OBJECTIVE
Thiamine serves as a cofactor for several enzymes involved in brain function and neurotransmitters biosynthesis. Thiamine-dependent enzymes are important for oxidant stress defenses. Several studies have reported that thiamine deficiency in the central nervous system reduces seizure
Weanling mice of the DBA/2J strain are spontaneously audiogenically seizure prone between 19 and 24 days. Thereafter, susceptibility declines rapidly within the next 7-10 days. It was found that thiamine tetrahydrofurfuryl disulfide (TTFD) significantly delayed the natural disappearance of seizure
Many neurological disorders that occur frequently in lead intoxicated animals, have also been observed in thiamine deficient animals. To test whether lead intoxication could decrease the thiamine status and thresholds of electroshock seizure in rats, 3-week-old Wistar rats were treated with lead or
Twenty-three 2- to 5-month-old Beagle dogs were fed a purified thiamine-deficient ration (2 to 3 micrograms of thiamine/100 g of ration) at a rate of 40 to 70 g/kg of body weight/day depending on age. Eleven dogs were used as principles, 6 as pair-fed controls, and 6 as ad libitum-fed controls.
Rats were fed a thiamine-deficient diet for 4 weeks and injected daily with pyrithiamine during the last two weeks of the diet. This regime induced severe neurological anomalies such as ataxia, loss of righting reflex and visual place reflex, and finally full tonic-clonic seizures. These symptoms
A simple and rapid method based on the NADH-linked reduction of a tetrazolium dye was described for the determination of pyruvate dehydrogenase activity in rat brain homogenates. The method (method 3) gave a value of 36.06 +/- 1.24 nmol of pyruvate utilised/min/mg of whole brain protein. This value
Thiamine deficiency (TD) has been used as an experimental model in rodents to study the molecular mechanisms of neurodegeneration and its association with behavioral changes. The aims of the present study were to investigate the spatial cognitive performance of pyrithiamine-induced thiamine
We observed under light and electron microscopes morphological changes in the rat sciatic nerve during the last stages of a thiamine deficient state as induced by pyrithiamine (PT: 50 microgram/100g X 11 days) and thiamine deficient diet (TDD), in which rats experienced severe tetanic convulsions.
Clinical characteristics: Biotin-thiamine-responsive basal ganglia disease (BTBGD) may present in childhood, early infancy, or adulthood. Prompt administration of biotin and thiamine early in the disease course results in partial
Thiamine (vitamin B1 ) is an essential nutrient that significantly influences ATP production in the body. It needs to be supplemented consistently through an exogenous source to prevent deficiency; however, it is easily affected by a variety of mitigating factors. Additionally, thiamine
Thiamine (vitamin B(1)) is an essential component of a number of metabolic pathways and thiamine deficiency results in a progressive encephalopathy in both humans and animals. Confirming thiamine deficiency is problematic and relies on demonstrating reduced red blood cells transketolase activity, or
Subacute encephalopathy with seizures in alcoholics (SESA syndrome) is a rare disease entity following chronic alcohol ingestion. It is quite distinct from alcohol withdrawal syndromes, such as delirium, withdrawal seizures or CNS complications of alcohol, such as Wernicke-Korsakow syndrome, central
