(A) Comparison of intracellular lysate concentrations of pure EFA with and without GSH (*** indicate p < 0.001). Values are means ± S.D. of three independent experiments. (B,C) represent the uptake of rhodamine123-containing pure EFA without and with GSH by the THP-1 monocyte/macrophage cells respectively. Cells were incubated with sample preparation for 24 h at 37 °C. Fluorescent images were acquired at ×40 original magnification. Nucleus is stained with DAPI (blue); R123-loaded EFA shown as green fluorescence.
