Study protective role Camellia sinensis L. (black tea) and silver, Zn oxide nanoparticles on antioxidant-oxidant enzymes and biochemical level against paracetamol overdose in adult male rats

Abstract

This study aims to measure the preventive effect of the silver, Zn oxide nanoparticles, and Camellia sinensis L. (black tea) on liver toxicity caused by the paracetamol drug. The Nanomaterials, with a practical size range of 33–40nm, black tea was extracted by Soxhlet apparatus using methanol alcohol at a concentration (80%); design in this study, 60 adult male rats weighing between 195 and 330 g and aged 11 to 14 weeks were used. They were kept in a relatively regulated setting with a temperature of 25Co at the University of Karbala’s animal facility. They received food. There were eight rat group divisions. G1: just received saline solution (0,85%) as the control. G2: 250 milligrams of black tea and 250 milligrams of paracetamol per kilogram of body weight. G3: 400 milligrams of C. sinensis L. and 250 milligrams of paracetamol per kilogram of body weight. G4: injection of 0.3 milligrams of zinc nanoparticles and 250 milligrams of paracetamol per kilogram of body weight. G5: injection of 0.5 milligrams of zinc nanoparticles and 250 milligrams of paracetamol per kilogram of body weight. G6: injection of 0.3 milligrams of silver nanoparticles and 250 milligrams of paracetamol per kilogram of body G7: injection of 0.5 milligrams of silver nanoparticles and 250 milligrams of paracetamol per kilogram of body, G8: 250 milligrams of paracetamol per kilogram of body administered intravenously, the blood bled for 30 days after receiving all dosages orally once daily for 21 days. When rats were given injections of 0.5 mg of nanoparticles and when injections of 250 mg of a black tee., it was discovered that the concentration of Malondialdehyde MDA, Lipid Peroxidation LPO, Triacylglycerid, cholesterol levels, and glucose decreased significantly. In contrast, Glutathione peroxidase GPX and protein levels are increased considerably. This was due to the injections’ preventive and antioxidant action against the oxidative stress brought on by the paracetamol height dose. Keywords: silver nanoparticles, Zn oxide nanoparticles, Camellia sinensis L., paracetamol.
