The glutamate-glutamine cycle between neurons and glia is tightly related to excitatory glutamatergic and inhibitory GABAergic regulation in brain. The role of this neuron-astrocyte cross-talk on the neurotoxicity induced by amphetamines is not understood. Also, the impact of neurotoxic doses of amphetamines on the balance between glutamatergic and(More)
The aim of this study was to verify the effect of chronic exercise on the striatal dopamine (DA) outflow induced by low and high single doses of amphetamine (AMPH), and verify the existence of an exercise protective role on neurodegeneration. Adult male Sprague-Dawley rats were randomly separated into six groups: chronic exercise, saline; chronic exercise,(More)
Results of a double agar gel immunodiffusion (Ouchterlony) test that contained a polysaccharide (poly-B) antigen of Brucella melitensis strain B115 were compared with those of 5 other serotests. To determine the sensitivity and specificity of the immunodiffusion, standard tube, 2-mercaptoethanol, Rivanol, card, and complement fixation tests, sera obtained(More)
