SERUM MONOAMINE OXIDASE ISOENZYME DETERMINATION——A PRELIMINARY EVALUATION IN THE DIAGNOSIS OF LIVER DISEASES / 重庆医科大学学报

Suerm monoamine oxidasa isoenzymes (MAOi) were determined in 105 cases of liver disea ses and 49 normal controls.MAOi were separated into 3 bands (I. Ⅱ.Ⅲ) by polyacrylamide gel elcctrophoresis. The results revealed that MAOi Ⅲ% was increased in chronic liver diseases, especially in liver cirrhosis. Our findings suggest that serum MAOi determination is more sensitive than serum albumin, MAO, ChE, and ADA determinationsin in the early diagnosis of liver cirrhosis
