Parkinson's disease is characterized by a depletion of dopamine (DA) neurons in the nigrostriatal pathway. Stereotaxic injections of 6-hydroxydopamine (6-OHDA), a selective neurotoxin, into either the medial forebrain bundle or the substantia nigra result in a massive DA denervation of the nigrostriatal pathway. Following unilateral nigrostriatal DA depletion, hemiparkinsonian animals develop a...

The present study was a protocol for investigation of the effect of acetaminophen (i.p.) on pain induced by electrical stimulation. We used tail shock vocalization (TSV) test for measurement of the pain. In this test, the animals were restrained and stimulated by two electrode implanted on the middle of the animal’s tail. The latency from stimulation of the tail till vocalization of the animal ...

We report on an experimental study of slow pulse propagation and polarization storage of light in an atomic vapour for pulse durations ranging from several μs to 100 μs, for non-zero magnetic fields, for temperatures ranging from 65 to 90 ◦C and for two different rubidium isotopes. The results confirm the presence of the electromagnetically induced transparency window as predicted by Lukin (199...

The effects of gonadectomy on amphetamine-induced rotational behavior were studied in male and female rats. Different systemic doses were used to produce equivalent brain concentrations of the drug in each group, thereby controlling for sex differences in the metabolism of amphetamine. Ovariectomy of female rats significantly attenuated amphetamine-induced rotation, whereas castration of males ...
