Urine chemical profiles were followed for three or nine days after intravenous injection of diatrizoate, iohexol, or saline in 30 rats, where a tubulointerstitial nephropathy was induced by gentamicin given over an eight-day period. Another ten rats injected with saline served as controls. Compared to injection of saline, both iohexol and diatrizoate induced dysfunction. The excretion of the cytoplasmic enzyme lactate dehydrogenase was significantly greater following iohexol than following diatrizoate. No significant differences between the two media were shown by the various serum components examined. Among the gentamicin-treated rats, light microscopy showed prolonged occurrence of tubular necrosis and a more intensive round cell infiltration following iohexol than following diatrizoate and saline. Both contrast media induced further temporary renal dysfunction in rats with gentamicin nephropathy; iohexol induced more morphologic changes than diatrizoate.

UI MeSH Term Description Entries
D007472 Iohexol An effective non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures. Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality. Compound 545,Exypaque,Iohexol 350,Nycodenz,Omnipaque
D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D007683 Kidney Tubular Necrosis, Acute Acute kidney failure resulting from destruction of EPITHELIAL CELLS of the KIDNEY TUBULES. It is commonly attributed to exposure to toxic agents or renal ISCHEMIA following severe TRAUMA.

D003973 Diatrizoate A commonly used x-ray contrast medium. As DIATRIZOATE MEGLUMINE and as Diatrizoate sodium, it is used for gastrointestinal studies, angiography, and urography.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D005839 Gentamicins A complex of closely related aminoglycosides obtained from MICROMONOSPORA purpurea and related species. They are broad-spectrum antibiotics, but may cause ear and kidney damage. They act to inhibit PROTEIN BIOSYNTHESIS.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014556 Urine Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.
