In the rat, zitter (zi) and tremor (tm) are autosomal recessive mutations that in homozygotes caused curled whisker hair, and tremor when the animals move. In both mutant types, the presence of many vacuoles gives the central nervous system a spongy appearance. The mutants differ sharply in one
BACKGROUND
Epileptic seizures are associated with motor, sensory, somatosensory or autonomic symptoms that have all been described in varying detail over the years. Of interest in the present report is a case of normal physiological tremor, which to date has never been evaluated prior to and during
Tremor rats (tremor homozygous rats) exhibit spontaneous absence-like seizure, which is characterized by a sudden immobility with staring and the appearance of 5- to 7-Hz spike and wave complexes in cortical and hippocampal electroencephalogram (EEG). In this study, we examined the development of
The present behavioral study was undertaken to investigate whether neuronal nitric oxide (NO) synthase mediates the abnormal consequences of increased NMDA receptor-mediated synaptic transmission in models of postural tremor, Parkinson's disease and epilepsy. We used 7-nitroindazole, a selective
Neurological manifestations of thyroid autoimmunity are heterogeneous and nonspecific. The most frequently adopted name for this entity is Hashimoto's encephalopathy although this eponym has been recently contested. In the absence of specific clinical features, diagnosis is suggested by the presence
Levofloxacin-induced-neurological adverse events such as convulsion, involuntary movement (tremor, myoclonus and chorea-like) and visual hallucination in two elderly patients are reported. A 67-year-old man with minor alcoholism and a past-history of gastrectomy and cholecystectomy was given 300
Tremor rats begin to exhibit clinical or electrical absence-like seizures after 6 weeks of age, and by 14 weeks of age, all have seizures. Central-type benzodiazepine receptor binding was investigated in tremor rats and control rats, aged 4 weeks and 16 weeks. Significantly lower benzodiazepine
Lyme borreliosis is a multisystem disorder caused by Borrelia burgdorferi (Bb). Neurological symptoms such as lymphocytic meningoradiculoneuritis (Bannwart's syndrome), cranial neuritis (II,III,IV,V,VI), encephalitis, transverse myelitis are found in about 10% of cases during the second phase of the
Cerebrovascular permeability to protein (CVP-p) was assessed in rats following the systemic injection of either kainic acid (KA) or harmaline. The extravasation of a foreign (horseradish peroxidase, HRP) or an endogenous (rat immunoglobulin G, IgG) tracer protein was determined using
We report here four patients with acute leukemia, who developed seizure or tremor following treatment with imipenem, a new broad-spectrum antibiotic. All four patients had no renal dysfunction and recovered after discontinuation of the drug. Two patients who developed seizure had a past history of
Fifteen beta-carboline derivatives, including those found in the South American hallucinogenic plant Banisteriopsis caapi, were injected IP and IVC into mice. Subsequent behavioral changes were observed and the levels of the compounds in brain tissue were determined. It was found that following IP
Compounds from both the beta-carboline (BC) and xanthine groups have been suggested to be the natural ligands for benzodiazepine (BZ) receptors. In this study we examined the effects of several BC's and caffeine, 1,3,7-trimethylxanthine, on the binding of 3H-flunitrazepam (3H-FZ) and
Tremor and seizures developed in a 2-year-old girl receiving total parenteral nutrition. T1-weighted images on MRI revealed areas of hyperintensity in the basal ganglia, brainstem and cerebellum. Blood manganese was elevated. The symptoms and MRI abnormalities disappeared after withdrawal of
Immunoreactive- (IR-) somatostatin (SRIF), neuropeptide Y (NPY) and corticotropin-releasing factor (CRF) contents were investigated in the brain of tremor rats with absence-like seizure and spontaneously epileptic rats (SER), which is a genetically defined double-mutant (zi/zi, tm/tm) obtained by
We examined the effects of conventional antiepileptic drugs (AEDs) on absence-like seizures in homozygous tremor rats (tm/tm) to determine if they corresponded pharmacologically to human absence seizures and absence-like seizures in spontaneously epileptic rats (SER: zi/zi, tm/tm) with both tonic
