Increased activity of monoamine oxidase by epoxy resin hardeners

Abstract In order to investigate the potency of amines to cause metabolic changes which are related to scleroderma, serum monoamine oxidase (MAO) activity to workers in an epoxy resin handling process was measured. Mean serum MAO activity of 15 workers exposed to amine was 33.5 ± 6.4 units, whilst that of control workers was 28.9 ± 7.8 ( P
