Varying Doses of Rare-Earth-Metal-Based Neodymium Zirconate Zinc Sulfide Nanocomposite Disrupt Blood and Serum Parameters, as well as Markers of Oxidative Stress in the Selected Organs of Albino Mice

Abstract

Despite extensive industrial use, the biocompatibility of nanocomposites has not been extensively explored. The present study was designed to report the effect of variable doses of a newly synthesized nanocomposite, Neodymium Zirconate Zinc Sulfide, on selective serum and complete blood count parameters and on the oxidative stress markers from the vital organs of albino mice. Albino mice (C57BL/6 strain, 5 weeks old) of both sexes were orally treated for 11 days, either with 10 mg (low dose) or 20 mg/mL saline/kg body weight (high dose) of Neodymium Zirconate Zinc Sulfide nanocomposite. A control group that was not treated with the nanocomposite but with saline solution was also maintained. Data analysis revealed that high-dose nanocomposite-treated male mice had significantly reduced hemoglobin concentration as compared to the control males. Female mice treated with both doses of nanocomposite had higher serum triglyceride levels than controls. High-dose-treated female mice had elevated serum cholesterol concentration compared to their saline-treated controls. Oxidative stress marker analysis from selected organs indicated that concentrations of malonaldehyde (MDA) in the kidney and liver, Superoxide dismutase (SOD) levels in the brain and catalase in the kidney of male mice treated with the nanocomposite were significantly higher than in the control group, whereas SOD in the heart, MDA in the heart and kidney and catalase levels in the kidney were significantly disrupted in female mice compared to their respective controls.
