Drug interactions on spontaneous locomotor activity in rats. Neuroleptics and amphetamine-induced hyperactivity.

abstract：:Substance P, administered intrathecally in the lumbar area of paraplegic rats activated the electromyogram (EMG) of the hindlimbs. This effect was markedly enhanced by previous denervation by 5,7-dihydroxytryptamine. Stimulation of the motoneurons by substance P was followed by a blunted response to the excitatory sub...

abstract：:In several strains of mice: Swiss CD1, BALB, DBA2, C57, the mixed D1/D2 direct dopamine receptor agonist, apomorphine, elicited a marked and virtually similar hypothermic effect. By contrast, in C3H mice, this effect was obviously less and shorter. Similarly, the hypothermic effects of two direct D2 dopamine agonists ...
