Fig. 1. Body weight (A), relative kidney weight (B), water intake (C) and urine volume (D) in Wistar rats intratracheally instilled with either saline (control) or cerium oxide nanoparticles (CeO₂ NPs) with or without cisplatin (CP) administration. Data are mean ± SEM. Body and kidney weights: saline (n=8), CeO₂ NPs (n=8), CP+saline (n=8) and CP+ CeO₂ NPs (n=8). Water intake: saline (n=6), CeO₂ NPs (n=8), CP+saline (n=8) and CP+ CeO₂ NPs (n=6). Urine volume: saline (n=8), CeO₂ NPs (n=8), CP+saline (n=8) and CP+ CeO₂ NPs (n=7).
