  • Title: [The part of Na+K+-ATPase in total energy consumption in slices of brain and kidney cortex as well as in reticulocytes: a damaging effect of ouabain on brain cells].
    Author: Zimmermann C, Rapoport SM.
    Journal: Acta Biol Med Ger; 1982; 41(11):1029-35. PubMed ID: 6303028.
    Abstract:
    A progressive inhibition of the respiration of brain cortex slices by ouabain (0.2 mM) is not only caused by a specific inhibition of the Na+K+-ATPase, but is also due to damage of the cell membrane. It involves efflux and degradation of NADH or NAD. In contrast, the respiration of kidney cortex slices and reticulocytes exhibits only a rapid and constant inhibition by ouabain in concentrations of 0.2, 0.5 and 1.0 mM, respectively. Ouabain causes a decrease in O2-consumption of 12%, 45% and 23% in reticulocytes, slices of kidney cortex and brain cortex, respectively.
