THE EFFECTS OF DEPRENYL AND 1-METHYL-4-PHENYL-1, 2, 3, 6-TETRAHYDROPYRIDINE (MPTP) ON 2-DEOXYGLUCOSE UPTAKE IN THE MOUSE BRAIN 总被引:1,自引:0,他引:1
~3H-2-deoxyglucose (2-DG) autoradiographic technique was used to study the ef feets of a monoamine-oxidase-B (MAO-B) inhibitor deprenyl and the neurotoxin Ⅰ-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) on 2-DG uptake in the mouse brain. Following MPTP intoxication, 2-DG uptake was increased in the substantia nigra and lo(?)us ceruleus. At the same time, obvious abnormal behavior of the animals was induced. In the mice pretreated with deprenyl, 2-DG uptake was similar to that of control animal. Ab normal behavior. though present, was significantly milder than in mice given MPTP alone. It is concluded that MPTP interferes with the glucose metabolism in the substantia nigra and locus ceruleus and induces remarkable abnormal behavioral syndrome of mice. These deleterious effects can be blocked by pretreatment with deprenyl. 相似文献
