The influence of activator of ATP-sensitive potassium channels (KATP) pinacidil and blocker glibenclamide after intermittent hypoxia in rats under stress condition on ADP-stimulated mitochondrial respiration by Chance and lipid peroxidation processes in liver have been investigated. We used next substrates of oxidation--0.35 mM succinate, 1 mM alpha-ketoglutarate, 3 mM glutamate, 3 mM pyruvate, 2.5 mM malate and inhibitor of the mitochondrial fermentative complex I (10 microM rotenone), succinate dehydrogenase inhibitor (2 mM malonate) and inhibitor of transamination (1 mM aminooxiacetate). We suggest that adaptation by intermittent hypoxia and application of a KATP opener pinacidil possess significant protective effect on mitochondrial energy support under stress condition. Combination of intermittent hypoxia with pinacidil causes more efficient consumption of oxygen and decrease of lipid peroxidation processes comparative to intermittent hypoxia or pinacidil injection used separately. We conclude about the existence of the functional link between nitric oxide which is being increased under intermittent hypoxia and KATP opener. Both intermittent hypoxia and pinacidil effectively decrease the negative results of mitochondrial dysfunction under stress condition.
