The effects on urine and serum profiles of intravenous injection of diatrizoate, iohexol, or saline were studied in male rats pretreated with steroids or saline. Using urinary albumin, glucose, sodium, and the enzymes lactate dehydrogenase (LDH), gamma-glutamyltransferase (GGT), and N-acetyl-beta-D-glucosaminidase (NAG) as markers of glomerular and tubular function, it was found that diatrizoate caused temporary glomerular and tubular dysfunction; the effect was independent of the kind of pretreatment. Iohexol did not cause increased glomerular permeability in steroid- and saline-pretreated rats. When used following saline, iohexol induced increased excretion of three tubular components, whereas iohexol plus steroids caused increased excretion of all five tubular components. The dysfunctional effect of iohexol plus steroids was less than that of diatrizoate plus steroids. The serum components revealed no abnormalities induced by either contrast media or methylprednisolone. Pretreatment with steroids has no effect on the glomerular or tubular dysfunctional effect of diatrizoate, whereas it worsens the temporary tubular dysfunctional effect of iohexol in rats.

UI MeSH Term Description Entries
D007275 Injections, Intravenous Injections made into a vein for therapeutic or experimental purposes. Intravenous Injections,Injection, Intravenous,Intravenous Injection
D007455 Iodine A nonmetallic element of the halogen group that is represented by the atomic symbol I, atomic number 53, and atomic weight of 126.90. It is a nutritionally essential element, especially important in thyroid hormone synthesis. In solution, it has anti-infective properties and is used topically. Iodine-127,Iodine 127
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
