Photomicrographs of kidney sections from rats treated with (A) Normal saline (control) showing normal histo-architecture with glomerulus (green arrow), proximal convoluted tubules (PCT) and distal convoluted tubules (DCT) (scored as 0). (B) 50 mg/kg of lead (LTG) showing congested hypercellular glomerulus (yellow arrow), prominent cytoplasmic vacuolation (fatty degeneration), cellular necrosis (black star) and glomerular atrophy, tubular dilatation (yellow arrowhead) and collapsed tubular tuft (yellow star) (scored as 3). (H and E, X40, scale bar = 50 µm).
