Abstract

Context: Nanotechnology is widely used nowadays in several fields of industry, engineering, and medicine, the biological action mechanisms of AgNPs, which mainly involve the release of silver ions (Ag+), generation of reactive oxygen species (ROS).

Objective: The potential toxicity AgNPs of damages to hepatic cells, hesperidin, and naringin role for their protective effect against the increase of ROS due to AgNPs toxicity. They can be restored, most cellular biochemical parameters, genotoxicity, mutagenicity, and histopathological analysis.

Materials and methods: Toxicity was induced by an oral dose of Ag NPs of (20-100 nm) for one month, after that treated with hesperidin, naringin (100 mg/kg) for three weeks, malondialdehyde (MDA) levels, nitric oxide (NO), glutathione (GSH) and catalase were estimated. Also, aminotransferases (AST and ALT), alkaline phosphatase (ALP), γ-glutamyltransferase (GGT), albumin, and total bilirubin were determined, following Chromosomal aberrations, DNA breaks, and histological analyses.

Results: hesperidin, and naringin treatment, recorded amelioration in most biochemical, genetic, and spermatogenesis disturbances Also, histological Investigations were improved.

Conclusion: Their biological safety problems, such as potential toxicity on cells, tissue, and organs should be paid enough attention, hesperidin and naringin amelioration fundamental alterations, as hepatic architectural and DNA damage, related to its role as an antioxidant and anti-inflammatory agent.
