An Extra Isoenzyme Band of Serum Lactic Dehydrogenase in Patients with Acute Hepatitis and Cardiac Damage

Abstract

The abnormal fraction of lactic dehydrogenase (LDH) isoenzymograms in the sera of patients with acute hepatitis and/or cardiac damage is reported. Investigation showed that, adjacent to a normal LDH₅ (M₄) fraction, the abnormal fraction has apparent LDH activity.
According to its properties, the so-called extra LDH fraction seems to be alcohol dehydrogenase (ADH).
