Neurotoxicity of the meperidine analogue N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine on brain catecholamine neurons in the mouse. 1984

H Hallman, and L Olson, and G Jonsson

The effect of N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (NMPTP) on central monoamine neurons in mice was investigated using histo- and biochemical techniques. NMPTP (2 X 10 mg/kg i.v.) produced a rapid and long-lasting reduction (-30%) of striatal dopamine, while the dopamine levels were only transiently reduced in mesencephalon and frontal cortex. HVA and DOPAC were initially markedly reduced (-50 to -70%) in striatum while a marked recovery was found in the chronic stage. NMPTP also induced a long-term reduction of noradrenaline in striatum and frontal cortex while 5-hydroxytryptamine and 5-HIAA levels were essentially unaltered. The data indicate a neurotoxic action of NMPTP on both dopamine and noradrenaline nerve terminals in mouse brain.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
