This experiment was premeditated to probe the toxic impact of Silver Nanoparticles (AgNPs) upon liver function parameters in male rats, as well as to demonstrate the protective effect of Tinospora cordifolia (T.C) against liver function disorders caused by AgNPs. Twenty-four rats were classified into four packs, six ones for every pack. Rats were included by control animals without treatment, while the AgNPs group included rats treated with 50μl/kg / day AgNPs. In the AgNPs + T.C group, rats were co-administered of AgNPs at a dose of 50μl/kg with T.C at a dose of 400 mg/kg. Whereas, animals of the T.C pack were treated with 400 mg/kg of T.C. The duration of the experiment was 28 days. After blood samples were taken at the conclusion of the experiment. The levels of biochemical parameters (liver enzymes) such as alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase were evaluated to detect liver function abnormalities. Thwe Pw A t e dewoe t ste user e dnoAiwoe se dsnd disnte dnirease in the activity of serum liver enzymes in comparison to the control group (p < 0.05).While T. cordifolia co-treatment significantly reduced the levels of activities of those enzymes. Therefore, it can be considered that T. cordifolia effectively contributes to the protection against liver dysfunction caused by AgNPs in rats.
