摘要

Background

The present investigation assessed the potential ameliorating effect of zinc oxide resveratrol nanoparticles against Levofloxacin-induced liver damage in rats.

Methods

Fifty adult Wistar rats were split up into five groups at random. (n = 10). GI, (control): was orally gavaged with distilled water; G II (LFX): was orally given levofloxacin (LFX) (40 mg/kg BW). G III was orally administered zinc oxide resveratrol nanoparticles (Zn- RSV) (20 mg/kg BW). G IV: was given Zn-RSV as GIII and LFX as GII simultaneously (LFX + Zn-RSV). GV: was given LFX as GII and zinc oxide (20 mg/kg BW) (LFX + Zn). All treatments were given every other day for two months.

Results

Administration of zinc oxide resveratrol nanoparticles (Zn-RSV NPs) significantly mitigated levofloxacin (LFX)-induced hepatotoxicity in rats. Compared to LFX-treated groups through improved liver function via lowered serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, and creatinine levels. Also, reduced oxidative stress markers, decreased malondialdehyde (MDA) and nitric oxide (NO) levels in hepatic tissue and enhanced antioxidant defenses, increased superoxide dismutase (SOD) and catalase activities, restoring them to near-normal levels. Modulated apoptosis: Downregulated pro-apoptotic BAX expression and upregulated anti-apoptotic Bcl-2 expression, promoting cell survival. Zn-RSV NPs alleviated histopathological changes through mitigated LFX-induced degenerative and necrotic changes in hepatic tissue, preserving tissue architecture.

Conclusions

This study revealed that zinc oxide resveratrol nanoparticles modulated levofloxacin-induced hepatic damage by lowering inflammation and oxidative stress while increasing the activity of antioxidant enzymes in rat hepatic tissue.
