摘 要:Aim:To observe the effects of stearic acid,a long-chain saturated fatty acidconsisting of 18 carbon atoms,on brain(cortical or hippocampal)slices insultedby oxygen-glucose deprivation(OGD),glutamate or sodium azide(NAN3)in ***:The activities of hippocampal slices were monitored by population spikesrecorded in the CA1 region,In vitro injury models of brain slice were induced by10min of OGD,1 mmol/L glutamate or 10 mmol/L *** 30min of pre-incubation with stearic acid(3-30μmol/L),brain slices(cortical or hippocampal)were subjected to OGD,glutamate or NaN3,and the tissue activities were evalu-ated by using the 2,3,5-triphenyltetrazolium chloride ***886 [5 mmol/L;a noncompetitive inhibitor of proliferator-activated receptor(PPAR-α)] or BADGE(bisphenol A diglycidyl ether;100μmol/L;an antagonist of PPAR-γ)were testedfor their effects on the neuroprotection afforded by stearic ***:Viabilityof brain slices was not changed significantly after direct incubation with ***,glutamate and NaN3injury significantly decreased the viability ofbrain *** acid(3-30 μmol/L)dose-dependently protected brain slicesfrom OGD and glutamate injury but not from NaN3injury,and its neuroprotectiveeffect was completely abolished by ***:Stearic acid can protectbrain slices(cortical or hippocampal)against injury induced by OGD or *** neuroprotective effect may be mainly mediated by the activation of PPAR-γ.
