Previous experiments have shown that, following experimental fluid-percussion brain injury, cyclo-oxygenase-dependent formation of oxygen radicals prevents arteriolar vasoconstriction in response to hyperventilation. The oxygen radical scavengers superoxide dismutase and catalase restore normal reactivity; however, they are not routinely available for clinical use. The present study tested whet...
A novel free radical scavenger, 3-methyl-1-phenyl-2-pyrazolin-5-one (edaravone), is used for the treatment of acute ischemic stroke and is protective in several animal models of organ injury. We tested whether edaravone is protective against acute liver warm ischemia/reperfusion injury in the rat by acting as a radical scavenger. When edaravone was administered prior to ischemia and at the time...
BACKGROUND Since free radical scavengers of parasite origin like glutathione-S-transferase and superoxide dismutase are being explored as prospective vaccine targets, availability of these molecules within the parasite infecting different hosts as well as different sites of infection is of considerable importance. Using Clinostomum complanatum, as a model helminth parasite, we analysed the effe...
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for the purpose of anti-inflammation, antipyretic, and analgesia. For this aim, they are used for the alleviation of pain, fever, and inflammation associated with rheumatoid arthritis, sports injuries, and temporary pain. However, treatment with NSAIDs may be accompanied by adverse effects such as gastrointestinal damage and platelet...
BACKGROUND AND PURPOSE Apoptotic-like pathways may contribute to brain cell death after intracerebral hemorrhage. In this study, we used a simplified in vitro model of hemoglobin neurotoxicity to map the caspase cascades involved and to document the role of oxidative stress. METHODS Primary neuronal cultures were obtained from rat cerebral cortex and exposed to hemoglobin to induce cell death...
background: alpinia galanga l. belonging to the family zingiberaceae is widely grown in the state of kerala, india. they are effective antioxidant and free radical scavenger under both in vitro and in vivo condition. the efficacy of the isolated flavonoids in conferring protection from radiation induced damages to genomic dna was studied. materials and methods: the bioflavonoids, galangin and k...
