Aqueous black rice (ABR) extract increased the relative number of CD4+CD62L- cells and CD8+CD62L- cells. A, C. Show flow cytometry diagrams, and B, D. Show graphs of the flow cytometry results. The bars in the graphs show the calculated results as the mean ± SD of the relative number of CD4+ and CD8+ cell activations. *P<0.05 indicates a significant difference. The groups in this study included the following groups: Normal; Cancer, DMBA 15 mg/kg BW; Cis, DMBA 15 mg/kg BW + Cisplatin 5 mg/kg BW; ABR1, DMBA 15 mg/kg BW + ABR extract 0.2 g/kg BW; ABR2, DMBA 15 mg/kg BW + ABR extract 0.3 g/kg BW; ABR3, DMBA 15 mg/kg BW + ABR extract 0.4 g/kg BW; and ABR4, DMBA 15 mg/kg BW + ABR extract 0.5 g/kg BW.
