Logáil Isteach / Cláraigh

Differential sensitivity to neurotoxic effects of methamphetamine on striatal dopaminergic neurones between C57BL/6 and BALB/c mice has been established. In the present studies, the interaction of methamphetamine-induced dopamine release, self-injurious behaviour, the neural immune response, and the

1-Adamantanamine (amantadine) pretreatment significantly reduced the motor hyperactivity and hyperthermia caused by d-amphetamine in reserpinized mice. In drug-naive mice, when amantadine was administered after d-amphetamine, the motor activity caused by the latter also was decreased. Since our

A 6-week-old male infant presented with 2 days of fever, emesis, and diarrhea, associated with episodic and chaotic rapid eye movements, determined to be opsoclonus. An electroencephalogram (EEG) obtained during the events was normal. He was treated empirically for meningitis, and an initial workup

A 10-year-old girl presented to her pediatrician with a history of cough and fever. A chest radiograph revealed a paraspinal mass. On cross-sectional imaging, the mass traversed the diaphragm, extending from T9 to L1 spinal levels with involvement of the T10-12 neural foramen. Vanillylmandelic and

Neonatal adrenal abscess is an extremely rare condition. 32 cases, 4 bilateral, have been described in the world literature. We treated successfully other two bilateral cases. We report on this rare condition and review the world literature. In our Department we observed two patients in the neonatal

We systematically paired auditory, olfactory, and social stimuli with each injection of morphine in rats. We found that, when morphine was kept constant at a low dose, the external stimuli acquired the property of a conditional stimulus (CS) to cause hyperthermia which was antagonized by naloxone.

Hypothalamus - Response to early paracetamol exposure in male rats offspring.

One of the reasons for using paracetamol during pregnancy is fever. The brain structure responsible for maintaining proper body temperature, but also for controlling some endocrine aspects is hypothalamus. In this study we examined the effect of early pretreatment of paracetamol on hypothalamic

Methamphetamine generates peroxynitrite and produces dopaminergic neurotoxicity in mice: protective effects of peroxynitrite decomposition catalyst.

Methamphetamine (METH)-induced dopaminergic neurotoxicity is believed to be produced by oxidative stress and free radical generation. The present study was undertaken to investigate if METH generates peroxynitrite and produces dopaminergic neurotoxicity. We also investigated if this generation of

Newborn mice were inoculated with attenuated Coxsackie type B4 virus. Three-to-4-day old mice were infected with yellow fever virus vaccine. A number of mice survived the acute infections. Some of these demonstrated residual neurological symptoms, some showed recovery from symptoms while others

Effect of melatonin on methamphetamine- and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced dopaminergic neurotoxicity and methamphetamine-induced behavioral sensitization.

Methamphetamine (METH)- and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced dopaminergic neurotoxicity is thought to be associated with the formation of free radicals. Since evidence suggests that melatonin may act as a free radical scavenger and antioxidant, the present study was

OBJECTIVE Stressful life events play an important role in the aetiology of human mood disorders and are frequently modelled by chronic social defeat (SD) in rodents. Exploratory phenotype in rats is a stable trait that is likely related to inter-individual differences in reactivity to stress. The

Methamphetamine (METH) is one of the major drugs of abuse that is postulated to cause neurotoxicity by depleting dopamine (DA) and its metabolites, high-affinity DA uptake sites, and the activity of tyrosine hydroxylase. The present study was undertaken to investigate whether the relatively
