Abstract
Protection from liver damage and the repercussion of that harm is thought to be crucial for reducing the number of deaths each year. This work was developed to evaluate the possible role of silver nanocomposite prepared using Nigella sativa (N. sativa) aqueous extract against the hepatic damage brought on by thioacetamide (TAA), with particular attention to how they affect the NF-κβ, TNF-α, IL-1β, and COX-2 signaling pathways. There were seven groups of male Wistar rats used as follows: control, saline, N. sativa aqueous extract (NSAE; 200 mg/kg/d), N. sativa silver nanocomposite (NS-AgNC; 0.25 mg/kg/d), TAA (100 mg/kg; thrice weekly), NSAE + TTA, and NS-AgNC + TAA, respectively. The experiment continued for six weeks. The results showed that NS-AgNPs significantly enhanced liver functions (p<0.05) (albumin, ALP, LDH, AST, total protein, ALT, and globulin) and oxidant/antioxidant biomarkers (p<0.05) (H2O2, MDA, PCC, NO, SOD, CAT, GPx, GR, GST and, GSH), contrasted with TAA group. Moreover, a significant (p<0.05) downregulation of the gene expressions (COX-2, TNF-α, IL-1β, and NF-κβ) was also achieved by using silver nanocomposite therapy. These findings have been supported by histological analysis. Collectively, NS-AgNC exhibits more prominent and well-recognized protective impacts than NSAE in modulating the anti-inflammatory, genotoxicity and oxidative stress effects against TAA-induced liver injuries.
