On yedi adet Yeni Zelanda cinsi tavşan (4-6 kg) iki guruba ayrıldı. Grup I kontrol grubu (n=7) olarak kullanılırken Grup II’ye (n=10) yüksek doz Tolüen verildi (876 mg/kg/ip). Üç saatlik deney periyodunun sonunda öldürülen hayvanlardan biyokimyasal analizler için kan serumu ve beyin doku örnekleri % 10’luk nötral formaline alınıp parafine gömülerek kesildi (5 μm). H&E (hematoksilen-eozin), Crystal violet boyamaları, Na, K, GSH, MDA ve NO kan serum seviyeleri analiz edildi. Bu çalışma sonucunda Tolüen verilen tavşanlarda önemli ölçüde histopatolojik bozukluklar ve ciddi amiloit plak oluşumu gözlemlenmiştir. Tolüen grubunda Na, K, MDA, kan serumu seviyelerinde önemli ölçüde artış görülmüşken, GSH ve NO seviyelerinde anlamlı derecede azalma izlenmiştir. Bu çalışma sonucunda yüksek doz tolüenin beyin korteksinde akut dönemde ciddi hasarlar oluşturabileceği gösterilmiştir.
