thirty minutes of total cerebral ischemia ( decapitation ) decreased total glutathione ( gsh + gssg ) by 7 % but had no detectable effect on the concentration of oxidized glutathione ( gssg ) , reduced ascorbate , or total ascorbate , in a model of reversible , bilateral hemispheric ischemia ( four-vessel occlusion ) no changes in glutathione or ascorbate were detected after 30 min of ischemia .
