Introduction: Beta-glucuronidase (GLU) is a member of the lysosomal glycosidase family that catalyzes hydrolysis of β-D-glucuronic acid residues from the non-reducing end of glycosaminoglycans. Increased activities of GLU have been earlier reported in the serum of alcohol-dependent patients after a chronic heavy drinking period but not after acute intoxication (called binge drinking). The accelerating binge drinking pheno-menon is an alarming public health issue that requires better prevention. Purpose: To determine the activity serum and urinary GLU, after an acute, single, and a large dose of alcohol intoxication. Materials and methods: The serum and urine of eight healthy binge drinkers were collected before binge drinking, and 2 and five days after the drinking session. The activity of GLU was determined by the colorimetric method. Results: There was a tendency to decrease in the serum GLU activity two days after acute alcohol intoxication (binge drinking), which was followed by the significant increase in the GLU activity five days after drinking. The urinary activity of GLU was not changed after intoxication. Conclusion: Alcohol-induced imbalance in the serum GLU activity might be associated with alcohol-induced liver hypoxia and subsequent reperfusion, and can be detected even five days after the drinking session.
