Exposure of cultures to a glucose-free conditioning solution containing sodium azide and 2-deoxyglucose caused neuronal cell death as assessed by cellular uptake of propidium iodide, which was prevented by MK-801, an N-methyl-D-aspartate (NMDA) receptor antagonist.

The N-methyl-D-aspartate (NMDA) receptor antagonist MK-801 blocked sodium azide-induced cell death suggesting that the NMDA receptor contributes to the mediated cell death.

The induction of chemical ischemia by sodium azide and 2-deoxy-D-glucose led to delayed neuronal death in a time- and concentration-dependent manner, as determined by trypan blue exclusion.

Results show that cerebellar granule neurons are not vulnerable to transient glutamate uptake inhibition by L-trans-pyrrolidine-2,4-dicarboxylate (PDC) despite the increase in the extracellular concentration of glutamate, unless they are simultaneously exposed to the mitochondrial toxins 3-nitropropionic acid (3-NP) or sodium azide.
Results show that neuronal damage can be efficiently prevented in the presence of pyruvate and the N-methyl-D-aspartate (NMDA) receptor antagonist MK-801, whereas the non-NMDA receptor antagonist NBQX, acetoacetate, vitamin E, and PBN showed partial protection.

These results support the concept of developing oxygen free radical scavengers for both AD and PD and further suggest that inhibition of NOS and blockade of NMDA receptor function may alter progression of idiopathic PD.
In brain microdialysis in awake rats, striatal 'OH output increased 3-5-fold after infusion of methylpyridinium ion (MPP+), a complex I inhibitor, or sodium azide, a complex IV inhibitor.

Superfused rat cerebral cortex slices were submitted to a continuous electrical (5 Hz) stimulation and treated with sodium azide (1-10 mM) in the presence of 2 mM 2-deoxyglucose ("chemical ischemia").
After restoring normal superfusion conditions, acetylcholine release recovered to 70+/-3.1% of the controls; the N-methyl-D-aspartate receptor antagonist MK-801 (10 microM) as well as the nitric oxide scavengers, haemoglobin (20 microM) and 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-l-oxyl-3-oxide (150 microM), improved the recovery in presynaptic activity, showing that both glutamate and nitric oxide play detrimental roles in chemical ischemia.

All CI/REP-induced effects were prevented by the NMDA receptor antagonist MK-801, 10 microM, suggesting the involvement of glutamate.
In superfused, electrically stimulated rat cerebral cortex slices, chemical ischemia (CI) was induced by a 5-min treatment with the mitochondrial toxin, sodium azide (10 mM), combined with the glycolysis blocker, 2-deoxyglucose (2 mM).

The chemical hypoxia induced by mitochondrial toxins produces a secondary excitotoxicity, leading to the activation of N-methyl-D-aspartate receptors.

In addition, the NO precursor L-arginine (5x10 (-4) M) as well as the NO donors sodium nitroprusside (SNP; 1 microM) and sodium azide (NaZ; 10 microM) were able to revert the effect of L-NAME returning the amplitude of naloxone-induced contracture to the same level in control morphine-dependent ilea.
We also demonstrated that the competitive NMDA receptor antagonist DL-2-amino-5-phosphonovaleric acid (AP-5; 50 microM) potently reduced the amplitude of naloxone-induced contracture in the same model, an effect that was reversed by co-administration of the excitatory amino acid L-glutamate (40 microM).

A change in pHo (8.2 or 6.6), or addition of NMDA and non-NMDA receptor antagonists (D-AP5 and CNQX) in combination, significantly reduced the increase in [Ca2+] i, pointing to a protective effect of extracellular alkalosis or acidosis, and involvement of excitatory amino acids.

All the above effects depended on glutamate release and consequent NMDA receptor activation, since the NMDA antagonist MK-801 (1 microM) prevented them, and the spontaneous efflux of [(3) H]-d-aspartate from superfused neurons was concentration-dependently increased by NaN (3).

The sigma receptor agonist, 1,3-di-o-tolyl-guanidine (DTG), was shown to depress [Ca (2+)](i) elevations observed in response to ischemia induced by sodium azide and glucose deprivation.
