Potassium dichromate genotoxicity, Nanochitosan, Nanocurcumin, Nephrotoxicity, Testicular damage


Objective: The purpose of this work is to examine the protective effect of nanocurcumin and nanochitosan supplementation against potassium dichromate toxicity in male mice.

Methods: Male albino mice weighing 25-30 gm were divided into six groups; the first group received saline. Second and third groups were given oral dose of nanocurcumin and nanochitosan respectively for 5 d. Fourth group was injected subcutaneously with a single dose of potassium dichromate for 24 h. Group five and six were administrated nanocurcumin and nanochitosan, respectively prior to potassium dichromate. Animals were anesthetized by ether anesthesia then bone marrow was harvested for chromosomal examination and epididymal sperms were collected for sperm morphology, while Kidneys and testes were collected for western blot and biochemical analysis.

Results: Potassium dichromate induced significant (P≤0.05) increase in chromosome and sperm abnormalities as well as testicular and renal MDA, renal MPO, renal contents of IL-18 and IGF-1, testicular contents of caspase 3 and cytosolic cytochrome c, a reduction in testosterone level, and GPx of renal and testicular tissues compared to control group. Pretreatment with both types of nanoparticles showed significant (P≤0.05) mitigation against most alterations induced by potassium dichromate; moreover, nanochitosan gave more significant (P≤0.05) improvement against chromosome and sperm abnormalities than nanocurcumin.

Conclusion: The present study revealed that the selected nanoparticles have antioxidant as well as antigenotoxic properties against toxicity of potassium dichromate.
