RESUMO

BACKGROUND: The effects of chemical products on the nervous system have been studied by various scientists. In this work, the antiparkinsonian action of a water-soluble form of harmine hydrochloride was studied. The present studies aim to research antiparkinsonian action of the harmine hydrochloride original compound. METHODS: To achieve the objective of the study, the authors used haloperidol-induced catalepsy and a method of Parkinson's syndrome (PS) induced by the MPTP (the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) neurotoxin. The experiments were performed on rats and mice which were divided into groups of 10 animals. RESULTS: It was established that harmine hydrochloride (HH), at a certain dose, eliminated haloperidol-induced catalepsy in rats and reduced oligokinesia and rigidity in the parkinsonism test in mice. Seven days after the experiment, the authors found the presence of rigidity in animals which had received the neurotoxin. It manifested itself in a shortened stride length compared to this parameter in intact controls. CONCLUSIONS: During the study the efficacy of harmine hydrochloride was equivalent to the effects of levodopa at a certain dose, which suggested that harmine hydrochloride compensated dopamine deficiency in the brain.
