ANTI-INFLAMMATORY ACTIVITY OF NIGELLA SATIVA SILVER NANOPARTICLES: BIOCHEMICAL STUDY
Objective: The aim of this study is to evaluate the anti-inflammatory activity of Nigella sativa silver nanoparticles (NS AgNPs).
Methods: Fourier transform infrared analysis was used to characterize the NS AgNPs and the extract. 2,2-diphenylpicrylhydrazyl assay was done to test the antioxidant potency of NS AgNP. Furthermore, in vitro anti-inflammatory activity of the extract and the NS AgNP was determined by red blood cell (RBC) membrane stabilization assay, protein inhibition assay, and interleukin-1 (IL-1) beta assay.
Results: The NS AgNP exhibited dose-dependent antioxidant property. At the concentration 0.01 mg/ml 80% of radical was scavenged by NS AgNP. Inhibition of protein denaturation assay also suggests that NS AgNP shows the highest activity (70%) when compared with the standard drug aspirin (65%). RBC assay suggests that NS AgNP stabilizes the RBC membrane and prevents leaking. In the enzyme-linked immunosorbent assay method the NS AgNP showed better IL-1 beta inhibition activity when compared to aqueous extract.
Conclusion: From the study, it was inferred that NS AgNPs are more effective when compared to the extract. These results suggest that NS AgNP can be used to treat inflammatory disorders.
