Quantitative and qualitative biochemical parameters for alcohol abuse.

Blood from alcoholics, non-alcoholic patients and healthy controls were analyzed for various biochemical markers. Follow-up measurements were made during about 3 months of abstention. While a gradual increase in aldehyde dehydrogenase activity (ALDH) in red cell was noted in alcoholic patients serum alpha 1-acid glycoprotein (AAG) values returned to normal range within 8 weeks during abstinence. An additional minor band for alpha 1-antitrypsin (AAT) was observed after isoelectric focusing of sera from alcoholics; this band disappeared after 3 weeks of abstinence. However, no such unusual AAT band was found in non-alcoholic patients with liver disorders.
