Figure 3.

Effect of NDGA on TPA-induced (a) lipid peroxidation, (b) H2O2 production and (c) xanthine oxidase activity in skin of mice from different treatment groups. Values are expressed as means ± SE (n = 6) of nmol TBARS formed/h/g tissue, nmol H2O2/h/g tissue and μg uric acid/mg protein, respectively. Significant differences are indicated by ***P < .001 when compared with control animals (Group I) and # P < .05 and ### P < .001 and when compared with TPA-treated animals (Group II).
