Cardiac glycoside receptors in clinical and experimental states of chronic renal failure.
To investigate the mechanisms leading to decreased cardiac glycoside sensitivity in uremia, digitalis receptors were characterized by [3H]-ouabain binding to mononuclear leucocytes of chronically hemodialyzed patients and to cerebral cortex membranes of partially nephrectomized rats. There were no statistically significant differences in receptor density and affinity between uremic patients and healthy control persons and between partially nephrectomized and sham operated rats. [3H]-Ouabain bound with high affinity to intact mononuclear leucocytes and to cerebral cortex membranes. However, the affinity to the cerebral cortex membrane preparation was markedly higher.
