摘要
The level of lipid peroxidation and cellular necrosis in rat living brain slices during brain ischemia-hypoxia injury have been observed using a laser confocal scanning microscope (LCSM) with double labeling of fluorescent probes D-399 (2, 7-dichlorofluorescin diacetate) and propidium iodide (Pl). The hypoxia and/or reoxygenation injury in rat brain slices is markedly decreased by pretreatment with L-NG-nitro-arginine (L-NNA) and N-acetylcysteine (NAC), showing that the nitric oxide (NO) and other free radicals play an important role in brain ischemia-hypoxia injury.
