title: [Comparative study of neurophysiological effects of adamantane derivatives in the experimental parkinsonism model].
abstract: The activity of the adamantane derivative PK-Merz and the new aminoadamantane derivative hemantane was studied by methods of electromyography and electroneuromyography in rats with a model of Parkinson syndrome induced by the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). The toxin produced an increase in the pulse conduction velocity (PCV) in the motor fibers of peripheral nerves and a decrease in the amplitude and frequency of the maximum muscle stress curve. A singe administration of both PK-Merz and hemantane produced unidirectional changes in the neuromyographic parameters and reduced the PCV down to a level in the control group. These results give ground for the clinical investigation of hemantane.
