Background: Neuropsychiatric adverse effects of interferon (IFN) alpha are well known. There is little clinically relevant research on animal models of depression with recombinant human IFN alpha 2b (rhIFN-α2b).

Aim: To identify an appropriate dose and duration of administration of recombinant human interferon alpha-2b (rhIFN-α2b) to establish a convenient and clinically relevant murine model of chronic rhIFN-α2b-induced depression using the forced swim test (FST).

Background: Cyclooxygenase-2 (COX-2) mechanisms are involved in glutamate-mediated learning and memory as well as in glutamatergic excitotoxicity. Electroconvulsive therapy (ECT)-induced amnesia may arise from glutamatergic excitotoxicity; if so, COX-2 inhibition may attenuate retrograde amnesia with ECT.

Methods: Wistar rats which received celecoxib (15 mg/kg per day) or vehicle for 18 days were trained for 3 days on a passive avoidance task.

We sought to explore nonselective vs. selective COX mechanisms in ECS-induced retrograde amnesia using indomethacin and celecoxib as in vivo probes. Adult Wistar rats (n=72) which showed adequate learning on a passive avoidance task received 5 once-daily 30 mC true or sham ECS.

Background: Nonsteroidal antiinflammatory drugs (NSAIDs) have been suggested to retard cognitive decrements in patients with Alzheimer's disease. We postulated that NSAIDs also may protect acute disruption of memory.

Methods: We studied the effect of indomethacin (4 mg/kg/day) administered daily for 19 days on retrograde amnesia induced by two once-daily electroconvulsive shocks in rats.
