serum monoamine oxidase isoenzyme

MAO is an extracellular enzyme with pyridoxal phosphate as a coenzyme. It is distributed in the mitochondria of liver and kidney tissues, and its distribution is liver > heart > kidney > brain > lung > skeletal muscle. MAO is also contained in platelets and placenta. There are three isoenzymes, which are from the anode to the cathode during electrophoresis. MAO-I, MAO-II and MAO-III have two subunits MAO-A and MAO-B. Basic Information Specialist classification: Digestive examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Rare. Normal value: MAOI: 28.3-36.3% MAOII: 44.3-53.3% MAOIII: 14.4-23.4% Above normal: Increased MAOI is seen in cirrhosis and chronic liver disease. Increased MAOII is seen in severe hepatitis and severe liver disease. Elevated MAOIII is seen in cirrhosis of the liver. negative: Positive: Tips: Individual serum monoamine oxidase activity is easy to passive, should be determined multiple times. Normal value Polyacrylamide gel electrophoresis (PAGE) MAOI 28.3% to 36.3%. MAOII was 44.3% to 53.3%. MAOIII was 14.4% to 23.4%. Clinical significance 1, MAOI increases liver cirrhosis, chronic liver disease. 2, MAOII raises severe hepatitis and severe liver disease. 3, MAOIII increased liver cirrhosis. High results may be diseases: liver cirrhosis, chronic hepatitis precautions Individual serum monoamine oxidase activity is easy to passive and should be determined multiple times. Inspection process Immediately after blood collection, the test method was determined by polyacrylamide gel electrophoresis. Not suitable for the crowd no. Adverse reactions and risks no.
