Evaluation of in vivo cytogenetic toxicity of europium hydroxide nanorods (EHNs) in male and female Swiss albino mice.

Our group already demonstrated that europium hydroxide nanorods (EHNs) show none or mild toxicity in C57BL/6 mice even at high dose and exhibited excellent pro-angiogenic activity towards in vitro and in vivo models. In the present study, we evaluated the in vivo cytogenetic toxicity of intraperitoneally administered EHNs (12.5-250 mg/kg/b.
