The responses to acidic hypercapnia (PCO2 = 50-60 Torr, pH = 7.20-7.10), hypoxia (PO2 = 25 and 50 Torr), perfusate flow interruption, and bolus injections of sodium cyanide (20-40 nmol) were tested.

9017669 Doolette DJ: Mechanism of adenosine accumulation in the hippocampal slice during energy deprivation. Neurochem Int. 1997 Feb;30(2):211-23.

The mechanism by which adenosine accumulates in the hippocampal slice during energy deprivation was investigated by examining the adenosine A1 receptor mediated depression of synaptically evoked field potentials in the CA1 area.
Blocking of the mitochondrial electron transport chain with 200 microM sodium cyanide or mitochondrial uncoupling with 50 microM 2,4-dinitrophenol both produced a rapid depression of synaptic transmission that was antagonised by 1 microM 8-cyclopentyl-1, 3-dimethylxanthine, an adenosine A1 receptor antagonist.

The evoked population spike (PS) was extracellularly recorded in the CA1 pyramidal cell layer after stimulation of the Schaffer collaterals.
When superfusion ACSF contained 20 mM glucose with or without 1 mM sodium cyanide (NaCN), after 60 min reoxygenation the evoked PS completely recovered even following 120 min anoxia.

Perforated whole-cell patch clamp and fluorimetric techniques were combined to examine changes in membrane currents, intracellular calcium ([Ca2+] i) and mitochondrial potential (DeltaPsim) in neurons dissociated from the CA1 subfield of the hippocampus of young rats. 2.

A significant decrease in the rate of proton secretion in the presence of the carbonic anhydrase inhibitor ethoxzolamide indicates that the second major route for the release of protons includes carbonic anhydrase activity and the diffusion of CO2.

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).

Addition of an inhibitor or an uncoupler of mitochondrial respiration [sodium cyanide (5 X 10 (-3) M) or dinitrophenol (5 X 10 (-4) M), respectively] in the perfusate caused significant decreases in reoxygenation-induced tissue Ca2+ gain.
