This study aims to explore the effect of fluoxetine on memory, locomotor and depressive behavior in transient forebrain ischemic model of gerbil.
Doses of fluoxetine (10, 40 mg/kg) or vehicle were intraperitoneally administered once 30 min before ischemic surgery in gerbil. Novel object recognition test, spontaneous motor activity, learned helplessness test were performed 4 days, 8 days, or 9 days, respectively, after sham or ischemic surgery.
Fluoxetine treatment (40 mg/kg) significantly reduced recognition memory in sham operated gerbil. However, fluoxetine (10, 40 mg/kg) did not affect ischemia-induced impairment in recognition memory. The treatment of fluoxetine (10, 40 mg/kg) significantly inhibited locomotor hyperactivity induced by transient ischemia even though fluoxetine (40 mg/kg) did not affect spontaneous motor activity in the sham operated gerbils. Fluoxetine did not affect depressive behavior in sham and ischemic gerbils.
The treatment of fluoxetine inhibited ischemia-induced hyperactivity, but did not affect memory and depressive behavior in transient forebrain ischemic gerbils.
