A: Normal control mice show renal corpuscle consists of glomerulus and a two-layered glomerular Bowman’s capsule that encloses glomerulus; the proximal convoluted tubules and distal convoluted tubules. B: Histopathological Changes of mouse kidney for sodium nitrate treated group: In the cortex, there is a sever congestion of renal blood vessels, perivascular cuffing, and infiltration of inflammatory cells in the dilated blood vessels. Extensive distension of Bowman’s space with sever congestion of glomerular capillaries and extensive cellular swelling of proximal and distal convoluted tubules with vacuolar degeneration surrounding proximal and distal convoluted tubules and tubule necrosis with dilation and vacuolar degeneration of proximal and distal convoluted tubules. C: Histopathological Changes of mouse kidney for (Vitamin E -sodium selenite received group): In the cortex, there is a congestion of renal blood vessels, perivascular cuffing, and infiltration of inflammatory cells in the dilated blood vessels. Distension of Bowman’s space. Congestion of glomerular capillaries, proximal and distal convoluted tubules showed cellular swelling. D: Histopathological Changes of mouse kidney for (Vitamin C treated group): In the cortex, there is a congestion of renal blood vessels, perivascular cuffing, and infiltration of inflammatory cells in the dilated blood vessels. Congestion of glomerular capillaries, proximal and distal convoluted tubules showed cellular swelling. E: Histopathological Changes of mouse kidney for sodium nitrate and vitamin E treated group: In the cortex, there is a sever congestion of renal blood vessels, perivascular cuffing, and infiltration of inflammatory cells in the dilated blood vessels. Extensive distension of Bowman’s space with atrophic changes and sever congestion of glomerular capillaries, extensive cellular swelling of proximal and distal convoluted tubules. F: Histopathological Changes of mouse kidney for sodium nitrate and vitamin C treated group: In the cortex, there is a sever congestion of renal blood vessels, perivascular cuffing, and infiltration of inflammatory cells in the dilated blood vessels. Distension of Bowman’s space and sever congestion of glomerular capillaries, extensive cellular swelling of proximal and distal convoluted tubules with cellular debris.
