| Research Abstract |
Oxidative stress(production of hydroxyl radicals, the most toxic reactive oxygen species) was enhanced in the brain during severe carbon monoxide(CO) poisoning with 70% CO-hemoglobin in blood, but not moderate CO poisoning with 50% CO-hemoglobin in blood. The present results suggest that the enhancement of oxidative stress might be due to CO itself, but not hypoxia induced by CO poisoning, and mediated through activation of intracellular cAMP signaling pathways via purine P2Y11-like receptors.
