  • Abstract
  • Look Inside

Neuronal damage induced by ischemia involves various changes in neurotransmissin. Nitric oxide (NO), a putative neurotransmitter and/or neuro-modulator has some role in this neuronal damage.

In the present study, the effect of NO on the terminal site of dopamine (DA) neurons in the rat striatum was examined using the microdialysis tech-nique. First perfusion with sodium nitroprusside (SNP) as an NO donor increased extracellular DA (10 mM, 460%; 1 mM, 140%) in the striatum and decreased its metabolites.
