Immunostaining of kidney samples following 6 weeks exposure to PbO-NPs. a-c PCNA in kidney tissue. Arrows indicate PCNA-positive cells in kidney. An enormous amount of positive cells is in infiltrates. d-f TUNEL in kidney tissue. Arrows indicate TUNEL-positive cells, individually located mostly in infiltrates. g-i Na-K ATPase in control samples. Cells with high positivity of enzyme are epithelial cells of distal tubules. j-l Na-K ATPase in treated samples. Arrows indicate decreased activity of enzyme in the epithelial cells of proximal tubules. Scale bar in all panels = 100 μm
