(B) AlCl3: neuronal cell degeneration,neuropil vacuolation (V) and disorganization as well as increasedpyknotic (arrow) and apoptotic cells (ap). Inflammatory cellswere observed (Ib). (C) AlCl3 and 10 mg/kg cannabis showingmoderated neuropil vacuolation (V) and pyknotic cells (arrow).(D) AlCl3 and 20 mg/kg cannabis showing slight pyknotic cells(arrow).
