Indian Journal of Experimental Biology. 2014 Apr; 52(4): 332-343.http://imsear.searo.who.int/handle/123456789/150364Renal structural and functional alterations following an exposure to a heterogeneous chemical mixture (HCM) of phthalic acid di butyl ester, 1, 2–dichlorobenzene, cadmium chloride and chromium trioxide, administered through oral gavage in low doses (1/100 and 1/1000 of LD50 value of individual chemical) for 60 days, followed by withdrawal till 120 days resulted in significant rise in kidney lipid peroxidation and fall in the activities of enzymatic antioxidants. However, withdrawal of HCM treatment restored most of these altered parameters. Degenerative changes in the kidney included proximal convoluted tubules devoid of brush boarder with cytoplasmic blebbing, dissolution and sloughing of nuclei. Cortical glomeruli were also affected with epithelial disintegration, pyknosis of podocyte nuclei and mesengial cell hyperplasia. The morphological alterations recovered fully in the low dose compared to the high dose treatment group.enHeterogeneous chemical mixtureKidney structure and functionLipid peroxidationLow dosesOxidative stressAnimalsCadmium Chloride --toxicityChlorobenzenes --toxicityChromium Compounds --toxicityComplex Mixtures --toxicityEnvironmental ExposureKidney --drug effectsKidney --physiologyKidney --ultrastructureKidney Tubules, Proximal --drug effectsKidney Tubules, Proximal --physiologyKidney Tubules, Proximal --ultrastructureMalePhthalic Acids --toxicityRatsRats, WistarImpairment of renal structure and function following heterogeneous chemical mixture exposure in rats.Article
