Combined cerium and zinc oxide nanoparticles induced hepato-renal damage in rats through oxidative stress mediated inflammation

The toxicity profiles of nanoparticles (NPs) used in appliances nowadays remains unknown.

Zusammenfassung:The toxicity profiles of nanoparticles (NPs) used in appliances nowadays remains unknown. In this study, we investigated the toxicological consequences of exposure to cerium oxide (CeO 2 ) and zinc oxide (ZnO) nanoparticles given singly or in combination on the integrity of liver and kidney of male Wistar rats. Twenty (20) rats were allotted into four groups and treated as: Control (normal saline), CeO 2 NPs (50 μg/kg), ZnONPs (80 μg/kg) and [CeO 2 NPs (50 μg/kg) + ZnONPs (80 μg/kg)]. The nanoparticles were given to the animals through the intraperitoneal route, three times per week for four repeated weeks. Results revealed that CeO 2 and ZnO NPs (singly) increased serum AST and ALT by 29% & 57%; 41% & 18%, and co-administration by 53% and 23%, respectively. CeO 2 and ZnO NPs increased hepatic and renal malondialdehyde (MDA) by 33% and 30%; 38% and 67%, respectively, while co-administration increased hepatic and renal MDA by 43% and 40%, respectively. The combined NPs increased hepatic NO by 28%. Also, CeO 2 and ZnO NPs, and combined increased BAX, interleukin-1β and TNF-α by 45, 38, 52%; 47, 23, 82% and 41, 83, 70%, respectively. Histology revealed hepatic necrosis and renal haemorrhagic parenchymal in NPs-treated rats. Summarily, CeO 2 and ZnO NPs produced oxidative injury and induced inflammatory process in the liver and kidney of experimental animals.
