Figure 4: Effects of pretreatment with different soybeans extracts on TPA-mediated enhancement in the susceptibility of cutaneous skin for iron ascorbate-induced lipid peroxidation in mice: hydroalcoholic extract (HE), spray-dried soybean extract at 115°C/45% (SE1), and spray-dried soybean extract at 150°C/70% (SE2). Bars represent means ± SD of three separate experiments with 3 animals per group per experiment. *Significant () when compared with acetone treated control group. **Significant () when compared with acetone treated control group and TPA treated control group. ***Significant () when compared with TPA treated control group and HE, SE1, and SE2 treated groups.
