Furthermore, compared with the Cont group, the urinary concentrations of NGAL were significantly increased 24 h after iohexol injection in the PC–AKI group (P < 0.001); however, resveratrol treatment markedly reduced levels of uNGAL induced by iohexol in the Res+PC–AKI group (P = 0.04; Figure 1). This evidence concerns the gene LCN2 and acute kidney injury.
