Photomicrograph of cerebellar sections from rats treated with (a) normal saline (control) showing normal histoarchitecture of the cerebellum with viable Purkinje cells (black arrow) and normal molecular layer (ML), Purkinje cells layer (PL), and granular layer (GL). (b) 50 mg/kg of lead (LTG) showing marked degeneration of Purkinje cells (yellow arrow). (c) Quantitative representation of degenerated neuronal cells of the control and LTG groups. *p < 0.05 versus control, n = 5. (Toluidine blue, ×20, scale bar = 100 μm)
