Sustained convulsive seizures were induced with bicuculline in newborn rabbits and marmoset monkeys. In both species, seizures were predominantly tonic, with generalized polyspikes on the EEG. Brain glucose concentration fell dramatically during seizures in both species, and in many normoglycemic
Heterogenous stock mice in addition to mice selectively bred to maximally differ in their severity of alcohol withdrawal seizures (withdrawal seizure-resistant (WSR) and withdrawal seizure-prone (WSP] were used to provide evidence in favor of the importance of the rapidly changing distribution of
During seizures, glucose concentrations are high in the hippocampus. Mitochondrial hexokinase (HK) catalyzes the first essential step of glucose metabolism and directly couples extramitochondrial glycolysis to intramitochondrial oxidative phosphorylation. The neuroprotective effects of an HK
OBJECTIVE
In a family with congenital hyperinsulinism (HI), first described in the 1950s by McQuarrie, we examined the genetic locus and clinical phenotype of a novel form of dominant HI.
METHODS
We surveyed 25 affected individuals, 7 of whom participated in tests of insulin dysregulation (24-hour
Marked asterixis occurred in two patients following metrizamide myelography. One also suffered generalized seizures and the other had severe stuttering speech for seven days. The spectrum of toxic manifestations of metrizamide is reviewed with emphasis on the unusual lethargy and other depressive
In Mongolian gerbils (Meriones unguiculatus) cerebral ischemia was produced by occlusion of the right common and the left external carotid arteries. Gerbils were classified according to their neurological appearance as "symptom-negative" (8 animals), "mild symptoms" (unilateral hemiparesis, 10
Temporal lobe epilepsy is a common form of adult epilepsy and shows high resistance to treatment. Increasing evidence has suggested that metabolic dysfunction contributes to the development of seizures, with previous studies indicating impairments in brain glucose metabolism. Here we aim to
A method to monitor extracellular glucose in freely moving rats, based on intracerebral microdialysis coupled to an enzyme reactor is described. The dialysate is continuously mixed with a solution containing the enzymes hexokinase and glucose-6-phosphate dehydrogenase, and the fluorescence of NADPH
The intraperitoneal (IP) treatment of rats with diazinon (40 mg/kg) resulted in a variety of changes in the brain. Glycogen was depleted, but there was an increase in the activities of glycogen phosphorylase, phosphoglucomutase, hexokinase, lactate dehydrogenase, and fructose 1,6 diphosphatase. The
Effect of diazinon (10,20 and 40 mg/kg, i.p.) on the level of blood glucose in rats was investigated. Hyperglycaemia peaked 2 h after i.p. treatment with 40 mg/kg diazinon. The cerebral acetylcholinesterase activity was significantly reduced. The blood level of pyruvic acid was unchanged while that
Two cases of absence status are described, one case following metrizamide myelography and the other from omnipaque myelography. Metrizamide has been well known to cause convulsive seizures even in patients without epilepsy. The exact mechanism is not known but appears to be direct neuronal toxic
Dysfunction of glucose transporter 1 (GLUT1) proteins causes infantile epilepsy, which is designated as a GLUT1 deficiency syndrome (GLUT1DS; OMIM #606777). Patients with GLUT1DS display varied clinical phenotypes, such as infantile seizures, ataxia, severe mental retardation with learning
