Fig. 3

Sample of dentate gyrus from sarin-poisoned rat treated with HI-6 and trimedoxime (hematoxylin-eosin, 600fold original magnification). The microphotograph displays a boundary between polymorphic (upper) and granular (lower) layer. The treatment significantly reduced the pathological finings in this animal, nevertheless, a red cell with chromatolysis (black arrow) and several neuronal vacuoles (white arrow indicates an example) could be observed
