Erythrocyte abnormality in human myopathy.
Erythrocyte ghosts isolated from myopathic patients responded to 10(-4) molar ouabain with a dramatic increase in adenosine triphosphatase activity, while identical preparations from normal donors were inhibited by the same drug. These results have been interpreted in terms of a disease-related change in membrane integrity bearing upon function of the transport enzyme.
