Effects of LGG-s pretreatment on hepatic and ileal reactive oxygen species (ROS) formation. Cryostat sections of liver (A) or ileum (B) were incubated with 5 μM dihydroethidium (Molecular Probes, Eugene, OR) for 30 min at 37°C in the dark. The superoxide anion-catalyzed ethidium red fluorescence was examined under fluorescence microscopy.
