The effect of an ML-diet on cell death in the pancreases of db/db mice. Pancreatic sections from 15-old db/db mice were stained using the TUNEL method (green), anti-insulin antibodies (red) and DAPI (blue). White triangles indicate TUNEL-positive cells. CL, control-diet group; ML, ML-diet group. Scale bar: 50 μm. The ratio of the number of TUNEL-positive β-cells to total β-cell numbers is shown in the right panel. **, P < 0.01 versus control
