| Popis: | Graphical abstract The present study sought to investigate the effects of amino-functionalized tannic acid-templated mesoporous silica nanoparticles (TA-MS-NH2 NPs) on giving rats protection against iron-induced liver toxicity. To this end, the TA-MS-NH2 NPs were characterized using field-emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), and Fourier-transform infrared spectroscopy (FTIR). Moreover, 50 Wistar rats were randomly divided into one control group (group 1) and four experimental groups (groups 2- 5) (n = 10), each of which received 100 mg/kg oral normal saline and FeSO4, respectively. Then, post-exposure hepatotoxicity and oxidative stress markers were measured in two intervals, i.e., after 4 and 24 h, followed by the measurement of the acute iron toxicity. Furthermore, hepatotoxicity markers, including the alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total antioxidant capacity (TAC), were measured via Ferric Reducing Antioxidant Power (FRAP) and 2,2,1-diphenyl-1-picrylhydrazyl (DPPH) assays. Also, malondialdehyde (MDA), total thiol groups, advanced oxidation protein products (AOPP), and nitrite/nitrate (NOx) levels were measured as oxidative stress markers in the serum samples. The results indicated that oral administration of iron significantly elevated the liver enzymes and altered the level of oxidative stress markers. It was also found that treatment with TA-MS-NH2 NPs meaningfully protected against hepatotoxicity, decreased ALT, AST, ALP, and significantly improved oxidative stress markers by decreasing MDA, AOPP, and NOx levels and increasing TAC and thiol group contents, proving that TA-MS-NH2 NPs could protect rats against iron-induced acute liver toxicity through their antioxidant features. |
