OBJECTIVE
Oxidative damage has been implicated in the pathogenesis of cerebral ischemia. We previously demonstrated that exogenously supplied dehydroascorbic acid (DHA), an oxidized, blood-brain barrier transportable form of the antioxidant ascorbic acid (AA), improves outcome after experimental
Less than 8.5% of ischemic stroke patients receive clot-busting drugs within the narrow time needed to reduce injury. Thus, there is need for an easily-accessible delayed post-stroke drug treatment to improve functional recovery. Various combinations of fluoxetine, simvastatin, and ascorbic acid
The main symptoms of stroke such as a displacement of intracranial structures, changes in spatial relations, secondary hemorrhagic and ischemic foci, oedema and metabolic disturbances are the cause of the disorders of hypothalamus-hypophysis system leading to increased secretion of corticosteroids
We compared ascorbic acid (AA) levels in the blood and TPA- and fMLP-stimulated superoxide (O(2)(•-)) production in neutrophils of pre-, early, and late hypertensive stroke-prone spontaneously hypertensive rats (SHRSP) with those of age-matched Wistar Kyoto rats (WKY), or two other normotensive
Delayed treatment of stroke with recombinant tissue plasminogen activator (r-tPA) induces overexpression of matrix metalloproteinase 9 (MMP-9) which leads to breakdown of the blood-brain barrier (BBB) and causes more injuries to the brain parenchyma. In this study, the effect of ascorbic acid (AA),
A condition of oxidative stress is known to occur in ischemic stroke, the current therapeutic intervention of which is largely limited to thrombolysis. To assess the effect of vitamin C - in conjunction to aspirin - in ischemic stroke-related lipid peroxidation, we measured plasma levels of
Changes in the concentration of the lipid peroxidation products in the blood of 152 patients in stroke were studied. 18 patients with LPO processes activation received supplementary treatment with antioxidant preparation (tocopheroli acetas, ascorbic acid, pyridoxalphosphate, glutaminic acid), which
Tissue plasminogen activator (tPA) thrombolysis remains the gold standard treatment for ischemic stroke. A time-constrained therapeutic window, with the drug to be given within 4.5 h after stroke onset, and lethal side effects associated with delayed treatment, most notably hemorrhagic
To examine the relation between serum ascorbic acid level and the prevalence of cardiovascular disease, we analyzed data from 6,624 U.S. men and women enrolled in the Second National Health and Nutrition Examination Survey. We calculated odds ratios and 95% confidence intervals to estimate the
OBJECTIVE
To test whether supplementary antioxidants immediately following acute ischaemic stroke will enhance antioxidant capacity and mitigate oxidative damage.
METHODS
A randomised controlled trial.
METHODS
A university teaching hospital.
METHODS
A total of 48 acute ischaemic stroke patients
New effective strategies and new highly effective neuroprotective agents are being searched for the therapy of human stroke and cerebral ischemia. The compound SMe1EC2 is a new derivative of stobadine, with enhanced antioxidant properties compared to the maternal drug. Carvedilol, a non-selective
Effect of L-ascorbic acid 2-[3,4-dihydro-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-2H -1- benzopyran-6yl-hydrogen phosphate] potassium salt (EPC-K1, CAS 127061-56-7), a diester of alpha-tocopherol and ascorbic acid, on transient cerebral ischemia was studied in Mongolian gerbils. Cerebral
