourteen days after ischemia, FLX did not have an influence on the number of survival neurons in hippocampus. However, FLX administration increased the number of immature neurons. At this time point, memory function improved in FLX group.
Fluoxetine improved memory function after cardiac arrest. This recovery may be due to neurogenesis in hippocampus, but not due to surviving neurons. Further investigation is needed to clarify the interaction of memory function and neurogenesis after fluoxetine administration.
