Photomicrographs of rats’ renal tissue. a From the control group showing the renal corpuscle containing the glomerulus (G) and surrounded by Bowman’s space (B) and proximal (P) and distal (D) convoluted tubules. b From the GEN group showing atrophied glomerulus (G) and dilated Bowman’s space (B). Some renal tubules display vacuolated cells (V) and shed nuclei (arrowhead); others display dilated lumen (L) and hyaline cast (C). c From the GEN+ NaHS–treated group showing the glomerulus (G), Bowman’s space (B), and proximal (P) and distal (D) convoluted tubules with apparently normal structure. Note the congested capillary tuft (arrow). d From the GEN+ NaHS + ZnPP–treated group showing the glomerulus (G), Bowman’s space (B), and proximal (P) and distal (D) convoluted tubules with apparently normal structure. Note the congested capillary tuft (arrow), the shed nuclei (arrowhead), and hyaline cast (C). H&E, × 400
