Synthesis and characterization of newly synthesized neodymium zirconate zinc sulfide nanocomposite and its effect on selected aspects of albino mice behavior.

Present study was conducted to report the effect of variable doses of neodymium zirconate zinc sulfide nanocomposite on behavior of albino mice of both sexes. Five-week-old albino mice (C57BL/6 strain) of both sexes were orally treated either with 10 mg (low dose) or 20 mg/ml saline/kg body weight (high dose) of neodymium zirconate zinc sulfide nanocomposite for 11 days. An untreated control group was maintained in parallel for same duration that received saline solution orally. A series of neurological (rotarod, light and dark box, open field, and novel object recognition) tests were conducted in all treatments. Oral supplementation of both low and high dose of nanocomposite significantly reduced the rotarod test performance as well as stretch attend reflex in male mice during light dark box test. Male mice treated with high dose of neodymium zirconate zinc sulfide nanocomposite had significantly increased time mobile and decreased time immobile than control group during open field test. Female mice treated with 10 mg/ml saline/kg body weight of neodymium zirconate zinc sulfide nanocomposite had significantly more line crossing during trial 1, and they spend more time with object A during trial 2 of novel object recognition test than their saline-treated control group. Change in body weight remained unaffected when compared between nanocomposite treated and untreated albino mice. In conclusion, we are reporting that both the applied doses of neodymium zirconate zinc sulfide nanocomposite are drastically affecting the muscular activity and exploratory behavior in male albino mice, while the studied behavioral tests, in general, remained unaffected in female albino mice.
