The specific [3H]‐ouabain binding to microsomal fractions derived from cat heart, liver, spleen, and kidney increased significantly following chronic administration of ethanol.

Since ouabain binds exclusively to cell membrane (Na+ + K+)‐adenosine triphosphatase ((Na+ + K+)‐ATPase), these results provide evidence for an increase in number of (Na+ + K +)‐ATPase macromolecules during chronic alcoholism.

The importance of the increase in number of (Na+ + K+)‐ATPase molecules in the adaptive increase in ethanol metabolism and cardiac myopathy in chronic alcoholism is discussed.
