Abstract:
Aldehyde dehydrogenase (ALDH) V-A isozymes in saliva were detected in 96 patients with or without liver disease in order to clarify the relationships of the presence or absence of ALDH V-A isozymes to the metabolism of acetaldehyde (Ac-CHO) and alcoholic liver disease. The incidence of ALDH V-A deficiency was not different between the patients with alcoholic liver disease and those with non-alcoholic liver disease, nor between the patients with liver disease and without liver disease in no relation to alcohol misuse. Ac-CHO metabolism was not different between ALDH V-A deficient and non-deficient patients even in the ALDH I-deficient patients. These results indicated that ALDH V-A isozymes play virtually no role in the metabolism of Ac-CHO and its deficiency is not related to the development of alcoholic liver disease.
