Stroke is a third leading cause of death and oxygen free radicals have been shown to be involved in its pathophysiology. In the present study, we have investigated neuroprotective potential of trolox, a free radical scavenger in bilateral carotid arteries occlusion (5 min) model of global cerebral
BACKGROUND
One of the serious complications of stroke is memory impairment, which is considered as one of the complications of reperfusion of tissue. The present study was designed to compare the effect of administration of Trolox, carnosic acid and Human Chorionic Gonadotropin (HCG) immediately
The aim of our study was to examine gender differences of LDL- and HDL-cholesterol subfractions in patients after the acute ischemic stroke with focus on small LDL and HDL subfractions, and their association with oxidative stress markers. In addition, we have monitored the 7-day effect of
Major interest is currently focused on the development and evaluation of effective strategies for the pharmacological therapy of human stroke and cerebral ischemia, as well as some neurodegenerative disorders in which increased production of free oxygen radicals and the neurotoxic effect of
Many patients display elevated levels of serum cortisol following acute ischemic stroke. Given that glucocorticoids may potentiate some forms of insult, these studies examined the effects of corticosterone or dexamethasone exposure on cytotoxicity following oxygen-glucose deprivation in the
Baicalein is a flavonoid extracted from the root of Scutellaria baicalensis Georgi, a medicinal plant traditionally used in Oriental medicine. Among its biological activities, baicalein has been reported to exhibit antioxidant effects. Endothelin-1 (ET-1) is a potent vasopressor synthesized by
There is increasing interest in the emerging view that tea improves the antioxidant status in vivo and thereby helps to lower risk of certain types of cancer, coronary heart disease and stroke and its component biofactors could provide prophylactic potential for these diseases. The polyphenolic
Hypoxia (HYP) followed by reoxygenation (REOX) occurs frequently in the pathophysiology of the CNS. Free oxygen radicals (FOR) may participate in cerebral injury under such circumstances. Pharmacological control of the generation and/or subsequent effects of FOR by new effective compounds might
Hemin is cytotoxic, and contributes to the brain damage that accompanies hemorrhagic stroke. In order to better understand the basis of hemin toxicity in astrocytes, the present study quantified hemin metabolism and compared it to the pattern of cell death. Heme oxygenase-1 (HO-1) expression was
Excessive generation of free radicals is regarded as a major detrimental factor in cerebral ischemic insults. Neurons are particularly vulnerable to oxidative stress due to their limited anti-oxidant capacity. As an important source of antioxidants in the brain, astroglia are now thought to be
To explore the role of neurotrophin-3 (NT-3) during cerebral ischemia, NT-3-deficient brains were subjected to transient focal ischemia. Conditional mutant brains produced undetectable amounts of NT-3 mRNA, whereas the expression of the neurotrophin, BDNF, the NT-3 receptor, TrkC, and the
Decreased cerebral blood flow, hence decreased oxygen and glucose, leads to ischemic brain injury via complex pathophysiological events, including excitotoxicity, mitochondrial dysfunction, increased intracellular Ca2+, and reactive oxygen species (ROS) generation. Each of these could also
OBJECTIVE
Postoperative atrial fibrillation is a major cause of morbidity and mortality for stroke after cardiac surgery. Both systemic inflammation and oxidative stress play a role in the initiation of postoperative atrial fibrillation after cardiac surgery. The possible association between
(-)-Epigallocatechin-3-gallate (EGCG), the principal constituent of green tea, protects neurons from toxic insults by suppressing the microglial secretion of neurotoxic inflammatory mediators. Voltage-gated proton channels are expressed in microglia, and are required for NADPH oxidase-dependent
(-)-Linalool, a major component of many essential oils, is widely used in cosmetics and flavoring ingredients as well as in traditional medicines. Although various in vitro and in vivo studies have shown that (-)-linalool has anti-convulsant, anti-nociceptive, anti-inflammatory and anti-oxidative
