Glutathione peroxidase is an enzyme that couples the oxidation of reduced glutathione to the detoxification of peroxides. Alterations in the activity of this component of the glutathione oxygen scavenging system in brain have been reported in several conditions associated with oxidative challenge and/or cellular damage. We measured the activity of(More)
Glutathione peroxidase is an enzyme of major importance in the detoxification of peroxides in brain. Using the spectrophotometric procedure of Paglia and Valentine [8] and Beutler [2] we measured the activity of this enzyme in autopsied brain from 12 patients dying with idiopathic Parkinson's disease and 11 neurologically normal adults matched with respect(More)
Four growth studies were conducted to determine the signs, biochemical indices and histopathology of a thiamin deficiency and the thiamin requirement of young rainbow trout reared at 15°C on a semi-purified test diet. The major overt signs of a thiamin deficiency in rainbow trout are predominantly neurological: irritability and instability. Other signs(More)
The neurochemical markers for the major neurotransmitter systems were measured in the brain of a patient who died with a dementia-parkinsonism-motor neuron disease (DPMN) syndrome complex. Moderate neuronal loss in the substantia nigra, spongiform changes in the frontal cortex, and moderate anterior horn cell loss throughout the spinal cord were observed. A(More)
We measured the activity of choline acetyltransferase, the cholinergic marker enzyme, in the brains of 17 patients from five established pedigrees with dominantly inherited olivopontocerebellar atrophy (OPCA). OPCA is a group of cerebellar ataxia disorders in which serious intellectual impairment is not typically considered to be an accompanying feature.(More)
