title: Rat cortex synaptic and nonsynaptic mitochondria: enzymatic characterization and pharmacological effects of naftidrofuryl.
abstract: In order to investigate the in vivo pharmacological effects of the drug naftidrofuryl, we prepared populations of synaptic and nonsynaptic mitochondria from rat brain cortex. In these different mitochondrial populations the activities of citrate synthase, malate dehydrogenase, total NADH cytochrome c reductase, cytochrome oxidase, and glutamate dehydrogenase were evaluated. Except for glutamate dehydrogenase, the specific activities of the enzymes evaluated in the "free" mitochondrial fraction were higher than those observed in the "synaptic" SM1 and SM2 mitochondrial fractions, the difference between SM1 and SM2 fractions being significant. The in vivo administration of naftidrofuryl induced few and different changes in the various mitochondrial populations.
