Photomicrographs of kidney sections from control and treated groups, stained with hematoxylin and eosin H&E (10X). Kidney section of control group showing normal architecture of kidney tubule (T) and glomerulus (G) (a). Kidney section of AlCl3- treated group showing intensive inflammatory infiltration (arrow) and shrinkage of glomerulus (G) (b). Kidney section of propolis treated group showing normal architecture of kidney tubule (T) and glomerulus (G) (c). Kidney section of AlCl3 combined with propolis treated group showing recovered glomerulus (G) and no inflammatory cells were detected as compared to aluminum treated group (d). Kidney section of the AlCl3 treatment for one month followed by administration of AIC13 combined with propolis for another month group showing the protective role of propolis since no glomerular shrinkage or inflammatory cells were detected (e)
