Background: In the organs that mediate alcohol effects on the human body and its health, the liver plays a particular important role. This study was designed to detect the changes of hepatic enzymes after alcohol intake and evaluate the corresponding damage to the human body.
Methods: Fifteen volunteers were included according to the criteria. After the intake of 80 g ethanol containing beverage, alcohol levels were detected and blood samples were collected at 0.5- to 3-hour interval to detect the levels of hepatic enzymes simultaneously.
Results: After the intake of 80 g ethanol, various symptoms occurred in volunteers while the concentration of blood alcohol peaked at 1 hour and normalized within 24 hours. The ratio of alanine aminotransferase (ALT) to aspartate aminotransferase (AST) increased significantly when the venous alcoholic concentration increased from 0 g/L to 1.2 g/L and the levels of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (gamma-GT) were elevated when the alcoholic concentration reached 0.4 g/L. No significant changes were noticed in ALT, AST or cholinesterase (CHE).
Conclusion: Acute alcohol intoxication may cause the changes of hepatic enzymes and prove the existence of reversible hepatic injury.
