Figure 1: Light microscopic examination of heart sections with H and E staining: (A) section of the control group showed normal cardiac muscle cells parallel to each other with a preserved structure; (B*) section of the DOX group showed inflammatory cell infiltration (plasma cells and lymphocytes) and muscle degeneration; (B**) section of the DOX group showed extensive hemorrhage and degeneration; (C*) section of the QCT + DOX group showed mild inflammatory infiltrate ‘lymphocytes;’ (C**) section of the QCT + DOX group showed mild degenerative changes; (D) section of the QCT group showed normal cardiomyocytes nearly similar to the control group (H and E, ×100 for A, B, C, and D). DOX, doxorubicin; H and E, hematoxylin and eosin; QCT, quercetin.
