Figure 5: Histopathology of rat brain (hippocampus)section) with H and E x400 (a) Normal control group showing normal histological finding. (Black arrow- Normal Neuron). (b)SCO (1mg/kg) (Black arrow- severe neuronal degeneration, neuronophagia and blue arrow pyknotic nucleus) (c) CDE (100mg/kg) + SCO group showing moderate neuronal degeneration with neurophagia with congestion of blood vessels. (Black arrow Moderate edema and Blue arrow shows moderate neurodegeneration) (d) CDE (200mg/kg) + SCO showing neuronal degeneration. (Black arrow-mild neuronal degeneration) e) CDE (400mg/kg) + SCO group (Black arrow show mild congestion and blue arrow shows mild neurodegeneration) (f) Donepezil (3mg/kg) + SCO group showing minimal neuronal degeneration. (Black arrow - Mild congestion, Blue arrow minimal neurodegeneration). *CDE: Cynodon dactylon hydroethanolic extract; SCO: Scopolamine
