The authors found that the phosphororganic pesticide neguvon in a dose of 200 mg/kg of body weight diminished the content of dopamine in the striatum of white rats. This effect was increased after daily administration of the same dose for a period of 5 days. The reactivator of cholinesterase TMB-4(Trimedoxime) and H-choline blocker tropacine prevented this effect. They discussed the connection between the changes in the content of dopamine and modulating role of presynaptic choline receptors of H- and M- types in the dopaminergic terminals of the striatum.
