title: [Effects of piracetam on Na(+)-K(+)-ATPase and monoamine oxidase in rat brain and its antioxidation effect].
abstract: Piracetam, ig 600 mg.kg-1.d-1 for 30 d, caused a 20% decrease in the activity of Na(+)-K(+)-ATPase and monoamine oxidase (MAO) in vivo. In vitro, it presented an inhibitory effect on MAO, but had no direct effect on Na(+)-K(+)-ATPase at a concentration of 100 mmol.L-1. Piracetam had a potential action in scavenging free radicals. This action may be related to its clinical effects on amnesia and Alzheimer's disease.
