Stem cell transplantation was introduced as a mean of cell replacement therapy, but the mechanism by which it confers clinical improvement in experimental models of neurological diseases is not clear. Here, we transplanted neural precursor cells (NPCs) into the ventricles of mice at day 6 after induction of chronic experimental autoimmune encephalomyelitis(More)
Multiple sclerosis is no longer considered to simply be an autoimmune demyelinating disease. Axonal destruction is another central pathological feature and a contributor to the accumulating disability of disease progression. The mechanism underlying axonal pathology has not been fully clarified but does not appear to be a simple one. The relationship(More)
The frequency of multiple sclerosis (MS) in Greece is still debated. Our previous epidemiological field survey with a cross-check study of MS on March 31, 1984, in the province of Evros in north-eastern Greece showed a prevalence rate of 10.1/100,000. In 1990, Milonas et al. recorded a prevalence rate of 29.5/100,000 in northern Greece. So Greece is(More)
The present study aimed at producing a chronic model of focal epilepsy in rabbits. In group A (30 rabbits) 0.05 ml alumina gel was injected in the right sensorimotor cortex, while in group B (10 rabbits) normal saline was injected in the same region. The observation period lasted 70 days. All group A animals developed spontaneous focal or focal initiated(More)
Sleep deprivation is known to be one of the principal mechanisms to activate epileptogenic activity in the EEG recording and indeed it is one of the most common activation techniques in EEG practice. It is generally recognized that about one third of patients with seizures presenting a normal or borderline normal routine EEG may be expected to exhibit an(More)
We report serial MR findings in a 54-year-old woman with eosinophilic meningoencephalitis due to Toxocara canis infection, a parasitic disease contracted through exposure with soil contaminated by the eggs of the roundworm. MR imaging revealed several enhancing subcortical and white matter lesions in both lobes. Antihelminthic chemotherapy yielded marked(More)
Thyroid hormone deficiency is frequently associated with central nervous system (CNS) disturbances such as mental retardation, convulsions, coma etc. Studies of quantitative changes in CNS in hypo- or hyperthyroidism are scarce. Evoked potentials is a good method of assessing the electrical response of the brain to different (visual, acoustic,(More)
sive alternative to glycopeptides for the treatment of MRSA infections. Data from the United States and Europe have shown that vancomycin-intermediate S. aureus isolates also remain susceptible to some of the conventional antimicrobial drugs, including co-trimoxazole (5). If their efficacy in vivo is validated by clinical trials , use of these conventional(More)
