Energy metabolism was impaired in submerged rat hippocampal slices using the inhibitors amytal, 3-nitropropionate (3-np), sodium cyanide (1 mM each) and the uncoupling agent 2,4-DNP (200 microM).

We found that SK2 or Kv1.1 protected not only against kainate or glutamate excitotoxicity but also increased survival after sodium cyanide or staurosporine.
In vivo overexpression of either channel in dentate gyrus reduced kainate-induced CA3 lesions.

Incubation with 3 mM SNP for up to 2 h produced neuronal damage characterized by "nuclear ballooning" in CA3 and CA1 pyramidal neurons and interneurons.

Previous studies in this laboratory demonstrated that overexpression of the gene for the calcium-binding protein calbindin D28K, via herpes simplex virus (HSV) amplicon vector, increases the survival of hippocampal neurons in vitro following energetic or excitotoxic insults but not following application of sodium cyanide.
We now report that in vivo hippocampal infection with the calbindin D28K HSV vector increases neuronal survival in the dentate gyrus after application of the antimetabolite 3-acetylpyridine and increases transsynaptic neuronal survival in area CA3 following kainic acid neurotoxicity.

Histological analysis using thionin staining and MAP2 immunostaining showed differences in the temporal profile of neuronal damage in hippocampal and neocortical structures, i.e., in decreasing order, CA1 (7 min) > CA3 and neocortical layers II, III, V, VI (30 min) > DG and neocortical layer IV (60 min).
