Effect of TAR root extract treatment on hepatic enzymatic antioxidants SOD (A), CAT (B), GPx (C), and GST (D) activity in APAP-induced hepatotoxicity in experimental rats. Bar represents mean ± SE, N = 10 animals per group. Statistical significances: (aP < 0.05, compared with the normal control group; bP < 0.01, compared with the TAR extract group; and cP < 0.05, compared with the APAP group).
