In the present experiment, male rats (15-17 months) were injected with deprenyl (0.25 mg/kg) three times per week for six months. At 21-23 months of age the male rats were sacrificed, the corpus striatum removed and superfused in vitro. Basal and…

In this report we describe some of the data on the capacity for estrogen to function as a neuroprotectant of the nigrostriatal dopaminergic (NSDA) system. The data show that estrogen (E) can alter two different response characteristics to NSDA…

The gonadal steroid hormone, estrogen, has the capacity to function as a neuroprotectant against methamphetamine (MA)-induced neurotoxicity of the nigrostriatal dopaminergic system within female, but not male, mice. In an attempt to understand some…

It has been demonstrated that the gonadal steroid hormone estrogen can exert neuroprotective effects upon the nigrostriatal dopaminergic (NSDA) system against methamphetamine (MA)-induced neurotoxicity in female, but not male, mice. In contrast, the…

A neurotoxic regimen of methamphetamine (MA-40 mg/kg ip) administered at 0 (control-MA vehicle), 0.5 and 72 h prior to determinations of striatal dopamine (DA) and DOPAC (3,4-dihydroxyphenylacetic acid)/DA ratios were compared among juvenile and…

Dimebon is an anti-histamine with central nervous system activity. In this report the effects of dimebon as a neuroprotectant in animal models of Parkinson's disease were tested as assessed in methamphetamine- and MPTP-induced striatal dopaminergic…

Rotenone is a commonly used pesticide that can function as an environmental neurotoxin. Rotenone is a known mitochondrial complex I inhibitor which can lead to oxidative stress and results in dopaminergic cell death. Another environmental factor…

In the present experiment we tested the effects of L-DOPA and amphetamine upon dopamine and DOPAC efflux in vitro from superfused corpus striatal tissue fragments of male rats who had been pretreated with reserpine. Male rats were treated with…

In the present experiment we tested the effects of L-DOPA upon dopamine (DA) efflux in vitro from superfused corpus striatal tissue fragments in medium containing reserpine. The purposes of this experiment were first, to evaluate the effects of…
