The effect of azoxymethane (AOM)-induced acute liver failure on brain extracellular K+ (A, measured with ISE in awake animals; B, measured photometrically in microdialysates ), 86Rb uptake in mice cortical slices (C), and brain extracellular Na+ (D, measured photometrically in microdialysates ) and lactate level (E, measured in microdialysates) and pH (F, measured with ISE in awake animals). The numbers of animals in experimental groups were 12–14 (A), 9 – 14 (B, D), 5 (C), 7–12 E, 10–16 (F)
