Abstract：
:Using a consistent, reproducible and reliable cortical focal ischemia in rat (permanent unilateral occlusion of the left middle cerebral artery & the ipsilateral common carotid artery [MCAo + CCAo] with a 1 h temporary occlusion of the contralateral CCA), the levels of four major membrane fatty acids (palmitic, C16:0; stearic, C18:0; Oleic, C18:1 and arachidonic, C20:4) were analyzed at 3, 36 and 72 h, and 2 and 4 wk following ischemia to determine the critical point of irreversibility of the cellular plasma membrane disorganization in primary ischemic (Area 1, parietal cortex) and peri-ischemic (Area 2, tempero-occipital cortex) areas. The cortical focal ischemia resulted in time dependent differential loss in four of these major membrane fatty acids. The quantitative differences among primary and peri-ischemic areas reflected the different degree of ischemic injury inflicted to these regions. Acute treatment with ganglioside GM1 protected the further losses of all of these fatty acids and differentially restored their levels in these various injury sites over periods of time. The changes in levels of these membrane fatty acids indicate that the primary ischemic area suffers an irreversible injury and peri-ischemic area suffers reversible injury. After acute treatment (< 2 h) with ganglioside GM1, a partial recovery was observed in primary ischemic area and complete recovery was observed in peri-ischemic areas. These studies support the hypothesis that, ischemia leads to a irreversible plasma membrane disorganization which underlies the eventual cell death, and protection and restoration of these membrane changes by drugs, such as ganglioside GM1 leads to neuroprotection against ischemic injury.
