ABSTRACT
To explore the effect of tea polypheonls (TP) combined with ascorbic acid on the activity of antioxidant enzymes of rats induced by silica, the activities of nitric oxide synthase (NOS), glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD) were determined. Compared with the normal saline control group, the activities of SOD and NOS of the silica-induced group increased (P < 0.05), but the activity of GSH-PX was gradually decreased. The activities of SOD and NOS decreased and GSH-PX increased in the intervention group. It is concluded that TP combined with ascorbic acid can alleviate the abnormal change of antioxidant enzymes in rats induced by silica.
