Toxicity and Hepatoprotective Effects of ZnO Nanoparticles on Normal and High-Fat Diet-Fed Rat Livers: Mechanism of Action.

This experiment aimed to evaluate the beneficial and toxic properties of synthetic zinc oxide nanoparticles (ZnO NPs) on the liver of normal and high-fat diet (HFD) fed-rats. The ZnO NPs were synthesized and, its characterizations were determined by different techniques. Effect of ZnO NP on cell viability, liver enzymes and lipid accumulation were measured in HepG2 cells after 24 h.
