CAT and neoplasm: In this study, compared with the Nor group, inoculation of S180 tumour in the Con group significantly reduced GSH and GST levels in mice liver (p < 0.01 and p < 0.05, respectively) (Figure 3(A,B)) and kidney (both p < 0.01) (both p < 0.01) (Figure 3(D,E)) without obvious effects on GPx (Figure 3(C,F)), SOD (Figure 4(A,C)) and CAT (Figure 4(B,D)), either in the liver or in the kidney.
