Resveratrol attenuated renal injury after exposure to contrast medium. Blood of the control, contrast-induced nephropathy (CIN), resveratrol + contrast media (RCIN), and resveratrol (RSV) groups of rats were collected 24 h after exposure to contrast medium. Serum (A) creatinine, (B) BUN, (C) Serum neutrophil gelatinase-associated lipocalin (NGAL). Data are presented as mean ± standard error (n = 8 per group). *: p < 0.05 versus control; #: p < 0.05 versus RCIN. RSV = resveratrol; CIN = contrast-induced nephropathy; RCIN = resveratrol before contrast-induced nephropathy. Group comparisons were evaluated by ANOVA followed by Tukey’s test.
