Figure 8: Section of kidney (A) control showing normal structure of renal tubule and glomaruli (G); (B): 50 mg/kg PEG treated animal showing cloudy swelling, and vacuolar degeneration, sings of fibrosis and inflammatory cellular infiltration., thickening of basement membrane and narrow lumen. (C) 100 mg/kg of PEG showed dilatation and of congestion of blood vessel. Bleeding in interstitial space; some glomeruli showed completely degenerated others showed lobulation. Vacuolar degeneration in some tubular epithelial cells. (D) 200 mg/kg of PEG showing sever vacuolar degeneration (left lower) and cloudy degeneration (upper right), interstitial cellular infilteration. Some glomeruli showed lobulation and others completely degenerated.
