  • Title: The sodium-potassium ATPase inhibitor ouabain is neurotoxic in the rat substantia nigra and striatum.
    Author: Lees GJ, Leong W.
    Journal: Neurosci Lett; 1995 Mar 24; 188(2):113-6. PubMed ID: 7540738.
    Abstract:
    Injection of ouabain, a potent and selective inhibitor of Na+/K+ ATPase, into the rat striatum and substantia nigra caused a selective neuronal loss in up to 70% of the lesioned area. However, there was a glial cell/macrophage proliferation in the core of the lesion. Neuronal loss was demonstrated by staining in vivo with Trypan Blue, a marker for dead cells. Cholinesterase staining was also lost, but in the striatum this was revealed only after pre-existing enzyme was irreversibly inhibited in vivo.
