PZI combined with Se improved the ultrastructure of the skeletal muscle tissue.
The black arrows show the mitochondria, the transparent arrowheads show the ultrastructure of the mitochondria and the arrowheads show the lipid droplets. Scale bars: 2 μm and 500 nm. Model: diabetic group; PZI + Se (L): PZI (50 U/kg/d) + Se (100 μg/kg/d); PZI + Se (H): PZI (100 U/kg/d) + Se (200 μg/kg/d).
