Abstract

The authors examined the role of nitric oxide (NO) in the relationship between kainate-induced neuronal death and locomotion changes. Locomotion was significantly increased 1 h after kainate injection, suggesting that kainate induced NO and dopamine release. Cell death occurred in the CA1 (41%) and CA3 (54%) regions at 12 h. At 7 days, GABAergic neurons in striatum were lost, suggesting possible pyramidal neuron synapse with striatal GABAergic neurons, and pyramidal neuron damage leading to deafferentation and degeneration of striatal GABAergic neurons. Pre-administration of Nw-nitro-L- arginine-methyl-ester or 7-nitroindazole reduced these effects. These results indicate that NO may modulate kainate-induced neuronal death and locomotion.
