Cardiac oxidative stress and apoptosis in different experimental groups. (a) Representative images of DHE staining for myocardial tissues (red, DHE; blue, DAPI) and the average fluorescence intensity were summarized. (b) Representative images of immunofluorescence for apoptotic cells (red, caspase-3; blue, DAPI). The apoptotic index was quantified by Image-Pro Plus software. (c) Representative images of immunofluorescence for apoptotic cells (green, TUNEL; blue, DAPI). The apoptotic index was quantified by Image-Pro Plus software. Results are from 3-4 images per group. Data are expressed as . , , . Con: control group; Low: low STZ treated group; High: high STZ treated group. Scale bar, 12.5 μm.
