Lipopolysaccharide (LPS)-induced renal oxidant injury and the role of nitric oxide (NO) were evaluated using the inducible nitric oxide synthase (iNOS) inhibitor l-iminoethyl-lysine (l-NIL). One group of male rats received LPS (Salmonella minnesota; 2 mg/kg, i.v.). A second group received LPS plus l-NIL (3 mg/kg, i.p.). A third group received saline i.v. At 6 hr, iNOS protein was induced in the kidney cortex, and plasma nitrate/nitrite levels were increased from 4 ± 2 nmol/mL in the Saline group to 431 ± 23 nmol/mL in the LPS group. The value for the LPS + l-NIL group was reduced significantly to 42 ± 9 nmol/mL. LPS increased blood urea nitrogen levels from 13 ± 1 to 47 ± 3 mg/dL. LPS + l-NIL reduced these levels significantly to 29 ± 2 mg/dL. Plasma creatinine levels were unchanged in all groups. Tissue lipid peroxidation products in the kidney were increased from 0.16 ± 0.01 nmol/mg in the Saline group to 0.30 ± 0.03 nmol/mg in the LPS group. LPS + l-NIL reduced the values significantly to 0.22 ± 0.02 nmol/mg. Intracellular glutathione levels were decreased in the kidneys from 1.32 ± 0.1 nmol/mg in the Saline group to 0.66 ± 0.08 nmol/mg in the LPS group. LPS + l-NIL increased the levels significantly to 0.99 ± 0.13 nmol/mg. LPS increased the 3-nitrotyrosine-protein adducts in renal tubules as detected by immunohistochemistry, indicating the generation of peroxynitrite. l-NIL decreased adduct formation. These data indicated that LPS-induced NO generation resulted in peroxynitrite formation and oxidant stress in the kidney and that inhibitors of iNOS may offer protection against LPS-induced renal toxicity.
