title: Xenobiotic enzyme profiles and Parkinson's disease.
abstract: Xenobiotic enzymic systems have been studied in Parkinson's disease. Platelet monoamine oxidase-B activity is increased by the use of phenylethylamine but decreased by the use of dopamine as substrate. Enzymes involved with sulfur oxidation and methylation are underactive.
