title: Determination of aspartate aminotransferase isoenzymes in hepatic diseases--preliminary findings.
abstract: The study sought to establish a relationship between the AST isoenzyme levels in serum and degree of hepatic damage, by using a new and simple immunochemical method for the differential determination of the isoenzymes. Sixty-nine patients with various hepatic diseases were studied. During hepatic damage, cytoplasmic isoenzyme (s-AST) is found in greater quantities than mitochondrial isoenzyme (m-AST), but the m-AST level increases to a greater extent in acute liver diseases. However, m-AST in alcoholic hepatitis is higher than expected from the total AST (t-AST) values. The ratio of m-AST to t-AST seems to discriminate alcoholic hepatitis from other liver diseases.
