[Early detection of alcoholic liver cell damage by the fructose stress test].

After regular intake lasting for years also a relatively slight quantity of alcohol may cause liver lesions, so that also for so-called social habitual drunkards an endangering can be taken into consideration. The fructose tolerance with the hyperlactaemia connected with this seems to be suitable for the early recognition of the liver cell lesions, since first intracellular metabolic disturbances can be proved.
