摘要：
In rats with a unilateral 6-hydroxydopamine (6-OHDA)-induced lesion in the nigrostriatal fibers, methamphetamine (3 mg/kg, i.p.) induced Fos-like immunoreactivity (FLI), which was inhibited by pretreatment with N-methyl-D-aspartate antagonist MK-801 (1 mg/kg, i.p.), not only in the medial striatum contraiateral to the lesion but also in the substantia nigra pars reticulata (SNr) ipsilateral to the lesion. Thus, hemispheric asymmetries in FLI were induced by methamphetamine in the medial striatum and the SNr in the 6-OHDA model of turning which may be related to the altered function of glutamatergic transmission.
