Abstract
Peroral galactose tolerance tests with and without ethanol intake were performed on pregnant women with various clinical diagnoses, on women taking oral contraceptives and on control patients. The influence of ethanol on the rate of galactose elimination was normal in the control group and the group taking oral contraceptives. In half of the gravidae a diminished effect of ethanol on galactose elimination was observed. This indicates that in many pregnant women ethanol does not reduce the redox state of the liver.
