摘要
A Review] Endothelial cells produce both superoxide and nitric oxide. Nitric oxide and superox- ide are known to react rapidly to form the stable peroxynitrite anion. Peroxynitrite mediates the oxidation of protein, lipid, deoxyribose and inhibits mitochondrial electron transport. Peroxynitrite may break DNA strands and activate poly(ADP - ribose) syntheatase. If the reaction is excessive, it results in a depletion of intracelular NAD+ and ATP. There is ultimately cell death.
